For example, oleic acid and elaidic acid are both unsaturated fatty acids with the chemical formula C 9 H 17 C 9 H 17 O 2. Atrial tachycardia A type of arrhythmia that begins in the hearts upper chambers (the atria) and causes a very fast heart rate of 160 to 200 beats a minute. The formula for acyclic saturated hydrocarbons (i.e., alkanes) is C n H 2n+2. [32], As of 2015, many specific biological targets for resveratrol had been identified, including NQO2 (alone and in interaction with AKT1), GSTP1, estrogen receptor beta, CBR1, and integrin V. But that bag of potato or corn chips is full of salt and, often, unhealthy saturated or trans fats. However, hydrogenation breaks double bonds in an unsaturated cis-fat, making a saturated trans fat. In a trans isomer, the dipoles of the substituents will cancel out [6] due to being on opposite sides of the molecule. Septum The muscular wall dividing a chamber on the left side of the heart from the chamber on the right. One review concluded that resveratrol had no effect on neurological function, but reported that supplementation improved recognition and mood, although there were inconsistencies in study designs and results. Usually caused by a serious arrhythmia. Petroleum (literally "rock oil") and coal are generally thought to be products of decomposition of organic matter. Paralysis may be temporary or permanent. Pulmonary valve The heart valve between the right ventricle and the pulmonary artery thatcontrols blood flow from the heart into the lungs. Atrioventricular block An interruption or disturbance of the electrical signal between the hearts upper two chambers (the atria) and lower two chambers (the ventricles). Alcohols and organic acids join to form esters. Pulmonary vein The blood vessel that carries newly oxygenated blood from the lungs back to the left atrium of the heart. Magnetic resonance imaging (MRI) A technique that produces images of the heart and other body structures by measuring the response of certain elements (such as hydrogen) in the body to a magnetic field. Shunt A connector that allows blood to flow between two locations. Trans isomers also tend to have lower densities than their cis counterparts. Heart block General term for conditions in which the electrical impulse that activates the heart muscle cells is delayed or interrupted somewhere along its path. An alternate spelling, retinol palmitate, which violates the -yl organic chemical naming convention for esters, is also frequently seen. Mitral valve prolapse A condition that occurs when the leaflets of the mitral valve between the left atrium and left ventricle bulge into the atrium and permit backflow of blood. Lipid A fatty substance that is insoluble (cannot be dissolved) in the blood. Pensions, property and more. Resveratrol (3,5,4-trihydroxy-trans-stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin produced by several plants in response to injury or when the plant is under attack by pathogens, such as bacteria or fungi. [61][62][63], InChI=1S/C14H12O3/c15-12-5-3-10(4-6-12)1-2-11-7-13(16)9-14(17)8-11/h1-9,15-17H/b2-1+, Except where otherwise noted, data are given for materials in their. Most anthropogenic (human-generated) emissions of greenhouse gases are carbon dioxide from the burning of fossil fuels, and methane released from natural gas handling and from agriculture. Transcatheter intervention Any of the noninvasive procedures usually performed in the cardiac catheterization laboratory. For a single CC bond it is alkane metathesis, for a double CC bond it is alkene metathesis (olefin metathesis), and for a triple CC bond it is alkyne metathesis. The IUPAC standard designations E and Z are unambiguous in all cases, and therefore are especially useful for tri- and tetrasubstituted alkenes to avoid any confusion about which groups are being identified as cis or trans to each other. There is no chance of further chemical interaction due to hydrogen saturation. Clots can also form inside an artery when the arterys walls are damaged by atherosclerotic buildup, possibly causing a heart attack or stroke. The storage reaction is catalyzed by LRAT, and the inverse is catalyzed by REH. A related type of isomerism in octahedral MX3Y3 complexes is Maze surgery A type of heart surgery that is used to treat chronic atrial fibrillation by creating a surgical maze of new electrical pathways to let electrical impulses travel easily through the heart. 2 Superior vena cava The large vein that returns blood from the head and arms to the heart. Dissecting aneurysms usually happen in the aorta,the large vessel that carries blood from the heart to other parts of the body and can cause sudden death. The saturated fatty acid stearic acid (C18:0), the monounsaturated oleic acid (C18:1), and the polyunsaturated linoleic acid (C18:2) decrease LDL and increase HDL to various degrees. Sphygmomanometer An instrument used to measure blood pressure. [27] Other bacteria such as Lutibacterium anuloederans can also degrade hydrocarbons. Ischemia Decreased blood flow to an organ, usually due to constriction or obstruction of an artery. Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae but in some other organisms Thus, a saturated fatty acid, having no double bonds, has the maximum number of hydrogen atoms for a given number of carbon atoms that is, it is "saturated" with hydrogen atoms. Circulatory system Pertaining to circulation of blood through the heart and blood vessels. Lipoprotein A lipid surrounded by a protein; the protein makes the lipid soluble (can be dissolved) in the blood. [5][6] These two alkenes are precursors to polymers, including polyethylene, polystyrene, acrylates,[7][8][9] polypropylene, etc. Also called the Maze procedure. The condition can be associated with progressive mitral regurgitation. Internal mammary arteryA durable artery in the chest wall often used as a bypass graft in coronary artery bypass surgery. In the trans isomer on the other hand, this does not occur because the two CCl bond moments cancel and the molecule has a net zero dipole moment (it does however have a non-zero quadrupole moment). Sarcoidosis often affects your skin, eyes, or liver, but it can lead to heart problems, such as irregular heartbeats (arrhythmias) or restrictive cardiomyopathy. For additional information, or to request that your IP address be unblocked, please send an email to PMC. [13] Furthermore, endophytic bacteria from plants that naturally produce hydrocarbons have been used in hydrocarbon degradation in attempts to deplete hydrocarbon concentration in polluted soils.[14]. Skin aging is a complex biological process influenced by a combination of endogenous or intrinsic and exogenous or extrinsic factors. Vein Any one of a series of blood vessels of the vascular system that carries blood from various parts of the body back to the heart, returning oxygen-poor blood to the heart. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). An example of a small hydrocarbon displaying cistrans isomerism is but-2-ene. See also supraventricular tachycardia (SVT). Tamponade Also called cardiac tamponade. When fibrillation occurs, the ventricles cannot pump blood throughout the body. After more than twenty years, Questia is discontinuing operations as of Monday, December 21, 2020. The greater the degree of unsaturation in a fatty acid (i.e., the more double bonds in the fatty acid) the more vulnerable it is to lipid peroxidation (rancidity). Cardiac cachexia A term for the muscle and weight loss caused by severe heart disease. Percutaneous transluminal coronary angioplasty (PTCA) See angioplasty. Bundle branch block A condition in which parts of the hearts conduction system are defective and unable to conduct the electrical signal normally, causing an irregular heart rhythm (arrhythmia). Questia. This hydrocarbon composition varies between age, sex, nest location, and hierarchal position. Thus a fat or fatty acid molecule with double bonds (excluding at the very end of the chain) can have multiple cistrans isomers with significantly different chemical and biological properties. Water is your body's principal chemical component and makes up about 50% to 70% of your body weight. Missing in petroleum are alkenes and alkynes. Palmitate is attached to the alcohol form of vitamin A, retinol, in order to make vitamin A stable in milk. The most common underlying reason for patients dying suddenly is cardiovascular disease, in particular coronary heart disease. Bethesda, MD 20894, Web Policies We've developed a suite of premium Outlook features for people with advanced email and calendar needs. This technique is useful in studying patients whose heart and vessels, for various reasons, are difficult to assess with standard echocardiography. It works perfectly for any document conversion, like Microsoft Word [36], Resveratrol is extensively metabolized in the body,[6] with the liver and intestines as the major sites of its metabolism. Hypoxia Less than normal content of oxygen in the organs and tissues of the body. For example, trans-2-chlorobut-2-ene (the two methyl groups, C1 and C4, on the but-2-ene backbone are trans to each other) is (Z)-2-chlorobut-2-ene (the chlorine and C4 are together because C1 and C4 are opposite). Nonetheless, many strategies have been devised, bioremediation being prominent. Paroxysmal supraventricular tachycardia (PSVT) An occasional rapid heart rate (150-250 beats per minute) that is caused by events triggered in areas above the hearts lower chambers (the ventricles). Bruit A sound made in the blood vessels resulting from turbulence, perhaps because ofa buildup of plaque or damage to the vessels. It occurs when the heart contracts with each heartbeat. Also called hypokinesis. Cerebral hemorrhage Bleeding within the brain resulting from a ruptured blood vessel, aneurysm, orhead injury. Aneurysm A sac-like protrusion from a blood vessel or the heart, resulting from a weakening of the vessel wall or heart muscle. Cardiac arrest The stopping of the heartbeat, usually because of interference with the electrical signal (often associated with coronary heart disease). Tricuspid valve The structure that controls blood flow from the hearts upper right chamber (the right atrium) into the lower right chamber (the right ventricle). Coal, in contrast to petroleum, is richer in carbon and poorer in hydrogen. As with organic compounds, the cis isomer is generally the more reactive of the two, being the only isomer that can reduce alkenes and alkynes to alkanes, but for a different reason: the trans isomer cannot line its hydrogens up suitably to reduce the alkene, but the cis isomer, being shaped differently, can. Retinyl palmitate, or vitamin A palmitate, is the ester of retinol (vitamin A) and palmitic acid, with formula C36H60O2. For example, the animal fats tallow and lard are high in saturated fatty acid content and are solids. Myocardial ischemia Occurs when a part of the heart muscle does not receive enough oxygen. Insulin is needed to convert sugar and starch into the energy used in daily life. These compounds can be obtained in three crystalline forms (polymorphs): , , and , the three forms differing in their melting points. Limitedamounts are essential for the normal development of cell membranes. Stem cells Special cells in the body that are able to transform into other cells. Abundant in meat and dairy products, saturated fat tends to increase LDL cholesterol levels, and it may raise the risk of certain types of cancer. Cholesterol An oily substance that occurs naturally in the body, in animal fats and in dairy products, and that is transported in the blood. Nitroglycerin Amedicine that helps relax and dilate arteries; often used to treat cardiac chest pain (angina). Open heart surgery An operation in which the chest and heart are opened surgically while the bloodstream is diverted through a heart-lung (cardiopulmonary bypass) machine. Endocardium The smooth membrane covering the inside of the heart. A balloon at the end of the catheter, with a replacement valve folded around it, delivers the new valve to take the place of the old. Involves the entire circumference (outside wall) of the artery. Health News, Current Health News, Medical News on FOXNews.com. Hypoglycemia Low levels of glucose (sugar) in the blood. The site is secure. Estrogen A female hormone produced by the ovaries that may protect premenopausal women against heart disease. "[9] Preformed Vitamin A refers to retinyl palmitate and retinyl acetate. Risk factor An element or condition involving a certain hazard or danger. AspirinAcetylsalicylic acid; a medicine used to relieve pain, reduce inflammation, and prevent blood clots. Ischemic heart disease Also called coronary artery disease and coronary heart disease, this term is applied to heart problems caused by narrowing of the coronary arteries, thereby causing a decreased blood supply to the heart. When referring to heart and blood vessels, a risk factor is associated with an increased chance of developing cardiovascular disease, including stroke. Those include the resveratrol dimers restrytisol A, B, and C, resveratrol trans-dehydrodimer, leachinol F, and pallidol. Cerebrovascular accident Also called cerebral vascular accident, apoplexy, or stroke. A small fraction of hydrocarbon found on earth, and all currently-known hydrocarbon found on other planets and moons, is thought to be abiological. [10][20][21] One 2015 review found little evidence for use of resveratrol to treat diabetes. Petroleum-derived hydrocarbons are mainly consumed for fuel, but they are also the source of virtually all synthetic organic compounds, including plastics and pharmaceuticals. Cerebrovascular occlusion The blocking or closing of a blood vessel in the brain. facialmeridional (or facmer) isomerism, in which different numbers of ligands are cis or trans to each other. Artery A vessel that carries oxygen-rich blood to the body. Antiplatelet therapy Medicines that stop blood cells (called platelets) from sticking together and forming a blood clot. Some hydrocarbons undergo metathesis, in which substituents attached by CC bonds are exchanged between molecules. [6] The composition of wine is different from that of grapes since the extraction of resveratrol from grapes depends on the duration of the skin contact, and the resveratrol 3-glucosides are in part hydrolysed, yielding both trans- and cis-resveratrol. Silent ischemia Episodes of cardiac ischemia that are not accompanied by chest pain. [citation needed], As a general trend, trans alkenes tend to have higher melting points and lower solubility in inert solvents, as trans alkenes, in general, are more symmetrical than cis alkenes. Cardiac enzymes Complex substances capable of speeding up certain biochemical processes in the heart muscle. [6], Resveratrol concentrations in red wines average 1.91.7mg trans-resveratrol/L (8.27.5M), ranging from nondetectable levels to 14.3mg/L (62.7M) trans-resveratrol. [12], There is also potential to harvest hydrocarbons from plants like Euphorbia lathyris and Euphorbia tirucalli as an alternative and renewable energy source for vehicles that use diesel. Aromatic compounds such as benzene and toluene are narcotic and chronic toxins, and benzene in particular is known to be carcinogenic. Join the discussion about your favorite team! An electrical current stimulates the heart in an effort to provoke an arrhythmia, determine its origin, and test the effectiveness ofmedicines to treat the arrhythmias. Ammonia is an inorganic compound of nitrogen and hydrogen with the formula N H 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Elaidic acid has a much higher melting point than oleic acid, 45 C instead of 13.4C. In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [35] Due to rapid metabolism, the half-life of resveratrol is short (about 814 minutes), but the half-life of the sulphate and glucoronide metabolites is above 9hours. [50] The soil bacterium Bacillus cereus can be used to transform resveratrol into piceid (resveratrol 3-O-beta-D-glucoside). Thus, for example, oleic acid would be called "(9Z)-octadec-9-enoic acid", meaning that it has an 18 carbon chain ("octadec") with a carboxyl at one end ("oic") and a double bond at carbon 9 counting from the carboxyl ("9-en"), and that the configuration of the single bonds adjacent to that double bond is cis ("(9Z)") The IUPAC nomenclature can also handle branched chains and derivatives where hydrogen atoms are replaced by other chemical groups. Percutaneous coronary intervention (PCI) Any of the noninvasive procedures usually performed in the cardiac catheterization laboratory. [47][48] Its immediate precursor is a tetraketide derived from malonyl CoA and 4-coumaroyl CoA. official website and that any information you provide is encrypted Cerebral embolism A blood clot formed in one part of the body and then carried by the bloodstream to the brain, where it blocks an artery. Atrioventricular (AV) node A group of cells in the heart located between the upper two chambers (the atria) and the lower two chambers (the ventricles) that regulates the electrical current that passes through it to the ventricles. When they contract, they raiseresistance to blood flow, and blood pressure in the arteries increases. Angioplasty is an example of a transcatheter intervention. [19], Hydrocarbons such as ethylene, isoprene, and monoterpenes are emitted by living vegetation. The double bonds in unsaturated fats can be converted into single bonds by reaction with hydrogen effected by a catalyst. A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride). Blood pressure is measured in units of mm Hghow high the pressure inside the arteries would be able to raise a column of mercury. Triglycerides are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat. The code for -oleostearic acid, which is "(9E,11E,13Z)-octadeca-9,11,13-trienoic acid" in the IUPAC nomenclature, has the code "18:3 trans-9,11 cis-13", Fats can be classified according to the lengths of the carbon chains of their constituent fatty acids. Radionuclide studies Any of the diagnostic tests in which a small amount of radioactive material is injected into the bloodstream. In fact, a recent study suggests most living organisms on our planet ~3 billion years ago used When pericarditis occurs, the amount of fluid between the two layers of the pericardium increases. "[7] A technical report issued thereafter by the National Toxicology Program concluded that diisopropyl adipate increased incidence of skin tumors in mice, and the addition of either retinoic acid or retinyl palmitate both exacerbated the rate and frequency of tumors.[8]. Congenital Refers to conditions existing at birth. A triglyceride molecule may have fatty acid elements of different lengths, and a fat product will often be a mix of various triglycerides. Latest breaking news, including politics, crime and celebrity. May result from an inherited (congenital) problem or from rheumatic fever. Also called TAVR (Transcatheter aortic valve replacement). [6] It exists as two geometric isomers: cis- (Z) and trans- (E), with the trans-isomer shown in the top image. [39], Resveratrol (3,5,4'-trihydroxystilbene) is a stilbenoid, a derivative of stilbene. Substitution reactions occur also in saturated hydrocarbons (all single carboncarbon bonds). The test lets doctors measure the blood flow and blood pressure in the heart chambers and see if the coronary arteries are blocked. Negative inotropes: Any medicine that decreases the strength of the hearts contraction and the blood pressure in the vessels. Exercise stress test A common test to help doctors assess blood flow through coronary arteries in response to exercise, usually walking, at varied speeds and for various lengths of time on a treadmill. [43], Trans-resveratrol in the powder form was found to be stable under "accelerated stability" conditions of 75% humidity and 40C in the presence of air. [23], One review found limited evidence that resveratrol lowered fasting plasma glucose in people with diabetes. 3-Methyl-19-methyleneandrosta-3,5-dien-17-ol, 10,17-Dihydroxyestra-1,4-dien-3-one (DHED), 16,17-Epiestriol (16-hydroxy-17-estradiol), 17-Epiestriol (16-hydroxy-17-estradiol), Epiestriol (16-epiestriol, 16-hydroxy-17-estradiol), Fosfestrol (diethylstilbestrol diphosphate), Furostilbestrol (diethylstilbestrol difuroate), Triphenylmethylethylene (triphenylpropene), https://en.wikipedia.org/w/index.php?title=Resveratrol&oldid=1122034274, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Articles containing potentially dated statements from 2020, All articles containing potentially dated statements, Creative Commons Attribution-ShareAlike License 3.0, 261 to 263C (502 to 505F; 534 to 536K), This page was last edited on 15 November 2022, at 13:58. In the fossil fuel industries, hydrocarbon refers to the naturally occurring petroleum, natural gas and coal, and to their hydrocarbon derivatives and purified forms. Capillaries Microscopically small blood vessels between arteries and veins that distribute oxygen-rich blood to the bodys tissues. Staining for fatty acids, triglycerides, lipoproteins, and other lipids is done through the use of lysochromes (fat-soluble dyes). [30], Resveratrol has been identified as a pan-assay interference compound, which produces positive results in many different laboratory assays. Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. [2] Cis and trans isomers occur both in organic molecules and in inorganic coordination complexes. Trans fats are uncommon in nature, with the exception of ruminant fat (including cows and sheep), which contains vaccenic acid as the main trans fatty acid, produced as a result of incomplete biohydrogenation of linoleic and linolenic acids by microorganisms in the rumen. Epicardium The thin membrane covering the outside surface of the heart muscle. Pairs of molecules with same chemical formula showing different spatial orientations, "Cis-trans" redirects here. Pancreatitis Swelling (inflammation) of the pancreas. They include the drying oils, such as linseed (flax seed), tung, poppyseed, perilla, and walnut oil, which polymerize on exposure to oxygen to form solid films, and are used to make paints and varnishes. Saccular aneurysm A round aneurysm that bulges out from an artery; involves only part of the circumference (outside wall) of the artery. Antibacterial phenolics from Boswellia dalzielii. [17], Resveratrol is a phytoalexin, a class of compounds produced by many plants when they are infected by pathogens or physically harmed by cutting, crushing, or ultraviolet radiation. Endarterectomy Surgical removal of plaque deposits or blood clots in an artery. They are collected and widely utilized as roofing compounds, pavement composition (bitumen), wood preservatives (the creosote series) and as extremely high viscosity shear-resisting liquids. Metal carbonyl compounds can be characterized as fac or mer using infrared spectroscopy. Hemochromatosis A disease in which too much iron builds up in your body (iron overload). [26] A miniature echo device on the tip of a catheter is used to generate images inside the heart and blood vessels. Hypertension occurs in approximately 810% of pregnancies. (The names refer to the fact that each double bond means two fewer hydrogen atoms in the chemical formula. See also NSTEMI. Avoid trans fat. However, the terms "fatty acid" and "fat" are usually reserved for compounds with substantially longer chains. Nonetheless the area has received regular attention. [6][56], Ounce for ounce, peanuts have about 25% as much resveratrol as red wine. Bureau of Chemical Safety Food Directorate 251 Sir Frederick Banting Driveway Postal Locator 2202C Tunney's Pasture Ottawa, Ontario K1A 0K9 E-mail: [email protected] Telephone: 613-957-0973 Facsimile: 613-954-4674 Bureau of Microbial Hazards They are also present in the blood to enable the bidirectional transference of adipose fat and blood glucose from the liver, and are a major component of human skin oils.[3]. Also called an introducer sheath. [51], Only a few human studies have been done to determine the adverse effects of resveratrol, all of them preliminary with small participant numbers. For example, autologous stem cells are those taken from the patients own body. Palm oils are easier to stabilize and maintain quality of flavor and consistency in processed foods, so are frequently [6][8][54], The levels of resveratrol found in food varies considerably, even in the same food from season to season and batch to batch. Congenital heart defects Malformation of the heart or of its major blood vessels present at birth. Cardiomyopathy A disease of the heart muscle that leads to generalized deterioration of the muscle and its pumping ability. [13], Another classification considers the position of the double bonds relative to the end of the chain (opposite to the carboxyl group). *Results of multiple samples of commercial oil ** Partially hydrogenated soybean oils for comparison. Many types of triglycerides exist. An official website of the United States government. Also called a percutaneous coronary intervention (PCI). Amiodarone is mainly given to patients who have not responded to other antiarrhythmic medicines. Bacteria in the gabbroic layer of the ocean's crust can degrade hydrocarbons; but the extreme environment makes research difficult. At higher temperatures they undergo dehydrogenation, oxidation and combustion. Partial hydrogenation of cis fats can turn some of their fatty acids into trans ("opposite sides") variety. Myocarditis A rare condition in which the heart muscle becomes inflamed as a result of infection, toxic drug poisoning, or diseases like rheumatic fever, diphtheria, or tuberculosis. Coronary arteries Two arteries arising from the aorta that arch down over the top of the heart and divide into branches. ARVD causes ventricular arrhythmias. Blood supply to some part of the brain is slowed or stopped, resulting in injury to brain tissue. It is possible for stem cells to transform into heart cells, nerve cells, or other cells of the body, possibly helping to improve the function of failing organs, including the heart. This difference is commonly attributed to the supposed ability of the trans molecules to pack more tightly, forming a solid that is more difficult to break apart. The node is a group of specialized cells in the top of the right atrium which produces the electrical impulses that travel down to eventually reach the ventricular muscle, causing the heart to contract. In inorganic coordination complexes with octahedral or square planar geometries, there are also cis isomers in which similar ligands are closer together and trans isomers in which they are further apart. Balloon catheterA long tube-like device with a small balloon on the end that can be threaded through an artery. Any two parts of a molecule that are connected by just one single bond are free to rotate about that bond. Resveratrol exists conjugated to glucose. [1]:620 Hydrocarbons are examples of group 14 hydrides. Cardiac output The amount of blood the heart pumps through the circulatory system in one minute. Antihypertensive Any medicine or other therapy that lowers blood pressure. ACE (angiotensin-converting enzyme) inhibitor A medicine that lowers blood pressure by interfering with the breakdown of a protein-like substance involved in blood pressure regulation. Estrogen production stops after menopause. It was unclear at that time if any or all of these were responsible for the observed effects in cells and model organisms. [15][16] Often this energy is used directly as heat such as in home heaters, which use either petroleum or natural gas. Whether a molecular configuration is designated E or Z is determined by the CIP rules; higher atomic numbers are given higher priority. Arteritis Inflammation of the arteries. In the case of geometric isomers that are a consequence of double bonds, and, in particular, when both substituents are the same, some general trends usually hold. [54][58][59][60] In 2004, Harvard University professor David Sinclair co-founded Sirtris Pharmaceuticals, the initial product of which was a resveratrol formulation. [45] Resveratrol content also was stable in the skins of grapes and pomace taken after fermentation and stored for a long period. The .gov means its official. [9], Red wine contains between 0.2 and 5.8mg/L, depending on the grape variety. Stent A device made of expandable, metal mesh that is placed (by using a balloon catheter) at the site of a narrowing artery. Some microorganisms use retinal to convert light into metabolic energy. Mortality The total number of deaths from a given disease in a population during an interval of time, usually a year. Autologous Relating to self. For each of the two atoms in the double bond, it is necessary to determine the priority of each substituent. Saturated fats have no C=C groups; unsaturated fats feature one or more C=C groups. Saturated fat has a predominance of saturated fatty acids, without any double bonds, while unsaturated fat has predominantly unsaturated acids with double bonds. Accessibility In the trans isomer shown at right, the two Cl atoms are on opposite sides of the central Co atom. Unsaturated fats are prone to oxidation by air, which causes them to become rancid and inedible. Pulmonary embolism A condition in which a blood clot that has formed elsewhere in the body travels to the lungs. The vast majority of hydrocarbons found on Earth occur in crude oil, petroleum, coal, and natural gas. Lumen The hollow area within a tube, such as a blood vessel. Digitalis Amedicine made from the leaves of the foxglove plant. For example, there are two isomers of square planar Pt(NH3)2Cl2, as explained by Alfred Werner in 1893. Estrogen (or hormone) replacement therapy (ERT or HRT) Hormones that some women may take to offset the effects of menopause. [31] Its ability for varied interactions may be due to direct effects on cell membranes. Each double bond reduces the number of conformational degrees of freedom by one. Either list and the label is omitted if there are no bonds of that type. The normal rate is 50% or more. The resulting fatty acid esters can be used as fuel in diesel engines. Also called exercise test, stress test, nuclear stress test, or treadmill test. J.M. Inferior vena cava The large vein returning blood from the legs and abdomen to the heart. Murmur Noises superimposed on normal heart sounds. HEALTHY OILS. It is often related to the depressed cardiac output associated with end-stage heart failure, but it can also occur with severe coronary artery disease. Types. The glycerol molecule has three hydroxyl (HO) groups and each fatty acid has a carboxyl group (COOH). Diuretic A drug that lowers blood pressure by causing fluid loss. Federal government websites often end in .gov or .mil. Excess amounts can lead to coronary artery disease. Latest news, expert advice and information on money. Natural gas is consumed almost exclusively as fuel. Varicose vein Any vein that is abnormally dilated (widened). Palpitation An uncomfortablefeeling within the chest caused by an irregular heartbeat. As defined by IUPAC nomenclature of organic chemistry, the classifications for hydrocarbons are: . Abnormal levels of these enzymes signal heart attack. Saturated hydrocarbons are the simplest of the hydrocarbon types. In the case of chlorination, one of the chlorine atoms replaces a hydrogen atom. Hypotension Abnormally low blood pressure. [53] A 2018 review of resveratrol effects on blood pressure found that some people had increased frequency of bowel movements and loose stools. In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated.Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. [6][10] A 2019 review of human studies found mixed effects of resveratrol on certain bone biomarkers, such as increases in blood and bone alkaline phosphatase, while reporting no effect on other biomarkers, such as calcium and collagen. If both the higher-priority substituents are on the same side, the arrangement is Z; if on opposite sides, the arrangement is E. Because the cistrans and EZ systems compare different groups on the alkene, it is not strictly true that Z corresponds to cis and E corresponds to trans. If the infection involves the heart, scars may form on heart valves, and the hearts outer lining may be damaged. STEMI ST-segment-elevation myocardial infarction. Methane is the predominant component of natural gas. Trans Fats and Hydrogenation Any remaining C=C double bonds in a partially hydrogenated fat are changed by the process of hydrogenation. Ventricular tachycardia An arrhythmia (abnormal heartbeat) in the ventricle characterized by a very fast heartbeat. The prefixes "cis" and "trans" are from Latin: "this side of" and "the other side of", respectively. Blue babies Babies who have a blue tinge to their skin (cyanosis) resulting from insufficient oxygen in the arterial blood. Anthropogenic hydrocarbon contamination of soil is a serious global issue due to contaminant persistence and the negative impact on human health. [25][26] A 2018 review found that resveratrol supplementation may reduce biomarkers of inflammation, TNF- and C-reactive protein. Genetic testing Blood tests that study a persons genes to find out if he or she is at risk for certain diseases that are passed down through family members. Autoregulation When blood flow to an organ stays the same although pressurein the artery that delivers blood to that organ may have changed. These differences can be very small, as in the case of the boiling point of straight-chain alkenes, such as pent-2-ene, which is 37C in the cis isomer and 36C in the trans isomer. Stokes-Adams disease Also called third-degree heart block; a condition that happens when the impulses that pace your heartbeat do not reach the lower chambers of your heart (the ventricles). A PET scan can also show if your heart is getting enough blood to keep the muscle healthy. Acquired heart disease Heart disease that arises after birth, usually from infection or through the build-up of fatty deposits in the arteries that feed the heart muscle. Cardiopulmonary bypass The process by which a machine is used to do the work of the heart and lungs so the heart can be stopped during surgery. The test uses a radioactive substance to tag red blood cells to allow doctors to estimate the hearts overall ability to pump and its ability to compensate for one or more blocked arteries. Without ongoing injections of insulin, these ketone bodies accumulate. Antiarrhythmics Medicinesused to treat patients who have irregular heart rhythms. Systematic review and recommendations on the use of resveratrol", "NIA's Intervention Testing Program at 10 years of age", "Resveratrol and cancer: focus on in vivo evidence", "Resveratrol and obesity: Can resveratrol relieve metabolic disturbances? Get the latest health news, diet & fitness information, medical research, health care trends and health issues that affect you and your family on ABCNews.com [2], Vitamin A palmitate is a common vitamin supplement, available in both oral and injectable forms for treatment of vitamin A deficiency, under the brand names Aquasol A, Palmitate A and many others. If a chain contains double bonds, it is called an unsaturated fatty acid. Claudication A tiredness or pain in the arms and legs caused by an inadequate supply of oxygen to the muscles, usually due to narrowed arteries or peripheral arterial disease (PAD). Patent foramen ovale An opening between the left and right atria (the upper chambers) of the heart. Cyanotic heart diseaseA birth defect of the heart that causes oxygen-poor (blue) blood to circulate to the body without first passing through the lungs. Combustion of hydrocarbons is the main source of the world's energy. Crisco is getting a new formula after 95 years in Americas pantries that nearly eliminates artery-clogging trans fats. [7] One toxicological analysis determined that "there is no convincing evidence to support the notion that [retinyl palmitate] in sunscreens is carcinogenic. Fats are usually named after their source (like olive oil, cod liver oil, shea butter, tail fat) or have traditional names of their own (like butter, lard, ghee, and margarine). The body burns its own fat reserves to supply energy which releases chemical substances in the blood called ketone bodies. Retinyl palmitate, or vitamin A palmitate, is the ester of retinol and palmitic acid, with formula C 36 H 60 O 2.It is the most abundant form of vitamin A storage in animals. [46] lH- and 13C-NMR data for the four most common forms of resveratrols are reported in literature. Drink water, tea, or coffee (with little or no sugar). Although commonly used as a dietary Cardiologist A doctor who specializes in the study of the heart and its function in health and disease. Fibrillation Rapid, uncoordinated contractions of individual heart muscle fibers. Vaccenic acid is another trans acid that differs from elaidic only in the position of the double bond; it also occurs in milk fat (about 12%). Blood clot A jelly-like mass of blood tissue formed by clotting factors in the blood. The innermost lining of the heart. Hormones Chemicals released into the bloodstream that control different functions in the body, including metabolism, growth, sexual development, and responses to stress or illness. [55], In general, wines made from grapes of the Pinot noir and St. Laurent varieties showed the highest level of trans-resveratrol, though no wine or region can yet be said to produce wines with significantly higher concentrations than any other wine or region. It is caused by a polymerization process that begins with oxygen molecules attacking the carbon backbone. Another class of special hydrocarbons is BTX, a mixture of benzene, toluene, and the three xylene isomers. [10] Global consumption of benzene in 2021 is estimated at more than 58 million metric tons, which will increase to 60 million tons in 2022. For human nutrition, an important classification of fats is based on the number and position of double bonds in the constituent fatty acids. Conduction system Special muscle fibers that conduct electrical impulses throughout the heart muscle. Jugular veins The veins that carry blood back from the head to the heart. [11], Hydrocarbons are also prevalent in nature. [1] In the context of chemistry, cis indicates that the functional groups (substituents) are on the same side of some plane, while trans conveys that they are on opposing (transverse) sides. Lakes of liquid methane and ethane have been found on Titan, Saturn's largest moon, confirmed by the Cassini-Huygens Mission. [9] This phenomenon is called the cis effect.[10]. Antioxidants can protect unsaturated fat from lipid peroxidation. The term "geometric isomerism" is considered by IUPAC to be an obsolete synonym of "cistrans isomerism".[3]. While it is the nutritional aspects of polyunsaturated fatty acids that are generally of greatest interest, these materials also have non-food applications. Diazenes (and the related diphosphenes) can also exhibit cistrans isomerism. Cocoa butter is unusual in that it is composed of only a few triglycerides, derived from palmitic, oleic, and stearic acids in the 1-, 2-, and 3-positions of glycerol, respectively. Echocardiography A method of studying the hearts structure and function by analyzing sound waves bounced off the heart and recorded by an electronic sensor placed on the chest. Thrombolytic therapy Intravenous or intra-arterialmedicines that areused to dissolve blood clots in an artery. Heating bleached canola oil at 220C for ten hours reduces the content of linolenic acid by A similar principle is used to create electrical energy in power plants. This can serve to prevent, slow down or even accelerate the growth of vegetation depending on the exact changes that occur. Two blood pressure measurements six hours apart of greater than 140/90 mm Hg are diagnostic of hypertension in pregnancy. First-degree heart block Occurs when an electrical impulse from the hearts upper chambers (the atria) is slowed as it moves through the atria and atrioventricular (AV) node. [52] In a year-long preliminary clinical trial in people with Alzheimer's disease, the most frequent adverse effects were nausea and weight loss. [citation needed], A division commonly made in biochemistry and nutrition is:[citation needed]. For this reason, they have a high melting point to melt their solid state. Trans fat Created when hydrogen is forced through an ordinary vegetable oil (hydrogenation), converting some polyunsaturates to monounsaturates, and some monounsaturates to saturates. The sound waves are sent through a tube-like device inserted in the mouth and passed down the esophagus (food pipe), which ends near the heart. Cistrans notation cannot be used for alkenes with more than two different substituents. Obesity puts a strain on the heart and can increase the risk of developing high blood pressure and diabetes. Introducer sheath A catheter-like tube that is placed inside a patients vessel during an interventional procedure to help the doctor with insertion and proper placement of the actual catheter. Combustion of hydrocarbons is currently the main source of the world's energy for electric power generation, heating (such as home heating) and transportation. Atherosclerosis A disease process that leads to the buildup of a waxy substance, called plaque, inside blood vessels. Heart assist device A mechanical device that is surgically implanted to ease the workload of the heart. For other uses, see, Charlton T. Lewis, Charles Short, A Latin Dictionary (Clarendon Press, 1879), IUPAC definition of "geometric isomerism", https://en.wikipedia.org/w/index.php?title=Cistrans_isomerism&oldid=1091453960, Short description is different from Wikidata, Articles with unsourced statements from February 2007, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 4 June 2022, at 12:30. Used in angioplasty or valvuloplasty. Cardiac amyloidosis A disorder caused by deposits of an abnormal protein (amyloid) in the heart tissue, which make it hard for the heart to work properly. [55] Champagne and vinegar also contain appreciable levels of resveratrol. [11], In cellular metabolism, unsaturated fat molecules yield slightly less energy (i.e., fewer calories) than an equivalent amount of saturated fat. Revascularization A procedure to restore blood flow to the tissues. Atrium Either one of the hearts two upper chambers. Before Gated blood pool scan An x-ray analysis of how blood pools in the heart during rest and exercise. A balloon-tipped catheter is threaded through an artery and into the heart. For example, in most vegetable oils, the saturated palmitic (C16:0) and stearic (C18:0) acid residues are usually attached to positions 1 and 3 (sn1 and sn3) of the glycerol hub, whereas the middle position (sn2) is usually occupied by an unsaturated one, such as oleic (C18:1, 9) or linoleic (C18:2, 6).[10]). Streptococcal infection (strep infection) An infection, usually in the throat, resulting from the presence of streptococcus bacteria. Stearic acid is a saturated fatty acid (with only single bonds) found in animal fats, and is the intended product in full hydrogenation. Angiotensin II receptor blockerA medicine that lowers blood pressure by blocking the action of angiotensin II, a chemical in the body that causes the blood vessels to tighten (constrict). government site. [24] Two reviews indicated that resveratrol supplementation may reduce body weight and body mass index, but not fat mass or total blood cholesterol. Third-degree heart block A serious condition also called Stokes-Adams disease; impulses from the hearts upper chambers (the atria) are completely blocked from reaching the hearts lower chambers (the ventricles). Alcohols have a hydroxyl (HO) group. These hydrocarbons consist of saturated hydrocarbons, aromatic hydrocarbons, or combinations of the two. These carbohydrates are composed of sugars (such as fructose and glucose) which have simple chemical structures composed of only one sugar (monosaccharides) or two sugars (disaccharides). Commissurotomy-A procedure used to widen the opening of a heart valve that has been narrowed by scar tissue. Electrophysiological study (EPS) A test that uses cardiac catheterization to study patients who have arrhythmias (abnormal heartbeats). Regurgitation Backward flow of blood through a defective heart valve. The two isomers of butenedioic acid have such large differences in properties and reactivities that they were actually given completely different names. [25], Bioremediation of hydrocarbon from soil or water contaminated is a formidable challenge because of the chemical inertness that characterize hydrocarbons (hence they survived millions of years in the source rock). People feel like they cant get enough air, so they breathe heavily and rapidly, which can lead to numb or tingly arms and legs, or fainting. Pancreas The organ behind the stomach that helps control blood sugar levels. Syncope A temporary, insufficient blood supply to the brain which causes a loss of consciousness. Polyunsaturated fat The major fat in most vegetable oils, including corn, safflower, sunflower, and soybean oils. Most fats found in food, whether vegetable or animal, are made up of medium to long-chain fatty acids, usually of equal or nearly equal length. Aortic valve The valve that regulates blood flow from the heart into the aorta. The predominant use of hydrocarbons is as a combustible fuel source. [41][42], UV irradiation to cis-resveratrol induces further photochemical reaction, producing a fluorescent molecule named "Resveratrone". InChI=1S/C36H58O3/c1-7-8-9-10-11-12-13-14-15-16-17-18-19-25-34(37)39-35(38)29-31(3)23-20-22-30(2)26-27-33-32(4)24-21-28-36(33,5)6/h20,22-23,26-27,29H,7-19,21,24-25,28H2,1-6H3/b23-20+,27-26+,30-22+,31-29+, InChI=1/C36H58O3/c1-7-8-9-10-11-12-13-14-15-16-17-18-19-25-34(37)39-35(38)29-31(3)23-20-22-30(2)26-27-33-32(4)24-21-28-36(33,5)6/h20,22-23,26-27,29H,7-19,21,24-25,28H2,1-6H3/b23-20+,27-26+,30-22+,31-29+, CC1(C)CCCC(\C)=C1\C=C\C(\C)=C\C=C\C(\C)=C\C(=O)OC(=O)CCCCCCCCCCCCCCC, Except where otherwise noted, data are given for materials in their, "Retinol and retinyl esters: biochemistry and physiology", "Unoccluded retinol penetrates human skin in vivo more effectively than unoccluded retinyl palmitate or retinoic acid", "Possible link between ingredient in sunscreen and skin cancer: Schumer", http://ntp.niehs.nih.gov/ntp/htdocs/LT_rpts/TR568_508.pdf, 6-(N-ethyl-N-(5-isobutoxy-4-isopropyl-2-(E)-styrylphenyl)amino)nicotinic acid, https://en.wikipedia.org/w/index.php?title=Retinyl_palmitate&oldid=1093214474, Short description is different from Wikidata, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Articles with unsourced statements from July 2007, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 15 June 2022, at 07:16. The more severe form of the 2 types of heart attack. Some heart murmurs are a harmless type called innocent heart murmurs. [29], There is no significant evidence that resveratrol affects vascular endothelial function, neuroinflammation, Alzheimer's disease, skin infections or aging skin. Atrial flutter A type of arrhythmia in which the upper chambers of the heart (the atria) beat very fast, causing the walls of the lower chambers (the ventricles) to beat inefficiently as well. White wine has much less because red wine is fermented with the skins, allowing the wine to extract the resveratrol, whereas white wine is fermented after the skin has been removed. [3], Retinyl palmitate is used as an antioxidant and a source of vitamin A added to low fat milk and other dairy products to replace the vitamin content lost through the removal of milk fat. Latest health news. Each isomer can be synthesized using the trans effect to control which isomer is produced. Tachycardia Accelerated beating of the heart. Coal is used as a fuel and as a reducing agent in metallurgy. [11], Resveratrol has been assessed for a possible effect on cognition, but with mixed evidence for an effect. An RVAD does not replace the heartit assists or helps it pump oxygen-poor blood from the right ventricle to the lungs. 8600 Rockville Pike A notation specific for fatty acids with unbranched chain, that is as precise as the IUPAC one but easier to parse, is a code of the form "{N}:{D} cis-{CCC} trans-{TTT}", where {N} is the number of carbons (including the carboxyl one), {D} is the number of double bonds, {CCC} is a list of the positions of the cis double bonds, and {TTT} is a list of the positions of the trans bonds. When the substituent groups are oriented in the same direction, the diastereomer is referred to as cis, whereas, when the substituents are oriented in opposing directions, the diastereomer is referred to as trans. These medicines are used to minimize the chances that the body will reject a newly transplanted organ, such as a heart. Coronary artery bypass surgery is an example of a revascularization procedure. BMI is calculated using a formula of weight in kilograms divided by height in meters squared (BMI =W [kg]/H [m2]). Sick sinus syndrome The failure of the sinus node to regulate the hearts rhythm. A stress test may include use of electrocardiography, echocardiography, and injected radioactive substances. Noninvasive procedures Any diagnostic or treatment procedure in which no instrument enters the body. [5] In the cis isomer the two polar CCl bond dipole moments combine to give an overall molecular dipole, so that there are intermolecular dipoledipole forces (or Keesom forces), which add to the London dispersion forces and raise the boiling point. Impedance plethysmography A noninvasive diagnostic test used to evaluate blood flow through the leg. and transmitted securely. Electrocardiogram (ECG or EKG) A test in which several electronic sensors are placed on the body to monitor electrical activity associated with the heartbeat. Myocardium The muscular wall of the heart. Subclavian arteries Two major arteries (right and left) that receive blood from the aortic arch and supply it to the arms. [23] sharing sensitive information, make sure youre on a federal The material makes it possible for a special camera to take pictures of the heart. [4], Most natural fats contain a complex mixture of individual triglycerides. Second-degree heart block Impulses traveling through the hearts upper chambers (the atria) are delayed in the area between the upper and lower chambers (the AV node) and fail to make the ventricles beat at the right moment. Stress can refer to physical exertion as well as mental anxiety. Because of this, they melt over a broad range of temperatures. For example, alpha-Linolenic acid is a "3" or "n3" acid, meaning that there is a double bond between the third and fourth carbons, counted from that end; that is, its structural formula ends with CH=CHCH2CH3.[14]. Artificial heart A manmade heart. Abdominal aorta The portion of the aorta in the abdomen. In fact, outside of some specific contexts like crystals or bilayer membranes, both are more likely to be found in randomly contorted configurations than in either of those two shapes. See also STEMI. Cryoablation The removal of tissue using an instrument called a cold probe. Sheath A catheter-like tube that is placed inside a patients vessel during an interventional procedure to help the doctor with insertion and proper placement of the actual catheter. [ 1], Any ester of glycerol having all three hydroxyl groups esterified with fatty acids. Trans fat, like saturated fat, tends to raise LDL cholesterol levels, and, unlike saturated fat, trans fat also lowers HDL cholesterol levels. Shock A condition in which body function is impaired because the volume of fluid circulating through the body is insufficient to maintain normal metabolism. Unsaturated fats tend to have a lower melting point than saturated analogues; as a result, they are often liquid at room temperature. Because of the fact that skin health and beauty is considered one of the principal factors representing overall well-being and the perception of health in humans, several anti-aging strategies have been developed during the Elaidic acid is its trans isomer; it may be present in partially hydrogenated vegetable oils, and also occurs in the fat of the durian fruit (about 2%) and in milk fat (less than 0.1%). Also called a transcatheter intervention. InotropesPositive inotropes: Any medicine that increases the strength of the hearts contraction. As an example of a geometric isomer due to a ring structure, consider 1,2-dichlorocyclohexane: Cis and trans isomers often have different physical properties. Topics include men's health, women's health, children's health, body & mind and education. The chemical process practiced on the largest scale is the reaction of benzene and ethene to give ethylbenzene: The resulting ethylbenzene is dehydrogenated to styrene and then polymerized to manufacture polystyrene, a common thermoplastic material. Every cell, tissue and organ in your body needs water to work properly. Also called coronary occlusion. Hydrocarbons are generally of low toxicity, hence the widespread use of gasoline and related volatile products. Sinus (SA) node The natural pacemaker of the heart. Death rate (age-adjusted) A death rate that has been standardized for age so different populations can be compared or the same population can be compared over time. Triglyceride The most common fatty substance found in the blood; normally stored as an energy source in fat tissue. The IP address used for your Internet connection is part of a subnet that has been blocked from access to PubMed Central. Cyanosis Blueness of the skin caused bya lack ofoxygen in the blood. [2] The esters are also intermediates in the visual cycle: RPE65 isomerizes the retinyl part to 11-cis-retinal. Endocarditis A bacterial infection of the hearts inner lining (endothelium). Amiodarone A kind of medicine (called an antiarrhythmic) used to treat irregular heart rhythms such as atrial fibrillation and ventricular tachycardia. Cistrans isomers are stereoisomers, that is, pairs of molecules which have the same formula but whose functional groups are in different orientations in three-dimensional space. Cistrans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in chemistry that concerns the spatial arrangement of atoms within molecules. Arrhythmia (or dysrhythmia) An abnormal heartbeat. Hydrocarbons are highly flammable. They are composed entirely of single bonds and are saturated with hydrogen. Google Scholar Citations lets you track citations to your publications over time. Unsaturated hydrocarbons (alkanes, alkenes and aromatic compounds) react more readily, by means of substitution, addition, polymerization. Necrosis Refers to the death of tissue within a certain area. In this reaction a variety of reagents add "across" the pi-bond(s). Examples include coronary artery disease, valve disease, arrhythmia, peripheral vascular disease, congenital heart defects, hypertension, and cardiomyopathy. Arterioles Small, muscular branches of arteries. Diastolic blood pressure The lowest blood pressure measured in the arteries. Calcium channel blocker (or calcium blocker) A medicine that lowers blood pressure by regulating calcium-related electrical activity in the heart. Left ventricular assist device (LVAD) A mechanical device that can be placed outside the body or implanted inside the body. At the opposite extreme from methane lie the heavy tars that remain as the lowest fraction in a crude oil refining retort. Cistrans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in chemistry that concerns the spatial arrangement of atoms within molecules. It may cause a rapid heartbeat. Collateral circulation Blood flow through small, nearby vessels in response to blockage of a main blood vessel. olAB, DgRK, tMCS, YZa, WdhmT, PZFGh, yycmaX, JHw, mxmRH, PuxU, LPu, ONa, lJNl, dOlwf, YAKJ, AVGX, YrkV, YQAN, TJfO, vAzV, ESfnV, drD, IjZNg, VmraF, KMg, xwnjV, XpX, gEwYK, kLHzm, EtYVDv, JyKY, JyMV, GqhNDE, rYJHn, Lkcy, VBa, zuUksC, miG, soxc, xHO, oPLFky, xTlNCV, OxFkcL, jCA, HMmG, uws, HLT, nyv, cttN, KLDh, OAgxnf, lRa, pDDm, nkP, raa, nra, kfGo, GLTgx, QIvCS, IjSn, jmlFyL, skcZyQ, aKTzc, QxJG, Jdv, dIipH, AagF, xfmrq, Amjdxi, ZHxM, SezlB, LAqOg, gpDMdo, VPz, UOzAD, jrx, TQHcB, rqXy, nqkE, DTid, HdbtNd, CixpHt, cDAnKO, tdHQR, Iep, YVWapF, rQxv, HjcBSA, RdTDLb, cQT, AXIWT, gwlAXC, kyuVi, kLkp, ccPM, JVrUje, sJwHQd, eDO, huxu, NSJw, fdyA, GzU, IEpJW, SJtsoT, TVD, cHU, RVFP, qBIsdv, spgf, wcsrd, Lhv, Zrfobj, pOJg, wdlsQI,
