Published studies have examined GW501516 in animal models of obesity, insulin resistance, and exercise endurance. Early human trials reportedly ended, and development was discontinued after preclinical findings raised concerns about cancer in some rodent studies. Regulatory agencies have not approved cardarine for any medical use. Its availability through non-pharmaceutical channels raises questions about identity, purity, and legal status that are separate from its laboratory pharmacology. Those questions are often addressed through analytical testing rather than assumptions about product labels.
Cardarine is a common name for GW501516, also GW-1516, a synthetic compound developed as a peroxisome proliferator-activated receptor delta (PPARδ) agonist. It belongs to a class of agents that modulate gene transcription related to lipid and energy metabolism. The compound was studied in preclinical and early clinical research for metabolic and cardiovascular conditions, but it did not progress to approved therapeutic use. Its name appears in fitness and sports contexts despite not being approved as a drug.
Sporting authorities added GW501516 to prohibited lists after it appeared in athlete samples and online markets. The World Anti-Doping Agency classifies it as a hormone and metabolic modulator, and its use can lead to an anti-doping rule violation. Some early laboratory work suggested effects on fatty acid oxidation and endurance-related metabolism in animals, but those findings do not establish safe or effective use in people. Reports of adverse events in humans are scarce and often anecdotal, which complicates risk assessment.
Legal status varies by country. In some places, cardarine is controlled under medicines or psychoactive substances laws; in others, it may be sold with minimal oversight as a research chemical. Customs agencies have intercepted shipments, and several national health agencies have issued warnings about products marketed for bodybuilding or performance enhancement. The lack of a standardized pharmaceutical supply means identity, purity, and contamination levels can differ widely between samples. These factors make cardarine a regulatory and public health concern rather than a conventional prescription drug.
Cardarine is a common name for GW501516, a synthetic compound first described in the 1990s as a selective agonist of the peroxisome proliferator-activated receptor delta. It was studied in preclinical models for metabolic and cardiovascular conditions, but it has not been approved as a medicine in the United States, Europe, or other major jurisdictions. Retail products labeled as cardarine are generally research chemicals or supplements, not pharmaceutical formulations. Because human safety and efficacy data remain limited, regulatory agencies treat it as an unapproved substance rather than a therapeutic product.

Cardarine is frequently described as a fat-burning or endurance-enhancing supplement, but these claims exceed the available evidence. The compound is not a hormone, steroid, or selective androgen receptor modulator. Research articles discuss it as a tool compound for studying PPARδ biology, while anti-doping literature focuses on its abuse and detection. Quality of unapproved products is uncertain, and independent analyses have found impurities or incorrect labeling. Open questions include whether human cancer risk resembles that seen in rodents and how often non-athletes use the substance.
Cardarine has no approved therapeutic indication and is not marketed as a medicine. The World Anti-Doping Agency lists GW501516 as a prohibited substance at all times, covering both in-competition and out-of-competition periods. National laws vary: some countries treat it as an unapproved drug subject to import controls, while others have specific restrictions on sale for human consumption. It is often sold as a research chemical, a label that does not imply safety or legality. Enforcement actions have targeted online vendors and shipments.
Anti-doping laboratories identify GW501516 and its metabolites using liquid chromatography-tandem mass spectrometry. Urine is the usual matrix, and detection can occur after the parent compound has cleared from blood. The exact detection window depends on dose, formulation, individual metabolism, and assay sensitivity. Because the compound is prohibited at all times, athletes are subject to testing in and out of competition. Analytical methods continue to improve as new metabolites and designer analogs are characterized.
GW501516 acts as a ligand for PPAR delta, a nuclear receptor that regulates transcription of genes involved in fatty acid oxidation and energy use. Activation of this receptor in skeletal muscle shifts metabolism toward fat burning in animal models. The compound does not burn fat directly; it changes gene expression over hours to days. Researchers study it to understand metabolic flexibility and exercise adaptation. Effects observed in rodents are not automatically expected in humans.
Safety discussions about cardarine frequently cite rodent carcinogenicity findings reported in the 2000s. In those studies, treated animals developed tumors at multiple sites, leading sponsors to discontinue clinical development. The relevance of these findings to humans has not been resolved, but they are a major reason the compound is not approved. Current literature emphasizes uncertainty about long-term effects and the risks of unregulated use. Regulators and health agencies have not established a safe human exposure level.
Cardarine is a synthetic compound also known as GW501516, GW-501516, and sometimes endurobol. It was developed as a selective agonist of peroxisome proliferator-activated receptor delta, a nuclear receptor involved in fatty acid oxidation and energy metabolism. The compound was studied in preclinical models for metabolic and cardiovascular conditions, but it did not become a marketed human medicine. In regulatory and anti-doping contexts, it is treated as a prohibited substance rather than a licensed medicine.
The pharmacological interest in cardarine centers on PPARδ activation and its downstream effects on lipid handling and mitochondrial function. In animal studies, PPARδ agonists have been associated with changes in exercise endurance and fatty acid utilization, though results vary by model and protocol. Human data remain sparse, and the absence of large controlled trials limits conclusions about efficacy. Researchers often describe the compound as a tool for probing PPARδ biology rather than a proven therapeutic agent.
Gomphrena globosa, commonly known as globe amaranth, is an edible plant from the family Amaranthaceae. The round-shaped flower inflorescences are a visually dominant feature and cultivars have been propagated to exhibit shades of magenta, purple, red, orange, white, pink, and lilac. Within the flowerheads, the true flowers are small and inconspicuous. Gomphrena globosa is native to Central America including regions Panama, and Guatemala, but is now grown globally. As a tropical annual plant, G. globosa blooms continuously throughout summer and early fall. It is very heat tolerant and fairly drought resistant, but grows best in full sun and regular moisture. The plant fixes carbon through the C4 pathway. At maturity, the flowerheads are approximately 4 centimetres (1.6 in) long and the plant grows up to 24 inches (61 cm) in height. Gomphrena globosa is an outcrossing species that is pollinated by butterflies, bees, and other insects. Floral volatiles likely play a significant role in the reproductive success of the plant by promoting the attraction of pollinators.
=== Excretion === Excretion is performed mainly by two small kidneys. In diapsids, uric acid is the main nitrogenous waste product; turtles, like mammals, excrete mainly urea. Unlike the kidneys of mammals and birds, reptile kidneys are unable to produce liquid urine more concentrated than their body fluid. This is because they lack a specialized structure called a loop of Henle, which is present in the nephrons of birds and mammals. Because of this, many reptiles use the colon to aid in the reabsorption of water. Some are also able to take up water stored in the bladder. Excess salts are also excreted by nasal and lingual salt glands in some reptiles. In all reptiles, the urinogenital ducts and the rectum both empty into an organ called a cloaca. In some reptiles, a midventral wall in the cloaca may open into a urinary bladder, but not all. It is present in all turtles and tortoises as well as most lizards, but is lacking in the monitor lizard, the legless lizards. It is absent in the snakes, alligators, and crocodiles. Many turtles and lizards have proportionally very large bladders. Charles Darwin noted that the Galapagos tortoise had a bladder which could store up to 20% of its body weight. Such adaptations are the result of environments such as remote islands and deserts where water is very scarce. Other desert-dwelling reptiles have large bladders that can store a long-term reservoir of water for up to several months and aid in osmoregulation.

Allergy to soy is common, and the food is listed with other foods that commonly cause allergy, such as milk, eggs, peanuts, tree nuts, and shellfish. The problem has been reported among younger children, and the diagnosis of soy allergy is often based on symptoms reported by parents and results of skin tests or blood tests for allergy. Only a few reported studies have attempted to confirm allergy to soy by direct challenge with the food under controlled conditions. It is very difficult to give a reliable estimate of the true prevalence of soy allergy in the general population. To the extent that it does exist, soy allergy may cause cases of urticaria and angioedema, usually within minutes to hours of ingestion. In rare cases, true anaphylaxis may also occur. The reason for the discrepancy is likely that soy proteins, the causative factor in allergy, are far less potent at triggering allergy symptoms than the proteins of peanut and shellfish. An allergy test that is positive demonstrates that the immune system has formed IgE antibodies to soy proteins. However, this is only a factor when soy proteins reach the blood without being digested, in sufficient quantities to reach a threshold to provoke actual symptoms. Soy can also trigger symptoms via food intolerance, a situation where no allergic mechanism can be proven. One scenario is seen in very young infants who have vomiting and diarrhoea when fed soy-based formula, which resolves when the formula is withdrawn.

A lobotomy (from Greek λοβός (lobos) 'lobe' and τομή (tomē) 'cut, slice') or leucotomy is a discredited form of neurosurgical treatment for psychiatric disorder or neurological disorder (e.g. epilepsy, depression) that involves severing connections in the brain's prefrontal cortex. The surgery severs most of the connections to and from the prefrontal cortex, and the anterior part of the frontal lobes of the brain. From the 1930s until the 1970s, the treatment was used for handling psychiatric disorders as a mainstream procedure in some countries. A preoccupation with the ability to work and personal responsibility over patient well-being were contributing factors to the prevalence of lobotomies in the United States. The originator of the procedure, Portuguese neurologist António Egas Moniz, shared the Nobel Prize for Physiology or Medicine of 1949 for the "discovery of the therapeutic value of leucotomy in certain psychoses", although the awarding of the prize has been subject to controversy. The procedure was modified and championed by Walter Freeman, who performed the first lobotomy at a mental hospital in the United States in 1936. Its use increased dramatically from the early 1940s and into the 1950s; by 1951, almost 20,000 lobotomies had been performed in the US and proportionally more in the United Kingdom. More lobotomies were performed on women than on men: a 1951 study found that nearly 60% of American lobotomy patients were women, and limited data shows that 74% of lobotomies in Ontario from 1948 to 1952 were performed on female patients.
==== Superficial vein thrombosis ==== SVT is the development of a thrombus in a superficial vein. SVT is not normally clinically significant, but the thrombus can migrate into the deep venous system where it can also give rise to a pulmonary embolism. The main risk factor for SVT in the lower limbs is varicose veins.
=== Varieties and cultivars === Lotus varieties have been classified according to their use into three types: rhizome lotus, seed lotus, and flower lotus. Varieties that show more than one of these characteristics are classified by the strongest feature. Regarding production area in China, rhizome lotus has the largest area with 200,000 ha (490,000 acres), followed by seed lotus with 20,000 ha (49,000 acres).

== History == Robert Guthrie is given much of the credit for pioneering the earliest screening for phenylketonuria in the late 1960s using a bacterial inhibition assay (BIA) to measure phenylalanine levels in blood samples obtained by pricking a newborn baby's heel on the second day of life on filter paper. Congenital hypothyroidism was the second disease widely added in the 1970s. Guthrie and colleagues also developed bacterial inhibition assays for the detection of maple syrup urine disease and classic galactosemia. The development of tandem mass spectrometry (MS/MS) screening in the early 1990s led to a large expansion of potentially detectable congenital metabolic diseases that can be identified by characteristic patterns of amino acids and acylcarnitines. In many regions, Guthrie's BIA has been replaced by MS/MS profiles, however the filter paper he developed is still used worldwide, and has allowed for the screening of millions of infants around the world each year. In the United States, the American College of Medical Genetics recommended a uniform panel of diseases that all infants born in every state should be screened for. They also developed an evidence-based review process for the addition of conditions in the future. The implementation of this panel across the United States meant all babies born would be screened for the same number of conditions. This recommendation is not binding for individual states, and some states may screen for disorders that are not included on this list of recommended disorders.

=== Pittsburgh Pirates (1960–62) === Mizell's trade to the Pirates was one of the catalysts of Pittsburgh's championship run that season. Facing the Giants on June 16, 1960, he threw 166 pitches and stayed in the ballgame for three hours and two minutes, allowing two runs through eight innings before allowing three hits to start the ninth and getting charged with three more runs, though he still earned the win in the 10–7 victory. "Shucks, no. I wasn't tired," he quipped after the game. On the strength of two shutouts, he pitched 30 consecutive scoreless innings from July 22 to August 9, the longest such streak of his career. The first shutout may have been his best game of the season; he held the Cubs to two hits in a 4–0 victory on July 29. Six days later, he allowed five hits but no runs to the Giants, securing a 1–0 triumph. On September 18, he won another 1–0 game, limiting Cincinnati to three hits in nine innings. In the month of September, he had a 5–1 record and a 3.14 ERA as the Pirates clinched the NL pennant. Mizell went 13-5 for the Pirates that season (14–8 overall) and finished sixth in the NL in winning percentage (.636). Between St. Louis and Pittsburgh, he had a 3.50 ERA (3.12 with the Pirates), striking out 113 and walking 74 in 211 innings. Of the walks, 10 were intentional. Mizell started Game 3 of the 1960 World Series against the New York Yankees but was removed in the first inning, having given up three hits and a walk while only retiring one hitter. He was charged with the loss as the Yankees won 10–0.
Compared with non-parents, parents with children have lower levels of well-being and life satisfaction until children move out of the household, at which point parents have higher well-being and satisfaction. In addition, parents report more feelings of depression and anxiety than non-parents. However, when adults without children are compared to empty nest parents, parenthood is positively associated with emotional well-being. People found parenthood to be more stressful in the 1970s than they did in the 1950s. This is thought to be because of social changes in regards to employment and marital status. Males apparently become less happy after the birth of a child due to added economic pressure and taking on the role of being a parent. A conflict between partners can arise when the couple does not desire traditional roles, or has an increasing number of roles. Unequal responsibilities of child-rearing between men and women account for this difference in satisfaction. Fathers who worked and shared an equal part in child-raising responsibilities were found to be the least satisfied. Research shows that single parents have higher levels of distress and report more mental health problems than married persons. Researchers implemented the Huta & Ryan Scale: Four Eudaimonic Measurement Questionnaire to analyze the participants eudaimonic motives, through motivation towards activities. The investigation was conducted on Canadian university undergraduates. The four eudaimonic pursuits as described by Huta & Ryan are:
Breó (meaning 'glow' in Irish) was a wheat beer; it cost around IR£5 million to develop. A brewing byproduct of Guinness, Guinness Yeast Extract (GYE), was produced until the 1950s. In the UK, a HP Guinness Sauce was manufactured by Heinz and available as of 2013. In March 2010, Guinness began test marketing Guinness Black Lager, a new black lager, in Northern Ireland and Malaysia. As of September 2010, Guinness Black Lager is no longer readily available in Malaysia. In October 2010, Guinness began selling Foreign Extra Stout in 4 packs of bottles in the United States.
