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.
PPARδ is a nuclear receptor that influences transcription of genes involved in fatty acid oxidation, lipid transport, and energy homeostasis. GW501516 binds and activates this receptor with high selectivity relative to PPARα and PPARγ in laboratory assays. Activation alters expression of target genes in skeletal muscle, liver, and adipose tissue in animal models. The exact clinical consequences of these changes in humans remain incompletely characterized, and observed effects in animals do not establish therapeutic benefit or safety.
At the molecular level, GW501516 binds and activates PPARδ, a nuclear receptor that regulates transcription. Activation shifts expression of genes involved in fatty acid oxidation, energy expenditure, and lipid transport in skeletal muscle and liver. Animal studies report increased endurance and altered lipid profiles after exposure. Human data are limited to small trials and do not establish long-term safety or efficacy. PPARδ also has roles in cell proliferation, so the relationship between activation and cancer risk remains an open question.
Published literature on cardarine includes in vitro assays, rodent experiments, and a small number of human studies. Reports describe effects on exercise capacity and lipid metabolism in animals, while human evidence is sparse. Many online descriptions present the compound as a proven endurance aid, a claim not supported by regulatory approval or large clinical trials. Analytical studies focus on identifying the parent compound and its metabolites in biological samples. Important uncertainties include species differences, dose-response relationships, and the relevance of rodent tumor findings to humans.

In laboratory settings, cardarine is studied as a tool compound for probing PPARδ biology. Published experiments often use cell cultures, rodent models, or isolated tissues. Some investigations focus on metabolic effects, while others assess potential risks such as carcinogenicity observed in long-term animal studies. Because human trials are sparse, most knowledge comes from preclinical work and adverse event reports. Scientific literature frequently notes the gap between animal findings and human outcomes. The compound is not a dietary supplement and is not intended for human consumption.
Cardarine is a common name for GW501516, a synthetic compound developed in the 1990s through research collaborations involving GlaxoSmithKline. It belongs to a class of molecules known as peroxisome proliferator-activated receptor delta agonists. Early studies explored its effects on lipid metabolism and energy expenditure in animal models. The compound was never approved as a human medicine, and clinical development was discontinued. In the years since, it has appeared in fitness and bodybuilding communities as a performance-enhancing substance. Regulatory agencies classify it as an unapproved drug.
PPARδ is a nuclear receptor that regulates gene expression related to fatty acid oxidation, glucose homeostasis, and mitochondrial function. GW501516 binds to this receptor with high affinity and activates downstream signaling in skeletal muscle and other tissues. Animal studies reported increased endurance and altered fuel preference, but human data remain limited and inconsistent. The precise relationship between receptor activation and observed physiological changes is still an area of active investigation. Researchers have also examined whether the compound affects inflammation or cell proliferation. No approved therapeutic indication exists for cardarine.
Clinical development stopped after rodent studies showed tumors at multiple sites. Whether those findings predict human cancer risk remains an open question, but they led sponsors to discontinue programs. Human safety data are limited to small, short-term studies that were not designed to assess cancer risk. Reported effects in those studies included changes in blood lipids, but the evidence is insufficient for medical use. Long-term consequences of nonmedical use are not well characterized. Questions about dose, duration, and individual susceptibility remain unresolved.

It acts as an agonist at peroxisome proliferator-activated receptor delta, a nuclear receptor involved in lipid and energy metabolism. The compound is frequently mislabeled as a selective androgen receptor modulator, or SARM, but its molecular target is different. GW501516 reached early clinical testing before development was discontinued. It has no approved therapeutic use in any country. The name cardarine is not a formal international nonproprietary name.
In the early 2000s, White Castle tried expanding into the Kansas City market, with at least one location in Kansas, but those restaurants were closed several years later. In April 2020, White Castle responded to the COVID-19 pandemic by announcing that the chain would be delivering free meals to healthcare workers. White Castle also offered a free dessert in the month of May 2021 to anyone who showed a vaccination certificate. In certain regions, White Castle offered four hours of paid time off for workers who get both doses of an eligible COVID-19 vaccination and present their vaccination certificate to management.
The escalation in the price of oil in 1974 increased the cost of the Western world's energy tenfold. In response, the U.S. government promoted the production of gasohol, gasoline with 10 percent alcohol added, as an answer to the energy crisis. In 1979, when the Soviet Union sent troops to Afghanistan, the Carter administration cut off its supplies to agricultural produce in retaliation, creating a surplus of agriculture in the U.S. As a result, fermenting the agricultural surpluses to synthesize fuel seemed to be an economical solution to the shortage of oil threatened by the Iran–Iraq War. Before the new direction could be taken, however, the political wind changed again: the Reagan administration came to power in January 1981 and, with the declining oil prices of the 1980s, ended support for the gasohol industry before it was born. Biotechnology seemed to be the solution for major social problems, including world hunger and energy crises. In the 1960s, radical measures would be needed to meet world starvation, and biotechnology seemed to provide an answer. However, the solutions proved to be too expensive and socially unacceptable, and solving world hunger through SCP food was dismissed. In the 1970s, the food crisis was succeeded by the energy crisis, and here too, biotechnology seemed to provide an answer. But once again, costs proved prohibitive as oil prices slumped in the 1980s. Thus, in practice, the implications of biotechnology were not fully realized in these situations. But this would soon change with the rise of genetic engineering.
There are numerous theories as to the exact cause and mechanism in type 2 diabetes. Central obesity is known to predispose individuals for insulin resistance. Abdominal fat is especially active hormonally, secreting a group of hormones called adipokines that may possibly impair glucose tolerance. But adiponectin, an anti-inflammatory adipokine, which is found in lower concentration in obese and diabetic individuals has shown to be beneficial and protective in type 2 diabetes mellitus (T2DM). Insulin resistance is a major feature of diabetes mellitus type 2, and central obesity is correlated with both insulin resistance and T2DM itself. Increased adiposity (obesity) raises serum resistin levels, which in turn directly correlate to insulin resistance. Studies have also confirmed a direct correlation between resistin levels and T2DM. And it is waistline adipose tissue (central obesity) which seems to be the foremost type of fat deposits contributing to rising levels of serum resistin. Conversely, serum resistin levels have been found to decline with decreased adiposity following medical treatment.
Counter-Strike: Source retains its team-based objective-oriented first-person shooter style gameplay. The aim of playing a map is to accomplish a map's objective: defusing the bomb, rescuing all hostages, or killing the entire opposing team. The ultimate goal of the game is to win more rounds than the opposing team. Once players are killed, they do not respawn until the next round, though this depends on which server people play on. This gameplay feature distinguishes Counter-Strike from other first-person shooter games, where players respawn instantly or after a short delay. Shooting while moving dramatically decreases accuracy, and holding the trigger down to continuously shoot produces severe recoil. The severity of damage induced by weaponry is dependent upon the specific locations of hits, with hits to the head being most lethal and shots which make contact elsewhere causing lesser loss of health. Damage is also affected by the distance, and if the target wears protection.

=== South Ossetia === The Government of South Ossetia in Tskhinvali called for Russian help to prevent "genocide" when the Georgian bombardment began, saying that Tskhinvali was under "the most frightful fire".
Traumatic acid is a monounsaturated dicarboxylic acid that occurs naturally in plants. The compound was first isolated from wounded bean plants by American chemists James English Jr. and James Frederick Bonner and Dutch scientist Arie Jan Haagen-Smit in 1939. Traumatic acid is a potent wound healing agent in plants ("wound hormone") that stimulates cell division near a trauma site to form a protective callus and to heal the damaged tissue. It may also act as a growth hormone, especially in inferior plants (e.g. algae). Traumatic acid is biosynthesized in plants by non-enzymatic oxidation of traumatin (12-oxo-trans-10-dodecenoic acid), another wound hormone. Traumatic acid, was among the first biologically active molecules isolated from plant tissues. This dicarboxylic acid was shown to be a potent wound healing agent in plant that stimulates cell division near a wound site, it derives from 18:2 or 18:3 fatty acid hydroperoxides after conversion into oxo- fatty acids. At normal conditions, traumatic acid is a solid, crystalline, water-insoluble substance. The salts and esters of traumatic acid are called traumatates. Traumatic acid is used as an intermediate in prostaglandin synthesis. It is also a constituent of some pharmaceutical products, such as the odontostomatologic gel Restomyl, due to its mucosal re-epithelialization activity.
=== Infectious dose === The infectious dose is the amount of agent that must be consumed to give rise to symptoms of foodborne illness, and varies according to the agent and the consumer's age and overall health. Pathogens vary in minimum infectious dose; for example, Shigella sonnei has a low estimated minimum dose of < 500 colony-forming units (CFU) while Staphylococcus aureus has a relatively high estimate. Importantly, prior exposure to pathogens can significantly increase an individual's tolerance to subsequent exposures. Locals in a region may tolerate pathogen levels that would cause illness in travelers due to immune memory developed from repeated low-level exposures. This helps explain why locals often consume food without illness that might sicken visitors. In the case of Salmonella a relatively large inoculum of 1 million to 1 billion organisms is necessary to produce symptoms in healthy human volunteers, as Salmonellae are very sensitive to acid. An unusually high stomach pH level (low acidity) greatly reduces the number of bacteria required to cause symptoms by a factor of between 10 and 100.
=== Transition zone: a changing microstructure === As solidification slows and growth kinetics become rate-limiting, the ice crystals begin to exclude the particles, redistributing them within the suspension. A competitive growth process develops between two crystal populations, those with their basal planes aligned with the thermal gradient (z-crystals) and those that are randomly oriented (r-crystals) giving rise to the start of the TZ. There are colonies of similarly aligned ice crystals growing throughout the suspension. There are fine lamellae of aligned z-crystals growing with their basal planes aligned with the thermal gradient. The r-crystals appear in this cross-section as platelets but in actuality, they are most similar to columnar dendritic crystals cut along a bias. Within the transition zone, the r-crystals either stop growing or turn into z-crystals that eventually become the predominant orientation, and lead to steady-state growth. There are some reasons why this occurs. For one, during freezing, the growing crystals tend to align with the temperature gradient, as this is the lowest energy configuration and thermodynamically preferential. Aligned growth, however, can mean two different things. Assuming the temperature gradient is vertical, the growing crystal will either be parallel (z-crystal) or perpendicular (r-crystal) to this gradient. A crystal that lays horizontally can still grow in line with the temperature gradient, but it will mean growing on its face rather than its edge.
Insulin therapy can be injection under the skin multiple times a day, or can be delivered continuously as a basal amount with boluses for high blood sugar or before meals using an insulin pump. A diabetic diet, exercise, and lifestyle modifications are considered cornerstones of management. If left untreated, type 1 diabetes results in death. Type 1 diabetes can cause many complications if blood sugar control is not very well controlled. Complications of relatively rapid onset include diabetic ketoacidosis and nonketotic hyperosmolar coma. Long-term complications include heart disease, stroke, kidney failure (Diabetic Nephropathy), foot ulcers, and damage to the eyes (diabetic retinopathy). As insulin lowers blood sugar levels, complications may arise from low blood sugar if more insulin is taken than necessary. Type 1 diabetes makes up an estimated 5–10% of all diabetes cases. The number of people affected globally is unknown, although it is estimated that about 80,000 children develop the disease each year. Within the United States the number of people affected is estimated to be one to three million. Rates of disease vary widely, with approximately one new case per 100,000 per year in East Asia and Latin America and around 30 new cases per 100,000 per year in Scandinavia and Kuwait. It typically begins in children and young adults but can begin at any age.

==== Burial ==== As the human population progresses, cultures and traditions change with it. Evolution is generally slow, sometimes more rapid. South Korea's funeral arrangements have drastically changed in the course of only two decades according to Chang-Won Park. Around the 1980s at home funeral ceremonies were the general norm, straying away from anywhere that was not a family home. Dying close to home, with friends and family, was considered a 'good death', while dying away from home was considered a 'bad death'. This gradually changed as the upper and middle class started holding funerals in the mortuaries of hospitals. This posed an issue for hospitals because of the rapid increase in funerals being held and maxing occupancy. This quickly resolved when a law was passed to allow the civilian population holding funerals in the mortuaries of hospitals. The lower class quickly followed suit, copying the newly set traditions of the upper classes. With this change, cremation also practice more as an alternative to traditional burials. Cremation was first introduced by Buddhism, and was quickly banned in 1470. It was not until the Japanese colonization period that cremation was reintroduced in 1945 and later on lifted the ban. It took until 1998 for cremation to rapidly grow in popularity.
== Adverse effects == Dutasteride has overall been found to be well tolerated in studies of both men and women, producing minimal side effects. Adverse effects include headache and gastrointestinal discomfort. Isolated reports of menstrual changes, acne, and dizziness also exist. A small risk of sexual side effects has been documented in men taking the drug during the first few months of therapy. The FDA added a black-box warning to dutasteride in 2011 describing an increased risk of high-grade prostate cancer in those who take the drug. No direct mechanistic link between 5α-reductase inhibitors and prostate cancer has been established. This is not due to a direct link between dutasteride or other 5α-reductase inhibitors and cancer per se, but rather that those who take 5α-reductase inhibitors may have a decrease in prostate-specific antigen (PSA) levels, and therefore increases in PSA (which are an indicator of possible cancer) may be masked in those who take the drug. This is thought to delay cancer diagnosis so that patients taking 5α-reductase inhibitors present with a higher-grade tumor at the time of diagnosis. The American Urological Association advises that increased risk for patients taking these drugs leads to higher prostate cancer-specific and all-cause mortality. The AUA also advises that this effect can be alleviated with more frequent screening and lower PSA cutoffs for diagnostic biopsies in men taking dutasteride or other 5α-reductase inhibitors. Dutasteride is known to reduce the growth and prevalence of benign prostate tumors.
About six months after the United States invasion of Iraq of 2003, rumors of Iraq prison abuse scandals started to emerge. Many of the abuse incidents that emerged occurred at Abu Ghraib prison. Graphic pictures of some of those abuse incidents were made public. Less well-known abuse incidents have been documented at American prisons throughout Iraq.
Blood transfusion is the process of transferring blood products into a person's circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, plasma, platelets, and other clotting factors. White blood cells are transfused only in very rare circumstances, since granulocyte transfusion has limited applications. Whole blood has come back into use in the trauma setting. Red blood cells (RBC) contain hemoglobin and supply the cells of the body with oxygen. White blood cells are not commonly used during transfusions, but they are part of the immune system and also fight infections. Plasma is the "yellowish" liquid part of blood, which acts as a buffer and contains proteins and other important substances needed for the body's overall health. Platelets are involved in blood clotting, preventing the body from bleeding. Before these components were known, doctors believed that blood was homogeneous. Because of this scientific misunderstanding, many patients died because of incompatible blood transferred to them.
chromosome condensation The process by which eukaryotic chromosomes become shorter, thicker, denser, and more conspicuous under a microscope during prophase due to systemic coiling and supercoiling of chromatic strands of DNA in preparation for cell division.
