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.
Safety concerns emerged from long-term animal studies. In rodents given the compound for extended periods, researchers found an increased incidence of certain cancers, including liver and bladder tumors. These findings contributed to the discontinuation of clinical development. Whether similar risks apply to short-term or low-level exposure in humans is not established, and controlled human safety data are limited. The relevance of high-dose rodent carcinogenicity findings to human use remains a subject of debate.
Human trials of GW501516 were small and short in duration. They examined lipid levels, glucose handling, and other metabolic markers, but the programs were halted after the animal cancer findings. No approved therapeutic product exists, and published human data are insufficient for establishing long-term safety. Reports of use for athletic performance come mainly from non-clinical settings and cannot be verified through controlled trials. Independent testing of products sold as cardarine has found inconsistent purity and labeling.

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.
Preclinical research reported that GW501516 increased running endurance in mice and improved lipid profiles in some animal species. Early human trials explored effects on high-density lipoprotein cholesterol, triglycerides, and glucose handling, but the program was discontinued. Published human data are sparse and do not establish efficacy for any condition. Studies also examined PPAR delta in cancer biology, with conflicting findings across models. The relationship between receptor activation, tissue context, and disease risk remains an active area of investigation.
A common misconception is that cardarine has been proven safe for human use. In reality, human clinical data are limited, and long-term animal studies have raised concerns about cancer. Another misconception is that it is a supplement or vitamin-like compound. It is a synthetic research chemical with no approved medical indication. Scientific discussion often focuses on its mechanism and detection rather than therapeutic use. Regulatory and anti-doping literature treats it primarily as a prohibited substance.
Cardarine is explicitly prohibited by the World Anti-Doping Agency under the class of PPARδ agonists. Its presence in urine or blood samples can be detected using mass spectrometry-based methods, often liquid chromatography-tandem mass spectrometry. Athletes who test positive may face sanctions, including bans from competition. The compound is also regulated as a prescription-only or unapproved drug in many countries. Enforcement varies by jurisdiction, and some regions treat it as a controlled substance. Online sales may occur despite these restrictions, creating quality and legal risks.

=== Pain === The weak opioid codeine, in low doses and combined with one or more other drugs, is available in prescription medicines and, in some jurisdictions, without a prescription to treat mild pain. Other opioids are usually reserved for the relief of moderate to severe pain.
== Medical uses == Cipaglucosidase alfa is a long-term enzyme replacement therapy used in combination with the enzyme stabilizer miglustat for the treatment of adults with late-onset Pompe disease (acid α-glucosidase [GAA] deficiency).
Peitzmeier and colleagues conducted a study on partner violence; they found that transgender individuals are 3 times more likely than their counterparts to experience partner violence physical and sexual. Partner violence is a risk factor for numerous health outcomes like a decrease psychological well-being, a poor sexual health, etc. There is limited data regarding the impact of social determinants of health on transgender and gender non-conforming individuals' health outcomes. However, despite the limited data available, transgender and gender non-conforming individuals have been found to be at higher risk of experiencing poor health outcomes and restricted access to health care due to increased risk for violence, isolation, and other types of discrimination both inside and outside the health care setting. Despite its importance, access to preventive care is also limited by several factors, including discrimination and erasure. A study on young transgender women's access to HIV treatment found that one of the main contributors to not accessing care was the use of incorrect name and pronouns. A meta analysis of the National Transgender Discrimination Survey examined respondents who used the "gender not listed here" option on the survey and their experiences with accessing health care. Over a third of the people who chose that option said that they had avoided accessing general care due to bias and fears of social repercussions.

The Bentley compounds are a class of semi-synthetic opioids that were first synthesized by K. W. Bentley by Diels-Alder reaction of thebaine with various dienophiles. The compounds are also known as thevinols, orvinols, or bridged oripavine derivatives, due to the characteristic 6,14-endo-ethano- or etheno-bridge and substitution at the 7α position. Buprenorphine and etorphine are perhaps the best known of the family, which was the first series of extremely potent μ-opioid agonists, with some compounds in the series having over many thousands of times the analgesic potency of morphine.
== Organisation == NCCD is overseen by a Governing Council and an Executive Committee, with equal representation of public and private sectors, chaired by the Secretary (A&C, Ministry of Agriculture). The principal executive of this body was originally conceived as its Director who would implement the decisions of the Executive Body. The first Director of NCCD was Mr. Sanjeev Chopra, a Joint Secretary in the Ministry of Agriculture. However, in keeping with the technical domain requirements, the governing bodies initially decided to invite an established leader from the private sector as a chief advisor to assist in incubating the body and develop a roadmap. In this initial stage, various concept level revisions were proposed regarding cold chain and the requirements to make it future ready. In these years, India's horticultural production also overtook that in food grains. Subsequently, in 2014 the Governing Council decided that this body required to be strengthened with relevant domain expertise. It restructured the organization and added the position of Chief Executive Officer, to be filled by an industry stalwart with hands-on domain experience. The government officer nominated Director, was thereafter to provide administration support, with the professional Chief Executive Officer responsible to provide executive and technical direction. Capt. Pawanexh Kohli was the first Chief Advisor and the founding Chief Executive Officer of NCCD and headed this organization for its first eight years from 2012 to 2020.
=== Parasocial contact hypothesis === The parasocial contact hypothesis posits that positive portrayals of minority groups in media help to reduce stigmas and stereotypes surrounding these groups. Applying this theory to the portrayal of mental illnesses, if media represents well-rounded, accurate characters who are experiencing mental illness, it can challenge the long-standing stereotypes and work to reduce the stigma surrounding mental health. Furthermore, when in-groups and out-groups engage in positive contact, there is the possibility of challenging stereotypes and prejudice.
The white shark is difficult to keep in captivity due to its large size and migratory nature. Attempts have been made since 1955 in facilities in North America, Hawaii, Australia, and South Africa. The sharks survived only for days during the earliest attempts, while in the early 1980s, aquariums like Steinhart Aquarium, Sea World San Diego, and Marineland of the Pacific were able to keep juvenile white sharks for weeks before releasing them. A major contributor to the mortality of captive white sharks was the stress of poor transport; many were accidentally captured by commercial nets and kept on fishing lines or in a tank before being handed over to aquarium staff. One famous shark named Sandy, who measured 2.3 m (7.5 ft), was kept at Steinhart for five days in August 1980 and was released after bumping into the walls. The most successful exhibitions occurred at Monterey Bay Aquarium (MBA), which displayed six white sharks between 2004 and 2011. Researchers at universities in California attributed this success to a 4-million-US-gallon (15,000,000 L) net pen, which gave the sharks time to recover from capture before being moved. Additionally, a 3,200-US-gallon (12,000 L) portable tank allowed the sharks to swim continuously during transit. Although the sharks were 1.4–1.6 m (4.6–5.2 ft) at the start of their stay, they eventually outgrew the exhibit and required release. One shark was kept for 198 days and attracted one million visitors. Having gathered sufficient data on the species, MBA discontinued the program in 2011.
This process is run thousands or millions of times. The number of times a single tree is visited during the course of the chain is an approximation of its posterior probability. Some of the most common algorithms used in MCMC methods include the Metropolis–Hastings algorithms, the Metropolis-Coupling MCMC (MC³) and the LOCAL algorithm of Larget and Simon.

In Japan in 675, the Emperor Tenmu prohibited the killing and the eating of meat during the busy farming period between April and September but excluded the eating of wild birds and wild animals. These bans and several others that followed over the centuries were overturned in the nineteenth century during the Meiji Restoration. In China, during the Song dynasty, Buddhist cuisine became popular enough that vegetarian restaurants appeared where chefs used ingredients such as beans, gluten, root vegetables and mushrooms to create meat analogues including pork, fowl, eggs and crab roe and many meat substitutes used even today such as tofu, seitan and konjac originate in Chinese Buddhist cuisine.
Panera Bread Company ( pə-NAIR-ə) is an American multinational chain of bakery-cafe fast casual restaurants with over 2,000 locations, all of which are in the United States and Canada. Its headquarters are in Fenton, Missouri. The chain operates as Saint Louis Bread Company in the Greater St. Louis area, with over 100 locations. Panera offers a wide array of pastries and baked goods, such as bagels, brownies, cookies, croissants, muffins, and scones. These, along with Panera's artisan breads, are typically baked by an on-staff baker the day before serving. Aside from the bakery section, Panera has a regular menu for dine-in or takeout, including salads, sandwiches, side choices, and soups, as well as coffee, espresso drinks, frozen drinks, fruit smoothies, hot chocolate, iced drinks, lattes, lemonade, and tea. Panera Bread, formerly owned by Au Bon Pain, is currently owned by JAB Holding Company, which is, in turn, owned by the Reimann family of Germany. Panera was once the largest provider of free Wi-Fi hotspots in the United States.
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.
It is the usual line used in the United States to determine treatment of acetaminophen overdose after the publication of the NAC study in 1981. With early NAC and supportive therapy, the majority of patients recover with no adverse effects. Of patients that progress to acute liver failure, 65% of patients will recover; the remainder will either require liver transplantation or die.
== Contraindications == Zopiclone causes impaired driving skills similar to those of benzodiazepines. Long-term users of hypnotic drugs for sleep disorders develop only partial tolerance to adverse effects on driving, with users of hypnotic drugs even after one year of use still showing an increased motor vehicle accident rate. Patients who drive motor vehicles should not take zopiclone as there is a significantly increased risk of accidents in zopiclone users. Zopiclone induces impairment of psychomotor function. Driving or operating machinery should be avoided after taking zopiclone as effects can carry over to the next day, including impaired hand-eye coordination. A double-blind study on the effect on performance of several hypnotic medications, relevant to military personnel who may have to be awakened to carry out duties, found that drugs listed in increasing order of performance impact duration were melatonin (with no impact), zaleplon, temazepam, and zopiclone. The effects on serial reaction time (SRT), logical reasoning (LRT), serial subtraction (SST), and multitask (MT) were measured. For zaleplon (10 mg), zopiclone (7.5 mg) and temazepam (15 mg) respectively the times to recover normal performance for SRT were 3.25, 6.25, and 5.25 hours; for LRT 3.25, >6.25, and 4.25 hours; for SST 2.25, >6.25, and 4.25 hours; and for MT 2.25, 4.25, and 3.25 hours. The study did not consider the effectiveness of the drugs on sleep.

Cardarine is commonly known as GW501516 or GW-1516. These names refer to the same synthetic compound. It is not a brand-name approved medicine.
No, cardarine is not a steroid. It is classified as a PPARδ agonist. Its structure and receptor target differ from anabolic steroids.
No regulatory agency has approved cardarine as a medicine. It was investigated in early research but development was discontinued. It is not available as a prescription drug.
Rodent studies reported increased endurance and fat oxidation after GW501516 exposure. Long-term studies also found higher rates of some tumors, which led to halted development.
