Cardarine is a common name for GW501516, an investigational compound developed in the 1990s for metabolic conditions. 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.
Regulatory treatment varies, but cardarine is not approved as a medicine. Sports authorities list GW501516 as a prohibited substance, and it is banned at all times under the World Anti-Doping Agency code. Many countries restrict sales for human consumption, while online vendors market it as a research chemical. Such products may lack purity data, and their actual contents can differ from the label. Purchasing or possessing cardarine may carry legal consequences depending on jurisdiction. The compound is not a dietary supplement ingredient in regulated markets.
Cardarine is a common name for GW501516, a synthetic compound studied for its effects on lipid and glucose metabolism. It functions as an agonist at peroxisome proliferator-activated receptor delta, or PPARδ, a nuclear receptor that influences gene expression. The molecule is not a steroid, nor is it a selective androgen receptor modulator. It is also known in research and sports literature as GW-501516 and endurobol. Early laboratory work examined its metabolic activity in cell cultures and animal models.
Activation of PPARδ changes transcription of genes involved in fatty acid transport, mitochondrial function, and skeletal muscle fuel preference. In rodent studies, pharmacological PPARδ activation was associated with increased endurance and altered body composition. These findings generated interest in performance enhancement, but species differences and study designs limit direct extrapolation to humans. Small human trials were conducted in the 2000s and later discontinued. The extent to which cardarine produces similar metabolic or performance effects in people remains an open question.

Regulatory treatment of cardarine differs by context and jurisdiction. In competitive sport, the World Anti-Doping Agency lists PPARδ agonists, including GW501516, as prohibited at all times. Outside sport, it lacks approval as a prescription medicine in major drug markets, and products sold for human consumption may be treated as unapproved drugs. Some countries also restrict importation or sale through general consumer protection and medicines laws. These classifications affect availability, testing, and legal risk without establishing therapeutic value.
Because cardarine is not an approved medicine, no pharmacopeial monograph defines its identity, purity, or storage requirements. Laboratories typically rely on in-house methods and reference standards when testing materials labeled as GW501516. Certificates of analysis may report purity and identity for a specific batch, but their scope varies and they do not guarantee safety or legal status. Independent verification can include high-performance liquid chromatography, mass spectrometry, nuclear magnetic resonance, and elemental analysis. The distinction between research chemical labeling and human use is significant because quality standards and oversight differ.
GW501516 acts as an agonist at peroxisome proliferator-activated receptor delta, a nuclear receptor involved in transcription of genes related to lipid handling and energy use. Activation of PPARδ can shift skeletal muscle toward greater fatty acid oxidation in animal models, which is one reason it drew interest for metabolic disease and exercise research. The exact downstream effects depend on tissue, species, dose, and duration. Human data are sparse, so many proposed benefits remain hypotheses rather than established clinical outcomes.
Laboratory studies have examined GW501516 in cell cultures and rodents for conditions such as dyslipidemia, insulin resistance, and obesity. Some trials in humans were initiated, but development was discontinued after preclinical findings raised concerns about cancer in certain models. Those findings do not prove that the compound causes cancer in people, but they contributed to regulatory caution. Later reviews often describe the evidence as preliminary and insufficient for assessing long-term safety.
In the fitness and bodybuilding literature, cardarine is frequently discussed as an endurance agent or fat-loss compound, although such claims are not supported by robust clinical evidence. Online descriptions often mix animal data, user anecdotes, and marketing language. Researchers who study PPARδ agonists distinguish between receptor activation in controlled experiments and unsupervised use of unverified products. The latter introduces unknown purity, dose, and interactions, making reported experiences difficult to interpret scientifically.
== Research == In 2016, work published showing that it can reverse impaired calcium signalling in steatotic liver cells, which, in turn, might be associated with proper glucose control. It is being evaluated for use in the treatment of Parkinson's disease. A phase 3 clinical trial, started in January 2020 has an Estimated Study Completion Date of 30 June 2024 (NCT04232969). A 2025 study in which some Parkinson's patients received exenatide found no evidence that it slowed disease progression or provided any benefit after 96 weeks. The research, in The Lancet, showed no improvements in patient symptoms, brain scans, or any specific subgroup—regardless of how the data was analyzed, the outcome remained unchanged.
The commission noted that "the Russian intervention in Georgia was not limited to a “Blitz”-type action and was not solely focused on rescuing and evacuating Russian citizens." The commission said that "the constitutional obligation to protect Russian nationals [...] cannot serve as a justification for intervention under international law", adding that "Russian domestic law can [...] not be invoked as a justification for a breach of an international law." The commission suggested that "it seems abusive to rely on their need for protection as a reason for intervention, because Russia itself has created this reason for intervention". The commission concluded that "the Russian intervention in Georgia cannot be justified as a rescue operation for Russian nationals in Georgia."
Established in 1889, the University of Cincinnati College of Nursing was the first school to offer a baccalaureate degree in nursing in 1916. In 1942, the college became a charter member of the National League for Nursing. In 2002 the college was the first nursing school to offer cooperative education in addition to clinical time, and in 2010 it began a Doctorate of Nursing Practice. Successes include awarding over $1.0 million in scholarships and graduate assistantship stipends for the 2008 – 2009 academic year, ranking in the top 10 percent of American nursing programs, receiving over $2.6 million in extramural research awards during the 2009 fiscal year and developing partnerships with over 300 clinical sites. In 1982, the college was one of eleven nursing schools that received the Robert Wood Johnson Teaching Nursing Home Project Grant. In 1987, IBM chose the college as one of fifteen to develop computer-assisted interactive video for health sciences. A nursing doctoral program and nurse anesthetist master's program were established in 1990. In 1992, the college established a joint master's degree (MSN/MBA) with the Lindner College of Business.

=== Interleukins and obesity === With the discovery of interleukins (IL), the concept of systemic inflammation developed. Although the processes involved are identical to tissue inflammation, systemic inflammation is not confined to a particular tissue but involves the endothelium and other organ systems. Chronic inflammation is widely observed in obesity. Obese people commonly have many elevated markers of inflammation, including:
In order to avoid the stigma of a restaurant chain, Smashburger crafts local burgers for each city where it is located and markets them extensively. These burgers are designed after consulting with distributors for the kinds of ingredients that are most shipped to a particular city or geographic area. For instance, Smashburger's Colorado locations serve burgers with roasted green chiles, while locations in Miami serve burgers with grilled chorizo. In Minneapolis, the chain has a double-cheese, double-onion variety evoking Scandinavian and Germanic cuisine. Its Oklahoma variety features locally popular fried pickles, while Boston locations serve a burger with onions and a cranberry chutney supplied locally by Ocean Spray. The burgers tend to be original creations as opposed to duplicating local flavors; in the case of Minneapolis the chain deliberately avoided selling a burger that would resemble the locally renowned Jucy Lucy. There are exceptions, such as in Kalamazoo and Grand Rapids restaurants, where the local burger is topped with olives, a tradition that had once been locally popular. The restaurant attracted criticism from health experts for the unhealthiness of some of its menu offerings. A large BBQ Bacon and Cheddar Smashburger has 1,050 calories, while a Chocolate Oreo Shake has 950 calories. Initially, the restaurant made only larger burgers and marketed large servings as a value add, but as it grew it began to offer different sizes to appeal to a larger audience.
A majority of Generation Z live in urban areas and are less inclined to change address than their predecessors. Similar to the Millennials, roughly two thirds of Generation Z come from households of married parents. By contrast, this living arrangement was essentially the norm for Generation X and the Baby Boomers, at 73% and 85%, respectively. As a demographic cohort, Generation Z is smaller than the Baby Boomers or their children, the Millennials. (See population pyramid.) According to the U.S. Census Bureau, Generation Z makes up about one quarter of the U.S. population. This demographic change could have social, cultural, and political implications for the decades ahead. Generation Z are usually the children of Generation X, and sometimes Millennials. Jason Dorsey, who works for the Center of Generational Kinetics, observed that Generation Z is not an extreme version of the Millennials but is rather different, and the differences can largely be attributed to parenting. Like parents from Generation X, members of Generation Z tend to be autonomous and pessimistic. They need validation less than the Millennials and typically become financially literate at an earlier age as many of their parents bore the full brunt of the Great Recession.
