Everything below concerns WADA Prohibited List. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-09-03. Where a claim depends on a specific study, the study is described rather than over-claimed.
A persistent misconception is that cardarine is a fat-burning drug or a safe alternative to anabolic steroids. No approved therapeutic product exists, and human safety data are limited. The tumor findings in rodents remain a central concern in scientific reviews. Products sold online may contain inaccurate labels, impurities, or different compounds entirely, which complicates any assessment of effects. Independent testing of such products has reported frequent mislabeling. For these reasons, discussions in the literature emphasize risks and unknowns rather than benefits.
Cardarine is not approved for human therapeutic use in any major jurisdiction. It appears on the World Anti-Doping Agency Prohibited List as a PPARδ agonist within the hormone and metabolic modulators category. Sports organizations test for it because it has been detected in athlete samples and seized products. Regulatory actions against marketed research chemical versions have occurred in several countries, though enforcement varies. Availability through unregulated channels complicates oversight.
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.
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.

Cardarine is the common name for GW501516, a synthetic compound studied as a peroxisome proliferator-activated receptor delta agonist. Researchers developed it to explore treatments for lipid disorders and metabolic conditions. It is not an approved medicine in any country. Early clinical work examined changes in HDL cholesterol and triglycerides, but development was discontinued after animal studies raised concerns about cancer. The compound remains available as a research chemical and appears in discussions of performance enhancement.
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.
Anti-doping laboratories identify GW501516 and related metabolites using liquid chromatography coupled with tandem mass spectrometry. Urine is the most common matrix, though blood and dried blood spots may also be analyzed. The method targets the parent compound and phase I and phase II metabolites, which extend the detection window. Because the substance is prohibited at all times, athletes can be tested outside competition. Detection limits and windows depend on the assay, sample type, and individual metabolism.
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.
Laboratory studies indicate that GW501516 activates PPARδ, a nuclear receptor involved in fatty acid oxidation and energy metabolism. In rodent experiments, treated animals often showed increased endurance and reduced fat mass. These effects were observed under controlled conditions and do not establish safe or effective use in humans. The exact dose-response relationship in humans remains poorly characterized. Species differences in metabolism can affect how results translate across animals and people.
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.
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.
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.
== Third ministry == On 20 June 1972, following the 1972 election on 27 May, the Ministry was reconstituted by the Governor, Sir Colin Hannah, and served until the next reconstitution of the ministry on 23 December 1974. John Row retired from Parliament, and a further cabinet vacancy existed due to Delamothe's departure in December 1971. Keith Hooper and Henry McKechnie were appointed to fill the vacancies.
== Gochujang hot-taste unit == Gochujang hot-taste unit (GHU) is a unit of measurement for the pungency (spicy heat) of gochujang, based on the gas chromatography and the high-performance liquid chromatography of capsaicin and dihydrocapsaicin concentrations. Gochujang products are assigned to one of the five levels of spiciness: Mild, Slight Hot, Medium Hot, Very Hot, and Extreme Hot.
== Signs and symptoms == LNS is characterized by three major hallmarks: neurologic dysfunction, cognitive and behavioral disturbances including self-mutilation, and uric acid overproduction (hyperuricemia). Damage to the basal ganglia causes affected individuals to adopt a characteristic fencing stance due to the nature of the lesion. Some may also have macrocytic anemia due to the faulty DNA synthesis, most likely due to deficient purine synthesis that leads to a lag of cell division with respect to increases in cell mass. Virtually all patients are male; males experience delayed growth and puberty, and most develop shrunken testicles or testicular atrophy. Female carriers are at an increased risk for gouty arthritis but are usually otherwise unaffected.
Catholic socialism was promoted by politicians such as Heinrich Mertens and Vitus Heller, as well as the Catholic priest Wilhelm Hohoff, who argued that Marx's criticism of capitalism is consistent with Catholic social teaching, and believed that the atheism of socialism "was not an essential ingredient but only a transient phase". The Catholic socialists of the Centre Party presented various positions, such as promoting a "third way" between capitalism and communism based on the papal encyclical Quadragesimo anno, or advocating economical socialism with a strongly religious and socially conservative character, but rejecting the secular currents of socialism and social democracy. In stark contrast to pro-parliamentary and pro-republican factions of the Centre, there were also anti-republican and anti-democratic factions, which argued that Weimar democracy promoted anti-Catholic values such as secularism, individualism and materialism. The party's right wing was represented by figures such as the cardinal Michael von Faulhaber or Hermann Port, who sought cooperation with conservative parties. Because of the extreme ideological heterogeneity of the party, it simultaneously participated in pro- and anti-republican coalitions on the local level. In attempt to solve internal dissent, the party would increasingly appoint Catholic priests and clerics to leading positions, as opposed to non-clerical politicians associated with certain interest groups within the party. This practice led to the appointment of figures such as Ludwig Kaas in 1928.

==== Bacterial ==== Studies have shown that bacterial infections of the human urinary tract, vagina (i.e., bacterial vaginosis), gums (i.e., periodontitis), and abscesses in various tissues are associated with high concentrations of SCFAs, especially acetic acid, at the infection sites or, in urinary tract infections, the urine. These SCFAs may be made and released by the bacteria and/or host cells in the infected areas. Several studies have suggested that SCFAs act through FFAR2 to suppress these infections. 1) Compared to control mice, Ffar2 gene knockout mice had more severe infections in models of Citrobacter rodentium, Klebsiella pneumoniae, Clostridioides difficile, and Streptococcus pneumoniae bacterial infections. 2) Injection of acetic acid into the peritoneum 1/2 hour before or 6 hours after injection of Staphylococcus aureus bacteria into the bloodstream of mice reduced signs of severe disease, the amount of body weight lost, and the numbers of bacteria recovered from the liver, spleen, and kidneys; these reductions did not occur in Fffar2 gene knockdown mice. And, 3) higher circulating blood cell levels of FFAR2 messenger RNA were associated with higher survival rates in patients with sepsis, i.e., disseminated bacterial infections, compared to patients with lower levels of blood cell FFAR2 messenger RNA. These studies suggest that FFAR2 reduces the severity of the cited bacterial infections in humans and mice and recommend further studies on the roles of FFAR2 in these and other bacterial infections.
Nanotechnology has been accepted as a tool for many industrial and domestic fields like gas monitoring systems, fire and toxic gas detectors, ventilation control, breath alcohol detectors and many more. Other sources state that nanotechnology has the potential to develop the pollutants sensing and detection methods that already exist. The ability to detect pollutants and sense unwanted materials will be heightened by the large surface area of nanomaterials and their high surface energy. The World Health Organization declared in 2014 that air contamination caused around 7 million deaths in 2012. This new technology could be an essential asset to this epidemic. The three ways that nanotechnology is being used to treat air pollution are nano-adsorptive materials, degradation by nanocatalysis, and filtration/separation by nanofilters. Nanoscale adsorbents being the main alleviator for many air pollution difficulties. Their structure permits a great interaction with organic compounds as well as increased selectivity and stability in maximum adsorption capacity. Other advantages include high electrical and thermal conductivities, high strength, high hardness. Target pollutants that can be targeted by nanomolecules are 〖NO〗_x, 〖CO〗_2, 〖NH〗_3, N_2, VOCs, Isopropyl vapor, 〖CH〗_3 OH gases, N_2 O, H_2 S. Carbon nanotubes specifically remove particles in many ways. One method is by passing them through the nanotubes where the molecules are oxidized; the molecules then are adsorbed on a nitrate species.
== History == The first low-cost spectrophotometer capable of recording an infrared spectrum was the Perkin-Elmer Infracord produced in 1957. This instrument covered the wavelength range from 2.5 μm to 15 μm (wavenumber range 4,000 cm−1 to 660 cm−1). The lower wavelength limit was chosen to encompass the highest known vibration frequency due to a fundamental molecular vibration. The upper limit was imposed by the fact that the dispersing element was a prism made from a single crystal of rock-salt (sodium chloride), which becomes opaque at wavelengths longer than about 15 μm; this spectral region became known as the rock-salt region. Later instruments used potassium bromide prisms to extend the range to 25 μm (400 cm−1) and caesium iodide 50 μm (200 cm−1). The region beyond 50 μm (200 cm−1) became known as the far-infrared region; at very long wavelengths it merges into the microwave region. Measurements in the far infrared needed the development of accurately ruled diffraction gratings to replace the prisms as dispersing elements, since salt crystals are opaque in this region. More sensitive detectors than the bolometer were required because of the low energy of the radiation. One such was the Golay detector. An additional issue is the need to exclude atmospheric water vapour because water vapour has an intense pure rotational spectrum in this region. Far-infrared spectrophotometers were cumbersome, slow and expensive.

== Biosimilar insulin == A biosimilar is a biological medicine that is highly similar to an already approved reference biologic in terms of structure, biological activity, efficacy, and safety. These medicines are large, complex molecules produced through biotechnology in living systems, such as microorganisms, plant cells, or animal cells. Due to differences in the manufacturing process, biosimilars cannot be exact copies of reference biologics but must demonstrate high similarity through extensive structural and functional analysis. Manufacturers are required to show that a biosimilar has no clinically meaningful differences from its reference product regarding safety, purity, and potency, which is assessed through pharmacokinetic (PK) and pharmacodynamic (PD) studies, immunogenicity evaluations, and, if necessary, additional clinical studies. Biosimilars can only be developed and marketed once the patent on the original reference biologic has expired, allowing for competition and increased availability of biologic therapies. The expiration of patents for first-generation insulin analogs has facilitated the development of biosimilar insulins, offering potential to improve global insulin access. Despite the essential role of insulin, approximately half of individuals who require it do not have access due to high costs and limited availability. This issue is particularly pronounced in low-income countries, where economic factors can restrict the use of biologic treatments such as insulin.
In November 2008, the Department of State said that finding the culprit was less important than "to get both sides, particularly the Russians, to live up to their obligations". On 9 September 2008, Chair of the House Foreign Affairs Committee Howard Berman stated in hearing of the United States House Committee on Foreign Affairs that Russia had been provoking Georgia and Saakashvili was compelled to respond to an ethnic cleansing of Georgians in South Ossetia. Berman continued that Russian actions revealed that Russia's real aim was not protection of the Russian citizens. On 9 September 2008, Assistant Secretary of State for European and Eurasian Affairs Daniel Fried said in hearing of the House Committee on Foreign Affairs that Russia had been provoking Georgia and Russia's actual aim was to change the borders of the sovereign nation. Fried further described the events on the night of August 7 and reported that the Georgians had reported the entry of the Russian forces into the Roki Tunnel. Fried said that the US administration clearly "pointed out that use of military force [by Georgia], even in the face of provocations, would lead to a disaster." Fried stated that "one fact is clear—there was no justification for Russia's invasion of Georgia." When Fried was asked why Georgian leadership ignored his clear advice not to resort to military force, he replied that Georgia "had been provoked for a long period of time" by the opposing sides.
White sharks are estimated to reach over 70 years of age. A 2018 study of sharks off eastern Australia and New Zealand found that juveniles had an annual survival rate of over 70%, while adults exceeded 90%. White sharks are sometimes preyed on by orcas, with which they also likely compete for food. The first recorded orca predation occurred at the Farallon Islands in 1997 when an estimated 4.7–5.3 m (15–17 ft) female orca killed an estimated 3–4 m (10–13 ft) white shark. Another similar attack apparently occurred there in 2000, but its outcome is not clear. Orca predation has since been documented on white sharks in other areas. Around South Africa, orcas typically hunt white sharks in groups of two to six. By flipping the sharks belly up, the whales trigger a paralytic state known as tonic immobility, allowing them to precisely target and consume the sharks' energy-rich livers. In 2017, a live white shark was sighted with purported orca teeth marks, providing the first evidence of the species surviving such an attack. White sharks often evacuate an area when orcas arrive, as has been documented both off South Africa and California. However, a 2026 study near Neptune Islands concluded that orcas alone are unlikely to cause white sharks to leave an area long-term. In addition to orcas, white sharks may fall prey to other sharks, including older white sharks, as pups and juveniles.
An intermediate bulk container (IBC, IBC Tote, IBC Tank) is a multi-use container employed for the general transport, storage, and handling of bulk fluids and materials. IBC tanks are compatible with, and resistant to, an extensive list of chemicals, acids, caustics, as well as inert materials and food grade consumables. IBCs are commonly manufactured from the following materials:

No. Cardarine has not received approval for human therapeutic use in major jurisdictions. It remains an investigational compound.
It is classified as a PPARδ agonist on the WADA Prohibited List. Anti-doping laboratories can detect it and its metabolites in urine. Its use is banned in competition and usually out of competition.
Rodent studies reported increased tumor incidence at multiple sites. The human relevance remains uncertain, but the findings contributed to discontinuation of development. No long-term human cancer data are available.
It binds to and activates PPAR delta, a nuclear receptor that controls expression of genes related to fatty acid oxidation. This mechanism can alter energy metabolism in animal models. It is not a direct stimulant or fat-burning enzyme.
