SR9009 is frequently discussed in fitness and research-chemical contexts, yet it has no approved medical indication. Regulatory agencies have not authorized it for human use, and it is not a standard prescription drug. Some sports organizations list it as a prohibited substance because of its potential performance-enhancing properties. Published human data are sparse, so claims about its effects in people often rely on animal models or anecdotal reports. Quality and identity of online materials can vary widely.
SR9009 is a synthetic small molecule studied as a REV-ERB agonist. REV-ERBα and REV-ERBβ are nuclear receptors that help regulate circadian rhythms and metabolic gene expression. The compound was identified in academic screening efforts to find synthetic ligands for these receptors. In cell and animal studies, SR9009 alters transcription of genes involved in lipid and glucose metabolism, and it can shift circadian behavior. It is not an approved therapeutic agent.
Mechanistically, SR9009 binds the ligand-binding domain of REV-ERBα/β and enhances recruitment of corepressor complexes. This represses target genes rather than activating them. Because REV-ERB proteins normally compete with ROR proteins at shared response elements, the net effect depends on tissue and timing. Researchers use SR9009 to probe how nuclear receptor signaling links the clock to metabolism, inflammation, and muscle biology. Findings are largely preclinical, and the precise contribution of each receptor subtype remains under study.
SR9009 is generally described as poorly soluble in water and more soluble in organic solvents such as dimethyl sulfoxide and ethanol. Stock solutions are commonly prepared in an organic solvent before dilution into an aqueous buffer or vehicle. Precipitation can occur if the organic fraction is reduced too quickly or if the final concentration exceeds the compound's solubility limit. Sonication or gentle warming may aid dissolution in some protocols, but excessive heat can promote degradation. Container material and pH can also influence observed solubility.
For long-term storage, SR9009 is typically kept as a solid at low temperature, protected from moisture and light. Desiccated conditions limit hydrolysis, while opaque containers reduce photochemical breakdown. Solutions are less stable than solids and are often stored frozen in aliquots to avoid repeated freeze-thaw cycles. Stability data are not standardized across all suppliers, so users should rely on certificate-of-analysis information when available. Degradation may appear as color change, precipitate, or decreased chromatographic purity.
Laboratory identification of SR9009 typically relies on chromatographic separation coupled to mass spectrometry, often with ultraviolet detection as a secondary check. Nuclear magnetic resonance spectroscopy can confirm molecular structure when a reference standard is available. Because many suppliers sell the compound as a research chemical, independent identity testing is important for experimental reproducibility. A single retention time is not sufficient proof of identity, especially when related compounds may be present. Purity assessments usually report a percentage based on area normalization.

Detection in biological samples can be complicated by rapid metabolism and low circulating concentrations. Some studies report phase I and phase II metabolites, and analytical methods may need to target those species in addition to the parent compound. Immunoassays are not broadly available, so mass spectrometry remains the main confirmatory approach. For anti-doping testing, laboratories look for SR9009 and its metabolites using validated LC-MS methods. Open questions include how long metabolites remain detectable and how different routes of administration alter detection windows.
In laboratory settings, SR9009 is typically characterized by liquid chromatography–mass spectrometry (LC-MS) or high-performance liquid chromatography with ultraviolet detection (HPLC-UV). These methods can confirm identity and estimate purity, but they require reference standards for accurate quantification. Because SR9009 is not a licensed pharmaceutical, no harmonized pharmacopeial monograph exists. Laboratories often validate in-house methods for matrices such as plasma, urine, or cell culture media. Sample preparation may involve protein precipitation or liquid-liquid extraction before analysis.
Because REV-ERB receptors are core clock components, SR9009 has been examined for effects on daily rhythms as well as metabolism. Research has explored whether the compound can shift or reinforce circadian gene expression in tissues such as liver and muscle. Some studies report improved metabolic markers in obese or diabetic mice, while others show context-dependent responses. Questions remain about which effects are direct, which are secondary to timing, and how they might differ across species.
SR9009 is a synthetic small molecule studied as an agonist of REV-ERB nuclear receptors. REV-ERB alpha and REV-ERB beta help regulate circadian rhythms and metabolic gene expression. In laboratory research, SR9009 has been used to probe how these receptors affect skeletal muscle, liver, and adipose tissue. The compound was identified in academic drug-discovery work and is often described in scientific literature by its chemical name and research code. It is not an approved medicine, and human clinical data remain limited or absent.
Laboratory studies often administer SR9009 by injection because oral absorption appears poor in rodents. Reported pharmacokinetic properties include rapid metabolism and low systemic exposure after oral dosing. Human pharmacokinetic data are sparse, so absorption, distribution, metabolism, and excretion in people are not well defined. Some research explores related REV-ERB compounds with improved drug-like properties. Regulatory approval for any REV-ERB agonist as a human medicine has not been granted to date.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ, also called NR1D1 and NR1D2. These receptors help regulate circadian rhythms and metabolic gene programs. The compound was developed for laboratory research, not as an approved therapeutic. Its identity is distinct from steroid hormones and selective androgen receptor modulators. Scientific interest centers on how REV-ERB activation changes gene expression in cells and animal models.
At the molecular level, SR9009 binds the ligand-binding domain of REV-ERB and strengthens recruitment of corepressor proteins such as NCoR and HDAC3. This increases repression of target genes, including Bmal1 and other clock-controlled and metabolic genes. In rodent studies, such changes have been linked to altered lipid handling, glucose metabolism, and energy expenditure. The precise chain of events between receptor binding and whole-body effects remains an active area of research. Findings in animals do not automatically translate to humans.
Identity and purity of SR9009 samples are usually checked with chromatographic and spectrometric methods. High-performance liquid chromatography can separate the compound from related impurities, while mass spectrometry provides molecular mass confirmation. Nuclear magnetic resonance spectroscopy may be used for structural verification in research settings. No single method proves biological activity, and certificates of analysis should be reviewed alongside raw data. Independent testing is often needed because online products vary widely.
SR9009 stability depends on temperature, moisture, light, and solvent. Solid material is generally kept cool and dry, while solutions may require protection from repeated warming and cooling. Degradation can appear as color changes, precipitate, or new chromatographic peaks. Researchers should follow supplier instructions and their own stability data. Long-term storage conditions for human use have not been established because the compound lacks approved clinical formulation.
SR9009 is supplied as a solid research chemical, often in milligram quantities. Laboratories typically weigh it in a controlled environment because fine powders can disperse. Stock solutions are commonly prepared in dimethyl sulfoxide and stored in small aliquots to reduce freeze-thaw cycles. Personal protective equipment and chemical fume hoods are standard when handling unknown or potent compounds. These practices address laboratory safety rather than human use.
In clinical trials, requirements that must be met for an individual to be included in a study. These requirements help make sure that patients in a trial are similar to each other in terms of specific factors such as age, general health, and previous treatment. When all participants meet the same eligibility criteria, it gives researchers greater confidence that results of the study are caused by the intervention being tested and not by other factors.

During an interview for Al Jazeera television on 17 November 2005, he said his election as MP earlier in the year was "despite all the efforts made by the British government, the Zionist movement and the newspapers and news media which are controlled by Zionism". In Trials of the Diaspora: A History of Anti-Semitism in England, Anthony Julius cites this interview as one example of Galloway pandering to the antisemitic prejudices of his audience. According to Julius, Galloway merely refers to the "right-wing press" in the British media, whereas he has the habit of adding the word "Zionist" when speaking on television in the Arab world. A few years later, in a May 2009 speech given at a meeting in Westminster, Galloway said: "I do not agree with the argument that there is a shadowy Jewish influence. Israel is doing what America wants it to do and to argue otherwise is to go down the dark tunnel of racist antisemitism". Galloway criticised the British government's support of Israel during the Gaza war and condemned the genocide of Palestinians in the Gaza Strip. Galloway disputed reports from the Israeli government about the October 7 attacks. Specifically, he disputed the number of babies killed and suggested two-thirds of those killed were from the IDF. He also suggested that those who propagate the official Israeli government account of 7 October are "war criminals". The Board of Deputies of British Jews, the largest Jewish community organisation in the UK, has called Galloway "a demagogue and conspiracy theorist".
Hypnale hypnale is active during early morning and night. It spends the day in leaf litter and thick bushes. This species can be found on the stream side basking during the sunrise. Although it is a slow mover, it is capable of fast strikes. It has an irritable disposition and will vibrate its tail when annoyed, a behavior it has in common with other pit vipers, especially rattlesnakes of the genera Crotalus and Sistrurus. It has been described as nocturnal, terrestrial, and aggressive when disturbed. It is the snake to cause the highest number of recorded snake bites in Sri Lanka.
affected relative pair Any pair of organisms which are related genetically and both affected by the same trait. For example, two cousins who both have blue eyes are an affected relative pair since they are both affected by the allele that codes for blue eyes.

In accordance with the preceding animal and human findings, it has been said that the evidence that the serotonin 5-HT2A receptor mediates the hallucinogenic effects of serotonergic psychedelics is overwhelming. The serotonin 5-HT2A receptor activates several downstream signaling pathways. These include the Gq, β-arrestin2, and other pathways. Activation of both the Gq and β-arrestin2 pathways have been implicated in mediating the hallucinogenic effects of serotonergic psychedelics. However, subsequently, activation of the Gq pathway and not β-arrestin2 has been implicated. Interestingly, Gq signaling appeared to mediate hallucinogenic-like effects, whereas β-arrestin2 mediated receptor downregulation and tachyphylaxis. The lack of psychedelic effects with non-hallucinogenic serotonin 5-HT2A receptor agonists may be due to partial agonism of the serotonin 5-HT2A receptor with efficacy insufficient to produce psychedelic effects or may be due to biased agonism of the serotonin 5-HT2A receptor. There appears to be a threshold level of Gq activation (in terms of intrinsic activity, with EmaxTooltip maximal efficacy >70%) required for production of hallucinogenic effects. Full agonists and partial agonists above this threshold are psychedelic 5-HT2A receptor agonists, whereas partial agonists below this threshold, such as lisuride, 2-bromo-LSD, 6-fluoro-DET, 6-MeO-DMT, and Ariadne, are non-hallucinogenic 5-HT2A receptor agonists.
=== Adrenal glands === The fetal adrenal cortex can be identified within four weeks of gestation. The adrenal cortex originates from the thickening of the intermediate mesoderm. At five to six weeks of gestation, the mesonephros differentiates into a tissue known as the genital ridge. The genital ridge produces the steroidogenic cells for both the gonads and the adrenal cortex. The adrenal medulla is derived from ectodermal cells. Cells that will become adrenal tissue move retroperitoneally to the upper portion of the mesonephros. At seven weeks of gestation, the adrenal cells are joined by sympathetic cells that originate from the neural crest to form the adrenal medulla. At the end of the eighth week, the adrenal glands have been encapsulated and have formed a distinct organ above the developing kidneys. At birth, the adrenal glands weigh approximately eight to nine grams (twice that of the adult adrenal glands) and are 0.5% of the total body weight. At 25 weeks, the adult adrenal cortex zone develops and is responsible for the primary synthesis of steroids during the early postnatal weeks.
Tea and toast syndrome is a form of malnutrition commonly experienced by elderly people who cannot prepare meals and tend to themselves. The term is not intrinsic to tea or bread products only; rather, it describes limited dietary patterns that lead to reduced calories resulting in a deficiency of vitamins and other nutrients. This can contribute to a gradual loss of wellness and muscle due to poor protein intake. In elderly individuals with a low GFR, the syndrome may manifest itself as hyponatremia, a low concentration of the electrolyte sodium in the bloodstream. This is attributed to drinking a large amount of water while consuming a diet poor in salt and protein. Hyponatremia can lead to various neurological problems ranging from headaches and a decreased ability to think, to seizures and coma in the most severe cases.
Austin has said he is "eternally indebted" to Ross for helping his character become popular. On both his podcasts, Austin credited Bret Hart as the wrestler who got him over the most, had most influence on his early wrestling style, and who he had his best matches with. Austin would later go on to induct Bret Hart into the WWE Hall of Fame. The match between Austin and Bret Hart at WrestleMania 13 has been widely regarded as one of the greatest professional wrestling matches of all time, and has been voted by IGN as the greatest match in WrestleMania history, and was number 1 among their list of top 20 WrestleMania matches of all time. The match would later receive the inaugural "Immortal Moment" Award at the 2025 WWE Hall of Fame ceremony. A 12-minute match between Undertaker and Stone Cold Steve Austin drew a 9.5 rating on June 28, 1999. It stands as the highest-rated segment in Raw history. According to the data collected by US-bookies, Stone Cold Steve Austin is still WWE's best merchandise seller earning an estimated $3,600,000 from merchandise on WWE Shop site. John Cena takes the #2 spot, earning almost $2,700,000 from WWE Shop. The 'Austin 3:16' T-shirt is among the best selling T-shirts in wrestling history. In August 2001, Austin began frequently shouting "What?" to interrupt wrestlers who were trying to speak and to initiate fan participation chants.
== R == Rope bridge – Inca rope bridges were suspension bridges made from woven ichu grass, spanning canyons and rivers throughout the Andes. At their peak, at least 200 such bridges connected the Inca road system. Reed boats – a balsa was a boat that was constructed by pre-Columbian South Americans from woven reeds of totora bullrush. These reed boats varied in size from that of a small canoe used for navigation, transportation, and for small-scale fishing to large ships of up to 30 m (98 ft) in length, which were used for war, transportation, bulk goods hauling, and transporting royalty and nobility. They are still used today on Lake Titicaca in Peru and Bolivia by the indigenous peoples living along the banks of the lake. Rubber – the indigenous cultures of Mesoamerica were the first peoples in the world to extract the sap from rubber trees and then use it to make clothes, rubber balls to be played in ceremonial ball games, and many other utilitarian uses. Indigenous peoples, especially those who lived in the Amazon rainforest found many other uses for rubber. The science and technique of extracting sap from rubber trees and then using the sap to make goods made of rubber then spread to the high civilizations of the Andes and elsewhere in the Americas. Rubber balloons – the Olmec were the first people to use rubber balloons. Their civilization arose in 1700 BCE in the Yucatán Peninsula.

== Representation in media == Like many new medical treatments for diseases previously considered incurable, depictions of insulin coma therapy in the media were initially favorable. In the 1940 film Dr. Kildare's Strange Case, young Kildare uses the new "insulin shock cure for schizophrenia" to bring a man back from insanity. The film dramatically shows a five-hour treatment that ends with a patient eating jelly sandwiches and reconnecting with his wife. In the 1943 film I Walked With a Zombie insulin shock therapy is used in an attempt to cure the titular zombie who has been (mis)diagnosed as suffering from catatonia following a "tropical fever". Other films of the era began to show a more sinister approach, beginning with the 1946 film Shock, in which actor Vincent Price plays a doctor who plots to murder a patient using an overdose of insulin in order to keep the fact that he was a murderer a secret. More recent films include Frances (1982) in which actress Frances Farmer undergoes insulin coma treatment, and A Beautiful Mind, which depicted genius John Nash undergoing insulin treatment. In an episode of the medical drama House M.D., House puts himself in an insulin shock to try to make his hallucinations disappear. Sylvia Plath's The Bell Jar refers to insulin coma therapy in chapter 15. In Kelly Rimmer's book, The German Wife, the character Henry Davis undergoes insulin shock therapy to treat 'combat fatigue'.
The pharyngeal jaws of teleosts, a second set of jaws contained within the throat, are composed of five branchial arches, loops of bone which support the gills. The first three arches include a single basibranchial surrounded by two hypobranchials, ceratobranchials, epibranchials and pharyngobranchials. The median basibranchial is covered by a toothplate. The fourth arch is composed of pairs of ceratobranchials and epibranchials, and sometimes additionally, some pharyngobranchials and a basibranchial. The base of the lower pharyngeal jaws is formed by the fifth ceratobranchials while the second, third and fourth pharyngobranchials create the base of the upper. In the more basal teleosts the pharyngeal jaws consist of well-separated thin parts that attach to the neurocranium, pectoral girdle, and hyoid bar. Their function is limited to merely transporting food, and they rely mostly on lower pharyngeal jaw activity. In more derived teleosts the jaws are more powerful, with left and right ceratobranchials fusing to become one lower jaw; the pharyngobranchials fuse to create a large upper jaw that articulates with the neurocranium. They have also developed a muscle that allows the pharyngeal jaws to have a role in grinding food in addition to transporting it. The caudal fin is homocercal, meaning the upper and lower lobes are about equal in size.
== Prognosis == Diabulimia appears to lower life expectancy compared to other patients with type 1 diabetes, with the mean age of death around 45 (13 years lower than that for type 1 diabetes without an eating disorder). This reduced life expectancy is correlated with the severity of eating disorder behaviors.
== Function and mechanism of action == Ghrelin is a participant in regulating the complex process of energy homeostasis which adjusts both energy input – by adjusting hunger signals – and energy output – by adjusting the proportion of energy going to ATP production, fat storage, glycogen storage, and short-term heat loss. The net result of these processes is reflected in body weight, and is under continuous monitoring and adjustment based on metabolic signals and needs. At any given moment in time, it may be in equilibrium or disequilibrium. Gastric-brain communication is an essential part of energy homeostasis, and several communication pathways are probable, including the gastric intracellular mTOR/S6K1 pathway mediating the interaction among ghrelin, nesfatin and endocannabinoid gastric systems, and both afferent and efferent vagal signals. Ghrelin and synthetic ghrelin mimetics (growth hormone secretagogues) increase body weight and fat mass by triggering receptors in the arcuate nucleus that include neuropeptide Y (NPY) and agouti-related protein (AgRP) neurons. Ghrelin-responsiveness of these neurons is both leptin- and insulin-sensitive. Ghrelin reduces the sensitivity of gastric vagal afferents, so they are less sensitive to gastric distension. In addition to its function in energy homeostasis, ghrelin also activates the cholinergic–dopaminergic reward link in inputs to the ventral tegmental area and in the mesolimbic pathway, a circuit that communicates the hedonic and reinforcing aspects of natural rewards, such as food and addictive drugs such as ethanol.
=== Golimumab === Golimumab is a fully human IgG1 monoclonal antibody that was first approved by the FDA in 2009 to treat rheumatoid arthritis. Since, it has been approved to also treat psoriatic arthritis, ankylosing spondylitis, and moderately to severely active ulcerative colitis.
