SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. These receptors help regulate circadian rhythms, lipid metabolism, and inflammatory gene expression. In cell and animal experiments, SR9009 alters transcription of clock-controlled genes and metabolic pathways. The compound is not a hormone and does not resemble classical steroid structures. Its activity depends on binding to the ligand-binding domain of REV-ERB, where it can modify corepressor recruitment.
Research interest in SR9009 grew from studies of circadian biology and metabolic disease. Preclinical reports describe effects on exercise capacity, muscle metabolism, and blood lipid levels in rodents, but these findings come from controlled laboratory settings. The compound has low oral bioavailability in animals, which limits systemic exposure after swallowing. Investigators often use injected routes in experiments to achieve measurable plasma concentrations. Human clinical data are sparse, no approved therapeutic product exists, and whether animal effects translate to humans remains an open question.
Regulatory and sporting contexts treat SR9009 as a prohibited substance in many elite competitions. Its presence on banned lists reflects concerns about performance enhancement and unknown long-term safety. Analytical chemists have developed methods to detect the parent compound and its metabolites in urine and blood. Literature discussions distinguish between in vitro potency, animal pharmacology, and anecdotal human reports. The latter are difficult to verify because products sold online may lack purity or contain different compounds.
Regulatory agencies have not approved SR9009 for human therapeutic use. It is typically sold as a research chemical with labels stating that it is not for human consumption. The World Anti-Doping Agency prohibits the substance in sport, generally under the category of non-approved substances. Customs and national laws may restrict importation, sale, or possession. Product quality and legal status can vary by country and vendor, and therapeutic claims are not permitted in regulated advertising because the compound lacks approval.
Several misconceptions surround SR9009. It is often described as a SARM, a steroid, or an exercise pill, but its known target is the REV-ERB receptor family. Rodent studies have examined exercise capacity and metabolic markers, yet human outcomes remain unproven. Oral bioavailability appears low in animals, and human pharmacokinetics are not well characterized. Online products may contain impurities or different compounds, so identity and purity testing are important for research use.
Analytical chemists detect SR9009 with liquid chromatography-tandem mass spectrometry, commonly abbreviated LC-MS/MS. Sample preparation may involve protein precipitation, liquid-liquid extraction, or solid-phase extraction before analysis. Laboratories can target the parent compound or its metabolites, depending on the matrix and the purpose of testing. Anti-doping methods require sensitive and specific assays because concentrations in biological samples can be low. Reference standards and validated methods are essential for reliable identification and quantification.

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.
Regulatory status varies by country and intended use. Major drug agencies have not granted marketing authorization for SR9009 as a medicine, and it is not listed as a controlled substance in many jurisdictions. It is often sold as a research chemical, a category that may fall outside pharmaceutical manufacturing rules. Buyers should verify local laws and supplier documentation, including certificates of analysis. The lack of standardized quality controls raises concerns about identity, purity, and actual content in products marketed online.
In laboratory settings, SR9009 is commonly identified by its molecular structure and its interaction with REV-ERB receptors. Vendors may list it under synonyms such as Stenabolic or REV-ERB agonist, but those names do not define purity or identity. Analytical confirmation typically uses high-performance liquid chromatography with ultraviolet detection or liquid chromatography–mass spectrometry. A reference standard is needed to compare retention time and mass spectrum, because the compound can be confused with related research chemicals.
Patients present with protrusion of the brain tissue and degeneration of the retina; an individual who has family members with the disorder is at an increased risk of developing it themselves since there is a hereditary link.
Caesium-137, along with other radioactive isotopes caesium-134, iodine-131, xenon-133, and strontium-90, were released into the environment during nearly all atmospheric nuclear weapon tests, and more recently some nuclear accidents, most notably the Chernobyl disaster, the Goiânia Accident and the Fukushima Daiichi disaster. Caesium-137 is produced from the nuclear fission of plutonium and uranium, and by observing the characteristic gamma rays emitted by this isotope, one can determine whether the contents of a given sealed container were made before or after the first atomic bomb explosion (Trinity test, 16 July 1945), which spread some of it into the atmosphere, quickly distributing trace amounts of it around the globe. This procedure has been used by researchers to check the authenticity of certain rare wines, most notably the purported "Jefferson bottles". Surface soils and sediments are also dated by measuring the activity of 137Cs.
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2025, the most expensive non-synthetic element by mass is rhodium, and by volume, iridium. It is followed by rhodium, caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars. While the difficulty of obtaining macroscopic samples of synthetic elements in part explains their high value, there has been interest in converting base metals to gold (chrysopoeia) since ancient times, but only deeper understanding of nuclear physics has allowed the actual production of a tiny amount of gold from other elements for research purposes as demonstrated by Glenn Seaborg. However, both this and other routes of synthesis of precious metals via nuclear reactions is orders of magnitude removed from economic viability. Chlorine, sulfur and carbon (as coal) are cheapest by mass. Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero. For elements whose radiological properties are important, individual isotopes and isomers are listed.
For the idea, that the Germans are the chosen people and have the right to use any and all means to subordinate the "inferior" people, has been expressed over and over again by historians, philosophers, and politicians and finally the Nazis tried to translate it into fact... The best people among the English and Americans wish that the best Germans would understand that there should be a definitive break with this tradition, which has brought the entire world and Germany itself the greatest misfortune. And as a small sign of German understanding the name of the KWS should be changed. What's in a name, if it is a matter of the existence of Germany and thereby Europe? In September 1946, a new Max Planck Society was established at Bad Driburg in the British Zone. On 26 February 1948, after the US and British zones were fused into Bizonia, it was dissolved to make way for the Max Planck Society, with Hahn as the founding president. It took over the 29 institutes of the former Kaiser Wilhelm Society that were located in the British and American zones. When the Federal Republic of Germany (or West-Germany) was formed in 1949, the five institutes located in the French zone joined them. The KWIC, now under Strassmann, built and renovated new accommodation in Mainz, but work proceeded slowly, and it did not relocate from Tailfingen until 1949. Hahn's insistence on retaining Telschow as the general secretary nearly caused a rebellion against his presidency.

Individuals with BPD express higher levels of jealousy towards their partners in romantic relations. Manipulative behavior to obtain nurturance is considered by the DSM-IV-TR and many mental health professionals to be a characteristic of borderline personality disorder. In one research study, 88% of therapists reported that they have experienced manipulation attempts from patient(s). Marsha Linehan has argued that doing so relies upon the assumption that people with BPD who communicate intense pain, or who engage in self-harm and suicidal behavior, do so to influence the behavior of others. The impact of such behavior on others—often an intense emotional reaction in concerned friends, family members, and therapists—is thus assumed to have been the person's intention. According to Linehan, their frequent expressions of intense pain, self-harming, or suicidal behavior may instead represent a method of mood regulation or an escape mechanism from situations that feel unbearable, however, making their assumed manipulative behavior an involuntary and unintentional response.
=== Androgen deficiency === Primary hypogonadism (indicating an intrinsic problem with the testes in males) leads to decreased testosterone synthesis and increased conversion of testosterone to estradiol, potentially leading to a gynecomastic appearance. Klinefelter syndrome is a notable example of a disorder that causes hypogonadism and gynecomastia, and has a higher risk of breast cancer in males (20–50 times higher than males without the disorder). Secondary hypogonadism (indicating a problem with the brain) leads to decreased production and release of luteinizing hormone (LH, a stimulatory signal for endogenous steroid hormone synthesis) which leads to decreased production of testosterone and estradiol in the testes.
== Alveolodental ligament == The main principal fiber group is the alveolodental ligament, which consists of five fiber subgroups: alveolar crest, horizontal, oblique, apical, and interradicular on multirooted teeth. Principal fibers other than the alveolodental ligament are the transseptal fibers. All these fibers help the tooth withstand the naturally substantial compressive forces that occur during chewing and remain embedded in the bone. The ends of the principal fibers that are within either cementum or alveolar bone proper are considered Sharpey fibers.
patent, Preparation of a Whey Protein Concentrate, combined pretreatment and ultrafiltration with water injection and cation exchange to produce a low-mineral, acid-soluble whey protein concentrate suitable for beverage formulations. The water-injection step, or diafiltration, adds water during ultrafiltration so that additional lactose, minerals, and other permeable constituents are removed, while retaining the protein. Diafiltration subsequently became an important method for manufacturing higher-protein whey protein concentrates and whey protein isolates. The New Zealand Dairy Board received a non-exclusive, royalty-free license to use the Coca-Cola process with New Zealand whey. The Dairy Board and NZDRI continued investing in whey-protein processing and product development. The work initiated for Coca-Cola generated deep expertise and provided a technological base for developing whey protein concentrates for other applications and markets. In 1982, the industry established the Whey Products Corporation to coordinate whey processing, investment, and marketing across the cooperative dairy sector. This approach enabled New Zealand to become a leading supplier of technically demanding whey-protein products during the 1980s and 1990s. The industry's centralized whey-products operations were later folded back into the Dairy Board, which merged with Kiwi Co-operative Dairies and New Zealand Dairy Group in 2001 to form Fonterra.
EosFP was first discovered in 2005 during a large scale screen for PAFPs (photoactivatable fluorescent proteins) within the stony coral Lobophyllia hemprichii. It has since been successfully cloned in Escherichia coli and fusion constructs have been developed for use in human cells. Eos was named after the Greek goddess of dawn. Unlike the tetrameric fluorescent proteins derived from anthozoan coral, which can interfere with normal cellular function due to interactions between protein subunits, EosFP has been broken up into dimeric and monomeric variants through the introduction of single point mutations. These variants have been successful in the tracking of cellular components without disturbing function in the host cell and maintain the same photophysical properties as wild-type Eos. Since their discovery, monomeric Eos probes (mEos) have been shown to localize in the cytosol, plasma membrane, endosomes, prevacuolar vesicles, vacuoles, the endoplasmic reticulum, golgi bodies, peroxisomes, mitochondria, invaginations, filamentous actin and cortical microtubules. mEos fusion proteins allow for differential colour labelling in single cells, or groups of cells in developing organs. They can also be used for the understanding of spatial/ temporal interactions between organelles and vesicles. The two fluorescent forms of mEosFP (green and red) are compatible with CFP, GFP, YFP and RFP for multicolour labelling.
