Research interest in SR9009 grew from studies showing improved running endurance in mice after short treatment periods. Those experiments linked the compound to increased mitochondrial content and fatty acid oxidation in muscle, but the findings come from animal models and specific dosing schedules. Independent replication has been limited, and the pathways connecting REV-ERB activation to exercise performance are still being mapped. Whether similar responses occur in humans is an open question.
SR9009 is often grouped with compounds studied for circadian and metabolic regulation rather than with classical anabolic steroids. Its interactions with nuclear receptors differ from those of androgen receptor ligands, and its proposed mechanisms involve transcriptional control rather than direct hormone signaling. Some sources classify it as a metabolic modulator because of observed effects on energy utilization. The distinction matters for regulation and for interpreting research results across different compound classes.
SR9009 is a synthetic small molecule developed as a REV-ERB agonist. It binds to REV-ERBα and REV-ERBβ, nuclear receptors that help regulate circadian rhythms and metabolic gene expression. In cell and animal studies, the compound alters lipid and glucose handling and influences skeletal muscle oxidative capacity. Its exact effects in humans remain largely uncharacterized because controlled clinical trials have not been reported. The molecule is frequently described in preclinical literature as a metabolic modulator.
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.
SR9009 binds REV-ERB receptors and alters their repressive activity on target genes. This action can change transcription of genes involved in lipid handling, glucose metabolism, and mitochondrial function. In rodent studies, treated animals have shown changes in muscle oxidative capacity and exercise performance, though effects vary by dose, duration, and model. The precise molecular steps connecting receptor binding to whole-body outcomes are still an active area of investigation. Findings in animals do not automatically translate to humans.

Stability data for long-term storage are limited, so stock solutions are typically kept cold and used within defined periods. Records of preparation date and concentration support reproducibility.
SR9009 is not approved as a medicine by major regulatory agencies. It is commonly sold as a research chemical, a category that may fall outside customary drug approval and quality rules. In sports, the World Anti-Doping Agency lists SR9009 as a prohibited substance. Athletes who use it can face sanctions if it is detected in a sample. Legal status varies by country, and importation may be restricted. Enforcement practices differ across borders.
He lived out the last ten years of his life addicted to chloral and alcohol, in part to mask the pain of botched surgery to an enlarged testicle in 1877. Oliver Sacks (1933–2015) abused chloral hydrate in 1965 as a depressed insomniac. He found himself taking fifteen times the usual dose of chloral hydrate every night before he eventually ran out, causing violent withdrawal symptoms. Anna Nicole Smith (1967–2007) died of "combined drug intoxication" with chloral hydrate as the "major component". John Tyndall (1820–1893), an Irish physicist, died of an accidental overdose of chloral administered by his wife. Evelyn Waugh (1903–1966), insomniac for much of his adult life, for which "in later life ... he became so deleteriously dependent on chloral". Waugh's novel, The Ordeal of Gilbert Pinfold, is largely a fictionalised account of an episode Waugh himself experienced as a result of excessive use of chloral in combination with bromide and alcohol. Waugh's friend and biographer Christopher Sykes observed that Waugh's description of D. G. Rossetti's demise under the effects of excessive use of chloral in his 1928 biography of the artist "is a fairly exact description of how [Waugh's own] life ended in 1966". Country music singer Hank Williams (1923–1953) died from a combination of chloral hydrate, morphine and whiskey. Renée Vivien (1877-1909), a prominent lesbian poet during the Belle Époque, abused chloral hydrate for much of her life.
=== Chemical === Meitnerium is the seventh member of the 6d series of transition metals, and should be much like the platinum group metals. Calculations on its ionization potentials and atomic and ionic radii are similar to that of its lighter homolog iridium; implying that meitnerium's basic properties will resemble those of the other group 9 elements: cobalt, rhodium, and iridium. Prediction of the chemical properties of meitnerium has not received much attention recently. Meitnerium is expected to be a noble metal. The standard electrode potential for the Mt3+/Mt couple is expected to be 0.8 V. Based on the most stable oxidation states of the lighter group 9 elements, the most stable oxidation states of meitnerium are predicted to be +6, +3, and +1, with the +3 state being the most stable in aqueous solutions. Rhodium and iridium show a maximum oxidation state of +6; the most stable states are +4 and +3 for iridium and +3 for rhodium. The oxidation state +9, represented only by iridium in IrO4+, might be possible for meitnerium nonafluoride MtF9 and the MtO4+ cation, though IrO4+ is expected to be more stable than these meitnerium compounds. The meitnerium tetrahalides have also been predicted to have similar stabilities to those of iridium, thus also allowing a stable +4 state. It is further expected that the maximum oxidation states of elements from bohrium (element 107) to darmstadtium (110) may be stable in the gas phase but not in aqueous solution.
Alongside dame school, Thomas also took private lessons from Gwen James, an elocution teacher who had studied at drama school in London, winning several major prizes. She also taught "Dramatic Art" and "Voice Production", and would often help cast members of the Swansea Little Theatre (see below) with the parts they were playing. Thomas's parents' storytelling and dramatic talents, as well as their theatre-going interests, could also have contributed to the young Thomas's interest in performance. In October 1925, Thomas enrolled at Swansea Grammar School for boys, in Mount Pleasant, where his father taught English. There are several accounts by his teachers and fellow pupils of Thomas's time at grammar school. In June 1928, Thomas won the school's mile race, held at St. Helen's Ground; he carried a newspaper photograph of his victory with him until his death. As a pupil he shied away from the school curriculum, preferring his own choice of reading, drama activities and contributing to the school's magazine of which he became editor. Examples of plagiarised poems he published under his own name in the magazine, and in some cases more widely, have been noted by his biographers. Subsequent research has revealed the extent and virtuosity of Thomas's plagiarism, including having a poem published in the nationally read Boy's Own Paper that had been published in the same magazine 15 years before. During his final school years he began writing his distinctively original poetry in notebooks; the first poem, dated 27 April (1930), is entitled "Osiris, come to Isis".

== History == Brucella canis was first discovered in the United States by Leland Carmichael in 1966, when the bacterium was identified in canine vaginal discharge and the tissues from mass abortions in beagles. B. canis was said to be a biovar of B. suis. With recent research, PCR assay data was able to contradict B. canis and B. suis. PCR data showed a complete difference between the two strains along with B. suis biovars unattained from B. canis DNA. PCR assays have been proven beneficial when differentiating between Brucella strains and vaccine strains. Investigations into the bacterium revealed that domestic dogs are primarily affected along with other canine species. B. canis causes reproductive issues in female dogs, usually in the form of late-term spontaneous abortions. While in males, epididymitis, orchitis, and infertility were observed due to the bacterium. During the 1970s and 1980s, B. canis was reported in North America, Europe, and Asia. The reports were mainly from commercial breeding kennels wherein the bacterium can easily spread. Increase in infections were also attributed to the growing adoption of dogs as pets. By the 2000s, molecular analysis revealed that B. canis is unique from other Brucella species, categorized as a naturally occurring rough species that needs an anti-rough lipopolysaccharide reagent for detection. B. canis has been recognized as a growing zoonotic risk worldwide, having the ability to infect humans. Laboratory exposure or contact with pet dogs that had aborted fetuses were the main sources of exposure to the bacterium.

=== Biosecurity and bioterrorism === Some ethical issues relate to biosecurity, where biosynthetic technologies could be deliberately used to cause harm to society and/or the environment. Since synthetic biology raises ethical issues and biosecurity issues, humanity must consider and plan on how to deal with potentially harmful creations, and what kinds of ethical measures could possibly be employed to deter nefarious biosynthetic technologies. With the exception of regulating synthetic biology and biotechnology companies, however, the issues are not seen as new because they were raised during the earlier recombinant DNA and genetically modified organism (GMO) debates, and extensive regulations of genetic engineering and pathogen research are already in place in many jurisdictions. Additionally, the development of synthetic biology tools has made it easier for individuals with less education, training, and access to equipment to modify and use pathogenic organisms as bioweapons. This increases the threat of bioterrorism, especially as terrorist groups become aware of the significant social, economic, and political disruption caused by pandemics like COVID-19. As new techniques are developed in the field of synthetic biology, the risk of bioterrorism is likely to continue to grow.
