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.
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.

Laboratory samples of SR9009 are typically handled as research chemicals rather than pharmaceuticals. Suppliers usually state that the material is for research use only and not for human or veterinary administration. Storage recommendations generally call for a freezer at approximately −20 °C, protection from light, and a desiccated environment. The solid is often described as a white to off-white powder. Solubility is commonly reported in organic solvents such as dimethyl sulfoxide and ethanol, with low solubility in water.
Analytical identification and purity assessment often use high-performance liquid chromatography with ultraviolet detection or mass spectrometry. Liquid chromatography–tandem mass spectrometry is used to detect and quantify SR9009 in biological matrices, including urine and blood, for anti-doping or pharmacokinetic studies. Nuclear magnetic resonance spectroscopy can confirm molecular structure. Stability depends on form and storage: the solid is generally more stable than solutions, and repeated freeze–thaw cycles may degrade samples. Purity is typically reported as a percentage from a certificate of analysis.
Regulatory treatment of SR9009 varies by country and context. It is not approved as a therapeutic drug by agencies such as the United States Food and Drug Administration or the European Medicines Agency. Sports authorities list it as a prohibited substance; the World Anti-Doping Agency classifies it among hormone and metabolic modulators. Legal status for personal possession or sale differs across jurisdictions, and some countries may restrict it under analog or research chemical laws. Buyers who seek verified material often rely on independent laboratory testing because online product labels may not match contents.
REV-ERB proteins typically suppress gene expression by recruiting corepressor complexes to DNA response elements. SR9009 binds these receptors and strengthens that repressive action in cell-based assays. Studies in rodents have reported changes in lipid handling, mitochondrial function, and exercise capacity after treatment. Such findings are often cited as evidence for metabolic effects, but species differences and limited pharmacokinetic data make direct translation to humans uncertain. Researchers continue to examine which effects are robust and which depend on specific experimental conditions.
SR9009 is frequently discussed alongside other REV-ERB ligands, including synthetic agonists and natural heme-related molecules. Its selectivity for REV-ERB over related nuclear receptors has been measured in binding and reporter assays, though off-target activity at higher concentrations is possible. The compound is prohibited in sport by the World Anti-Doping Agency, and it is not approved for any medical use in major jurisdictions. Products sold online may be labeled as research chemicals, and their identity and purity are not guaranteed by regulatory review.
SR9009 is a synthetic small molecule that acts on the nuclear receptors REV-ERBα and REV-ERBβ. These receptors are part of the circadian clock machinery and normally repress transcription of certain target genes. In laboratory research, SR9009 is used as a chemical tool to study how REV-ERB activity influences metabolism, inflammation, and daily biological rhythms. The compound is not an approved medicine, and its effects in humans remain largely uncharacterized. It is often described as an investigational agent rather than a therapeutic product.
===== Forms ===== LSD is produced in crystalline form and is then mixed with excipients or redissolved for production in ingestible forms. Liquid solution is either distributed in small vials or, more commonly, sprayed onto or soaked into a distribution medium. Historically, LSD solutions were first sold on sugar cubes, but practical considerations forced a change to tablet form. Appearing in 1968 as an orange tablet measuring about 6 mm across, "Orange Sunshine" acid was the first largely available form of LSD after its possession was made illegal. Tim Scully, a prominent chemist, made some of these tablets, but said that most "Sunshine" in the USA came by way of Ronald Stark, who imported approximately thirty-five million doses from Europe. Over some time, tablet dimensions, weight, shape and concentration of LSD evolved from large (4.5–8.1 mm diameter), heavyweight (≥150 μg), round, high concentration (90–350 μg/tab) dose units to small (2.0–3.5 mm diameter) lightweight (as low as 4.7 μg/tab), variously shaped, lower concentration (12–85 μg/tab, average range 30–40 μg/tab) dose units. LSD tablet shapes have included cylinders, cones, stars, spacecraft, and heart shapes. The smallest tablets became known as "Microdots". After tablets came "computer acid" or "blotter paper LSD", typically made by dipping a preprinted sheet of blotting paper into an LSD/water/alcohol solution. More than 200 types of LSD tablets have been encountered since 1969, and more than 350 blotter paper designs have been observed since 1975.
=== Other cancers === Study of S. Hallum shows association between male origin fetal cells and ovarian cancer risk. Presence of Y chromosome was used to detect foreign cells in women's blood. Microchimerism is a result of pregnancy, possibility that foreign cells were of transfusion or transplantation origin was rejected due to women's health. Women testing positive for male origin microchimerism cells had reduced hazard rates of ovarian cancer than women testing negative. Pregnancy at older ages can reduce risk of ovarian cancer. Numbers of microchimeric cells declines after pregnancy, and ovarian cancer is most frequent in postmenopausal women. This suggests that fetal microchimerism may play a protective role in ovarian cancer as well. Microchimeric cells also cluster several times more in lung tumors than in surrounding healthy lung tissue. Fetal cells from the bone marrow go to the tumor sites where they may have tissue repair functions. Microchimerism of fetomaternal cell trafficking origin might be associated with the pathogenesis or progression of cervical cancer. Male cells were observed in patients with cervical cancer but not in positive controls. Microchimeric cells might induce the alteration of the woman's immune system and make the cervical tissue more susceptible to HPV infection or provide a suitable environment for tumor growth.
==== Allowed in some states, banned in others ==== The governments of some states, particularly Congress-ruled states, have said they will allow foreign supermarkets to open in their state. Andhra Pradesh, Assam, Delhi, Haryana, Kashmir, Maharashtra, Manipur, Uttarakhand, Daman & Diu and Dadra and Nagar Haveli, will allow foreign retailers. Other states have said they will not allow foreign supermarkets to open in their state. These include West Bengal, Gujarat, Bihar, Kerala, Madhya Pradesh, Tripura, and Orissa, and Rajasthan. Supporters of retail reform who have voiced the need to promote organised retail include Chief Ministers of several states of India, several belonging to political parties that have no affiliation with Congress-led central government of India. The list includes the Chief Ministers of Maharashtra, Andhra Pradesh, Tamil Nadu and Gujarat. In a report submitted earlier in 2011, these Chief Ministers urged the Prime Minister to prioritize reforms to help promote organised retail, shorten the retail path from farm to consumer, allow organised retail to buy direct from farmers at remunerative produce prices, and reduce farm to retail costs. Similarly, the Chief Minister of Delhi has come out in support of the retail reform, as have the Chief Ministers of the two farming states of Haryana and Punjab in north India., The Chief Ministers of Haryana and Punjab claim that the announced retail reforms will never benefit farmers in their states.
In Iran, dill is known as 'shevid' and sometimes, is used with rice and called 'shevid-polo'. It also is used in Iranian 'aash' recipes, and similarly, is called sheved in Persian. In India, dill is known as 'Sholpa' in Bengali, shepu (शेपू) in Marathi, sheppi (शेप्पी) in Konkani, savaa in Hindi, or soa in Punjabi. In Telugu, it is called 'Soa-kura' (herb greens). It also is called sabbasige soppu (ಸಬ್ಬಸಿಗೆ ಸೊಪ್ಪು) in Kannada. In Tamil it is known as sada kuppi (சதகுப்பி). In Malayalam, it is ചതകുപ്പ (chathakuppa) or ശതകുപ്പ (sathakuppa). In Sanskrit, this herb is called shatapushpa. In Gujarati, it is known as suva (સૂવા). In India, dill is prepared in the manner of yellow 'moong dal', as a main-course dish. It is considered to have very good antiflatulent properties, so it is used as 'mukhwas', or an after-meal digestive. Traditionally, it is given to mothers immediately after childbirth. In the state of Uttar Pradesh in India, a small amount of fresh dill is cooked along with cut potatoes and fresh fenugreek leaves (Hindi आलू-मेथी-सोया). In Manipur, dill, locally known as pakhon, is an essential ingredient of chagem pomba – a traditional Manipuri dish made with fermented soybean and rice. In Laos and parts of northern Thailand, dill is known in English as Lao coriander (Lao: ຜັກຊີ or Thai: ผักชีลาว), and served as a side with salad yum or papaya salad. In the Lao language, it is called 'phak see', and in Thai, it is known as 'phak chee Lao'.

Magnetic resonance angiography (MRA) generates pictures of the arteries to evaluate them for stenosis (abnormal narrowing) or aneurysms (vessel wall dilatations, at risk of rupture). MRA is often used to evaluate the arteries of the neck and brain, the thoracic and abdominal aorta, the renal arteries, and the legs (called a "run-off"). A variety of techniques can be used to generate the pictures, such as administration of a paramagnetic contrast agent (gadolinium) or using a technique known as "flow-related enhancement" (e.g., 2D and 3D time-of-flight sequences), where most of the signal on an image is due to blood that recently moved into that plane (see also FLASH MRI). Techniques involving phase accumulation (known as phase contrast angiography) can also be used to generate flow velocity maps easily and accurately. Magnetic resonance venography (MRV) is a similar procedure that is used to image veins. In this method, the tissue is now excited inferiorly, while the signal is gathered in the plane immediately superior to the excitation plane—thus imaging the venous blood that recently moved from the excited plane.

In the 1980s, Mister Donut was the largest competitor to Dunkin'. On March 31, 1987, Elie G. Saheb and his business associates acquired the trademark rights for Mister Donut in the United Kingdom and afterwards opened a Mister Donut pilot store and bakery in Fulham, London. On May 2, 1988, the Mister Donut franchise sold the trademark rights for the European market at large. By the 1980s, Mister Donut had over 550 stores in the United States and Canada. In 1989, the British corporate giant Allied-Lyons plc acquired Dunkin' Donuts from Rosenberg for a reported £196 million. After becoming a subsidiary of Allied-Lyons, Dunkin' Donuts immediately acquired Mister Donut from International Multifoods. Mister Donut stores were offered the option to convert to Dunkin', while all remaining Mister Donut franchises in the rest of the world started being operated on their own such as in Japan and El Salvador. Mister Donut sold its Middle East trademarks on October 14, 1995. In July 2005, Allied-Lyons was acquired by Pernod Ricard SA. On December 12, 2005, Pernod Ricard announced that it had agreed to sell Dunkin' Brands, which owned Dunkin' and Mister Donut, to a consortium of three US private equity firms (Thomas H. Lee Partners, the Carlyle Group and Bain Capital LLP) for US$2.43 billion. The closing of the sale occurred on March 1, 2006. In August 2012, Dunkin' Brands became completely independent of the private equity firms. As of 2017, only one Mister Donut store remains in the United States, in Godfrey, Illinois (outside of St. Louis), while there were 10,000 stores worldwide.

Pholcodine is an opioid cough suppressant (antitussive). It helps suppress unproductive coughs and also has a mild sedative effect, but has little or no analgesic effects. It is also known as morpholinylethylmorphine and homocodeine. Pholcodine is found in certain cough lozenges, and more commonly as an oral solution, typically 5 mg / 5 ml. Adult dosage is 5-10 ml up to 3-4 times daily. Pholcodine now largely replaces the previously more common codeine linctus, as it has a much lower potential for dependence. Pholcodine has been widely used as an antitussive agent but by 2023 concerns over its association with anaphylaxis in some circumstances meant that it has been withdrawn from sale in many territories. Pholcodine is not prescribed in the United States where it is classed as a Schedule I drug, the most highly controlled drug category. Following the conclusion of a review of post-marketing safety data by the Medicines and Healthcare products Regulatory Agency, all pholcodine-containing medicines were recalled and withdrawn from the UK as a precaution. The available data has demonstrated that pholcodine use, particularly in the twelve months before general anesthesia with NMBAs (neuromuscular blocking agents), is a risk factor for developing an anaphylactic reaction to NMBAs. In December 2022, the European Medicines Agency recommended their withdrawal in the EU. As of February 2023, the Australian Therapeutic Goods Administration canceled the registration of pholcodine.
=== 1997 constitutional crisis === The Cherokee Nation was seriously destabilized in May 1997 in what was variously described as either a nationalist "uprising" or an "anti-constitutional coup" instigated by Joe Byrd, the Principal Chief. Elected in 1995, Byrd became locked in a battle of strength with the judicial branch of the Cherokee tribe. The crisis came to a head on March 22, 1997, when Byrd said in a press conference that he would decide which orders of the Cherokee Nation's Supreme Court were lawful and which were not. A simmering crisis continued over Byrd's creation of a private, armed paramilitary force. On June 20, 1997, his private militia illegally seized custody of the Cherokee Nation Courthouse from its legal caretakers and occupants, the Cherokee Nation Marshals, the Judicial Appeals Tribunal, and its court clerks. The courts demanded the courthouse's return, but Byrd refused. The Federal authorities of the United States initially refused to intervene because of potential breach of tribal sovereignty. Byrd was required to attend a meeting in Washington, D.C. with the Bureau of Indian Affairs, at which he was compelled to reopen the courts. Byrd served the remainder of his term but lost the 1999 election for Principal Chief to Chad Smith. He was later elected to the Tribal Council in 2013. A new constitution was drafted in 1999 that included procedures for voters to remove officials from office, changed the structure of the tribal council, and removed the need to ask the Bureau of Indian Affairs' permission to amend the constitution.
== Capsaicinoids == The most commonly occurring capsaicinoids are capsaicin (69%), dihydrocapsaicin (22%), nordihydrocapsaicin (7%), homocapsaicin (1%), and homodihydrocapsaicin (1%). Capsaicin and dihydrocapsaicin (both 16.0 million SHU) are the most pungent capsaicinoids. Nordihydrocapsaicin (9.1 million SHU), homocapsaicin and homodihydrocapsaicin (both 8.6 million SHU) are about half as hot. There are six natural capsaicinoids (table below). Although vanillylamide of n-nonanoic acid (Nonivamide, VNA, also PAVA) is produced synthetically for most applications, it does occur naturally in Capsicum species.
The NAS report described the level of lowest exposure from Greer et al. as a "no-observed-effect level" (NOEL). However, there was actually an effect at that level although not statistically significant largely due to small size of study population (four of seven subjects showed a slight decrease in iodide uptake). Reduced iodide uptake was not considered to be an adverse effect, even though it is a precursor to an adverse effect, hypothyroidism. Therefore, additional safety factors, would be necessary when extrapolating from the point of departure to the RfD. Consideration of data uncertainty was insufficient because the Greer, et al. study reflected only a 14-day exposure (=acute) to healthy adults and no additional safety factors were considered to protect sensitive subpopulations like for example, breastfeeding newborns. Although there has generally been consensus with the Greer et al. study, there has been no consensus with regard to developing a perchlorate RfD. One of the key differences results from how the point of departure is viewed (i.e., NOEL or "lowest-observed-adverse-effect level", LOAEL), or whether a benchmark dose should be used to derive the RfD. Defining the point of departure as a NOEL or LOAEL has implications when it comes to applying appropriate safety factors to the point of departure to derive the RfD. In early 2006, EPA issued a "Cleanup Guidance" and recommended a Drinking Water Equivalent Level (DWEL) for perchlorate of 24.5 μg/L.

SR9009 is a synthetic research compound that acts on REV-ERB nuclear receptors. It is not approved for human use and is sold only as a research chemical. Its effects have been studied mainly in cells and rodents.
It binds REV-ERB alpha and REV-ERB beta and changes the expression of genes tied to metabolism and circadian rhythm. These changes can affect mitochondria and energy use in animal models. The exact chain from receptor binding to physiological outcome is still being mapped.
No reliable human trials show that SR9009 improves athletic performance. Some rodent studies report endurance changes, but these results are not proof of human benefit. Its use in sport is prohibited, and quality and safety data are lacking.
Laboratories commonly use liquid chromatography coupled with mass spectrometry to detect SR9009. The method can identify the compound and estimate concentration in a sample. Detection limits depend on the matrix and instrument.
