Laboratory studies have reported that AOD9604 can increase lipolysis and reduce lipid accumulation in fat cells. The precise molecular target remains uncertain, and the compound does not appear to activate the growth hormone receptor in the same way as full-length hGH. Proposed mechanisms include effects on beta-adrenergic signaling and enzymes involved in fatty acid synthesis, but these pathways are not firmly established. Because most evidence comes from cell and animal models, whether the same effects occur in humans is an open question.
Clinical development of AOD9604 included trials in people with obesity, but the results did not lead to approval as a prescription medicine in major markets. Interest later shifted to research settings and to unapproved products marketed for body composition. Regulatory agencies have questioned whether the peptide qualifies as a dietary ingredient, and some have issued warnings about its presence in supplements. Long-term human safety data are limited, and questions about efficacy, dosing, and target populations remain unresolved.
AOD9604 is a synthetic peptide modeled on the C-terminal region of human growth hormone. It corresponds to a short sequence near the end of the 191-amino-acid hormone, often described as residues 176–191 or a related fragment. Researchers designed it to separate metabolic effects from the growth-promoting actions of full-length growth hormone. Early work in the 1990s explored it as a candidate for weight and lipid disorders. It is not a naturally circulating hormone fragment produced in large amounts.
Research interest in AOD-9604 often focuses on whether it can influence lipid metabolism without the growth-promoting or glucose-related effects of full-length hGH. This question remains unresolved, and findings depend on model, dose, and measurement method. Some reviews treat the peptide as a historical obesity candidate rather than an active therapeutic. Others cite it in discussions of peptide fragments, metabolic signaling, and performance-enhancing substances. Clear conclusions are limited by the small number of rigorous, independent human studies.
AOD-9604 has been investigated primarily as a potential treatment for obesity and related metabolic conditions. Early laboratory work examined its effects on fat cells, and later studies moved into animal models and human clinical trials. Some trials reportedly reached Phase II, but the program did not lead to an approved medicine. Published summaries often note that weight-loss results were modest or inconsistent. The full trial data are not all publicly available in detail.

AOD-9604 is prohibited in sport by the World Anti-Doping Agency under the peptide hormone class. Its presence in a sample can be detected through mass spectrometry-based methods, although the exact assay depends on the laboratory. In research settings, material is often supplied as a lyophilized powder for reconstitution. Buyers and researchers should note that products labeled AOD-9604 may vary in purity and actual peptide content. Analytical certificates and independent testing are common ways to verify identity, but no global harmonized standard exists for all commercial lots.
AOD-9604 is a synthetic peptide whose sequence is modeled on the C-terminal region of human growth hormone. Published descriptions commonly place it as a modified fragment corresponding to hGH amino acids 176–191, with a tyrosine residue added or retained at the N-terminus to support detection and handling. It is not intact growth hormone and lacks the full receptor-binding architecture of the parent protein. The molecule was developed as a research candidate for metabolic studies rather than as a replacement for growth hormone therapy. Its identity is defined by its amino acid sequence rather than by any single commercial preparation.
Regulatory interest in AOD-9604 increased after high-profile anti-doping cases involving peptide products. In some cases, the substance was supplied under alternative names or in compounded preparations, complicating traceability. Sports tribunals and anti-doping panels have discussed whether the peptide was explicitly banned at the time of use, leading to clarifications by the World Anti-Doping Agency. For consumers and researchers, the legal status can vary by jurisdiction, and products marketed as research chemicals may lack independent quality verification.
AOD-9604 is listed as a prohibited substance in sport by the World Anti-Doping Agency. It falls under the peptide hormones, growth factors, related substances, and mimetics class on the prohibited list. Anti-doping organizations treat its presence in an athlete's sample as an adverse finding unless a therapeutic use exemption applies. The prohibition reflects concerns about performance enhancement in competitive settings and the difficulty of distinguishing exogenous peptide use from endogenous hormone fragments.
Detection of AOD-9604 in biological samples relies on analytical techniques capable of distinguishing a small synthetic peptide from related endogenous sequences. Liquid chromatography coupled with tandem mass spectrometry is commonly used for confirmatory analysis. Sample preparation may involve immunoaffinity enrichment or solid-phase extraction to concentrate the peptide. Because the molecule is small and may be present at low concentrations, assay sensitivity and specificity are ongoing analytical challenges. Laboratories also validate methods against reference materials when available.
Detection and characterization of AOD-9604 in research and anti-doping settings typically rely on mass spectrometry coupled with liquid chromatography. These methods can identify the peptide by its mass and fragmentation pattern. Immunoassays may also be used in some screening contexts, but they can cross-react with related peptides. Because the molecule is small and may be present at low concentrations, sample preparation and method validation are important. Confirmatory analysis usually requires comparison with a certified reference standard.
In laboratory settings, AOD-9604 is commonly supplied as a lyophilized powder and stored cold to limit degradation. Reconstituted solutions are typically kept refrigerated or frozen, depending on the buffer and concentration, and protected from repeated freeze-thaw cycles. Stability can be influenced by pH, temperature, and the presence of proteases. Purity is usually assessed by high-performance liquid chromatography and mass spectrometry. These practices support reproducibility, but they do not imply safety or efficacy for any human use.
Regulatory status: AOD-9604 is not approved as a therapeutic drug in the United States, European Union, or other major markets. It is listed by the World Anti-Doping Agency as a prohibited substance in sport, specifically under growth hormone fragments. Many jurisdictions restrict its sale for human consumption. Products marketed online may not meet pharmaceutical quality standards. The legal status varies by country and often depends on whether the material is presented as a research chemical, supplement, or drug.
AOD9604 is commonly supplied as a white to off-white lyophilized powder. The powder is typically stored at -20 °C or below, protected from light and moisture, because peptides can degrade through oxidation, hydrolysis, or aggregation. If it is reconstituted for laboratory use, an appropriate aqueous buffer or solvent is chosen, and the solution is kept cold and handled to avoid repeated freeze-thaw cycles. These practices support stability but do not imply suitability for human use.
Identity and purity are usually assessed with reversed-phase high-performance liquid chromatography and mass spectrometry. Reversed-phase HPLC separates the peptide from related impurities and can estimate purity by ultraviolet absorbance, while mass spectrometry confirms the molecular mass and detects modifications. Peptide mapping, amino acid analysis, and disulfide mapping may be used when the sequence or disulfide arrangement must be verified. Because AOD9604 contains cysteine residues, oxidation and disulfide isomers are possible quality concerns in synthetic batches.
Boosted considerably by the arrival of three South African brigades during the last months of 1940, the Commonwealth forces in Kenya had expanded to three divisions by the end of the year. No. 237 Squadron was relieved by South African airmen and redeployed to the Sudan in September. Rebasing at Khartoum, No. 237 Squadron undertook regular reconnaissance, dive-bombing and strafing sorties during October and November 1940. Meanwhile, the Southern Rhodesian Anti-Tank Battery arrived in Kenya in October and, following a period of training, received 2-pounder guns and joined the front at Garissa around the turn of the new year. No. 237 Squadron was partially re-equipped during January 1941, receiving some Westland Lysander Mk IIs, but most of the squadron continued operating Hardys. The British forces in Kenya under General Alan Cunningham, including Rhodesian officers and NCOs in the King's African Rifles and the Nigeria and Gold Coast Regiments, as well as the South African 1st South African Infantry Division, advanced into Abyssinia and Italian Somaliland during late January and February 1941, starting with the occupation of the ports of Kismayo and Mogadishu. The Italians retreated to the interior. No. 237 Squadron meanwhile provided air support to the 4th Indian Infantry Division and 5th Indian Infantry Division during Lieutenant-General William Platt's offensive into Eritrea from the Sudan, attacking ground targets and engaging Italian fighters. One of the Rhodesian Hardys was shot down near Keren on 7 February with the loss of both occupants.
== Causes == The pathophysiology of polymyalgia rheumatica is not well-understood. Evidence shows that there is likely a combined genetic and environmental pathophysiology behind the disease, but concrete identification of the causes, including whether or not polymyalgia rheumatica is an autoimmune disease, remains elusive. It is, at the very least, an immune-mediated disease, with both innate and adaptive immune system elements being known to play a role. Infectious diseases have historically been hypothesized as a likely trigger for disease in genetically susceptible people. Individual studies have sometimes found correlations between specific pathogens and development of the disease, but broader analysis fails to find significant correlations. Proposed causative pathogens, none of which have been proven, include:
In 2023, it was the 246th most commonly prescribed medication in the United States, with more than 1 million prescriptions. It is available as a generic medication. In 2023, the combination of dexamethasone with neomycin and polymyxin B was the 260th most commonly prescribed medication in the United States, with more than 1 million prescriptions; and the combination of dexamethasone with ciprofloxacin was the 283rd most commonly prescribed medication in the United States, with more than 700,000 prescriptions;

Injury in humans has been studied extensively for its importance in medicine. Much of medical practice, including emergency medicine and pain management, is dedicated to treating injuries. The World Health Organization has developed a classification of injuries in humans by categories, including mechanism, objects/substances producing injury, place of occurrence, activity when injured, and the role of human intent. In addition to physical harm, injuries can cause psychological harm, including post-traumatic stress disorder, or depression (mood).

Cannabis is indigenous to Central or South Asia and its uses for fabric and rope dates back to the Neolithic age in China and Japan. It is unclear when cannabis first became known for its psychoactive properties. The oldest archeological evidence for the burning of cannabis was found in Romanian kurgans dated 3,500 BC, and scholars suggest that the drug was first used in ritual ceremonies by Proto-Indo-European tribes living in the Pontic-Caspian steppe during the Chalcolithic period, a custom they eventually spread throughout Western Eurasia during the Indo-European migrations. Some research suggests that the ancient Indo-Iranian drug soma, mentioned in the Vedas, sometimes contained cannabis. This is based on the discovery of a basin containing cannabis in a shrine of the second millennium BC in Turkmenistan. Cannabis was known to the ancient Assyrians, who discovered its psychoactive properties through the Iranians. Using it in some religious ceremonies, they called it qunubu (meaning "way to produce smoke"), a probable origin of the modern word cannabis. The Iranians also introduced cannabis to the Scythians, Thracians and Dacians, whose shamans (the kapnobatai – "those who walk on smoke/clouds") burned cannabis infructescence to induce trance. The plant was used in China before 2800 BC, and found therapeutic use in India by 1000 BC, where it was used in food and drink, including bhang.
While penetrating head trauma accounts for only a small percentage of all traumatic brain injuries (TBI), it is associated with a high mortality rate, and only a third of people with penetrating head trauma survive long enough to arrive at a hospital. Injuries from firearms are the leading cause of TBI-related deaths. Penetrating head trauma can cause cerebral contusions and lacerations, intracranial hematomas, pseudoaneurysms, and arteriovenous fistulas. The prognosis for penetrating head injuries varies widely. Penetrating facial trauma can pose a risk to the airway and breathing; airway obstruction can occur later due to swelling or bleeding. Penetrating eye trauma can cause the globe of the eye to rupture or vitreous humor to leak from it, and presents a serious threat to eyesight.
== Ecology == Bilberry plants can suffer from bilberry blight, caused by Phytophthora kernoviae. There have been severe outbreaks in Staffordshire, England. Bilberry is used as a food plant by the larvae of some Lepidoptera species.
=== Australia === Dialysis is provided without cost to all patients through Medicare, with 75% of all dialysis being administered as haemodialysis to patients three times per week in a dialysis facility. The Northern Territory has the highest incidence rate per population of haemodialysis, with Indigenous Australians having higher rates of Chronic Kidney Disease and lower rates of functional kidney transplants than the broader population. The remote Central Australian town of Alice Springs, despite having a population of approximately 25000, has the largest dialysis unit in the Southern Hemisphere. Many people must move to Alice Springs from remote Indigenous communities to access health services such as haemodialysis, which results in housing shortages, overcrowding, and poor living conditions.
==== 1993–1997 ==== Under Bill Clinton (President 1993–2001) and P. V. Narasimha Rao (Prime Minister 1991–1996) both sides mishandled relations, according to Arthur G. Rubinoff. Clinton simultaneously pressured India to liberalize its economy while criticizing New Delhi on human rights and nuclear issues. In the face of criticism from Washington and opposition at home, Indian leaders lost their enthusiasm for rapprochement and reverted to formalistic protocol over substantive diplomacy. The Brown Amendment that restored American aid to Pakistan in 1995 was an irritant. In returning to a Cold War style rhetoric, Indian parliamentarians and American congressmen demonstrated their unwillingness to establish a new relationship.

Blood is filtered at the kidneys and liver. The body consists of a number of body cavities, separated areas which house different organ systems. The brain and central nervous system reside in an area protected from the rest of the body by the blood brain barrier. The lungs sit in the pleural cavity. The intestines, liver, and spleen sit in the abdominal cavity. Height, weight, shape and other body proportions vary individually and with age and sex. Body shape is influenced by the distribution of bones, muscle and fat tissue.
=== Pharmacodynamics === Buserelin is a GnRH agonist, or an agonist of the GnRH receptor. It is a superagonist of the GnRH receptor with potency for induction of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion of about 20 to 170 times that of GnRH itself. By activating the GnRH receptor in the pituitary gland, buserelin induces the secretion of LH and FSH from the gonadotrophs of the anterior pituitary, which travel to the gonads through the bloodstream and activate gonadal sex hormone production as well as stimulate spermatogenesis in men and induce ovulation in women. With chronic administration of buserelin however, the GnRH receptor becomes desensitized and completely stops responding both to buserelin and to endogenous GnRH. This is because GnRH is normally released from the hypothalamus in pulses, which keeps the GnRH receptor sensitive, whereas chronic buserelin administration results in more constant exposure and desensitization of the receptor. The profound desensitization of the GnRH receptor results in a loss of LH and FSH secretion from the anterior pituitary and a consequent shutdown of gonadal sex hormone production, markedly diminished or abolished spermatogenesis in men, and anovulation in women. In men, approximately 95% of circulating testosterone is produced by the testes, with the remaining 5% being derived from the adrenal glands. In accordance, GnRH analogues like buserelin can reduce testosterone levels by about 95% in men.
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. Only these 22 appear in the genetic code of life. Amino acids can be classified according to the locations of the core structural functional groups (alpha- (α-), beta- (β-), gamma- (γ-) amino acids, etc.); other categories relate to polarity, ionization, and side-chain group type (aliphatic, acyclic, aromatic, polar, etc.). In the form of proteins, amino-acid residues form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life on Earth and its emergence. Amino acids are formally named by the IUPAC-IUBMB Joint Commission on Biochemical Nomenclature in terms of the fictitious "neutral" structure shown in the illustration. For example, the systematic name of alanine is 2-aminopropanoic acid, based on the formula CH3−CH(NH2)−COOH. The Commission justified this approach as follows:
GCaMP is a genetically encoded calcium indicator (GECI) initially developed in 2001 by Junichi Nakai. It is a synthetic fusion of green fluorescent protein (GFP), calmodulin (CaM), and M13, a peptide sequence from myosin light-chain kinase. When bound to Ca2+, GCaMP fluoresces green with a peak excitation wavelength of 480 nm and a peak emission wavelength of 510 nm. It is used in biological research to measure intracellular Ca2+ levels both in vitro and in vivo using virally transfected or transgenic cell and animal lines. The genetic sequence encoding GCaMP can be inserted under the control of promoters exclusive to certain cell types, allowing for cell-type specific expression of GCaMP. Since Ca2+ is a second messenger that contributes to many cellular mechanisms and signaling pathways, GCaMP allows researchers to quantify the activity of Ca2+-based mechanisms and study the role of Ca2+ ions in biological processes of interest.
=== Proposed names === In September 1992, the German group suggested the name nielsbohrium with symbol Ns to honor the Danish physicist Niels Bohr. The Soviet scientists at the Joint Institute for Nuclear Research in Dubna, Russia had suggested this name be given to element 105 (which was finally called dubnium) and the German team wished to recognise both Bohr and the fact that the Dubna team had been the first to propose the cold fusion reaction, and simultaneously help to solve the controversial problem of the naming of element 105. The Dubna team agreed with the German group's naming proposal for element 107. There was an element naming controversy as to what the elements from 104 to 106 were to be called; the IUPAC adopted unnilseptium (symbol Uns) as a temporary, systematic element name for this element. In 1994 a committee of IUPAC recommended that element 107 be named bohrium, not nielsbohrium, since there was no precedent for using a scientist's complete name in the naming of an element. This was opposed by the discoverers as there was some concern that the name might be confused with boron and in particular the distinguishing of the names of their respective oxyanions, bohrate and borate. The matter was handed to the Danish branch of IUPAC which, despite this, voted in favour of the name bohrium, and thus the name bohrium for element 107 was recognized internationally in 1997; the names of the respective oxyanions of boron and bohrium remain unchanged despite their homophony.

AOD9604 is a synthetic peptide based on a C-terminal segment of human growth hormone. It is manufactured by chemical peptide synthesis rather than extracted from human tissue. The sequence is often described as hGH fragment 176–191 or a close variant.
It is not approved as a prescription drug in the United States or the European Union for any indication. Regulatory status can differ by country, and it is often sold as a research chemical or in unapproved products. Such products are not equivalent to an approved medicine.
In the studies reported so far, AOD9604 does not appear to act through the growth hormone receptor and has not shown the typical IGF-1 increase caused by full-length hGH. Human data are limited, so this remains an area of uncertainty. It should not be assumed to have the same effects as hGH.
No major medicines regulator appears to have approved AOD-9604 for human therapeutic use. It has been studied in clinical trials, but those programs did not result in a marketed drug.
