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.
AOD-9604 drew attention in the 1990s and 2000s as a potential anti-obesity agent. Early work explored both injectable and oral routes, which is unusual for a peptide of this size. Animal studies reported changes in fat metabolism without the growth-promoting or insulin-like effects associated with full-length growth hormone. Subsequent human trials produced mixed or modest results, and the compound did not obtain regulatory approval for weight management in major markets. It remains known mainly through research literature, sports anti-doping listings, and non-approved supplement advertising.
Regulatory bodies have taken different approaches to AOD-9604. It is not approved as a prescription medicine by major agencies such as the U.S. Food and Drug Administration or the European Medicines Agency. In sport, the World Anti-Doping Agency prohibits peptide hormones, growth factors, and related substances, and AOD-9604 has been treated as a prohibited substance. These regulatory decisions reflect concerns about safety, efficacy, and potential misuse rather than proof of benefit.
Research on AOD-9604 also examines how the peptide is measured in biological samples. Analytical methods may include liquid chromatography coupled with mass spectrometry, immunoassays, or both. Detection can be challenging because the peptide is small and may be present at low concentrations. Published methods vary in sensitivity and specificity, so comparative interpretation requires attention to validation details. The presence of related hGH fragments can complicate identification in some matrices.
AOD-9604 has been investigated mainly in the context of body fat and metabolic endpoints. Some early animal and small human studies reported changes in fat mass or lipid markers, but findings were not uniform. Larger, well-controlled trials that would establish efficacy are lacking in the public literature. As a result, claims about weight loss or metabolic benefit remain investigational rather than established. The distinction between a research finding and a proven clinical outcome is central to discussing this peptide.

AOD-9604 is a synthetic peptide whose sequence matches the C-terminal fragment of human growth hormone, specifically residues 176 through 191. This region differs from the full hormone in its receptor interactions. The peptide is not a growth hormone secretagogue and does not bind the growth hormone receptor in the same manner. Researchers have examined it for effects on lipid metabolism, but its exact pharmacological profile remains an active area of study.
Development of AOD-9604 began in the 1990s as scientists sought to isolate metabolic effects of growth hormone without its growth-promoting actions. Early laboratory work focused on fat cells and animal models. Several human trials followed, examining changes in body composition and fat mass. Results have been mixed, and the peptide has not progressed to widespread clinical approval. Interest continues in research settings, particularly regarding its mechanism and potential metabolic targets.
Regulatory status varies by country. In the United States, AOD-9604 is not approved as a prescription drug. It is sometimes sold as a research chemical or dietary supplement, though such marketing may fall outside legal frameworks. The World Anti-Doping Agency prohibits its use in sport. Researchers must obtain it through legitimate suppliers and follow institutional rules. Its legal classification continues to evolve as authorities increasingly assess peptide products more broadly.
AOD-9604 is a synthetic peptide modeled on the C-terminal region of human growth hormone. It is often described as hGH fragment 176-191. Research interest arose because it was designed to isolate possible effects on fat metabolism from other actions of growth hormone. It is not a full growth hormone molecule. Its development history includes early laboratory and animal studies followed by human trials. The peptide has been examined in laboratory, animal, and limited human studies.
The compound has been studied as a potential treatment for obesity and related metabolic conditions. Published trials have examined changes in body weight, fat mass, and safety markers over limited durations. Results have been mixed or modest, and no large-scale outcome trials are established. Regulatory agencies in several countries have not approved it as a therapeutic drug. Some commercial products have been marketed outside regulated pharmaceutical channels, which raises questions about quality and claims.
In the scientific literature, AOD-9604 appears in reviews of growth hormone fragments and in discussions of peptide-based metabolic research. Some sources distinguish it from growth hormone itself, while others group it with compounds marketed for weight management. The evidence base is small compared with approved obesity medications. Questions about long-term efficacy and clinical relevance remain open, and independent replication of key findings is limited. Most published reports are early-stage and exploratory.
=== Cinema and cultural workers === In July 2024, the Karnataka Legislative Assembly passed the Karnataka Cine and Cultural Activists (Welfare) Bill, providing for a welfare framework for workers in the cinema and cultural sector. The legislation included a proposed 2 percent cess on movie tickets and OTT subscriptions and provided for a welfare board.

Lula stated during the 2022 election campaign and after taking office that his government will consistently focus on to "bring back Brazil to the world stage", meaning the country will seek to rebuild ties cut or damaged during Bolsonaro's presidency, and expand its foreign relations worldwide. On 9 December 2022 Lula announced that to head the Ministry of Foreign Affairs (Itamaraty) he had chosen Brazilian ambassador, career diplomat and former foreign minister Mauro Vieira. As an effort to empower women diplomats, he picked ambassador and career diplomat Maria Laura da Rocha as Itamaraty's deputy foreign minister and Maria Luiza Ribeiro Viotti as Brazil's ambassador to the US, both the first women to ever hold those positions. More women are also expected to be appointed to top positions.
The side corridors had paintings of Jataka stories, while the back corridor behind the niche had a bench or pedestal along the back wall for the display of the Parinirvana of the Buddha, with deities flying over. On the opposite wall was a scene of the Cremation of the Buddha. Grünwedel sent most of the murals to Germany. A headless wooden statue of a Dhyanasana Buddha, about 164 cm (65 inches) tall, was found in the cave. The murals and the paintings of the ceiling are generally attributed to Cave 181, but some authors attribute them to Cave 178 instead. To add to the confusion, von Le Coq wrote in 1924 that the paintings of the ceiling actually came from barrel-vaulted Cave 184, and he claimed that Grünwedel, who accomplished the removal of the murals in 1906–1907, wrongly described the vault as being "tent-like". Access to cave 181 has remained difficult, and it has also been claimed that it was never painted.

Matches in Team Fortress Classic typically feature two teams, one red and one blue, and nine playable character classes. Each character class has a set of weapons and abilities unique to that specific class. This differentiation between classes makes for rock-paper-scissors-esque gameplay that requires teammates to work together in order to effectively achieve the objective. The class-system also encourages players to vary their selection of classes and utilize certain classes in conjunction with one another to gain the advantage. In Team Fortress Classic, a server can hold up to 32 players simultaneously, and matches can be played in a number of game modes, each featuring different objectives.
=== Obstructive sleep apnea in pregnancy === Sleep apnea can result in intermittent hypoxia and has been increasing in prevalence due in part to the obesity epidemic. The known maternal risk factors for autism diagnosis in her offspring are similar to the risk factors for sleep apnea. For example, advanced maternal age, maternal obesity, maternal type 2 diabetes and maternal hypertension all increase the risk of autism in her offspring. Likewise, these are all known risk factors for sleep apnea. One study found that gestational sleep apnea was associated with low reading test scores in children and that this effect may be mediated by an increased risk of the child having sleep apnea themselves. Another study reported low social development scores in 64% of infants born to mothers with sleep apnea compared to 25% of infants born to controls, suggesting sleep apnea in pregnancy may have an effect on offspring neurodevelopment. There was also an increase in the amount of snoring the mothers with sleep apnea reported in their infants when compared to controls. Children with sleep apnea have "hyperactivity, attention problems, aggressivity, lower social competency, poorer communication, and/or diminished adaptive skills". One study found significant improvements in ADHD-like symptoms, aggression, social problems and thought problems in autistic children who underwent adenotonsillectomy for sleep apnea. Sleep problems in autism have been linked in a study to brain changes, particularly in the hippocampus, though this study does not prove causation.

The Russell 3000 is primarily subdivided into two other indices, the large-cap Russell 1000 and the small-cap Russell 2000. Those two indices are disjoint, and combining them results in exactly the Russell 3000. As of April 30, 2025, the Russell 1000 comprised about 95% of the Russell 3000's total market capitalization, and the Russell 2000 comprised the approximate remaining 5%. Most other indices in the Russell US series are also subsets of the Russell 3000.
== Research and career == Franz became an assistant professor at Duke University in 2003. She is an Associate member of the Duke Cancer Institute. In 2005, Franz was awarded an National Science Foundation CAREER Award. She was made a Sloan Research Fellow in 2008 and promoted to professor in 2015. Franz has investigated the use of cellular metals in antimicrobial resistance. For example, by disrupting the amount of iron in a cell it is possible to withhold an essential pathogen, limiting the growth of microbes. On the other hand, copper can be used to control the growth of microbes, and immune cells appear to move copper to kill pathogens. At the same time, pathogens try to use copper to enhance their resistance and likelihood of survival. Franz attempts to use copper in the same way as biological systems to target antimicrobial agents. She has looked at iron and copper as ionophores; which are important in the virulence of Cryptococcus neoformans. Franz also works on anti-cancer prochelators; molecules that do not have much affinity for metal ions, but can be triggered until they undergo a chemical conversion. Cancer cells have different metallomes than normal cells. For example, prostate cancer results in the overexpression of copper trafficking proteins, causing a high level of copper. She looks to target these copper ions by creating prochelators that become activated in the microenvironment of cancer.
== Research == Limited clinical studies have provided weak evidence for the use of frankincense resin in certain disease conditions, but the inconsistent, low quality of research remains inconclusive for determining any effect.
