Retatrutide is an investigational synthetic peptide engineered to activate three distinct hormone receptors within a single molecule. It targets the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor simultaneously. This triagonist design distinguishes it from earlier incretin-based compounds that act on one or two of these pathways. Structural modifications relative to native gut hormones extend its residence time in circulation. The molecule remains under clinical evaluation and is not approved for any indication.
Receptor activation produces downstream effects that differ by tissue. GLP-1 receptor signaling influences appetite regulation and insulin secretion in a glucose-dependent manner. GIP receptor activity contributes to metabolic handling of nutrients and may modulate adipose tissue. Glucagon receptor engagement raises energy expenditure and promotes hepatic lipid turnover, though the balance among these actions in humans is still being characterized. Preclinical models showed reductions in body weight and improved glycemic markers.
Clinical development has progressed through phase 2 trials in adults with obesity and type 2 diabetes, with phase 3 programs reported as ongoing. Reported outcomes include reductions in body weight and improvements in glycemic measures over defined treatment periods. Whether these effects translate into durable benefits after treatment ends remains an open question. Long-term safety data across broad populations are not yet complete, and regulatory decisions have not been announced.
Identification and purity assessment rely on established analytical techniques. Reverse-phase high-performance liquid chromatography separates the compound from related impurities and degradation products. Mass spectrometry confirms molecular identity and detects modifications that change the expected mass. Additional methods such as amino acid analysis or capillary electrophoresis may be used for verification. Small differences in sample preparation can influence results, so procedures are usually controlled and documented in detail. Consistency between runs supports confidence in reported values.
Stability studies examine how the molecule changes under defined conditions of temperature, humidity, and light exposure over time. Results are used to set storage recommendations and shelf-life limits. In practice, lyophilized peptide material is often stored at low temperatures to slow degradation, while reconstituted solutions are handled more carefully because they are generally less stable. Reported stability data apply to specific formulations and conditions, so extrapolation to other preparations requires caution.
Retatrutide is handled in laboratories mainly as a lyophilized solid for analytical and biochemical research. The peptide is typically supplied as a white to off-white powder and is reconstituted in appropriate solvents before use. Because peptide-based molecules are sensitive to temperature, moisture, and repeated freeze-thaw cycles, proper storage conditions affect both stability and measurement accuracy. Laboratories generally follow documented handling procedures to maintain the integrity of the material across experiments.

Several questions about the compound remain unresolved. The durability of weight reduction after treatment stops, the frequency of gastrointestinal side effects, and the long-term cardiovascular profile are topics of ongoing study. Regulatory submissions and phase 3 trial outcomes have not been fully reported in the public literature. Because most available data come from controlled trials rather than general-population use, conclusions about effectiveness outside study settings are provisional. The distinction between established findings and open questions matters when interpreting early coverage of the drug.
Retatrutide is an investigational peptide developed by a pharmaceutical company as a multi-receptor agonist for treating obesity and type 2 diabetes. The compound emerged from research into gut-hormone analogues that act on several receptors simultaneously rather than on a single target. Early preclinical work examined how combined activity at three distinct receptors might produce greater metabolic effects than single-receptor compounds. Published phase 2 results have described substantial reductions in body weight among participants, although the compound remains unapproved in most jurisdictions as of the mid-2020s.
Pharmacologically, retatrutide acts as a triple agonist at the glucagon-like peptide-1 receptor, the glucose-dependent insulinotropic polypeptide receptor, and the glucagon receptor. Activation of the first two receptors is associated with improved insulin secretion and reduced appetite. The glucagon receptor component is thought to increase energy expenditure, a mechanism that distinguishes this molecule from dual-agonist compounds. Researchers continue to investigate how the three activities interact and whether the combined profile offers advantages that justify additional clinical testing.
Body composition is assessed with dual-energy X-ray absorptiometry or comparable methods, which separate fat mass from lean mass. Reported losses include both compartments, and the ratio between them is a subject of ongoing analysis rather than a settled result. Waist circumference, blood pressure, and lipid panels are collected as supporting measures. Resting energy expenditure and substrate oxidation are measured in smaller mechanistic studies, where glucagon receptor activity is expected to matter. These substudies are typically short and small, so their findings carry wide uncertainty.
Interpretation depends on study phase and duration. Phase 2 programs are powered for weight and safety signals, not for cardiovascular or renal outcomes, which require event-driven designs. Gastrointestinal events such as nausea, diarrhea, vomiting, and constipation are the most frequently reported adverse effects and tend to cluster around dose escalation. Small increases in heart rate have been described. Because follow-up after treatment discontinuation is limited, questions about weight regain and durability are open rather than answered.

Other options instead of death include conversion of an individual's consciousness into an AI, joining of a group mind (which can include biological and non-biological consciousnesses), or subliming (usually in association with a group mind). Concerning the lifespan of drones and Minds, given the durability of Culture technology and the options of mindstate backups, it is reasonable to assume that they live as long as they choose. Even Minds, with their utmost complexity, are known to be backed up (and reactivated if they for example die in a risky mission, see GSV Lasting Damage). It is noted that even Minds themselves do not necessarily live forever either, often choosing to eventually sublime or even killing themselves (as does the double-Mind GSV Lasting Damage due to its choices in the Culture-Idiran war).
White sharks range from tropical to temperate and even colder waters around the world with major populations in northwestern and northeastern Pacific, western North Atlantic, the Mediterranean, southern African waters and Oceania. It is also present near the coasts of South America but appears to be uncommon. Shark expert Greg Skomal lists the Farallon Islands, California; Guadalupe Island, Mexico; Cape Cod, Massachusetts; Western Cape, South Africa; Neptune Islands, Australia; and both Stewart Island and the Chatham Islands, New Zealand, as major coastal feeding aggregations. Researchers have also identified an offshore feeding aggregation between western North America and Hawaii dubbed the White Shark Café. White sharks can be found both along the coast and in the open ocean. They are typically close to the surface but may dive to depths of up to 1,300 m (4,300 ft). Deeper dives are more common in the open ocean. Coastal habitats used include nearshore archipelagos, offshore reefs, banks and shoals, and headlands. A 2018 study indicated that white sharks will congregate in patches of warm water in the open ocean. Juvenile white sharks are more limited to shallow coastal waters with temperatures between 14 and 24 °C (57 and 75 °F). Increased sightings of young sharks in areas where they were not previously common, such as Monterey Bay on the central California coast, suggest climate change may be forcing juveniles closer to the poles.
== MrBayes software == MrBayes is a free software tool that performs Bayesian inference of phylogeny. It was originally written by John P. Huelsenbeck and Frederik Ronquist in 2001. As Bayesian methods increased in popularity, MrBayes became one of the software of choice for many molecular phylogeneticists. It is offered for Macintosh, Windows, and UNIX operating systems and it has a command-line interface. The program uses the standard MCMC algorithm as well as the Metropolis coupled MCMC variant. MrBayes reads aligned matrices of sequences (DNA or amino acids) in the standard NEXUS format. MrBayes uses MCMC to approximate the posterior probabilities of trees. The user can change assumptions of the substitution model, priors and the details of the MC³ analysis. It also allows the user to remove and add taxa and characters to the analysis. The program includes, among several nucleotide models, the most standard model of DNA substitution, the 4x4 also called JC69, which assumes that changes across nucleotides occur with equal probability. It also implements a number of 20x20 models of amino acid substitution, and codon models of DNA substitution. It offers different methods for relaxing the assumption of equal substitutions rates across nucleotide sites. MrBayes is also able to infer ancestral states accommodating uncertainty to the phylogenetic tree and model parameters. MrBayes 3 was a completely reorganized and restructured version of the original MrBayes. The main novelty was the ability of the software to accommodate heterogeneity of data sets.

Immunoglobulin G (IgG) antibodies are large heterodimeric molecules, approximately 150 kDa and are composed of two kinds of polypeptide chain, called the heavy (~50kDa) and the light chain (~25kDa). The two types of light chains are kappa (κ) and lambda (λ). By cleavage with enzyme papain, the Fab (fragment-antigen binding) part can be separated from the Fc (fragment crystallizable region) part of the molecule. The Fab fragments contain the variable domains, which consist of three antibody hypervariable amino acid domains responsible for the antibody specificity embedded into constant regions. The four known IgG subclasses are involved in antibody-dependent cellular cytotoxicity. Antibodies are a key component of the adaptive immune response, playing a central role in both in the recognition of foreign antigens and the stimulation of an immune response to them. The advent of monoclonal antibody technology has made it possible to raise antibodies against specific antigens presented on the surfaces of tumors. Monoclonal antibodies can be acquired in the immune system via passive immunity or active immunity. The advantage of active monoclonal antibody therapy is the fact that the immune system will produce antibodies long-term, with only a short-term drug administration to induce this response. However, the immune response to certain antigens may be inadequate, especially in the elderly. Additionally, adverse reactions from these antibodies may occur because of long-lasting response to antigens.
== Fecundity == Fecundity of An. gambiae depends on the detoxification of reactive oxygen species (ROS) by catalase. Reduction in catalase activity significantly reduces reproductive output of female mosquitoes, indicating that catalase plays a central role in protecting oocytes and early embryos from ROS damage.
=== Cultivator model === Beyond "ORF-first" and "transcription-first" scenarios, the proposed "cultivator model" emphasises that selection acting on regulatory environments of nearby pre-existing genes can promote stepwise fixation of new transcripts and, more rarely, protein-coding de novo genes.
Flaps may include skin in their construction. Skin is important for many reasons, but its role in thermoregulation, immune function, and blood supply aid in flap survival. The skin can be divided into three main layers: the epidermis, dermis, and subcutaneous tissue. Blood is mainly supplied to the skin by two networks of blood vessels. The deep network lies between the dermis and the subcutaneous tissue, while the shallow network lies within the papillary layer of the dermis. The epidermis is supplied by diffusion from this shallow network and both networks are supplied by collaterals, and by perforating arteries that bring blood from deeper layers either between muscles (septocutaneous perforators) or through muscles (musculocutaneous perforators). This robust and redundant blood supply is important in flap surgery, because flaps are cut off from other blood vessels when they are raised and removed from surrounding native tissue. The remaining blood supply must then keep the tissue alive until additional blood supply can be formed through angiogenesis.

Calpainopathy is the most common type of autosomal recessive limb-girdle muscular dystrophy (LGMD). It preferentially affects the muscles of the hip girdle and shoulder girdle. No disease modifying pharmaceuticals have been developed as of 2019, although physical therapy, lifestyle modification, and orthopedic surgery can address symptoms.
Gearbox announced the formation of Gearbox Studios as a third company under the Gearbox Entertainment Company on October 6, 2021, to oversee television and film productions, with Pitchford serving as Gearbox Studios president alongside as president and CEO of the parent company. Former CTO Steve Jones was named as president of Gearbox Software in Pitchford's place. Embracer announced it intent to acquire Perfect World Entertainment in December 2021 and placing the group, including its publishing arm and Cryptic Studios, under the Gearbox Entertainment operating group. Following its acquisition in April 2022, Perfect World Entertainment was rebranded as Gearbox Publishing San Francisco, with the naming to be applied retroactively to past games published under Perfect World. In April 2022, Gearbox Entertainment announced it will acquire Lost Boys Interactive, which had supported Gearbox in Tiny Tina's Wonderlands. Later that November, Gearbox acquired the Risk of Rain IP from Hopoo Games, while Embracer transferred ownership of Volition to Gearbox Entertainment from Deep Silver following poor reception to its Saints Row reboot. The studio would later shut down the following year due to the restructuring of Embracer Group. That same month, Eidos Shanghai, another studio under the Embracer Group, was transferred to Gearbox Publishing San Francisco and rebranded as Gearbox Studio Shanghai. Gearbox Entertainment acquired Captured Dimensions, a 3D modeling company from Texas, in January 2023.
Due to decreased levels of androgens and/or neurosteroids, 5α-reductase inhibitors may slightly increase the risk of depression (~2.0% incidence). There are reports that a small percentage of men may experience persistent sexual dysfunction and adverse mood changes even after discontinuation of 5α-reductase inhibitors. Some of the possible side effects of 5α-reductase inhibitors in men, such as gynecomastia and sexual dysfunction, are actually welcome changes for many transgender women. In any case, caution may be warranted in using 5α-reductase inhibitors in transgender women, as this group is already at a high risk for depression and suicidality.
==== Thalidomide ==== Despite the therapeutic potential of anti-angiogenesis drugs, they can also be harmful when used inappropriately. Thalidomide is one such antiangiogenic agent. Thalidomide was given to pregnant women to treat nausea. However, when pregnant women take an antiangiogenic agent, the developing fetus will not form blood vessels properly, thereby preventing the proper development of fetal limbs and circulatory systems. In the late 1950s and early 1960s, thousands of children were born with deformities, most notably phocomelia, as a consequence of thalidomide use.

It is a synthetic peptide triagonist that engages GIP, GLP-1, and glucagon receptors. Investigational compounds in this class are studied for metabolic conditions rather than for a single organ system.
No regulatory agency has approved it for any indication. It remains an investigational product studied within controlled clinical trial programs.
A dual agonist engages two receptor targets, typically GIP and GLP-1. A triagonist adds glucagon receptor activity, which is intended to influence energy expenditure alongside appetite and glucose handling.
Reverse-phase liquid chromatography and mass spectrometry are the most common techniques. Chromatography assesses purity, while mass spectrometry confirms molecular identity. Additional methods may be applied when higher confidence is required.
