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.
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.
Each receptor contributes a different physiological effect. Activation of the GLP-1 receptor slows gastric emptying and reduces appetite signaling in the brain. GIP receptor activity influences insulin secretion and lipid handling, while glucagon receptor stimulation raises energy use and fat oxidation. Combining these pathways is intended to produce weight loss beyond what single- or dual-receptor agonists achieve. Researchers attribute the observed potency to simultaneous engagement of all three targets, though the exact contribution of each receptor to overall effect remains under investigation.
Clinical development has advanced through phase 2 trials in adults with obesity and type 2 diabetes. Reported phase 2 results described substantial average weight reduction over roughly forty-eight weeks of weekly dosing. A phase 3 program is ongoing to confirm efficacy and assess long-term safety. Because the compound has not received regulatory approval, it is not available as a prescription product. Public discussion of retatrutide often conflates trial findings with marketed status, an important distinction when interpreting coverage of the topic.

Human evidence remains limited to controlled studies. A phase 2 trial in adults with obesity reported large, dose-dependent reductions in body weight over 48 weeks, with gastrointestinal events as the most frequently recorded adverse effect. Phase 3 programs designated TRIUMPH, for obesity, and TRANSCEND, for type 2 diabetes, are intended to confirm efficacy and to characterize safety in larger populations. Related studies are examining conditions such as knee osteoarthritis in people with obesity and metabolic liver disease. Open questions include long-term tolerability, effects on lean mass, and what happens after treatment is stopped.
Retatrutide is an investigational synthetic peptide that acts on three receptor targets at once: glucose-dependent insulinotropic polypeptide, glucagon-like peptide-1, and glucagon. It is developed by Eli Lilly and appears in the literature and in trial registries under the code LY3437943. The molecule belongs to a class of engineered peptides designed to resist rapid breakdown and permit infrequent subcutaneous administration. No regulatory agency has approved it for clinical use, and all available human data come from controlled trials rather than from routine practice.
The intended pharmacology combines three signals in one molecule. GLP-1 receptor activation reduces appetite and slows gastric emptying, effects already exploited by approved incretin-based therapies. GIP receptor engagement is associated with improved insulin sensitivity and with direct effects on adipose tissue, although how much it contributes to overall outcomes is still debated. Glucagon receptor agonism raises energy expenditure and supports hepatic lipid handling, a mechanism that also tends to increase glucose output. The triple profile is hypothesized to produce a larger metabolic effect than single or dual agonism, but the relative weight of each receptor in humans is not settled.
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.
Characterising a peptide of this size relies on a combination of chromatographic and mass spectrometric techniques. Reversed-phase high-performance liquid chromatography separates the intact molecule from related impurities, while electrospray mass spectrometry confirms molecular mass and detects truncation or oxidation products. Peptide mapping after enzymatic digestion verifies the amino acid sequence and locates modified residues. Because the molecule carries a lipid chain, assays must also distinguish the correctly conjugated product from incompletely acylated species.
Peptides in this class degrade mainly through hydrolysis, oxidation, and aggregation. The lipid modification improves plasma residence time but can also promote self-association in aqueous solution at higher concentrations. Oxidation of methionine and deamidation of asparagine residues are common chemical liabilities that accumulate during storage. Stability studies therefore track purity loss, aggregate formation, and changes in receptor-binding potency over time under defined temperature and humidity conditions.
All nuclear data not otherwise stated is from the standard source: Twenty-four neptunium radioisotopes have been characterized, with the most stable being 237Np with a half-life of 2.144 million years, 236Np with a half-life of 153,000 years, and 235Np with a half-life of 396.1 days. All of the remaining radioactive isotopes have half-lives that are less than 5 days. Isotopes lighter than the most stable one, 237Np, decay primarily by electron capture, although some also decay by alpha emission to become protactinium. 237Np itself, being the beta-stable isobar of mass number 237, decays by alpha to 233Pa, with very rare spontaneous fission. Heavier isotopes generally decay by beta emission. The decay of 237Np eventually yields bismuth-209 and thallium-205, unlike most other common heavy nuclei which decay into isotopes of lead. This decay chain is known as the neptunium series. This decay chain was virtually absent on Earth due to the short half-lives of all of its isotopes above bismuth-209, but is now being resurrected thanks to artificial production of neptunium (and uranium-233) on the tonne scale.
Naturally occurring ytterbium (70Yb) is composed of seven stable isotopes: 168Yb, 170Yb–174Yb, and 176Yb, with 174Yb being the most abundant (31.90% natural abundance). 30 radioisotopes have been characterized, with the most stable being 169Yb with a half-life of 32.014 days, 175Yb with a half-life of 4.185 days, and 166Yb with a half-life of 56.7 hours. All of the remaining radioactive isotopes have half-lives that are less than 2 hours, with the majority of them being less than 20 minutes. This element also has 18 meta states, with the most stable being 169mYb (half-life 46 seconds). The known isotopes of ytterbium range from 149Yb to 189Yb. The primary decay mode before the most abundant stable isotope, 174Yb is electron capture giving thulium isotopes; the primary mode after is beta emission giving lutetium isotopes. Of interest to modern quantum optics, the different ytterbium isotopes follow either Bose–Einstein statistics or Fermi–Dirac statistics, leading to different behavior in optical lattices.
In order to determine the composition of the East German representatives in the Bundestag between German reunification and the first post-reunification elections in December 1990, the results of the 1990 Volkskammer election were recounted, using the new states of Germany as constituencies. This was possible since the original election results were declared on the Kreis level, and the states were re-established by simply amalgamating Kreise together. The results in each Kreis forming a state were summed up to determine the statewide result. The recount fixed the number of Volkskammer members from each party who would be co-opted into the Bundestag.
=== Drug delivery === Researchers at Monash University discovered that a sheet of graphene oxide can be transformed into liquid crystal droplets spontaneously—like a polymer—simply by placing the material in a solution and manipulating the pH. The graphene droplets change their structure in the presence of an external magnetic field. This finding raises the possibility of carrying a drug in graphene droplets and releasing the drug upon reaching the targeted tissue by making the droplets change shape in a magnetic field. Another possible application is in disease detection if graphene is found to change shape at the presence of certain disease markers such as toxins. A graphene 'flying carpet' was demonstrated to deliver two anti-cancer drugs sequentially to the lung tumor cells (A549 cell) in a mouse model. Doxorubicin (DOX) is embedded onto the graphene sheet, while the molecules of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) are linked to the nanostructure via short peptide chains. Injected intravenously, the graphene strips with the drug payload preferentially concentrate to the cancer cells due to common blood vessel leakage around the tumor. Receptors on the cancer cell membrane bind TRAIL and cell surface enzymes clip the peptide thus release the drug onto the cell surface. Without the bulky TRAIL, the graphene strips with the embedded DOX are swallowed into the cells. The intracellular acidic environment promotes DOX's release from graphene. TRAIL on the cell surface triggers the apoptosis while DOX attacks the nucleus.

In the English language, medical terms generally have a regular morphology, often being compound words that comprise three kinds of morphemes: roots, prefixes, and suffixes. The etymology of medical terms often originates from Latin (particularly Neo-Latin) and Ancient Greek, with such medical terms being examples of neoclassical compounds. Each language may supply relevant morphemes for medical terms. For example, there are two primary roots for medical terminology relating to kidneys – one from Greek (νεφρός nephr(os)) and one from Latin (ren(es)). Lexical items of medical terminology, which forms part of international scientific vocabulary (ISV), are translingual (that is, being used across multiple languages). The use of ISV was a driving force in the development of the constructed language known as Interlingua. From the 1950s to late 1970s, a number of medical journals were published, or used, Interlingua.
1D-chiro-Inositol or D-chiro-inositol (often abbreviated DCI) is a chemical substance with formula C6H12O6, one of the nine isomers of cyclohexane-1,2,3,4,5,6-hexol (which may be collectively called "inositol"). The molecule has a ring of six carbon atoms, each bound to one hydrogen atom and one hydroxyl (OH) group. The hydroxyls on atoms 1, 2, and 4, in counterclockwise order, lie above the plane of the ring. The molecule being distinct from its mirror image, the compound is chiral, hence its name. Its enantiomer (mirror compound) is 1L-chiro-inositol. Compared to its more common isomer myo-inositol, DCI seems to have relatively minor roles in biochemistry and medicine, mostly connected to the biochemistry of insulin and other hormones.
They also included giving the Reserve Forces and Cadets Associations the power to produce an annual report to Parliament on the state of the volunteer reserves (the Royal Naval Reserve, The Royal Marines Reserve, the Army Reserve and the Royal Auxiliary Air Force). In January 2021, the Army Reserve trained strength stood at 26,820. (This figure excludes recruits undergoing phase 1 training and various non-deployable categories such as University Officers' Training Corps). During 2020, three reserve infantry battalions, 7 Rifles and 5 Fusiliers followed by 6 Rifles, provided the framework battalion for peacekeeping in Cyprus and over the winter 20/21 the Royal Yeomanry provided a composite squadron for a six-month tour on armoured reconnaissance as part of Britain's forward presence in Estonia. Army Reservists have a minimum commitment to serve 27 training days per year or 19 days for some national units. This period normally includes a two-week period of continuous training either as an Army Reserve unit, on courses or attached to a Regular unit. Army Reserve soldiers are paid at a similar rate to their regular equivalents while engaged on military activities.
The grouping consistent with transfer of nitrogenous groups is EC 2.6. This includes enzymes like transaminase (also known as "aminotransferase"), and a very small number of oximinotransferases and other nitrogen group transferring enzymes. EC 2.6 previously included amidinotransferase but it has since been reclassified as a subcategory of EC 2.1 (single-carbon transferring enzymes). In the case of aspartate transaminase, which can act on tyrosine, phenylalanine, and tryptophan, it reversibly transfers an amino group from one molecule to the other. The reaction, for example, follows the following order: L-aspartate +2-oxoglutarate
At 7:59 a.m., American Airlines Flight 11 took off from Logan International Airport in Boston. About fifteen minutes into the flight, five hijackers armed with boxcutters took over the plane, injuring at least three people and possibly killing one, before forcing their way into the cockpit. The terrorists also displayed an apparent explosive and sprayed mace into the cabin, to frighten the hostages into submission and further hinder resistance. Back at Logan, United Airlines Flight 175 took off at 8:14 a.m. Hundreds of miles southwest at Dulles International Airport, American Airlines Flight 77 left the runway at 8:20 a.m. Flight 175's journey proceeded normally for 28 minutes until 8:42 am, when a group of five hijacked the plane, murdering both pilots and stabbing several crew members before assuming control of the aircraft. These hijackers also used bomb threats to instill fear into the passengers and crew, also spraying "tear gas, pepper spray or another irritant" in the cabin to force passengers and flight attendants to the rear of the cabin. Concurrently, United Airlines Flight 93 departed from Newark International Airport in New Jersey; originally scheduled to pull away from the gate at 8:00 a.m., the plane was running 42 minutes late. At 8:46 a.m., Flight 11 was deliberately crashed into the north face of the World Trade Center's North Tower between the 93rd and 99th floors. The initial presumption by many was that it was an accident.

*fine chemicals merchant market size, growth potential Examples of applications in eight areas, ranging from adhesives to specialty polymers, are listed in Table 8. Overall, the attractiveness of the fine chemical industry is smaller than the life science industry. The total market, expressed in finished product sales, amounts to $150–200 billion, or about one fourth of the pharma market. The embedded fine chemicals account for an estimated $15 billion. Further disadvantages are the backward integration of the big players, e.g. Akzo-Nobel, Netherlands; Ajinomoto, Japan; Danone, France; Everlight Chemical Industrial Corp., Taiwan; Evonik-Degussa, Germany; Givaudan and Nestlé, Switzerland, Novozymes, Denmark, and Procter & Gamble, and Unilever USA. Innovation is based on new formulations of existing products, rather than the development of new fine chemicals. It is most likely to happen in application areas unrelated to human health, where NCEs are subject to very extensive testing.
=== Available forms === Buprenorphine/naloxone is available in sublingual formulations (that is, products that are dissolved under the tongue). It is also available through monthly injection by healthcare provider. There is no evidence that the tablet formulation is easier to divert and use in ways other than intended by the prescriber compared to the film formulation, or that the tablet formulation has a higher risk for accidental ingestion by children. There are various pharmacokinetic differences between sublingual formulations.
=== Clinical applications === Recombinant resilins have been studied for potential application in the fields of biomedical engineering and medicine. In particular, hydrogels composed of recombinant resilins have been used as tissue engineering scaffolds for mechanically-active tissues including cardiovascular, cartilage and vocal cord tissues. Early work has focused on optimizing the mechanical properties, chemistry and cytocompability of these materials, but some in vivo testing of resilin hydrogels has also been performed. Researchers at the University of Delaware and Purdue University have developed methods for creating elastic hydrogels composed of resilin that were compatible with stem cells and displayed similar rubber elasticity to that of natural resilin. Semi-synthetic resilin-based hydrogels, which incorporate poly(ethylene glycols), have also been reported.
Intermediate schools are referred to as "middle schools" in the PGCPS system, and operate as grades 6–8 middle schools. Grades 7–9 junior high school were phased out in the mid-1980s. Recent efforts have been made to convert most middle schools to the more popular grades 6–8 model. Issues in the past such as over-enrollment, lack of classroom space, and funding, had made it hard to convert all middle schools to a grades 6–8 configuration, but with increased funding and the addition of new middle schools, the transition is slowly being made, to be completed by the beginning of SY2024-2025. Most middle schools in Prince George's County operate with a "comprehensive" model, as their base. Most students are assigned to a middle school based on an "attendance area." Most magnet programs operate as a "School-Within-A-School" model, where the magnet serves as an alternative program, in addition to the main comprehensive program, and students from outside the regular attendance area of the middle school are enrolled and accepted into the magnet, either through "continuity" (automatic continuation from an elementary school magnet program to the middle school level equivalent) or more commonly, through a magnet lottery, where students apply for a magnet program and are granted acceptance through a random drawing. Almost all middle schools have a whole-school "Signature Program" that includes a specialized program of instruction which is the foundation of the school's comprehensive program.

It is designed as a triple agonist acting on the GLP-1, GIP, and glucagon receptors. This combination is intended to influence appetite, insulin secretion, and energy expenditure. Single-receptor and dual-receptor compounds act on a narrower set of targets.
No. It remains investigational, and phase 3 results have not been fully published or reviewed by regulators. Official approval status should be confirmed through regulatory agencies rather than secondary sources.
The added glucagon receptor activity is the main difference in its mechanism. Whether that addition produces meaningful benefits in clinical outcomes is still being studied. Comparisons between compounds rest largely on indirect rather than head-to-head trial data.
Retatrutide is an investigational peptide that activates the GLP-1, GIP, and glucagon receptors at the same time. It is being studied for obesity and type 2 diabetes and has not been approved for clinical use. The internal code LY3437943 refers to the same molecule.
