Retatrutide is an investigational peptide studied for obesity and type 2 diabetes. It is a single synthetic molecule designed to activate three metabolic receptors simultaneously. The compound belongs to the incretin mimetic family, a group of peptides that imitate gut hormones involved in appetite and glucose control. Its research code is LY3437943, and it remains under clinical study rather than cleared for routine medical use.
Acting as a triple agonist, the molecule binds the GLP-1, GIP, and glucagon receptors. GLP-1 activity slows gastric emptying and dampens appetite, while GIP signaling contributes to insulin sensitivity and fat metabolism. Glucagon receptor engagement raises energy expenditure and encourages fat breakdown, although it can also elevate blood glucose. Combining three pathways is intended to yield larger weight reduction than single or dual agonists, and researchers continue to examine how the balance among them shapes tolerability.
Clinical studies have reported notable reductions in body weight among participants. Early trials measured safety and explored several dose levels, and later studies tracked body-weight change over months of treatment. Investigators also monitor effects on glycemic markers, liver fat, and blood lipids. Because the compound is still in development, questions about long-term safety, cardiovascular outcomes, and durability after treatment ends remain open.
开发进程从早期单次和多次给药研究推进至大规模后期试验。公开报告显示，参与者在体重和相关代谢指标上出现变化，但完整数据需经同行评审并接受独立复核。试验设计通常包括随机、双盲和对照设置，以区分药物效应与行为干预。监管提交和标签范围尚未确定；长期维持效果与心血管结局仍是开放问题。
与仅靶向单一受体的同类药物相比，瑞他鲁肽增加胰高血糖素受体成分，理论上可提高能量消耗并改变脂肪分布。临床中观察到的体重变化是否主要来自该额外机制，目前尚无定论。胃肠道反应是该类药物常见不良事件，试验中通过剂量递增和监测进行管理。停药后体重反弹、个体差异和长期耐受性仍需更多数据。

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.
Published information places retatrutide in clinical development rather than on the market as an approved therapy. Early-stage and mid-stage trials have examined tolerability and changes in body weight, and larger studies continue to report results over time. Open questions include the durability of effects after treatment stops, the composition of weight lost, and cardiovascular outcomes over long periods. Statements about definitive benefit should therefore be treated as provisional. Regulatory status varies by jurisdiction and changes as applications are reviewed.
Retatrutide is an investigational synthetic peptide designed to activate three distinct receptor systems within a single molecule. Its pharmacological profile combines activity at the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor. This arrangement places it within a broader class of agents often described as multi-agonists, which contrast with compounds that engage one or two targets. Research interest centers on whether simultaneous signaling produces effects that single-receptor agonists cannot achieve alone. A single molecular entity also simplifies manufacturing and delivery logistics compared with combining separate agents.
One of the most worrisome characteristics of P. aeruginosa is its low antibiotic susceptibility, which is attributable to a concerted action of multidrug efflux pumps with chromosomally encoded antibiotic resistance genes, i.e., the genes that encode proteins that serve as enzymes to break down antibiotics. Examples of such genes are:
=== Among snakes === The question whether individual snakes are immune to their own venom has not yet been definitively settled, though an example is known of a cobra that self-envenomated, resulting in a large abscess requiring surgical intervention, but showing none of the other effects that would have proven rapidly lethal in prey species or humans. Furthermore, certain harmless species, such as the North American common kingsnake (Lampropeltis getula) and the Central and South American mussurana (Clelia spp.), are proof against the venom of the crotalines, which frequent the same districts, and which they are able to overpower and feed upon. The chicken snake (Spilotes pullatus) is the enemy of the fer-de-lance (Bothrops caribbaeus) in St. Lucia, and in their encounters, the chicken snake is invariably the victor. Repeated experiments have shown the European grass snake (Natrix natrix) not to be affected by the bite of the European adder (Vipera berus) and the European asp (Vipera aspis), this being due to the presence, in the blood of the harmless snake, of toxic principles secreted by the parotid and labial glands, and analogous to those of the venom of these vipers. Several North American species of rat snakes, as well as king snakes, have proven to be immune or highly resistant to the venom of rattlesnake species. The king cobra, which does prey on cobras, is said to be immune to their venom.
== Activity in wheat dough == Laccases have the potential to crosslink food polymers such as proteins and nonstarch polysaccharides in dough. In non-starch polysaccharides, such as arabinoxylans (AX), laccase catalyzes the oxidative gelation of feruloylated arabinoxylans by dimerization of their ferulic esters. These cross-links have been found to greatly increase the maximum resistance and decrease extensibility of the dough. The resistance was increased due to the crosslinking of AX via ferulic acid and resulting in a strong AX and gluten network. Although laccase is known to crosslink AX, under the microscope it was found that the laccase also acted on the flour proteins. Oxidation of the ferulic acid on AX to form ferulic acid radicals increased the oxidation rate of free SH groups on the gluten proteins and thus influenced the formation of S-S bonds between gluten polymers. Laccase is also able to oxidize peptide-bound tyrosine, but very poorly. Because of the increased strength of the dough, it showed irregular bubble formation during proofing. This was a result of the gas (carbon dioxide) becoming trapped within the crust so it could not diffuse out (like it would have normally) and causing abnormal pore size. Resistance and extensibility was a function of dosage, but at very high dosage the dough showed contradictory results: maximum resistance was reduced drastically. The high dosage may have caused extreme changes in the structure of dough, resulting in incomplete gluten formation.
Choi has formed a militant band consisting of former police officers who were expelled or faked their own deaths, who had helped Lee take the fall for an operation he led in 1995. He promises Lee not only the position of commissioner, but also of security secretary later on, upon which Lee gives into temptation and help his son. Despite this, Lee tries to convince Joe to leave Choi's team for his safety. Legislator Oswald Kan is convinced by his old friend and junior Edward Lai, the current secretary of justice, to participate in the public inquiry into Lau. He chastises Lau for his methods of "desperate times, desperate measures" and disagrees with the "Cold War" operation being a successful failure. During another hearing, Kan is taken aback when Lee openly criticizes Lau, rather than defending him initially. Kan and Lau deduce that Lee is being controlled, as Kan tells his one of his pupils, Bella Au, to investigate. Lau also asks Cheung and his independent team to monitor both Lee and Kan, who he finds suspicious as Kan did not sign up for the public hearing until deadline and likely changed his mind. Au decides to secretly follow Lee, and later Choi whom Lee confers with. Realizing that they are being followed in a tunnel, Choi orders his subordinate to crash into Au's car, causing a chain collision in which Au is killed, and Choi's car is trapped. Lau arrives to investigate, and a shoot-out occurs, in which Joe is shot and severely injured by Lau, but Choi escapes. Lee accosts Lau for failing to keep his promise of Joe's safety and nearly fight before Kan interferes.

=== European Union === Use of zinc pyrithione is prohibited within cosmetic products in the European Union since December 2021. The substance was considered safe for use in rinse-off and leave-in products of different tested concentrations, but due to potential environmental toxicity consideration of the use of zinc pyrithione was made against potential alternative substance ingredients. Due to no industry submission to the regulators supporting the continued use of zinc pyrithione and/or an absence of indications that there were no suitable alternatives to the substance: the use of zinc pyrithione became automatically prohibited within cosmetic products as an intended ingredient. This was as a consequence of zinc pyrithione addition to the Cosmetic Product Regulation (EC) No 1223/2009 Annex II list.
Cold Spring Tavern was established as a stagecoach stop in 1865. Originally known as the "Cold Spring Relay Station", it was a horse changeover and meals break station. The tavern is located 20 minutes north of Santa Barbara, California, in Cold Spring Canyon, which is about a mile off Highway 154 along Stagecoach Road (in the San Marcos Pass area).
CaCO3(s) + CO2(g) + H2O(l) → Ca(HCO3)2(aq) This reaction is important in the erosion of carbonate rock, forming caverns, and leads to hard water in many regions. An unusual form of calcium carbonate is the hexahydrate ikaite, CaCO3·6H2O. Ikaite is stable only below 8 °C.

Mixue Ice Cream & Tea (Chinese: 蜜雪冰城; pinyin: Mìxuě Bīngchéng; lit. 'honey snow ice city', ME-shweh) is a Chinese multinational restaurant chain specializing in ice cream and tea-based drinks. It was founded in 1997 in Zhengzhou by Zhang Hongchao. At the end of 2025, it operated almost 60,000 stores in China and overseas, making it the world's largest food-service chain by number of stores. Most locations are franchised and the company generates a large share of its revenue by supplying ingredients, equipment, and packaging to franchisees. Its menu emphasizes low-priced items such as soft-serve ice cream and milk tea. Mixue's parent company, Mixue Group, is listed on the Hong Kong Stock Exchange. The initial public offering raised about HK$3.45 billion (approximately US$444 million at the time) and the shares rose by about 40–47% on the first day of trading.

=== Legacy and claims of responsibility === Multiple claims of responsibility have continued to be put forward years after the recovery of the pumpkin. In 1999, editor-in-chief of the school paper Farhad Manjoo received an anonymous tip which potentially explained how the prank was carried out, involving a climb up the spire of the tower and the use of duct tape. The May 2000 Graduation issue of the Cornell Daily Sun stated that the prank was carried out by one Cornell student ringleader and two other Ithacan accomplices. In the Cornell Chimes Newsletter, it was stated that a student from the University of Montana, "Rob", confessed to former Head Chimesmaster Courtney Kimball that they had placed the pumpkin; Atlas Obscura deemed this inauthentic, though Cornell historian Ryan Earle stated that this was "the best source for how it happened." One rumor also claimed that the prankster's identity was passed down through each university archivist. In 2017, 20 years following the placement of the first pumpkin atop the tower, Manjoo, then reporter at The New York Times, called the event "the greatest prank in Cornell history" and that there was "no downside" in the pranksters coming forward as "all of that has passed now. Now they're just legends." Evan Fay Earle, the university archivist in 2017, stated that the pumpkin "continue[d] to generate interest at Cornell and [in] the community". The website about the pumpkin was partially brought back online for the anniversary.
== Recent writing == Recent articles about insulin coma treatment have attempted to explain why it was given such uncritical acceptance. In the US, Deborah Doroshow wrote that insulin coma therapy secured its foothold in psychiatry not because of scientific evidence or knowledge of any mechanism of therapeutic action, but due to the impressions it made on the minds of the medical practitioners within the local world in which it was administered and the dramatic recoveries observed in some patients. Today, she writes, those who were involved are often ashamed, recalling it as unscientific and inhumane. Administering insulin coma therapy made psychiatry seem a more legitimate medical field. Harold Bourne, who questioned the treatment at the time, said: "It meant that psychiatrists had something to do. It made them feel like real doctors instead of just institutional attendants". One retired psychiatrist who was interviewed by Doroshow "described being won over because his patients were so sick and alternative treatments did not exist". Doroshow argues that "psychiatrists used complications to exert their practical and intellectual expertise in a hospital setting" and that collective risk-taking established "especially tight bonds among unit staff members". She finds it ironic that psychiatrists "who were willing to take large therapeutic risks were extremely careful in their handling of adverse effects".
==== Fairness ==== Testosterone might encourage fair behavior. For one study, subjects took part in a behavioral experiment where the distribution of a real amount of money was decided. The rules allowed both fair and unfair offers. The negotiating partner could subsequently accept or decline the offer. The fairer the offer, the less probable a refusal by the negotiating partner. If no agreement was reached, neither party earned anything. Test subjects with an artificially enhanced testosterone level generally made better, fairer offers than those who received placebos, thus reducing the risk of a rejection of their offer to a minimum. Two later studies have empirically confirmed these results. However men with high testosterone were significantly 27% less generous in an ultimatum game. This additional information could suggest, contrarily, that testosterone may encourage greed or selfishness. Fairer offers from test subjects with higher testosterone in the original study increase the likeliness of the offer being accepted by the negotiating partner, therefore decreasing the probability of both participants leaving without any money.
US legislators expressed similar concerns, and bipartisan investigations were launched by the Senate and the House Armed Services Committees. On 17 December, the Senate passed the National Defense Authorization Act for Fiscal Year 2026 with a bipartisan amendment that, if passed by the House, would require Hegseth to provide unedited footage of the strikes and their authorizing orders to both committees or lose part of his travel budget.
== Examples == The unique interaction between the oligosaccharide chains have different applications. First, it aids in quality control by identifying misfolded proteins. The oligosaccharide chains also change the solubility and polarity of the proteins that they are bonded to. For example, if the oligosaccharide chains are negatively charged, with enough density around the protein, they can repulse proteolytic enzymes away from the bonded protein. The diversity in interactions lends itself to different types of glycoproteins with different structures and functions. One example of glycoproteins found in the body is mucins, which are secreted in the mucus of the respiratory and digestive tracts. The sugars when attached to mucins give them considerable water-holding capacity and also make them resistant to proteolysis by digestive enzymes. Glycoproteins are important for white blood cell recognition. Examples of glycoproteins in the immune system are:

It is a synthetic peptide classified as a triple receptor agonist. It engages the GLP-1, GIP, and glucagon receptors at once. It is investigated for metabolic and weight-related conditions rather than approved for general use.
No regulatory agency has approved it for routine medical use. It remains an investigational compound studied in controlled trials. Access outside research settings is not established.
Each receptor influences energy balance through different pathways. Combining them is intended to add fat loss from lowered intake and higher expenditure. The optimal balance among the three effects is still under study.
