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.
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.
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.

Development has progressed through early- and mid-stage human studies in adults with obesity and with type 2 diabetes. Published phase 2 data reported reductions in body weight and improvements in glycemic markers over the treatment period. No regulatory agency has approved the compound for any indication, and it remains available only within controlled research settings. Whether benefits observed in trials translate into durable outcomes after treatment stops is not yet established.
Retatrutide is an investigational synthetic peptide that acts as an agonist at three distinct G protein-coupled receptors. It combines activity at the glucagon-like peptide-1 receptor, the glucose-dependent insulinotropic polypeptide receptor, and the glucagon receptor within a single molecule. This multi-receptor profile distinguishes it from earlier incretin-based compounds that engage one or two of these pathways. Researchers designed the molecule to test whether simultaneous activation produces greater metabolic effects than single or dual agonism alone.
Pharmacologically the compound activates three receptors: GLP-1, GIP, and glucagon. GLP-1 and GIP signaling contribute to glucose-dependent insulin release, delayed gastric emptying, and reduced appetite, while glucagon receptor activation is associated with increased energy expenditure and hepatic fat oxidation. The single-molecule design is intended to keep these activities in one peptide rather than combining separate agents. Relative activity at each receptor differs, and the balance between them is a central question in interpretation. The glucagon component is partly offset by incretin-mediated insulin secretion, an interaction that remains incompletely characterized.
Development has progressed from single- and multiple-ascending-dose studies in healthy volunteers into larger randomized trials in adults with obesity, type 2 diabetes, and fatty liver disease. Early reports describe dose-dependent reductions in body weight and improvements in glycemic markers over treatment periods of several months. Whether the glucagon arm adds tolerability cost without added benefit is still debated. Long-term cardiovascular outcomes, effects after treatment stops, and performance in older or comorbid populations are open questions rather than settled findings. Approval status may change, so the current investigational label should be confirmed against regulatory sources.
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.
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.
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.
A selenenic acid is an organoselenium compound and an oxoacid with the general formula RSeOH, where R ≠ H. It is the first member of the family of organoselenium oxoacids, which also include seleninic acids and selenonic acids, which are RSeO2H and RSeO3H, respectively. Selenenic acids derived from selenoenzymes are thought to be responsible for the antioxidant activity of these enzymes. This functional group is called SeO-selenoperoxol in recent nomenclature.
With an older friend, Lloyd Simon, Pauling set up Palmon Laboratories in Simon's basement. They approached local dairies offering to perform butterfat samplings at cheap prices but dairymen were wary of trusting two boys with the task, and the business ended in failure. At age 15, the high school senior had enough credits to enter Oregon State University (OSU), known then as Oregon Agricultural College. Lacking two American history courses required for his high school diploma, Pauling asked the school principal if he could take the courses concurrently during the spring semester. Denied, he left Washington High School in June without a diploma. The school awarded him an honorary diploma 45 years later, after he was awarded two Nobel Prizes. Pauling held a number of jobs to earn money for his future college expenses, including working part-time at a grocery store for US$8 per week (equivalent to US$240 in 2025). His mother arranged an interview with the owner of a number of manufacturing plants in Portland, Mr. Schwietzerhoff, who hired him as an apprentice machinist at a salary of US$40 per month (equivalent to US$1,180 in 2025). This was soon raised to US$50 per month. Pauling also set up a photography laboratory with two friends. In September 1917, Pauling was finally admitted by Oregon State University. He immediately resigned from the machinist's job and informed his mother, who saw no point in a university education, of his plans.
Dunkin' Donuts LLC, doing business as Dunkin', is an American multinational fast food restaurant chain specializing in coffee and doughnuts. It was founded by Bill Rosenberg in Quincy, Massachusetts, in 1950. The chain was acquired by Baskin-Robbins' holding company Allied Lyons in 1990. Its acquisition of the Mister Donut chain and the conversion of that chain to Dunkin' Donuts facilitated the brand's growth in North America the same year. Dunkin' and Baskin-Robbins eventually became subsidiaries of Dunkin' Brands, headquartered in Canton, Massachusetts, in 2004. Dunkin' Brands was purchased by Inspire Brands on December 15, 2020. The chain began rebranding as a "beverage-led company", and was renamed Dunkin' in January 2019. While stores in the U.S. began using the new name, the company intends to roll out the rebranding to all of its international locations. With approximately 14,200 locations in 39 countries and $14.5 billion in system sales, Dunkin' is one of the largest coffee shop and doughnut shop chains in the world. In addition to several varieties of coffee and doughnuts, products sold include bagels, breakfast sandwiches, muffins, and doughnut holes branded as Munchkins.
The temperature at which dew forms on a clean surface is directly related to the vapor pressure of the air. Dew point hygrometers work by placing a mirror over a closed sample chamber. The mirror is cooled until the dew point temperature is measured by means of an optical sensor. This temperature is then used to find the relative humidity of the chamber using psychrometrics charts. This method is theoretically the most accurate (+/- 0.003 aw) and often the fastest. The sensor requires cleaning if debris accumulates on the mirror.

==== Sides are drawn ==== For the latter half of 2003; sides continued to be drawn in the feud as The Source magazine publicly showed support of Ja Rule's in the conflict. The magazine's co-owner at the time Raymond "Benzino" Scott took notice of the ongoing feud as he was involved in a separate public quarrel with Eminem, plausibly displaying his support for Ja Rule in a retaliatory act as Eminem had demonstrated full support for 50 Cent and G-Unit. The toll of the feud began to put itself on display for Ja Rule and Murder Inc by the latter half of 2003; the album Blood in My Eye was released on November 4, 2003 with a heavy emphasis on responding to the feud with both 50 Cent, G-Unit, and Eminem. Despite receiving mixed-to-positive reviews, Blood in My Eye failed to achieve a certification, selling a total of approximately 400,000 copies, indicative of the damage to Murder Inc's public image amidst the feud and their own legal issues with the federal government. Amidst the conflict, Ja Rule still had the support of various high-profile figures within the community, such as Fat Joe and Jadakiss who would go on to appear on Ja Rule's 2004 album R.U.L.E. in the form of the track New York. The album showed a slight return for Ja Rule commercially as it would outsell its predecessor and receive a gold certification, led by the success of New York as a single. The song continued to maintain tensions with 50 Cent and G-Unit as it was perceived to be a subliminal diss track against both 50 Cent and G-Unit member Lloyd Banks, mocking the latter's then-recent single "On Fire".
Donated blood is usually processed after collection to make it suitable for use in specific patient populations. Collected blood is then separated into blood components by centrifugation: red blood cells, plasma, and platelets. Plasma can be further processed to manufacture albumin protein, clotting factor concentrates, cryoprecipitate, fibrinogen concentrate, and immunoglobulins (antibodies). Red cells, plasma, and platelets can also be donated individually via a more complex process called apheresis. Different blood components require specific storage conditions: red blood cells are typically stored at 1–6 °C, platelets at 20–24 °C with continuous agitation, and plasma is stored frozen at −18 °C or lower to preserve clotting factors.

organised the Poor People's Campaign to address issues of economic and social justice while personally showing sympathy with democratic socialism. The classic Port Huron Statement of the Students for a Democratic Society combined a stringent critique of the Stalinist model with calls for a democratic socialist reconstruction of society. In reaction to the Tet Offensive, protests also sparked a broad movement in opposition to the Vietnam War all over the United States and even into London, Paris, Berlin and Rome. Mass socialist or communist movements grew not only in the United States, but also in most European countries. The most spectacular manifestation of this was the May 1968 protests in France in which students linked up with strikes of up to ten million workers and the movement seemed capable of overthrowing the government, albeit for only a few days. In many other capitalist countries, struggles against dictatorships, state repression and colonisation were also marked by protests in 1968 such as the beginning of the Troubles in Northern Ireland, the Tlatelolco massacre in Mexico City and the escalation of guerrilla warfare against the military dictatorship in Brazil. Countries governed by Marxist–Leninist parties had protests against bureaucratic and military elites. In Eastern Europe, there were widespread protests that escalated particularly in the Prague Spring in Czechoslovakia. In response, the Soviet Union occupied Czechoslovakia, but the occupation was denounced by the Italian and French communist parties as well as the Communist Party of Finland.
In Greece, the ancient Greek physician Hippocrates, the "father of modern medicine", laid the foundation for a rational approach to medicine. Hippocrates introduced the Hippocratic Oath for physicians, which is still relevant and in use today, and was the first to categorize illnesses as acute, chronic, endemic and epidemic, and use terms such as, "exacerbation, relapse, resolution, crisis, paroxysm, peak, and convalescence". The Greek physician Galen was also one of the greatest surgeons of the ancient world and performed many audacious operations, including brain and eye surgeries. After the fall of the Western Roman Empire and the onset of the Early Middle Ages, the Greek tradition of medicine went into decline in Western Europe, although it continued uninterrupted in the Eastern Roman (Byzantine) Empire. Most of our knowledge of ancient Hebrew medicine during the 1st millennium BC comes from the Torah, i.e. the Five Books of Moses, which contain various health related laws and rituals. The Hebrew contribution to the development of modern medicine started in the Byzantine Era, with the physician Asaph the Jew.
==== United States ==== Pentazocine was originally unclassified under the Controlled Substances Act in the United States. A petition was filed with the US Drug Enforcement Administration (DEA) on October 1, 1971, to shift it to Schedule III. The petition was filed by Joseph L. Fink III, a pharmacist and law student at Georgetown University Law Center as part of the course Lawyering in the Public Interest. That petition was accepted for review on November 10, 1971. The DEA published a Final Rule transferring it to Schedule IV on January 10, 1979, with an effective date of February 9, 1979. Pentazocine is still classified in Schedule IV under the Controlled Substances Act in the United States, even with the addition of naloxone. Some states classify it in Schedule II, such as Illinois and South Carolina (injectable form only), or Schedule III such as Kentucky.) Internationally, pentazocine is a Schedule III drug under the Convention on Psychotropic Substances, except in Canada where it is Schedule I under the federal Controlled Drugs and Substances Act. Pentazocine has a DEA ACSCN of 9720; being a Schedule IV substance, the DEA does not assign an annual manufacturing quota for pentazocine for the United States.
There are a variety of bioreactors designed for 3D cell cultures. There are small plastic cylindrical chambers, as well as glass chambers, with regulated internal humidity and moisture specifically engineered for the purpose of growing cells in three dimensions. The bioreactor uses bioactive synthetic materials such as polyethylene terephthalate membranes to surround the spheroid cells in an environment that maintains high levels of nutrients. They are easy to open and close, so that cell spheroids can be removed for testing, yet the chamber is able to maintain 100% humidity throughout. This humidity is important to achieve maximum cell growth and function. The bioreactor chamber is part of a larger device that rotates to ensure equal cell growth in each direction across three dimensions. QuinXell Technologies now under Quintech Life Sciences from Singapore has developed a bioreactor known as the TisXell Biaxial Bioreactor which is specially designed for the purpose of tissue engineering. It is the first bioreactor in the world to have a spherical glass chamber with biaxial rotation; specifically to mimic the rotation of the fetus in the womb; which provides a conducive environment for the growth of tissues. Multiple forms of mechanical stimulation have also been combined into a single bioreactor. Using gene expression analysis, one academic study found that applying a combination of cyclic strain and ultrasound stimulation to pre-osteoblast cells in a bioreactor accelerated matrix maturation and differentiation.

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.
It is an investigational peptide that activates three hormone receptors: GIP, GLP-1 and glucagon. It is being studied mainly for obesity and type 2 diabetes, and it is not approved for any clinical use. Published information comes from controlled trials rather than from general practice.
