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.
The three-receptor design places retatrutide in a distinct category relative to older incretin-based therapies. Single agonists target one receptor, and dual agonists target two. Adding a third target broadens the pharmacological footprint and introduces new trade-offs among efficacy, tolerability, and glucose control. How these trade-offs resolve in large trials is a central focus of current research.
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, 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.
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.

Nicotine in tobacco can form carcinogenic tobacco-specific nitrosamines through a nitrosation reaction. This occurs mostly in the curing and processing of tobacco. Nicotine in the mouth and stomach can react to form N-nitrosonornicotine, a type 1 carcinogen, suggesting that oral consumption of non-tobacco forms of nicotine, such as nicotine gum, may be carcinogenic.
=== Osteoarthritis === Tentative evidence supports the use of PRP in osteoarthritis of the knee. A 2019 meta-analysis found that PRP might be more effective in reducing pain and improving function than hyaluronic acid in knee arthritis. This therapeutic effect is not only considered to be dependent on the concentration of growth factors but also on the presence of plasma clotting factors which can help to regulate inflammation and joint tissue regeneration.
=== Solution === Many growers resorted to their own methods in attempt to resolve the issue. Chemicals and pesticides were used to no avail. In desperation, some growers positioned toads under each vine, and others allowed their poultry to roam free in the hope they would eat the insects. None of these methods were successful. After Charles Valentine Riley, Missouri's state entomologist, confirmed Planchon's theory, Leo Laliman and Gaston Bazille, two French wine growers, both suggested the possibility that if vinifera vines could be combined, by means of grafting, with the aphid-resistant American vines, then the problem might be solved. Thomas Volney Munson was consulted and provided native Texan rootstocks for grafting. Because of Munson's role, the French government in 1888 sent a delegation to Denison, Texas, to confer on him the French Legion of Honor Chevalier du Mérite Agricole. Another viticulturist, Hermann Jaeger of Neosho, Missouri, was pivotal in the rescue of the French vineyards, as well. Jaeger working with the Missouri state entomologist George Hussman, had already raised vines with resistance to the pest. Indeed, several of the rootstalk varietals T.V. Munson had developed in Texas (Mrs Munson, Muench, and Neva Munson) were grafts with the hardy Neosho hybrids Jaeger had developed in Missouri. Jaeger exported 17 boxcars of his resistant rootstock to France.
Neanderthals, nonetheless, were frequently victims of animal attacks. There are multiple instances of Neanderthals practicing cannibalism, though it may have only been done in times of extreme food shortages, as in some cases in recorded human history.
=== Classification === The relationship of ginkgo to other plant groups remains uncertain. It has been placed loosely in the divisions Spermatophyta and Pinophyta, but no consensus has been reached. Since its seeds are not protected by an ovary wall, it can morphologically be considered a gymnosperm. The apricot-like structures produced by female ginkgo trees are technically not fruits, but are seeds that have a shell consisting of a soft and fleshy section (the sarcotesta), and a hard section (the sclerotesta). The sarcotesta has a strong smell that most people find unpleasant. The ginkgo is classified in its own division, the Ginkgophyta, comprising the single class Ginkgoopsida, order Ginkgoales, family Ginkgoaceae, genus Ginkgo and is the only extant species within this group. It is one of the best-known examples of a living fossil, because Ginkgoales other than G. biloba are not known from the fossil record after the Pliocene.

Aila Inkeri Keto AO (born 14 March 1943) is an Australian environmentalist. She is the founder and President of the Rainforest Conservation Society in Queensland, Australia, now known as the Australian Rainforest Conservation Society. In 2005, Keto was a recipient of the Queensland Greats Awards. Born in Tully, Queensland, Australia, to parents of Finnish origin, Dr Keto originally studied biochemistry and worked at the University of Queensland. In 1992, Keto received the IUCN Fred M. Packard Award in recognition of "outstanding service to protected and conserved areas" and in 1994 she was awarded an Officer of the Order of Australia for “service to conservation, particularly through promoting the protection and management of the wet tropical rainforests of Queensland”. She was nominated as Queenslander of the Year in 2000 and in 2001 she was awarded a Centenary Medal, "for service as an expert on wet tropics and as a leading conservationist and academic". In 2005, Dr Keto was awarded the Volvo Environment Prize for her work which, led to the protection of more than 15,000 square kilometres (5,800 sq mi) of Queensland's rainforest. This is only one of a series of awards that have been given to her for her environmental and conservation work which has resulted in three successful nominations for world heritage status: Wet Tropics, Fraser Island and the Central Eastern Rainforest Reserves of Australia (now Gondwana Rainforests of Australia).
Many described the separation from family members as excruciating, with some children being unable to talk to their parents, living with relatives in Gaza or having to monitor and parent younger siblings while their parents care for their injured siblings. On 16 August 2025, the U.S. State Department announced that it had suspended the issuance of visitor visas to people from the Gaza Strip, including children who require urgent medical care. In January–April 2024, medical evacuations for children from Gaza averaged about 296 per month; by late 2024 the rate had fallen to under one per day. In October 2024, UNICEF said children were dying not only from the violence itself but also because survivors were often unable to leave Gaza for urgent, life-saving treatment. By July/September 2025, an estimated 2,500-4,500 of critically wounded children are waiting for permits to be evacuated for care.
== Gingival fibers and periodontitis == In theory, gingival fibers are the protectors against periodontitis, as once they are breached, they cannot be regenerated. When destroyed, the gingival sulcus (labelled G in the diagram) increases in depth apically, allowing more debris and bacteria to remain in intimate contact with the delicate sulcular and junctional epithelia for longer times.
As muscle cells die, they absorb sodium, water, and calcium; the rhabdomyolysis releases potassium, myoglobin, phosphate, thromboplastin, creatine, and creatine kinase. Crush syndrome can directly come from compartment syndrome, if the injury is left untreated. Symptoms include the 5 Ps: pain, pallor, paresthesias (pins and needles), paralysis, and pulselessness.

The thymus increases in size from birth in response to postnatal antigen stimulation. It is most active during the neonatal and pre-adolescent periods. The thymus is located between the inferior neck and the superior thorax. During adolescence, the thymus begins to atrophy and regress, with adipose tissue mostly replacing the thymic stroma. However, residual T cell lymphopoiesis continues throughout adulthood, providing some immune response. The thymus is where the T lymphocytes mature and become immunocompetent. The absence of the thymus (whether congenital or due to loss of the thymus gland) results in severe immunodeficiency and subsequent high susceptibility to infection. In most species, the thymus consists of lobules divided by septa. These are composed of epithelium. T cells mature from thymocytes, proliferate, and undergo a selection process in the thymic cortex before entering the medulla to interact with epithelial cells. Research on bony fish showed a buildup of T cells in the thymus and spleen of lymphoid tissues in salmon and showed that there are not many T cells in non-lymphoid tissues. The thymus provides an inductive environment for developing T cells from hematopoietic progenitor cells. In addition, thymic stromal cells facilitate the selection of a functional and self-tolerant T cell repertoire. Therefore, one of the most important roles of the thymus is the induction of central tolerance. However, the thymus is not where the infection is fought, as the T cells have yet to become immunocompetent.
=== Classification === Classification of personality disorders differs significantly between the two most prominent frameworks for classification of mental disorders, namely: the Diagnostic and Statistical Manual of Mental Disorders and the International Classification of Diseases, the most recent editions of which are the DSM-5-TR and ICD-11, respectively. While personality disorders, including BPD, are diagnosed as separate entities in the DSM-5; in the ICD-11 classification of personality disorders, they are assessed in terms of severity levels, with trait and pattern specifiers serving to characterize the particular style of pathology. There is also a hybrid model, called the Alternative DSM-5 model for personality disorders, which defines BPD and five other PDs through disorder-specific combinations of pathological traits and areas of overall impairment.
At rates of use at that time (72 million SCM per year in the U.S.; see pie chart below) this would have been enough helium for about 58 years of U.S. use, and less than this (perhaps 80% of the time) at world use rates, although factors in saving and processing impact effective reserve numbers. Helium is commercially available in either liquid or gaseous form. As a liquid, it can be supplied in small insulated containers called dewars which hold as much as one cubic metre (1,000 L) of helium, or in large ISO containers, which have nominal capacities as large as 42 m3 (around 11,000 U.S. gallons). In gaseous form, small quantities of helium are supplied in high-pressure cylinders holding as much as 8 m3 (approximately .282 standard cubic feet), while large quantities of high-pressure gas are supplied in tube trailers, which have capacities of as much as 4,860 m3 (approx. 172,000 standard cubic feet).

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.
Retatrutide is an investigational synthetic peptide that activates three metabolic receptors: GLP-1, GIP, and glucagon. It is being studied for obesity and type 2 diabetes. It has not been approved for clinical use.
