Tesamorelin is a synthetic peptide that acts as an analog of growth hormone-releasing hormone, a natural hypothalamic signal. Its sequence corresponds to the forty-four amino acid form of the human hormone, with a small acyl group attached near the amino terminus. That modification slows enzymatic breakdown and extends the time the peptide remains active in circulation. The compound was developed as a pharmacological way to raise endogenous growth hormone output rather than supplying the hormone directly.
After injection, the peptide binds receptors on somatotroph cells in the anterior pituitary. Receptor activation raises intracellular cyclic AMP and triggers release of stored growth hormone into the bloodstream. Because the compound works through the body's own regulatory system, growth hormone pulses retain much of their normal feedback control. Repeated administration also raises insulin-like growth factor 1, a hormone produced mainly in the liver. Investigators treat that rise as a marker that the pituitary axis has been engaged.
Interest in this peptide developed because native GHRH has a short circulating lifetime. The N-terminal modification slows cleavage by dipeptidyl peptidase IV, an enzyme that removes the first two residues of many peptides and terminates their activity. Slower degradation means a longer window of receptor stimulation per administration. This design logic parallels other modified peptide hormones, where a small chemical change at a vulnerable site yields a more durable molecule without altering the core mechanism of action.
The peptide is synthesized chemically rather than extracted from biological sources. Solid-phase synthesis builds the chain from the C-terminus toward the N-terminus, after which the hexenoyl group is attached. Purity is typically assessed by high-performance liquid chromatography, and identity is confirmed by mass spectrometry. Regulatory review of the finished product focuses on these analytical controls, since small deviations in sequence or modification can change biological activity. Questions about long-term effects on the pituitary axis remain areas of continued investigation.
Tesamorelin is a synthetic peptide that belongs to the growth hormone-releasing hormone (GHRH) family. Its sequence corresponds to the fully active 44-amino-acid form of human GHRH, with a single structural modification: the addition of a trans-3-hexenoyl group at the N-terminus. That modification is not found in the naturally occurring hormone and was introduced deliberately during development to improve stability against enzymatic degradation. The compound is therefore best described as a stabilized analogue rather than a naturally occurring peptide.

Several related peptides act on the same receptor, including sermorelin, a shorter GHRH fragment, and modified analogs such as CJC-1295 and modified GRF(1-29) that are common in research settings rather than approved products. Tesamorelin differs from growth hormone itself in that it acts upstream, prompting the pituitary to release the hormone through physiological signaling rather than supplying it directly. Terminology in the literature distinguishes GHRH analogs, growth hormone secretagogues, and recombinant growth hormone, although popular discussion often blurs these categories together. Precise naming matters when comparing study results.
Tesamorelin is a synthetic peptide of 44 amino acids that reproduces the sequence of human growth hormone-releasing hormone (GHRH) and carries a trans-3-hexenoyl group on its N-terminal tyrosine. That small fatty-acid modification blocks cleavage by dipeptidyl peptidase-4, the enzyme that rapidly degrades native GHRH in plasma. The result is a molecule with a longer circulating half-life than the natural hormone while retaining the same receptor target. It is supplied as a lyophilized powder for reconstitution and belongs to the broader class of GHRH analogs studied for effects on pituitary growth hormone secretion.
Development work on the compound, originally designated TH9507, focused on conditions in which reduced growth hormone signaling is thought to contribute to altered body composition. The United States Food and Drug Administration approved it in 2010 for the treatment of excess visceral abdominal fat in adults with human immunodeficiency virus infection and lipodystrophy. Later research examined other populations, including adults with mild cognitive impairment, where a large trial did not meet its primary endpoints. This mixed record illustrates how a single mechanism can produce clear effects in one setting and inconclusive results in another.
Several compounds share the GHRH framework, including sermorelin, the shorter 1-29 fragment, and other analogs built on the full 1-44 chain. Naming follows a common convention: a stem that identifies the peptide plus a suffix marking analog status. Reports may describe tesamorelin by its sequence fragment, as a GHRH(1-44) analog, or by its amino-terminal modification. Indexing the compound therefore requires searching all of these forms, since some older literature predates the current international nonproprietary name.
Tesamorelin is a synthetic peptide built from 44 amino acids and classified with the growth hormone–releasing hormone family. Its sequence corresponds to the human GHRH(1-44) backbone, carrying one structural change at the amino terminus. That change is a trans-3-hexenoyl group placed where the natural peptide would have an unmodified end. The modification is the feature that separates the compound from the endogenous hormone in name, in stability, and in how it is handled in the laboratory.
Clinical interest in tesamorelin arose from the need to address visceral adiposity in people living with HIV. Antiretroviral therapy improved survival but was associated in some patients with central fat accumulation, altered lipid profiles, and metabolic complications. This condition, often called HIV-associated lipodystrophy, involves excess visceral adipose tissue that is difficult to manage through diet and exercise alone. Investigators evaluated tesamorelin because GHRH analogs can stimulate growth hormone secretion and influence fat distribution without direct liposuction or invasive procedures.
A Phase 3 program led to regulatory approval in the United States in 2010 for reduction of excess visceral abdominal fat in adults with HIV and lipodystrophy. Subsequent studies examined effects on liver fat, muscle area, and metabolic markers, with mixed findings for some endpoints. Long-term cardiovascular outcomes and effects on mortality remain uncertain because most trials were relatively short and focused on imaging-based fat measurements. Use in populations without HIV has been studied experimentally but is not part of the approved indication.
Tesamorelin is a synthetic analog of growth hormone-releasing hormone, a peptide hormone produced by the hypothalamus. The molecule retains the 44-amino-acid sequence of human GHRH and carries a trans-3-hexenoyl modification at its N-terminus. This modification increases resistance to enzymatic degradation and extends the peptide's functional stability relative to native GHRH. The compound is supplied as a lyophilized powder for reconstitution and subcutaneous administration in clinical settings. Its development code was TH9507, and it belongs to the GHRH analog class. It is not a growth hormone product; instead, it acts upstream to stimulate endogenous growth hormone release.
Tesamorelin is a synthetic peptide of forty-four amino acids whose sequence reproduces human growth hormone-releasing hormone. Its distinguishing feature sits at the amino terminus, where a trans-3-hexenoyl group replaces the free amine. That acylation slows cleavage by dipeptidyl peptidase IV, an enzyme that otherwise removes the first two residues and inactivates the natural hormone quickly. The modified peptide therefore persists longer in circulation while keeping the same receptor target. It is handled as a lyophilized solid and dissolved shortly before use.
Signaling begins at the GHRH receptor, a class B G protein-coupled receptor displayed on somatotroph cells of the anterior pituitary. Receptor occupancy activates Gs proteins, which raise adenylyl cyclase activity and intracellular cyclic AMP, in turn driving protein kinase A dependent pathways. The downstream output is synthesis and pulsatile secretion of growth hormone into the bloodstream. Hepatic tissue and peripheral sites respond by increasing insulin-like growth factor 1 production. Somatostatin and IGF-1 itself supply negative feedback that caps the size and duration of each secretory burst.
According to the Panel of Experts on Yemen established pursuant to Security Council resolution 2140, the Houthis have carried out a wide range of human rights violations, including violations of international humanitarian law and abuse of women and children. Children as young as 13 have been arrested for "indecent acts" for alleged homosexual orientation or "political cases" when their families do not comply with Houthi ideology or regulations. Minors share cells with adult prisoners, and according to unspecified reports that the Panel has deemed "credible", boys held in Al-Shahid Al-Ahmar police station in Sana'a are systematically raped. Aside from the Panel of Experts, London-based Arabic newspaper Asharq Al-Awsat alleges that the Houthis have revived slavery in Yemen.

== Chemistry == Dextromoramide is the right-handed isomer of the moramide molecule. The left-handed molecule is called levomoramide, and a mixture of the two is called racemoramide. Its full chemical name is (+)-1-(3-Methyl-4-morpholino-2,2-diphenylbutyryl)pyrrolidine, and its molecular formula: C25H32N2O2, with an atomic weight of ~392.5. Dextromoramide was discovered during the course of research into a related family of compounds, the α,α-Diphenyl-γ-Dialkyamino-Butyramides, which show no analgesic activity, but are extremely active physiologically as inhibitors of gastric secretions in man. Other drugs from this series show antispasmodic and antihistamine effects, but most research was put into researching analgesics. The structure-activity relationships of this family of drugs was investigated extensively, with dextromoramide representing the optimisation of several different structural features; (i) at the 1-amide group only the pyrrolidine and dimethylamide substituents were active, with pyrrolidine being more potent (ii) the alkyl chain was more potent when methylated, 3-methylation was more potent than 4-methylation, and in the 3-methyl analogues the dextro isomer was more active (iii) while morpholine, dimethylamine, pyrrolidine and piperidine were all active at the 4-amine group, morpholine was the most active (iv) any substitution on the phenyl rings reduces activity.
== History == Willis Carrier, a mechanical engineer working for Buffalo Forge, is credited with inventing modern air conditioning in July 1902. In 1908, the Carrier Air Conditioner Company of America was created as a subsidiary of the Buffalo Forge Company, with Willis Carrier as its vice president. With the onset of World War I in late 1914, the Buffalo Forge Company, where Carrier had been employed for 12 years, decided to confine its activities entirely to manufacturing. The result was that in 1915, Carrier and six other engineers pooled $32,600 to form the Carrier Engineering Corporation. They purchased their first factory in 1920, in Newark, New Jersey. The very next year, Carrier solved a problem that had vexed the Islington Studios (owned by Famous Players–Lasky and then Paramount Pictures) in London -- thick fog coming into the stage set and suspending filming. A pressurized system that cooled air at a rate of "3,500,000 gallons per hour" and then delivered the dehumidified air at the temperature set by a thermostat, kept the interior air clear and camera-ready. In 1955, Carrier merged with Affiliated Gas Equipment, Inc., which owned the Bryant Heater Co., Day & Night Water Heater Co., and Payne Furnace & Supply Co. Carrier Corporation was acquired by United Technologies Corporation (UTC) in July 1979. Prior to the acquisition by UTC, Carrier Corporation was known as the Carrier Air Conditioning Company. International Comfort Products (ICP), headquartered in Lewisburg, Tennessee, was acquired by Carrier in 1999.

Recent genomic and phylogenomic approaches have significantly clarified plastid genome evolution, the horizontal movement of endosymbiont genes to the "host" nuclear genome, and plastid spread throughout the eukaryotic tree of life. It is accepted that both euglenophytes and chlorarachniophytes obtained their chloroplasts from chlorophytes that became endosymbionts. In particular, euglenophyte chloroplasts share the most resemblance with the genus Pyramimonas. However, there is still no clear order in which the secondary and tertiary endosymbioses occurred for the "chromist" lineages (ochrophytes, cryptophytes, haptophytes and myzozoans). Two main models have been proposed to explain the order, both of which agree that cryptophytes obtained their chloroplasts from red algae. One model, hypothesized in 2014 by John W. Stiller and coauthors, suggests that a cryptophyte became the plastid of ochrophytes, which in turn became the plastid of myzozoans and haptophytes. The other model, suggested by Andrzej Bodył and coauthors in 2009, describes that a cryptophyte became the plastid of both haptophytes and ochrophytes, and it is a haptophyte that became the plastid of myzozoans instead. In 2024, a third model by Filip Pietluch and coauthors proposed that there were two independent endosymbioses with red algae: one that originated the cryptophyte plastids (as in the previous models), and subsequently the haptophyte plastids; and another that originated the ochrophyte plastids, where the myzozoans obtained theirs.
==== Competitive assays ==== Competitive assays are generally used for smaller analytes since smaller analytes have fewer binding sites. The sample first encounters antibodies to the target analyte labelled with a visual tag (colored particles). The test line contains the target analyte fixed to the surface. When the target analyte is absent from the sample, unbound antibody will bind to these fixed analyte molecules, meaning that a visual marker will show. Conversely, when the target analyte is present in the sample, it binds to the antibodies to prevent them binding to the fixed analyte in the test line, and thus no visual marker shows. This differs from sandwich assays in that no band means the analyte is present.

=== Prosecution === In his opening statement, prosecutor Brian Leveson portrayed the Wests as sadistic sex-obsessed murderers, terming the bodies discovered at Cromwell Street and Midland Road "secrets more terrible than words can express ... [The victims'] last moments on earth were as objects of the sexual depravity of this woman and her husband." He pointed out that Fred had been incarcerated when Charmaine was killed, claimed that Fred and Rose had each learned from their mistake in allowing Owens to live, and said that the gag on victim Thérèse Siegenthaler evinced a "feminine" touch—a scarf tied in a bow. Leveson promised to demonstrate Rose's controlling and sexually sadistic character, as well as her efforts to deflect suspicion about the disappearance of their victims. Prosecution witnesses included Cromwell Street lodgers, victims' relatives, Rose's mother, Daisy, and sister, Glenys, and surviving victims including Kathryn Halliday (a former lover of Fred and Rose), Owens, Anne Marie and a "Miss A" (who had been sexually assaulted at age 14 by Fred and Rose in 1977 and who described Rose as the more aggressive perpetrator of the two). Neighbours described Charmaine's 1971 disappearance while Fred was imprisoned and Rose's casual indifference to Heather's disappearance. Rose's counsel, Dick Ferguson, tried to discredit prosecution witnesses as either having financially exploited their connection to the case or being motivated by grudges.
=== Fossil record === The earliest widely accepted animal fossils are rather modern-looking cnidarians, possibly from around 580 million years ago, although fossils from the Doushantuo Formation can only be dated approximately. The identification of some of these as embryos of animals has been contested, but other fossils from these rocks strongly resemble tubes and other mineralized structures made by corals. Their presence implies that the cnidarian and bilaterian lineages had already diverged. Although the Ediacaran fossil Charnia used to be classified as a jellyfish or sea pen, more recent study of growth patterns in Charnia and modern cnidarians has cast doubt on this hypothesis, leaving the Canadian polyp Haootia and the British Auroralumina as the only recognized cnidarian body fossils from the Ediacaran. Auroralumina is the earliest known animal predator. Few fossils of cnidarians without mineralized skeletons are known from more recent rocks, except in Lagerstätten that preserved soft-bodied animals. A few mineralized fossils that resemble corals have been found in rocks from the Cambrian period, and corals diversified in the Early Ordovician. These corals, which were wiped out in the Permian–Triassic extinction event about 252 million years ago, did not dominate reef construction since sponges and algae also played a major part. During the Mesozoic era, rudist bivalves were the main reef-builders, but they were wiped out in the Cretaceous–Paleogene extinction event 66 million years ago, and since then the main reef-builders have been scleractinian corals.

=== Plot === Opposing Force opens with Shephard riding on a V-22 Osprey with his squad. His squad discuss their deployment, somewhat irritated that they have not been told what they are being deployed for. However, as they are nearing their landing zone at Black Mesa, airborne alien creatures attack the Osprey formation, causing Shephard's Osprey to crash land. Shephard regains consciousness in a Black Mesa medical bay, tended to by the science team, learning that the Marines are being steadily beaten by the alien forces from Xen and orders have come through to pull out. Consequently, Shephard departs to reach an extraction point and escape the facility. However, Shephard is prevented from reaching the extraction point by the enigmatic G-Man, resulting in the evacuation craft leaving without him. Other Marines who have also been left behind team up with Shephard and attempt to reach another extraction point near Black Mesa's Lambda Complex, but en route they come under attack from black operations units seeking to thoroughly contain the situation and eliminate all survivors. Shephard makes it to the Lambda Complex alive, and briefly sees Gordon Freeman as the latter teleports to Xen in the final stages of Half-Life. To escape the teleportation chamber, Shephard is forced to enter a separate portal, briefly taking him to Xen before depositing him in an entirely different area of the facility.
The finding that plants which lack the receptor of karrikin receptor show several developmental phenotypes (enhanced biomass accumulation and increased sensitivity to drought) have led some to speculate on the existence of an as yet unidentified karrikin-like endogenous hormone in plants. The cellular karrikin signalling pathway shares many components with the strigolactone signalling pathway. Triacontanol – a fatty alcohol that acts as a growth stimulant, especially initiating new basal breaks in the rose family. It is found in alfalfa (lucerne), bee's wax, and some waxy leaf cuticles.

Another film purported to have been the highest-grosser is the 1972 pornographic film Deep Throat. In 1984, Linda Lovelace testified to a United States Senate Judiciary Subcommittee on juvenile justice that the film had earned $600 million; this figure has been the subject of much speculation, since if it is accurate then the film would have made more money than Star Wars, and finished the 1970s as the highest-grossing film. The main argument against this figure is that it simply did not have a wide enough release to sustain the sort of sums that would be required for it to ultimately gross this amount. Exact figures are not known, but testimony in a federal trial in 1976—about four years into the film's release—showed the film had grossed over $25 million. Roger Ebert has reasoned it possibly did earn as much as $600 million on paper, since mobsters owned most of the adult movie theaters during this period and would launder income from drugs and prostitution through them, so probably inflated the box-office receipts for the film. The Birth of a Nation, Gone with the Wind, The Godfather, Jaws, Star Wars, E.T., and Avatar all increased their record grosses with re-releases. The grosses from their original theatrical runs are included here along with totals from re-releases up to the point that they lost the record; therefore the total for The Birth of a Nation includes income from its reissues up to 1940; the total for Star Wars includes revenue from the late 1970s and early 1980s reissues but not from the 1997 Special Edition; the total for E.T.

It is a laboratory-made peptide that mimics growth hormone-releasing hormone. It prompts the pituitary gland to release growth hormone and has been studied mainly in adults with HIV-associated lipodystrophy.
Administered growth hormone supplies the hormone directly, while this peptide acts upstream by prompting the pituitary to release it. The indirect route preserves pulsatile secretion and some endogenous feedback, which changes the hormone and IGF-1 profile observed after treatment.
Reductions in visceral adipose tissue appear consistently in randomized trials of the approved population. Effects on peripheral fat, cardiovascular outcomes, and use outside that population are less well established.
It shares the 44-residue sequence of human GHRH but carries an added trans-3-hexenoyl group at its N-terminus. That addition does not occur in the natural hormone and serves mainly to resist enzymatic breakdown. The receptor target and signaling pathway remain the same.
