A practical reference on visceral adipose tissue: what it is, how it behaves, what the literature reports, and where the honest uncertainties sit.
Reviewed 2026-03-14. Anything still debated is marked as such rather than presented as settled.
Clinical study of tesamorelin has centered on adults with HIV-associated lipodystrophy, a condition in which abdominal fat accumulates while peripheral fat is lost. In controlled trials, treated participants showed reductions in visceral adipose tissue measured by imaging, alongside modest shifts in some lipid values. Effects on subcutaneous fat were smaller and less consistent across studies. Whether these changes translate into fewer cardiovascular events remains an open question, because the trials were not designed or powered to answer it.
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.
Regulatory approval in the United States came in 2010, when the Food and Drug Administration cleared the peptide for the reduction of excess abdominal fat in adults with HIV infection and associated lipodystrophy. The decision rested mainly on two randomized phase 3 trials that enrolled roughly eight hundred patients and ran for twenty-six weeks. Participants receiving active drug showed substantially greater declines in visceral adipose tissue than those receiving placebo, while total body weight changed comparatively little. A reformulated presentation was later approved, and the product has remained a niche therapy rather than a general weight-loss agent.
Tesamorelin occupies a narrow position among agents that act on the growth hormone axis. Unlike growth hormone itself, which is given as replacement, it stimulates the pituitary to release the hormone in pulses, so the downstream increase in insulin-like growth factor 1 depends on intact somatotroph function. Other peptides in the same family include shorter GHRH fragments and synthetic secretagogues with different stability profiles. Several points remain unresolved, including whether the reduction in visceral fat translates into fewer cardiovascular events, what happens to metabolic markers after long-term use, and how the drug compares with lifestyle or surgical approaches.
Tesamorelin is a synthetic peptide that belongs to the growth hormone-releasing hormone family and contains the same forty-four amino acid sequence as endogenous GHRH, extended at the amino terminus by a trans-3-hexenoyl group. That small fatty acid modification protects the peptide from rapid cleavage by dipeptidyl peptidase-4, the enzyme that shortens the half-life of native GHRH to only a few minutes. Chemically the compound is produced by solid-phase peptide synthesis, purified by chromatography, and supplied as a sterile lyophilized powder for reconstitution.

A documented effect of tesamorelin is a reduction in visceral adipose tissue in some study populations. Researchers have reported decreases in trunk fat measured by computed tomography alongside changes in lipid markers. The mechanism is thought to involve growth hormone-mediated lipolysis, though the precise contribution of direct versus indirect pathways is not fully resolved. Studies have generally examined defined groups over finite periods, so long-term outcomes are less well characterized. Findings have not been uniform across all trials.
Tesamorelin is a synthetic peptide analog of growth hormone-releasing hormone (GHRH). Its sequence corresponds to the 44-amino-acid form of human GHRH with a trans-3-hexenoyl group attached to the N-terminal tyrosine. This modification slows enzymatic cleavage and extends the peptide's activity relative to the native hormone. The compound is produced by solid-phase peptide synthesis and supplied as a lyophilized powder. Researchers classify it as a GHRH receptor agonist. Its structure places it in the same family as other growth hormone secretagogues that act on the pituitary.
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.
==== Herpetology ==== Reptiles need UV‑B for biosynthesis of vitamin D, and other metabolic processes. Specifically cholecalciferol (vitamin D3), which is needed for basic cellular / neural functioning as well as the utilization of calcium for bone and egg production. The UV‑A wavelength is also visible to many reptiles and might play a significant role in their ability survive in the wild as well as in visual communication between individuals. Therefore, in a typical reptile enclosure, a fluorescent UV‑A / UV‑B source (at the proper spectrum strength and coverage for the species), must be available for many captive species to survive. Simple supplementation with cholecalciferol (vitamin D3) will not be enough as there is a complete biosynthetic pathway that is metabolically "leap-frogged" (risks of possible overdoses), the intermediate molecules and metabolites also play important functions in the animals health. Natural sunlight in the right levels is always going to be superior to artificial sources, but this might not be possible for keepers in different parts of the world. It is a known problem that high levels of output of the UV‑A part of the spectrum can both cause cellular and DNA damage to sensitive parts of their bodies – especially the eyes where blindness is the result of improper UV‑A and UV‑B source placement and use (an overdose is called photokeratitis). For many keepers there must also be a provision for an adequate heat source this has resulted in the marketing of heat and light "combination" products.
In 2024, D'Souza criticized the International Olympic Committee (IOC), alleging institutional corruption and inadequate athlete compensation. He also advocated for the abolition of the World Anti-Doping Agency (WADA), characterizing it as an "anti-science" extension of the IOC. D'Souza also argued that the Olympic program includes insignificant sports. He states that he has never used performance-enhancing drugs himself. By late 2025, he had been replaced as chief executive by Maximilian Martin, investment banker and bitcoin miner. Olympians attached to the organisation as of 2023 include Brett Fraser, Roland Schoeman, and Christina Smith. In 2025, Brett Hawke was named head swim coach. Other people include geneticist George Church. German biotech billionaire Christian Angermayer is co-founder of the organisation. D'Souza became Thiel's confidant in the process of leading the Gawker plan for him, and through Thiel's introduction, a friend of Angermayer. According to The Spectator, in December 2022, as D'Souza and other members of their small community of gay tech founders were about to gather for the annual party at Thiel's residence in Miami (formerly held while travelling the world, until Thiel had children), D'Souza came up with the idea of the Enhanced Games. After receiving positive feedback from Thiel (while other investors thought that the idea was "outside the Overton window"), D'Souza spent the next six months developing the project. Later, after reading about the plan on German media, Angermayer notified D'Souza that he wanted to come on board as a co-founder.

== Treatment == Available treatment falls into two modalities: treating infections and boosting the immune system. Prevention of Pneumocystis pneumonia with trimethoprim/sulfamethoxazole is useful in those who are immunocompromised. In the early 1950s, immunoglobulin (Ig) was used by doctors to treat patients with primary immunodeficiency through intramuscular injection. Ig replacement therapy infusions can be either subcutaneous or intravenously administered, resulting in higher Ig levels for about three to four weeks, although this varies with each patient.

Theanine , also known as L-γ-glutamylethylamide, N5-ethyl-L-glutamine, or γ-glutamylethylamide, is a bioactive, non-proteinogenic amino acid similar to the proteinogenic amino acids glutamic acid and L-glutamine. It is produced by certain plants such as the tea plant (Camellia sinensis), and by some fungi. Theanine was discovered in 1949 as a constituent of green tea and was isolated in 1950 from gyokuro tea leaves. Theanine constitutes about 1–2% of the dry weight of green tea leaves. Theanine is sold as a dietary supplement. It is packaged in gelatin capsules, tablets, and as a powder, and may be an ingredient in branded supplements with caffeine. It is also used as an ingredient in food and beverages. Japan approved its unlimited use in all foods (including chocolates, soft drinks, and herb teas) except infant food in 1964, and the US Food and Drug Administration has considered it safe at doses up to 250 milligrams (mg) per serving since 2007. In 2011, the European Food Safety Authority found there was insufficient evidence for a causal relationship between theanine consumption and improved cognitive function, alleviation of psychological stress, maintenance of normal sleep, or reduction of menstrual discomfort. A 2025 review found that theanine has been poorly studied to date, having inconsistent research quality and unreliable clinical trials.
Tetrodotoxin (TTX) is a potent neurotoxin. Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin. Although tetrodotoxin was discovered in these fish, it is found in several other animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails). It is also produced by certain infectious or symbiotic bacteria like Pseudoalteromonas, Pseudomonas, and Vibrio as well as other species found in symbiotic relationships with animals and plants. Although it produces thousands of intoxications annually and several deaths, it has shown efficacy for the treatment of cancer-related pain in phase II and III clinical trials. Tetrodotoxin is a sodium channel blocker. It inhibits the firing of action potentials in neurons by binding to the voltage-gated sodium channels in nerve cell membranes and blocking the passage of sodium ions (responsible for the rising phase of an action potential) into the neuron. This prevents the nervous system from carrying messages and thus muscles from contracting in response to nervous stimulation. Its mechanism of action – selective blocking of the sodium channel – was shown definitively in 1964 by Toshio Narahashi and John W. Moore at Duke University, using the sucrose gap voltage clamp technique.
=== 11 August === At least 40 people were killed in an RSF attack on Abu Shouk camp. The SAF claimed to have killed more than 200 RSF fighters and destroyed or captured 46 combat vehicles following an RSF attack on El Fasher. Nine people were abducted by the RSF during the event.
== Effectiveness == Negative pressure wound therapy is usually used with chronic wounds or wounds that are expected to present difficulties while healing (such as those associated with diabetes). Negative pressure wound therapy is approved by the FDA and numerous randomized controlled trials have been conducted on this technique, however, the evidence supporting how effective NPWT is compared to standard wound care dressings is not clear. Low-level evidence indicates that there may be a lower risk of death and less surgical site infections associated with NPWT compared to standard dressing care, however there may not be a difference in the risk of wound reopening when comparing the two approaches. NPWT may increase the risk of skin blistering compared to standard wound care. NPWT may be a more cost effective approach for closing wounds following a caesarean section in women who are obese, however, NPWT is not likely as cost effective for closing wounds associated with fracture surgeries. It is not clear if NPWT is cost effective for closing wounds associated with other types of surgery. NPWT has been used to treat non-trauma patients after abdominal surgery. Non-trauma patients are people who might need surgery for conditions such as abdominal infections or cancer. However, it is still not clear how safe and effective NPWT is for treating non-trauma patients with open abdomens. For treating diabetic ulcers of the feet, "consistent evidence of the benefit of NPWT" in the treatment of diabetic ulcers of the feet has been reported.
In 2011, food accounted for 70% of Indian retail, but was under-represented by organised retail. A.T. Kearney estimates India's organised retail had a 31% share in clothing and apparel, while the home supplies retail was growing between 20% and 30% per year. These data correspond to retail prospects prior to November announcement of the retail reform. It might be true that India has the largest number of shops per inhabitant. However, detailed figures are available for Belgium, the Netherlands, and Luxembourg. In Belgium, the number of outlets is approximately 8 per 1,000 inhabitants, while in the Netherlands it is 6 per 1,000 inhabitants. Therefore, the Indian figure must be significantly higher.

=== Salt coagulants === Calcium sulfate (gypsum) (Chinese: 石膏; pinyin: shígāo) is the traditional and most widely used coagulant to produce Chinese-style tofu, it produces a tofu that is tender but slightly brittle in texture. The coagulant itself has very little noticeable taste. Also known as gypsum, calcium sulfate is quarried from geological deposits, and no chemical processing or refining is needed, making it the cheapest coagulant used in tofu production. When used in production, the coagulation reaction is slower due to its low solubility, forming a smooth, more gelatinous tofu with relatively high water content and soft texture. Chloride-type nigari salts or lushui (simplified Chinese: 卤水; traditional Chinese: 鹵水; pinyin: lǔshuǐ) may also be used. Magnesium chloride and calcium chloride are highly soluble in water and affect soy protein in the same way, whereas gypsum is only very slightly soluble in water and acts differently in soy protein precipitation, the basis of tofu formation. These are the coagulants used to make tofu with a smooth and tender texture. In Japan, a white powder called nigari, which consists primarily of magnesium chloride, is produced from seawater after the sodium chloride is removed and the water evaporated. Depending on its production method, nigari/lushui may also contain small quantities of magnesium sulfate (Epsom salt), potassium chloride, calcium chloride, and trace amounts of other naturally occurring salts.
By the late 19th century, semisynthetic vanillin derived from the eugenol found in clove oil was commercially available. Synthetic vanillin became significantly more available in the 1930s, when production from clove oil was supplanted by production from the lignin-containing waste produced by sulfite pulping for preparing wood pulp for the paper industry. By 1981, a single pulp and paper mill in Thorold, Ontario, supplied 60% of the world market for synthetic vanillin. However, subsequent developments in the wood pulp industry have made its lignin wastes less attractive as a raw material for vanillin synthesis. Today, approximately 15% of the world's production of vanillin is still made from lignin wastes, while approximately 85% is synthesized in a two-step process from the petrochemical precursors guaiacol and glyoxylic acid. Beginning in 2000, Rhodia began marketing biosynthetic vanillin prepared by the action of microorganisms on ferulic acid extracted from rice bran. This product, sold at USD$700/kg under the trademarked name Rhovanil Natural, is not cost-competitive with petrochemical vanillin, which sells for around US$15/kg. However, unlike vanillin synthesized from lignin or guaiacol, it can be labeled as a natural flavoring.
To these words, La Feuille villageoise adds: "The example of honest, good farmers and landlords will suffice to familiarize the most stubborn day laborer with this new food; we could also use the ingenious means that were used in Ireland to accustom the least educated and least well-to-do portion of the people. In the schools, when a child had learned his lesson well, he was given a potato as a reward. When he had earned the prize for wisdom as well as for memory, he was given several; he ate them with delight; his classmates envied him, or feasted on the portion he was willing to give them. Sometimes he brought his apple home; the parents tasted it and found it good. Insensibly, the general repugnance of the people fell away, and it was not two generations before the potato became the favorite stew of the Irish."
=== Biosynthesis === Chloramphenicol is produced by Streptomyces venezuelae. Its biosynthesis has been partially elucidated. A portion of the structure originates from the shikimate pathway, in which aromatic amino acids are formed. The non-proteinogenic amino acid para-aminophenylalanine is also accessible via this pathway (step 1 in the scheme). This intermediate is bound to a peptidyl carrier protein via a thioester (2) and hydroxylated at the benzyl position (3). The amino group is then oxidized to the nitro group (4), the dichloroacetyl group is introduced from an unknown precursor (5), and the intermediate is released as an aldehyde (6). Reduction of the aldehyde group to the alcohol (7) yields chloramphenicol.
Most awards exclude managerial staff, and must exclude people based on the "seniority of their role" who were traditionally not covered, while "high income earners", paid over $167,500 in 2023, can agree to be exempt from an award if they have a guarantee of annual earnings. This means that, unless enterprise bargaining covers them, fair pay scales do not constrain rip-off executive pay that diminishes the pay of everyone else. Third, there are enterprise agreements, which are bargained between unions and employers to be higher, and under section 57 will displace any sector-wide award. However, in 2012, enterprise agreement coverage reached a peak of merely 27%, and by 2021 coverage fell to 15%, compared to coverages typically over 80% in European Union member states that promote sectoral collective bargaining.

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 is a laboratory-made peptide of forty-four amino acids whose sequence matches human growth hormone-releasing hormone, with a modified amino terminus. The modification is a short unsaturated fatty acid chain attached to the first residue. This change slows enzymatic breakdown and lengthens the time the peptide stays active in circulation.
