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.
Receptor-level activity begins when the peptide binds the GHRH receptor, a class B G-protein-coupled receptor found on pituitary somatotroph cells. Occupancy triggers Gs-mediated activation of adenylyl cyclase and a rise in intracellular cyclic AMP, which in turn promotes synthesis and pulsatile release of growth hormone. Because the compound acts upstream of the growth hormone axis rather than supplying hormone directly, its effect depends on intact pituitary function. Binding studies in cell culture and animal models have established this pathway; the detailed kinetics of receptor recycling in humans remain less well characterized.
Physicochemical behavior is dominated by the peptide backbone. The molecule is hydrophilic and carries a net positive charge near neutral pH, owing to several arginine and lysine residues. In solution it adopts a largely unstructured conformation, and aggregation is a known concern for peptide products of this size. Oxidation of methionine and deamidation of asparagine or glutamine residues are the principal chemical degradation routes. These liabilities shape how the material is formulated, handled, and analyzed, and they explain why lyophilized presentations are common in research settings.
Tesamorelin is a synthetic peptide analog of growth hormone-releasing hormone, built from 44 amino acids. Its sequence follows the natural human GHRH(1-44) backbone, with a trans-3-hexenoyl group attached to the N-terminal tyrosine. This modification blocks recognition by dipeptidyl peptidase IV, the enzyme that rapidly truncates the native hormone in circulation. The result is a molecule with a substantially longer plasma residence time than unmodified GHRH, which makes it practical for clinical and laboratory study.

研究背景集中在特定人群的体成分改变，尤其是与脂肪分布异常相关的内脏脂肪堆积。不同地区对它的监管状态与获批适应症并不一致，部分市场仅限特定诊断人群使用。在一般人群中的长期效应、与其他激素的相互作用以及停药后的维持情况仍属开放问题，现有数据不足以给出普遍结论。
tesamorelin 是一种人工合成的四十四肽，序列与内源性生长激素释放激素（GHRH）的 1-44 片段一致，区别在于 N 端加接了一个反式-3-己烯酰基。该修饰抑制二肽基肽酶 IV 的快速切割，从而延长分子在循环中的存留时间。作为肽类分子，它难以经胃肠道吸收，文献中讨论的均是注射途径。分类上通常把它归为 GHRH 类似物，以区别于生长激素本身。
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.
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.

== History == Plans for a successor to the original Source engine began following the release of Half-Life 2: Episode Two in 2007. The first engine tech demo was created in 2010 by remaking a map from Left 4 Dead 2. Images of this were leaked onto the internet in early 2014. At the 2014 Game Developers Conference, Valve employee Sergiy Migdalskiy showed off a Source 2 physics debugging tool being used in Left 4 Dead 2. Source 2 was first made available via Steam Workshop tools for Dota 2 in 2014 prior to it being officially announced at the 2015 Game Developers Conference. There, Valve stated their intent for it was to allow for content to be created more efficiently. Valve also stated that it would support the Vulkan graphics API and use a new in-house physics engine called Rubikon, which would replace the need for the third-party Havok tools. Gabe Newell, president and founder of Valve, said that the company were prioritizing the development of their own games before they would release the engine and its software development kit to the public. This was to ensure the highest quality for developers; he added that they were intending to make the engine free to use for game developers as long as the game is published on their Steam service. In June 2015, Valve announced that the entirety of Dota 2 would be ported over to Source 2 in an update called Dota 2 Reborn. Reborn was first released to the public as an opt-in beta update that same month before officially replacing the original client in September 2015, making it the first game to use the engine.
=== Cancer risk === Studies are mixed on whether the risk of breast cancer is increased with hormone therapy in transgender women. Two cohort studies found no increase in risk relative to cisgender men, whereas another cohort study found an almost 50-fold increase in risk such that the incidence of breast cancer was between that of cisgender men and cisgender women. There is no evidence that breast cancer risk in transgender women is greater than in cisgender women. Twenty cases of breast cancer in transgender women have been reported as of 2019. Cisgender men with gynecomastia have not been found to have an increased risk of breast cancer. It has been suggested that a 46,XY karyotype (one X chromosome and one Y chromosome) may be protective against breast cancer compared to having a 46,XX karyotype (two X chromosomes). Men with Klinefelter's syndrome (47,XXY karyotype), which causes hypoandrogenism, hyperestrogenism, and a very high incidence of gynecomastia (80%), have a dramatically (20- to 58-fold) increased risk of breast cancer compared to karyotypical men (46,XY), closer to the rate of karyotypical women (46,XX). The incidences of breast cancer in karyotypical men, men with Klinefelter's syndrome, and karyotypical women are approximately 0.1%, 3%, and 12.5%, respectively. Women with complete androgen insensitivity syndrome (46,XY karyotype) never develop male sex characteristics and have normal and complete female morphology, including breast development, yet have not been reported to develop breast cancer.
=== Cricket === Bromley Cricket Club was founded in 1820, but evidence of cricket being played in Bromley dates to 1735. Bromley CC has a significant success record, with 9 Kent Cricket League championship titles to their name. Bromley field four senior teams. Three compete in the Kent Cricket League (a designated ECB Premier League) and one plays in the British Tamil Cricket League. They also have an established junior training section that play competitive cricket in the North Kent Junior League.

At the end of his schooldays, Adorno not only benefited from the rich concert offerings of Frankfurt—where one could hear performances of works by Schoenberg, Schreker, Stravinsky, Bartók, Busoni, Delius, and Hindemith—but also began studying music composition at the Hoch Conservatory while taking private lessons with well-respected composers Bernhard Sekles and Eduard Jung. At around the same time, he befriended Siegfried Kracauer, the Frankfurter Zeitung's literary editor, of whom he would later write:
Sonopuncture is a stimulation of the body similar to acupuncture using sound instead of needles. This may be done using purpose-built transducers to direct a narrow ultrasound beam to a depth of 6–8 centimetres at acupuncture meridian points on the body. Alternatively, tuning forks or other sound emitting devices are used. Acupuncture point injection is the injection of various substances (such as drugs, vitamins or herbal extracts) into acupoints. This technique combines traditional acupuncture with injection of what is often an effective dose of an approved pharmaceutical drug, and proponents claim that it may be more effective than either treatment alone, especially for the treatment of some kinds of chronic pain. However, a 2016 review found that most published trials of the technique were of poor value due to methodology issues and larger trials would be needed to draw useful conclusions. Auriculotherapy, commonly known as ear acupuncture, auricular acupuncture, or auriculoacupuncture, is considered to date back to ancient China. It involves inserting needles to stimulate points on the outer ear. The modern approach was developed in France during the early 1950s. There is no scientific evidence that it can cure disease; the evidence of effectiveness is negligible. Scalp acupuncture, developed in Japan, is based on reflexological considerations regarding the scalp. Koryo hand acupuncture, developed in Korea, centers around assumed reflex zones of the hand.
== Etymology == The English word frankincense derives from the Old French expression franc encens, meaning 'true incense', maybe with the sense of 'high quality incense'. The adjective franc in Old French meant 'noble, true', in this case perhaps 'pure'; although franc is ultimately derived from the tribal name of the Franks, it is not a direct reference to them in the word frankincense. The word for frankincense in the Koine Greek of the New Testament, λίβανος, líbanos (or λιβανωτός, libanōtós), is cognate with the name of Lebanon (Greek: Λίβανος); the same can be said with regard to Arabic, Phoenician, Hebrew, and Vulgar Latin: lĭbănus. This is postulated to be because they both derive from the word for 'white' and that the spice route went via Mount Lebanon (Koine Greek: Λίβανος, romanized: Libanos). Medieval Latin: olibanum derived from λίβανος or libanus. The leading "o" may have come from Latin: oleum, lit. 'oil', or from the Greek article o- or Arabic article al-. Other names include Arabic: اللبان, romanized: al-lubān, Persian: کندر, romanized: kondor, Syriac: בוּסמִין, romanized: busmin, Hebrew: לבונה, romanized: ləvonā, Bengali: লোবান, ধুনো, romanized: lōban, dhunō, Somali: foox (fooḥ), Turkish: akgünlük, Classical Latin: tūs.
Shimeji (Japanese: シメジ, 占地 or 湿地) is a group of edible mushrooms native to East Asia, but also found in northern Europe. Hon-shimeji (Lyophyllum shimeji) is a mycorrhizal fungus and difficult to cultivate. Other species are saprotrophs, and buna-shimeji (Hypsizygus tessulatus) is now widely cultivated. Shimeji is rich in umami-tasting compounds such as guanylic acid, glutamic acid, and aspartic acid.
Cardiac markers are biomarkers measured to evaluate heart function. They can be useful in the early prediction or diagnosis of disease. Although they are often discussed in the context of myocardial infarction, other conditions can lead to an elevation in cardiac marker level. Cardiac markers are used for the diagnosis and risk stratification of patients with chest pain and suspected acute coronary syndrome and for management and prognosis in patients with diseases like acute heart failure. Most of the early markers identified were enzymes, and as a result, the term "cardiac enzymes" is sometimes used. However, not all of the markers currently used are enzymes. For example, in formal usage, troponin would not be listed as a cardiac enzyme.

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.
The principal difference is a chemical cap on the N-terminal tyrosine that prevents rapid enzymatic cleavage. Native GHRH is degraded within minutes in plasma, whereas the modified peptide persists considerably longer. The amino acid backbone otherwise mirrors the natural hormone.
