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.
Tesamorelin binds to growth hormone-releasing hormone receptors on the surface of pituitary somatotroph cells. This binding activates adenylate cyclase, raising intracellular cyclic AMP levels and triggering the release of growth hormone into circulation. The elevated growth hormone then stimulates hepatic production of insulin-like growth factor 1. Because the effect is mediated through the endogenous axis, secretion remains subject to feedback regulation. This distinguishes it from direct growth hormone administration, which bypasses pituitary control entirely.
Clinical investigation has focused on HIV-associated lipodystrophy, a condition in which antiretroviral therapy contributes to abnormal fat distribution. Excess visceral adipose tissue accumulates in the abdomen while peripheral fat may be lost. Tesamorelin was evaluated for reducing this visceral fat depot, with trials measuring changes in abdominal fat by imaging rather than by body weight alone. The rationale rests on the known lipolytic effects of growth hormone. Effects on visceral fat are documented, while long-term outcomes regarding cardiovascular risk remain less clearly established.

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.
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.
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.
在临床研究之外，特沙莫瑞林常被讨论为生长激素分泌促进剂，但这一说法需要限定。它并不等同于生长激素本身，也不属于普通减重药物。部分研究关注其减少腹部脂肪和改善脂质谱的潜力，另一些研究则关注胰岛素抵抗和 IGF-1 升高等信号。这些效应的临床意义仍在评估中，尚未形成统一结论。

== Causes == OMA is a neurological condition. Although some brain imaging studies of people with OMA reveal a normal brain, some MRI studies have revealed unusual appearance of some brain areas, in particular the corpus callosum, cerebellum, and fourth ventricle. Oculomotor apraxia can be acquired or congenital. Sometimes no cause is found, in which case it is described as idiopathic. A person may be born with the parts of the brain for eye movement control not working, or may manifest poor eye movement control in childhood. If any part of the brain that controls eye movement becomes damaged, then OMA may develop. One of the potential causes is bifrontal hemorrhages. In this case, OMA is associated with bilateral lesions of the frontal eye fields (FEF), located in the caudal middle frontal gyrus. The FEF control voluntary eye movements, including saccades, smooth pursuit and vergence. OMA can also be associated with bilateral hemorrhages in the parietal eye fields (PEF). The PEF surround the posterior, medial segment of the intraparietal sulcus. They have a role in reflexive saccades, and send information to the FEF. Since the FEF and PEF have complementary roles in voluntary and reflexive production of saccades, respectively, and they get inputs from different areas of the brain, only bilateral lesions to both the FEF and PEF will cause persistent OMA. Patients with either bilateral FEF or bilateral PEF damage (but not both FEF and PEF) have been shown to regain at least some voluntary saccadic initiation some time after their hemorrhages.
=== Abuse potential === Remifentanil, being a μ-receptor agonist, functions like other μ-receptor agonists, such as morphine and codeine; it can cause euphoria and has the potential for abuse. However, due to its rapid metabolism and short-acting half-life the likelihood of abuse is quite low. Nevertheless, there have been some documentations of remifentanil abuse.
Its use is generally restricted to severe infections largely in hospitalized patients. The recommended dosage is 250 mg to 1 gram given intravenously every 6 to 8 hours or in intramuscular doses of no more than 1.5 gm daily, usually for five to 14 days. It is commercially available as Primaxin as 250-mg or 500-mg infusion bottles for IV use or 500-mg or 750-mg vials of lyophilized powder for IM injection. The most common side effects of imipenem are diarrhea, nausea, vomiting, skin rash, pruritus, and injection-site reactions.
=== Social policies: "Three Transformations" === Perhaps inspired by the Three Principles of the People, Liu Wenhui adopted a frontier policy known as the "Three Transformations" (san hua zhengce, 三化政策). Although described by Liu as a policy, it was closer to a loose model of governance. These three transformations included transformation through virtuous rule (de hua; 德化), transformation through assimilation (tong hua; 同化), and transformation through progress (jin hua; 進化). For Liu, virtuous rule was to win the hearts and minds of the non-Han populace, and progress would establish an interventionist, "fluid" government that avoided "static" stagnation under laissez-faire rule. However, Liu refrained from elucidating on the exact nature such progress would take. Liu also reportedly adopted different management styles for areas of Xikang depending on the ethnic group that inhabited them. For Tibetan areas, he advocated "steady progress" (稳进); for Han areas, "gradual progress" (逐进). Finally, for Yi areas, he called for "rapid progress" (猛进). These were called the "Three Advances" (三进主义). On the matter of ethnic policy, Liu's government was highly selective. Although his administration was relatively tolerant of Tibetans, even patronizing Tibetan Buddhism and establishing schools for Tibetan students, it was highly discriminatory against the Yi people, calling for the complete erasure of Yi identity. For many Han settlers in Xikang, the Yi were a "scourge", associated with violence and slave-raiding; the Yi, in turn, spoke of a "Han scourge".

In 2023, LECO and Cal State LA worked in tandem to launch a new chemical analysis lab. The new lab would work with both undergraduate and graduate students within the Department of Chemistry and Biochemistry. Since 2025, the cement industry has been working to reduce carbon emissions and adopt more sustainable production methods. The LECO Corporation provides analytical instrumentation to support that transition. Its portfolio has included calorimeters, thermogravimetric analyzers, and combustion analyzers that measure factors such as calorific value, moisture, ash, carbon, sulfur, and loss on ignition in fuels and raw materials. This helps cement producers evaluate alternative inputs, monitor performance, and improve operational efficiency while reducing environmental impact. Research was also conducted at Oxford by scholars within the Department of Materials which tested the LECO process of testing solar cells and silicon materials.
On January 18, 2015, Alice in Chains performed in the halftime show of the NFC Championship Game between the Seattle Seahawks and the Green Bay Packers at CenturyLink Field in Seattle. Cantrell is a lifelong Seahawks fan and often attends their games. In August 2015, Bassist Mike Inez said that the band had been "throwing around riffs for a new record" and "taking it nice and slow". The band toured in the summer of 2015 and the summer of 2016, including select shows opening for Guns N' Roses as part of the Not in This Lifetime... Tour. The band finished their 2016 tour with a concert at the Grand Sierra Resort and Casino in Reno, Nevada on October 8, 2016. In November 2016, Alice in Chains released a cover of the Rush song "Tears", which was included in the 40th anniversary release of the album 2112. The home video Live Facelift was released on vinyl for the first time on November 25, 2016, as part of Record Store Day's Black Friday event. The album features six songs and only 5000 copies were issued. To celebrate the tenth anniversary of Record Store Day, on April 22, 2017, Legacy Recordings released "Get Born Again"/"What the Hell Have I", a special 45 RPM double 7" single featuring four tracks remastered and available on vinyl for the first time, "What the Hell Have I", "A Little Bitter", "Get Born Again" and "Died".

=== Medications === Oral medications like Glipizide that stimulate the pancreas, promoting insulin release (or in some cases, reduce glucose production), are less and less used in cats, and these drugs may be completely ineffective if the pancreas is not working. These drugs have also been shown in some studies to damage the pancreas further or to cause liver damage. Some owners are reluctant to switch from pills to insulin injections, but the fear is unjustified; the difference in cost and convenience is minor (most cats are easier to inject than to pill), and injections are more effective at treating the disease. Bexagliflozin (Bexacat) was approved for medical use in the United States in December 2022. It is the first sodium-glucose cotransporter 2 (SGLT2) inhibitor new animal drug approved by the US Food and Drug Administration (FDA) in any animal species. Velagliflozin (Senvelgo), another SGLT2 inhibitor, was approved for medical use in the United States in August 2023 by the FDA. SGLT2 inhibitors are not insulin, nor do they help a diabetic cat's cells use glucose for energy. SGLT2 inhibitors lowers blood glucose levels by excreting glucose through the kidneys. Both medications are prescription only and are given orally (by mouth) once daily. Cats that have been previously treated with long-term insulin therapy, are currently on long-term insulin therapy, or has other underlying health conditions should not take these medications.

Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes. Ribosomal RNA is transcribed from ribosomal DNA (rDNA) and then bound to ribosomal proteins to form small and large ribosome subunits. rRNA is the physical and mechanical factor of the ribosome that forces transfer RNA (tRNA) and messenger RNA (mRNA) to process and translate the latter into proteins. Ribosomal RNA is the predominant form of RNA found in most cells; it makes up about 80% of cellular RNA despite never being translated into proteins itself. Ribosomes are composed of approximately 60% rRNA and 40% ribosomal proteins, though this ratio differs between prokaryotes and eukaryotes.

The smoke point, also referred to as the burning point, is the temperature at which an oil or fat begins to produce a continuous bluish smoke that becomes clearly visible, dependent upon specific and defined conditions. This happens when one or multiple substances in the oil start to chemically react with oxygen and burn, which can include the oil itself, proteins, sugars, or other organic material. It is distinct from the flash point and fire point, which denote the temperatures at which the oil itself (specifically, vaporized oil, which is distinct from the smoke produced at the smoke point) begins to burn. Smoke point values can vary greatly. The most important factor determining the smoke point of an oil is the amount of proteins and free fatty acids (FFAs). Higher quantities of these lower the smoke point. The FFA content typically represents less than 1% of the total oil and consequently renders smoke point a poor indicator of the capacity of a fat or oil to withstand heat, in a non-cuisine related sense. Virgin (raw) oils, which contain various flavorful organic compounds, have lower smoke points than refined oils because the organic compounds burn. Animal-based fats and oils tend to have lower smoke points than vegetable-based ones, as well. Oils made of polyunsaturated fats have lower smoke points, those made of monounsaturated fats have middling smoke points, and oils made of saturated fats have even higher smoke points. The level of refinement, seed variety, and climate and weather of growth of the source plants also significantly affect its smoke point.
In epigenetics, proline isomerization is the effect that cis-trans isomerization of the amino acid proline has on the regulation of gene expression. Similar to aspartic acid, the amino acid proline has the rare property of being able to occupy both cis and trans isomers of its prolyl peptide bonds with ease. Peptidyl-prolyl isomerase, or PPIase, is an enzyme very commonly associated with proline isomerization due to their ability to catalyze the isomerization of prolines. PPIases are present in three types: cyclophilins, FK506-binding proteins, and the parvulins. PPIase enzymes catalyze the transition of proline between cis and trans isomers and are essential to the numerous biological functions controlled and affected by prolyl isomerization (i.e. cell signalling, protein folding, and epigenetic modifications) Without PPIases, prolyl peptide bonds will slowly switch between cis and trans isomers, a process that can lock proteins in a nonnative structure that can affect render the protein temporarily ineffective. Although this switch can occur on its own, PPIases are responsible for most isomerization of prolyl peptide bonds. The specific amino acid that precedes the prolyl peptide bond also can have an effect on which conformation the bond assumes. For instance, when an aromatic amino acid is bonded to a proline the bond is more favorable to the cis conformation. Cyclophilin A uses an "electrostatic handle" to pull proline into cis and trans formations.

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 synthetic analog of growth hormone-releasing hormone, a hypothalamic peptide. It functions as a growth hormone secretagogue acting at pituitary receptors. The classification separates it from direct growth hormone products.
