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.
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.
Once reconstituted, the peptide is handled as a solution and is less stable than the lyophilized powder. Aqueous solutions are commonly kept cold and used within a defined period. Buffer composition and pH influence degradation rates, with extremes of acidity or alkalinity accelerating hydrolysis. Preservatives may be added in multi-dose formats to limit microbial growth. Freezing and thawing of solutions is generally avoided because it can cause precipitation or loss of activity.
Identity and purity are assessed by reversed-phase high-performance liquid chromatography, which separates the peptide from related impurities. Mass spectrometry, often coupled to liquid chromatography, confirms molecular mass and detects chemical modifications. Peptide mapping and amino acid analysis can verify sequence integrity. Water content is measured by Karl Fischer titration, and residual solvents may be checked by gas chromatography. These methods together support batch-to-batch consistency and routine quality control.

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.
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.
Stability testing examines how the molecule changes under controlled stress. Thermal stress, light exposure, and extremes of pH are applied separately so that each degradation route can be attributed to a specific cause. The main observed changes are oxidation, deamidation, and aggregation into dimers or higher-order species. Accelerated studies at elevated temperature are used to estimate behavior over longer periods, though such extrapolation carries uncertainty. For a lyophilized powder, residual moisture and the choice of bulking agent strongly influence how quickly these changes appear.
Practical handling centers on limiting moisture, oxygen, and temperature excursions. Lyophilized material is generally held at or below minus twenty degrees Celsius, protected from light and kept sealed until use. Once reconstituted, solutions are typically kept cold and used within a short window because hydrolysis and microbial growth both accelerate in liquid form. Repeated freeze-thaw cycles are avoided, since they promote aggregation. Vial contents should be inspected for particulates and clarity before analysis, and working aliquots are prepared to reduce the number of times the stock is opened.
=== CT and MRI scans === Imaging of the pituitary gland is important in confirming hypersomatotropism in cats where it is suspected. Showing a pituitary mass is important to establish a final diagnosis alongside clinical findings and hormonal findings. Knowing the size of the pituitary mass is also necessary to decide the best course of treatment. In the vast majority of cats with hypersomatropism, it is caused by an adenoma of the somatotrophic cells. Said adenoma is typically visible by the time a cat presents with symptoms; however, if pituitary imaging is performed during the early stages of the disease, it may still be small and difficult to recognise. Rarely CT/MRI imaging may not reveal anything, this may either due to a small size of the tumour or due to a different aetiology for the acromegaly. Rarely in humans with acromegaly, somatotrophic hyperplasia as the result of growth hormone releasing hormones, caused by a tumour. This aetiology has not been observed in cats; however, a cat with normal CT and MRI imaging, the histopathology showed—instead of adenoma—acidophilic proliferation.
When supported by external democratic actors, coup leaders have an incentive to push for elections to retain external support and consolidate domestic legitimacy. When condemned, coup leaders are apt to trend toward authoritarianism to assure their survival. But coup conspirators also increasingly say that they chose a coup to save their country from the autocratic incumbents. Successful conspirators may hold free and fair elections simply because they think it is a good idea. A desire for economic growth and legitimacy have also been cited as motivations for democratization. Legal scholar Ilya Somin believes that a coup to forcibly overthrow a democratic government might sometimes be justified. Commenting on the 2016 Turkish coup d'état attempt, Somin opined,
WJ0679 is a small-molecule oxytocin receptor agonist and vasopressin receptor antagonist. It acts specifically as a very weak partial agonist of the oxytocin receptor (Ki = 422 nM; EC50Tooltip half-maximal effective concentration = 406 nM; EmaxTooltip maximal efficacy = 13%) and as an antagonist of the vasopressin V1A receptor (Ki = 105 nM; IC50Tooltip half-maximal inhibitory concentration = 2,203 nM), whereas no data were reported for the vasopressin V2 receptor. Despite its low activational efficacy at the oxytocin receptor, WJ0679 induces prosocial effects, including increased time spent in close physical contact and increased active social investigation, in rodents. The chemical synthesis of WJ0679 has been described. Along with its close analogue CA7, WJ0679 has the smallest chemical structure known for an oxytocin receptor agonist, with WJ0679 having about 60% of the molecular weight of LIT-001 and both WJ0679 and CA7 lacking LIT-001's tail component. Many analogues of WJ0679 and CA7 have been described. WJ0679 was first described in the scientific literature by a group including Michael Kassiou, Michael Bowen, Iain McGregor, and others at the University of Sydney in 2018. This group has founded a startup pharmaceutical company called Kinoxis Therapeutics and is developing small-molecule oxytocin-related drugs like KNX-100 and the KNX-200 series for potential medical use as of the 2020s.
== Chemistry == Radium only exhibits the oxidation state of +2 in solution. It forms the colorless Ra2+ cation in aqueous solution, which is highly basic and does not form complexes readily. Most radium compounds are therefore simple ionic compounds, though participation from the 6s and 6p electrons (in addition to the valence 7s electrons) is expected due to relativistic effects and would enhance the covalent character of radium compounds such as RaF2 and RaAt2. For this reason, the standard electrode potential for the half-reaction Ra2+ (aq) + 2e- → Ra (s) is −2.916 V, even slightly lower than the value −2.92 V for barium, whereas the values had previously smoothly increased down the group (Ca: −2.84 V; Sr: −2.89 V; Ba: −2.92 V). The values for barium and radium are almost exactly the same as those of the heavier alkali metals potassium, rubidium, and caesium.

The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, carboxy tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH). When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The convention for writing peptide sequences is to put the C-terminal end on the right and write the sequence from N- to C-terminus.
=== Political trends and results === Several politicians have spent part of their lives in the city: Jules Lecesne (1818–1878), Jules Siegfried (1837–1922), and Félix Faure (1841–1899) were elected as municipal councillors and MPs. A pool, a shopping centre and a street have been named after René Coty from Le Havre, who served as President of the French Republic from 1954 to 1959. Christine Lagarde (born 1956) attended high schools in Le Havre before becoming Minister of the Economy and Director-General of the International Monetary Fund in 2011. Since 23 October 2010 the mayor has been Édouard Philippe (UMP). He also holds the presidency of the CODAH and has held a seat in the National Assembly for the 7th district of Seine-Maritime since 2012. He succeeded Antoine Rufenacht (UMP), who was mayor of Le Havre for fifteen years before resigning, as the head of the municipality. The city of Le Havre has long been the strongest bastion of the Communist Party of France, who directed it from 1956 to 1995. Overall, the inhabitants of Le Havre in the 7th electoral district (city centre and western neighbourhoods) tend to vote for the right while those of the 8th electoral district (eastern neighbourhoods) tend to choose the candidate of the left. For example, in the presidential election of 2007, the 7th electoral district voted for Nicolas Sarkozy (UMP) by 55.05% against 44.95% for Ségolène Royal (PS) while in the 8th electoral district 55.02% voted for the Socialist candidate.
In an interview for Politico on 5 February, María Corina Machado indicated that elections could be held in Venezuela in 9 to 10 months, using manual voting. She said that she had not discussed about elections with Trump. National Assembly president and brother of Delcy, Jorge Rodríguez ruled out the possibility of elections in the near future in an interview for Newsmax. In an interview for NBC on 12 February, Delcy Rodríguez was asked if she will hold free and fair elections, she answered "absolutely" adding it will be decided as part of the "political dialogue." Also interviewed for the NBC, US Secretary of Energy Chris Wright, speaking from Caracas, said that elections could be held in the Venezuela before the end of second presidency of Donald Trump, and added about Machado that he "listened to her in a podcast a few days ago, she was asked that question: how fast can they hold elections in Venezuela? What do you think should happen, María? And she said to get it, probably the fastest it could be done it probably takes 9 to 10 months to get there. So I think she is realistic about what the changes that need to happen.
Nuevas Ideas retained its Legislative Assembly supermajority and, with its allies, won 43 of the country's 44 municipalities. Several news outlets described the election results as a "landslide victory" for Bukele and Nuevas Ideas, and Bukele described his victory as "the record in the entire democratic history of the world". The TSE granted Bukele his presidential credentials on 29 February and his second term began on 1 June. In a 2024 interview with Time, Bukele declined to run for a third term in the next presidential election. In July 2025, the Legislative Assembly passed several constitutional amendments, among them, the abolition of presidential term limits that made Bukele eligible to run for re-election indefinitely. Additionally, the legislature voted to move the date of the next presidential election from 2029 to 2027, reducing the length of Bukele's second term by two years. In December 2025, Bukele told YouTuber TheGrefg that "if it were up to me, I would stay for 10 more years". On 28 June 2026, Bukele registered as a pre-candidate with Nuevas Ideas, seeking a third presidential term; on 12 July, the party formally nominated him as its presidential candidate.
This PFS benefit was consistent across subgroups with individual high-risk cytogenetic abnormalities, including patients with del(17p). PFS was also longer with IRd versus placebo- in patients with 1q21 amplification, and in the "expanded high-risk" group, defined as those with high-risk cytogenetic abnormalities and/or 1q21 amplification. IRd demonstrated substantial benefit compared with placebo in relapsed/refractory multiple myeloma patients with high-risk and standard-risk cytogenetics, and improves the poor PFS associated with high-risk cytogenetic abnormalities.

Weighted Companion Cubes are variants of Weighted Storage Cubes that are used in the testing chambers. They are differentiated from regular Storage Cubes with small pink hearts on its external surface, instead of an Aperture Science logo. In Portal, during test chamber 17, Chell is given a Weighted Companion Cube by GLaDOS, told by her that it will be her faithful companion for the duration of the test. Chell must use the Cube to complete the chamber, at which point GLaDOS requires her to incinerate the Cube before being able to progress further. The requirement to incinerate the companion cube originates from test-play of Portal, during which players brought their companion cube with them to later levels, with unexpected impact on game play. Another Companion Cube is seen at the end of the game, standing next to the cake. In Portal 2, redesigned Weighted Companion Cubes appear in test chamber 7 in chapter 2. GLaDOS fizzles two of them at the start of the test to annoy Chell. Chell is given the option to take a Weighted Companion Cube with her at the end of the test, but if Chell does this, GLaDOS fizzles the Companion Cube before Chell can enter the lift leading to the next test chamber. A Companion Cube with the old design, supposedly the one from Portal, appears at the very end of the game, as it is ejected, charred and singed, from the shed (possibly at ground level) shortly after Chell's departure. Companion Cubes are also mentioned a lot in the Ratman dens in Portal. In the Lab Rat comic, Ratman is also accompanied by a Companion Cube, which he imagines talks to him.
== Renal Impairment == Dose adjustment is necessary based on the degree of renal function: Mild Renal Impairment (eGFR ≥ 60 mL/min/1.73 m²): No dose adjustment required. Moderate Renal Impairment (eGFR 30–59 mL/min/1.73 m²): Reduce dose to 50 mg once weekly. Severe Renal Impairment or ESRD (eGFR < 30 mL/min/1.73 m² or on dialysis): Reduce dose to 25 mg once weekly, with close monitoring.
In 1987, according to Department of State and congressional staff, drug traffickers were offering UMOPAR officers and town officials in the Chapare region amounts ranging from US$15,000 to US$25,000 for seventy two hours of "protection" in order to allow aircraft to load and take off from clandestine airstrips. In February 1988, the deputy minister of national defense announced that about 90 percent of UMOPAR members, including twelve middle- and high-ranking officers, had been dismissed for alleged links to drug trafficking. The La Paz newspaper Presencia reported in March 1988 that UMOPAR chiefs, including the prosecutors, were working with narcotics traffickers by returning to them the large drug finds and turning only the small ones in to the authorities. Observers considered UMOPAR forces in Santa Cruz to be more honest and dedicated. In October 1988, the undersecretary of the Social Defense Secretariat reiterated that drug traffickers had obtained the protection of important sectors of influence in Bolivia, including some military members and ordinary judges. He cited the example of Cochabamba's Seventh Division commander and four of his top officers, who were discharged dishonorably after they were found to be protecting a clandestine Chapare airstrip used by drug smugglers. The ministry official also announced that the navy was protecting drug-trafficking activities in the Puerto Villarroel area of the Chapare. For that reason, the United States suspended assistance to the navy temporarily in late 1988 until its commander was replaced.
====== Master's degree and Graduate Certificate Programs in Pharmacy Leadership ====== In 2016, the college became the first pharmacy school in the US to offer an online MS degree program and graduate certificate in pharmacy leadership. These programs combine leadership and professional development in health care business and management courses. These are the first programs at the university to be a partnership between three difference colleges:

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.
The clinical program was designed around HIV-associated lipodystrophy, a condition in which fat accumulates abnormally around the internal organs. Trials enrolled that specific population, so the evidence base covers it rather than the general population. Regulators approved the drug for the studied indication only, and promotion outside it is not permitted.
Growth hormone therapy supplies the finished hormone directly, while this peptide acts upstream and asks the pituitary to secrete its own. That difference means the response depends on a functioning pituitary and on the body's normal feedback loops. It also means the circulating hormone profile is pulsatile rather than a flat, injected level.
Refrigeration between 2 and 8 degrees Celsius is typical, with protection from moisture and light. Dry, sealed containers help maintain stability over the labeled shelf life. Temperature cycling is usually minimized.
