Everything below concerns GHRH receptor. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-11-08. Where a claim depends on a specific study, the study is described rather than over-claimed.
Measured responses usually involve growth hormone and insulin-like growth factor 1, known as IGF-1. Growth hormone rises in bursts and is difficult to sample reliably, while IGF-1 shifts more slowly and can be assessed from a single blood draw. Studies therefore treat IGF-1 as the more practical pharmacodynamic marker. Both are indirect, showing that the receptor was engaged rather than that the peptide reached a particular concentration. Direct exposure measurement requires an assay aimed at the molecule itself.
Published work tends to frame tesamorelin as a tool for studying the GHRH axis and as a compound with measurable effects on body composition. Reports often describe visceral adipose tissue as an endpoint, assessed by imaging rather than by inference. Analytical sections commonly describe liquid chromatography with tandem mass spectrometry to confirm identity and purity, because immunoassays may cross-react with related fragments. Where results diverge between studies, differences in assay choice, sampling timing, and population are frequent explanations offered. Whether effects persist after treatment stops remains an open question.
Whether the drug improves hard clinical outcomes is not settled. No completed trial has shown a reduction in heart attacks or strokes among treated patients, although a dedicated cardiovascular outcomes study has been discussed in the literature. Investigators have also examined hepatic fat in people with HIV and fatty liver disease, cognitive measures in small cohorts, and changes in bone density. Regulatory labeling emphasizes monitoring of insulin-like growth factor 1 because supraphysiologic levels raise questions about tissue growth, and the clinical significance of that signal remains an open question rather than a demonstrated harm.
Binding of tesamorelin to the growth hormone-releasing hormone receptor on anterior pituitary somatotrophs activates a Gs protein pathway, raises cyclic AMP, and triggers release of stored growth hormone into the bloodstream. Because the analogue resists dipeptidyl peptidase-4, its plasma residence time exceeds that of native GHRH, producing a larger and more sustained secretory signal. The released growth hormone then acts on the liver and peripheral tissues to raise insulin-like growth factor 1, which feeds back on the hypothalamus and pituitary. This axis explains both the intended effects on fat distribution and the biological markers used to track them.

== Disease cycle == P. expansum infects a fruit via wounds through which the conidia are able to enter. Usually, puncturing, bruising, and limb rubs occur during harvesting, packaging, and processing of the fruit, all of which provide sites through which spores can enter the fruit. Conidia can be found in soil, decaying debris, and tree bark, and can survive cold temperatures. Conidia may be isolated from the air of the orchard and packaging house, on the walls of the packaging houses, and from the water and fungicide solution into which harvested fruits are dunked before packaging or storage. Exposure to conidia at any step of growth, harvesting, processing, shipping, and storage can lead to inoculation and disease. Conidia that have gained access via a wound can germinate to form a germ tube. This germ tube will continue to grow as hyphae, which colonize the fruit, killing fruit cells in an expanding infection. If the fungus has colonized the fruit with mycelium, the formation of conidiophores occurs on the surface or subsurface of the hyphae. The conidiophores are mostly smooth-walled terverticillate penicilli. A terverticillate pencilii has multiple branch points below the phialides, the cells that the conidia are attached to. However, at times, the penicilli may be rough or biverticillate (only two levels of branching). The phialides are packed close together with nearly a cylindrical shape. The conidia are dry, smooth, elliptical, and "dull-green" in color and are often disseminated by wind currents. Sexual reproduction has not been observed in nature for P. expansum.
DNA repair The set of processes by which a cell identifies and corrects structural damage or mutations in the DNA molecules that encode its genome. The ability of a cell to repair its DNA is vital to the integrity of the genome and the normal functionality of the organism.
Na = nitrogen absorbed in proteins on the test diet Nr = nitrogen incorporated into the body on the test diet However direct measurement of Nr is essentially impossible. It will typically be measured indirectly from nitrogen excretion in urine. Faecal excretion of nitrogen must also be taken into account - this part of the ingested protein is not absorbed by the body and so not included in the calculation of BV. An estimate is used of the amount of the urinary and faecal nitrogen excretion not coming from ingested nitrogen. This may be done by substituting a protein-free diet and observing nitrogen excretion in urine or faeces, but the accuracy of this method of estimation of the amount of nitrogen excretion not coming from ingested nitrogen on a protein-containing diet has been questioned.
In statistics, describes a mathematical measure of difference between groups. The difference is said to be significant if it is greater than what might be expected to happen by chance alone. Also called statistically significant. (NCI) Single blind study
Soybean seed contains 18–19% oil. To extract soybean oil from seed, the soybeans are cracked, adjusted for moisture content, rolled into flakes, and solvent-extracted with commercial hexane. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially hydrogenated, are exported abroad, sold as "vegetable oil", or end up in a wide variety of processed foods. As of 2022, China produces 29% of the world's soybean oil and the United States is the second largest producer at 21%.

ångström (Å) A non-SI, metric unit of length equal to 10−10 metre, i.e. 1⁄10000000000 of a metre or 0.1 nanometre. The angstrom is commonly used in the natural sciences to express microscopic or atomic-scale distances, including the sizes of atomic nuclei, wavelengths of electromagnetic radiation, and lengths of chemical bonds (e.g. the covalent radius of a chlorine atom averages about 1 angstrom).

The interpretation of the law of definite proportions in terms of the atomic theory of matter implied that the masses of atoms of various elements had definite ratios that depended on the elements. While the actual masses were unknown, the relative masses could be deduced from that law. In 1803 John Dalton proposed to use the (still unknown) atomic mass of the lightest atom, hydrogen, as the natural unit of atomic mass. This was the basis of the atomic weight scale. For technical reasons, in 1898, chemist Wilhelm Ostwald and others proposed to redefine the unit of atomic mass as 1/16 the mass of an oxygen atom. That proposal was formally adopted by the International Committee on Atomic Weights (ICAW) in 1903. That was approximately the mass of one hydrogen atom, but oxygen was more amenable to experimental determination. This suggestion was made before the discovery of isotopes in 1912. Physicist Jean Perrin had adopted the same definition in 1909 during his experiments to determine the atomic masses and the Avogadro constant. This definition remained unchanged until 1961. Perrin also defined the "mole" as an amount of a compound that contained as many molecules as 32 grams of oxygen (O2). He called that number the Avogadro number in honor of physicist Amedeo Avogadro.
In 1968, a period of political liberalization took place in Czechoslovakia called the Prague Spring. An "Action Program" of reforms included increasing freedom of the press, freedom of speech and freedom of movement, along with an economic emphasis on consumer goods, the possibility of a multiparty government, limitations on the power of the secret police, and potential withdrawal from the Warsaw Pact. In answer to the Prague Spring, on 20 August 1968, the Soviet Army, together with most of their Warsaw Pact allies, invaded Czechoslovakia. The invasion was followed by a wave of emigration, including an estimated 70,000 Czechs and Slovaks initially fleeing, with the total eventually reaching 300,000. The invasion sparked intense protests from Yugoslavia, Romania, China, and from Western European countries.

== Timeline overview == The table below displays all national recessions appearing in 2006–2013 (for the 71 countries with available data), according to the common recession definition, saying that a recession occurred whenever seasonally adjusted real GDP contracts quarter on quarter, through minimum two consecutive quarters. Only 11 out of the 71 listed countries with quarterly GDP data (Poland, Slovakia, Moldova, India, China, South Korea, Indonesia, Australia, Uruguay, Colombia and Bolivia) escaped a recession in this time period. The few recessions appearing early in 2006–07 are commonly never associated to be part of the Great Recession, which is illustrated by the fact that only two countries (Iceland and Jamaica) were in recession in Q4 2007. One year before the maximum, in Q1 2008, only six countries were in recession (Iceland, Sweden, Finland, Ireland, Portugal and New Zealand). The number of countries in recession was 25 in Q2 2008, 39 in Q3 2008 and 53 in Q4 2008. At the steepest part of the Great Recession in Q1 2009, a total of 59 out of 71 countries were simultaneously in recession. The number of countries in recession was 37 in Q2 2009, 13 in Q3 2009 and 11 in Q4 2009. One year after the maximum, in Q1 2010, only seven countries were in recession (Greece, Croatia, Romania, Iceland, Jamaica, Venezuela and Belize). The recession data for the overall G20 zone (representing 85% of all GWP), depict that the Great Recession existed as a global recession throughout Q3 2008 until Q1 2009.
==== Gonadotropin-releasing hormone agonists ==== GnRH agonists are a group of drugs intended to activate GnRH receptors in the anterior pituitary gland. They are synthesized by replacing the sixth and tenth amino acids of the original gonadotropin-releasing peptide hormone. After the modification, they can bind to the GnRH receptors more strongly and are less degradable by enzymes when compared to the natural GnRH, making them more biologically active. GnRH agonists commonly used are leuprorelin, goserelin, and triptorelin, which are marked as Lupron, Zoladex, and Decapetyl, respectively. Nafarelin, marked as Synarel, is also occasionally prescribed in the form of nasal spray. These drugs are all approved by the US FDA, and their working principles target both sexes equally.
So what can it mean when America says it will now protect its friends? It can only mean prejudice against Iraq. This stance plus maneuvers and statements which have been made has encouraged the UAE and Kuwait to disregard Iraqi rights ... If you use pressure, we will deploy pressure and force. We know that you can harm us although we do not threaten you. But we too can harm you. Everyone can cause harm according to their ability and their size. We cannot come all the way to you in the United States, but individual Arabs may reach you ... We do not place America among the enemies. We place it where we want our friends to be and we try to be friends. But repeated American statements last year made it apparent that America did not regard us as friends. Glaspie replied:
=== Female pheromones === cis-7-dodecenyl acetate cis-5-dodecenyl acetate 11-dodecenyl acetate cis-7-tetradecenyl acetate cis-9-tetradecenyl acetate dodecyl acetate Cabbage loopers are unique in that both females and males release pheromones in order to seek a mate. Generally, females release pheromones from the tips of their abdomens, and males seek females upon detection. Females around host plants are more attractive to males, possibly because females release more pheromones in the presence of host plant odor. Although it is not clear why host plant odors incite female pheromone production, this response may help reduce time wasted spent searching for a mate and therefore increase the chance of mating. Female cabbage loopers usually attract the male, as females have more to lose by spending energy and time on searching for a mate.

It acts on the growth hormone–releasing hormone receptor, a Gs-coupled receptor found on pituitary somatotroph cells. Activation raises cAMP and prompts pulsatile hormone release.
IGF-1 reflects growth hormone activity but changes slowly and can be measured from one sample. Growth hormone itself is pulsatile, which makes single measurements hard to interpret.
The receptor pathway is well described, but how individual responses vary and what governs long-term outcomes remain open questions. Reported differences across studies are often attributed to assay and population factors.
It mimics a natural hypothalamic signal that tells the pituitary to release growth hormone. The result is a rise in circulating growth hormone and, indirectly, in insulin-like growth factor 1. Over weeks of treatment this shift is associated with a selective decrease in fat stored inside the abdomen.
