Sorption and pervaporation of tetrahydrofuran (THF) with different concentrations (0.44â11.3 wt.%) in water were studied under various conditions like feed concentration, temperature etc. Permeation factor and activation energy as a function of feed concentration were also studied in this work.
Growth hormone (GH or HGH), also known as somatotropin or somatropin, is a peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals. It is a type of mitogen which is specific only to certain kinds of cells.n recent years in the United States, some doctors have started to prescribe growth hormone in GH-deficient older patients (but not on healthy people) to increase vitality. While legal, the efficacy and safety of this use for HGH has not been tested in a clinical trial.
Human growth hormone (hGH) is a long chain amino acid molecule produced by the anterior pituitary gland, located at the base the brain. It is a large fragile protein molecule with a molecular weight of 20,000. HGH acts on many different tissues to promote healthy metabolism. The bulk of the effect accomplished by hGH is performed by a related hormone called Insulin-like Growth Factor-1 (IGF-1), which is released predominantly by the liver and, to some extent, by other tissues in response to the presence of hGH.
