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 is an essential hormone produced by the body in small amounts throughout the life span. It is most important, however, in young people as it is critical for linear growth (height). The most common use for human growth hormone is therefore in young people who are short, either because of genetics or because of an underlying medical problem. This is the only use of growth hormone for which there is good evidence. The treatments are very expensive, but they do lead to an increase in height in this population. There have been some experimental uses of growth hormone in the elderly to reverse some of these features of aging.
