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.
The off-label use of human growth hormone (HGH) has spawned a multi-billion dollar industry. Some doctors see it as a fountain of youth, while others are staunchly opposed and fear that the risks far outweigh the potential benefits. The FDA has not approved the use of human growth hormone as an anti-aging therapy.Here, Iâll review what HGH is, how it works, and the pros and cons of use.any of the effects of HGH are brought about through a second hormone, insulin-like growth factor-1, made by the liver. HGH is given by daily injection, and is quite expensive. Alternative treatments, such as the nasal spray or pills to stimulate HGH release, have not been proven to have any benefit.
