Gallium is a by-product of aluminum extracted during the processing of bauxite into alumina. It can also occasionally be found in Zn ore. We are a refiner and supplier of gallium materials. Gallium and gallium alloys are desirable because of their low melting points and wetting properties. They are used for thin-film coatings and in thermal interface materials. Gallium is also used in many semiconducting applications, such as photovoltaics, diodes, and integrated circuits.
Serotonin and melatonin are both neurotransmitters derived from the essential amino acid tryptophan, found in protein. These brain messengers are important for regulating our sleep cycles and our moods.ryptophan is a precursor for 5-HTP, which is subsequently a precursor serotonin and melatonin. Therefore, tryptophan or 5-HTP may be consumed or supplemented to increase levels of both serotonin and melatonin in the body.
Types of sleep disorder. 1. Delayed sleep phase type: Since this is a circadian rhythm sleep disorder, the potential for melatonin to advance the onset of sleep is high. Typical doses of melatonin are 2.5 mg to 3 mg in children, and 5 mg to 10 mg in adolescents. Melatonin is administered from 30 min to 60 min prior to the desired bedtime. However, studies in the use of melatonin for delayed sleep phase type disorder are typically open-label or carried out in adults. 2.
