chasteberry

on the whole a genus of tropical and sub-tropical flowering plants. Mentioned Theophrastus the shrub Several times, as in agnos Enquiry into Plants. It has-been long Believed to be an anaphrodisiac but effectiveness remains controversial.Vitex agnus-castus is Widely cultivated in warm temperate and subtropical regions for its delicate-textured aromatic foliage and butterfly attracting spikes of lavender flowers in late summer in cooler climates. It grows to a height of 1-5 meters. It requires full sun or partial shade Along With well-drained soil. Under perfect conditions it is hardy to 10 degrees.
It is Believed That some of the compounds found in the plant work on the pituitary gland Which would explain its effects on hormonal levels. A study has shown That extracts of the fruit of VAC can bind to opiate receptors; This Could Explain why you reduce intake of VAC PMS discomforts.
The mechanism of action is not fully Understood but it is Assumed that resultanting it has dopaminergic effects of prolactin secretion in Changes. At low doses, Might Have Been: such as used in previous centuries for suppression of sexual desire, it Inhibits activation of dopamine receptor by competitive binding, Causing a slight Increase in release of prolactin. In Concentrations higher, as in modern extracts, the binding activity is sufficient to reduce the release of prolactin. A study has found That treatment of 20 healthy men with higher doses of Vitex agnus-castus was Associated with a slight reduction of prolactin levels, lower doses Whereas Caused a slight Increase as Compared to placebo doses of

Substance P

Substance P is the first neuroactive substance that is proposed as a neurotransmitter. As for the pharmacological properties of substance P, they were demonstrated to check exhibiting potent hypotensive properties that were not blocked by atropine. He was later identified as the first active neuropeptide and was proposed as a neurotransmitter. In the 70s the structure is now known to contain eleven amino acids, of which six corresponding to the C-terminus are essential for its biological activity was determined. Substance P (SP) is a neuropeptide of eleven amino acids, are much smaller than other neurotransmitters amounts, is synthesized in the cell body and transported along the axon to the terminals, it is synthesized as part of a prepropeptide ( preproteins or precursors) of higher molecular weight which then moves to the cisterns of the endoplasmic reticulum, where it is disintegrated to produce a proprotein. The proprotein is transported to the Golgi apparatus, where they may fac...

Alzheimer's disease (AD) has become a growing problem in the medical, psychiatric, neurological, epidemiological, social and economic order, particularly in countries with a high life expectancy Alzheimer's dementia can be classified according to the age of onset in presenile or early onset, which appears before age 65 and senile or late onset, ie onset after age 65. It according to the presence or absence of a family history of the disease is classified into familial AD and sporadic AD, respectively. However, these classifications are not mutually exclusive. The development achieved by genetic has demonstrated the involvement of several chromosomes in the development of the disease. Chromosomes 1, 14 and 21 are associated with familial forms of start precoz. While late onset forms appear linked to chromosomes 12 and 19 In this paper we delved into the study of chromosome 21 and the amyloid beta protein , because there are many findings that relate to deposit excess am...
