Sexual differentiation: male or female?

By: | Tags:

What happens in the embryo The sexual differentiation in the human embryo is in itself the differentiation in the masculine sense, since the sex by default is the feminine; this means that in order for the masculine embryo to develop, the natural path that would lead the embryo to differentiate itself in the feminine sense must be deviated. This is achieved from the product of a gene, the SRY gene, found in the Y chromosome of males, which among its most important actions, stimulates the persistence of the primary sexual […]

Antiestrogens in the Clinic

By: | Tags: , , , , , , , , , , ,

They are called antiestrogens to a group of drugs that have the characteristic of inhibiting the action of estrogens. This action is achieved through the union of these substances to estrogen receptors blocking them. These are found in the cells of sensitive tissues. When they enter the receptor, they prevent estrogens from occupying it, thus preventing the action of them, another mechanism of action is through the inhibition of estrogen production by enzymatic blocking of aromatase. -Classes according to action mechanism: -Group 1: They are called selective estrogen receptor modulators […]

It is an alteration of a relatively small part of the brain called the hypothalamus, which although integrated into the nervous system has an endocrine function. In this way it exercises control over the pituitary gland and regulates many bodily functions. Keeping the balance of bodily functions, in such a way is the regulator of: Appetite and weight Body temperature Childbirth Emotions, behavior, memory Growth Breastfeeding The balance of salt and water Sexual desire or libido The cycle of sleep and wakefulness and what is called the circadian rhythm (that […]

cytokines and obesity

Overexpression of kidney androgen-regulated protein (KAP) in the kidney prevents weight gain from eating a high-fat diet. A study led by Dr. Anna Meseguer, head of the CIBBIM-Nanomedicine group Renal Physiopathology of the Vall Research Institute d´Hebron (VHIR) has demonstrated the role of the KAP protein in the control of the development of the metabolic syndrome produced by the ingestion of a diet rich in fat. The generation of a transgenic mouse model in which the KAP gene is specifically overexpressed in the cells of the renal proximal tubule, the […]

An Update on the Exoma:

By: | Tags:

-Exome concept: The exome is the part of the genome (set of DNA molecules) formed by exons, the fragments of DNA that are transcribed to give rise to proteins, the non-coding parts are called introns. The study of exome is one of the most complete and complex ways to study our DNA. A gene is the unit of genetic material that provides the information necessary for the synthesis of a protein. A gene is formed by a long chain of nucleotides, in which exons and introns are distinguished. The exons […]

Antidepressants that do not cause sexual dysfunction

By: | Tags:

-The antidepressant treatment: Although it is effective in improving the manifestations of depression, it may also be able to induce or exacerbate some symptoms of sexual dysfunction, these symptoms negatively affect the quality of life of the subject who suffers and their self-esteem and may lead to non-compliance with the treatment and, consequently, to relapse of depressive symptomatology. The frequency of sexual dysfunction associated with the treatment of adverse effects on sexuality associated with different antidepressants is important, since some are more associated with this problem and others are relatively […]
