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

-Definition Interferons are proteins or glycoproteins produced by different cell types in response to various stimuli, including viral infections. Three classes of interferons are distinguished according to their structural and biological characteristics: interferon alpha or leukocyte type, interferon beta or fibroblastic type and interferon gamma or immune type, produced by T lymphocytes and natural killer cells. Interferons α, of which several subtypes have been identified, are non-glycosylated polypeptides, while interferons beta, gamma and kappa are glycosylated polypeptides. Alpha and beta interferons are produced by monocytes, leukocytes, lymphocytes in response to […]

-Definition Mumps, commonly referred to as mumps, is the inflammation of salivary glands called parotids located behind the ascending branches on both sides of the jaw and is produced by an RNA virus belonging to the paramyxovirus family. It is one of the most common notifiable viral infections. The only reservoir is the human being and the transmission is aerial so the outbreaks occur mainly in closed places. Although the infection is asymptomatic in a third of cases, the most frequent clinical manifestation is inflammation of the parotid or other […]

-Definition Too much iron in the blood can lead to testicular failure or pituitary dysfunction, which affect testosterone production. Pituitary and testicular involvement is the cause of loss of menstruation in women or loss of libido and impotence in men. Hypothyroidism may be observed, in addition to affecting various organs. -Causes of the disease Congenital Hereditary hemochromatosis is the most common genetic disease in the West, affecting 1 in 200 people. All studies have shown its higher prevalence in Caucasian and Celtic individuals. The inheritance of the disease is autosomal […]

-Definition: It is a sexual accessory gland to the male reproductive system whose shape and size resembles, in young adults, a chestnut or walnut, weighing approximately between 12 and 20 grams. It is located below the bladder, next to the beginning of the urethra, which surrounds behind the pubis and in front of the anal canal. Its conformation resembles a sponge, formed by thousands of small cavities where a secretion is formed, and through multiple very fine ducts, is poured into the so-called prostatic urethra.It is important that the prostatic […]

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

On October 21, 2018, the New York Times published “’Transgender’ Could Be Defined Out of Existence Under Trump Administration,” in which journalists Erica L. Green, Katie Benner, and Robert Pear wrote that the “administration is considering narrowly defining gender as a biological, immutable condition determined by genitalia at birth, the most drastic move yet in a governmentwide effort to roll back recognition and protections of transgender people under federal civil rights law. The press releases below, from WPATH and our US regional chapter, USPATH, present this Association’s immediate response. Further […]

Definition: Gestational diabetes is defined as a carbohydrate intolerance that can be of varying severity and that is initiated or first identified during pregnancy. Gestational diabetes is diagnosed in 9-14% of pregnant women. The criteria used for diagnosis are pregnancy-specific and differ from those used for the diagnosis of diabetes or glucose intolerance outside of pregnancy. The American Diabetes Association recommends that pregnant women be screened for gestational diabetes at 24-28 weeks of gestation with a 50 g oral glucose overload test and 1 hour blood glucose determination, which is […]

Xenoandrogens as hormone disruptors

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

-Xenoandrogens: Were first described in 2008 by Professor I. Morishita of Kyoto University and his team. His scientific work described how modified all alpha-tocopherol acetate racemic stimulates receptor AR in some mammalian species. What about Xenoandrogens?: are a group of artificially created compounds with properties similar to the human steroid hormone testosterone and its derivatives. Currently known xenoandrogens include modified tocopherols and tocotrienols, modified nicotinamides and tributyltin, triphenyltin, and toxic methylestestosterone. -Use to increase yield: They were not commercially available until the second half of 2011, but some professional athletes […]

CRISPR and the genome

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

-Introduction: CRISPR technology is a recent genome-editing tool that acts as molecular scissors capable of specifically cutting any sequence of DNA from the genome and allowing the insertion of changes in it. Its origin is in a microorganism that inhabits the marshes of Santa Pola (Alicante), in whose genome the biologist Francis Mojica, in 1992 found the bases that would give rise to the CRISPR technique. This genetic editing tool, the most powerful ever discovered, is applicable to fields such as Agriculture, Livestock, Biotechnology and Medicine. There are regions of […]
