“To change sex, the first transformation is at the hormonal level. If you want to act in a more radical way you have to intervene at the surgical level. Hormones I’m very responsible of our appearance. In a male organism, hormones must be inhibited to reduce the male presence. And then the feminine ones are introduced and here the beard decreases, the skin becomes smoother and the breasts grow. On the contrary, if you want to become a man from a woman you have to do the opposite “, says the biologist Barbara Gallavotti guest as always in the studios of Tuesday broadcast on La7 and hosted by Giovanni Floris.
Floris then asks him about the surgery: “It means adapting the sexual organs to the appearance you feel there. Building a vagina or penis. A non-trivial intervention, which must be done by expert hands. It takes a psychological confrontation first. It is not possible to modify one’s body in order to have children. Difficult changes are the voice and the Adam’s apple“explains Gallavotti.
Then there is talk of puberty and the administration of the injection to adolescents to change the sex, Triptorelin: “It is not a drug to change the sex, but it only delays puberty. It is used to give time to a boy or a girl who feels she belongs to a different gender from the one where her body goes, to think, reflect and mature and in any case it is recommended by specialists and is also a life-saving drug. Triptorelin“, explains Gallavotti in front of the questions of the program host.
The biologist Barbara Gallavotti, regular guest of Giovanni Floris a Tuesday, on La7 explains the news on the coronavirus discoveries from Israeli researchers who have published a study on Nature. The question from which the research starts is: “Why is coronavirus a winner among infectious agents?”. So Gallavotti explains: “The coronavirus aims to take control of the cell, in particular its production system, and to force the cell to produce the coronavirus proteins which then assembled as in a Lego form the new infectious agent. “.
The cell, however, continues Gallavotti, “has security systems and chemically reacts by producing molecules that on the one hand hinder the virus inside it and on the other go outside the cell and warn the immune system. Like when in besieged cities. they came send messengers outside to call the allies to help “. Unfortunately, however, explains the biologist,”this mechanism with the coronavirus does not respond to the best“.
What happens “is that when the cell realizes the presence of the invader tries to activate the genetic information aimed at countering the virus that is in its DNA and therefore in order for this emergency information to be brought to the production plant it must be transcribed in an Rna molecule and this should exit the nucleus and head towards the factory proteins “. In short, as in war,” there is a head to head between the RNA of the virus and that of the cell and the goal is to be the first to arrive at the cell’s operations center and put it at your service. Whoever manages to win has one more point. As in a game of chess “. Unfortunately, however, concludes Gallavotti,” it has been seen that in most cases the new coronavirus manages to checkmate to the cell and get to the protein factory first and that gives it a huge advantage. ”
