Researchers have analyzed the effect of zika virus on the body of laboratory mice, identifying possible damage to the adult brain.

Although adults do not present symptoms, other than skin redness and fever, the frequent connection between zika and Guillian-Barré raised suspicions of possible damage to the adult brain. "We wanted to know if zika has more effects on forming neurons than anywhere else in the adult brain." We found that there is something special in these cells that allows the virus between them and affect their proliferation, "said Joseph Gleeson, one of the authors of the research.

Infectionist Sujan Shresta of the La Jolla Institute collaborated in the study by developing mouse models specifically to understand the action of zika. To do this, it had to stop the action of the antiviral molecules, which would help rodents resist the infection and injected into their bloodstream a current strain of the virus. After three days, the researchers analyzed the mice and used antibodies to identify the presence of zika, discovering that virus particles surrounded neural cells. "We do not know what this means in terms of human disease or whether the cognitive behavior of individuals can be impacted after infection," Shresta says.


Signs in the brain help to diagnose fibromyalgia, says study

Signs in the brain help to diagnose fibromyalgia, says study

A study by researchers of the University of Colorado in Boulder, reported that signs in the brain can help identify fibromyalgia with 93% accuracy. The researchers used functional magnetic resonance imaging (MRI) to study the brain activity of 37 fibromyalgia patients and 35 patients in the control group, according to a study published in the journal PAIN by the International Association for the Study of Pain.

Orthognathic surgery makes bite correction and aesthetic improvement of the face

Orthognathic surgery makes bite correction and aesthetic improvement of the face

The definition of orthognathic surgery comes from the Latin "ortho", which means correct, and "gnatos", which comes from the jaws. That is, it means putting the jaws in their best relationship, to promote facial aesthetics and better occlusion (bite). It is estimated that 25 to 30% of the population presents some degree of facial disharmony and that at least half of this total needs treatment.
