Brasilia [Brazil], May 26 (ANI): A research group at Sao Paulo State University (UNESP) has analyzed how Candida albicans fungi and Staphylococcus aureus bacteria influence gene expression and tumour cell survival. An in vitro study conducted by researchers at UNESP in Araraquara, Brazil, shows how fungi and bacteria can activate genes associated with head and neck tumours, as the metabolism of biofilms (communities in which these microorganisms self-organize in a structured and coordinated [...]

Rio de Janeiro: In addition to keeping the mouth moist and protecting us against germs, saliva can also be used for early detection of the risk of developing diseases associated with surplus body fat, a new study suggests. For the findings the researchers in Brazil performed a study in which they used the level of uric acid in saliva to predict body fat percentages in teenagers and identify those with surplus fat even if they had no symptoms of chronic obesity-related disease.

According to the scientists, the sympathetic nervous system, which triggers the body's rapid involuntary response to dangerous situations, is affected directly by the stress, and consists of nerves that branch from the spine and run throughout the body. Researchers have identified for the first time the mechanism by which chronic stress causes hair colour loss, an advance that may lead to the development of novel drugs which can prevent the whitening of hair. In the study, published [...]

Stress while driving is a risk factor for the development of cardiovascular disease and sudden cardiac complications such as heart attack, but now researchers have found that listening to music while driving can reduce cardiac stress. "We found that cardiac stress in the participants in our experiment was reduced by listening to music while they were driving," said study lead author Vitor Engracia Valenti, Professor at Sao Paulo State University in Brazil. For the study, [...]
