A team of researchers has for the first time discovered hybrid fungus involved in lung infections and are investigating the role of fungi in COVID-19. Several COVID-19 patients have died owing to concomitant infection by Aspergillus. Aspergillus latus, a species of fungus previously found only in soil or plants, has been found for the first time in a hospital environment by an international group of researchers. The group sequenced its genome and discovered that it is actually a hybrid and [...]

Rio de Janeiro, Feb 19 | 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, published in the journal Nutrition Research, 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 [...]

In a recent study, scientists have discovered that growth hormone (GH) plays an important role when it comes to losing and maintaining weight. According to the research published in the journal Nature Communications, GH stimulates skeletal maturation and linear bone growth, as well as helps maintain tissue and organs throughout life, also acts directly on the brain to conserve energy when the body loses weight.

Diet consisting of fewer calories can improve cell performance, a recent study suggests. The result of the study suggests that the number of calories a person eats directly influences the performance of different cells. "We are looking at how changes to the diet affect metabolism and how that ends up changing the odds of having diseases associated with aging, said Alicia Kowaltowski, lead author of the study. One of the group's experiments on mice shows how a low-calorie diet can protect the [...]

Restaurants across the world serve oversized meals, reported a study conducted by an international team of researchers and supported by FAPESP - So Paulo Research Foundation.

Sao Paulo, Sep 25 (IANS)  Brazilian scientists have identified four new families of extremely young asteroids, taking the total number to 13. The four families, all of which are less than seven million years old, orbit between Mars and Jupiter as part of a grouping known as the Main Asteroid Belt. The researchers dated the families using a numerical simulation method to process current data to go back in time to the asteroid formation era. "We identified the new families by means of [...]

Sao Paulo, Sep 1 (IANS) A single dose of cannabidiol -- a non-intoxicating compound of marijuana -- was found highly effective in eliminating the symptoms of depression in rats, finds a study. The findings showed that as compared to the commercial anti-depressants that typically take two to four weeks to have a significant effect, cannabidiol's first results appear in 24 hours after a single dose. Moreover, the beneficial effects were fast acting and sustained, persisting for seven days. It [...]

Young men are more likely to experience first-episode psychosis, defined as the first manifestation of one or more severe mental disorders including schizophrenia, bipolar affective disorder, and depression, compared to women of the same age group, says a new study. The findings published in the journal JAMA Psychiatry also showed that ethnic minorities and people living in socioeconomically disadvantaged areas are also vulnerable to severe mental illness. For the study, the researchers [...]

When it comes to testing moms-to-be for the presence of Zika, a single negative result may not be enough.   "We monitored a group of pregnant women with a confirmed diagnosis of Zika and tested their urine over a period of several months at intervals of about a week. In some of these women, the viral load in their urine disappeared and later returned," said principal investigator Maurcio Lacerda Nogueira from the FAMERP - Medical School of Sao Jose do Rio Preto, Sao Paulo State. The [...]
