Tobacco smoking and human papillomavirus (HPV) are both well-known risk factors for head and neck cancer, but there is ample evidence that they can interact to increase the risk of contracting the disease, according to a study conducted by researchers at the University of So Paulo (USP) in Brazil and the University of Chile. The study was published in the International Journal of Molecular Sciences. The study’s findings shed light on elements of the molecular pathways at work in head [...]

Newborn kids who have low levels of oxygen in their bodily tissues (hypoxia) as a result of sleep apnea, for example, are more likely to have respiratory problems and hypertension (high blood pressure) later in life, and these problems may last the remainder of their lives. According to researchers at So Paulo State University (UNESP) in Brazil, hypertension in these circumstances is caused by dysregulation of the autonomic nervous system, which controls involuntary physiological activities [...]

Sarcopenia is the decrease of skeletal muscle mass with aging, which impairs performance and muscle strength (needed to handle objects, shake hands, etc). (walking and making other routine movements effectively). It involves ongoing inflammation and is linked to mental decline, cardiovascular disease, and respiratory conditions. In essence, it degrades the quality of life by limiting independence and raising the chance of accidents, falls, and even fatalities. 15% of adults over 60 and 46% [...]

Depression affects 10%-16% of pregnant women worldwide. Most get better with the help of antidepressant drugs. Although the safety of using antidepressants during pregnancy is endorsed by science, their effects on fetal neurodevelopment are poorly understood and should be studied with advanced techniques such as genomics. This is the main conclusion reached by a group of Brazilian researchers in a review of more than 100 scientific articles on fetal exposure to these drugs, especially [...]

Scientists affiliated with the Department of Physical Education’s Human Movement Laboratory (Movi-Lab) at São Paulo State University (UNESP) in Bauru, Brazil, are using artificial intelligence to help diagnose Parkinson’s disease and estimate its progression. An article published in the journal Gait & Posture reports the findings of a study in which machine learning algorithms identified cases of the disease by analyzing spatial and temporal gait parameters. The [...]

An article published in Science Advances describes for the first time a neuromuscular circuit that links the burning of muscle fat to the action of a protein in the brain. The findings, obtained in Brazil by researchers at the State University of Campinas (UNICAMP) and the University of São Paulo (USP), contribute to a deeper understanding of how regular physical exercise helps weight loss, reinforcing the importance of this habit to good health. “We set out to study the [...]

Cutting protein intake can help control metabolic syndrome and some of its main symptoms, such as obesity, diabetes, and high blood pressure (hypertension), according to a study conducted by researchers in Brazil and Denmark to compare the effects of calorie and protein restriction diets in humans. An article reporting the study is published in the journal Nutrients. Metabolic syndrome is a cluster of conditions that heighten the risk of cardiovascular disease, stroke, and diabetes, [...]

Researchers at the University of São Paulo (USP) in Brazil analyzed data from 43 scientific articles describing the effects of COVID-19 on athletes and concluded that while the disease was asymptomatic or mild in the vast majority of cases (94%), about 8% of the subjects concerned had persistent symptoms affecting their performance and potentially preventing a return to training and competing. The data they analyzed referred to some 11,500 athletes, including amateurs and [...]
