Research points to correlation between preeclampsia and COVID-19 in pregnant women
Publicado em 08 de novembro de 2024
During the COVID-19 pandemic, above all before vaccines were available, an alarm was sounded regarding a possible correlation between severe cases of COVID-19 in pregnant women and preeclampsia, a condition characterized by high blood pressure (hypertension) in the expectant mother and high levels of protein in her urine (proteinuria). It can entail dangerous complications for mother and baby.
Preeclampsia was more frequent in pregnant women infected by SARS-CoV-2 and was associated with a [...]

Light Physical Activity Linked to Improved Vascular Parameters in RA
Publicado em 06 novembro 2024TUESDAY, Nov. 5, 2024 (HealthDay News) -- Sedentary behavior (SB) is negatively associated and light physical activity (PA) is positively associated with vascular parameters among postmenopausal women with rheumatoid arthritis (RA), according to a study published online Nov. 1 in theAmerican Journal of Physiology: Heart and Circulatory Physiology. Kamila Meireles, from the Universidade de São Paulo in Brazil, and colleagues conducted a cross-sectional study involving 82 postmenopausal [...]ver notícia -
Water overuse in Brazil's MATOPIBA region could mean failure to meet up to 40% of local demand for crop irrigation
Publicado em 05 novembro 2024Considered one of the fastest-growing agricultural frontiers in Brazil, and the area with the highest greenhouse gas emissions in the Cerrado, Brazil's savanna-type biome, the region known as MATOPIBA, risks facing water shortages in the years ahead. Water overuse may mean that between 30% and 40% of demand for crop irrigation cannot be met in the period 2025-40. MATOPIBA is a portmanteau of the names of four states—Maranhão, Tocantins, Piauí, and Bahia (all but [...]ver notícia -
Study reveals the role of eye movements in Parkinson's disease
Publicado em 01 novembro 2024Rapid side-to-side eye movements can help stabilize posture, avoid falls and maintain balance for people with Parkinson's disease, just as they can for healthy people. This seemingly counterintuitive conclusion was reached by researchers at São Paulo State University (UNESP) in Brazil and the University of Lille in France in a study supported by FAPESP. An article on the study is published in the journal Biomechanics. Ten individuals diagnosed with Parkinson's and 11 [...]ver notícia -
Study identifies 51 amyotrophic lateral sclerosis-associated mutations that could help diagnose the disease
Publicado em 31 outubro 2024Using sequencing techniques, researchers associated 51 mutations in mitochondrial DNA with amyotrophic lateral sclerosis (ALS), an incurable degenerative neurological disorder that leads to muscle atrophy and paralysis. Thirteen of the mutations increased the risk of ALS, while 38 were protective. The study suggests these mutations may be important for future tests and research on ALS. It is worth recalling that mitochondria, the organelles that produce energy for cells, have their own DNA [...]ver notícia -
Rapid horizontal eye movement can improve stability in people with Parkinson's
Publicado em 30 outubro 2024A representation of postural tasks and visual conditions: (a) horizontal saccadic eye movements, (b) fixation, (c) vertical saccadic eye movements, (d) feet in side-by-side stance, and (e) tandem stance. The red dot is the target for eye movement tasks. Credit: Biomechanics (2024).

Microplastics have been found in the human brain. Now what?
Publicado em 13 outubro 2024Microscopic pieces of plastic have been found in waterways, in the air, in our feces, and now, in our brains. A study published last month in the scientific journal JAMA Network Open discovered microplastics in the olfactory bulb of human brains of dead patients. Its the first time these plastics have been found in this region of the brain. We are surrounded by plastics, from our clothes to objects around us to our food packaging, said Thais Mauad, associate professor of pathology at So [...]ver notícia -
New dengue virus naming system can help identify and track variants
Publicado em 10 outubro 2024Genomic surveillance of the evolving SARS-CoV-2 virus has been essential for managing the COVID-19 pandemic, helping researchers identify new variants, track their circulation, and create new vaccines that target the most common emerging variants. The same approach is applied when developing annual flu shots. This work, however, requires a structured naming system for new variants so that everyone studying and tracking viruses can be on the same page, speaking the same language. To date, [...]ver notícia -
Asteroid that wiped out the dinosaurs may have led to the invention of 'ant agriculture'
Publicado em 07 outubro 2024The event that wiped out the dinosaurs wasn't all bad. The low-light environment caused by the meteor impact some 66 million years ago favored the spread of fungi that feed on organic matter, which was abundant at the time as plants and animals were dying in droves. It was the perfect opportunity for the ancestor of a group of ants to start cultivating these microorganisms, according to a study published on October 3 in the journal Science "The origin of fungus-farming ants was [...]ver notícia -
Scientists discover how ants took advantage of asteroid that wiped out the dinosaurs
Publicado em 04 outubro 2024Ants started farming 66 million years ago in the aftermath of the asteroid that wiped out the dinosaurs, a new study suggests. Colonies of ants began farming the fungi as it experienced “a heyday”, according to scientists. The asteroid created ideal conditions for them to thrive, despite causing global mass extinction. Researchers say many animals have been growing their own food since long before humans existed. Ted Schultz, curator of ants at the Smithsonian’s [...]ver notícia
