New Delhi, May 4 (PTI) Researchers have analysed microRNAs in extracellular vesicles (EVs), produced by most cells in the body including neurons and other nervous system cells, and found them to be associated with mental health disorders. The study by researchers at the Federal University of Sao Paulo (UNIFESP) in Brazil is published in the journal Translational Psychiatry. MicroRNAs (miRNAs) are small transcripts that target messenger RNAs and regulate the expression of several genes at [...]

A study has found that poor diet has contributed to over 14.1 million cases of type 2 diabetes. The study was published in the journal, 'Nature Medicine.' The analysis, which looked at data from 1990 and 2018, provides valuable insight into which dietary factors are driving type 2 diabetes burden by world region. Of the 11 dietary factors considered, three had an outsized contribution to the rising global incidence of type 2 diabetes: Insufficient intake of whole grains, [...]

New Delhi, April 18 - Poor diet contributed to over 14.1 million cases of type 2 diabetes in 2018, representing over 70 per cent of new diagnoses globally, according to a study. Of the 30 most populated countries studied, India, Nigeria, and Ethiopia had the fewest case of type 2 diabetes related to unhealthy eating, the researchers said. The analysis, published in the journal Nature Medicine, looked at data from 1990 and 2018, providing valuable insight into which dietary factors are [...]

Sau Paulo: An electrochemical sensor that can identify Parkinson's disease at various stages has been created by researchers at the Federal University of So Carlos (UFSCar) and the University of Campinas (UNICAMP) in Brazil. The gadget was created using a standard 3D printer and showed early disease detection capabilities, serving as a model for the detection of other diseases, according to the study. Findings in the journal published in the journal Sensors and Actuators B: [...]

The findings are published in the journal Language Resources and Evaluation. While there are multiple studies involving natural language processing (NLP) focussed on depression, anxiety and bipolar disorder, most of these analysed English texts and did not match Brazilians' profiles, the researchers said. The first step in this study involved constructing a database, called SetembroBR, of information relating to a corpus of 47 million publicly posted Portuguese texts and the network [...]

A team of researchers found that the coronavirus that causes Covid-19 can be detected in tears sampled by ocular swabs, a new study has shown. The researchers analysed samples from patients diagnosed with the disease by conventional methods and admitted to the Hospital, according to the study published in the Journal of Clinical Medicine. SARS-CoV-2 was detected in 18.2 per cent of the samples, suggesting this method could be an alternative to the conventional swabbing method, which is [...]

Washington: Strokes are a leading cause of morbidity and mortality in the United States and globally. Several environmental and biological factors are known to influence stroke risk and outcome. A new study led by investigators from Brigham and Women's Hospital, a founding member of the Mass General Brigham healthcare system, analyzed the cerebral blood flow (CBF) regulation of individuals who had experienced strokes. The team found that cerebral autoregulation (CA) -- one of the key [...]

Scientists have found that the fat around the liver, intestines and other organs, or visceral fat, contributes more towards severe COVID-19 than does subcutaneous fat, or fat under the skin as in “love handles”, according to a study. Visceral fat is usually considered a risk factor for cardiovascular disease, diabetes and high blood pressure. The researchers at the State University of Campinas (UNICAMP) and the University of Sao Paulo (USP) also found that when visceral [...]

Rapid, low-cost, and accurate tests are still required for epidemiological surveillance and healthcare services to monitor and contain the spread of SARS-CoV-2. Brazilian researchers have contributed to this field’s efforts by creating an electrochemical immunosensor that identifies antibodies against the virus. The innovation is described in an article published in the journal ACS Biomaterials Science and Engineering. In search of a novel diagnostic method, the group opted for a [...]
