Research conducted at the University of São Paulo involving 95 volunteers associated poor sleep quality with a deterioration in the complications caused by aging and overweight, such as anxiety, depression, body fat gain, and loss of muscle mass and strength.
First of its kind sourcebook provides step-by-step guide to ensure food and agriculture policies have the best chance of success according to national and local contexts.
Recently published in the JCO Global Oncology, an article presents the development of artificial intelligence (AI) for the accurate detection of potentially cancerous nodules described in computed tomography (CT) reports, conducted outside of the cancer screening context. The technology is a Natural Language Processing (NLP) tool, trained to analyze chest CT reports. The study was conducted by the D'Or Institute for Research and Education (IDOR), in partnership with the Federal University of Health Sciences of Porto Alegre (UFCSPA), and the Universities of Florida and Stanford in the United States.
Lurking inside the crops of banana-producing-areas in east and central Africa is a disease called Banana Xanthomonas Wilt (BXW)—and new modeling by researchers from the Alliance of Bioversity International and CIAT has shown that if left uncontrolled, this bacterial disease could cause a 55% reduction in banana production in newly affected regions within 10 years.
Researchers at the University of São Paulo showed in mice the importance of the signaling pathway mediated by the pro-inflammatory cytokine TNF-α and its receptor TNFR1; the discovery could now help scientists develop medications for oral health.
The Smithsonian Bird Friendly coffee and cocoa certification program opened its new Latin American office at the Smithsonian Tropical Research Institute, STRI, in Panama, making it easier for regional coffee and chocolate industries to join the global movement to produce sustainable coffee and chocolate.
Brazilian researchers screened 160 compounds known to be effective against SARS-CoV-2 and identified those that also act against the protozoan parasite Toxoplasma gondii. The most promising will be tested in humans for treatment of the chronic form of the disease.
The study was conducted by researchers at the University of São Paulo, highlighting the importance of identify and isolating infected patients on admission to the emergency room. The findings also showed that containment may be impaired if patients stay more than two days in the ER.
A joint study by researchers from the D’Or Institute for Research and Education (IDOR), the Hospital Sírio Libanês, the Instituto do Coração (InCor), the Instituto do Câncer do Estado de São Paulo, both from the Hospital das Clínicas of the University of São Paulo Medical School and the Centro Paulista de Oncologia - Oncoclínicas, analyzed the relationship between sympathetic neural overload and exercise capacity in patients with heart failure with reduced ejection fraction (HFrEF) related to anthracycline chemotherapy. The study was published in the American Journal of Physiology-Heart and Circulatory Physiology.
A newly described coccolithophore species, Calciopappus curvus was recently found in 2020 in the Sargasso Sea near Bermuda by scientists affiliated with the Bermuda Institute of Ocean Sciences. This newly named species has also been observed prior to its discovery off Bermuda in water samples from far-flung locations as the North Atlantic to tropical and subtropical regions of the Mediterranean, the Atlantic, Indian, and Pacific Ocean. Formally named Calciopappus curvus, is described in a new paper published in the October edition of the journal Protist.
