Researchers at the University of São Paulo and São Paulo state’s Center for Epidemiological Surveillance observed spatial and temporal patterns of occurrence and co-occurrence for the two arboviral diseases in all Brazilian municipalities, alongside the influence of environmental and socio-economic factors.
Traditional wet markets, the main source of fresh food for the citizens of Hanoi, Vietnam have been tricky to study because of a lack of traceability and sales registration system—but a new study shows how researchers used free Wi-fi to track the flow of over 600,000 people through the markets.
A study involving 20 women with rheumatoid arthritis and high blood pressure demonstrates the benefits of walking at moderate speed for 30 minutes even after tests that simulate stressful situations and tend to raise blood pressure.
A study published in the journal Science shows for the first time the degree of threat to all tree species in the biome, classifying 65% as vulnerable or endangered to some extent. According to the authors, their findings are conservative – the actual situation could be even more alarming.
Even under the best-case scenario, mathematical models suggest 87% of mammals will be left without a habitat in the Caatinga within three and a half decades. The loss will be worst in the eastern portion of the biome, where its main cities are located.
This is the first description of the interaction between microRNAs and gibberellin, especially in as economically important a plant as the tomato. Research conducted at the University of São Paulo shows how interaction between plant hormone gibberellin and small RNA molecules enables development of ovaries, followed by fruit and seeds. A simultaneous rise in the activity of miR156 and gibberellin in the tomato’s floral meristem results in malformed ovaries and misshapen seedless fruit. This knowledge serves as a basis for ways to increase tomato yield.
The device is under preclinical trials; the sponge is made of soft, biodegradable material and releases medication slowly into the organism.The sponge is made of materials that are biocompatible with vaginal tract cells, and the gel produced by contact with fluid in the region dissolves, so that there is no need for removal after the treatment, in contrast with polyurethane devices.
D'Or Institute for Research and Education (IDOR) played an important role in the phase III LIBRETTO-431 multicenter study, which evaluated the efficacy and safety of selpercatinib compared to control treatment, which consisted of platinum-based chemotherapy associated or not with pembrolizumab (immune checkpoint inhibitor) in non-small cell lung cancer (NSCLC). The research was published in the New England Journal of Medicine (NEJM), one of the most important scientific publications in the medical field, and included Dr. Milena Perez Mak, IDOR researcher and clinical oncologist at the São Paulo State Cancer Institute (Icesp).
Published in the scientific journal “Religion, Brain & Behavior”, a study led by the D’Or Institute for Research and Education (IDOR) evaluated and mapped the perceptions of over a thousand spectators participating in the Festival of the Nine Emperor Gods, a celebration that gathers approximately one million people in several Asian countries and has predominantly religious significance. In these events, self-inflicted violence is normalized by a small portion of its participants. The research aimed to map the audience’s reactions to these rituals, seeking to understand the social effects of this cultural event.
Acute Myeloid Leukemia (AML) is a cancer type that originates in the bone marrow. Despite being considered a rare disease, it is the most common type of acute leukemia and progresses rapidly, necessitating immediate treatment. While many advancements have been made in the disease’s treatment, these resources are not fully accessible in underdeveloped countries. This situation has prompted Latin American scientists to seek a comprehensive understanding of AML on their continent, with a primary focus on the therapies and diagnostic methods available for this population.
