Study suggest Brazilian plant compound may be key to treating kala-azar
Publicado em 08 janeiro 2025
Kala-azar or visceral leishmaniasis -- a deadly neglected tropical disease -- can be better treated using a compound derived from Nectandra leucantha -- a tree native to southern Brazil (local names: canela-seca or canela-branca), claimed a study.
Kala-azar is caused by a protozoan parasite transmitted by a sandfly bite and is characterised by long bouts of fever, loss of weight and muscle strength, enlargement of the spleen and liver, and anaemia.

Researchers propose treatment strategy to make fighting cancer easier
Publicado em 01 julho 2024A novel treatment strategy involving a combination of two drugs has shown promising results in suppressing tumours by an unconventional method. The new approach, detailed in the journal Cancer Discovery, includes LB-100, currently in clinical trials for lung tumours, and WEE1 inhibitors, which prevent tumour DNA repair. The drug combo works by hyperactivating cancer cells to induce stress, making them more susceptible to targeted attack. The study reveals that the treatment's [...]ver notícia -
Vegan diet may lower risk of eating disorders: Study
Publicado em 29 setembro 2023People who follow vegan diets have low risk of eating disorders, finds a study. The team at University of Sao Paulo (USP) in Brazil used an online questionnaire to collect socio-demographic data (such as education, income and location, among others) and information on eating habits for 971 participants aged 18 or older from all parts of Brazil. Analysing the data, they were able to arrive at the percentage of vegan diet followers reporting dysfunctional dietary behaviour and therefore, [...]ver notícia -
Covid virus alters RNA in infected cells, shows study
Publicado em 10 novembro 2022For the first time, scientists have shown that infection by Covid virus changes the functioning of host cell RNA, providing clues as to how different variants can escape the immune system, and serve as a basis for the development of novel treatments. Researchers at Federal University of Sao Paulo (UNIFESP) in Brazil arrived at this conclusion by analyzing 13 datasets obtained during four studies of viral, human and animal cell RNA. The study, published in Frontiers in Cellular and [...]ver notícia -
Saliva can predict excess body fat in teenagers
Publicado em 19 fevereiro 2020Rio de Janeiro, Feb 19 | In addition to keeping the mouth moist and protecting us against germs, saliva can also be used for early detection of the risk of developing diseases associated with surplus body fat, a new study suggests. For the findings, published in the journal Nutrition Research, the researchers in Brazil performed a study in which they used the level of uric acid in saliva to predict body fat percentages in teenagers and identify those with surplus fat even if they had no [...]ver notícia -
Lipid in humans can help control blood sugar
Publicado em 29 setembro 2019Sao Paulo : A team of global researchers has discovered that a lipid — produced in response to cold by brown adipose tissue in the human body — helps reduce blood sugar. The discovery with the lipid known as 12-HEPE can pave the way for new treatments for diabetes, said the team from Brazil, the US and Germany. The group also observed that a drug used to treat urinary dysfunction increases the amount of 12-HEPE released into the bloodstream in human patients. White adipose [...]ver notícia -
Low-calorie diet may improve cell performance
Publicado em 13 fevereiro 2019Consuming low-calorie food may have a protective effect against some diseases as the number of calories a person eats directly influences the performance of various cells, researchers say. The study on mice showed that a low-calorie diet can protect the brain from neuronal cell death associated with diseases such as Alzheimer's, Parkinson's, epilepsy and cerebral vascular accident (CVA). "We are looking at how changes to the diet affect metabolism and how that ends up changing the odds of [...]ver notícia -
Cannabidiol effective against depression: Study
Publicado em 01 setembro 2018Sao Paulo, Sep 1 (IANS) A single dose of cannabidiol -- a non-intoxicating compound of marijuana -- was found highly effective in eliminating the symptoms of depression in rats, finds a study. The findings showed that as compared to the commercial anti-depressants that typically take two to four weeks to have a significant effect, cannabidiol's first results appear in 24 hours after a single dose. Moreover, the beneficial effects were fast acting and sustained, persisting for seven days. It [...]ver notícia -
Novel AI-based platform diagnoses Zika with 95% accuracy
Publicado em 14 junho 2018Sao Paulo: Brazilian scientists have developed an artificial intelligence (AI) platform that can diagnose Zika and other pathogens from patients’ blood with over 95 per cent accuracy. The method combines mass spectrometry, which can identify tens of thousands of molecules present in blood serum, including lipids, peptides, and fragments of DNA and RNA, with an AI algorithm capable of finding patterns associated with diseases of viral, bacterial, fungal and even genetic origin. A mass [...]ver notícia -
Young men more vulnerable to mental illness than women
Publicado emYoung men are more likely to experience first-episode psychosis, defined as the first manifestation of one or more severe mental disorders including schizophrenia, bipolar affective disorder, and depression, compared to women of the same age group, says a new study. The findings published in the journal JAMA Psychiatry also showed that ethnic minorities and people living in socioeconomically disadvantaged areas are also vulnerable to severe mental illness. For the study, the researchers [...]ver notícia
