Administering melatonin via an absorbable sponge improved the effectiveness of autologous ovarian tissue transplantation. This procedure is used to preserve the fertility of children and adolescents who have undergone cancer treatment, as well as patients with contraindications or insufficient time for hormonal stimulation and egg retrieval. These findings are from research supported by FAPESP and conducted by scientists from the Department of Obstetrics and Gynecology at the University [...]

A study supported by FAPESP shows that small doses of the antibiotic minocycline may help treat panic disorder. Experiments conducted at São Paulo State University (UNESP) in mice and at the Federal University of Rio de Janeiro (UFRJ) in humans showed that minocycline has a similar effect to clonazepam, the most commonly prescribed anti-panic medication and best known by its brand name, Rivotril. The study was published in the journal Translational Psychiatry. The antibiotic doses [...]

A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus that causes COVID-19. The species was chosen because the research group led by Jairo Kenupp Bastos , a pharmacist and professor at the Ribeirão Preto School of Pharmaceutical Sciences at the University of São Paulo (FCFRP-USP) who coordinated the study, has extensive [...]

A study conducted in the Brazilian state of Amazonas with support from FAPESP demonstrated that small amounts of Amazonian dark earth (ADE) – an anthropogenic soil created by ancient Amazonian populations – can increase the height and diameter of the pink trumpet tree (Handroanthus avellanedae) by up to 55% and 88%, respectively. This tree also occurs in the Atlantic Forest. For the Brazilian firetree (Schizolobium amazonicum), the increase was 20% in height and 15% in trunk diameter. [...]

In addition to habitat loss and illegal hunting, the jaguar (Panthera onca) faces another threat that increases its risk of extinction in the South American Atlantic Forest: food scarcity. A study by Brazilian researchers found that the availability of jaguar prey is reduced, even in the protected areas of the biome, which covers approximately 15% of Brazil and extends across 17 states in the South, Southeast, and Northeast regions, as well as parts of Argentina and Paraguay. Jaguar [...]

A recent randomized clinical trial conducted at Brazil's Botucatu School of Medicine has revealed that a simple daily supplement of vitamin D can significantly enhance the effectiveness of chemotherapy for breast cancer patients. In this phase II study, women receiving neoadjuvant chemotherapy—treatment administered before surgery to shrink tumors—saw their chances of achieving a pathological complete response, where no detectable cancer remains, increase dramatically. This finding [...]

A new study has found that diets high in ultra-processed foods (UPFs) could be quietly undermining brain function, even among people who otherwise follow healthy eating patterns. The data analysed from more than 2,100 dementia-free Australians, who were middle-aged and older, found that a diet high in heavily processed foods can negatively impact the brain's ability to focus, and increase the risk of developing dementia. The research, led by Monash University, found that even modest [...]

In neurological intensive care, it is quickly learned that the brain cannot wait. As the most sensitive organ in the human body, it can sustain irreversible damage after just a few minutes of severe hypoxia. By comparison, a muscle can withstand hours without oxygen. To prevent neuronal damage, action must be taken quickly and precisely. In this scenario, medical decisions are often based on the indicators displayed on the monitors in the intensive care unit (ICU). Clinical experience can [...]

A large Australian study suggests that even modest increases in ultra-processed food intake may affect attention and pathways linked to dementia risk, independent of overall diet quality. Ultra-processed food (UPF) consumption is associated with poorer attention and higher scores on a modifiable dementia-risk index in dementia-free Australian adults aged 40–70 years, according to a cross-sectional study published in the journal Rising ultra-processed food intake raises brain health [...]
