RESUMO

ABSTRACT Objective: The objective of this narrative review is to discuss the current state of research funding in Brazil. Materials and Methods: This study is based on the most recent edition of the course Funding for Research and Innovation in the University of Sao Paulo School of Medicine which was a three-day course with 12 hours of instruction. The course brought together leading experts in the field to comprehensively discuss the current state of research funding in Brazil. Each speaker provided a presentation on a specific topic related to research funding. After the workshop, speakers assembled relevant topics in this manuscript. Results: collaborative research is critical for securing research funding. It optimizes proposal competitiveness, amplifies societal impact, and manages risks effectively. As such, fostering and supporting these collaborations is paramount for both researchers and funding agencies. To maintain the highest integrity in research, investigators involved in these collaborations must disclose any relationships that could potentially influence the outcomes or interpretation of their projects. Conclusions: In Brazil, the mainstay of research funding stems from public entities, with agencies such as CNPq, CAPES, and state bodies like FAPESP, FAPERJ, FAPEMIG and others at the forefront. Concurrently, industry funding offers viable pathways, especially through industry-sponsored studies, investigator-led projects, and collaborative initiatives. The Brazilian funding landscape is further enriched by innovative platforms, including crowdfunding and the contributions of institutions like the Serrapilheira Institute. Internationally, esteemed organizations such as the National Institutes of Health (NIH) and the Bill & Melinda Gates Foundation stand out as potential funders.

RESUMO

This study evaluated the association of polymorphisms of VEGF (endothelial vascular growth factor) gene + 936C/T (rs3025039), 1154 G/A (rs 1570360) and -2578 C/A (rs 699947) in patients with polycystic ovary syndrome (PCOS) and to perform the haplotypes formed by the alleles in the Brazilian population. A total of 110 women without PCOS and 112 women with PCOS were included in the study. Genotyping analyses were performed using the PCR-RFLP assays (rs 3025039 and rs 699947) and by allelic discrimination using the real-time PCR technique (rs 1570360). In the univariate analysis, we observed a significant difference between the groups for the polymorphism rs 1570360 and this polymorphism presented statistical differences between the groups for the recessive model (p = .04). The frequency of the T-G-C haplotype showed a statistically significant difference between women with PCOS and controls (p = .05). The -2578 A/C polymorphism was more frequent in the control group, which may be associated with a protective characteristic for the PCOS manifestation. In the sample analysis, polymorphism rs 1570360 is associated with PCOS and the T-G-C haplotype could be associated with protective factors.

RESUMO

The normal hematological values in various phases of the rat life provide a valuable guide to researchers and could be useful for experimental works. However, database information available on the literature are incomplete. AIM: This study aimed to present normal hematological parameters of young and aged rats. METHODS: Male and female rats were distributed into seven experimental groups with 1, 2, 3, 6, 12, 18, and 24 months of age. Blood samples taken from the tails were analyzed. Normal hematological values were determined for each age group. RESULTS: Rats showed a progressive weight gain with advancing age, predominantly after 3 months of life. With advancing age, differences were found on hematological parameters: some of them showed a progressive rise with age and others did not. Hemoglobin levels and hematocrit did not change while the number of circulating red blood cells suffered slight increase. CONCLUSION: The present study determined the normal values for absolute and relative hematological parameters in Wistar rats from 2 to 24 months for male and female rats. The results can be used in studies of effects of aging, feeding, and medications on growing and aging rats.

RESUMO

Com o intuito de estudar a denervaçäo brônquica na fase crônica da doença de Chagas investigaram-se as propriedades mecânicas e a motricidade brônquica de 6 coelhos chagásicos crônicos e 4 controles. Utilizou-se o método da pletismografia de corpo inteiro e todas as medidas foram feitas antes e depois da administraçäo endovenosa de cloridrato de histamina (0,11 mg/kg). No grupo chagásico crônico obteve-se um menor acréscimo da capacidade residual funcional e uma quase inalteraçäo do pico de fluxo na expiraçäo passiva após a administraçäo de histamina. Este grupo apresentou também um desvio para a direita na curva estática de pressäo transpulmonar/volume. Estes resultados sugerem uma alteraçäo na árvore brônquica, que consiste principalmente numa broncoreatividade diminuída
