Continuous assessment in medical education: Exploring students' views on the progress test.

The Progress Test (PT) is a valuable tool for the continuous assessment of medical students' learning. This quantitative, cross-sectional study aimed to understand the perceptions of 908 medical students (702 from a private and 206 from a public institution) in São Paulo, Brazil, regarding the design and implementation of PT. Analysis included descriptive statistics, Spearman's correlation, Pearson's Chi-square test, and Fisher's exact test.

Prior intake of Brazil nuts attenuates renal injury induced by ischemia and reperfusion.

Introduction: Ischemia-reperfusion (IR) injury results from inflammation and oxidative stress, among other factors. Because of its anti-inflammatory and antioxidant properties, the Brazil nut (BN) might attenuate IR renal injury.

Objective: The aim of the present study was to investigate whether the intake of BN prevents or reduces IR kidney injury and inflammation, improving renal function and decreasing oxidative stress.

Skin secretion peptides: the molecular facet of the deimatic behavior of the four-eyed frog, Physalaemus nattereri (Anura, Leptodactylidae).

Rationale: Amphibians can produce a large amount of bioactive peptides over the skin. In order to map the precise tissue localization of these compounds and evaluate their functions, mass spectrometry imaging (MSI) and gene expression studies were used to investigate a possible correlation between molecules involved in the antimicrobial defense mechanisms and anti-predatory behavior by Physalaemus nattereri.

Methods: Total skin secretion of P.
