Alcohol consumption in college students from the pharmacy faculty.

Alcohol consumption is highly prevalent in university students. Early detection in future health professionals is important: their consumption might not only influence their own health but may determine how they deal with the implementation of preventive strategies in the future. The aim of this paper is to detect the prevalence of risky alcohol consumption in first- and last-degree year students and to compare their drinking patterns.

Challenges in clinical-pathologic correlations: acute tubular necrosis in a patient with collapsing focal and segmental glomerulosclerosis mimicking rapidly progressive glomerulonephritis.

Herein, we report a case of acute kidney injury (AKI) due to diarrhea-induced acute tubular necrosis (ATN) in a patient with nephrotic syndrome secondary to biopsy-proven collapsing focal and segmental glomerulosclerosis (FSGS). The clinical picture mimicked rapidly progressive glomerulonephritis (RPGN) and motivated pulse therapy with methylprednisolone and cyclophosphamide. The case presentation is followed by a brief overview of the epidemiology of AKI in nephrotic syndrome as well as a discussion of its risk factors and potential mechanisms involved.

MDMA (ecstasy) delays pubertal development and alters sperm quality after developmental exposure in the rat.

3,4-Methylenedioxymethamphetamine, MDMA or "ecstasy" is consumed mainly by young population at childbearing age. Therefore, there may be a risk of exposure of some pregnant women. The effects of the developmental exposure to MDMA on the sexual development and long-term sexual behaviour/fertility were assessed in Sprague-Dawley rats.

Chronic exposure to MDMA (ecstasy) increases DNA damage in sperm and alters testes histopathology in male rats.

3,4-Methylenedioxymethamphetamine (MDMA or "ecstasy") is consumed mainly by young population. For this reason, it is especially relevant to take into consideration the effects on the reproductive system. The influence of MDMA on the fertility and reproduction of the male rat was assessed in this study.

Determination of aflatoxins in medicinal herbs by HPLC. An efficient method for routine analysis.

A fast and easy to perform method for the routine determination of aflatoxins in medicinal herbs was developed. The described method involves a single-step extraction with a non-chlorinated solvent, an immunoaffinity clean-up and HPLC with fluorescence detection. Whilst assays with naturally contaminated and with spiked samples of several herbs showed that the recoveries were somewhat low and dependent on the kind of sample and the degree of grinding, the intra-batch reproducibility was good, allowing a reliable quantitation by the standard-addition method.
