Sediment characteristics and microbiological contamination of beach sand - A case-study in the archipelago of Madeira.

Beach sand can harbour pathogenic and opportunistic microorganisms, as well as faecal indicator bacteria that influence directly the bathing water quality. Pathogenic and opportunistic microorganisms often raise concern of exposure during beach related recreational activities. In this work, three different types of sandy beaches (natural basaltic, natural calcareous and artificial calcareous) of the Archipelago of Madeira (Portugal) were sampled for bacterial and fungal contaminants and grain size distribution, during four years (2010-2013).

Analysis of Aspergillus nidulans germination, initial growth and carbon source response by flow cytometry.

In this work, flow cytometry was utilized to analyze the initial vegetative growth of the model fungus Aspergillus nidulans as measured by the number of events increasing size and internal complexity. It was established the ideal parameters for the analysis of conidial populations, whose growth was followed after germination in glucose or sucrose. While glucose in culture increased growth several magnitudes in comparison to control cultures in saline, growth was less intense in cultures amended with sucrose.

Herlyn-Werner-Wunderlich syndrome: a rare cause of pelvic pain in adolescent girls.

The Herlyn-Werner-Wunderlich syndrome is a rare congenital anomaly characterised by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. It usually presents after menarche with progressive pelvic pain during menses secondary to haematocolpos. Awareness is necessary in order to diagnose and treat this disorder properly before complications occur.
