Reduced rank regression dietary patterns and dyslipidemia in Brazilian adolescents: results from the Study of Cardiovascular Risk in Adolescents (ERICA).

Background: Evidence on the harmful effects of diet on serum lipids in adolescence has not been consistent. The present study sought to establish which dietary patterns are associated with biomarkers of dyslipidemia.

Methods: Data from 36,217 Brazilian adolescents participating in the Study of Cardiovascular Risk in Adolescents were evaluated.

Effects of acetazolamide on sleep disordered breathing in pulmonary vascular disease: a randomised controlled trial.

Background: Patients with pulmonary vascular disease (PVD) often suffer from nocturnal hypoxaemia, but also from sleep apnoea. Short-term use of acetazolamide increases ventilation due to metabolic acidosis and also reduces loop gain. We investigated whether prolonged use of acetazolamide improves sleep disordered breathing in PVD.

Heart rate variability in pulmonary vascular disease at altitude: a randomised trial.

Background: Hypoxia is a trigger for sympathetic activation and autonomic cardiovascular dysfunction. Pulmonary vascular disease (PVD) is associated with hypoxaemia, which increases with altitude. The aim was to investigate how exposure of patients with PVD to hypobaric hypoxia at altitude affects autonomic cardiovascular regulation.

Microbial Fabrication of Quantum Dots: Mechanism and Applications.

More recently, the application of semiconductor nanomaterials called quantum dots (QDs), has gained considerable attention as they possess tunable optoelectronic and physicochemical properties. There are several routes of QDs synthesis some of which include lithography, molecular beam epitaxy, and chemical reduction. However, most of these methods are expensive, labour intensive, and produce toxic by-products.
