Laser-synthesized oxide-passivated bright Si quantum dots for bioimaging.

Crystalline silicon (Si) nanoparticles present an extremely promising object for bioimaging based on photoluminescence (PL) in the visible and near-infrared spectral regions, but their efficient PL emission in aqueous suspension is typically observed after wet chemistry procedures leading to residual toxicity issues. Here, we introduce ultrapure laser-synthesized Si-based quantum dots (QDs), which are water-dispersible and exhibit bright exciton PL in the window of relative tissue transparency near 800 nm. Based on the laser ablation of crystalline Si targets in gaseous helium, followed by ultrasound-assisted dispersion of the deposited films in physiological saline, the proposed method avoids any toxic by-products during the synthesis.

Glycaemic Control and Associated Self-Management Behaviours in Diabetic Outpatients: A Hospital Based Observation Study in Lusaka, Zambia.

Background: The control of diabetes mellitus depends on several factors that also include individual lifestyles. We assessed glycaemic control status and self-management behaviours that may influence glycaemic control among diabetic outpatients.

Methods: This cross-sectional study among 198 consenting randomly selected patients was conducted at the University Teaching Hospital diabetic clinic between September and December 2013 in Lusaka, Zambia.

Glycaemic control in diabetic patients in Zambia.

Introduction: The glycaemic control status of diabetic patients affects the management of their disorder. We examined the glycaemic control and clinical factors that may influence the achievement of the glycaemic control targets among diabetic out-patients.

Methods: This was a hospital based cross-sectional study carried out at the University Teaching Hospital diabetic clinic in Lusaka, Zambia.

Telemedicine in practice in Arkhangelsk region, Russia: from a blank page to routine operation.

Objectives: This article describes the telemedical activities in the Arkhangelsk region of north-west Russia from 1996 to 2004, and some of the outcomes of introducing telemedicine in health care.

Study Design: The study acquired statistical data between 1996 and 2004 from the telemedical network in the Arkhangelsk region. The network was intended to be low cost and to function using existing communication systems.

[Correction of lipid peroxidation disorders in experimental traumatic shock using the antioxidant ionol].

The level of certain parameters of lipid peroxidation and the activity of lysosome hydrolases were studied on the shock model in rats. It was established that the traumatic shock in the experiment is accompanied by the growth of the level of over-oxidation products (malonic dialdehyde, diene conjugates), the rate of erythrocyte hemolysis as well as by an increase in the hydrolase activity. Administration of ionol (60 mg/kg) inhibits the higher activity of radical-free lipid oxidation, decreases the damage of membrane structure and the metabolism disturbance.
