Nano-Ag Particles Embedded in C-Matrix: Preparation, Properties and Application in Cell Metabolism.

The application of nano-Ag grains as antiviral and antibacterial materials is widely known since ancient times. The problem is the toxicity of the bulk or big-size grain materials. It is known that nano-sized silver grains affect human and animal cells in some medical treatments.

[Effect of hemodialysis on left ventricular function in patients with chronic renal failure assessment with radionuclide ventriculography].

To examine the effects of haemodialysis (HD) on left ventricular (LV) function, gated radionuclide ventriculography was conducted before and after HD in 16 patients with chronic renal failure (CRF) and in 12 healthy persons. The LV sectorial function was assessed by subdividing the LV region of interest into 6 sectors. Global ejection fraction (EF) was unchanged by dialysis (61.
