Abstract Adhesion of bacteria and platelets on blood-contact implants surgical devices is one the causes infections thrombus. A superhydrophobic surface serving as a protective layer can minimize adhesion contamination due to low energy. The objective this paper construct titanium implant by combination topological structure chemical coating. First, micro/nano hierarchical morphology obtained s...

Abstract Objectives The article presents the results of an in vitro study aimed at identifying changes parameters oxidative stress – concentration malondialdehyde (MDA), enzymatic activity superoxide dismutase (SOD-1) and protective antioxidant role melatonin (MLT) during exposure blood platelets to electromagnetic radiation (EMR) emitted by monitors. Methods Platelets were exposed EMR for 30- ...

Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...

ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. the importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. up to now, different materials such as z...

PURPOSE Rapid development of nanotechnology has recently brought significant attention to the extraordinary biological features of nanomaterials. The objective of the present investigation was to evaluate morphological characteristics of the assembles of gold and platinum nanoparticles (nano-Au and nano-Pt respectively), with Salmonella Enteritidis (Gram-negative) and Listeria monocytogenes (Gr...

Environmental, health, and safety (EHS) concerns are receiving considerable attention in nanoscience and nanotechnology (nano) research and development (R&D). Policymakers and others have urged that research on nano's EHS implications be developed alongside scientific research in the nano domain rather than subsequent to applications. This concurrent perspective suggests the importance of early...
