The clinical significance of the interaction antibodies with circulating platelets is well documented, but mechanisms underlying these interactions are not fully known. Here we describe characterization anti-human platelet membrane protein monoclonal antibody (mAb) termed F11. Interaction mAb F11 human resulted in dose-dependent granular secretion, measured by [14C]serotonin and ATP release, fibrinogen binding aggregation. Analysis specific to revealed a high affinity site 8,067 +/- 1,307...

ABSTRACT In this article, the properties of thermosensitive chitosan hydrogels (structural and biological) prepared using chloride β‐glycerophosphate are presented. The porous structure gels was observed with a scanning electron microscopy (SEM). Rheological other structural morphological investigations were carried out by infrared spectroscopy X‐ray photoelectron spectroscopy. Crystallinity gel determined diffraction analysis. Biocompatibility investigated contact bone cells (line Saos‐2)...

Titanium alloys are still on the top list of fundamental materials intended for dental, orthopedics, neurological, and cardiovascular implantations. Recently, a special attention has been paid to vanadium-free titanium alloy, Ti6Al7Nb, that seems represent higher biocompatibility than traditional Ti6Al4V alloy. Surprisingly, these data not thoroughly elaborated in literature; particularly there is lack comparative experiments conducted simultaneously at same conditions. Our study fills...

The aim of the present study was to relate impairments in calcium mobilization and/or release altered membrane dynamics platelets from patients with type 2 diabetes mellitus. Higher expression P-selectin (1.4-fold, NS) and reduction GPIb alpha (by 27.8+/-16.7%, p < 0.0002), as well increased fractions platelet microparticles (p 0.03), reflected more intensified reaction diabetic platelets. Overall, appeared vulnerable stimuli facilitating 41%, 0.01) less susceptible preventive effects agents...

Nematode Caenorhabditis elegans (C. elegans) was used to investigate the impact of silver nanoparticles (SNP), multiwalled carbon nanotubes (MWCNT), and polyamidoamine dendrimers (PAMAM) in concentration 1010 particle/mL. Population-based observations gene expression analysis were employed this study. SNP PAMAM caused decrease number live nematodes their body length, but MWCNT did not affect population nematodes. Gene revealed significant changes by presence all studied nanomaterials,...

A new variant of viral haemorrhagic disease rabbits (VHD) virus, recently detected in Poland and called Blaszki (BLA), gives positive results enzyme-linked immunosorbent assay (ELISA) exhibits protein 60 kilodaltons (VP 60), as by Western blot analysis. This BLA VHD virus has caused high morbidity mortality rabbits, have other reported variants with similar clinical signs pathological lesions, but-in contrast to variants-the gave negative the haemagglutination test. development indicates...

This work studied the susceptibility of biofilm produced by E. coli to oxidative stress, and compared components free radicals defences: level glutathione, catalase dismutase activities in planktonic located cells. Results showed diversity responses stress bacterial cells log or stationary phases both forms. The bacteria were exposed free-radical donors (H2O2, tBOOH, menadione, SIN-1 peroxynitrite) a wide range final concentrations, from 0.5 10mM. Different toxicity individual donors,...

The mean platelet volume, measured optically and by the electrical impedance method, was analysed in patients with chronic renal failure. All parameters describing circulating biomass except volume heterogeneity were decreased these patients. There is a strong inverse relation between Ivy bleeding time mass patient group. Our results indicate that smaller platelets failure may contribute to uremic diathesis, disturbed thrombocytopoiesis occurs

Endothelial cell aging is related to changes not only in phenotype, such as luminal changes, intimal and medial thickening, increased vascular stiffness, but encompasses different responses various substances including drugs or nanomaterials. In the present work, time- dose-dependent elasticity evoked by silver nanoparticles endothelial cells early (below 15) passages were analyzed. Silver nanoparticle concentrations of 3, 3.6, 16 μg/mL selected for measurements long incubation (24 hours) 1...
