Blood microrheology depends on the constituents of blood plasma, the interaction between blood cells resulting in red blood cell (RBC) and platelets aggregation, and adhesion of RBC, platelets and leukocytes to vascular endothelium. The main plasma protein molecule -actuator of RBC aggregation is fibrinogen. In this paper the effect of interaction between the endothelium and RBC at different fibrinogen concentrations on the RBC microrheological properties was investigated in vitro.

Dysregulation of this process underlies the pathogenesis of diseases such as atherosclerosis, obesity, diabetes, and cancer. However, to date, only some mechanisms of lipid endocytosis have been discovered.

In this study, novel amphiphilic 5,10,15,20-tetrakis(4-(3-pyridyl--propanoyl)oxyphenyl)porphyrin tetrabromide (), 5,10,15,20-tetrakis(4-(6-pyridyl--hexanoyl)oxyphenyl)porphyrin tetrabromide () and known 5,10,15,20-tetrakis(1-methyl-4-pyridinio)porphyrin tetraiodide () were synthesized, and their dark antiviral activity in vitro against HSV-1 was studied. The influence of porphyrin's nanosized delivery vehicles based on Pluronic F127 on anti-HSV-1 activity was estimated.

The InlB protein produced by the Gram-positive bacterium Listeria monocytogenes is an agonist of the tyrosine kinase receptor c-Met and a functional analog of the hepatocyte growth factor (HGF), which is a mammalian ligand of c-Met. The recombinant InlB protein, which is the c-Met-binding InlB domain (amino acids 31-321), was cloned from the L.

It was found that production of anti-inflammatory cytokines IL-1β, IL.6, and TNF-α in infected cultures depended on the level of their spontaneous production, while IL-8 production was suppressed irrespective of its spontaneous level.
