We have studied the number of endothelial precursor cells in eighteen patients undergoing allogeneic haematopoietic stem cell transplantation. Endothelial precursor cells were evaluated by colony-forming assay and compared to healthy controls. Patients undergoing allogeneic haematopoietic stem cell transplantation had significantly lower numbers of endothelial precursor cells before the procedu...

OBJECTIVE Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), likely prevent cardiovascular disease, however their mechanisms remain unclear. Recently, the role of DNA damage in atherogenesis has been receiving considerable attention. Here, we investigated the effects of EPA and DHA on DNA damage in vascular endothelial cells to clarify their antiathero...

Morphological changes of microvessels of cerebral cortex were evaluated in a model of cerebral infarction initiated by a photochemical reaction. Rats were treated with intravenous injection of rose Bengal and irradiated from a halogen lamp source through an intact cranium to precipitate microvascular damage. Investigations in transmission and scanning electron microscopy revealed platelet aggre...

Monocytes have been shown to infiltrate in brain tissue during various neurological disorders including AIDS dementia complex. The presence of an excess of activated macrophages in brain tissue is accompanied by tissue damage resulting in a loss in neuronal function and viability. Therapeutic options against such neurological disorders could therefore be aimed at the prevention of monocyte infi...

Hemotrophic mycoplasmas (HM) are highly specialized red blood cell parasites that cause infectious anemia in a variety of mammals, including humans. To date, no in vitro cultivation systems for HM have been available, resulting in relatively little information about the pathogenesis of HM infection. In pigs, Mycoplasma suis-induced infectious anemia is associated with hemorrhagic diathesis, and...

We read with interest the report by Malik et al. [1] that suggested that a continuum probably exists between endoboth atorvastatin and fenofibrate equally improved endothelial activation (from early exposure to risk factors, such thelium-dependent arterial vasoreactivity in patients with as smoking), endothelial dysfunction (resulting in thromcombined hyperlipidaemia. Interestingly, a recent st...

Human cytomegalovirus (CMV) infection has been linked to inflammatory diseases that involve vascular endothelial damage, including vascular disease and chronic transplant rejection. We previously reported that the host CD4(+) T-cell response to CMV antigen presented by endothelial cells can produce interferon-gamma and tumor necrosis factor-alpha at levels sufficient to drive induction of fract...

Acute pancreatitis is an inflammatory condition marked by localized tissue damage that may lead to a broader reaction. There growing evidence patients with severe form of acute have endothelial dysfunction as one the key pathophysiologic symptoms. In line this, there been new studies linking hematological thrombotic thrombocytopenic purpura (TTP).Here, we are describing rare conversive event in...

Pathogenic Leptospira transmits from animals to humans, causing the zoonotic life-threatening infection called leptospirosis. This infection is reported worldwide with higher risk in tropical regions. Symptoms of leptospirosis range from mild illness to severe illness such as liver damage, kidney failure, respiratory distress, meningitis, and fatal hemorrhagic disease. Invasive species of Lepto...
