Microglia belong to the mononuclear phagocyte system. They represent the brain resident tissue macrophages and function as the scavenger cells in brain. In Alzheimer's disease (AD), microglia become activated. Reactive microglia aggregate around senile plaque beta-amyloid and neurofibrillary tangles. Heavy accumulation of these pathological debris in postmortem, however, indicates the failure o...

cutaneous hodgkin’s lymphoma is a rare disease (0.5% to 3.4%) which tends to be in the setting of an advanced disease and has a poor prognosis. treatment of patients with cutaneous involvement of hodgkin’s lymphoma is according to dissemination of disease (systemic or localized therapy). the majority of data in this context are based on individual case reports or literature reviews. we have rep...

the main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. we were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. if such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. in addi...
