Circumstantial evidence suggests that increased apoptosis is responsible for the loss of dopaminergic nigrostriatal neurons in Parkinson's disease (PD). It is impossible to perform high-quality studies on human postmortem material because of the low quality of tissue preservation, and the fact that apoptosis has a duration of only hours, and that the duration of the agonal period itself will le...

strongyloides stercoralis (ss) is a unique nematode with an auto infective cycle, so that it completes its life cycle within the human host and can live there for many years. in immunocompromised patients, infection can cause strongyloides hyperinfection syndrome (s.h.s) that is associated with serious morbidity and mortality. as vari-ous infections are one of the leading causes of membranoprol...

OBJECTIVES To investigate the question of whether there is an association between exposure to silica or respirable glass fibre and mortality from nephritis or nephrosis among workers in fibrous glass wool manufacturing facilities. METHODS A case-control study with cases and controls derived from the Owens Corning mortality surveillance system. Two case-control analyses were carried out, one w...

One approach to the study of wear involves the ch~~te~zation of surface failure under conditions of single-pass sliding. Such an approach has been used to show that the wear of commercial and experimental restorative resins and composites is determined by the resistance of the material to penetration and by the mode of deformation during sliding [l] . The purpose of this investigation was to ch...
