background and objective: the circle of willis (cow) supports adequate blood supply to the brain. the cardiovascular system, in the current study, is modeled using an equivalent electronic system focusing on the cow. method: in our previous study we used 42 compartments to model whole car- diovascular system. in the current study, nevertheless, we extended our model by using 63 compartments to ...

thalamic pain syndrome, a type of central post-stroke pain (cpsp), may develops after a hemorrhagic or ischemic stroke and results in impairment of the thalamus. there is limited experience about gabapentin in treatment of central pains like cpsp.in a prospective observational study, the intensity of pain was recorded using the numeric rating scale (nrs) at the entrance to the study. patients e...

BACKGROUND AND OBJECTIVE: Primary angiitis of the central nervous system (PACNS) is an inflammatory vasculitis with very low frequency and prevalence. It is not clear why the inflammatory process of this disease is limited to cerebrovascular disease without systemic manifestations. A case of primary angiitis of the central nervous system with cerebrovascular manifestations is reported here.  C...

background chlamydia pneumoniae has been linked with increased risk of cardiovascular diseases; however, data on stroke and cerebrovascular accidents are sparse. objectives the aim of this study was to determine the association between c. pneumoniae infection and ischemic stroke. patients and methods in a case-control study, 141 patients, admitted with ischemic stroke, were compared with gender...
