Acute and chronic Toxoplasma infections were evaluated in mice using stage specific antibodies and immunocytochemistry. Mice with acute toxoplasmosis were less active, had erectile body hair and seldom took food or water resulting in weight loss. All mice died within 7 days post-inoculation. The immunohistochemical technique enhanced visualization of parasites allowing their distribution to be ...

In immunocompromised hosts, latent infection with Toxoplasma gondii can reactivate from tissue cysts, leading to encephalitis. A characteristic of T. gondii bradyzoites in tissue cysts is the presence of amylopectin granules. The regulatory mechanisms and role of amylopectin accumulation in this organism are not fully understood. The T. gondii genome encodes a putative glycogen phosphorylase (T...

The use of quantitative mapping diffusion characteristics carries great potential for diagnosis and therapy brain diseases, since it potentially allows to classify tumors, determine the degree their malignancy, differentiate various morphological structures tumor non-tumor pathologies (such as stroma, necrotic zones, cysts, types edema, etc.), predict course outcome in particular, a clinical re...

A septum pellucidum cyst is defined as a fluid collection between the lateral ventricles whose walls have curvature and are separated by 10 mm or more . Most of these cysts benign their clinical significance should be considered neurodevelopmental anomaly that may contribute to neuropsychiatric abnormalities It often incidental finding, little significance. However, an association this developm...

background toxoplasmosis is a parasitic disease caused by the protozoan toxoplasma gondii. this parasite infects most of warm-blooded animals, including birds. turkeys are one of these animals which might be infected by this parasite. little is known about the prevalence of t. gondii in turkeys in iran. objectives the current study aimed to evaluate the rate of toxoplasma infection in turkeys i...

BACKGROUND The onset of anthelmintic treatment of neurocysticercosis (NCC) provokes an acute immune response of the host, which in human cases is associated with exacerbation of neurological symptoms. This inflammation can occur at the first days of therapy. So, changes in the brain cysts appearance may be detected by medical imaging. We evaluated radiological changes in the appearance of brain...

Background: Midline deeply seated brain cysts carry great risk during its surgery especially when they are recurrent and extend vertically via the third ventricle to the floor of lateral ventricle. Objectives: To evaluate the effect of Ommaya Reservoir in controlling recurrent cystic midline pathologies and improve their functional outcome. Patients and Methods: This prospective study was condu...

background: splenic cysts are rare in all age groups and there are a few reports in the world literature. primary cysts occur most frequently in children and young adults, comprising around 25% of all nonparasitic splenic cysts. various techniques are suggested for the treatment of splenic cysts. in this case report, a huge epithelial splenic cyst in a 17-year-old female is presented and differ...
