C57BL/6 (B6) mice are genetically highly susceptible to chronic type II Toxoplasma gondii infections that invariably cause lethal toxoplasmic encephalitis. We examined the ability of an attenuated type I vaccine strain to elicit long-term immunity to lethal acute or chronic type II infections in susceptible B6 mice. Mice immunized with the type I cps1-1 vaccine strain were not susceptible to a ...

Recent FCC regulations have caused wireless operators to introduce new technologies into their networks for E911 compliance. This paper focuses on what these new regulations mean to wireless operators, LCC International’s position on testing and compliance, and the cost benefit of various testing methodologies.

BACKGROUND Toxoplasma gondii is an obligate intracellular parasite that infects humans at high prevalence rates. The virulent RH strain of T. gondii is generally considered to have lost its cyst forming capacity. This study performed to obtain tissue cysts in mice infected with tachyzoites of RH strain treated with sulfadiazine (SDZ). It provides the opportunity to analyze the conversion of tac...

BACKGROUND Presentation of magnetic resonance imaging (MRI) findings in pregnant women in the Department of Diagnostic Imaging, Institute of Mother and Child, Warsaw, Poland. MATERIAL/METHODS Forty-three symptomatic pregnant women underwent MRI between 9 and 33 weeks of gestation (mean of 23 weeks). Moreover, we included 2 pregnant women who underwent fetal MRI and had incidental abnormalitie...

OBJECTIVES To report the spectrum of brain magnetic resonance imaging findings in 13 patients with congenital muscular dystrophy and FKRP gene mutations and to explore possible genotype-phenotype correlations. DESIGN We retrospectively reviewed brain magnetic resonance imaging in patients with congenital muscular dystrophy and FKRP gene mutations. PATIENTS Thirteen patients with congenital ...

Intraoperative sonography using portable real-time equipment at the dural or brain surface in 16 patients provided accurate localization of a variety of brain lesions for direct dissectional or needle aspiration biopsies as well as for decompression of cysts. The technique has proven to be reliable and rapid, reducing brain exploration in the search for small or poorly accessible lesions and el...

(1) Background: Infection with Echinococcus granulosus is the cause of hydatid cysts located frequently in liver and lungs, but also kidneys, bones, spleen, brain muscles. Cystic echinococcosis sometimes complicated to treat, requiring radical surgery prolonged medication. The cyst retroperitoneal space asymptomatic, unless it grows produces symptoms caused by high intracystic pressure, seconda...

Cerebral parasitic cysts constitute a major problem for livestock. Among these, coenurosis and toxoplasmosis are predominant. Here, a total number of 60 sheep obtained from a private farm in Suez province, Egypt, were examined postmortem to detect visible parasitic cysts, and microscopically to detect small-sized entities. Necropsy revealed bladder-like cysts measuring 0.5-6.5 cm in diameter th...
