The present study was carried out to investigate the protective effect of Physalis peruviana L. (family Solanaceae) against cadmium-induced neurotoxicity in rats. Adult male Wistar rats were randomly divided into four groups. Group 1 was used as control. Group 2 was intraperitoneally injected with 6.5 mg/kg bwt of cadmium chloride for 5 days. Group 3 was(More)
S ince the discovery of the hepatitis C virus (HCV) in the late 1980s, there has been an explosion of information regarding its natural history, treatment, and replication cycle. Nonetheless, there are still relatively few data regarding acute HCV infection. By convention, the term acute hepatitis refers to the presence of clinical signs or symptoms of(More)
Given the failures of nonreplicating vaccines against chronic hepatitis C virus (HCV) infection, we hypothesized that a replicating viral vector may provide protective immunity. Four chimpanzees were immunized transdermally twice with recombinant vaccinia viruses (rVV) expressing HCV genes. After challenge with 24 50% chimpanzee infective doses of(More)
OBJECTIVE To investigate the association between hepatitis C virus (HCV)-specific cell-mediated immunity (CMI) responses and viral clearance in children born to mothers infected with HCV. STUDY DESIGN A cross-sectional study of children from a mother-infant cohort in Egypt were enrolled to detect CMI responses to recombinant core and nonstructural HCV(More)
There are only limited data on whether HIV infection occurs within the liver; therefore, we explored early and late stages of the HIV life cycle in two hepatocyte cell lines – Huh7.5 and Huh7.5JFH1 – as well as in primary human hepatocytes. Integrated HIV DNA was detected in Huh7.5 and Huh7.5JFH1 cells, as well as in primary hepatocytes, and was inhibited(More)
To facilitate invasion, reovirus has evolved to attach to M cells, a specialized epithelium residing within the follicle-associated epithelium that covers mucosal inductive tissues. Thus, we questioned adapting reovirus protein sigma1 to ferry DNA vaccines to the mucosa to immunize against HIV. Three expression plasmids encoding HIV(Ba-L) gp160, cytoplasmic(More)
In the United States, the seroprevalence rate for hepatitis E virus (HEV) is approximately 20%. This study examined HEV seroprevalence in persons with and without chronic liver disease. Our data indicate that HEV seropositivity is high in patients with chronic liver disease and that HEV seroprevalence increases significantly with age.
OBJECTIVE Cape gooseberry (Physalis peruviana L.) belongs to the Solanaceae family. Physalis has many medicinal properties however, the beneficial effect of physalis in protecting against neurotoxins has not yet been evaluated. This experimental study investigated the protective effect of physalis juice against the oxidative damage induced by carbon(More)
The IL28B gene is associated with spontaneous or treatment-induced HCV viral clearance. However, the mechanism by which the IL28B single nucleotide polymorphism (SNP) affects the extra-hepatic HCV immune responses and its relationship to HCV pathogenesis have not been thoroughly investigated. To examine the mechanism by which IL28B affects HCV clearance.(More)
