conclusions therefore the non-infectious dlps were became infectious if introduced into the cytoplasm of permissive and cancerous cells, without passing attachment and entry process. results we attempt to avoid the attachment and entry of the rotavirus by using lipofectamine to mediate the delivery of viral particles directly into the cytoplasm. dlp was endocytosed into the cytoplasm following ...

conclusions there are few studies on the prevalence of viral hepatitis in the general population of iran. most of the reports are from specific groups of patients. further epidemiologic studies on the general population of iran are recommended to discover the real burden of viral hepatitis. context viral hepatitis is still considered as a major health concern. defining the extent of the burden ...

the population response of heliothis armigera larvae to nuclear polyhedrosis virus (npv) was investigated. the virus was introduced by permitting the larvae to feed on lettuce leaves. median lethal doses (ld50) were determined. the estimated ld50 values for the first, second, third, early, and late fourth larval instars were 5, 141, 1226, 5168 and 24553 polyhedra per larva respectively. in ...

introduction:blood-borne infectious agents are one of the main anxieties of blood transfusion organization in all countries. according to who, the blood healthy and blood safety is included ensuring and monitoring of quality and efficiency for all patients requiring blood transfusion. we at the current study intend that survey prevalence hiv ab, hcv ab, hbs ag among blood donors refer to the bl...

viral hepatitis is one of five infectional factors cause early death in all over the world. every day at least one million people die because of viral hepatitis. six hepatitis viruses have been known until now. they are a, b, c, d, e, g, and it is probable that at least two other kinds i.e. f, and h, will be known soon. only hepatitis b is a dna virus, and the others are rna viruses. all viruse...

800x600 background : hepatitis b and c infections have remained major global health burdens during the most recent century. the viral agents responsible for these diseases share common modes of transmission with human immunodeficiency virus (hiv) such as needle-sharing in iv drug abusers. coinfection of hepatitis b or c with hiv increases the rate of progression of chronic liver disease. given ...

reye's syndrome is defined as fatty liver degeneration and acute encephalopathy following diffused abnormal mitochondrial activity. we reported a two year old girl admitted with lethargy and meningismus despite no evidence of blood sugar decrease, history of previous viral disease or drug use, complete tests showed reye syndrome as the final diagnosis. conservative protocols and treatment inclu...

elevated serum level of bilirubin is a common manifestation which is occurred in several diseases. hyperbilirubinemia can manifest either conjugated or unconjugated. conjugated or direct hyperbilirubinemia usually are caused by hepatocellular diseases or cholestatic liver diseases. merely conjugated hyperbilirubinemia is the main manifestation of two congenital syndromes, including dubin-johnso...

background: hepatitis activity index (hai) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis b. the aim of this study was to determine the hai and fibrosing stage in patients with anti-hbe positive chronic hepatitis b. methods: liver biopsy slides of 72 patients were evaluated at the department of pathology in two teaching h...

conclusions it is concluded that most hbeag negative hepatitis b patients with serum hbv dna level of 2000-20000 iu/ml, persistent normal alt concentration, and no or mild liver damage on biopsy can be clinically managed as hbv inactive carriers. results two hundred forty-three hbeag negative hepatitis b patients were stratified into three groups based on to their hbv dna level including group ...
