The objective of this paper is to describe the development of an educational purpose computerbased simulator for Hybrid Electric Vehicle (HEV) technology. The tremendous capital investment, tedious and time-consuming tasks required to establish a full function of HEV laboratory are convincing evidence that the HEV curriculum is in need of a low-cost, computerbased virtual HEV simulator. An inte...
Human enteroviruses are currently grouped into five species Human enterovirus A (HEV-A), HEV-B, HEV-C, HEV-D and Poliovirus. During surveillance for enteroviruses serologically non-typable enterovirus strains were found from acute flaccid paralysis patients and healthy individuals. In this study, we report isolates of recently described enterovirus types EV76 and EV90 of HEV-A species and chara...
Hepatitis E virus (HEV) seroprevalences of 0.3%-53% were reported from industrialized countries. Because these estimates may be influenced by detection assays, this study compares 3 frequently used tests for HEV detection: the MP Diagnostics HEV immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA), the Axiom Diagnostics HEV IgG enzyme immunoassay (EIA), and the Mikrogen recomLine HE...
The interplay between host antiviral immunity and immunopathology during hepatitis E virus (HEV) infection determines important clinical outcomes. We characterized the specificity, functionality, and durability of host T-cell responses against the full-length HEV virus and assessed a novel "Quantiferon" assay for the rapid diagnosis of HEV infection. Eighty-nine volunteers were recruited from O...
Hepatitis E virus (HEV) is one of the main causes viral hepatitis infection worldwide. Sources contamination can vary greatly according to geographical regions and HEV genotypes. endemic responsible for large waterborne epidemics involving human HEV-1 or HEV-2 genotypes in with limited sanitation, contrast industrialized countries, where mainly a foodborne zoonosis HEV-3 HEV-4 zoonotic Limited ...
Hepatitis E virus (HEV) infection has a worldwide distribution and represents an important cause of acute hepatitis. This study aims to investigate the occurrence of HEV infection and factors associated with this infection in patients with acute non-A, non-B, non-C hepatitis in Central Brazil. From April 2012 to October 2014, a cross-sectional study was conducted among 379 patients with acute n...
BACKGROUND Although so far several studies have determined the hepatitis E virus (HEV) prevalence in some parts of Iran, no data exists regarding the HEV seroprevalence in Bushehr province as the southernmost point in Iran yet. OBJECTIVES The aim of this study was to evaluate the seroprevalence of anti-HEV IgG among the blood donors in Bushehr. PATIENTS AND METHODS A total of 628 blood dono...
Human enterovirus (HEV) infections can be asymptomatic or cause only mild illness; recent evidence may implicate HEV infection in type 1 diabetes mellitus and myocarditis. Here, we report the molecular characterization of HEV obtained in serial monthly collections from healthy Norwegian infants. A total of 1,255 fecal samples were collected from 113 healthy infants beginning at age 3 months and...
Hepatitis E virus (HEV) genotypes 3 and 4 are zoonotic pathogens, with pigs predominantly implicated in disease transmission. The rapid rise in human cases in developed countries over the past decade indicates a change in epidemiology of HEV, and it has been suggested that additional animal species may be involved in transmission of infection. Multiple studies have identified contact with dogs ...
Background. Knowledge regarding prevalence of HEV in general population can be an indicator of the public health and hygiene. Therefore, this study was conducted to evaluate the prevalence of HEV among adults in South-West of Iran. Methods. Blood samples were taken from 510 participants, 206 (40.4%) males and 304 (59.6%) females from February to July 2014. Detection of anti-HEV IgG and IgM anti...
