Molecular Characterization of Animal Strains of Hepatitis E Virus (HEV): Avian HEV and Swine HEV
Hepatitis E virus (HEV), the causative agent of hepatitis E, is an important public health concern in many developing countries. It mainly infects young adults and has a mortality of up to 25% in pregnant women. Although hepatitis E is only sporadic in industrialized countries including the United …

Performance studies of HEFSM with 6 slot- 7 pole for HEV application
… employed in hybrid electric vehicles (HEVs). Hybrid excitation flux switching machines (HEFSM) is one type of HEMs. This project is to decrease the PM size in a HEFSM so that the cost of the machine can be reduce. By reducing the size of PM, the torque and the power of the machine will …

Foodborne Transmission and Molecular Mechanism of Cross-species Infection of Hepatitis E Virus (HEV)
Hepatitis E virus (HEV), the causative agent of hepatitis E, is an emerging virus of global distribution. At least four distinct genotypes of HEV exist worldwide: genotype 1 and 2 HEV strains are responsible for waterborne epidemics; genotype 3 and 4 HEV strains are responsible for sporadic …

Finite element simulation based design and optimization of electric motors for EV/HEV traction application
The launch of so many commercial electric vehicles shows the effort toward pollution reduction and curtailing greenhouse gas emissions. A design for an electric vehicle does not just requires the electrical system to be efficient in particular; but it is required to perform in all extreme cases of …

Understanding the challenges in HEV 5-cycle fuel economy calculations based on dynamometer test data
EPA testing methods for calculation of fuel economy label ratings, which were revised beginning in 2008, use equations that weight the contributions of fuel consumption results from multiple dynamometer tests to synthesize city and highway estimates that reflect average U.S. driving patterns. The …

Real-Time Optimization Based Power Flow Controller for Energy Consumption and Emissions Reduction in a Parallel HEV
… become higher, Hybrid Electric Vehicles (HEV) are gaining more popularity in the market. HEVs improvements in fuel economy and emissions strongly depend on the energy management strategy. An optimization based power flow controller is presented in this thesis to find the appropriate power …

Cross-Species Infection and Characterization of Avian Hepatitis E Virus
As novel or variant strains of HEV continue to evolve rapidly both in humans and other animals, it is important to develop a rapid pre-sequencing screening method to select field isolates for further molecular characterization. Two heteroduplex mobility assays (HMA) were developed to genetically …

Cross-protection and Potential Animal Reservoir of the Hepatitis E Virus
HEV is an important public health concern due largely to water-borne outbreak. Recent research confirms individual cases of zoonotic transmission due to human exposure to contaminated animal meats. At least four recognized and two putative genotypes of mammalian HEV have been reported: genotypes 1 …

Evidence of Extrahepatic Sites of Replication of the Hepatitis E Virus in a Swine Model
Hepatitis E virus (HEV) is the major cause of enterically transmitted non-A, non-B hepatitis in many developing countries, and is also endemic in many industrialized countries. Due to the lack of an effective cell culture system and a practical animal model, the mechanisms of HEV pathogenesis and …

Pathogenesis and Cross-species Infection of Hepatitis E Virus
Hepatitis E Virus (HEV), the causative agent of hepatitis E, is a zoonotic pathogen of worldwide significance. The genus Orthohepevirus A of the family Hepeviridae includes all mammalian strains of HEV and consists of 8 recognized genotypes. Genotypes 1 and 2 HEVs only infect humans and genotypes 3 …

Molecular and Serological Epidemiology of Swine Hepatitis E Virus from Pigs in Two Countries
Hepatitis E virus (HEV), the causative agent of hepatitis E, is endemic in many developing countries. However, sporadic cases of acute hepatitis E have also been reported in industrialized countries including the United States. Increasing evidence suggested that hepatitis E is zoonotic. Swine HEV …

Understanding the Role of the Hypervariable Region in the Open Reading Frame 1 of the Hepatitis E virus in Viral Replication
Hepatitis E virus (HEV) is a major cause of enterically transmitted acute viral hepatitis in developing countries that lack proper hygienic infrastructure. Hepatitis E is globally distributed and has emerged as an important public health disease in both developing and industrialized countries. HEV …

Mechanism of Pathogenesis and Replication of an Avian Strain of the Hepatitis E Virus in a Chicken Model
… importance. The mechanism of pathogenesis of HEV is poorly understood due to the lack of an in vitro cell culture system and an ideal animal model system. With the discovery of avian HEV and its association with a hepatic disease (Hepatitis-Splenomegaly syndrome), chickens provide an excellent …

Discovery of Novel Strains of Animal Hepatitis E Viruses in the United States: Antigenic and Genetic Characterization, Cross-Species Infection, and Public Health Implications
Hepatitis E virus (HEV) is an important human pathogen, with pigs and likely other animal species serving as natural reservoirs. There are currently four recognized HEV genotypes that infect humans within the genus Hepevirus of the family Hepeviridae. Genotypes 1 and 2 are human viruses that are …

The use of transgenic tobacco as a production and delivery system for a vaccine against hemorrhagic enteritis virus of turkeys
Hemorrhagic enteritis virus (HEV) causes an acute viral disease in turkeys characterized by bloody diarrhea and death. Current live HEV virus vaccines are immunosuppressive and predispose turkeys to secondary bacterial infections. Data indicates that the capsid proteins (fiber, penton base, hexon) …

L'epatite E nei suidi: epidemiologia, diagnosi e filogenesi
… The aetiological agent is the Hepatitis E virus (HEV). The disease represents an important Public Health problem in developing countries where is frequently epidemic and primarily transmitted by fecal-oral route. In the last few years, a certain number of sporadic cases have been also described in …
