The virion host shutoff (vhs) protein of herpes simplex virus type 1 causes the degradation of host and viral mRNA immediately upon infection of permissive cells. vhs can interact with VP16 through a 20-amino-acid binding domain, and viruses containing a deletion of this VP16-binding domain of vhs (Delta20) and a corresponding marker rescue (Delta20R) were constructed and characterized. Transie...

Herpes simplex virus (HSV) virions contain one or more factors that trigger rapid shutoff of host protein synthesis and accelerated decay of cellular and viral mRNAs in infected cells. HSV isolates bearing mutations at the virion host shutoff (vhs) locus (gene UL41) are defective for both processes, indicating that the vhs protein is required; however, it is not clear whether the role of vhs in...

BACKGROUND Complex visual hallucinations (VHs) occur in several pathologic conditions; however, the neural mechanisms underlying these symptoms remain unclear. Although dopamine may have a role, indirect evidence indicates that serotonin may also contribute to the pathogenesis of complex VHs, probably via involvement of the serotonin 2 receptor. OBJECTIVE To examine for the first time in vivo...

Much of the research on visual hallucinations (VHs) has been conducted in the context of eye disease and neurodegenerative conditions, but little is known about these phenomena in psychiatric and nonclinical populations. The purpose of this article is to bring together current knowledge regarding VHs in the psychosis phenotype and contrast this data with the literature drawn from neurodegenerat...

One of the most valuable aquaculture fish in Europe is the rainbow trout, Oncorhynchus mykiss, but the profitability of trout production is threatened by a highly lethal infectious disease, viral hemorrhagic septicemia (VHS), caused by the VHS virus (VHSV). For the past few decades, the subgenogroup Ia of VHSV has been the main cause of VHS outbreaks in European freshwater-farmed rainbow trout....

Mice lacking the Stat1 interferon signaling gene were infected with herpes simplex virus type 1 (HSV-1) or an attenuated recombinant lacking virion host shutoff (Delta vhs). Delta vhs virus-infected Stat1(-/-) mice showed levels of replication equivalent to that of the wild-type virus-infected control mice but reduced relative to wild-type virus-infected Stat1(-/-) mice. Stat1 deficiency reliev...

A number of viral haemorrhagic septicaemia (VHS) virus isolates of European marine origin were shown to be of low pathogenicity or non-pathogenic to Atlantic salmon parr by water-borne infection. A reference freshwater VHS virus isolate known to be highly pathogenic to rainbow trout was also of low pathogenicity to Atlantic salmon. Virus was detected in some mortalities, however, demonstrating ...

BACKGROUND Treatment of irritable bowel syndrome (IBS) with probiotics has achieved effectiveness to a certain extent. Whether prebiotics will work is still unclear. This study aimed to investigate the therapeutic effects of the prebiotic isomalto-oligosaccharides (IMO) on visceral hypersensitivity (VHS) in rats and to explore potential mechanism. METHODS Water avoidance stress (WAS) was used...

VHS domains are found at the N-termini of select proteins involved in intracellular membrane trafficking. We have determined the crystal structure of the VHS domain of the human Tom1 (target of myb 1) protein to 1.5 A resolution. The domain consists of eight helices arranged in a superhelix. The surface of the domain has two main features: (1) a basic patch on one side due to several conserved ...

Objective: This study aimed to evaluate the vaccine hesitancy, anti-vaccination, and anxiety levels of medical secretaries during pandemic.
 Methods: cross-sectional was conducted on 161 working at time Study. Sociodemographic characteristics form, Coronavirus Anxiety Scale (CAS), Vaccine Hesitancy (VHS) adapted pandemic, Anti-vaccination (AVS) were used in questionnaire form collect data ...
