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 ...

The house cricket, Acheta domesticus, is a commonly reared insect for food and feed purposes. In 1977, report described colony collapse, which was caused by the single-stranded DNA virus domesticus densovirus (AdDV). Currently, there are no confirmed A. colonies free of AdDV, viral disease outbreaks continuous threat to mass rearing. Correlations between cricket rearing density or temperature A...

Viral pathogens utilize various human organs for infection, and the gut is one of primary entry sites viral pathogen. The epithelium tightly maintained since multiple harmful substances, including pathogens, attack it. outbreak new viruses or strains often poses a massive threat to life, so we need understand how they develop prevent them by inventing therapeutic approaches, drugs vaccines. The...

Abstract As the coronavirus disease 2019 (COVID-19) pandemic continues to be a multidimensional threat humanity, more evidence of neurological involvement associated with it has emerged. Neuroimmune interaction may prove important not only in pathogenesis manifestations but also prevent systemic hyperinflammation. In this review, we summarize reports COVID-19 cases involvement, followed by disc...

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 ...

PURPOSE OF REVIEW Recently, several previously unrecognized respiratory viral pathogens have been identified and several influenza A virus subtypes, previously known to infect poultry and wild birds, were transmitted to humans. Here we review the recent literature on these respiratory viruses. RECENT FINDINGS Human metapneumovirus has now been detected worldwide, causing severe respiratory tr...

This paper aims to model the cause-and-effect relationships between world economy’s digital development and sustainable living. A broad selection of developed developing countries examines what economy would have looked like without crisis in 2020. Drawing on whether virus is swept off or merely reduced, dataset contains a forecast for 2022. Being aware alternative scenarios can be helpful wide...

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...
