None of the enteric caliciviruses except Po/Sapo/GIII/Cowden/80/US replicates in cell culture, which complicates efforts to develop control strategies or to study viral replication. To develop serological assays for bovine noroviruses (BoNVs) and to determine the cross-reactivity of BoNV with human noroviruses, we generated two recombinant baculoviruses, rCV186-OH and rJNCV, to express the caps...

Abstract Tools to monitor SARS-CoV-2 transmission and immune responses are needed. We present a neutralization ELISA determine the levels of Ab-mediated virus preclinical model focused immunization strategy. The is strongly correlated with elaborate plaque reduction test (? = 0.9231, p < 0.0001). potency convalescent sera correlates IgG titers against receptor-binding domain (RBD) spike ...

Bertino, Ferrari and Atluri (BFA) have recently presented a model for specifying and enforcing authorization constraints for Workflow Management Systems (WFMS). The model is comprehensive and exhibits strong properties such as (1) a language to express constraints, (2) formal notions of constraint consistency and (3) algorithms for role-task and user-task assignments. In this paper, we extend t...

Recently, IACR ePrint archive posted two fully homomorphic encryption schemes without bootstrapping. In this note, we show that these schemes are trivially insecure. Furthermore, we also show that the encryption schemes of Liu and Wang [6] in CCS 2012 and the encryption scheme of Liu, Bertino, and Xun [5] in ASIACCS 2014 are insecure either.

We have used computer-assisted cytokine ELISA spot analysis to measure the frequencies, the type of cytokine, and the amount of cytokine produced by individual recall Ag-specific CD4 memory cells in freshly isolated blood. We studied the memory cells specific for tetanus toxoid and purified protein derivative in 18 healthy individuals and in 22 HIV-infected patients on highly active antiretrovi...

introduction: viral hepatitis is one of the causes of premature death in world peoples, according to who reports, five percentage of people are carrier, lethal from this disease is 1%, therefore about 1-1.5 million people each year die from complications of this disease. this disease varies from an acute to chronic illness. the aim of this study was to determine the level of anti-hbs ag (hepati...

background: tuberculosis (tb) remains an important health problem throughout the world. despite its significance in public health, mechanisms of protective immunity against mycobacyerium tuberculosis in humans have not yet been understood. objective: to evaluate cell mediated immune response against purified ag 85, ppd and phytohemagglutinin (pha) in patients with tuberculosis and healthy tuber...

several studies have demonstrated that herbal extracts possess various biological effects including anti-inflammatory and  anti-cancer  activities. the  present  study  was aimed to investigate the protective effects of the astragalus gypsicolus  (ag) hydroalcoholic extract in early allergic sensitized mice induced by ovalbumin. phytochemical assay was used  to  recognize the  main active const...

INTRODUCTION Ginger has a long history of medicinal use, particularly as an anti-inflammatory agent for a wide variety of diseases such as arthritis. Suppression of inflammation in arthritis is attributed to suppression of proinflammatory cytokines and chemokines produced by synoviocytes, chondrocytes, and leukocytes. OBJECTIVE This study aimed to elucidate the effect of a combination ginger ...
