BACKGROUND/AIMS This study aimed to predict sustained viral response (SVR) to low-dose pegylated interferon (PEG-IFN) plus ribavirin of elderly and/or cirrhotic patients with genotype 2 hepatitis C virus (HCV) using viral response within 2 weeks. METHODS Low-dose PEG-IFN-α-2b plus ribavirin was administered to 50 elderly and/or cirrhotic patients with genotype 2 HCV for 24 weeks. The dynamics...

The effect of ganciclovir [9-(1,3-dihydroxy-2-propoxymethyl)guanine] on herpes simplex virus type 1 DNA and protein synthesis was studied. Ganciclovir markedly inhibited the synthesis of viral DNA and gamma proteins in a dose-dependent manner. However, the synthesis of viral beta proteins was significantly increased by ganciclovir in the later stage of infection.

As a novel heat shock protein 90 inhibitor, AT-533 exhibits various biological activities in vitro, including anti-viral, anti-tumor and anti-inflammatory activities. Moreover, gel, gel dosage form of AT-533, has been suggested to have anti-keratitis herpes simplex virus type-1 infection-induced effects on the skin lesions animals. However, safety evaluation has, best our knowledge, not examine...

OBJECTIVE To determine the effect of nonadherence to antiretroviral therapy (ART) on virologic failure and mortality in naive individuals starting ART. DESIGN Prospective observational cohort study. METHODS Eligible individuals enrolled in the Swiss HIV Cohort Study, started ART between 2003 and 2012, and provided adherence data on at least one biannual clinical visit. Adherence was defined...

Viral vectors are promising tools for gene therapy and vaccines. Viral vector-based vaccines can enhance immunogenicity without an adjuvant and induce a robust cytotoxic T lymphocyte (CTL) response to eliminate virus-infected cells. During the last several decades, many types of viruses have been developed as vaccine vectors. Each has unique features and parental virus-related risks. In additio...

A study has been made of the immunospecific, apple-green staining patterns imparted by fluorescent antibody to Rous virus in frozen sections of wing tumors produced in young chickens by various initiating doses of virus. Variations in the cellular site (cytoplasm, cell membrane, and nucleus), the distribution (particulate or homogeneous), and the quantity (little or much) of Rous viral antigens...

Viral infections, including Newcastle disease (ND), constitute a major health problem in the rapidly growing poultry industry of Nepal. Despite regular vaccination commercial farms, ND virus (NDV) outbreaks are frequently reported raising concern over safety and immunogenicity live-attenuated vaccines being used. This study was performed to compare four commercially available Nepal after admini...

Viral transmission pathways have profound implications for public safety; it is thus imperative to establish a complete understanding of viable infectious avenues. Mounting evidence suggests SARS-CoV-2 can be transmitted via the air; however, this has not yet been demonstrated. Here we quantitatively analyze virion accumulation by accounting aerosolized emission and destabilization. Reported su...

BACKGROUND Recurrent episodic wheeze in association with viral upper respiratory tract infection (URTI) is a specific clinical illness distinct from persistent atopic asthma. OBJECTIVES The objective of this review was to identify whether corticosteroid treatment, given episodically or daily, is beneficial to children with viral episodic wheeze. SEARCH STRATEGY We searched the Cochrane Airw...

The 2004 Asian H5N1 epizootic outbreak indicates the urgent need for vaccines against highly pathogenic avian influenza (HPAI) virus. The manufacture of inactivated whole-virus vaccines from HPAI viruses by traditional methods is not feasible for safety reasons as well as technical issues. The low pathogenic avian influenza A/wild bird feces/CSM2/02 (H5N3) virus was used as a heterologous neura...
