antviral/necrosis

Tomato is an important vegetable crop which is severely affected by Groundnut bud necrosis virus (GBNV). Until now effective antiviral agents have not been reported for the management of necrosis disease caused by GBNV. Therefore, a study was undertaken to manage the necrosis disease caused by GBNV

OBJECTIVE To describe a case of progressive outer retinal necrosis syndrome, successfully treated with a new combination of antiviral drugs. METHODS The patient was treated with a combined therapy of antiviral drugs that includes: intravenous acyclovir 10 mg/kg, three intravitreal injections of

Infectious hematopoietic necrosis virus (IHNV) causes high mortality in several economically important salmonid fishes, but there is no approved therapy up to now. To address the urgent need for therapeutics to combat IHNV infection, we investigate the anti-IHNV activities of 14 common antiviral

This study confirms our earlier finding that human interleukin (IL)-1 beta exerts an antiviral effect on diploid fibroblasts and on MG-63 osteosarcoma cells. It also extends the observation in that a similar effect was noted on aged but not freshly trypsinized HEp-2 cells, and that not only IL-1

The recently developed hepatitis C virus (HCV) subgenomic replicon system was utilized to evaluate the efficacy of several known antiviral agents. Cell lines that persistently maintained a genotype 1b replicon were selected. The replicon resident in each cell line had acquired adaptive mutations in

Infectious hematopoietic necrosis (IHN) caused by the viral pathogen infectious hematopoietic necrosis virus (IHNV) is a highly contagious disease of salmonid species, resulting in significant economic impact. The previous study showed a hydroxycoumarin derivative 7-[6-(2-methylimidazole) hexyloxy]

There is no consensus on the optimal antiviral regimen in the management of acute retinal necrosis, a disease caused by herpetic viruses with devastating consequences for the eye. The current gold standard is based on retrospective case series. Because the incidence of disease is low, few

OBJECTIVE Hepatitis C virus (HCV) is the major causal agent of non-A, non-B hepatitis and the leading indication for liver transplantation worldwide. The emerging field of immunogenetics has confirmed the significant role of heritability in host immune responses to infectious pathogens. Both the

Antimicrobial peptides, small cysteine-rich molecules, play vital roles in host defense mechanisms against pathogen infection. Recently, tilapia hepcidin (TH)1-5, was characterized, and its antimicrobial functions against several pathogens were reported. Herein, we investigated the antiviral

Virus-specific cytotoxic T lymphocytes (CTL) mediate their antiviral activity either by direct lysis of infected cells, or by the release of soluble lymphokines, or by a combination of the two. We have examined the role played by interferon-gamma (IFN-gamma) and tumour necrosis factor (TNF alpha) in

The natural antiviral immunity of human lymphocytes, leukocytes from peripheral blood and whole-blood cultures was studied using the method of infection with two viruses belonging to different taxonomic groups, vesicular stomatitis virus (VSV) and encephalomyocarditis virus (EMCV). The kinetics of

In vivo administration of exogenous cytokines may influence elicited immune responses, and hence may change the efficacy of a vaccine. We investigated the effects of tumour necrosis factor-alpha (TNF-alpha), interleukin-1 alpha (IL-1 alpha), interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) on

Tumor necrosis factor alpha (TNF-alpha) is overexpressed during human immunodeficiency virus (HIV) infection. RP 55778, a TNF-alpha synthesis inhibitor, decreases HIV replication in monocytes/macrophages. Therapeutic use of RP 55778 in vivo, like that of other biological response modifiers, would

OBJECTIVE To report a case of Acute Retinal Necrosis (ARN)-developed nephrotoxicity during intravenous acyclovir treatment and toxic hepatitis during oral valacyclovir treatment. METHODS Interventional case report. METHODS Retrospective chart review. RESULTS A 45-year-old male with ARN treated with

The antiviral action of recombinant human tumor necrosis factor (TNF) was studied using assay systems to determine inhibition of viral cytopathic effect (CPE), as well as suppression of virus growth measured by plaque assays. TNF was cloned and prepared by Asahi Chemical Industry, Japan. Antiviral
