BACKGROUND The purpose of this investigation was to determine if black tea extract (BTE), consisting primarily of flavanol compounds called theaflavins, could inhibit herpes simplex virus type-1 (HSV-1) infection in cultured A549 (human epithelial) and Vero cells. METHODS The effect of BTE both on A549 and Vero cultured cells and on HSV-1 was assessed by using phase contrast and fluorescent m...

Abstract Background The newly emerged technology, nanotechnology, represents a promising solution for many medical and industrial problems. Random targeting, resistance, side effects are the main disadvantages of available cancer chemotherapy which critical aspects needed to be managed. So aim study was suggest nanoparticles as an alternative therapy therapies through detecting cytotoxic effect...

We have found that cerulenin, an antibiotic that inhibits de novo fatty acid and cholesterol biosynthesis and fatty acylation of proteins, strongly inhibited the cytotoxicity of ricin, modeccin, Pseudomonas toxin, and diphtheria toxin in a brefeldin A (BFA)-resistant mutant of Vero cells (BER-40). The protective effect of cerulenin against ricin was also observed in two other BFA-resistant cell...

BACKGROUND Renal epithelial cell injury facilitates crystal adhesion to cell surface and serves as a key step in renal stone formation. However, the effects of cell injury on the adhesion of nano-calcium oxalate crystals and the nano-crystal-induced reinjury risk of injured cells remain unclear. METHODS African green monkey renal epithelial (Vero) cells were injured with H2O2 to establish a c...

BACKGROUND Morphological changes of the cells infected with rubella virus cannot be observed easily. Estimation of the size of the cultured cells can be a valuable parameter in this condition. This study was conducted to find answers to the following questions: How much time after infection with rubella virus, the volume and surface area of the Vero cells and their nuclei get started to change?...

Fattiviracin A1, showed potent antiviral activities against herpes simplex virus type 1 (HSV-1), varicella-zoster virus (VZV), influenza A virus and human immunodeficiency virus type 1 (HIV-1). It showed no cytotoxicity against Vero cells. Fattiviracin A1 exhibited no significant antibacterial or antifungal activities. Treatment of HSV-1 with fattiviracin A1 decreased its infectivity to Vero ce...

Persistent viral infections can render host cells resistant to superinfection with closely related viruses by largely uncharacterized mechanisms. We present evidence for superinfection exclusion in brains of Borna disease virus (BDV)-infected rats and in persistently infected Vero cells, and we suggest that acquired resistance to BDV is due to unbalanced intracellular levels of viral nucleocaps...

introduction: this study was started to improve in vitro blastocyst development and avoiding of blastocyst collapsment (no visibie cavity, returning of hatching blastocyst into zona pellucida, and tendency to degeneration). materials and methods: 24hrs one - cell mouse embryos were recovered from positive plug females and cultured in following canditions: experiments 1,2: during first 48hrs nmr...

The aim of this study was to determine the inhibitory action of alantolactone, a gradient of traditional Chinese medicine Inulae Radix (Tu-Mu-Xiang), on herpes simplex virus 1 (HSV-1). African green monkey kidney cells (Vero cells) were infected with HSV-1 and the protective effects of alantolactone on Vero cells were examined. At concentrations of 10(-6), 10(-7), and 10(-8) g/mL, alantolactone...
