BACKGROUND Induction of heat-shock proteins (HSPs) results in cardioprotection against ischemic insult. Geranylgeranylacetone (GGA), known as an antiulcer agent, reportedly induces HSP72 in the gastric mucosa and small intestine of rats. The present study tested the hypothesis that oral GGA would induce HSP72 in the heart and thus render cardioprotection against ischemia/reperfusion injury in r...
A cyclic polyisoprenoid compound, geranylgeranylacetone (GGA), has been used as antiulcer drug. GGA is also a potent inducer of heat shock proteins (HSPs). HSPs are considered to induce an antiviral effect; however, the detailed mechanism is unknown. To determine whether GGA might show antiviral activity and what the mechanism is, the effect of GGA against influenza virus (strain PR8) infection...
Infectious bursal disease (IBD) is an acute, highly contagious, and immunosuppressive avian disease caused by IBD virus (IBDV). MicroRNAs (miRNAs) are involved in host-pathogen interactions and innate immune response to viral infection. However, the role of miRNAs in host response to IBDV infection is not clear. We report here that gga-miR-155 acts as an anti-virus host factor inhibiting IBDV r...
Absrract-This work IS a continuation of our earlier work on the Generalized Guard-zones Algorithm (GGA) for self-supervised parameter learning. An atlempt is made here for the automatic determination of the guard-zone parameter i' N (i.e. the threshold used for discarding doubtful or mislabeled samples) at every instant of learning, for the general m-elass N-featu re pattern recognition problem...
Acute ultraviolet (UV) B exposure causes photokeratitis and induces apoptosis in corneal cells. Geranylgeranylacetone (GGA) is an acyclic polyisoprenoid that induces expression of heat shock protein (HSP)70, a soluble intracellular chaperone protein expressed in various tissues, protecting cells against stress conditions. We examined whether induction of HSP70 has therapeutic effects on UV-phot...
BACKGROUND Geranylgeranylacetone (GGA), an anti-ulcer drug widely used in Japan, has attracted interest because of its various therapeutic effects. Therefore, we investigated the effects of GGA on human hepatic stellate cells (HSCs) in vitro and in a mouse model of liver fibrosis. METHODS LX2, an immortalized human HSC line, was cultured and treated with GGA at concentrations up to 0.5 mM. Af...
در این پایان نامه به بررسی فاز نارسانای توپولوژی و وارونی ترازهای انرژی در نوار انرژی برای ترکیبها ونانولایه های yaupb و yausn در بود و نبود ناخالصی mn با رهیافت های gga ,lda ,mbj-gga و ev-gga پرداخته شد. نتیجه ها نشان داد که در ترکیب yausn نوارهای و در نقطه ی جابجا نمی شوند و وارونی نواری رخ نمیدهد و دارای نظم نواری معمولی است. در حالی که در ترکیب yaupb نوارهای و در نقطه ی جابجا می شوند، به گو...
Mycoplasma gallisepticum (MG), one of the most pathogenic Mycoplasmas, can cause chronic respiratory disease (CRD) in chickens. It has been suggested that micro-ribonucleic acids (miRNAs) are involved in microbial pathogenesis. However, little is known about the roles of miRNAs in MG infection. Previously, we found by deep sequencing that gga-miR-19a was significantly up-regulated in the lungs ...
