The ability to develop efficient and versatile technologies for manipulating gene expression is a fundamental issue both in biotechnology and therapeutics. The endogenous RNA interference (RNAi) pathway which mediates gene ...

In toad olfactory neurons, a putrid odorant mixture inducing inhibitory responses increases Ca2+-activated K+ conductance, developing a hyperpolarizing receptor potential. Removal of extracellular Ca2+ or exposure to ...

Adolescent rats exhibit ethanol-induced locomotor activity (LMA), which is considered an index of ethanol's motivational properties likely to predict ethanol self-administration, but few studies have reported or correlated ...

The pathological alterations induced by neuwiedase, a 22 kDa class P-I metalloproteinase from the venom of the South American pit viper Bothrops neuwiedi, were studied in mice. Neuwiedase was devoid of hemorrhagic activity ...

The potential of yerba mate (Ilex paraguariensis) to induce chlorogenate hydrolase (EC 3.1.1.42, CHase) activity in different fungal strains has been investigated. CHase was highly induced in mycelia of Aspergillus niger ...

We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were ...

Efforts have been made to develop a chemoprevention that selectively triggers apoptosis in malignant cancer cells. Here, we demonstrated that a mutated Ha-Ras activity is required in Anisomycin-induced apoptosis in transformed ...
