Protein kinase C (PKC) activity is increased following hippocampal long-term potentiation (LTP; Akers et al., 1986). A similar increase in PKC activity is measured following the induction of a long-lasting potentiation with abbreviated high-frequency stimulation (HFS) in combination with PKC-activating phorbol esters (Colley et al., 1989). Because phorbol esters have no effect on the initial po...

vitamin e (alpha-tocopherol) is a potent and natural antioxidant. vitamin e is concentrated from soybean oil. the committee on fetus and newborn of the academy of the american of pediatrics endorsed 1 to 2 mg/dl as the normal range of serum tocopherol level. human infants are born with low stores of vitamin e, thus they require an adequate intake of vitamin e soon after birth. the optimum intra...

The damage created in SiO2 layers by low-energy Ar ions ~130 keV! and the reconstruction of the structure after various annealing steps have been characterized as a function of the implantation dose. Quantitative determinations of the damage produced have been performed from infrared spectroscopy. We show that two dose thresholds for damage are encountered: At 10 cm damage saturates and for dos...

We scrutinize the physical viability of minimal nonsupersymmetric SO(10) grand unified theory with scalar sector $\mathbf{45}\ensuremath{\bigoplus}\mathbf{126}\ensuremath{\bigoplus}{\mathbf{10}}_{\mathbb{C}}$, in which symmetry is broken by former two representations, and a realistic Yukawa supported last two. Alongside known issue relatively low scale (and thus overly fast proton decay) encoun...

introduction: in the kindling-induced seizure model, low and repeated electrical or chemical stimulations, can elevate the neural network excitability and induce epileptiform seizures. opioid receptors are widely distributed in different areas of the brain. on the other hand, morphine has paradoxical effects and induces elevation or alleviation of the pain sensation and excitability, at differe...

objectives: turnip leaf has been used in folk medicine of iran for the treatment of diabetes. however,so far no scientific study has been done to support its use in traditional medicine. the present study was carried out to evaluate the possible hypoglycemic efficacy of aqueous extract of turnip leaf (aetl) in diabetic rats. materials and methods: alloxan-induced diabetic rats were orally treat...
