pyridoxine dependent seizure have been recornized as a rare and important cause of intractable seizure in neonates and infants.prompt diagnosis and treatment can stop and prevent these seizure and consequential developmental disabilities.furthermore it can eliminate the unnecessary administration of anticonvulsant medications and thier side effects.the paitient was 7 months old infant who was r...

In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

corticosteroid resistant and dependent nephrotic syndrome in children is a challenge and there are some difficulties in treating such patients. we reviewed the current studies that evaluated therapeutic role of a relatively new immunosuppressive drug “rituximab” in reducing proteinuria and reduction of relapse rate in less than 16 year old patients with non-responsive or steroid dependent nephr...

  The involvement of NMDA receptors and voltage-dependent calcium channels in augmentation of long-term potentiation (LTP) was investigated at the Schaffer collateral CA1 pyramidal cell synapses in hippocampal slices of morphine dependent rats, using primed-burst tetanic simulation. The amplitude of the population spike and its delay were measured as indices of increase in postsynaptic excitabi...

Hysteresis loop curves are highly important for numerical simulations of materials deformation under cyclic loadings. The models mainly take account of only the tensile half of the stabilized cycle in hysteresis loop for identification of the constants which don’t vary with accumulation of plastic strain and strain range of the hysteresis loop. This approach may be quite erroneous particularly ...

in this paper mathematical structure of time-dependent lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent lagrangian systems are considered. starting point is time-independent lagrangian systems ,then we extend mathematical concepts of these systems such as equivalent lagrangian systems to the...

In some long term studies, a series of dependent and possibly truncated lifetime data may be observed. Suppose that the lifetimes have a common continuous distribution function F. A popular stochastic measure of the distance between the density function f of the lifetimes and its kernel estimate fn is the integrated square error (ISE). In this paper, we derive a central limit theorem for t...

introduction: the relation between morphine and nitric oxide release has been shown. due to important role of nitric oxide in regulation of skin blood flow, the aim of this study was to investigate the effect of nitric oxide synthase inhibitor (l-name) and nitric oxide synthesis precursor (l-arginine) on skin blood flow of intact and morphine-dependent rats. methods: skin blood flow of hind paw...

there is strong evidence demonstrating that nifedipine dissolved in ethanol selectively inhibits only l-type ca2+ current. in addition, acute ethanol exposure reduces voltage-dependent calcium currents. in the present study, we investigated the antagonistic effect of fixed concentration of nifedipine dissolved in different concentration of ethanol on l-type ca2+ current. in a na+-k+ free soluti...
