We investigated alterations in the ageing-related parameters: multiple-unit action potentials, Na(+), K(+)-ATPase activity, glutathione-s-transferase (GST) activity, glutathione peroxidase (GPx) activity, lipid peroxidation and lipofuscin contents in the brain regions cerebral cortex, striatum, hippocampus and thalamus, resulting from the chronic administration of aluminium chloride (AlCl3) in ...

— Various model parameter calculation equations of RF CMOS inductors are compared. The calculation equations are using as variables either Y, Z-parameters or S-parameters. Results are based on on-wafer RF S-parameter measurements of a 3.75 turn spiral inductor fabricated in AMIS 0.7 μm CMOS DM1P n-well technology. Results obtained with calculation equations for a differentially driven inductor ...

Objectives: Vitamin B12 is a micronutrient essential for appropriate neuro-cognitive, hemopoetic and cardiovascular function. This study was planned to find correlation between vitamin B12 deficiency and its clinical, haematological and electrophysiological parameters. Material and Methods: This study was a cross sectional study which included 125 patients who had attended Maharana Bhupal Govt....

A major challenge in computational biology is constraining free parameters in mathematical models. Adjusting a parameter to make a given model output more realistic sometimes has unexpected and undesirable effects on other model behaviors. Here, we extend a regression-based method for parameter sensitivity analysis and show that a straightforward procedure can uniquely define most ionic conduct...

INTRODUCTION Carpal Tunnel Syndrome (CTS) is the most common type of entrapment neuropathy. Conservative therapy is usually considered as the first step in the management of CTS. Low Level Laser Therapy (LLLT) is among the new physical modalities, which has shown therapeutic effects in CTS. The aim of the present study was to compare the effects of applying LASER and splinting together with spl...

Traditional studies of electrophysiological correlates of behavior contain inherent high variability resulting from the arbitrary choice of behaviors, brain locations, and wave parameters. The operant control of neural events is a formal and systematic approach to the study of prespecified parameters and components of brain activity as they encode behaviors. Two studies in which the electrical ...

Buthotus schach is one of the dangers scorpion in Iran that belong to the Buthidae family. Toxins are existing in venom scorpion, modulate the ion channels by blocking or opening the pore of the channel or by altering the voltage gating and useful as pharmacological tools. In the present study, we investigated the effect of venom and its obtained fractions by gel filtrations on electrophysiolog...

Objective: To evaluate the clinical and electrophysiological determinants of arrhythmia recurrence in patients undergoing internal atrial cardioversion for chronic atrial fibrillation (AF). Setting: Tertiary cardiac referral centre. Methods: 101 consecutive patients with failed external cardioversion or AF > 1 year underwent internal atrial cardioversion; once stable sinus rhythm (SR) was obtai...
