Objective. To evaluate spectral heart rate (HR) variation using short-term ECG recordings at rest and during the tilt table test. Methods. The values of spectral components of total power (TP), high-frequency power (HF), low-frequency power (LF) and LF: HF ratio were measured at rest and during the head-up tilt in patients with temporal lobe epilepsy (TLE) and their control subjects. Results. C...

purpose: to compare the effects of short-tem and long-term systemic corticosteroids in the treatment of confirmed ocular toxoplasmosis. methods: this randomized comparative clinical trial was performed on 69 patients with confirmed active ocular toxoplasmosis with typical clinical manifestations. the subjects were randomly assigned to receive either 10 days (group a, 33 cases) or 4-6 weeks (gro...

The larval neuromuscular synapse of Drosophila serves as an important model for genetic and molecular analysis of synaptic development and function. Further functional characterization of this synapse, as well as adult neuromuscular synapses, will greatly enhance the impact of this model system on our understanding of synaptic transmission. Here we describe a form of short-term synaptic depress...

Experimental autoimmune encephalomyelitis (EAE) is an instructive model for the human demyelinating disease multiple sclerosis. Lewis (LEW) rats immunized with myelin-basic protein (MBP) develop EAE characterized by a single episode of paralysis, from which they recover spontaneously and become refractory to a second induction of disease. LF 15-0195 is a novel molecule that has potent immunosup...

Heart rate variability (HRV) is the result of variation in time between two successive heart beats. HRV is the tool for investigation of healthy and diseased condition. It also reflects an influence of autonomic nervous system on function of heart. In this study, our aim is to distinguish normal sinus rhythm from atrial fibrillation and Supraventricular arrhythmia. Here the ECG signal is pre-pr...

This study examined chronic and short-term stress effects on heart rate variability (HRV), comparing time, frequency and phase domain (complexity) measures in 50 healthy adults. The hassles frequency subscale of the combined hassles and uplifts scale (CHUS) was used to measure chronic stress. Short-term stressor reactivity was assessed with a speech task. HRV measures were determined via surfac...

The aims of this study were 1) to evaluate whether subjects suffering from acute mountain sickness (AMS) during exposure to high altitude have signs of autonomic dysfunction and 2) to verify whether autonomic variables at low altitude may identify subjects who are prone to develop AMS. Forty-one mountaineers were studied at 4,559-m altitude. AMS was diagnosed using the Lake Louise score, and au...

Annual 2-drug, single-dose mass drug administration (MDA) to 80-90% of the eligible population for 4-6 years are pre-requisites for the successful elimination of lymphatic filariasis (LF) from endemic communities by interruption of transmission and eventual elimination of new infections. In an experimental intervention project on the control of LF in Villupuram district of Tamil Nadu state, Ind...

BACKGROUND To explore relevant associations between deviations in linear and nonlinear heart rate variability (HRV) scores, and short-term morbidity and mortality in patients undergoing hip-surgery after a fracture. METHODS 165 patients with hip fractures being admitted for surgery at two hospitals were included in a prospective cohort study. A short-term ECG was recorded within 24 hours of a...
