OBJECTIVES Abnormal task-related activation and connectivity is present in schizophrenia. The aim of this study was the analysis of functional networks in schizophrenia patients in remission after the first episode. EXPERIMENTAL DESIGN Twenty-nine male patients in remission after the first episode of schizophrenia and 22 healthy controls underwent examination by functional magnetic resonance ...

Patients with non-alcoholic fatty liver disease (NAFLD) have impaired health-related quality of life including physical and mental state. Near-infrared spectroscopy (NIRS) is a useful tool for evaluation of brain activity and depressive state. This study aimed to determine the brain activity of female NAFLD patients using NIRS. Cerebral oxygenated hemoglobin (oxy-Hb) concentration during a verb...

One of the most characteristic features of glass-forming liquids is the sharp slowing down of relaxation times, τ, upon cooling. In these materials relaxation dynamics exhibit a non-Arrhenius temperature dependence usually described by Vogel-Fulcher-Tamman (VFT) relation [1]. However, for majority of glassforming liquids it is impossible to fit data in the entire temperature range with a single...

In this paper, the nonlinear mapping relation between the transient energy margin and the generator power at different fault clearing time and load levels was established by using the self-organizing feature map. Lyapunov’s direct method was used as a fast method to obtain the training set of the neural network. The transient security power limits of the generator at different fault clearing ti...

BACKGROUND The aim of this study is to evaluate the effect of Ramadan intermittent fasting on metabolic markers, dietary intake, anthropometric measurements, and abdominal visceral fat thickness (VFT) in pregnancy. METHODS Seventy-eight healthy pregnant subjects who had fasted for at least 15 days during the month of Ramadan in 2012 and 2013 and 78 controls were included in this study. Metabo...

The G-protein-coupled receptor (GPCR) activated by the neurotransmitter GABA is made up of two subunits, GABA(B1) and GABA(B2). GABA(B1) binds agonists, whereas GABA(B2) is required for trafficking GABA(B1) to the cell surface, increasing agonist affinity to GABA(B1), and activating associated G proteins. These subunits each comprise two domains, a Venus flytrap domain (VFT) and a heptahelical ...

A mathematical model for the binding and function of metabotropic glutamate receptors was developed, with the aim to gain new insights into the functioning of these complex receptors. These receptors are homodimers, and each subunit is composed of a ligand binding [Venus flytrap (VFT)] domain and a heptahelical domain (HD) responsible for G-protein activation. Our mechanistic model integrates a...

When the ultra high voltage (UHV) substation used the gas insulated switchgear (GIS) system to switch lines with capacitive current, the pre-breakdown and multiple reignition will occur between switching contacts. Because of discharge characteristics of SF6 and special structures of GIS system, the variations of the electromagnetic transient process and very fast transient overvoltage (VFTO) ar...

In recent years, gas-insulated switchgear (GIS) substations have become widely used in power systems. Due to their compact structure, extremely high oscillation frequencies are prone transient overvoltages or very fast (VFTOs) when the isolating switch circuit breaker is operated. The characteristics of these special processes GIS and effect hybrid reactive compensation (HRPC) on were studied. ...

To investigate the mechanism of chlorpromazine(CPZ)-induced ventricular arrhythmia, the changes in ventricular fibrillation threshold (VFT) were followed after intravenous injection of CPZ (1 mg/Kg) in dogs. Following injection, VFT was decreased to 56.6 +/- 5.4% (mean +/- SE) of the initial level. Since flavin-adenine-dinucleotide (FAD) combines specifically with CPZ in vitro, we investigate w...
