Background: The present study was conducted to determine the prevalence of metabolic syndrome (Mets) in schizophrenic patients in a 6-month period of treatment with antipsychotic medication. Methods: In this study, 60 volunteer schizophrenic patients were included.  At the onset and 6 month after treated with antipsychotic medication, fasting blood sugar (FBS), serum triglyceride (TG), high de...

Background: Employees are considered as an at-risk group for obesity and its adverse outcomes, particularly cardiovascular diseases (CVD). The present study was conducted to assess the correlation of obesity indices with CVD risk factors among a group of medical university employees in Zahedan city, southeast of Iran. Methods: This cross-sectional study recruited 211 healthy employees of Zaheda...

In the frq-wc-based circadian feedback loops of Neurospora, two PAS domain-containing transcription factors, WHITE COLLAR-1 (WC-1) and WC-2, form heterodimeric complexes that activate the transcription of frequency (frq). FRQ serves two roles in these feedback loops: repressing its own transcription by interacting with the WC complex and positively upregulating the levels of WC-1 and WC-2 prote...

The basic algorithm is derived from the weak-commitment algorithm (WC) of Yokoo [17], which has been shown to outperform breakout and min-conflict backtracking on certain classes of problems. Weakcommitment search is that part of WC which results from removing the learning mechanism; this will be called WC-NL. WC-NL is coupled with learning-by-merging to form the new algorithm WC-NG. Experiment...

Interlocked feedback loops may represent a common feature among the regulatory systems controlling circadian rhythms. The Neurospora circadian feedback loops involve white collar-1 (wc-1), wc-2, and frequency (frq) genes. We show that WC-1 and WC-2 proteins activate the transcription of frq gene, whereas FRQ protein plays dual roles: repressing its own transcription, probably by interacting wit...

combustion synthesis has been used to produce fe-(ti,w)c composites. a simple reactor was designed which made it possible to ignite the samples under controlled atmosphere. samples with different w/ti ratio were ingnited under argon atmosphere by an electric arc and a self-propagating reaction was initiated in each sample. different composites such as wc in fe-ti matrix, wc+(ti,w)c in fe matrix...

The fracture and fatigue characteristics of several cemented carbide grades are investigated as a function of their microstructure. In doing so, the influence of binder chemical nature and content (Co and 76wt%Co-24wt%Ni), as well as carbide grain size on hardness, flexural strength, fracture toughness and fatigue crack growth (FCG) behavior is evaluated. Mechanical testing is combined with a d...
