BACKGROUND Supply of sulfhydryl groups with the administration of N-acetylcysteine (NAC) has been reported to reverse tolerance to nitroglycerin but not to isosorbide dinitrate (ISDN). Lack of interaction between NAC and ISDN was suggested as an explanation for these findings. The present study was therefore designed to further evaluate this hypothesis. For this purpose, we compared the hemodyn...

The purpose of this study is to investigate the effect of sit to stand motion on the muscle activity of lower extremities muscles by the different type of chair and posture. Total 52 healthy adult between 19 and 26 were selected as subject for the study. The muscle activities of vastus lateralis, rectus femoris, vastus medialis, tibialis anterior and gastrocnemius by the different types of chai...

BACKGROUND Histopathologic features of the capsule may have an impact on the recurrence rate of pleomorphic adenomas. METHODS Retrospective (n = 154) and prospective (n = 64) histologic analysis of the capsular characteristics such as incompleteness, tumor penetration, pseudopodia, and satellite tumors of 218 pleomorphic adenomas. RESULTS In 160 of the 218 (73%) pleomorphic adenomas, 1 or m...

The aqueous and ethanol extract of the plants and also its smoke was prepared in concentrations of 50 and 25 mg/mL. The bacteria Staphylococcus aureus, Strept...

OBJECTIVE To assess how sociodemographic and activity behaviors contribute to adolescent body mass index (BMI). METHODS One hundred and thirteen adolescents (M = 17 years; 42% Caucasian, 56% African American) were assessed on BMI. Teens reported activity levels and caregivers reported socioeconomic status (SES). RESULTS Adolescents from lower SES backgrounds, and from minority groups, had h...

Twenty young asymptomatic diabetic patients were evaluated for left ventricular dysfunction by determining the radionuclide ejection fraction response to supine bicycle ergometry. The double product at peak exercise (28,743 +/- 3,314 vs 29,007 +/- 3,625, p greater than .05) was not significantly different between the two groups. Seven of 20 diabetics had either no change or a drop in their ejec...

We study diffusion (random walks) on recursive scale-free graphs and contrast the results to similar studies in other analytically soluble media. This allows us to identify ways in which diffusion in scale-free graphs is special. Most notably, scale-free architecture results in a faster transit time between existing nodes when the network grows in size; and walks emanating from the most connect...

The nuclease described by Carell, E.F., Egan, J.M. and Pratt, E.A. [Arch. Biochem. Biophys. (1970) 138, 26-31] has been purified 1000-fold from Euglena gracilis strain Z. The enzyme catalyzes the hydrolysis of both polyribonucleotides and polydeoxyribonucleotides. The relative rates of hydrolysis of synthetic and natural polynucleotides was found to be: poly (U) 100, poly (dT) 33, denatured cal...

Article history: Received on: 03/04/2016 Revised on: 05/05/2016 Accepted on: 30/06/2016 Available online: 26/09/2016 Marine algae are potential sources of biologically active compounds with antiviral, antimicrobial and anticancer activities. Two species of marine algae, Padina boryana Thivy and Enteromorpha sp were collected from the Red Sea. Both species were extracted with ethanol, acetone, a...
