textual coherence in cloudy semantic relations through which the relation is each piece of speech or writing acts as context. ma.k holliday and r.hassan played a key ale estabhshing the relationship in contchal shachre and the relationship among sentence elements. the believe that coherence applies to all kids of relations which link one element of the sentence to the element in previous senten...

Thirty-six young adult male baboons (Papio cynocephalus) were fed an atherogenic diet (40% calories from lard, 1.5 mg cholesterol/kcal) and taught to puff by operant conditioning with water rewards. Eighteen baboons (smokers) were assigned randomly to smoke 43 cigarettes a day, and 18 baboons (shams) were assigned randomly to puff air under conditions equivalent to those of the experimental gro...

Background: Patient safety is a worldwide concern with limited resources, recent healthcare systems are facing major factors in ensuring patient safety. Aim: This study aimed at investigating facilitators and barriers influencing as perceived by nurse interns. Research design: descriptive design was used. Setting: carried out two different faculties affiliated to Al-Azhar Ain-Shams universities...

BACKGROUND Systemic inflammation and coagulopathy are major drivers of injury progression following hemorrhagic trauma. Our aim was to examine the effect of small-volume 3% NaCl adenosine, lidocaine and Mg2+ (ALM) bolus and 0.9% NaCl/ALM 'drip' on inflammation and coagulation in a rat model of hemorrhagic shock. METHODS Sprague-Dawley rats (429±4 g) were randomly assigned to: 1) shams, 2) no-...

BACKGROUND The in vivo mechanism by which inhibition of NO synthase impairs ischemia-induced coronary vascular growth is unknown. We hypothesized that production of the growth inhibitor angiostatin increases during decreased NO production, blunting angiogenesis and collateral growth. METHODS AND RESULTS Measurements were made in myocardial tissue or interstitial fluid (MIF) from dogs undergoi...

Rats receiving intragastric infusions of 2.5, 5.0, 7.5, or 10.0 ml of normal saline while their pylori are reversibly occluded suppress meal size to the smallest infusion and display a dose-dependent reduction across volumes [Phillips, R. J., and T. L. Powley. Am. J. Physiol. 271 ( Regulatory Integrative Comp. Physiol.40): R766-R779, 1996]. To evaluate the contributions of the vagus to this det...

The reduction in Ca2+ concentration during diastole and relaxation occurs differently in normal hearts and in hypertrophied hearts secondary to pressure overload. We have studied some possible molecular mechanisms underlying these differences by examining the function of the sarcoplasmic reticulum and the expression of the gene encoding its Ca2(+)-ATPase in rat hearts with mild and severe compe...
