BACKGROUND Dilatation of the intercellular spaces by electron microscopy has been considered as an early morphological marker of tissue injury in gastroesophageal reflux disease. The degree of dilatation in Barret's esophagus in currently unknown. OBJECTIVES To determine the frequency of dilated intervellular spaces in Barrett's esophagus. MATERIAL AND METHODS Cross-sectional and prospectiv...

RATIONALE Telomerase is a nuclear regulator of telomere elongation with recent reports suggesting a role in regulation of mitochondrial reactive oxygen species. Flow-mediated dilation in patients with cardiovascular disease is dependent on the formation of reactive oxygen species. OBJECTIVE We examined the hypothesis that telomerase activity modulates microvascular flow-mediated dilation, and...

OBJECTIVES We sought to test the hypothesis that vascular endothelial function is impaired in Behçet's syndrome and reflects increased levels of oxidative stress. BACKGROUND Behçet's syndrome is a multisystem inflammatory disorder commonly complicated by vascular thrombosis and arterial aneurysm formation. The precise mechanisms underlying vascular disease in Behçet's syndrome are not known. ...

among the therapeutic options for achalasia are pneumatic dilatation (pd), an appropriate long-term therapy, and botulinum toxin injection (bt) that is a relatively short-term therapy. this study aimed to compare therapeutic effect of repetitive pneumatic dilation with a combined method (botulinum toxin injection and pneumatic dilation) in a group of achalasia patients who are low responder to ...

the objective of this paper is to establish a complete characterization of multiwavelet packets associated with matrix dilation on general lattices $gamma$ in $mathbb r^d$ by virtue of time-frequency analysis, matrix theory and operator theory.

Introduction: Post-dilatation is associated with a simultaneous expansion of the stents that enhances the angioplasty outcomes. However, increased risk of mortality and morbidity has been reported in patients with acute myocardial infarction (AMI) which has provoked considerable controversies concerning its efficiency. Materials and Methods: During a two-...

the aim followed in the present study was to evaluate the effect of estradiol (e2) injection and injection (either intramuscular (i.m) or intravenous (i.v)) of various doses of oxytocin (ot) on cervix dilation and on conception rate in zandi ewes during late breeding season. sixty three ewes were randomly selected. in experiment 1, the ewes received 100 µl e2 and 12h later were divided and assi...

BACKGROUND Acupressure has been used frequently to improve labor, manage labor pain, and shorten delivery time. However, there has been little research-based evidence to support the positive effects of acupressure in the obstetric area and obstetric nursing. OBJECTIVES The aim of this study was to evaluate the effects of SP6 acupressure on labor pain and delivery time in primigravida women in...
