background differences in causes, severities, areas of stenosis, and the association with swallowing and phonation of larynx and trachea can result into laryngotracheal stenosis (lts).this study evaluated the healing effect of bone marrow stem cells (bmscs) in experimentally induced lts dog model. methods seven dogs were enrolled. bmscs were isolated from proximal humerus and shoulder of a dog ...

abstract   introduction: inflammation and wear debris may be responsible for bone lysis and subsequent lost in aseptic arthroplasty. prostaglandin e2, platelet activating factor, and histamine are important mediators of inflammatory cells. we studied histopathological changes of cement-bone interface after using specific antagonists of these mediators.   methods: left and right tibiae of 120 ra...

this study was performed to evaluate the efficacy of injection of essential oil of eugenia caryophyllata in the kid horn buds, as a new chemical technique for disbudding. five-day-old healthy goat kids from both sexes (n = 16) were divided randomly into 4 equal groups. in groups 1, 2 and 3, 0.2 ml of clove essence and in group 4 (control) 0.2 ml of normal saline was injected into the left horn ...

the main purpose of this paper is to establish a relation between universality of certain p-compactifications of a semitopological semigroup and their corresponding enveloping semigroups. in particular, we show that if we take p to be the property that the enveloping semigroup of a compactification of a semitopological semigroup s is left simple, a group, or the trivial singleton semigroup, the...

Autism is a neurodevelopmental disorder originating from early childhood; nevertheless, its diagnosis is in older ages. In addition to heredity, environmental factors are also of great significance in the etiology of the disease. Dermatoglyphic patterns, albeit varied, remain stable for a lifetime and yield a large number of patterns upon examination. Studies have shown a significant associatio...

HYPOTHESIS Few studies have investigated the results of research focused on living-donor adult liver transplantation. Different characteristics between right- and left-lobe grafts have not yet been clarified in living-donor adult liver transplantation. Left-lobe graft remains an important option, even in adult recipients. SETTING A single liver transplantation center with a long history of he...

introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...

BACKGROUND Observational studies suggest that conventional right ventricular apical pacing may have a deleterious effect on left ventricular function. In this study, we examined whether biventricular pacing is superior to right ventricular apical pacing in preventing deterioration of left ventricular systolic function and cardiac remodeling in patients with bradycardia and a normal ejection fra...
