correlation between sacral ratio and bowel function as well as fecal continence has been well documented in patients with anorectal malformations (arms). one hundred and twenty children with arms were investigated in this study. sacral ratio (sr) was measured from pelvic x-rays of patients. among these, 52 patients (43%) had no pelvic x-ray and were excluded from this study. sr was measured by ...

BACKGROUND The interaction between Mycobacterium tuberculosis (Mtb) and host cells is complex and far from being understood. The role of the different receptor(s) implicated in the recognition of Mtb in particular remains poorly defined, and those that have been found to have activity in vitro were subsequently shown to be redundant in vivo. METHODS AND FINDINGS To identify novel receptors in...

Background. Rickettsiosis has long been considered as a benign affection. Pathologic mechanisms and prognosis factors of severe forms are incompletely decrypted. In this perspective, we aimed to determine the predictive factors of a severe rickettsiosis (SR). Methods. We conducted a retrospective and prognostic study including all patients with documented rickettsiosis hospitalized between 1993...

background: one area of nanoscience deals with nanoscopic interactions between nanostructured materials and biological systems. to elucidate the effects of the substrate surface morphology and viscoelasticity on cell proliferation, fractal analysis was performed on endothelial cells cultured on nanocomposite samples based on silicone rubber (sr) and various concentrations of organomodified nano...

Abnormalities in cardiomyocyte intracellular calcium cycling, and specifically Ca2+ physiology of the sarcoplasmic reticulum (SR), in cardiac disease states have been an intense focus of research over the past 30 years. It is increasingly apparent that alterations of SR function may contribute to the pathophysiological changes observed in several cardiac diseases including chronic heart failure...

This paper presents a novel solution method for joint energy and Spinning Reserve (SR) dispatch problem. In systems in which the Lost Opportunity Cost (LOC) should be paid to generators, if the LOC is not considered in the dispatch problem, the results may differ from the truly optimum solution. Since the LOC is a non-differentiable function, including it in the formulation makes the problem so...

Over recent years, research on thiolate-protected gold clusters Au(m)(SR)n has gained significant interest. Milestones were the successful determination of a series of crystal structures (Au102(SR)44, Au25(SR)18, Au38(SR)24, Au36(SR)24, and Au28(SR)20). For Au102(SR)44, Au38(SR)24, and Au28(SR)20, intrinsic chirality was found. Strong Cotton effects (circular dichroism, CD) of gold clusters pro...

Calcium that induces contraction by interacting with the contractile proteins of muscle cells may be derived from different sources: extracellular space including the basement membrane, sarcoplasmic reticulum (SR) and, under certain circumstances, mitochondria." Among these sources of Ca for excitation-contraction coupling the contribution of the SR varies between different types of muscles: ca...
