The 350-kDa sperm-binding protein (SBP), a species-specific sperm-binding protein, is localized in the vitelline layer of sea urchin eggs. In this study, we have shown for the first time that sperm gangliosides are ligands for the intact glycosylated SBP. Using recombinant fragments of the SBP, the N-terminal heat shock protein 110-like domain was shown to be responsible for the binding. The in...

BACKGROUND We sought to determine which systolic blood pressure (SBP) characteristics are associated with reduced brain integrity and whether these associations are stronger for white or gray matter. We hypothesized that exposure to higher and variable SBP will be associated with lower structural integrity of both gray and white matter. METHODS Neuroimaging, SBP, and cognition were obtained i...

BACKGROUND To evaluate association of 24 h-systolic blood pressure (SBP) variability and obstructive sleep apnea (OSA) as defined by the apnea-hypopnea index ≥5/h; and association of 24 h-SBP variability and prevalent cardiovascular disease (CVD) in OSA patients. METHODS Participants underwent polysomongraphy to evaluate the presence of OSA, and 24 h-ambulatory blood pressure monitoring was a...

Summation-by-parts (SBP) operators are finite-difference operators that mimic integration by parts. The SBP operator definition includes a weight matrix that is used formally for discrete integration; however, the accuracy of the weight matrix as a quadrature rule is not explicitly part of the SBP definition. We show that SBP weight matrices are related to trapezoid rules with end corrections w...

It has been previously reported that at treadmill exercise testing an abnormal ratio of recovery systolic blood pressure (SBP) to peak exercise SBP is more sensitive than exercise-induced angina or ST segment depression for diagnosing coronary artery disease (CAD). To investigate whether the SBP ratio keeps its diagnostic value during upright bicycle exercise, we evaluated the ratio of postexer...

BACKGROUND/AIMS The diagnosis of spontaneous bacterial peritonitis (SBP) is based on a polymorphonuclear leukocytes (PMNs) exceeding 250/μL in ascitic fluid. The aim of the study was to evaluate serum procalcitonin and ascitic fluid calprotectin as accurate diagnostic markers for detecting SBP. METHODS Seventy-nine patients with cirrhotic ascites were included. They were divided into a SBP gr...

We prospectively assessed the association of systolic blood pressure (SBP) after exercise with the risk of an acute myocardial infarction. Limited information exists currently on the role of SBP during recovery period with the risk of acute myocardial infarction. SBP was measured every 2 minutes during and after a progressive cycle ergometer exercise test in a representative sample of 2336 men ...

Introduction: Systems-Based Practice (SBP) is one of the sixcompetencies introduced by the ACGME for physicians toprovide high quality of care and also the most challenging of themin performance, training, and evaluation of medical students.This concept analysis clarifies the concept of SBP by identifyingits components to make it possible to differentiate it from othersimilar concepts. For prop...

The present study was performed to investigate the effect of commercial and operational factors on competitiveness improvement of Shahid Beheshti Port (SBP) in Chabahar in attracting shipping lines. The research method is applied in terms of purpose. Initially, the researcher conducted the qualitative phase to identify important variables, create a typology, or make new theories. To reach the s...
