A transactional model examining the longitudinal association between vagal regulation (as indexed by vagal withdrawal) and maternal sensitivity from age 2.5 to age 5.5 was assessed. The sample included 356 children (171 male, 185 female) and their mothers who participated in a laboratory visit at age 2.5, 4.5, and 5.5. Cardiac vagal tone was obtained during a baseline task and during emotional ...

Introduction: Group A Beta-Hemolytic Streptococcus (GABHS) can induce PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). GABHS is the most important and common bacterial cause of acute pharyngitis in Iranian children. We studied the role of GABHS (anti-streptococcal antibodies) in suspected cases of PANDAS in a cross sectional studies. Method...

Until recently coccidioidin has been the only antigenic preparation available for detecting delayed dermal sensitivity induced by an experience with Coccidioides immitis. It is prepared from autolysates of the mycelial phase (saprophytic) of the fungus. A more sensitive reagent, spherulin, was developed in 1969 from the spherule phase (parasitic) of the organism. Use of spherulin showed that co...

A novel fiber Bragg grating (FBG) sensing-based acceleration sensor has been proposed to simultaneously decouple and measure temperature and acceleration in real-time. This design applied a diaphragm structure and utilized the axial property of a tightly suspended optical fiber, enabling improvement in its sensitivity and resonant frequency and achieve a low cross-sensitivity. The theoretical v...

Dr. Beatriz L. Gomez and colleagues described a new inhibition immunoassay for the diagnosis of histoplasmosis (1). My laboratory developed and extensively evaluated an antibody sandwich immunoassay for this purpose. It is important to contrast the two methods, as their performance characteristics differ. The characteristics of the assay developed in my laboratory are high sensitivity in dissem...

The cross-match test is an exact, distribution-free test of no treatment effect on a high-dimensional outcome in a randomized experiment. The test uses optimal nonbipartite matching to pair 2I subjects into I pairs based on similar outcomes, and the cross-match statistic A is the number of times that a treated subject was paired with a control, rejecting for small values of A. If the test is ap...

Background: Neonatal sepsis is a major cause of mortality and morbidity, especially in developing countries. The goal of the present study was to determine the bacterial etiology and antibiotic sensitivity patterns of neonatal sepsis. Methods: This cross sectional study was conducted on 208 neonates admitted with clinically suspected sepsis over a period of 30 months. Sepsis was divided into ea...

interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...
