<b><i>Background:</i></b> Newborns delivered by elective cesarean section (CS) are at higher respiratory risk than those vaginally or CS proceeded labor (secondary CS). The oxytocin challenge test (OCT) induces uterine contractions that trigger the release of fetal hormones regulating lung fluid clearance during transition from to an air-breathing environment. <b>&...

The study evaluates knowledge, attitudes, and behaviour of mothers regarding the immunization of 841 infants who attended public kindergarten in Cassino and Crotone, Italy. Overall, 57.8% of mothers were aware about all four mandatory vaccinations for infants (poliomyelitis, tetanus, diphtheria, hepatitis B). The results of a multiple logistic regression analysis showed that this knowledge was ...

BACKGROUND The relationship between prostate-specific antigen (PSA)-defined recurrence and prostate cancer-specific mortality remains unclear. Therefore, we evaluated the hypothesis that a short post-treatment PSA doubling time (PSA-DT) after radiation therapy is a surrogate end point for prostate cancer-specific mortality by analyzing two multi-institutional databases. METHODS Baseline, trea...

WALLACE, ANDREW G., N. SHELDON SKINNER, JR., AND JERE H. MITCHELL. Hemodynamic determinants of the maximal rate of rise of left ventricular pressure. Am, J. Physiol. 205 (I) : 30-36. 1963. -The maximal rate of left ventricular pressure development (max. dp/dt) was measured in an arenexic preparation which permitted independent control of stroke volume, heart rate, and aortic pressure. Max. dp/d...

the development, survival, and reproduction of diamondback moth (dbm), plutella xylostella (l.), were studied in laboratory at 25±1°c, 65±5% rh and a 14l: 10d hours photoperiodism on five host plants of: cauliflower (brassica oleracea l. var. botrytis), two varieties of cabbage (b. oleracea l. var. capitata) namely ‘globe master’ and ‘scarlet ohara’, kohlrabi (b. oleracea l. var. gongylodes), a...

Diastolic function is a major determinant of ventricular performance, especially when loading conditions are altered. We evaluated biventricular diastolic function in lambs and studied possible load dependence of diastolic parameters [minimum first derivative of pressure vs. time (dP/dt(min)) and time constant of isovolumic relaxation (tau)] in normal (n = 5) and chronic right ventricular (RV) ...

A treatment of the diatom Phaeodactylum tricornutum with high light (HL) in the visible range led to the conversion of diadinoxanthin (Dd) to diatoxanthin (Dt). In a following treatment with HL plus supplementary ultraviolet (UV)-B, the Dt was rapidly epoxidized to Dd. Photosynthesis of the cells was inhibited under HL + UV-B. This is accounted for by direct damage by UV-B and damage because of...

Let (X, d, μ) be a metric measure space satisfying Q-doubling condition (Q > 1) and an L2-Poincaré inequality. $${\cal L} = {\cal + V$$ Schrödinger operator on X, where L}$$ is non-negative generalized by Dirichlet form, V Muckenhoupt weight that satisfies reverse Hölder RHq for some q ⩾ 1)/2. We show solution to $$({\cal - \partial _t^2)u 0$$ X × ℝ+ the Carleson $$\mathop {{\rm{sub}}}\limits_{...

Background Bronchopulmonary dysplasia (BPD) is one of the most common serious squeal of preterm infants. It involves approximately one quarter of infants with birth weight less than 1500 grams and 30% of less than 1000 grams. Vitamin A has been shown to reduce BPD rate. We compared efficacy of low and high doses of vitamin A for prevention of BPD in very low birth weight preterm infants. Materi...
