Xia Y, Khalil RA. Sex-related decrease in [Ca ]i signaling and Ca -dependent contraction in inferior vena cava of female rat. Am J Physiol Regul Integr Comp Physiol 298: R15–R24, 2010. First published October 28, 2009; doi:10.1152/ajpregu.00465.2009.—Sex differences in the incidence of varicose veins have been suggested; however, the venous mechanisms involved are unclear. We hypothesized sex-r...

In this paper, we introduce the concept of contractive pair maps and give some necessary sufficient conditions for existence uniqueness best proximity points such pairs. our approach, have been weakened. An application has presented to demonstrate usability results. Also, cyclic ?-contraction asymptotic convergence theorems on point mappings. The results extend, generalize improve known from th...

This paper?s objective is to put forward anewkind of E?type contraction, which includes rational expression, by considering Proinov type functions and CG?simulation functions. contraction termed as a Suzuki-Proinov generalized (?,Z* E)?contraction mapping. Further, some common fixed point theorems using these new mappings, are triangular ??admissible pairs, demonstrated in the setting modular b...

We study the joint asymptotic behavior of the space requirement and the total path length (either summing over all root-key distances or over all root-node distances) in random m-ary search trees. The covariance turns out to exhibit a change of asymptotic behavior: it is essentially linear when 3 6 m 6 13 but becomes of higher order when m > 14. Surprisingly, the corresponding asymptotic correl...

Sex differences in the incidence of varicose veins have been suggested; however, the venous mechanisms involved are unclear. We hypothesized sex-related differences in venous function and underlying distinctions in intracellular free calcium, [Ca(2+)](i), signaling and Ca(2+)-dependent mechanisms of venous contraction. Circular segments of inferior vena cava (IVC) from male and female Sprague-D...

Geodesic contraction in vector-valued differential equations is readily verified by linearized operators which are uniformly negative-definite the Riemannian metric. In infinite-dimensional setting, however, such analysis generally restricted to norm-contracting systems. We develop a generalization of geodesic rates Banach spaces using smoothly-weighted semi-inner product structure on tangent s...

BACKGROUND The authors investigated the extent and cellular mechanisms by which the intravenous anesthetic ketamine alters acetylcholine-induced contraction in pulmonary veins (PVs). They tested the hypothesis that ketamine inhibits acetylcholine contraction in PVs. METHODS Canine PV rings with endothelium (E+) and without endothelium (E-) were isolated for measurement of isometric tension. T...
