This study evaluated the role of Ca2+ in spontaneous and ACh- and KCl-induced contractions in longitudinal and circular smooth muscle from rabbit small intestine in vitro. In the first experiment, the amplitude, frequency and tone of spontaneous contractions in longitudinal and circular smooth muscle of small intestine were determined and, in the second experiment, the ACh- and KCl-induced resp...

In this paper, we introduce orthogonal multivalued contractions, which are based on the recently introduced notion of orthogonality in metric spaces. We construct numerous fixed point theorems for these contractions. show how aid generalization a number published findings. Additionally, offer theorem that establishes existence fractional differential equation’s solution.

      The effects of hydroalcoholic extract of Peganum harmala seeds (EPS) on spontaneous rhythmic contractions of isolated rat uterine was investigated in this study. EPS was tested on the isolated uterus and endometrium free (i.e. stripped myometrium) preparations. EPS was found to exhibit significant spontaneous contractions of the uterus and stripped myometrium relative to the solv...

In this paper, we discuss the existence and uniqueness of fixed points for $G$-asymptotic contractions in metric spaces endowed with a graph. The result given here is a new version of Kirk's fixed point theorem for asymptotic contractions in metric spaces endowed with a graph. The given result here is a generalization of fixed point theorem for asymptotic contraction from metric s paces to metr...

Submodularity is an important  property of set functions with deep theoretical results  and various  applications. Submodular systems appear in many applicable area, for example machine learning, economics, computer vision, social science, game theory and combinatorial optimization.  Nowadays submodular functions optimization has been attracted by many researchers.  Pendant pairs of a symmetric...
