preterm contraction of uterus is a main cause of miscarriages and preterm labour. euphorbia known as ferphion in iranian traditional medicine texts like al-hawi, is reported for prevention of preterm labour. therefore, the objective of this research was to investigate the effect of euphorbia spinidens bornm. ex prokh. on motility of rat uterus. uterine horns were isolated form non-pregnant fema...

in this paper direct proofs of some common fixed point results for two and three mappings under weak contractive conditions are given. some of these results are improved by using different arguments of control functions. examples are presented showing that some generalizations cannot be obtained and also that our results are distinct from the existing ones.

In this article, we introduce a new notion of proximal contraction, named as generalized S-proximal contraction and derive a common best proximity point theorem for proximally commuting non-self mappings, thereby yielding the common optimal approximate solution of some fixed point equations when there is no common solution. We furnish illustrative examples to highlight our results. We extend so...

In this paper we investigate a kind of boundary value problem involving a fractional differential equation.  We study the existence of positive solutions of the problem that fractional derivative is the Reimann-Liouville fractional derivative. At first the green function is computed then it is proved that the green function is positive. We present necessary and sufficient conditions for existen...

in this paper, we introduce intuitionistic fuzzy contraction mappingand prove a fixed point theorem in intuitionistic fuzzy metric spaces.

In this paper, at first, we introduce $alpha_{mu}$-admissible, $Z_mu$-contraction and  $N_{mu}$-contraction via simulation functions. We prove some new fixed point theorems for defined class of contractions   via $alpha$-admissible simulation mappings, as well. Our results  can be viewed as extension of the corresponding results in this area.  Moreover, some examples and an application to funct...

Introduction: Foot pronation can lead to different lower limb injuries. The purpose of this study was to investigate the effect of long-term training on sand on ankle joint co-contraction in individuals with pronated feet during walking. Methods: The present study was a randomised controlled clinical trial type. Statistical samples of the present study included 15 males with excessive pronated...

Introduction and aim: In the past few decades, exercise has been promoted with increasing interest for the treatment of back pain. Therefore, the present study aimed to investigate the effect of rehabilitation exercises with medicine beta balls on the directional and general contraction of ankle joint muscles in patients with low back pain during walking. Methods: The present study was a clini...
