Left ventricular cineangiograms of 105 patients with chest pain were digitised frame by frame and local endocardial movement displayed in order to study events during isovolumic contraction. Of these patients, 90 had coronary artery disease and the remainder were considered normal. In normal subjects, there was a 6 per cent reduction in cavity area before the onset of aortic valve opening, caus...

The main objective of this work is to introduce a new type non-linear contraction via C-class functions by using ?-admissible mapping. Our results extend and generalize the very recent Karapinar Sadarangani (2015. RACSAM. [37]). Illustrative examples are given support our findings. We have shown that satisfy periodic fixed point after modifying contraction. Next, we findings from self-mapping T...

BACKGROUND Rodents express two isoforms of the angiotensin II type 1 (AT(1)) receptor: AT(1A) and AT(1B). It is unclear which receptor subtype mediates contraction in response to angiotensin II in various arteries. We tested the hypothesis that the AT(1B) receptor is the predominant receptor that mediates contraction in the abdominal aorta in response to angiotensin II. METHODS Isometric tens...

The Meir-Keeler contraction, an important generalization of the classical Banach contraction has received enormous attention during the last four decades. In this paper, we present a review of Meir-Keeler type fixed point theorems and obtain some results using general Meir-Keeler type conditions for a sequence of maps in a metric space. Further, a recent result of Meir-Keeler type common fixed ...

Vasodilating agents were tested on smooth-muscle strips of small arterial blood vessels of dog and rabbit skin and mesentery, and two patterns of reaction were demonstrated. The type 1 vasodilating agents, for example nicotinate, caused relaxation of contracted strips or blocked their contraction. The type 2 vasodilating compounds, histamine, choline esters, and bradykinin, either caused contra...

A Pavlovian-conditioning procedure may produce modifications in multiple behavioral responses. As an example, conditioning may result in the elicitation of a specific somatomotor conditioned response (CR) and, in addition, other motor and visceral CRs. In the mollusk Hermissenda conditioning produces two conditioned responses: foot-shortening and decreased locomotion. The neural circuitry suppo...

Collagen gels are promising scaffolds to prepare an implant for cartilage repair but several parameters, such as collagen concentration and composition as well as cell density, should be carefully considered, as they are reported to affect phenotypic aspects of chondrocytes. In this study we investigated whether the presence of collagen type I or II in gel lattices affects matrix contraction an...

In this paper, we give a generalization of Hicks type contractions and Golet type contractions on fuzzy metric spaces. We prove some fixed point theorems for this new type contraction mappings on fuzzy metric spaces.

In this article, the notion of rational interpolative Meir-Keeler type contraction is discussed. The existence and uniqueness a fixed point for Das-Gupta are investigated. obtained results improve generalize existing on topic in recent literature.
