We give some extensions of the beautiful 1968 fixed point theorem Maia [Maia, M. G. Un’osservazione sulle contrazioni metriche. (Italian) Rend. Sem. Mat. Univ. Padova 40 (1968), 139–143] to three classes enriched contractive mappings in Banach spaces: contractions, Kannan contractions and Ćirić-Reich-Rus contractions.

In this paper, we introduce some new types of extended Geraghty contractions, called (?,?)-admissible generalized F-contractions, and prove fixed point results for such contractions in the setting partial b-metric spaces. Moreover, based on obtained property symmetry, inaugurate a result graphic F-contractions defined metric spaces endowed with directed graph. As an application, examine existen...

background pycnocycla spinosa decne. ex boiss is an aromatic plant which showed relaxant effects on isolated ileum contractions and antidiarrheal activity. thirty four components have been extracted from p. spinosa essential oil, of which several major constituents were found to show seasonal variation. objectives the aim of this work is to evaluate the diurnal variation of its oil constituents...

background: punica granatum linn. (pg) is native to the mediterranean region. its flower exhibited antioxidant activity. the present study attempt to investigate the effect of these extract on uterine contraction and its possible mechanism(s). methods: thirty five female wistar rats (200-300 g) at estrous phases of cycle was examined in this study; pieces of virgin adult rat uterus (1.5 cm) wer...

One mechanism by which the female sex may protect against elevated coronary vascular tone is inhibition of Ca2+ entry into arterial smooth muscle cells (ASMCs). In vitro findings confirm that high estrogen concentrations directly inhibit voltage-dependent Cav 1.2 channels in coronary ASMCs. For this study, we hypothesized that the nonacute, in vitro exposure of coronary arteries to a low concen...
