Here we prove a probabilistic contraction mapping principle in Menger spaces. This is in line with research in fixed point theory using control functions which was initiated by Khan et al. [Bull. Austral. Math. Soc., 30(1984), 1-9] in metric spaces and extended by Choudhury et al. [Acta Mathematica Sinica, 24(8) (2008), 1379-1386] in probabilistic metric spaces. An example has also been constru...

This paper is concerned with mixed monotone mappings in partially ordered cone metric spaces. We establish several fixed point theorems, which generalize and complement some known results. Especially, even in a partially ordered metric space, our main results are generalizations of the fixed point theorems due to Bhaskar and Lakshmikantham [T. Grana Bhaskar, V. Lakshmikantham, Fixed point theor...

INTRODUCTION The objective of this study was to assess the views of Tehran citizens in regard to donating their organs in case of brain death. METHODS In this cross-sectional study, conducted between February 2009 and November 2010, two interviewers contacted 1379 people through random digit dialing for phone interviews. Phone calls were made between 6 and 9 pmon a workday, and those reaching...

Abstract Background Idiopathic granulomatous mastitis (IGM) is challenging as it a rare disease with unknown etiology, risk factors difficult to establish, and controversies regarding its treatment. Here we describe demographic clinical characteristics of patients IGM diagnosed at cancer referral center, well the microbial isolates Methods We reviewed charts IGM, from 2004 2019. Males were excl...

To understand the molecular mechanism of ligand-induced gating of the inositol 1,4,5-trisphosphate (IP(3)) receptor (IP(3)R)/Ca(2+) release channel, we analyzed the channel properties of deletion mutants retaining both the IP(3)-binding and channel-forming domains of IP(3)R1. Using intrinsically IP(3)R-deficient cells as the host cells for receptor expression, we determined that six of the muta...
