Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Fixed points of rotations of n-sphere

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
We show that every rotation of an even-dimensional sphere must have a fixed point.

Fixed points for φE-Geraghty contractions

open access: yes, 2017
In this paper, we introduce the new concept of a generalization of contraction so-called φE-Geraghty contraction and we establish a fixed point theorem for such mappings in complete metric spaces. c ©2017 All rights reserved.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Some fixed points of expansion mappings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Wang et al. [11] proved some fixed point theorems on expansion mappings, which correspond some contractive mappings. Recently, several authors generalized their results by some ways.

Three-point fix tympanoplasty

open access: yesActa Oto-Laryngologica, 2015
The three-point fix tympanoplasty procedure is a stable and effective technique - with a high degree of graft take and satisfactory hearing results - for reconstruction of most tympanic membrane (TM) perforations.It is difficult to repair a TM perforation, including subtotal perforation, involving the anterior part of the annulus.
