Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

open access: yesMolecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Common Fixed Point Theorems in Menger Probabilistic Quasimetric Spaces

open access: yesFixed Point Theory and Applications, 2009

Common Fixed Point of Four Mappings Satisfying Implicit Generalized Weak Contractive Type Condition

open access: yesDemonstratio Mathematica, 2014
In this paper, common fixed point for four maps using an implicit contractive condition in a complete metric space is proved. Some periodic point results for such mappings are also obtained.

GENERAL FIXED POINT THEOREMS FOR WEAKLY COMPATIBLE MAPS

open access: yesDemonstratio Mathematica, 2005
Summary: The purpose of this note is to use general expansive and conditions minimal type commutativity without continuity requirements to prove some fixed point theorems. The theorems extend known results from the class of compatible continuous expansive maps to a wider class of mappings.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Fisher-Type Fixed Point Results in b-Metric Spaces

open access: yesMathematics, 2019
In this paper, we prove some common fixed-point theorems for two self-mappings in the context of a complete b-metric space by proposing a new contractive type condition. Further, we derive a result for three self-mappings in the same setting.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Greguš type fixed points for weakly compatible maps

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 2003
Two self maps \(A\) and \(S\) of a normed space \(X\) are called weakly compatible if \(Ax=Sx\) implies \(ASx=SAx\). Let \(F\) be the family of mappings \(\varphi:\mathbb{R}^{+}\rightarrow\mathbb{R}^{+}\) which are upper semicontinuous, nondecreasing and satisfying \(\varphi(t)0\).

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.
