By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

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

Advances in Difference Equations, 2019 In this work, new conditions are obtained for the oscillation of solutions of the even-order equation (r(ζ)z(n−1)(ζ))′+∫abq(ζ,s)f(x(g(ζ,s)))ds=0,ζ≥ζ0, $$ \bigl( r ( \zeta ) z^{ ( n-1 ) } ( \zeta ) \bigr) ^{\prime }+ \int _{a}^{b}q ( \zeta ,s ) f \bigl( x

On the monotonic properties and oscillatory behavior of solutions of neutral differential equations
Demonstratio Mathematica, 2023 In this work, we study new asymptotic properties of positive solutions of the even-order neutral differential equation with the noncanonical operator. The new properties are iterative, which means they can be used several times.

FEBS Letters, EarlyView.Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Implicit second and third orders runge-kutta for handling discontinuities in delay differential equations [PDF]
, 2014 Implicit Runge-Kutta (RK) methods have been developed and implemented in solving Delay Differential Equations (DDEs) systems which often encounter discontinuities. These discontinuities might occur after and even before the initial solution.

, 2016 In this paper we report on the results of a numerical study of the nonlinear time-dependent Bardeen--Cooper--Schrieffer (BCS) equations, often also denoted as Bogoliubov--de--Gennes (BdG) equations, for a one-dimensional system of fermions with contact ...

Oscillation Theorems for Certain Even Order Nonlinear Damped Differential Equations
Rocky Mountain Journal of Mathematics, 2008 The authors establish sufficient conditions for the oscillation of all solutions of a certain even order half-linear damped differential equation. Main methods in proofs are integral averaging and Riccati techniques. It has to be noted that the question of the existence of solutions on the interval \([t_0,\infty)\) of this nonlinear differential ...
