The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Comprehensive study of photon and proton interactions to interpret the radiation parameters of boron derivative drugs for chemoradiotherapy

Journal of Nigerian Society of Physical Sciences
 For chemoradiotherapy applications, this work investigated the photon and proton interaction parameters in five boron-based medications: sodium borocaptate, bortezomib, delanzomib, boronophenylalanine, and boric acid. Photon interaction parameters such

Limits of atomic entanglement by cavity-feedback : from weak to strong coupling

, 2015
We theoretically investigate the entangled states of an atomic ensemble that can be obtained via cavity-feedback, varying the atom-light coupling from weak to strong, and including a systematic treatment of decoherence.

Unitary Gate Synthesis for Continuous Variable Systems [PDF]

, 2003
We investigate the synthesis of continuous-variable two-mode unitary gates in the setting where two modes A and B are coupled by a fixed quadratic Hamiltonian H.

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

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 ...

A photoionization model of the compact HII region G29.96-0.02 [PDF]

, 2002
We present a detailed photoionization model of G29.96-0.02 (hereafter G29.96), one of the brightest Galactic Ultra Compact HII (UCHII) regions in the Galaxy. This source has been observed extensively at radio and infrared wavelengths.

Effective atomic numbers of some composite mixtures including borax

Annals of Nuclear Energy, 2010
Abstract Effective atomic numbers for (PbO and Na 2 B 4 O 7 10H 2 O) and (UO 2 (NO 3 ) 2 , and Na 2 B 4 O 7 10H 2 O) mixtures against changing contents of PbO, Na 2 B 4 O 7 10H 2 O, and UO 2 (NO 3 ) 2 were measured in the X-ray energy range from 25.0 to 58.0 keV.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...
