Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

The temporal and spatial evolution of the starburst in ESO 338-IG04 as probed by its star clusters

, 2003
In this paper we use ultra-violet (UV) and optical HST photometry in five bands, and an extensive set of spectral evolutionary synthesis scenarios to investigate the age and masses of 124 star clusters in the luminous blue compact galaxy ESO338-IG04 ...

GW230529: unveiling the hidden realm of the anisotropic neutron stars in the lower mass gap with gravitational wave echoes

European Physical Journal C: Particles and Fields
Recent discovery of a compact binary coalescence through GW230529 by LIGO has indicated the merger event of a compact object of mass between $$2.5{-}4.5~M_{\odot }$$ 2.5 - 4.5 M ⊙ with a neutron star of mass between $$1.2{-}2.0~M_{\odot }$$ 1.2 - 2.0 M ⊙

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.

Hair formation in the background of noncommutative reflecting stars

Nuclear Physics B, 2019
We investigate scalar condensations around noncommutative compact reflecting stars. We find that the neutral noncommutative reflecting star cannot support the existence of scalar field hairs.

Generalized compact star models with conformal symmetry

European Physical Journal C: Particles and Fields, 2021
We generate a new generalized regular charged anisotropic exact model that admits conformal symmetry in static spherically symmetric spacetime. Our model was examined for physical acceptability as realistic stellar models. The regularity is not violated,

PossibleExistence of Dark-Matter-Admixed Pulsar in the Disk Region of the Milky Way Galaxy

Universe, 2022
In our previous study, (Eur Phys J Plus 135:362, 2020 & Eur Phys J Plus 135:637, 2020), we have discussed the possible existence of the dark-matter-admixed pulsars, located in dwarf as well as in massive spiral galaxies (based on Singular Isothermal ...

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 ...

Upper bound on the radius of the innermost photonsphere in the regular compact star spacetime

European Physical Journal C: Particles and Fields
We study properties of the innermost photonsphere in the regular compact star background. We take the traceless energy–momentum tensor and dominant energy conditions.

Study of a Minimally Deformed Anisotropic Solution for Compact Objects with Massive Scalar Field in Brans–Dicke Gravity Admitting the Karmarkar Condition

Universe, 2023
In the present paper, we focused on exploring the possibility of providing a new class of exact solutions for viable anisotropic stellar systems by means of the massive Brans–Dicke (BD) theory of gravity.
