Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Observational Properties of β Cephei Stars: 88 New Samples Discovered Based on TESS and Gaia Data

open access: yesThe Astrophysical Journal Supplement Series
We present a systematic investigation of β Cephei (BCEP) stars by integrating photometric data from the Transiting Exoplanet Survey Satellite (TESS) with astrometric parameters from Gaia Data Release 3.

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

A statistical study of pulsating stars. First paper The variable stars in a Centauri

open access: yesCommunications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1956
A large number of the variables in w Çent, has been analysed by the autocorrelation and subsequent power series method. In th a t way the intensities of the fundam ental and of the various overtones are ob- tained. Subject of th is study is especially the relative in ten sity A(2) of the first overtone.

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

The RR Lyrae Luminosity Metallicity Relation Revisited

open access: yesThe Astronomical Journal
We utilize a set of internally consistent absolute ages for a sample of ten Galactic globular clusters to determine the variation of the slope with the zero point of the M _V (RR) ∼ [Fe/H] relation for RR Lyrae variables.

ON THE MAGNETIC VARIABILITY OF PULSATING STARS

open access: yesOdessa Astronomical Publications, 2017
The variations of the effective magnetic field strength of the magnetic stars a 2 CVn, b CrB and of the pulsating stars RR Lyr and V 474 Mon are studied on the base of the spectrograms obtained at the 6-m telescope. The variation with the phase of the 0d.567 pulsating period was found in R Lyr.

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription

open access: yesFEBS Open Bio, EarlyView.
In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.

Variable Blue Straggler Stars in the Open Cluster NGC 6819 Observed in the Kepler “Superstamp” Field

open access: yesThe Astronomical Journal, 2023
NGC 6819 is an open cluster of age 2.4 Gyr that was in the NASA Kepler spacecraft’s field of view from 2009 to 2013. The central part of the cluster was observed in a 200 × 200 pixel “superstamp” during these four years in 30 minute cadence photometry ...
