Novel polyvinylidene fluoride-carbon quantum dot polymer nanocomposite membrane for removal of antibiotics from water [PDF]

Royal Society Open Science
Carbon quantum dot (CQD)-based nanocomposites are widely used as fluorescent sensors for the detection of antibiotics in water; however, the use of CQDs for water remediation is largely unexplored.

Flash X-ray cinematography analysis of dwell and penetration of small caliber projectiles with three types of SiC ceramics

, 2016
In order to improve the performance of ceramic composite armor it is essential to know the mechanisms during each phase of the projectile–target interaction and their influence on the penetration resistance.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

XMM-Newton View of Pulsating Iron Fluorescent Emission from Centaurus X-3

The Astrophysical Journal
Centaurus X–3 (Cen X–3) is a bright, high-mass X-ray binary pulsar. We present a pulse phase–resolved X-ray spectral analysis of data from an archival XMM-Newton observation of Cen X–3 taken during the high state of the source.

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

Molecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Age-related cellular copper dynamics in the fungal ageing model Podospora anserina and in ageing human fibroblasts [PDF]

, 2009
In previous investigations an impact of cellular copper homeostasis on ageing of the ascomycete Podospora anserina has been demonstrated. Here we provide new data indicating that mitochondria play a major role in this process.

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

Molecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

AstroSat observations of eclipsing high mass X-ray binary pulsar OAO 1657-415

, 2021
We present the results obtained from analysis of two AstroSat observations of the high mass X-ray binary pulsar OAO 1657-415. The observations covered 0.681–0.818 and 0.808–0.968 phases of the ∼ 10.4 day orbital period of the system, in March and July ...
