Molecular Oncology, EarlyView.Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Freeze Out Process with In-Medium Nucleon Mass [PDF]
, 2006 We investigate the kinetic freeze out scenario of a nucleon gas through a finite layer. The in-medium mass modification of nucleons and it's impact on the freeze out process is studied.

, 2018 Mechanical properties of steels are significantly enhanced by retained austenite. Particularly, it has been shown that a recently developed heat-treatment technique called Quenching and Partitioning (Q\&P) stabilises austenite effectively. In the present

Directed sub-wavelength imaging using a layered metal-dielectric system [PDF]
, 2006 We examine some of the optical properties of a metamaterial consisting of thin layers of alternating metal and dielectric. We can model this material as a homogeneous effective medium with anisotropic dielectric permittivity.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer
Molecular Oncology, EarlyView.PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Journal of Materials Research and TechnologyRecently, the retained austenite (RA) with chemically heterogeneous has attracted great attention in medium Mn steel. In this work, we designed a two-step intercritical annealing (TIA) heat treatment process to prepare high-strength medium Mn steel with ...

Primordial Non-Gaussianity and Reionization
, 2013 The statistical properties of the primordial perturbations contain clues about the origins of those fluctuations. Although the Planck collaboration has recently obtained tight constraints on primordial non-gaussianity from cosmic microwave background ...

Effect of warm to hot rolling on microstructure, texture and mechanical properties of an advanced medium-Mn Steel [PDF]
, 2019 The deformation microstructures and mechanical properties were studied in a medium-Mn austenitic steel subjected to warm-to-hot ...

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Short-term effects of Mn2+ on elongation growth and H+ -extrusion in Zea mays L. coleoptile segments
Acta Societatis Botanicorum Poloniae, 2014 The effect of 10-2-10-6 M Mn+2 on the growth and acidification of the incubation medium by Zea mays L. coleoptile segments was studied. It is shown that 10-5M manganese stimulated growth (in comparison to a control without Mn+2) while concentrations from
