Downregulation of VRK1 by p53 in response to DNA damage is mediated by the autophagic pathway. [PDF]

PLoS ONE, 2011
Human VRK1 induces a stabilization and accumulation of p53 by specific phosphorylation in Thr18. This p53 accumulation is reversed by its downregulation mediated by Hdm2, requiring a dephosphorylated p53 and therefore also needs the removal of VRK1 as ...

Evaluation of IHH, PTCH1, and SMO protein immunohistochemistry in the human mandibular condyle at fetal stages from 30 to 80 mm greatest length

The Anatomical Record, EarlyView.
Abstract This study evaluated the morphogenesis of the temporomandibular joint (TMJ) in human fetuses during the third month of gestation through the analysis of immunohistochemistry for the proteins Indian Hedgehog (IHH), Patched‐1 (PTCH1), and Smoothened (SMO).

Keggin‐Type Aluminum Polyoxometalate‐Mediated Oxidation of Amorphous Carbon for Engineered Electrochemical Interfaces

Carbon Energy, EarlyView.
Keggin‐type Al‐POM‐coated silica achieves selective surface oxidation of amorphous carbon through electrostatic attraction and proton‐coupled oxidation, tailoring interfacial properties for lithium‐ion batteries and semiconductor processes. ABSTRACT Amorphous carbon is widely used in energy storage and semiconductor technologies, where surface ...

Coordination Effect of Oligopolists' Multimarket Contact

International Studies of Economics, EarlyView.
ABSTRACT In this article, we examine the coordination effect of oligopolists' multimarket contact with asymmetric cost. We extend a model of infinitely repeated multimarket contact games with “symmetric advantage” in the seminal paper of Bernheim and Whinston (The RAND Journal of Economics 1990; 21(1): 1–26).

Analysis of a Lateral Grain Boundary for Reducing Performance Variations in Poly-Si 1T-DRAM

Micromachines, 2020
A capacitorless one-transistor dynamic random-access memory device that uses a poly-silicon body (poly-Si 1T-DRAM) has been suggested to overcome the scaling limit of conventional one-transistor one-capacitor dynamic random-access memory (1T-1C DRAM).

Obtaining Curvature‐Based HLD Parameters for Single Ionic Surfactants via Small Angle X‐Ray Scattering (SAXS)

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT The hydrophilic–lipophilic difference (HLD) for ionic surfactant microemulsions (μEs) can be interpreted as the curvature normalized by the tail length parameter (L), if it is corrected by a factor “bi”, bi·HLD = HLDcurv = HLDbi = bi·ln(S) – kbi·EACN + Ccbi, with bi and kbi representing the curvature sensitivity to changes in salinity (S, g ...

Polydopamine‐Antibiotic Composite Coating for Antibiofilm Applications

Macromolecular Bioscience, EarlyView.
Antibiotic‐loaded polydopamine coatings are developed to combat biofilm‐forming bacteria on catheter surfaces. These coatings strongly inhibit Pseudomonas aeruginosa biofilm formation on diverse materials, including during continuous artificial‐urine flow, and can accommodate multiple antibiotics.

Engineering Metastability in Atomic Layer Deposition: Polymorph and Valence Control

Small, EarlyView.
This work presents strategies for stabilizing two types of metastable phases: structural polymorphs and multivalence states via ALD. These approaches focus on lowering the energy barriers required for metastable phase formation, enabling access to metastable states beyond the thermodynamic limits imposed by the low‐temperature conditions of ALD.
