Molecular Engineering Mediated Interfacial Assembly as an Artificial Extracellular Matrix Remolds Bacteria With Enhanced Abiotic Resilience

Advanced Science, EarlyView.
A biomimetic artificial extracellular matrix is assembled directly on Pseudomonas fluorescens by co‐assembling amyloid‐like lysozyme and alginate at the cell surface. This conformal nanocoating acts as both a hydration buffer and a physiological priming layer, markedly enhancing desiccation tolerance, seed adhesion, storage stability, and biocontrol ...

Downsizing the Histone H3–H4 Quaternary Structure Into Foldamer Mimetics Yields High‐Affinity and Cell‐Permeable Ligands of ASF1

Angewandte Chemie, EarlyView.
We present a foldamer strategy to downsize the histone H3‐H4 quaternary structure into high‐affinity, medium‐sized binders (∼2 kDa) for the histone chaperone ASF1. Our peptide‐oligourea chimeras, designed through structure‐guided optimization and foldamer chemistry, recapitulate the natural H3‐H4 dimer binding mode while demonstrating plasma stability ...

Nanopore‐Based Protein Deceleration and Sensing Using Graphene/Si3N4 Dual Membrane Cavity

Advanced Science, EarlyView.
A graphene/Si3N4 dual membrane cavity system achieves multi‐stage protein deceleration through spatial geometry. Multi‐level current traces provide high‐resolution spatial localization and early warning signals. ABSTRACT Sequencing of protein with nanopores has emerged as a powerful tool offering rapid readout, high accuracy, low cost, and portability.

Pectin methylesterase activity determined by different methods and thermal inactivation of exogenous pme in mango juice Determinação da atividade da pectina metilesterase por diferentes métodos e inativação térmica da PME exógena no suco de manga

Ciência e Agrotecnologia, 2011
Pectin methylesterase (PME) hydrolyzes methyl ester groups in pectin chains to form carboxylic groups, releasing methanol and H3O+. The aim of this study was to determine PME activity in samples of pectinases by UV-VIS spectroscopy, to measure the acid ...

“Something’s Happening Here!”: Popular Music Education in the United States [PDF]

IASPM Journal, 2015
Although the number of opportunities to learn popular music in the United States continues to grow, popular music education (PME) programs remain exceptional at primary, secondary, and tertiary levels of institutionalized music education.

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Computation‐Guided Tunnel Engineering Enhances O2 Transport and H2O2 Resistance of Fe(II)/α‐Ketoglutarate‐Dependent Dioxygenases

Advanced Science, EarlyView.
This study presents a computational tunnel engineering strategy in Fe(II)/α‐ketoglutarate‐dependent dioxygenases (αKGDs) to enhance oxygen (O2) transport, an essential molecule for αKGDs, and limit hydrogen peroxide (H2O2) entry, an inhibitor from the αKG supply system.

La réalité de l’innovation dans les PME Algériennes

Revue Marocaine de Recherche en Management et Marketing, 2014
La problématique de la relation entre l’innovation et de la compétitivité fait l’objet d’une abondante littérature car elle s’inscrit de façon permanente dans la vie des organisations (Rothwell et Dodgson, 1994 et Cohen, 1995).Néanmoins, en Algérie cette

Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis

Advanced Science, EarlyView.
This study uncovers a previously unrecognized copper‐COMMD1‐SOD1 regulatory axis, revealing that pathological copper overload paradoxically suppresses SOD1 activity by promoting COMMD1‐dependent disruption of SOD1 homodimerization. These findings redefine the regulatory role of copper in SOD1 biology and provide novel mechanistic insight into the ...
