Enhanced Endophytic Colonization of Flavobacterium Promotes Plant Resistance to Fusarium Wilt

open access: yesAdvanced Science, EarlyView.
A natural microbial consortium employing a cross‐feeding strategy forms a stratified biofilm that promotes endophytic colonization of auxotrophic Flavobacterium. This enhanced colonization activates plant systemic resistance, effectively suppressing Fusarium wilt.

Two-dimensional apparent microfabric of the basal Late Weichselian till and associated shear zone: case study from western Latvia [PDF]

open access: yesEstonian Journal of Earth Sciences, 2008
The examination of glacial sediments in thin sections has become a common procedure in recent years. Apparent sand grain orientation (microfabric) in thin sections is one of the key elements marking certain microstructures.

Synergistic Integration of Fe–N4 Single‐Atom Sites and Directionally Aligned Electrode Architecture for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.

Study of the Urinary Ratio of 6 β-Hydroxycortisol/Cortisol as a Biomarker of CYP3A4 Activity in Egyptian Patients with Chronic Liver Diseases

open access: yesBiomarker Insights, 2006
Summary The urinary ratio of 6 β-hydroxycortisol/cortisol (6 β-OHC/C) as a biomarker of CYP3A4 metabolizing activity has been studied in Egyptian patients with chronic liver cirrhosis associated with previous hepatic Schistosomiasis infection to ...

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

open access: yesAdvanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.

Strengthening Constitutive Motifs in Isotropic Fibrous Hydrogel for Exceptional Damage Resistance

open access: yesAdvanced Science, EarlyView.
An orientation‐free strategy is reported for fabricating damage‐resistant hydrogels by strengthening constitutive motifs in isotropic fibrous (IF) networks. Through nonsolvent quenching followed by salting‐out, IF networks are generated and their multiscale constituents are subsequently reinforced, yielding dense and crystalline isotropic nanofiber ...

No-till

open access: yes, 2021
No-till can often increase soil carbon, soil quality and function, and reduce CO2 emissions when compared to conventional tilling practices. Soil microbial biomass increases (+37 percent), including both fungal (+31 percent) and bacterial biomass (+11 percent), in top 20-cm soils under no-till agro-ecosystems, but not in sandy soils.

Nascent Extracellular Matrix Converts Biomaterial Cues into Cell Fate Decisions

open access: yesAdvanced Science, EarlyView.
This study uncovers a tri‐directional interplay among cells, hydrogels, and their nascent extracellular matrix. Hydrogel norbornene modification alters CD44‐mediated cell–hydrogel interactions, which shape nascent matrix deposition, composition, and spatial organization.
