Implantable Multifunctional Micro‐Oxygen Reservoir System for Promoting Vascular‐Osteogenesis via Remodeling Regenerative Microenvironment

open access: yesAdvanced Science
AbstractHypoxia and reactive oxygen species (ROS) overaccumulation cause persistent oxidative stress and impair intrinsic regenerative potential upon tissue injury. For local tissue injury with hypoxia, such as bone fracture and defects, a localized‐sufficient oxygen supply is highly desirable but remains challenging.

Local and Systemic Micro-Rheological Changes during Intestinal Anastomosis Operation: A Metabolic Dependence in an Experimental Model

open access: yesMetabolites
Hemorheological factors may show arterio-venous differences. Alterations in acid-base and metabolic parameters may also influence these factors. However, little is known about changes in micro-rheological parameters during abdominal surgery, influencing ...

Emerging Trends in Organic Photoreactions Utilizing Disulfides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Methanogen‐Mediated Precipitation of Mn Carbonates at the Expense of Mn Oxides

open access: yesGeophysical Research Letters
Whether Mn carbonates can be used as a proxy for the oxygenation event is debated. Here we examined the Early Cretaceous lacustrine Mn carbonates from North China, which contain abundant microbial fossils. The extremely positive δ13C (up to +15‰ relative

Graphene oxide/exfoliated black phosphorus van der Waals heterojunctions for PEDOT:PSS‐free‐based organic light‐emitting diodes achieving excellent electroluminescence performance

open access: yesFlexMat, EarlyView.
A novel two‐dimensional heterojunction assembled from graphene oxide and exfoliated black phosphorus via van der Waals interactions is proposed to replace widely used poly(3,4‐ethylenedioxythiophene)‐polystyrene sulfonate for efficient hole injection layer in organic light‐emitting diodes, achieving impressive electroluminescence performance.

Probiotic consumption reduces alveolar bone loss and kidney damage in pregnant rats with experimental periodontitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Bifidobacterium animalis subsp. lactis HN019 (B. lactis HN019) is a probiotic bacterial strain with immunomodulatory properties. Its benefits have been observed in healthy and systemically compromised animals with periodontitis (PD). Our objective was to investigate the local and systemic effects of the systemic administration of B.

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.
