An efficient bacterial laccase-mediated system for polyurethane foam degradation

Frontiers in Microbiology
Polyurethane (PU), a segmented block copolymer with chemically resistant urethane linkages and tunable architecture, presents persistent biological recycling challenges. This study presents a Bacterial Laccase-Mediated System (BLMS) derived from Bacillus

Evaluating applicability of multi-source precipitation datasets for runoff simulation of small watersheds: a case study in the United States

European Journal of Remote Sensing, 2020
Small watersheds are ideal objects for studying the evolution of hydrological and water resources at small scales. Whether precipitation products can meet the runoff simulation of small watersheds is the main purpose of this study.

Dealing with locally-driven degradation: A quick start option under REDD+

, 2011
The paper reviews a number of challenges associated with reducing degradation and its related emissions through national approaches to REDD+ under UNFCCC policy. It proposes that in many countries, it may in the short run be easier to deal with the kinds

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

PGRP-SC–mediated innate immune memory against pathogenic bacteria in Drosophila

hLife
Trained immunity is essential for innate immune cells to retain a memory of previously encountered pathogens, strengthening the hosts’ response against these pathogens. However, the mechanisms governing trained immunity have not been well elucidated.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Intermediate Temperature Electrochemical Properties of Yb3+ Doped SrCeO3- carbonate and Chloride Composite Electrolytes

International Journal of Electrochemical Science, 2018
In this work, novel SrCe0.9Yb0.1O3-α-(Li/Na)2CO3 (SCYb-LN) and SrCe0.9Yb0.1O3-α-LiCl-SrCl2 (SCYb-LS) electrolyte composites were successfully fabricated at low temperature. The SEM image results show that the composites possess sufficient density.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.
