Metabolic Responses to Excess Manganese in Legumes: Variations in Nitrogen Compounds in Canavalia ensiformis (L.) DC and Cajanus cajan (L.) Millsp

open access: yesLegume Science
Manganese (Mn) is crucial as a trace element for plant metabolism, but high concentrations in soil can induce symptoms of toxicity. This study aimed to evaluate the metabolism of nitrogen compounds and biomass production in Canavalia ensiformis and ...

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Integrative analyses of genetic variation in enzyme activities of primary carbohydrate metabolism reveal distinct modes of regulation in Arabidopsis thaliana [PDF]

open access: yes, 2008
Background Plant primary carbohydrate metabolism is complex and flexible, and is regulated at many levels. Changes of transcript levels do not always lead to changes in enzyme activities, and these do not always affect metabolite levels and fluxes.

Genetically Programmed Shape‐Morphing of Engineered Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Protein‐Nanoarchitectures for Low‐Field Intracellular Electro‐Immunomodulation

open access: yesAdvanced Functional Materials, EarlyView.
DHQ‐SDH‐mediated binding of AuNPs drives the formation of interconnected, chain‐like nanoarchitectures with enhanced electrical conductivity. These conductive assemblies undergo macrophage uptake and enable low‐field electrical stimulation, promoting M1‐to‐M2 phenotypic switching with decreased iNOS and increased CD206 expression. Such protein‐mediated

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

open access: yesAdvanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Unique Role of Microstructure of a Bioimplant Zinc Alloy and Protein Content of Simulated Body Fluid in Corrosion and Fracture

open access: yesAdvanced Functional Materials, EarlyView.
BSA addition to physiological solutions enhances resistance of a Zn alloy to stress corrosion cracking (SCC) but reduces its corrosion resistance. Extended surface characterization explains the contrasting influences on corrosion and SCC. Unexpectedly, the alloy suffers transgranular SCC (TGSCC), despite extensive grain boundary precipitation. Thorough
