Root‐zone enrichment of particulate and nonparticulate organic carbon and nitrogen under grassland management and woodlands across a soil texture gradient in North Carolina, USA

Grassland Research
Background Surface‐soil organic matter accumulation is expected under well‐managed grasslands. Characterizing particulate and nonparticulate organic C and N fractions across a soil texture gradient under different conservation land management systems ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Unveiling the mechanism secret of abrasion emissions of particulate matter and microplastics

Scientific Reports
Recent research highlights that non-exhaust emissions from the abrasion of tires and other organic materials have emerged as a substantial source of airborne particulate matter and marine microplastics.

Chemical composition modulates the adverse effects of particles on the mucociliary epithelium

Clinics, 2015
OBJECTIVE:We compared the adverse effects of two types of real ambient particles; i.e., total suspended particles from an electrostatic precipitator of a steel mill and fine air particles from an urban ambient particulate matter of 2.5 µm, on mucociliary

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Biodegradability of dissolved organic carbon in permafrost soils and aquatic systems: A meta-analysis [PDF]

, 2015
As Arctic regions warm and frozen soils thaw, the large organic carbon pool stored in permafrost becomes increasingly vulnerable to decomposition or transport.
