Sialic Acid Sensing via Molecularly Imprinted Polymer on Laser‐Induced Graphene

Advanced Sensor Research, EarlyView.
Sialic acid is an important biomarker for oral and overall health. Salivary levels of sialic acid are linked with oral cancer and other diseases. We develop a point‐of‐care sensor for sialic acid, based on molecularly imprinted aminophenylboronic acid electropolymerized onto laser‐induced graphene.

Plant-root-litter-soil C, N, P stoichiometry and plant phosphorus accumulation and utilization response to warming and phosphorus input in desert steppe

Global Ecology and Conservation
Nutrient cycling in desert steppe can be affected by continuous climate warming and exogenous nutrient inputs. This would alter plant nutrient uptake and utilization, affecting the plant production and service functions of desert ecosystems.

ROS Activated NETosis of Bone Marrow CD55+ Intermediate Mature Neutrophils Through HIF1α‐PADI4 Pathway to Initiate Bone Aging

Advanced Science, EarlyView.
In this study, we find CD55+ neutrophils show activated NETosis within bone marrow, induce BMSC senescence and osteogenesis inhibition, finally leading to bone aging initiation. Mechanistically, ROS synergizes with the CD55‐driven HIF1α‐PADI4 pathway to promote NETosis.

The Influence of Asset and Access Poverty on Crop Production and Land Degradation in Uganda [PDF]

This study investigated the linkages between poverty, agricultural productivity and land degradation in Uganda. Results show that farmers in the study region of Uganda deplete about 1.2% of the nutrient stock stored in the topsoil per year, leading to a ...

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

Advanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Soil Erosion as an Environmental Concern in Vineyards: The Case Study of Celler del Roure, Eastern Spain, by Means of Rainfall Simulation Experiments

Beverages, 2018
Soil erosion in vineyards is considered as an environmental concern as it depletes soil fertility and causes damage in the fields and downstream. High soil and water losses decrease soil quality, and subsequently, this can reduce the quality of the ...
