Nutrient imbalances in China with the focus on N and P in agricultural systems in Jiangsu Province [PDF]

open access: yes, 2004
During recent decades, the use of mineral fertilisers, especially nitrogen (N), has increased significantly in China compared with the use of organic fertilisers, such as crop residues and human, animal and green manure.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Biogas nutrient management in organic cropping - not only a nitrogen issue [PDF]

open access: yes, 2013
Nutrient imbalance, mainly due to low K and high Ca and/or Mg concentrations, was a plausible explanation for low growth response to digestate fertilisation by beetroot following harvested grass-clover biogas ley.

Nitrogen in the Environment: Sources, Problems, and Management

open access: yesThe Scientific World Journal, 2001
Nitrogen (N) is applied worldwide to produce food. It is in the atmosphere, soil, and water and is essential to all life. N for agriculture includes fertilizer, biologically fixed, manure, recycled crop residue, and soil-mineralized N.

Nitrogen and Phosphorus Balances Vary at the Whole-Farm, Field, and Within-Field Scales

open access: yesFrontiers in Sustainability, 2021
A field nutrient balance (supplied minus harvested) can be an effective, end-of-season management evaluation tool. However, development of guidance for balance-based management requires knowledge of variability in balance inputs.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

The Improvement Effects of Intercropping Systems on Saline-Alkali Soils and Their Impact on Microbial Communities

open access: yesMicroorganisms
Saline-alkali soil has poor fertility and low organic matter content, which are key factors that limit agricultural productivity. Intercropping systems can enhance biodiversity in farmlands, thereby increasing the organic matter content.

Global patterns of soil organic carbon distribution in the 20–100 cm soil profile for different ecosystems: a global meta-analysis [PDF]

open access: yesEarth System Science Data
Determining the distribution of soil organic carbon (SOC) in subsoil (20–100 cm depth) is important with respect to the global C cycle and warming mitigation.

Nutrients and Muscle Disease [PDF]

open access: yesBioMed Research International, 2015
Myopathies, classified as either hereditary or acquired, lead to common, clinically relevant complaints including fatigue, progressive strength loss, myalgias, and cramps. Important progress has been made in the comprehension of the molecular mechanisms underlying muscle diseases but, in the majority of cases, their clinical management is symptom ...
