Use of Nitrogen Isotope To Determine Fertilizer- and Soil-Derived Ammonia Volatilization in a Rice/Wheat Rotation System.

Xu Zhao et al.

Journal of agricultural and food chemistry, 64(15), 3017-3024 (2016-03-30)

The nitrogen (N) isotope method reveals that application of fertilizer N can increase crop uptake or denitrification and leaching losses of native soil N via the "added N interaction". However, there is currently little evidence of the impact of added

Severe and Regionally Widespread Increases in Tissue Urea in the Human Brain Represent a Novel Finding of Pathogenic Potential in Parkinson's Disease Dementia.

Melissa Scholefield et al.

Frontiers in molecular neuroscience, 14, 711396-711396 (2021-11-10)

Widespread elevations in brain urea have, in recent years, been reported in certain types of age-related dementia, notably Alzheimer's disease (AD) and Huntington's disease (HD). Urea increases in these diseases are substantive, and approximate in magnitude to levels present in

Selective loading and processing of prespacers for precise CRISPR adaptation.

Sungchul Kim et al.

Nature, 579(7797), 141-145 (2020-02-23)

CRISPR-Cas immunity protects prokaryotes against invading genetic elements1. It uses the highly conserved Cas1-Cas2 complex to establish inheritable memory (spacers)2-5. How Cas1-Cas2 acquires spacers from foreign DNA fragments (prespacers) and integrates them into the CRISPR locus in the correct orientation
