Nitrogen Interactions with Phosphorus and Potassium for Optimum Crop Yield, Nitrogen Use Effectiveness, and Environmental Stewardship

open access: yesThe Scientific World Journal, 2001
The development of best management practices (BMPs) for optimum nitrogen (N) use by crops contributes to farm profitability, increased food and fiber production, and best stewardship of the environment and its resources. Such BMPs are both site- and crop-

Seepage and stability analysis of pore air pressure on a high-bench dump under heavy rainfall

open access: yes工程科学学报, 2021
Under heavy rainfall, the pore air pressure in the unsaturated zone of a dump hinders rainwater infiltration in loose soil, which further affects the safety and stability of the dump.

Acclimation responses of Arabidopsis thaliana to sustained phosphite treatments [PDF]

open access: yes, 2013
Phosphite () induces a range of physiological and developmental responses in plants by disturbing the homeostasis of the macronutrient phosphate. Because of its close structural resemblance to phosphate, phosphite impairs the sensing, membrane transport,

Phosphomannosyl receptors may participate in the adhesive interaction between lymphocytes and high endothelial venules. [PDF]

open access: yes, 1984
Normal and malignant lymphocytes can migrate from the bloodstream into lymph nodes and Peyer's patches. This process helps distribute normal lymphocytes throughout the lymphoid system and may provide a portal of entry for circulating malignant cells.

Development of Enthesopathies and Joint Structural Damage in a Murine Model of X-Linked Hypophosphatemia

open access: yesFrontiers in Cell and Developmental Biology, 2020
X-linked hypophosphatemia (XLH) is characterized by rickets and osteomalacia, caused by inactivating mutations in the Phosphate-regulating endopeptidase homolog X-linked (PHEX) gene.

The Aryne Phosphate Reaction** [PDF]

open access: yesAngewandte Chemie, 2021
AbstractCondensed phosphates are a critically important class of molecules in biochemistry. Non‐natural analogues are important for various applications, such as single‐molecule real‐time DNA sequencing. Often, such analogues contain more than three phosphate units in their oligophosphate chain.
