Phosphate Sensing [PDF]

open access: yesAdvances in Chronic Kidney Disease, 2011
Human phosphate homeostasis is regulated at the level of intestinal absorption of phosphate from the diet, release of phosphate through bone resorption, and renal phosphate excretion, and involves the actions of parathyroid hormone, 1,25-dihydroxy-vitamin D, and fibroblast growth factor 23 to maintain circulating phosphate levels within a narrow normal

Serum phosphate is not an early predictor of neurocognitive outcomes in acute carbon monoxide poisoning patients [PDF]

open access: yesClinical and Experimental Emergency Medicine, 2023
Objective Carbon monoxide (CO) poisoning causes brain injury by hypoxia and inflammatory mechanisms. Hypoxic conditions result in increased serum phosphate concentration due to loss of polarity of the cell membrane, changes in membrane fluidity, and ...

Osteoclast differentiation from human blood precursors on biomimetic calcium-phosphate substrates [PDF]

open access: yes, 2017
The design of synthetic bone grafts to foster bone formation is a challenge in regenerative medicine. Understanding the interaction of bone substitutes with osteoclasts is essential, since osteoclasts not only drive a timely resorption of the biomaterial,
