Porous Solids of Boron Phosphate, Aluminum Phosphate, and Silicon Phosphate

MRS Proceedings, 1994
AbstractAnhydrous sol-gel condensation of triethyl phosphate [(CH3CH2O)3PO] with boron trichioride (BCl3), triethyl aluminum [(CH3CH2)3Al] or silicon tetrachloride [SiCI4] in organic solvents led to rigid gels. The pore fluid of the gels was removed under supercritical conditions in a pressurized vessel to form porous solids. The condensation chemistry

Deep-ultraviolet transparent phosphates RbBa2(PO3)5 and Rb2Ba3(P2O7)2 show nonlinear optical activity from condensation of [PO4](3-) units.

Journal of the American Chemical Society, 2014
It is challenging to explore deep-ultraviolet (deep-UV) nonlinear optical (NLO) materials that can achieve a subtle balance between deep-UV transparency and high NLO activity.

Phosphate Homeostasis and Disorders of Phosphate Metabolism

Current Pediatric Reviews
Abstract: Phosphate is indispensable for human life and evolutionary changes over several millions of years have established tightly regulated mechanisms to ensure phosphate homeostasis. In this process, calcium and phosphate metabolism have come to be intricately linked together.

Calcitonin and phosphate

Molecular and Cellular Endocrinology, 1981
This report summarizes the relationship of calcitonin to phosphate. The hypocalcemic action of calcitonin is dependent upon phosphate, while the hypophosphatemic action is independent of calcium. Calcitonin moves phosphate into bone cells and bone fluid in contrast to reducing the movement of calcium from bone to blood.

Glycogen, glycolytic intermediates and high-energy phosphates determined in biopsy samples of musculus quadriceps femoris of man at rest. Methods and variance of values.

Scandinavian Journal of Clinical and Laboratory Investigation, 1974
Methods are described for the determination of glycogen, glycolytic intermediates, and high-energy phosphates in muscle biopsy samples. Initial freezedrying of samples and extraction of metabolites with relatively weak acid are preferred.

Lipid phosphate phosphatases and lipid phosphate signalling

Biochemical Society Transactions, 2005
Mammalian LPPs (lipid phosphate phosphatases) are integral membrane proteins that belong to a superfamily of lipid phosphatases/phosphotransferases. They have broad substrate specificity in vitro, dephosphorylating PA (phosphatidic acid), S1P (sphingosine 1-phosphate), LPA (lysophosphatidic acid) etc.

The phosphate sensor

Biosensors and Bioelectronics, 1998
The field of phosphate sensors is reviewed. Sensors in the form of potentiometric ion-selective electrodes, amperometric and potentiometric enzyme electrodes, amperometric plant-tissue electrodes and other devices in the form of integrated probes used for determining orthophosphate concentrations in aqueous solutions, are described.
