Investigation of Macroporous Calcium Phosphate Cement Obtained by Foamed Gelatin Polymer

This study deals with the effect of gelatin on physical and mechanical properties of  calcium phosphate bone cements. The mixture of tetracalcium phosphate (TTCP) and dicalcium phosphate (DCPA) as the cement powder was mixed with 6 wt% Na2HPO4 solution containing different amount (0, 2, 5 and 8% in w/w) of foamed gelatin as liquid phase. The physical properties were determined in the terms of s...

Activation of a plant invertase by inorganic phosphate.

Activation by orthophosphate of a plant invertase from root nodules of Lupinus luteus L. has been demonstrated. The activation affects an increase in maximum velocity (V(max)) of the reaction. Activation was also achieved with a number of similar anions and it has been possible to infer a broad classification of anions capable of serving as activators. The possibility of orthophosphate activati...

Inorganic Polymer Matrix Composite Strength Related to Interface Condition

Resin transfer molding of an inorganic polymer binder was successfully demonstrated in the preparation of ceramic fiber reinforced engine exhaust valves. Unfortunately, in the preliminary processing trials, the resulting composite valves were too brittle for in-engine evaluation. To address this limited toughness, the effectiveness of a modified fiber-matrix interface is investigated through th...

Inorganic Phosphate Accumulation by Corn Mitochondria'

Swnmary. An investigation has been made of the possibility of tutilizing the potential energy of the contracted state of corn mitochondria to drive Ca + inorganic phosphate accumulation. Contraction was obtained with succinate or NADH oxidation. In the succinate experiments the mitochondria were contracted in buffered KCl layered over sucrose in centrifuge tubes and centrifuged down through dis...

Phosphorylation by inorganic phosphate of sarcoplasmic membranes.

The calcium transport protein of the sarcoplasmic reticulum accepts inorganic phosphate rapidly when phosphorylation is initiated either by the addition of phosphate or magnesium ions to the calcium free protein. Phosphorylation proceeds much more slowly when it is initiated by the addition of the calcium chelatro ethyleneglycol-bis (beta-aminoethyl ether)-N,N'-tetraacetic acid (EGTA) to the ph...
