Rate of 14CO2 production from variously labeled forms of [14C]glucose in human breast invasive ductal carcinoma tissues.

To establish possible cancerous aggressiveness between the metabolism of variously labeled [14C]glucose in the human breast invasive ductal carcinoma (IDC) tissues, we measured the rates of 14CO2 production from those tissues by using radiorespirometry, expressing the results as initial velocity (V) in nanomoles of 14CO2 min-1 g-1 of fresh tissues. The Vc data were compared with results of the SBR system, which grades up from I to III. Vc,1 values measured with [1-14C]glucose increased from 1.

A proposed estimate of the tumor aggressiveness of human breast cancer using radiorespirometry.

The relationships between carcinomatous aggressiveness and the glucolytic metabolism, namely the rate of 14CO2 production from [U-14C] glucose, are obtained from human breast tissues using radiorespirometry. The values are estimated as the initial velocity (V) expressed in eta 14CO2 x min-1 x g-1 of fresh tissues by [U-14C] glucose metabolism. The aggressiveness of the breast carcinomatous is diagnosed by the SBR grade system.

[A comparative mechanical study of types of external fixator (author's transl)].

The authors have designed and original type of external fixator which can be used in the forces in case of armed conflict. Study has been directed towards a simple, strong and inexpensive apparatus which can be applied in emergency circumstances. Secondarily it can be replaced by another apparatus to allow compression, distraction or better reduction of a fracture without removal of the pins.
