argument. Clinical experience of the blood bank in 9000 cases was uniformly favourable. The way is open to replace citrate, at least partially, by lactate. This could be done either maintaining the dilution as we personally prefer, or preparing a more concentrated formula, if dilution is not considered an advantage. A specific action of lactate was not found, but lactate is a good preservative ...

This study examines the impact of bacterial concrete on strength and self-healing. Bacterial has better compressive strength, permeability, corrosion resistance, chemical precursors, alkalinity mechanical stress. Bacillus subtilis calcium lactate spore powder effects are explored in this study, influence form self-healing capacity to crack repair. The concentration 105 cells/mL is used with 0.3...

Retro-aldol reactions have been implicated as the limiting steps in catalytic routes to convert biomass-derived hexoses and pentoses into valuable C2, C3, and C4 products such as glycolic acid, lactic acid, 2-hydroxy-3-butenoic acid, 2,4-dihydroxybutanoic acid, and alkyl esters thereof. Due to a lack of efficient retro-aldol catalysts, most previous investigations of catalytic pathways involvin...

In experiments employing hydrogen isotopes as tracers the possibility of relatively large isotope effects may be anticipated. In the main, this is because of the difference in zero-point energy between a bond to deuterium or tritium and the corresponding bond to hydrogen. When a hydrogen isotope effect is encountered in a rate process the result may be interpreted as evidence that the breaking ...

After coronary artery bypass graft (CABG), mesenteric ischemia is a rare but dreadful complication with high mortality rates. Prophylactic use of intra-aortic balloon pump (IABP) is a common practice in patients with severe coronary artery disease awaiting CABG. During withdrawal of the IABP, there is a risk of dislodging atheromatous debris, thus causing peripheral and mesenteric emboli, which...
