41.   We cannot exclude the possibility, however, that other unknown mechanisms may be involved in the effects observed in this study.

42.   There are several mechanisms for bicarbonate transport across placma membranes.

43.   It is not clear to what extent these mechanisms are operative in vivo, where extracellular fluid osmolality is usually regulated within a narrow range.

44.   The, the mechanisms of defence are a concept which overlaps, and to some extent replaces, repression.

45.   Brennan picks up on the idea that revolution mechanism is a strong possibility in a society with large income disparities.

46.   Chronic dietary insufficiency is thought to be the single main cause but the mechanism is unclear.

47.   These mechanisms were not able to offset the net sodium secretion induced by CT, however, which occurred despite net water absorption.

48.   Other mechanisms may also be at work.

49.   The mechanism is unknown, although it has been suggested that activation of tumour necrosis factor may be responsible.

50.   In most cases the mechanism of death is ventricular fibrillation occurring in the setting of coronary artery disease.
