In order to provide this support, instructors would have to: (1) to disc...

The in£uence of wind patterns on behaviour and e¡ort of free-ranging male wandering albatrosses (Diomedea exulans) was studied with miniaturized external heart-rate recorders in conjunction with satellite transmitters and activity recorders. Heart rate was used as an instantaneous index of energy expenditure. When cruising with favourable tail or side winds, wandering albatrosses can achieve hi...

The clinical course of a patient with peripartum cardiomyopathy and hyperprolactinaemia is described. Hyperprolactinaemia may be a factor in this patient's heart failure.

Episodes of disordered behavior, coma or convulsions are not infrequent during the course of severe, chronic, congestive heart failure. When observed, they are usually attributed to some process such as anoxemia, a cerebral vascular disturbance, drug intoxication, electrolyte imbalance, or some other alteration directly or indirectly related to the underlying cardiac disorder. The importance of...
