Hyperhydration prior to moderate‐intensity exercise causes arterial hypoxaemia [PDF]

open access: yesEquine Veterinary Journal, 2002
Summary The second day of a 3‐day event is the most physically demanding of the 3 days. If this is performed under hot and humid environmental conditions, detrimental effects on cardiovascular and thermoregulatory function and, therefore, on exercise capacity, may occur due to exercise‐induced dehydration.

Special symposium: In vitro plant recalcitrance loss of plant organogenic totipotency in the course of In vitro neoplastic progression [PDF]

open access: yes, 2018
Summary: The aptitude for organogenesis from normal hormone-dependent cultures very commonly decreases as the tissues are serially subcultured. The reasons for the loss of regenerative ability may vary under different circumstances: genetic variation in ...
