Physical exercise, aortic blood pressure, and aortic wall elasticity and composition in rats.
With a training schedule (8 weeks' treadmill running at 30 m/min up a 10% incline 5 d/wk for 90 min/day), we investigated whether exercise modifies aortic wall dimensions, composition (calcium and elastin content), or stiffness in normotensive 6-month-old male Wistar WAG/Rij rats. Maximal oxygen uptake was measured in half of the rats (n=10 per group). Wall stiffness was evaluated in the other ...
متن کاملThe Greenland shark: a new challenge
21 The free radical theory of ageing predicts that long-lived species should be more 22 resistant to oxidative damage than short-lived species. Although many studies support 23 this theory, recent studies found notable exceptions that challenge the generality of this 24 theory. In this study, we have analysed the oxidative status of the Greenland shark 25 (Somniosus microcephalus), which has re...
متن کاملBlood pressure in the newborn estimated by the flush method.
The increasingly widespread practice of careful routine examination of the newborn infant, particularly where it reveals a cardiac murmur, has increased the need for a simple method of measuring neonatal blood pressure. As assessed indirectly, widely varying blood pressures have been recorded in the newborn. Sphygmomanometric estimation by the standard methods of auscultation and palpation is n...

متن کاملThe Greenland shark Somniosus microcephalus—Hemoglobins and ligand-binding properties
A large amount of data is currently available on the adaptive mechanisms of polar bony fish hemoglobins, but structural information on those of cartilaginous species is scarce. This study presents the first characterisation of the hemoglobin system of one of the longest-living vertebrate species (392 ± 120 years), the Arctic shark Somniosus microcephalus. Three major hemoglobins are found in it...
