Motoji Sawabe and Akihiko Hamamatsu equally contributed to this work.Aim: Aortic dilatation is a well-known phenomenon in the elderly. We therefore aimed to study the pathobiological determinants of aortic dilatation. Methods: Retrospective chart review. The subjects were 833 consecutive autopsy cases (616 men and 217 women) of community deaths. The age at death ranged from 20 to 94 years, with an average of 59.2 years. We measured the internal circumference of the aortic root, arch, descending portion, abdominal portion, and bifurcation in unfixed opened aorta at the time of autopsy. Results: The simple correlation between age and aortic circumference was strongest for the descending portion, followed by the arch, abdominal portion, root, and bifurcation. The simple correlation coefficient reached 0.836 for the descending portion ( p 0.001). The circumference of the descending portion increased significantly as the severity of aortic atherosclerosis increased ( p for trend 0.001). Multiple regression analysis showed that age, sex, and body height were significantly correlated with the aortic circumference at all five measurement sites, while severe atherosclerosis was correlated with the aortic circumference at the root, and descending and abdominal portions. Six contributing factors (age, sex, body height, smoking history, hypertension, and severe atherosclerosis) explained 68.5% of the variance in circumference in the descending portion; age explained 57.5%; sex 8.4%; body height 1%; and severe atherosclerosis 0.8%. Conclusion: The contribution of atherosclerosis to aortic dilation was very weak, representing less than one seventieth of the contribution of age. The aortic circumference, especially in the descending portion, serves as an excellent age-related marker. J Atheroscler Thromb, 2011; 18:157-165.

“…Body surface area was calculated from height and mass using the method of Fujimoto and Watanabe (13), and body fatness was assessed as the mean value of the skinfold thickness measured with skinfold calipers over the chest, flank, back, triceps, front of the forearm and thigh, and back of the lower leg. The V O2 max for each subject was estimated in a submaximal step-load bicycle exercise test performed on a day other than those of the exercise tests.…”

. Effects of menstrual cycle and physical training on heat loss responses during dynamic exercise at moderate intensity in a temperate environment. Am J Physiol Regul Integr Comp Physiol 288: R1347-R1353, 2005. First published January 27, 2005 doi:10.1152/ajpregu.00547.2004.-We evaluated the effects of the menstrual cycle and physical training on heat loss (sweating and cutaneous vasodilation) responses during moderate exercise in a temperate environment. Ten untrained (group U) and seven endurance-trained (group T) women (maximal O2 uptake of 36.7 Ϯ 1.1 vs. 49.4 Ϯ 1.7 ml ⅐ kg Ϫ1 ⅐ min Ϫ1 , respectively; P Ͻ 0.05) performed a cycling exercise at 50% maximal O 2 uptake for 30 min during both the midfollicular and midluteal menstrual phase in a temperate environment (ambient temperature of 25°C, relative humidity of 45%). In group U, plasma levels of estrone, estradiol, and progesterone at rest and esophageal temperature (Tes) during exercise were significantly higher during the midluteal than during the midfollicular phase (P Ͻ 0.05). Sweating rate and cutaneous blood flow (measured via laserDoppler flowmetry) on the chest, back, forearm, and thigh were lower during the midluteal than during the midfollicular phase during exercise. Tes threshold for heat loss responses was significantly higher and sensitivity of the heat loss responses was significantly lower in the midluteal than in the midfollicular phase, regardless of body site. These effects of the menstrual cycle in group U were not observed in group T. The sweating rate and cutaneous blood flow were significantly higher in group T than in group U, regardless of menstrual phase or body site. Tes threshold for heat loss responses was significantly lower and sensitivity of heat loss responses was significantly greater in group T than in group U in the midluteal phase; however, sensitivity of the sweating response was significantly greater in the midfollicular phase. These results suggest that heat loss responses in group U were inhibited in the midluteal phase compared with in the midfollicular phase. Menstrual cycle had no remarkable effects in group T. Physical training improved heat loss responses, which was more marked in the midluteal than in the midfollicular phase. thermoregulation; estradiol; progesterone; long-term endurance training; heat acclimatization HEAT LOSS RESPONSES, SUCH as sweating and cutaneous vasodilation, during exercise in women differ from those in men because female hormones modify the responses after puberty (3). All studies of the effects of the menstrual cycle on heat loss responses during exercise have demonstrated that the core body temperature thresholds for sweating and cutaneous vasodilation are higher during the luteal phase of the menstrual cycle than during the follicular phase (14,15,17,18,23,31,33,35). In addition, the rise in the core body temperature threshold for sweating and cutaneous vasodilation during the luteal phase is mainly due to elevated progesterone concentrations (8, 31).Conversely, there are conflictin...
