From a population of 20 healthy male volunteers, half performed constant speed, incremental load maximal aerobic capacity (VO2max) tests on a motor-driven treadmill, while the other half performed similar VO2max tests on a bicycle ergometer. The two groups, matched for size and age, showed no significant differences in VO2max, maximum heart rate, or in post-exercise (4 min ) peripheral venous blood concentrations of lactete or pyruvate. However, post-exercise peripheral venous blood ammonia levels were significantly higher in the group tested on the bicycle ergometer than in the treadmill group. 相似文献

Stems of bioenergy sorghum (Sorghum bicolor L. Moench.), a drought-tolerant C4 grass, contain up to 50 nodes and internodes of varying length that span 4–5 m and account for approximately 84% of harvested biomass. Stem internode growth impacts plant height and biomass accumulation and is regulated by brassinosteroid signaling, auxin transport, and gibberellin biosynthesis. In addition, an AGCVIII kinase (Dw2) regulates sorghum stem internode growth, but the underlying mechanism and signaling network are unknown. Here we provide evidence that mutation of Dw2 reduces cell proliferation in internode intercalary meristems, inhibits endocytosis, and alters the distribution of heteroxylan and mixed linkage glucan in cell walls. Phosphoproteomic analysis showed that Dw2 signaling influences the phosphorylation of proteins involved in lipid signaling (PLDδ), endomembrane trafficking, hormone, light, and receptor signaling, and photosynthesis. Together, our results show that Dw2 modulates endomembrane function and cell division during sorghum internode growth, providing insight into the regulation of monocot stem development. 相似文献

Since 1984, Anopheles (Kerteszia) lepidotus has been considered a
mosquito species that is involved in the transmission of malaria in Colombia, after
having been incriminated as such with epidemiological evidence from a malaria
outbreak in Cunday-Villarrica, Tolima. Subsequent morphological analyses of females
captured in the same place and at the time of the outbreak showed that the species
responsible for the transmission was not An. lepidotus, but rather
Anopheles pholidotus. However, the associated morphological
stages and DNA sequences of An. pholidotus from the foci of
Cunday-Villarrica had not been analysed. Using samples that were caught recently from
the outbreak region, the purpose of this study was to provide updated and additional
information by analysing the morphology of female mosquitoes, the genitalia of male
mosquitoes and fourth instar larvae of An. pholidotus, which was
confirmed with DNA sequences of cytochrome oxidase I and rDNA internal transcribed
spacer. A total of 1,596 adult females were collected in addition to 37 larval
collections in bromeliads. Furthermore, 141 adult females, which were captured from
the same area in the years 1981-1982, were analysed morphologically. Ninety-five DNA
sequences were analysed for this study. Morphological and molecular analyses showed
that the species present in this region corresponds to An.
pholidotus. Given the absence of An. lepidotus, even in
recent years, we consider that the species of mosquitoes that was previously
incriminated as the malaria vector during the outbreak was indeed An.
pholidotus, thus ending the controversy. 相似文献

Multiple peripalpebral folds were the cause of severe bilateral blepharospasm and epiphora in a male Macaca fascicularis. The inner-most fold resulted in entropion and irritative keratitis. The condition was corrected surgically. 相似文献
