Effect of prolonged, heavy exercise on pulmonary gas exchange in athletes.

Abstract: During maximal exercise, ventilation-perfusion inequality increases, especially in athletes. The mechanism remains speculative. We hypothesized that, if interstitial pulmonary edema is involved, pr...

An efficient micro-method of DNA isolation from mature leaves of four hardwood tree species Acer, Fraxinus, Prunus and Quercus

Abstract: It is difficult to purify DNA from mature tree leaves at the end of the growing season, because of their thick cell wall, and high content in polysaccharides, phenolic compounds and endonucleases. A simple, fast and efficient method for DNA purification from 100 mg fresh weight leaf samples is described here. It has been developed for extracting DNA from mature leaves of Quercus, Fraxinus Prunus and Acer. The protocol is a modified CTAB (hexadecyltrimethylammonium bromide) method including a combina- tion of β-mercaptoethanol, polyvinylpyrrolidone, sodium dodecyl sulfate and lithium chloride including short centrifugation runs. It is very efficient yielding up to 950 μg DNA/g of fresh weight, even when very mature leaves are processed. The extracted DNA was used as template to characterise oaks by microsatellite analysis. Its efficiency has been compared to four commercially available kits and two other published. CTAB protocols. The protocol is also inexpensive compared to commercial kits. (© Inra/Elsevier, Paris.)

Optimal Power Management With GHG Emissions Limitation in All-Electric Ship Power Systems Comprising Energy Storage Systems

Abstract: The extensive electrification of ship power systems has become a very appealing option for the development of more efficient and environmentally friendly ships. Optimal power management and energy storage systems will have a key role in such systems as they can lead to fuel consumption reduction and increase overall ship efficiency. However, technical difficulties arising from the inherent complexity of such systems should be overcome. In this paper, the optimal operation of a ship electric power system comprising full electric propulsion and energy storage system is analyzed. An optimal power management method is proposed so that the operation cost is minimized, greenhouse gas emissions are limited and, at the same time, the associated technical and operational constraints are not violated.
