Dietary restriction without malnutrition prolongs life and has a beneficial effect on age-related diseases and metabolic derangements. To test the effect of food restriction on ethane production rate, ethane exhalation was measured in rats with partial food restriction. Ethane production rate in room air in rats fed 60% of food consumed by ad libitum-fed animals for 2 wk was significantly reduced (3.50 +/- 0.25 vs. 5.21 +/- 0.34 pmol.min-1.100 g body wt-1, P less than 0.01). In 100% oxygen, ethane production in food-restricted rats was not different from that of ad libitum-fed rats (21.81 +/- 1.25 vs. 19.57 +/- 1.89 pmol.min-1.100 g-1). Fifteen hours of fasting compared with ad libitum feeding reduced ethane production modestly in room air (4.37 +/- 0.45 vs. 5.21 +/- 0.34 pmol.min-1.100 g-1) and more significantly in 100% oxygen (12.37 +/- 0.78 vs. 19.57 +/- 1.89 pmol.min-1.100 g-1). Thus, in 100% oxygen, 15 h of fasting, compared with ad libitum feeding, resulted in an approximately 40% decrease in ethane production rate. It is concluded that short-term food restriction significantly reduces ethane exhalation rate in rats when measured in room air. 相似文献

Visceral leishmaniasis (VL) has been endemic in northern Tunisia and has occurred sporadically in the center of Tunisia. Recently, there have been several cases from areas known to be free of VL. We report in this work all human and canine cases of VL recorded between 2003 and 2011 and an entomological study of phlebotomine fauna in a previously non‐endemic region. Sixty‐three cases of VL were diagnosed and identified as L. infantum using several different methods. Eight species of 179 sand flies were caught and identified by both morphological and molecular methods. Two genera were present, Phlebotomus and Sergentomya, with an abundance of the subgenus Phlebotomus (Larrousius) spp., a classic vector of VL in Tunisia. Moreover, Leishmania DNA was detected in seven unfed Phlebotomus pernicousus and L. infantum was identified in three of them. This result confirms the establishment of a transmission cycle of VL in the studied region by the coexistence of infected vectors with infected hosts. 相似文献

The taxonomy and phylogeny of Hyrcanian Alnus (eight taxa) were investigated using sequence data from the nuclear ribosomal ITS and the chloroplast trnH-psbA intergenic spacer. The mean nucleotide compositions of the ITS region were completely equal for two main Hyrcanian taxa, and the ITS1 region had fewer variable sites than the ITS2 region. Two relatively distinct types of ITS2 were identified for two main clades of Hyrcanian Alnus, the A. subcoradata complex and A. glutinosa. Two recently described species, A. dolichocarpa and A. djavanshirii, did not show any diagnostic sites and had a similar pattern with A. subcordata. Three recognized subspecies of A. glutinosa were distributed in the A. incana complex. In the analysis of trnH-psbA sequence data, the three subgenera of Alnus were poorly resolved relative to one another. Alnus glutinosa had minimal sequence divergence from A. incana and A. tenuifolia, and A. subcordata had a minimum distance from A. cordata and A. orientalis. A maximum pairwise distance also was observed between Hyrcanian species (A. glutinosa and A. subcordata) with A. pendula and A. sieboldiana, respectively. Ultimately, the molecular phylogeny of Alnus based on two DNA barcode markers was not congruent with recent morphological classifications, so additional DNA markers should be explored for identifying Alder taxa in the Hyrcanian forest. 相似文献
