    Notizen: Abstract Male-produced rectal gland secretions of a number of species now considered to be members of theBactrocera dorsalis complex of fruit flies have been examined by combined gas chromatography-mass spectrometry. The structures of a number of previously unreported compounds have been confirmed by synthesis and Chromatographic comparisons. Compounds identified in these secretions include fatty acids, esters, amides, keto alcohols, diols and spiroacetals. These chemical findings are in agreement with taxonomic revisions based on other criteria.

    Effect of short-term energy intake level and exercise on oxygen consumption in men (1986)
    Springer
    European journal of applied physiology 55 (1986), S. 198-201

    Notizen: Summary The influence of short-term energy intake and cycle exercise on oxygen consumption in response to a 1.5 MJ test meal was investigated in ten young, adult men. On the morning after a previous day's “low-energy“ intake (LE regimen) of 4.5 MJ, the mean resting oxygen consumption increased by 0.7 ml · kg−1 · min−1 after the test meal (P〈0.025). After a “high-energy“ intake (HE regimen) of 18.1 MJ, the resting measurement was unchanged (+0.4 ml · kg−1 · min−1) after the meal (n.s.). These trends are the reverse of what would be expected if oxygen consumption in response to feeding is a factor in the acute control of body weight. The mean fasting oxygen consumption during cycle exercise at 56% of $$\dot V_{O_{2max} } $$ (constant work) for both LE and HE prior intakes was not different at 31.1 ml · kg−1 · min−1. Oxygen consumption during exercise increased after feeding by 0.5 ml · kg−1 · min−1 on the LE regimen (n.s.) and decreased by 1.2 ml · kg−1 · min−1 on the HE regimen (n.s.). These results are also the reverse of what would be expected if oxygen consumption in response to exercise is related to short-term energy intake.
