Published: 21 February 2024
...Morag F. Dick; Keith A. Hobson; Christopher G. Guglielmo ABSTRACT Dietary n-3 long chain polyunsaturated fatty acids (LCPUFAs) are hypothesized to be natural doping agents in migratory shorebirds, enabling prolonged flight by increasing membrane fluidity and oxidative capacity of the flight muscles...

... muscle, heart and liver of ruby-throated hummingbirds ( Archilochus colubris ). The GLUTs examined were detected in nearly all tissues tested. Hepatic GLUT1 was minimally present in whole-tissue homogenates and absent win PM fractions. GLUT5 was expressed in flight muscles at levels comparable to those...

...James F. Staples; Erin L. Koen; Terence M. Laverty SUMMARY In the flight muscles of European bumblebees, high activities of fructose-1,6-bisphosphatase (FbPase) relative to phosphofructokinase (PFK)have suggested a thermogenic `futile cycle' important for regional endothermy. We find generally low...

...David T. Sullivan; R. MacIntyre; N. Fuda; J. Fiori; J. Barrilla; L. Ramizel SUMMARY In Drosophila flight muscles, glycolytic enzymes are co-localized along sarcomeres at M-lines and Z-discs and co-localization is required for normal flight. We have extended our analysis of this phenomenon...

...Gerhard Wegener; Volker Tschiedel; Paul Schlöder; Osamu Ando SUMMARY The main blood sugar of locusts is trehalose, which is hydrolysed to two glucose units by trehalase. Homogenates of locust flight muscles are rich in trehalase activity, which is bound to membranes. A minor fraction of trehalase...

.... However, the strength and duration of the contralateral response is always diminished compared with those of the injection side, which would be expected for effects mediated by diffusion across the ganglion. An exception is the short-term activation of adjacent flight muscles by octopamine. In this case...

...HARALD ESCH; FRANZ GOLLER The big indirect flight muscles in the thorax of honeybees and bumblebees show two modes of action: they contract with ‘conventional’ twitches in response to slowly repeated muscle potentials and go into tetanus at higher muscle potential frequencies. They can also...

.... A very thin filament was seen connecting the A-filament to the Z-line in insect fibrillar flight muscle (Auber & Couteaux, 1963, cited by White, 1983 ) and was thought to be the basis for the high resting tension of that muscle ( White, 1983 ). Connecting filaments have now also been seen...
