Investigations on the Mitochondria of the Housefly, Musca Domestica L
1. The ATPase activity of insect mitochondria has been investigated. A comparison was made to determine the distribution and nature of such activity in other isolated fractions of the house fly, Musca domestica L. 2. The ATPase in insect mitochondria is specific in that orthophosphate can be cleaved only from ATP. The Michaelis-Menten constant K(8) = 2.78 x 10(-3)M and V(max.) = 76 micrograms P...
متن کاملAnaerobic metabolism in the housefly, Musca domestica L.
Adult and immature individuals of many insect species can survive anaerobic conditions for periods ranging from 4 hr. to 4 days, and even in a few cases for longer periods up to 56 days (see Brand, 1946, for numerous references). The present paper describes an investigation into some effects of anoxia on adult Musca domestica. A preliminary account of part of this work has been published (Heslo...
متن کاملSex- and age-related changes in the biophysical properties of cuticular lipids of the housefly, Musca domestica.
We examined the biophysical properties of cuticular lipids isolated from the housefly, Musca domestica. Melting temperatures (Tm) of surface lipids isolated from female houseflies decreased from 39.3 degrees C to 35.3 degrees C as the females attained sexual maturity and produced sex pheromone, whereas those prepared from males did not change with age. Lipids melted over a 10-25 degrees C tempe...
متن کاملRegulation of Ovarian Ecdysteroid Production in the Housefly, Musca domestica
Highly purified Musca ecdysteroidogenin (ESG) was obtained by extracting housefly heads with an acid-ethanol-urea procedure followed by desalting on a Sephadex G25F column and fractionation on a Sephadex G50F column. Further fractionation was done on a semi-preparative C18 reverse-phase HPLC column with an acetonitrile gradient in 0.1% trifluoroacetic acid in water. Ecdysteroidogenic activity e...
متن کاملIsolation of fungi from housefly (Musca domestica L.) at Slaughter House and Hospital in Sanandaj, Iran.
OBJECTIVE Houseflies have long been regarded as potential carriers of microorganisms especially fungi. Since pathogenic microorganisms are widespread in the hospital environment, there is abundant opportunity for flies to become contaminated and in turn to contaminate the patient environment and residential regions. The aim of this study was to isolate and identify fungi from the slaughter hous...
