After 7 days, 35% of the flies exposed to 2,5-dimethylfuran were dead. However, exposure to this compound did not significantly degrade the flies' performance in the geotaxis assay. What explanation could be given to explain these results?
Homework Answers
Geotaxis assay is a traditional adult climbing assay used to check the mobility of flies (behavioral asay). In this assay, the flies are put in a vial and observed how it moves & also the time taken to cross certain distance in the vial. In other words, this assay can be used check the natural tendency of the fly to move against the gravity.
volatile oragnic compound 2,5-dimethylfuran ( 2,5 DMF) ia an ether. Exposure of 2,5-dimethylfuran in flies leads to induce reactive oxygen species. Reactive oxygen species inturn cuases lipid peroxidation and results in oxidative stress induced cell death (dopaminergic neurons).
The flies may be fed with antioxidant such as vitamin E by scavenging the free radicals and thereby will not affect the performance of fly.

Researchers have concluded that exposure to anesthesia at a young age (7 days old) in rats has led to degeneration in the brain and learning deficits. This led them to hypothesize that similar effects may also be seen in humans, especially in an age of neonatal care and infants undergoing surgery to correct defects. To test this hypothesis, another team of researchers recruited 105 pairs of siblings. One sibling was exposed to general anesthesia before they were 36 months old...

Several studies suggest that breast-fed babies become more intelligent children than formula-fed babies. One such study (Mortensen, Michaelsen, Sanders, & Reinisch, 2002*) involved a sample of over 3,000 women and men born in Copenhagen, Denmark, between October 1959 and December 1961. The samples were divided into five categories based on duration of...

They grouped subjects according to self-reported stress-induced eating habits: consistently eating more (hyperphagics) or less (hypophagics) when stressed. Each subject was then exposed to one of three social situations: (1) a social inclusion condition in which subjects were told that a confederate partner had approved...

Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
