Characterization And Structure-Function Studies Of Human Liver Flavin Monooxygenase Isozyme 3 (Fmo3), Orhan Adali, Richard M. Philpot

Turkish Journal of Zoology

The activity of the flaving-containing monooxygenase (FMO EC 1.14.13.8) can be modulated by a number of nitrogen-containing compounds in a manner that is both isoform and effector-dependent. We showed that the direction (activation or inbihiton) and extent of modulation can also be dependent on substrate concentration. The native human liver FMO3 and arg 433 mutant FMO3 catalyze the methimazole reaction with similar Km values. However, the mutant FMO3-catalyzed reaction was affected differently by high concentration of imipramine, imipramine causing inhibition of activity. Our results suggest that the response of FMO3 to imipramine involves a distribution of compounds between two sites …

The effects of eyestalk ablation on maturation, moulting and spawning in Penaeus semisulcatus were investigated in this study. Twelve males and 12 eyestalk-ablated and 12 non-ablated, all individually marked females were stocked into a 12-ton maturation tank. All the ablated females moulted in 9.08±1.68 days and first spawning occurred 16.75±3.41 days following eyestalk ablation. While all the ablated females spawned, producing an average of 177.000 ±133.340 eggs, only three non-ablated females spawned, producing average of 23.216±16.957 eggs during a period of 45 days (P0.05). Average nauplii production per female was 81.574±55.126 for ablated and 13.397±11.535 for non-ablated ones (P

Two New Sex Determining Factors ( M V , F D ) In Housefly, (Musca Domestica) Populations In Turkey, Şükran Çakir

Turkish Journal of Zoology

In most strains of the common housefly, Musca domestica, sex is genetically determined by the presence or absence of a Y chromosome with a dominant male determining factor, M. Standard trains have an XX-XY mechanism. In certain laboratory and natural populations, however, neither females nor males have the Y chromosome. These non-standard populations have autosomal mechanisms for sex determination. In the present study, the existence of two new autosomal sex determining factors, M V and F D , in housefly populations in Turkey was determined.

Alarm Calls Affect Foraging Behavior In Eastern Chipmunks (Tamias Striatus), Jessica K. Baack

Masters Theses

I used playback experiments to test whether alarm calls affected the foraging behavior of Eastern chipmunks (Tamias striatus). I subjected chipmunks, foraging at artificial feeding stations, to three playback treatments (silent, control noise, and alarm call) and examined changes in vigilant and foraging behavior. Chipmunks responded to alarm calls with a greater degree and duration of vigilant behavior, such as look-ups and alert postures. Chipmunks also ran a shorter distance to cover, ran more directly to cover, and took longer to re-emerge from the burrow after hearing an alarm call. Alarm calls caused individuals to spend more time …

Recent Trends In Water Clarity Of Lake Pontchartrain, J.C. Francis, M.A. Poirrier

Gulf and Caribbean Research

An analysis of Secchi disk transparency observations from 3 sites on the Lake Pontchartrain Causeway indicates that water clarity has increased at the north shore and mid-lake sites, but has not changed at the south shore site. Louisiana Department of Environmental Quality data from 1986 through 1995 were used in the analysis. Further analysis indicates that the increased transparency was not caused by changes in salinity or wind speed. The best explanation for the observed increase is the cessation of shell dredging in 1990.
