HEBERLEIN, Ulrike; Univ. of California, San Francisco: Drosophila and molecular underpinnings to ethanol susceptibility Alcohol abuse and alcoholism are among the most devastating social and medical problems in our society, yet little is known about the mechanisms by which ethanol regulates behavior. Our laboratory uses the fruitfly Drosophila, with its accessibility to behavioral, genetic, and […]

Alcohol and Modern Human Health
KLATSKY, Arthur L.; Kaiser Permanente Medical Care Program, Oakland, CA: Alcohol and Modern Human Health Substantial medical risks of heavy drinking and existence of a safe limit have long been evident. Modern epidemiologic studies also indicate a lower morbidity and mortality risk among lighter drinkers. Defining “heavy” as 3+ drinks/day, the alcohol-mortality relationship is a […]
Adventures in Fly World, or, Building a Better Bottle
DICKINSON, M. H.; Caltech: Adventures in Fly World, or, Building a Better Bottle Drosophila melanogaster has long been an essential model system in the fields of Cell Biology and Development. Many of the presentations in this symposium testify to the increasing use of Drosophila to address organismal questions, such as the influence of alcohol on […]
Vitellin-like proteins in larval Crustacea potential biomarkers of xeno-oestrogen exposure
SANDERS, , M.B.*; BILLINGHURST, , Z.; DEPLEDGE, , M.H.; CLARE, , A.S; University of Plymouth, U.K.; Plymouth Environmental Research Centre, U.K.; Plymouth Environmental Research Centre, U.K; University of Newcastle, Newcastle-upon-Tyne, U.K.: Vitellin-like proteins in larval Crustacea: potential biomarkers of xeno-oestrogen exposure While the ability of xeno-oestrogens, like 4-n-nonylphenol (4-NP), to disrupt the natural hormonal systems […]
The occurrence of intersex in Japanese freshwater crab
ARIZONO, Koji; TAKAHASHI, Tohru; AYAKI, Toshikazu; Prefectural University of Kumamoto; Kumamoto Health Science University ; Nagasaki Prefectural University: The occurrence of intersex in Japanese freshwater crab Tributylin (TBT)-induced imposex phenomena have been reported only in mollusks. Our findings reveal that imposex is not a phenomenon exclusive to mollusks. The imposex phenomenon has been found to […]
The influence of insect juvenile hormone agonists on metamorphosis and reproduction in estuarine crustaceans
MCKENNEY, JR., C.L.; USEPA, NHEERL, Gulf Ecology Division: The influence of insect juvenile hormone agonists on metamorphosis and reproduction in estuarine crustaceans Comparative developmental and reproductive studies were performed on several species of estuarine crustaceans in response to three juvenile hormone agonists (JHAs). Larval development of the grass shrimp, Palaemonetes pugio, was greater than two […]
The Hormones Regulating Crustacean Growth, Metabolism, and Reproduction Multiple Targets for Endocrine Disruption
CHANG, E.S.; Univ. of Caliifornia, Bodega Marine Lab., Bodega Bay: The Hormones Regulating Crustacean Growth, Metabolism, and Reproduction: Multiple Targets for Endocrine Disruption Crustaceans are ideal model organisms for the study of endocrine disruption and stress physiology in aquatic invertebrates. This is due to their ecological and economic importance and to the relatively extensive amount […]
Testosterone-Fatty Acid Esterification A Unique Target for the Endocrine Toxicity of Tributyltin to Gastropods
LEBLANC, G.A.; STERNBERG, R.; GOODING, M.P.; GUAL, G.J.; North Carolina State Univ.: Testosterone-Fatty Acid Esterification: A Unique Target for the Endocrine Toxicity of Tributyltin to Gastropods Contamination of the marine environment with tributyltin (TBT) has caused a global occurrence of endocrine toxicity – imposex – whereby female gastropods express male sex traits. Imposex has been […]
Response of Drosophila melanogaster to insect growth regulator insecticides
WILSON, T.G.; ASHOK, M.; PURSLEY, S.; Ohio State University, Columbus OH; Colorado State University, Fort Collins: Response of Drosophila melanogaster to insect growth regulator insecticides Although Drosophila melanogaster is not a pest insect, studies of field populations demonstrate that this insect responds to insecticide usage by evolving resistance. We have studied resistance to the insect […]
Population-level response of the mysid, Americamysis bahia, to varying thiobencarb concentrations based on age-structured population models
RAIMONDO, Sandy; MCKENNEY, JR., Charles L.; US Environmental Protection Agency; US Environmental Protection Agency: Population-level response of the mysid, Americamysis bahia, to varying thiobencarb concentrations based on age-structured population models To fully understand the potential long-term ecological impacts a pollutant has on a species, population-level effects must be estimated. Since long-term field experiments are typically […]
