The strong inwardly rectifying potassium channels Kir2.x are involved in maintenance and control of cell excitability. Recent studies reveal that the function and localization of ion channels are regulated by interactions with members of the membrane-associated guanylate kinase (MAGUK) protein family. To identify novel interacting MAGUK family members, we(More)
Developmental stages of mammary glands influence their susceptibility to initiating events related to carcinogenesis. The "window of susceptibility" to mammary carcinogenesis is classically defined as the time in early puberty when the mammary gland morphology is most sensitive to initiation events. Administration of the polyaromatic hydrocarbon,(More)
A liquid chromatographic method has been developed for the determination of free fatty acids in butter. The fatty acids are converted to the p-bromophenacyl esters, via a crown ether-catalyzed reaction, without separation from the other butter components. The esters are separated on a C18-bonded silica column by using an acetonitrile-water solvent gradient(More)
A method is described for the gas-liquid chromatographic determination of traces of selenium in marine biological materials. The method is based on the reaction of Se(IV) with bromo- and chloro-substituted 1,2-diaminobenzenes. The benzoselenadiazoles so formed are sensitive to electron capture detection. The sample is digested in a nitric-perchloric acid(More)
Lead levels in the deciduous teeth of 292 Queensland children aged between 4 and 9 years are reported. Samples were obtained through the cooperation of parents of children attending kindergartens throughout the State in 1981. Information relating to the child's place of residence, home environment and parents' occupation was also gathered with the aid of a(More)
