    Tunable electron-hole gases in gated InAs/GaSb/AlSb systems (1997)

    Notes: Gated structures have been fabricated on the InAs/AlSb/GaSb system enabling the control of the relative electron and hole carrier densities in these type II crossed band gap structures. By using insulated gates, a wide gate voltage range, with very low leakage levels, is obtained, allowing the study of these systems from electron dominated transport through to hole dominated. Associated with this transition, a change from positive to negative transconductance is observed. Studies of the quantum Hall effect show features related to both electron and hole Landau level formation with the crossover from electron to hole dominated transport found to be a function of the perpendicular magnetic field. © 1997 American Institute of Physics.

    A NOTE ON THE EATING BEHAVIOUR OF CHILDREN VARYING IN WEIGHT (1976)

    Notes: Summary Eight pairs of six to fourteen year old children, one member obese and one nonobese (matched on age group, sex, and number of children eating together), were observed unobtrusively as they ate lunch in a school cafeteria. A pattern of eating found in obese adults (faster rate of biting, less chewing, and more extraneous responses during eating) was found in similar form in these mildly obese children. The results were discussed in terms of early onset of behaviour patterns relevant for the prevention and treatment of obesity.

    The Predictors of Unsuccessful Transition to Foster Care (2001)

    Notes: The placement movements of 235 children entering foster care over a 12-month period were followed up 4 months after referral into care. Baseline and follow-up measures of the 170 children who were still in care at follow-up were also compared. Results indicated that adolescents with mental health or behavioural problems were the least likely to achieve placement stability or to display improved psychological adjustment in care. In fact, unsatisfactory transition to foster care was found to be so prevalent among these children that conventional foster family care should be considered unsuitable for them. The paper concludes that there is an urgent need for a wider range of alternative care options for the adolescent population.

    Isozymic Characterization of Three Mating Groups of the Tetrahymena pyriformis complex (1980)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 27 (1980), S. 0

    Topics: Biology
    Notes: SYNOPSIS. Strains of 3 unnamed mating groups of the Tetrahymena pyriformis complex have been subjected to starch gel electrophoresis followed by staining the gels for the enzymes isocitrate dehydrogenase (NADP), tyrosine aminotransferase, and tetrazolium oxidase (superoxide dismutase). With respect to the electrophoretic mobilities of these enzyme systems, the mating groups referred to here as 5, 13 and 14 are very similar to Tetrahymena americanis (syngen 2), the most common North American species of the complex.Cultures in our collection labeled Tetrahymena cosmopolitans (formerly syngen 4) are either amicronucleate, with unique isozyme patterns, or micronucleate cells which mate with and have isozyme patterns similar to Tetrahymena canadensis (syngen 7). Immature progeny have been derived from crosses between the latter strains and T. canadensis recently collected in Colorado. The amicronucleate strains are now placed in the Tetrahymena sp. category, and we conclude that strains identifiable as T. cosmopolitanis are no longer available.The reliability of isozymes as characters in ciliate taxonomy was evaluated by comparing the present results for 3 enzymes in 15 groups of strains (syngens and phenosets) that had been compared in an earlier study. These enzyme systems gave correlation coefficients (r) of 0.75 or higher in the separate studies, and can be considered useful diagnostic traits. Other enzymes that were present at threshold levels of detectability or varied highly in concentration from species to species are too unreliable to be of diagnostic value. Some of the strains in the complex are so evolutionarily divergent at the molecular level that we have difficulty finding growth and electrophoretic conditions under which orthologous enzyme activities can be detected simultaneously for all the strains being compared.

    Amoeboid Locomotion of Naegleria gruberi: the Effects of Cytochalasin B on Cell-Substratum Interactions and Motile Behaviour (1990)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 37 (1990), S. 0

    Notes: The major manifestations of amoeboid locomotion in Naegleria—cytoplasmic streaming, pseudopod production, cell polarity and focal contact production—require that the actin-based cytoskeleton be extremely dynamic. Whether these features are causally linked is unclear. In an attempt to answer this question we have used the fungal product cytochalasin B (cyt B) to dissect the motility process. This drug can perturb the organisation of actin filaments both in vivo and in vitro. Essentially cyt B acts as a molecule which can cap the barbed ends of actin filaments. Not surprisingly therefore cyt B has an effect on rates of actin polymerization and the dynamic state of actin in the cytoplasm.We have found that cyt B has a profound effect on focal contact production and breakdown. Within minutes of addition of cyt B focal contact production ceases, existing focal contacts are stabilised but cytoplasmic streaming and pseudopod production are not blocked. In conclusion it is now clear that the state of actin required for focal contact production is different from that required for pseudopod extension and cytoplasmic streaming.
