Trophectoderm Differentiation In The Bovine Embryo: Characterization Of A Polarized Epithelium., L C Barcroft, A Hay-Schmidt, A Caveney, E Gilfoyle, E W Overstrom, P Hyttel, A J Watson Nov 1998

Trophectoderm Differentiation In The Bovine Embryo: Characterization Of A Polarized Epithelium., L C Barcroft, A Hay-Schmidt, A Caveney, E Gilfoyle, E W Overstrom, P Hyttel, A J Watson

Obstetrics & Gynaecology Publications

Blastocytst formation is dependent on the differentiation of a transporting epithelium, the trophectoderm, which is coordinated by the embryonic expression and cell adhesive properties of E-cadherin. The trophectoderm shares differentiative characteristics with all epithelial tissues, including E-cadherin-mediated cell adhesion, tight junction formation, and polarized distribution of intramembrane proteins, including the Na-K ATPase. The present study was conducted to characterize the mRNA expression and distribution of polypeptides encoding E-cadherin, beta-catenin, and the tight junction associated protein, zonula occludens protein 1, in pre-attachment bovine embryos, in vitro. Immunocytochemistry and gene specific reverse transcription--polymerase chain reaction methods were used. Transcripts for E-cadherin and …


"...To Produce The Highest Type Of Manhood And Womanhood": The Ontario Housing Act, 1919, And A New Suburban Ideal, Jason Gilliland, Matt Sendbuehler Mar 1998

"...To Produce The Highest Type Of Manhood And Womanhood": The Ontario Housing Act, 1919, And A New Suburban Ideal, Jason Gilliland, Matt Sendbuehler

Geography & Environment Publications

While most scholars generally focus on the failings of the post-WWI Federal-Provincial housing scheme in Canada, we contend that it had far-reaching implications for three major facets of urbanism: housing policy, town planning, and residential architecture. We do so primarily through an examination of the impacts of the Ontario Housing Act, 1919, in the context of contemporary visions of ideal residential environments.

In the 1920s, a major reconceptualization of planning and architecture generated a new ideology of house, home and city which intended to remake existing cities and to create new, efficient and healthy settlements. The ideal city featured increasingly …


Claims On Housing Space In Nineteenth-Century Montreal, Jason Gilliland, Sherry H. Olsen Mar 1998

Claims On Housing Space In Nineteenth-Century Montreal, Jason Gilliland, Sherry H. Olsen

Geography & Environment Publications

Space per person is a fundamental measure of equity in an urban society. From small samples of the Montreal population over the years 1861-1901, we infer substantial improvement in the average dwelling space available per person, but an extreme and persistent inequity in the distribution among households. The housing market remained polarised in terms of class and cultural identity. As crowding diminished, urban density increased, and the problem of working-class housing became, increasingly, one of collective rather than individual space. Families, through networks of kinship and neighbouring, found new ways to exert some control over vital urban micro-spaces. In a …


Fornix Lesions Can Facilitate Acquisition Of The Transverse Patterning Task: A Challenge For "Configural" Theories Of Hippocampal Function., T J Bussey, E Clea Warburton, J P Aggleton, J L Muir Feb 1998

Fornix Lesions Can Facilitate Acquisition Of The Transverse Patterning Task: A Challenge For "Configural" Theories Of Hippocampal Function., T J Bussey, E Clea Warburton, J P Aggleton, J L Muir

Brain and Mind Institute Researchers' Publications

Configural theories of hippocampal function predict that hippocampal dysfunction should impair acquisition of the transverse patterning task, which involves the concurrent solution of three discrimination problems: A+ versus B-; B+ versus C-; and C+ versus A-. The present study tested this prediction in rats using computer-graphic stimuli presented on a touchscreen. Experiment 1 assessed the effects of fornix lesions when the three problems were introduced sequentially (phase 1: A+ vs B-; phase 2: A+ vs B-, B+ vs C-; phase 3: A+ vs B-, B+ vs C-, C+ vs A-). Fornix lesions significantly facilitated acquisition of the complete transverse patterning …


Acts Of Parliament: Privatisation, Promulgation And Crown Copyright – Is There A Need For A Royal Royalty?, Mark Perry Jan 1998

Acts Of Parliament: Privatisation, Promulgation And Crown Copyright – Is There A Need For A Royal Royalty?, Mark Perry

Law Publications

The road of privatisation of government assets is littered with the debris of mishaps and oversights. One clear illustration is the history and effect of the sale of the Government Printing Office (GPO) in 1990. Within the sale process there was a failure to ensure adequate consideration of the policy implications from an important perspective, namely the effect of privatising the means of promulgation of the normative materials of the State. Furthermore, there was no enquiry into the dubious assumptions made as to Crown Copyright in legislation.

Intellectual property rights in primary legal materials create a dilemma for policy makers. …


Federalising The Aborigines? Constitutional Reform In The Late 1920s, Fiona Paisley Jan 1998

Federalising The Aborigines? Constitutional Reform In The Late 1920s, Fiona Paisley

Aboriginal Policy Research Consortium International (APRCi)

This paper considers arguments in favour of federal responsibility for indigenous affairs provided to the 1927-29 Royal Commission on the Constitution. Various humanitarian organisations, including women's groups, argued that the future of the Aborigines in Australia was a matter of national importance and was above state and federal politics. Constitutional acknowledgement of Aboriginal Australians as the original owners of the land would mark Australia's progress as a modern nation


Beliefs About Consciousness And Reality Of Participants At ‘Tucson Ii’, Imants Barušs, Robert J. Moore Jan 1998

Beliefs About Consciousness And Reality Of Participants At ‘Tucson Ii’, Imants Barušs, Robert J. Moore

Psychology

In previous studies we had found correlations between the material-transcendent dimension underlying the Western intellectual tradition and the diversity of ideas concerning consciousness. In the course of our work we developed the Beliefs About Consciousness and Reality Questionnaire that could be used for measuring fundamental beliefs about consciousness and reality. A survey of participants at the scientific meeting Toward a Science of Consciousness 1996 “Tucson II” was conducted using this questionnaire. Results from 212 respondents indicated scores substantially in the transcendent direction, both for scales underlying the questionnaire as well as for some of its individual items, relative to a …


Grapefruit Juice-Drug Interactions, David G. Bailey, J. Malcolm, O. Arnold, J. David Spence Jan 1998

Grapefruit Juice-Drug Interactions, David G. Bailey, J. Malcolm, O. Arnold, J. David Spence

Department of Medicine Publications

The novel finding that grapefruit juice can markedly augment oral drug bioavailability was based on an unexpected observation from an interaction study between the dihydropyridine calcium channel antagonist, felodipine, and ethanol in which grapefruit juice was used to mask the taste of the ethanol. Subsequent investigations showed that grapefruit juice acted by reducing presystemic felodipine metabolism through selective post-translational down regulation of cytochrome P450 3A4 (CYP3A4) expression in the intestinal wall. Since the duration of effect of grapefruit juice can last 24 h, repeated juice consumption can result in a cumulative increase in felodipine AUC and C(max). The high variability …
