Le 27 septembre 1792, un critique anonyme affimait qu'll fallait lire Sade "pour voir jusqu'ou peut aller le delire de l'imagination humaine." Pourtant, la lecture des trois versions de Justine nous laisse une impression sensiolment differente: la stylisation romanesque, en attenuant le spontaneite du desir confere a l'oeuvre une certaine austerite [...]  Lire la suite

Incubation of liver slices from vitamin K-deficient as well as from warfarin-pretreated rats, but not from normal rats, required the presence of vitamin KI to form and/or release factor VII into the medium. Vitamin K analogues having vitamin K-like or antagonist activity in intact animals, showed the same activity in vitro. In slices from vitamin K-deficient rats, low concentrations of warfarin (< 10^-4M) completely inhibited the response to low concentrations of vitamin K1 (< 10^-6M) without inhibiting total protein synthesis. Concentrations of warfarin which were found to inhibit total protein synthesis (>10^-4M), were required in order to inhibit the response …  Lire la suite

This thesis represents an attempt to use empirical methods to analyze the campaign period preceeding the general election of 1965 as a way of gaining some factual insights into the basic problems which beset the Canadian federation between 1960 and 1965. Data was collected from three basic sources: public opinion surveys, a sample of election candidates, and the editorial columns of twenty Canadian daily newspapers. It is the contention of the author that the 1965 campaign and certain related events constitute a microcosm of the period 1960-1965 and that this period represents a unique phase in the history of Canadian …  Lire la suite

The Deoxynucleoside triphosphate pools in bath asynchronous and synchronous cultures of mammalian cells were examined. The pools were examined in asynchronous cultures of HeLa, Chinese hamster and mouse L-cells, and it was found that the absolute amounts of the four triphosphates varied between the cell lines, and that the ratios of the amounts of the four triphosphates varied within each cell line. In a highly synchronous population of HeLa cells it was found that the pools of all four aeoxynucleoside triphosphates fluctuated in a similar, cyclic manner. The nature of these fluctuations was determined, and it was shown that in …  Lire la suite

Local anaesthetics with different combinations of CO2 and pH were applied to sheathed and desheathed frog nerves during conventional stimulation and recording of the compound action potential. While CO2 (1-50%) or local anaesthetic (1 mM) caused a small degree of block, together they had much greater effect, greater at a higher pH (7.3). The permeability of the nerve sheath to radioactive lidocaine and sucrose was measured by perfusing these solutions through a tube of isolated sheath. Samples were taken from a bath surrounding the sheath. The permeability to the anaesthetic was proportional to the fraction of non-ionized lidocaine. It was …  Lire la suite

A soluble factor, capable of inducing blastic transformation of leukocytes in culture has been described. This substance (BF) was obtained from culture medium derived from mixed leukocyte cultures: its activity was tested in cultures derived from one donor. Leukocytes subjected to 2,000 r x-irradiation were still capable of producing BF. In contrast, mixtures of purified lymphocytes, untreated or irradiated, did not release factor. The response of purified lymphocytes to BF was also much reduced compared to the reaction of non-fractionated leukocytes. Interaction between lymphocytes and BF was however demonstrated by culturing cells preincubated with phytohaemagglutinin and by the capacity of …  Lire la suite

The competitive binding of oleate and bilirubin to albumin was evaluated in vitro using three different methods: reserve albumin binding capacity by HBABA dye, Sephadex G-25 gel filtration, and bilirubin spectral curves in a bilirubin-albumin solution of molar ratio 1.6. Both the Sephadex G-25 and spectral curve techniques showed no bilirubin displacement until the concentration of oleate exceeded 1.5 mEq/L. At this concentration of oleate, there was already a 40 - 50% depression in HBABA dye binding, suggesting nonspecificity of the dye for bilirubin and its competitive and non-competitive anions for sites on albumin, a finding confirmed by drug-bilirubin binding …  Lire la suite

Studies with human subjects show that aluminum workers in refining and reduction plants have a significant increase in serum aluminum and in prothrombin time. Serum intestinal alkaline phosphatase, serum acid phosphatase, and blood ATP levels are significantly decreased.  Lire la suite
