In this study we report on the adsorption behavior of end-attaching triblock and diblock copolymers. The triblock copolymers consist of relatively short PEO end blocks and a much longer PS middle block or, in one case, of zwitterionic end groups with a PS middle block. The diblock materials consist of a PEO block of fixed length and varying polystyrene lengths. A silicon wafer with an oxide layer is used as the surface, and adsorption takes place from toluene; only the end groups adsorb, leaving the polystyrene block dangling in solution. We find that diblock copolymers which range from symmetric to moderately symmetric obey the scaling law for the surface coverage which was proposed in the theory of Marques and Joanny (i.e., sigma is-proportional-to 1/N(A), where N(A) is the number of segments in the adsorbing block). However, we find that for triblock copolymers of comparable asymmetry the surface coverage scales according to the relationship sigma is-proportional-to 1/beta2, where beta is the ratio of the size of the nonadsorbing block to that of the adsorbing block. This implies that moderately symmetric triblock copolymers behave like highly asymmetric diblock copolymers; the adsorption behavior is dominated by the nonadsorbing block size. Our experiments demonstrate the observation of extremely long-lived nonequilibrium states. On the basis of these observations we propose a simplified version of a recent theory of adsorption which is capable of qualitatively describing much of the experimentally observed phenomena.

The surface compositions of a series of random copolymers of styrene and deuteriostyrene have been determined by SIMS. The mechanism of fragmentation during the SIMS process is examined, and the contribution from naturally occurring isotopes is evaluated. The data are shown to fit a model of a completely random copolymer system if they are corrected for the effects of impurities introduced in the syntheses and for the contribution from C-13. [less ▲]

Pour comprendre autrui, il faut y mettre du sien. S'il est une affirmation commune aux auteurs qui s'inscrivent dans la conception inférentielle de la communication, c'est bien celle-là. Non seulement les communicateurs doivent se montrer de bonne volonté et manifester leur préférence pour la coopération mais encore ils doivent réquisitionner leur système cognitif au service de l'énonciation d'autrui. Le modèle du code avait oblitéré ce rôle actif des partenaires de l'échange, au profit d'un codage automatique qui ne paraissait requérir aucun effort, aucun appel à l'interprétation, l'énonciation véhiculant non seulement le mot mais sa pleine compréhension. Ce mémoire étudie les principes qui sous-tendent le modèle inférentiel chez 5 auteurs : Grice, Lewis, Searle, Sperber & Wilson et Livet. [less ▲]

We present four children from two families with the typical 11q- phenotype resulting from an unbalanced segregation of a parental translocation. In the first family, the father had a 46,XY,t(5;11)(q24;q23.3) constitution. The father of the three other children had a 46,XY,t(11;17)(q23;p13) translocation. Despite associated partial deletion, three of the children had a typical 11q- phenotype. The fourth one, whose pregnancy was terminated in the second trimester, had a hypoplastic left heart but no other considered gross anomalies. A review of 36 previous cases, including 5 due to translocations (4 familial rearrangements, and 1 of unknown origin) is given with emphasis on the relationships between break-points and phenotype. Undescribed manifestations in our patients include agenesis of corpus callosum adactyly and malrotation of the gut. [less ▲]

To clarify the controversy about the management and prognosis of human chorionic gonadotropin-producing seminoma, the records of 132 patients with abnormal human chorionic gonadotropin values treated with radiotherapy were analyzed. METHODS AND MATERIALS: The records of 1169 patients with pure seminoma treated in 10 institutions were screened for serum or urinary human chorionic gonadotropin. One hundred and thirty two patients with elevated human chorionic gonadotropin were found: 96 Stage I, 20 IIA, 7 IIB, 8 III and 1 IV. Median age was 34 y., mean follow-up was 5.0 years [range 1-12 y]. All received infradiaphragmatic radiotherapy (median dose 30 Gy), 25 (2 Stage I, 11 IIA, 5 IIB and 7 III) supradiaphragmatic radiotherapy (median dose: 28.5 Gy) and 10 had also initial chemotherapy (3 Stage IIB 6 III and 1 IV). Patients were allocated to three groups according to human chorionic gonadotropin values: (a) moderate elevation: up to 10 times (104 pts), (b) high elevation: 10 to 100 times (20 pts), (c) very high elevation: over 100 times the upper limit of normal value (8 pts). RESULTS: The proportion of Stage I, II and III was 76%, 19%, 5% in the ME group versus 50%, 35%, 15% in the high elevation group (p < 0.05). In the very high elevation group there were 7 Stage I and 1 Stage IV. Of 132 patients, six died (three dead of disease, two suicides, one acquired immunodeficiency syndrome). The 5 years overall survival probability was 94%. There were seven recurrences (initial stage: 1 Stage I, 2 IIB, 3 III and 1 IV). Of these, there were one in-field recurrence, 3 out of field and 3 in both sites. In 5 of 7, the human chorionic gonadotrophin level was again elevated at recurrence. The 5 years recurrence-free-survival probability was 94% (98% for Stage I, 100% for Stage IIA and 65% for Stage IIB and III [p < 0.001 between I and IIB + III, p < 0.05 between IIA and IIB + III]). Four of the 7 recurrences were salvaged by chimiotherapy +/- radiotherapy. In the high elevation and very high elevation groups, the 5 years recurrence-free-survival was 88%, vs. 96% for the moderate elevation group (p = 0.10). CONCLUSION: Based on this series of patients, human chorionic gonadotropin production is not an unfavorable prognostic factor in pure seminoma. Even in the subgroups with high or very high human chorionic gonadotropin levels (who had a higher proportion of advanced stages), the prognosis remained excellent. In Stage I and IIA seminoma with abnormal human chorionic gonadotropin levels, recurrence rate after post-operative radiotherapy alone is extremely low. [less ▲]

Fourteen patients undergoing kidney transplantation were studied for evidence of the production of free radicals as assessed by the measurement of vitamin E (an index of lipid peroxidation) and of myeloperoxidase (a marker of neutrophil activation) in the systemic blood. Early (2 min) and late revascularization (30 min) of the kidney were respectively associated with a significant decrease of 35.5 and 40% of the initial level of plasma vitamin E. This consumption paralleled to the decrease of the vitamin E/total lipids ratio, a better indicator of vitamin E status. Heparin administration preceding renal artery clamping resulted in a twofold significant increase of baseline plasma myeloperoxidase (MPO) level (523 +/- 214 ng/ml). At kidney reperfusion, MPO concentration rose again and reached a maximum value of 1,653 +/- 882 ng/ml, indicating the presence of considerable neutrophil activation. A return to the baseline value was observed after 30 min of reperfusion. A short discussion about the possible origin of this MPO increase is given. Taken together, these data strongly suggest that free radical production, leading to lipid peroxidation phenomena, can occur within the early phase of kidney revascularization. Preliminary data using electron spin resonance with the spin-trapping technique strengthen this hypothesis. [less ▲]
