Posterior Gastro-Enterostomy in the Treatment of Peptic Ulceration

1. The broad trend of Surgical treatment in peptic ulceration is traced. Though the trend has been towards the more radical procedure of extensive gastrectomy several authorities maintain, with variable emphasis, that gastro-enterostomy is still a valuable procedure. 2. Attention has been drawn to the danger in comparing mortality rates where the age distribution of patients is not known. 3. Methods of reporting follow-up results is briefly discussed and the caution required in comparing results is stressed. A method of reporting results which allows of comparison with similarly reported results is used in the present investigation. 4. The material in this review consists of 330 posterior gastro-enterostomies performed for peptic ulceration between the years 1924 and 1937. Of these 270 were traced. 5. The results are given on a cumulative basis over a period of 20 years. The impact of site of ulceration, presence or absence of obstruction, age, sex and chronicity of ulcer on the results is analysed. 6. The curative effect of gastro-enterostomy per se as a treatment/ treatment of peptic ulceration has been estimated and found to he considerable, 7. The general results show that in round figures after a period of between 15 and 20 years, 50% are found to have recurrence of symptoms; 25% being no better or worse, 12.5% slightly improved and 12.5% markedly improved. 50% are symptom free. 8. The pathology of recurrence is discussed and the author is of the opinion that this is largely due to secondary ulceration at the stoma. 9. The danger of perfoiming gastro-enterostomy for gastric ulcer is stressed. 10. The place of gastro-enterostomy in the treatment of peptic ulcer is discussed and the only factors discerned which improve the results have been the presence of organic pyloric stenosis, old age and female sex. The tentative suggestion is made that when the mortality and morbidity rates for gastrectomy in the older age groups is better known, there may be a place for gastro-enterostomy in those age groups. 11. The mechanism by which the operation produces a favourable result is not obvious. Gastric acidity is, on the average, unchanged, high post-operative levels being consistent with good results. The gastric motility is also unchanged

Inuit Attitudes towards Co-Managing Wildlife in Three Communities in the Kivalliq Region of Nunavut, Canada

We explored Inuit attitudes towards co-managing wildlife in the Kivalliq Region of Nunavut, Canada, working in partnership with the hunters and trappers’ organizations of Igluligaarjuk (Chesterfield Inlet), Tikirarjuaq (Whale Cove), and Qamani’tuaq (Baker Lake). In mixed-methods interviews, study participants in the two coastal communities described dissatisfaction with polar bear (Ursus maritimus) management outcomes, in contrast to a general satisfaction with (or indifference to) the management of other species. Interviewees expressed concern about grizzly bear (Ursus arctos) and, more prominently, caribou (Rangifer tarandus groenlandicus) populations in Qamani’tuaq, the inland community. Researchers have predicted that conflicts specific to polar bear management could lead to regulations being ignored or even defied and endanger the entire system of wildlife co-management. Our results indicate that dissatisfaction over decisions is specific to polar bear management outcomes and does not necessarily apply to the broader system of wildlife co-management. The results suggest that the Nunavut wildlife co-management system is quite functional: polar bear issues aside, Inuit in Qamani’tuaq, Tikirarjuaq, and Igluligaarjuk are largely content with the current functioning of the wildlife co-management regime.Nous avons étudié les attitudes des Inuits à l’égard de la cogestion de la faune dans la région de Kivalliq, au Nunavut, Canada, en collaboration avec les organisations de chasseurs et de trappeurs d’Igluligaarjuk (inlet Chesterfield), de Tikirarjuaq (Whale Cove) et de Qamani’tuaq (Baker Lake). Dans le cadre d’entretiens effectués au moyen de diverses méthodes, les participants à l’étude des deux collectivités côtières ont exprimé leur mécontentement à l’égard des résultats de la gestion de l’ours polaire (Ursus maritimus), comparativement à leur satisfaction générale (ou à leur indifférence) quant à la gestion des autres espèces. Par ailleurs, les personnes interrogées ont exprimé des inquiétudes par rapport aux populations de grizzli (Ursus arctos) et des inquiétudes encore plus grandes par rapport aux populations de caribou (Rangifer tarandus groenlandicus) à Qamani’tuaq, la collectivité intérieure. Selon les chercheurs, les conflits en matière de gestion de l’ours polaire pourraient se traduire par le non-respect ou la non-considération des règlements, et mettre en danger le système de cogestion de la faune dans son ensemble. D’après nos résultats, le mécontentement à l’égard des décisions a précisément trait aux résultats de la gestion des ours polaires et ne concerne pas nécessairement le système général de cogestion de la faune. Selon les résultats, le système de cogestion de la faune du Nunavut est bien fonctionnel : mis à part la question des ours polaires, les Inuits de Qamani’tuaq, de Tikirarjuaq et d’Igluligaarjuk sont en grande partie satisfaits du fonctionnement actuel du régime de cogestion de la faune

Summer Movements of Radio-tagged Arctic Charr (Salvelinus alpinus) in Lake Hazen, Nunavut, Canada

Radiotelemetry was used to determine whether Lake Hazen arctic charr (Salvelinus alpinus) were anadromous and to determine movements of the charr within the lake. In 1995 and 1996, 62 and 55 charr, respectively, were captured, radio-tagged, and released back into the lake. A fixed data acquisition system recorded limited movements of radio-tagged charr in the upper reaches of the Ruggles River, the only outlet from the lake to the sea, in 1995. When movements of radio-tagged charr within Lake Hazen were monitored opportunistically in 1995, most of the relocated charr were found in warmer, more productive waters associated with inflowing streams. No movements of radio-tagged charr in the Ruggles River were recorded in 1996 when the data acquisition system was operated in the lower reaches of the river. These observations supported the conclusions of a study of Lake Hazen charr otolith strontium distribution that Lake Hazen charr were non-anadromous. The Ruggles River may be a detriment to anadromous behaviour because of its length (ca. 29 km), velocity (up to 2.25 m/s), and the year-round presence of aufeis (layered ice buildup). In summer, instead of migrating to the sea to feed, Lake Hazen charr appear to move to feed on abundant prey found in areas where inlet streams enter the lake.On a fait appel à la télémesure pour savoir si l'omble chevalier (Salvelinus alpinus) du lac de Hazen est anadrome et pour connaître ses déplacements dans le lac. On a capturé 62 ombles en 1995 et 55 en 1996 qu'on a munis de radio-émetteurs avant de les relâcher dans le lac. En 1995, un système fixe de collecte de données a enregistré les déplacements restreints des ombles munis de radio-émetteurs dans le cours supérieur de la rivière Ruggles, la seule décharge du lac dans la mer. Quand on a pu vérifier les déplacements de ces ombles dans le lac de Hazen en 1995, la plupart des poissons se trouvaient dans les eaux plus chaudes et plus productives associées à des ruisseaux d'arrivée. En 1996, après qu'un système de collecte de données a été installé dans le cours inférieur de la rivière Ruggles, on n'y a enregistré aucun déplacement des ombles munis de radio-émetteurs. Ces observations viennent étayer une étude sur la distribution du strontium otolithique chez l'omble du lac de Hazen, qui concluait que ce poisson n'était pas anadrome. Il se peut que la rivière Ruggles soit peu propice à un comportement anadrome en raison de sa longueur (env. 29 km), de sa vitesse (jusqu'à 2,25 m/s) et de la présence toute l'année d'un dôme de glace (Aufeishugel). En été, au lieu de migrer vers la mer pour se nourrir, l'omble du lac de Hazen semble se déplacer vers les zones où les ruisseaux se déversent dans le lac et qui contiennent des proies en abondance

Phylogeny of the Grasses (Poaceae) Revisited

The most robust previously published phylogeny for the overall structure of the grass family (Poaceae) shows three early diverging lineages and two major derived clades, the BEP clade and the PACCAD clade (Grass Phylogeny Working Group 2001). A few key taxa were incompletely sampled, however, and support for the BEP clade was moderate at best and relationships among the major lineages within the PACCAD clade remained unresolved. In addition, recent studies indicated that the sister group to Poaceae may be Joinvilleaceae and/or Ecdeiocoleaceae, the latter of which were not previously sampled. In this study, missing structural data were determined and analyzed as well as sequence data for ndhF and rbcL, the two most complete plastid sequence data sets. Sampling was increased with a particular focus on key taxa such as Danthoniopsis, Eriachne, Micraira, and Streptogyna and a representative of the outgroup, Ecdeiocoleaceae. A total of 61 ingroup and two outgroup taxa were analyzed using maximum parsimony for total data, and maximum parsimony, Bayesian inference, and neighbor joining for the molecular data. A strongly supported clade of ((Eriachneae, Isachne) Micraira) was recovered as a sister subfamily to Arundinoideae and excluded from Panicoideae. Arundinaria was strongly united with Bambusoideae. The position of Streptogyna was weakly supported among Ehrhartoideae, and is still unresolved. An outgroup effect on ingroup topology was observed, demonstrating that highly divergent outgroups may unpredictably alter ingroup relationships

Thermodynamics and Fractional Fokker-Planck Equations

The relaxation to equilibrium in many systems which show strange kinetics is described by fractional Fokker-Planck equations (FFPEs). These can be considered as phenomenological equations of linear nonequilibrium theory. We show that the FFPEs describe the system whose noise in equilibrium funfills the Nyquist theorem. Moreover, we show that for subdiffusive dynamics the solutions of the corresponding FFPEs are probability densities for all cases where the solutions of normal Fokker-Planck equation (with the same Fokker-Planck operator and with the same initial and boundary conditions) exist. The solutions of the FFPEs for superdiffusive dynamics are not always probability densities. This fact means only that the corresponding kinetic coefficients are incompatible with each other and with the initial conditions
