Abstract:
Ittoqqortoormiit est une petite ville située sur la côte nord-est du Groenland, à l’entrée du fjord de Scoresby Sund. Basée sur une économie cynégétique, la communauté était prospère jusqu’à la chute du marché des peaux mais, aujourd’hui, les possibilités d’embauche sont faibles et les habitants partent à la recherche d’un emploi dans le sud. Face à ces difficultés, la municipalité tente de redynamiser son économie et le tourisme paraît être une alternative intéressante. En effet, le tourisme polaire prend de l’ampleur dans l’ensemble de l’Arctique et le Scoresby Sund correspond, en termes de faune et de paysages, à la demande touristique. La région symbolise à elle seule le «véritable Arctique» que les visiteurs souhaitent vivre mais deux problèmes majeurs freinent le développement touristique à Ittoqqortoormiit. Le premier est le revers de la médaille de ce «véritable Arctique», sa difficulté d’accès. Les infrastructures manquent pour accueillir, en tout temps, le visiteur. Le deuxième problème empêchant Ittoqqortoormiit de bénéficier des revenus générés se trouve dans la forme même du tourisme d’aujourd’hui. Que ce soit le tourisme de croisière ou celui d’aventure, l’argent circule de mains occidentales en mains occidentales. Très peu d’argent est dépensé sur le territoire d’accueil et il ne bénéficie pas aux populations locales. Consciente de ces difficultés, l’agence de tourisme locale, Nanu Travel, s’emploie à rendre visible Ittoqqortoormiit au niveau international en offrant de nouvelles perspectives touristiques impliquant les Inuit.

Abstract:
Purpose. Arctigenin (ARG) is a natural lignan compound extracted from Arctium lappa and has displayed anticancer function and therapeutic effect in a variety of cancers. Arctigenin is mainly from Arctium lappa extract. It has been shown to induce autophagy in various cancers. However, as for whether arctigenin induces autophagy in gliomas or not, the specific mechanism is still worth exploring. Methods. Using CCK8, the monoclonal experiment was made to detect the proliferation ability. The scratch experiment and the transwell experiment were applied to the migration and invasion ability. PI/RNase and FITC-conjugated anti-annexin V were used to detect the cell cycle and apoptosis. Western blotting was used to determine the specified protein level, and constructed LC3B-GFP plasmid was used for analysis of autophagy.Results. Our research showed that ARG inhibited the growth and proliferation and invasion and migration of glioma cells in a dose-dependent manner (U87MG and T98G) and arrested the cell cycle and induced apoptosis. Interestingly, ARG induced autophagy in a dose-dependent manner. We applied Western blotting to measure the increase in the key autophagy protein LC3B, as well as some other autophagy-related proteins (increase in Beclin-1 and decrease in P62). In order to further explore the mechanism that ARG passed initiating autophagy to inhibit cell growth, we further found by Western blotting that AKT and mTOR phosphorylation proteins (P-AKT, P-mTOR) were reduced after ARG treatment, and we used AKT agonists to rescue, and the phosphorylated proteins of AKT and mTOR increased, and we found that the autophagy-related proteins were also reversed. And interestingly, the protein of apoptosis was also reversed along with autophagy. Conclusions. We thought ARG inhibited the proliferation of glioma cells by inducing autophagy and apoptosis through the AKT/mTOR pathway.

Abstract:
RÉSUMÉ Des populations d'aulne vert (Alnus crispa (Ait.) Pursh) de la région de la rivière aux Feuilles (58°15' N, 72° O) sont particulièrement bien développées sur les versants bien drainés exposés au sud et situés au-delà de la limite locale des forêts. Ces populations correspondent à une importante expansion de l'espèce surtout au cours du XXe siècle, entre 1920 et 1960. L'essentiel des populations d'aulne vert sont apparues après 1920, à la suite de la germination des graines sur les plaques de sol nu d'origine périglaciaire (ostioles, traînées de gélifluction, etc.). Au cours de la succession, la végétation lichénique et arbustive rase d'origine s'est graduellement transformée, en quelques décennies, en une végétation clairsemée de sous-bois sous le contrôle d'une épaisse litière produite par l'aulne. Le développement graduel des populations d'aulne a aussi causé des changements sensibles dans les sols de ces milieux: épaississement de l'horizon organique à la suite de fortes accumulations de feuilles d'aulne, augmentation du pourcentage de la matière organique, diminution du rapport C/N, augmentation de la CEC, des bases totales et du contenu en azote, et diminution du pH. Au cours de cette séquence évolutive, la régénération végétative devient virtuellement le seul mode de reproduction de l'aulne. Cette situation de l'aulne vert à la rivière aux Feuilles a été retrouvée ailleurs dans l'ensemble de l'Hémi-arctique et indique 1) que l'espèce répond aux changements climatiques qui caractérisent cet important biome de la péninsule du Québec-Labrador et 2) que le phénomène est général dans cette région et mérite ainsi d'être étudié plus en détail pour des fins d'interprétation paléoécologique et palynologique.

Abstract:
Arctiin, a lignan glycoside, is isolated from Arctium lappa L. The anticancer effects of arctiin have been demonstrated in several studies. However, no research has been conducted on the anti-migration effect of arctiin in cervical cancer cells. The present study examined the effects of arctiin on cervical cancer cells and investigated the possible molecular mechanism. We demonstrated that arctiin exhibited low cytotoxicity and significantly inhibited cell migration and invasion in human cervical cancer cells. The S100A4 protein expression and mRNA levels were significantly reduced in HeLa and SiHa cells with arctiin treatment. Furthermore, silencing S100A4 by using small interfering RNA reduced cell migration, while overexpression of S100A4 mitigated the migration inhibition imposed by arctiin in cervical cancer cells. Western blotting revealed that arctiin significantly reduced phosphoinositide 3-kinase (PI3K) and phosphorylation of Akt in cervical cancer cells. Moreover, selective Akt induction by an Akt activator, SC-79, reverted cervical cancer cell migration and S100A4 protein expression, which were reduced in response to arctiin. Taken together, these results suggest that arctiin inhibits cervical cancer cell migration and invasion through suppression of S100A4 and the PI3K/Akt pathway.

Abstract:
As a highly aggressive form of human cancer, melanoma is prone to metastasis, leading to 75% of all skin cancer deaths. The 5-year-survival rate of melanoma is below 20%. Therefore, new therapies for melanoma are urgently needed. Burdock (Arctium lappa L) root - known for its antitumor, antioxidant, anti-inflammatory, antiviral, neuroprotective, and endoplasmic reticulum stress regulatory effects - was evaluated for its effects on the proliferation and apoptosis of melanoma cells and its possible mechanism. The results show suppression of the proliferation and stimulation of apoptosis of A375 cells in vitro. Additionally, it suppressed the PI3K/AKT pathway in A375 cells. These data suggest burdock (A. lappa L) root preparation as a promising drug for the treatment of melanoma.

Abstract:
This article reveals that John Milton employed an allusion to the aurora borealis in book 6 (79–83) of Paradise Lost, unrecognized in more than three centuries of scholarly analysis. Two other likely allusions, and one certain, to the aurora have also been identified. This research casts doubt on the long-held belief, made popular by the astronomer Edmund Halley (1656–1742), that no notable aurora was visible in England in the seventeenth century. After examining an overlooked note by the English historian William Camden (1551–1623), this article explores the possibility that Milton actually saw an aurora. A solution is also presented here to the long-standing conundrum of the comet near the “Arctic” constellation Ophiuchus in book 2 (707–11) of Paradise Lost. Cet article révèle que John Milton fait allusion à une aurore boréale au sixième livre (79–83) de Paradise Lost, allusion qui est restée ignorée pendant plus de trois siècles de lectures savantes. Une autre allusion à une aurore boréale, ainsi que deux autres, probables, ont été identifiées. Cette recherche remet en question l’opinion tenue de longue date, et circulée par l’astronome Edmund Halley (1656–1742), qu’aucune véritable aurore boréale ne put être observée en Angleterre au dix-septième siècle. Grâce à l’analyse d’une note, longtemps négligée, de l’historien anglais William Camden (1551–1623), cet article explore la possibilité que Milton ait pu réellement observer une aurore boréale, ce qui pourrait alors résoudre l’énigme de la mention, au deuxième livre du Paradise Lost (707–711), d’une comète près de la constellation « arctique » Ophiuchus.

Abstract:
Cette recherche doctorale examine les pratiques figuratives, les représentations symboliques et les enjeux socio-culturels des arts graphiques inuit dans les communautés de Kinngait (Cape Dorset) et de Pangniqtuuq (Pangnirtung) au Nunavut (Arctique canadien). Les notions de dessin (titiqtugaq-) et de parole (uqaq-) se placent au centre de la démarche qui est guidée par une approche interdisciplinaire, dans la perspective d’une ethnohistoire de l’art du dessin inuit. Trois parties structurent la démonstration. La première explore les configurations de la pensée inuit associées aux concepts d’art graphique, de représentation visuelle et de créateur, à partir de leur expression linguistique (chapitre II). Puis, une ethnographie de la scène artistique locale présente le dessin et les activités socio-économiques qui lui sont associées autour de la question du statut de l’artiste (chapitres III et IV). La deuxième partie envisage la figuration en rapport à la parole, à partir de la cosmogénèse et des techniques graphiques anciennes (chapitre V). Elle s’intéresse ensuite aux interactions entre le dessin et la parole sur un plan symbolique : dans le dessin, les pensées et les mots sont mis en actes (chapitres VI et VII). La dernière partie de la thèse définit l’art comme un élément de la dynamique socio-culturelle et politique des Nunavummiut. Le recours au dessin dans le cadre de projets communautaires est étudié à partir d’exemples récents (chapitre VIII), avant d’être replacé au centre des dynamiques relationnelles et des échanges socio-cosmiques dans une dimension ontologique (chapitre IX)
This doctoral research examines the themes of figurative practices, symbolic representations and the socio-cultural stakes specific to Inuit graphic arts in the communities of Kinngait (Cape Dorset) and Pangniqtuuq (Pangnirtung) in Nunavut (the Canadian Arctic). The notions of drawing (titiqtugaq-) and of speech (uqaq-) are central to the thesis, which is guided by an interdisciplinary approach within the perspective of ethno-history of Inuit sketch art. The thesis is organized into three parts. The first explores the configuration of Inuit thought associated with the concepts of graphic art, visual representation and creation, through their linguistic expression (Chapter II). In addition, ethnography of the local art scene looks at drawing and the socio-economic activities that are associated with it, in connection with the status of the artist (Chapters III and IV). The second part looks at figuration in relation to power words, from cosmogenesis and ancient graphic techniques (Chapter V). With this in hand, the second part then looks at the interactions between drawing and speaking from a symbolic perspective: through drawings, the thoughts and words are put into action (Chapters VI and VII). The last part of the dissertation continues the analysis by defining art as part of the socio-cultural and political dynamics of the Nunavummiut. Recourse to drawing, as a community project, is studied with reference to recent examples (Chapter VIII), prior to being placed, within an ontological dimension, at the centre of relational and socio-cosmic exchange dynamics (Chapter IX)

Abstract:
Abstract Plants in the boreal forest are an important component of the ecosystem for two main reasons. First, the plants as vegetation form the physical surroundings for both herbivores and carnivores and are the basis of the physical structure of the community. Second, as primary producers, they provide the energy and nutrients to the herbivores on which higher trophic levels depend. Therefore, understanding the factors that limit the quantity and the quality of plants is fundamental. Our studies focus on the herbaceous vegetation but primarily on two grasses, Festuca altaica and Calamagrostis lapponica, which dominate small meadows scattered throughout the white spruce forest, and on the four herbs, Lupinus arcticus, Anemone parviflora, Mertensia paniculata, and Achillea millefolium var. borealis, which are relatively abundant in the forest understory (see the appendix fol­ lowing this chapter). These plants provide a source of high-quality food to the herbivores. Soil nutrients, especially nitrogen, often limit the productivity of boreal forest vegeta­ tion (Bonan and Shugart 1989) and may control vegetation standing crop. Plants differ in their abilities to respond to increased nutrient levels, and community composition usually changes after fertilization as more competitive species begin to dominate. The nutrient availability level also influences a species’ ability to produce defensive chemical com­ pounds against herbivory (Coley et al. 1985) and the ability to regrow after herbivory (Hilbert et al. 1981, Maschinski and Whitham 1989). Conversely, herbivory may have a direct effect on vegetation quantity and quality. Herbivory has long been known to influence species composition in some plant communities (Huntly 1991) due to differential plant palatability and differences in plants’ abilities to tolerate herbivory. Many plants pro­ duce defensive chemical compounds in response to herbivory (Palo and Robbins 1991, Tallamy and Raupp 1991). The snowshoe hare has distinct preferences among the summer forage species available in the boreal forest (Bryant et al. 1991).

Abstract:
Abstract This arcticle highlights the importance of a systematic step change approach to the formulation of completion fluids in the Llanos Basin (LLAB), Colombia, when formation-freshwater is to be used as control - completion (C&C) fluid. The results demonstrate that the process used reduced the formation damage statistics from 41% of the wells drilled to only 16%, boosting production and establishing a best practice for future drilling and completion (D&C) campaigns in the region. An initial sample of 19 wells was considered to evaluate the damage caused by using formation-freshwater as C&C fluid. Formation-freshwater was selected only considering the fluid density (wellbore pressure), ignoring the negative effects it can have on formation damage. 41% of the wells were damaged, as evidenced by pressure build up. Some of the main damages on the pay-zone in an oil well are due to emulsion blocking, change in wettability, swelling and migration of clays, incompatibility of fluids, and scale formation. A detailed design of completion fluids has a positive influence over well productivity by mitigating formation damage before starting the production stage. The methodology used was aimed at designing the C&C fluid through a step-by-step approach, consisting of: 1) Laboratory tests supported with mineralogical data and oil and formation water properties and 2) Physical-chemical analysis of reservoir fluids and water for mixing purposes. The process involved testing different formulations and then their implementation in the field. The initial tests were conducted in a total of 5 wells in 4 fields. Changes were identified in the formulation to achieve optimal fluid design for each field and then the selected fluid was extended to a total of 24 wells. This was the first time a thoroughly designed completion fluid was used in the region. The results point towards the need to include surfactants, mutual solvents, and brines to substantially reduce formation damage. The application of new completion fluids enabled the operational teams to optimize the process by steps. The implementation of customized completion fluid reduced the formation damage as evidenced through productivity analyses and pressure build up tests. Only 16% of the wells presented formation damage. The process applied to reduce formation damage of the Llanos Basin led to a systematic approach for the analysis stage, which may be applied in other areas, where the utilization of formation-freshwater is an issue. The particularly short time frames and best practices derived from the learning curve of this case are worth to be shared with other operators.
