Texto completo da fonteThe aim of this essay was to show that the theme of how a troubled young man in a crisis who is saved by the love of a little girl is central in J.D Salinger’s novel The Catcher in the Rye, as well as in his short story “For Esmé - with Love and Squalor”. Furthermore, the argument was that there is a strong kinship between the protagonists of both stories as well as the little girl, thereby supporting the existing opinion of critics that Salinger is a writer who returns to favored themes and characters.

Texto completo da fonteThe genus Squalus Linnaeus, 1758 (Elasmobranchii: Squalidae) comprises a group of cosmopolitan sharks species with a high taxonomic complexity due to difficulties in morphologically differentiating its component species, many of which must be taxonomically reviewed. Currently, there are 24 valid species of Squalus which have been divided into three species-complexes according to morphological similarity: the S. acanthias group, the S. megalops group, and the S. mitsukurii group. Loss of type-specimens of nominal species, the propagation of erroneous identifications in the literature, and difficulties in obtaining representative series for comparison are secondary challenges that impede a global taxonomical revision of Squalus. This problem applies very clearly to species from the Southwestern Atlantic Ocean as well, including species that occur off Brazil, mostly because of a complete lack of detailed morphological revisions. Following a current global tendency, a regional taxonomic review of Squalus was conducted in order to investigate which species are valid in the Southwestern Atlantic Ocean as well elucidate which diagnostic morphological characters can be efficiently used to separate species. The present proposal aimed to conduct a taxonomic review of the genus Squalus from the Southwestern Atlantic Ocean through a comparative and detailed analysis of external and skeletal morphology from representative series of specimens of Squalus from the region. The results obtained validate four available nominal species, Squalus acanthias, S. blainvillei, S. megalops, S. cubensis, and also includes characterization of Squalus sp. The results are based on aspects of external morphometry, dentition, color pattern, meristic data, and characters from the skeleton (primarily neurocrania) which were illustrated and compared with specimens of Squalus from other geographic regions.

Texto completo da fonteDans cette étude, trois différents enzymes protéolytiques, soit α-chymotrypsine, trypsine, et papaine, ont été utilisés pour hydrolyser des échantillons de peau provenant d'aiguillat commun (Squalus acanthias). Les activités antioxidante, antimicrobienne et inhibitrice ont été mesurées sur les hydrolysats ainsi obtenus. Les réactions protéolytiques ont été conduites en traitant les échantillons de peau avec une concentration dènzyme de 1 % durant 4 heures à 37oC, suivi d'ultrafiltration sur membranes 10 kDa. La capacité antioxidante des hydrolysats par α-chymotrypsine (CPH), basé sur les valeurs IC50 a été calculée comme suit : 0.095 mg/mL, 0.116 mg/mL et 0.349 mg/mL, respectivement envers l'anion superoxide, le radical hydroxyle, et pour le pouvoir de chélation minérale. Ces mêmes valeurs dans le cas des hydrolysats par trypsine (TPH) étaient respectivement de 0.198 mg/mL, 0.186 mg/mL et 0.211 mg/mL. Enfin, pour les hydrolysats par papaïne (PPH), des résultats correspondants de 4.388 mg/mL, 0.096 mg/mL et 0.286 mg/ml ont été mesurés. L'atteinte d`un pouvoir réducteur de 0.5 a exigé les concentrations suivantes de chaque hydrolysat: 0.940 mg/mL de PPH, 1.083 mg/mL de CPH et 3.70 mg/ml de TPH. Nos essais initiaux d`activité antimicrobienne DH5- E.coli, Lactococcus lactis et Bacillus subtilis avec polymyxine B comme témoin positif, n`ont mis aucune activité en évidence. En présence de chacun de ces trois hydrolysats, le taux de survie des bactéries probiotiques (Lactococcus lactis et Bacillus subtilis) a augmenté par rapport au témoin négatif. Pour une concentration de 0.35mg/mL le CPH a montré un taux d`inhibition de 65% envers la lipase pancréatique du porc, alors que TPH et PPH ont plutôt favorisé l`activité de cet enzyme. A 40μg/mL, le % d`inhibition de l'α-chymotrypsine observé pour ces trois hydrolysats était de 32.5% (CPH), 16.4% (TPH) et 8.5% (PPH). La présente étude a démontré que les hydrolysats protéiques obtenus à partir de la peau d`aiguillat par voie enzymatique possèdent des propriétés antioxidantes et inhibitrices, de même qu'une capactié à augmenter le taux de survie de certaines bactéries probiotiques. Des travaux supplémentaires sont requis afin de caractériser les peptides constitutifs de ces hydrolysats et également leurs effets antimicrobiens spécifiques; ceci permettra dèn valider le potentiel comme bioadditifs en transformation alimentaire.

Texto completo da fonteNo período de março de 1997 a agosto de 2002, 623 exemplares de Squalus spp, foram capturados pelos Barco de Pesquisa Prof Martins Filho (LABOMAR/UFC), Barco de Pesquisa Natureza (CEPENE/IBAMA) e Barco de Pesquisa Sinuelo (Dept. Pesca/ UFRPE), vinculados ao programa REVIZEE. A área de atuação dos barcos localizou-se entre as latitudes de 00 a 150 S e longitudes de 300 a 450 W, utilizandose como aparelhos de pesca o espinhel e armadilhas de fundo, em profundidades aproximadas de 50 a 700 m. Os espécimens do gênero Squalus possuem características distintas, como: olhos grandes, 1 espinho nas nadadeiras dorsais e ausência de nadadeira anal, sendo os mesmos vivíparos aplacentários e, como a maioria dos elasmobrânquios, apresentam baixa fecundidade e maturação sexual tardia, tornando-se assim de extrema importância o estudo acerca da sua biologia reprodutiva, a fim de que se possa garantir em bases sustentáveis uma exploração adequada desse recurso. Do total de 93 S. asper analisados, 43 eram fêmeas e 50 machos, com CT variando de 51,0 cm a 123,5 cm. Das fêmeas, 29 encontravam-se juvenis, 6 pré-ovulatórias, e 8 prenhes. As fêmeas juvenis apresentavam as glândulas oviducais e os úteros filiformes e os ovários não diferenciados do órgão epigonal, enquanto as pré-ovulatórias encontravam-se com o maior folículo medindo entre 2,7 e 4,0 cm de diâmetro e os úteros dilatados. Nas fêmeas prenhes o maior folículo ovariano (MFO) media 1,9 cm de diâmetro, enquanto os embriões variaram de 17,0 e 23,0 cm CT. Dos 50 machos, 10 eram juvenis, apresentando o clásper flexível, 6 sub-adultos e 34 adultos, com os cláspers bem calcificados e os testículos bastantes desenvolvidos, apresentando, também, grande volume de líquido seminal nas ampolas dos ductos deferentes. Os machos alcançam a maturação sexual próximo a 95,0 cm, enquanto que as fêmeas, com 110,0 cm. Do total de 206 S. mitsukurii analisados, 37 eram machos, com comprimento total (CT) variando de 56,0 a 73,0 cm de comprimento total (CT), peso variando entre 559,9 e 1760 g, onde 4 eram juvenis, 8 subadultos e 25 adultos. Entre esses machos o clásper variou de 1,2 a 6,0 cm e o peso do testículo apresentou uma variação entre 1,0 e 10,5 g. As fêmeas amostradas totalizaram 169 exemplares, com CT de 50,5 a 94,3 cm, peso entre 575,0 e 4470 g, sendo 61 juvenis, 26 pré-ovulatórias I, 13 pré-ovulatórias II, 25 em início de gestação, 38 prenhes e 6 a termo. Dentre os 318 embriões encontrados nas fêmeas prenhes, foi possível a sexagem de 271, dos quais 132 eram machos e 139 eram fêmeas. Por fim, os 324 exemplares restantes eram Squalus sp com 275 fêmeas e 49 machos e CT variando de 31,0 a 81,2 cm e peso entre 115,0 e 3.280,0 g. Das fêmeas amostradas 52 eram juvenis, 47 pré-ovulatória, 50 em início de gestação, 17 prenhes e 2 pós-parto. O MFO dessas fêmeas variou de 0,1 a 4,4, glândulas oviducais apresentaram uma largura entre 0,9 e 1,9 e úteros com 1,0 a 6,9 cm de largura. As fêmeas prenhes possuíam 420 embriões com CT entre 2,4 e 22,5 cm, com proporção sexual de machos para fêmeas de 1:1,22. Os 49 machos analisados, 3 eram juvenis, 6 subadultos e 40 adultos,com CT entre 31,0 e 64,5 cm, com peso dos testículos variando entre 0,5 e 5,5 g e os indivíduos adultos com clásper medindo entre 2,5 e 5,5 cm

Texto completo da fonteLa littérature en études cinématographiques présume que les studios indépendants de films à petit budget, plus connus sous le vocable Poverty Row, prennent leur origine aux débuts du cinéma sonore, afin de bénéficier de la popularité croissante des projections à programme double. Cependant, l'émergence des studios indépendants de Poverty Row est en fait le résultat d'interactions complexes entre les studios naissants d'Hollywood et la production cinématographique indépendante durant la fin des années 1910 et durant les années 1920. À mesure que les studios hollywoodiens augmentent leur production, tout comme leurs réseaux de distribution et leurs circuits de projection, les producteurs indépendants restés en dehors du système de studios, deviennent de plus en plus marginalisés et coupés des secteurs les plus profitables de la projection de films. À la fin des années 1920, la production indépendante non-hollywoodienne en est réduite à des films d'action de série B (des westerns, des films d'aventure ou des séries) comptant de maigres profits réalisés dans des marchés de petites villes et villages. Avec les difficultés économiques causées par la Dépression, les studios hollywoodiens dominants sont forcés de couper la production de leurs films à petit budget, permettant ainsi involontairement aux compagnies de production indépendante, aujourd'hui connues sous le nom de Poverty Row, d'augmenter leur création.Cette thèse porte sur l'histoire des studios indépendants de Poverty Row des années 1930, depuis l'introduction du son dans les films, jusqu'à la fin de ces compagnies indépendantes en 1940. À travers une recherche d'archives et des analyses textuelles, ce projet documente le sort déclinant de la production indépendante de films et contraste ce déclin avec la montée des studios d'Hollywood, et la transformation graduelle de la production cinématographique indépendante de l'époque muette vers les studios de Poverty Row. De plus, cette thèse analyse comment le positionnement résiduel de Poverty Row à l'intérieur du champ du cinéma américain des années 1930 détermine sa relation avec les importants studios hollywoodiens dominants, tout comme sa production cinématographique distinctive. Même si la production indépendante de Poverty Row a lieu en même temps que le cinéma hollywoodien classique, elle n'a pas participé directement aux innovations artistiques et technologiques du modèle classique de production de films hollywoodiens. À la place, ces productions à petit budget ont perpétué l'esthétique établie durant la période muette au sein du cinéma sonore. En conséquence, les films produits par les studios indépendants de Poverty Row durant les années 1930 démontrent des éléments persistants du cinéma muet, incluant les genres, les styles de film et des représentations démodées de la modernité. Cette perpétuation d'un cinéma du passé au sein du cinéma sonore définit non seulement la production des films de Poverty Row, elle détermine également sa relation avec les importants studios d'Hollywood et sa position à l'intérieur de l'industrie du film des années 1930.

Texto completo da fonteObjectif: L'invasion du tissu osseux est un problème majeur dans le traitement des cancers de la tête et du cou, cependant les mécanismes d'interactions entre le carcinome de cellules de squamous oral (OSCC) et les cellules du tissu osseux sont mal compris. Nous avons posé comme hypothèse que les cellules tumorales peuvent stimuler directement le phénomène d'ostéoclastogenèse. Méthodes: Deux différentes populations cellulaires de la lignée OSCC furent utilisées: les cellules BHY ayant un potentiel de colonisation du tissu osseux et les cellules HN ayant un potentiel métastatique mais non colonisant. Ces deux lignées cellulaires ont été cultivées et le milieu de culture conditionné (CM) a été collecté. La formation de cellules ostéoclastiques à partir de cellules de la lignée monocytaire de souris RAW 264.7 a été évaluée. Résultats: Une augmentation significative du phénomène d'ostéoclastogenèse d'un facteur 2 à 6 fut observée lors d'une activation des cellules RAW 264.7 avec RANKL suivit d'un traitement avec BHY-CM. De plus, la survie des cellules ostéoclastiques matures était favorisée en présence de BHY-CM uniquement. L'utilisation d'inhibiteurs pharmacologiques nous a permis de mettre en évidence que la stimulation du phénomène d'ostéoclastogenèse induite par BHY-CM est médiée par les voies de signalisations PKC/ERK/p38 et PI3K/AKT/mTOR. Conclusion : Les cellules OSCC produisent des facteurs solubles stimulant la formation d'ostéoclastes à partir de précurseurs activées par RANKL. Les facteurs dérivés de tumeurs agissent en stimulant les voies de signalisation ERK1/2 et p38 dans les précurseurs ostéoclastiques.

No presente estudo são definidos três grupos de espécies de Squalus para o litoral brasileiro, e é feita uma caracterização do grupo megalops. A partir da análise da morfologia externa (formato das nadadeiras pélvicas, comprimento do espinho das nadadeiras dorsais em relação a altura das nadadeiras e posição das nadadeiras pélvicas em relação as nadadeiras dorsais), dentículos dérmicos, condrocrânio, coluna vertebral, dentição e mixopterígios, verifica-se que o Squalus megalops do sul do Brasil (sensu Vooren, 1992), o Squalus cubensis do sudeste do Brasil (sensu Figueiredo, 1977) e Squalus sp. do sudeste (sensu Figueiredo, 1981) constituem uma única espécie, que foi denominada Squalus sp. do grupo megalops. Os caracteres que se mostraram mais importantes para a definição da espécie foram: morfologia externa, dentículos dérmicos, condrocrânio e mixopterígios. O estudo indica ainda que outras duas formas ocorrem na costa brasileira: Squalus acanthias e Squalus sp. do grupo blainvillei.
Three species groups of Squalus from the Brazilian coast are defined and the megalops group is characterized. According to analysis of external morphology (pectoral fins shape, dorsal fins spines length in comparison with the high of these fins and position of pelvic fins in comparison with dorsal fins), dermal denticles, chondrocranium, vertebral column, dentition and claspers, it is demonstrated that southern species Squalus megalops (sensu Vooren, 1992), southeastern Squalus cubensis (sensu Figueiredo, 1977) and Squalus sp. (sensu Figueiredo, 1981 ), from central and southern Brazil, represents a single species, wherein Squalus sp. of the megalops group. The most important characters to define this species were external morphology, dermal denticles, chondrocranium and claspers. The study also indicated two aditional species occurs in Brazilian waters: Squalus acanthias and Squalus sp. of the blainvillei group.

Texto completo da fonteThis project explores species boundaries, coevolution, biodiversity, parasite life cycles, and ecology using the cestode (tapeworm) fauna parasitizing the spiny dogfish, Squalus acanthias, and several of its close relatives. One of the aims was to verify the species identity of all the shark specimens from which cestodes were collected. Chapter 1 details use of the elasmobranch "barcoding" gene, NADH2, to verify host identifications, as well as to raise doubt about the wisdom of recognizing the Black Sea population of S. acanthias as a distinct subspecies. Chapter 2 examines diversity in the monotypic cestode genus, Trilocularia, throughout the widespread anti-tropical distribution of S. acanthias (i.e., the North and South Pacific, the North Atlantic, and the Black Sea), and in its congeners. An integrative approach, including morphological (i.e., light microscopy, histology, and scanning electron microscopy) and molecular methods (i.e., 28S, ITS1, 16S genes), was employed. Results reveal a large amount of undiscovered diversity in this genus and suggest that species of Trilocularia may be undergoing speciation more rapidly than their hosts. Chapter 3 describes one of the new species discovered, Trilocularia eberti n. sp. from S. cf. mitsukurii, and provides a prototype for future descriptions of species in this genus. Chapter 4 investigates microthrix variation in Trilocularia from the stomach and the spiral intestine of S. acanthias off Rhode Island. Results suggest that variation seen within a host individual is likely due to developmental changes rather than species differences. Chapter 5 aims to further the understanding of cestode infections in a marine environment through space and time by examining seasonal infection parameters in the cestode community of S. acanthias from Rhode Island across three years. While some general trends may be maintained across disparate localities, spatial variation is likely due to differences in accessibility to intermediate hosts and host diet across sites. The knowledge gained from understanding cestode infections in the vast ocean environment allows us to speculate about the factors driving fluctuations in parasite infections in elasmobranchs.

Texto completo da fonteOver the last century, an overall depletion of the marine resources has been documented in many oceans and in particular in the Mediterranean Sea. This depletion has been driven by many anthropogenic activities among which fishing activities have one of the strongest direct impacts. The elasmobranch species are among the most important apex- and meso- predators in the food web, contributing to the balance and functioning of the marine ecosystems. The Mediterranean Sea hosts a wide diversity of elasmobranchs that live in all marine ecosystems. Typically, the elasmobranch life cycle consists in a slower growth rate compared to other marine organisms. This also implies that the time to reach sexual maturity at which an organism can reproduce for the first time takes much longer than other marine species. Within their life cycle, elasmobranch species often require specific habitats to complete their reproduction or foraging needs and no-random choice leads to a specific propriety in the use of space as for instance philopatry, site fidelity and natal homing. Scientific research has reported how essential habitats, used in different stages of their life cycle and across generations, can be subjected to high fishing pressure, especially the coastal areas of several subbasins like the Adriatic Sea where one of the highest fishing pressures is found. As the direct consequence of long period of overfishing, many elasmobranch species have been threatened by extinction. The current scenario in the Mediterranean Sea calls for appropriate management and conservation strategies directed to the commercially-relevant and endangered elasmobranch species. The knowledge of the use of space of elasmobranch throughout the year and among life stages could greatly contribute to the definition of a spatially explicit management which has resulted to be successful in other oceans to sustainably manage the elasmobranch fishery, thus halting or reversing the declining scenario. With the multidisciplinary approach applied to accomplish this PhD thesis, the achieved results have shed some light to define critical periods and locations in which commercially relevant elasmobranchs like the smooth hounds (Mustelus spp.) or endangered large coastal shark like the sandbar shark (Carcharhinus plumbeus) complete critical steps of their life cycle like birthing, mating and growing using nursery area for foraging purposes. Such multidisciplinary approach could be paramount to provide missing information of elasmobranch species in the Mediterranean Sea and support the establishment of tailored management towards elasmobranch conservation.

Texto completo da fonteIn this thesis, we use the well-documented 10-11 June 1985 squall line as a test bed to examine the appropriate incorporation of various physical representations and their coupling with RFE's model components. It is demonstrated through a series of sensitivity studies that the operational prediction of squall lines can be improved if more realistic model physics, reasonable initial conditions, and high resolution are used. It is shown that subgrid-scale moist convection and grid-scale moist physics must be adequately treated in order to reproduce the internal structures of the squall line.
Then, the improved version of the RFE model is used to study the role of gravity waves in the development of a prefrontal squall line associated with the 14 July 1987 Montreal flood. It is found that the gravity waves and convection propagate in a "phase-locked" manner and that the wave-CISK mechanism accounts for the maintenance and intensification of the system. It is also found that frontogenetical processes and release of conditional symmetric instability are responsible for the development of a trailing stratiform rainband associated with the July 1987 Montreal flood. Numerous sensitivity experiments are conducted, and they show that the meso-$ beta$-scale structures and the wave-convection system are very sensitive to the interaction of the parameterized convection with grid-scale physical processes.
In the last part of the thesis, the along-line variability 26-27 June 1985 squall line during PRE-STORM is examined. It is found that the three-dimensional structures of the squall's circulations are determined by both a large-scale trough and convectively generated disturbances. In particular, it is shown that rear inflows in the stratiform region tend to be more intense to the south of the mesolow and neat the base of the large-scale trough.

Texto completo da fonteIt is found that the squall line is initiated ahead of a weak surface front with the aid of baroclinic forcing. Once initiated, the squall system is more or less driven by the interaction of convectively generated circulations with the potential unstable environment ahead. The baroclinic forcing only provides a favorable environment for the evolution of the squall system. As the squall system rapidly intensifies and accelerates eastward, it enhances the larger-scale baroclinicity and produces a phase-lag between the pressure and thermal waves so that the baroclinic environment is more favorable for surface cyclogenesis.
To isolate the roles of moist convection in the surface cyclogenesis, a "moist" and a "dry" simulation are compared. It is found that in the absence of moist convection the model could also produce a surface cyclone, but with much weaker intensity, much smaller extent and slower displacement. The effects of moist convection are shown not only to increase the upper-level and decrease the lower-level height of isobaric surfaces, but also to condition the baroclinic environment by increasing the phase lag between the pressure and thermal waves and enhancing the large-scale baroclinicity.

Texto completo da fonteINTRODUZIONE La fibrosi polmonare idiopatica (FPI), caratterizzata morfologicamente dal correlato patologico di polmonite interstiziale usuale (UIP), rappresenta una malattia ad eziologia sconosciuta, ad andamento progressivo e prognosi infausta. Gli elementi anatomo-patologici cardine sono il danno/attivazione epiteliale, la formazione di foci fibroblastici/miofibroblastici ed il rimodellamento della matrice extracellulare. La teoria patogenetica più accreditata attribuisce un ruolo determinante alla disfunzione epiteliale alveolare. Il danno epiteliale ed i successivi meccanismi deregolati di riparo portano al rilascio di citochine pro-fibrogenetiche (come il TGF-b1) con conseguente attivazione e proliferazione di cellule mesenchimali. Di conseguenza, l’instabilità epiteliale sembra un elemento cruciale nello sviluppo e progressione della malattia, inclusa la trasformazione neoplastica. Pochi markers molecolari sono stati studiati e descritti fino ad ora nella FPI, per meglio chiarire i meccanismi patogenetici della malattia. Lo squamous cell carcinoma antigen (SCCA) è un inibitore delle serin proteasi (serpine) fisiologicamente presente nell’epitelio squamoso normale e specificamente espresso dalle cellule displastiche e neoplastiche epiteliali di varia origine, più spesso nei tumori a cellule squamose. Non sono ancora disponibili informazioni specifiche sulla sua espressione nella FPI. MATERIALI E METODI In questo studio abbiamo analizzato l’espressione di SCCA e TGF-b1 in tessuto polmonare ottenuto da biopsie chirurgiche di 22 pazienti affetti da FPI in stadio clinico iniziale (Gruppo A), in polmoni nativi di 48 pazienti con malattia end-stage e sottoposti a trapianto di polmone (Gruppo B) e in 20 polmoni controllo (Gruppo C, 10 polmoni normali ottenuti da donatori cadaveri, 10 polmoni di pazienti affetti da altre malattie interstiziali). Abbiamo inoltre condotto uno studio in vitro utilizzando pneumociti della linea A549, per investigare il rapporto tra la produzione di SCCA e l’espressione di TGF-b1. L’espressione di SCCA e TGF-b1 nelle cellule epiteliali è stata valutata con tecniche di immunoistochimica e reazione a catena della polimerasi-trascrizione inversa (RT-PCR). La produzione di TGF-b1 nei pneumoniti A549 incubati a diverse concentrazioni di SCCA è stata verificata con real time PCR. La valutazione quantitativa immunoistochimica di SCCA e TGF-b1 è stata eseguita in ciascun campione contando almeno 500 cellule cuboidali. Una valutazione quantitativa dei differenti parametri patologici (fibrosi, foci fibroblastici e honeycombing) è stata eseguita ugualmente in ciascun campione. I dati clinici, inclusi la funzione respiratoria e i parametri cardiovascolari sono stati correlati ai dati patologici. Nel Gruppo A i test di funzionalità polmonare sono stati ripetuti a 8-12 mesi dalla biopsia. RISULTATI L’espressione di SCCA nelle cellule epiteliali alveolari era presente nei pazienti con FPI, mentre era assente nei controlli. Nel Gruppo A l’SCCA era correlato positivamente con l’estensione dei foci fibroblastici (r=0.49, p=0.02), l’espressione di TGF-b1 (r=0.78, p<0.0001) e con il declino della DLCO al follow up (r=0.59, p=0.01). L’esperimento in vitro ha dimostrato che l’incubazione di pneumociti con SCCA induceva l’espressione di TGF-b1, con un picco a 24 ore. Nel Gruppo B i valori di SCCA e TGF-b1 erano elevati e correlati positivamente (r=0.45, p<0.001), mentre vi era una correlazione inversa tra SCCA e DLCO (r=-0.43, p=0.005) e TGF-b1 e DLCO (r=-0.42, p=0.04). Tra le cellule epiteliali alveolari metaplastiche, abbiamo riscontrato una diversa espressione di SCCA tra le cellule cuboidali, bronchializzate e squamose, con una crescente espressione per le squamose che inoltre presentavano un maggior grado di displasia. CONCLUSIONI La over-espressione di SCCA e TGF-b1 nell’epitelio alveolare corrobora l’ipotesi che una alterata rigenerazione epiteliale alveolare e una secrezione anormale di citochine sono elementi importanti nella patogenesi del rimodellamento e della fibrosi della FPI. L’SCCA potrebbe avere un duplice ruolo influenzando la proliferazione epiteliale (azione autocrina) e promuovendo la fibrosi/proliferazione dei fibroblasti attraverso lo stimolo alla maggior secrezione di TGF-b1. L’SCCA potrebbe essere considerato un marker potenziale di attività della malattia essendo strettamente correlato con la perdita di funzione polmonare.

A formação de tornados é um fenômeno pouco frequente no Centro-Oeste do Brasil. O registro de um tornado em Brasília-DF em 01 de outubro de 2014 evidencia a importância da utilização de métodos que permitam compreender melhor os vários mecanismos atmosféricos dominantes em episódios de tempo severo e monitorar esse fenômeno meteorológico com alto potencial de destruição. Este estudo teve como propósito analisar a estrutura vertical da atmosfera que prevaleceu no desenvolvimento de condições atmosféricas adversas e identificar parâmetros convectivos adequados para determinação de padrões atmosféricos que favoreceram o desenvolvimento de tempo severo. A técnica estatística Análise de Componentes Principais (ACP), índices de instabilidade e imagens de radar meteorológico foram os principais métodos de análise utilizados. Os resultados mostram que a combinação entre o alto grau de instabilidade atmosférica, temperaturas elevadas e vento intenso acompanhado de rajadas foi determinante para o desenvolvimento do tornado. Entretanto, os valores dos índices de instabilidade diferem dos limiares normalmente utilizados como indicadores da formação de tornados. Linhas de instabilidade em forma de arco (“bow echoes”) detectadas pelo radar durante o período de chuva intensa com danos em superfície são os indícios mais fortes do tornado que atingiu a região. Registros fotográficos de linhas de energia, telhados, árvores e carros danificados pelo vento (95 km/h) também são apresentados.
The frequency of tornado formation in Central-West Brazil is low. A tornado observed in Brasília-DF on 01 October 2014 highligths the importance of using methods that allow a better understanding of the various atmospheric mechanisms that dominate in severe weather episodes, and the monitoring of this meteorological phenomenon with high destructive potential. The aim in this study was to analyze the vertical structure of the atmosphere that dominated the development of adverse atmospheric conditions and to identify convective parameters that are adequate for determining atmospheric patterns that favor severe weather development. The statistic technique Principal Component Analysis (PCA), instability indices and meteorological radar images were the main analysis methods employed. The results show that the combination of high degree of atmospheric instability, high temperatures and intense wind with gusts was determinant for tornado development. However, values of the instability indices differ from those normally used as indicators of tornado formation. Arc-shaped squall lines (“bow echoes”) detected by radar during the period of intense rainfall with damages at the surface are the strongest evidence of the tornado that hit the region. Photos of power lines, roofs, trees and cars damaged by the winds (95km/h) are presented also.

Texto completo da fonteThe aim of this work is to contribute to the understanding the processes that define the propagation of Amazon Tropical Squall Lines (ASL). 9 years of satellite images were analyzed defining ASL cases and their relationship with environment characteristics. The low level jet (LLJ) in ASL propagation has emerged as an important feature and possible differences between the systems that propagated and systems that did not propagate were analyzed. The observational analyzes suggested a series of numerical simulations with BRAMS model to explore the sensitivity of propagating ASL with respect to the kinematic characteristics of environment. Main results show that the larger number of ASL cases was of non propagating coastal lines. From the total, only 20% of ASL propagated more than 400 km (SL2). The wind profile of ASL formation and development environment had a LLJ, an upper level jet and to small values of speed and directional shear. The LLJ was from east with intensity of about 9 ms-1 and it was occurred around 800 hPa. It was more intense and deeper for SL2 than CSL. The 2005 and 2006 years had an considerable increase of ASL cases, specially for propagated lines. The 2005 year was atypical, because had an increase of sea surface temperature of Tropical Atlantic Ocean, allowing to speculate that this kind of increase, in certain areas of the Ocean, can lead to the deepening of LLJ through of easterly wave intensification, and thus favoring the formation of more ASL in the North coast of Brazil. The LLJ has a important role in the development processes of cumulus towers that compose the ASL and not only it were responsible for organization of the system, but it directly influence the internal processes of clouds, like inflow into the cloud.
