Two New Species of <i>Prosorhynchinaei> (Trematoda : Gasterostomata) from the Fiji Islands

The following trematodes are part of a collection made by the author at Suva, Fiji in 1951. 1. Prosorhynchus squamatus Odhner, 1905 is believed to be distinct from P. crucibulus and most other species in the genus on the basis of its oval-shaped rhynchus. It thus remains, as originally, the type species of the genus. 2. Prosorhynchus thapari n. sp. is described from Plectropoma maculatum (Bloch) from Suva, Fiji. The "P. facilis (Ozaki, 1924)" of Nagaty (1937) is considered to be a synonym. 3. Neidhartia polydactyli n. sp. is described from Polydactylus plebius (Bonnaterre) from Suva, Fiji.

Pela construção de um estado de crítica: a reflexão crítica como campo dialógico

O texto aqui apresentado foi originalmente elaborado para o debate sobre a crítica de arte no I Congresso de Jornalismo realizado em São Paulo, pela Revista Cult, em Maio de 2009. Tendo como campo de trabalho a prática artística e a docência e envolvida no processo de formação de artistas desde 1982, meu objetivo foi argumentar a favor de um entendimento da crítica como dispositivo da arte e, portanto, atributo não só de críticos, mas também de artistas. Defendo a idéia da manutenção de um ‘estado de crítica' para o contexto brasileiro a partir de uma relação dialógica e internacionalizada, envolvendo também a fala crítica de artistas. Para isso reporto às práticas adotadas no século XX pelos artistas que colaboraram para inserir a obra de arte no campo programático da auto-crítica e da crítica ao sistema, evidenciando assim a posição destes como agente ativos no sistema

Crisis y superación en el ámbito de la Geografía crítica: construyendo la metageografía.

El punto de inicio del razonamiento desarrollado para la construcción de lo que se denomina metageografía, parte con el reconocimiento de un estado de crisis en la Geografía, y en segundo lugar, de su rol como posibilidad, a pesar de ser una ciencia fragmentada, de comprender el mundo moderno, pues su conocimiento puede constituirse en un movimiento hacia la totalidad. En un sentido más amplio, se reflexiona sobre el lugar de la Geografía en la explicación de la realidad en constante cambio. ¿Es posible pensar que, a pesar de sus avances, la Geografía se encuentra en un estado de crisis? Nos enfrentamos con la obligación de revelar sus indicios y, por consiguiente, la necesidad de construir un camino hacia adelante en la necesidad de comprender la realidad desde o por la Geografía. La metageografía es una propuesta teórico-metodológica para la superación de la situación de crisis en que la disciplina se encuentra, a partir de la práctica socioespacial como modo explicativo.

Luis Arana e i veterani di Euzkeldun Batzokija: la corrente ortodossa del nazionalismo basco

La tesi di Marco Perez intitolata “Luis Arana e i veterani di Euzkeldun Batzokija: la corrente ortodossa del nazionalismo basco”, può essere considerata come la biografia politica di uno dei personaggi più importanti del nazionalismo basco. Il lavoro di ricerca si centra fondamentalmente sull'ispiratore del nazionalismo euskaldun (e cofondatore del Partido Nacionalista Vasco) e della corrente che ne accompagnò e sostenne l'azione politica. Euzkeldun Batzokija fu il nome dato al primo circolo del PNV, fondato da Luis e Sabino Arana nel 1894. Successivamente, gli statuti del circolo e i suoi membri veterani furono presi come modello del nazionalismo primordiale (che si pretendeva definire sull'esempio dell'Ordine gesuita). Sul piano organizzativo la tesi si divide in sette capitoli che ricostruiscono il percorso politico di Luis Arana, dai primi documenti del 1879 fino alle ultime lettere inviate negli anni quaranta. Si tratta di un lungo periodo, che comprende momenti diversi della storia spagnola (dalle guerre carliste alla Guerra Civile spagnola) e del movimento aranista. In questo senso, sulla base di una generale e comparata riflessione sul nazionalismo, si analizza il movimento basco nei suoi rapporti con la modernità. Una realazione costruita attraverso concetti “diacronicamente” legati a un passato mitico e leggendario e comunque subalterna ai rapporti di forza tra le correnti del PNV. La corrente ortodossa fece sempre riferimento al nazionalismo “originario” (definito dai fratelli Arana nei primi anni del movimento) che fu un'espressione regionale del nazionalcattolicesimo spagnolo. Fu proprio Luis Arana a ricordare la finalità religiosa ed etnica del nazionalismo basco, respingendo qualsiasi aggiornamento teorico e organizzativo del PNV, intesi come una grave violazione dell'ortodossia aranista.

La costruzione delle relazioni politiche ed economiche tra l'Italia e la Germania occidentale dopo la seconda guerra mondiale (1945-1951)

L’autore ricostruisce ed esamina la storia dei rapporti italo-tedeschi negli anni immediatamente precedenti la riapertura ufficiale delle relazioni diplomatiche tra Italia e Repubblica federale tedesca. Un riavvicinamento economico e politico progressivo, ma che suscitò forti contrasti tra i principali attori della diplomazia italiana. Il saggio si basa su una documentazione conservata presso l’Archivio storico del ministero degli Esteri, l’Archivio centrale dello Stato, l’Archivio storico della Banca d’Italia e l’Archivio Politico del ministero degli Esteri della Repubblica federale. L’autore sostiene che le relazioni economiche italo-tedesche assunsero un ruolo centrale nel processo di elaborazione della politica estera italiana sulla questione tedesca nel corso di questi anni. Prima dell’istituzione della Repubblica federale tedesca, l’Italia divenne un partner economico fondamentale per la Germania occidentale. Tra il 1945 e il 1949 l'Italia fu il primo paese europeo favorevole alla rinascita di un nuovo stato tedesco non sottoposto alla diretta influenza dell’Unione Sovietica. Il presidente del Consiglio De Gasperi e il ministro degli Esteri Sforza per sostenere la nuova Germania attuarono una precisa azione diplomatica di riavvicinamento politico, promuovendo diversi scambi di visite e di incontri con i rappresentanti tedeschi.

[Impact of tobacco use on the periodontium--an update (I)--Part 1: Epidemiologic und pathogenetic aspects of tobacco-related periodontal diseases]

This literature review represents the second in a series of articles from the Swiss task force "Smoking--Intervention in the private dental office" on the topic "tobacco use and dental medicine". In this article, the epidemiological background as well as some pathogenetic processes are described and discussed critically for tobacco-related periodontal diseases. Earlier publications confirmed tobacco consumption as a risk factor for periodontal diseases. Over the last few years, oral health research has significantly contributed to the understanding of the mechanisms leading to the deterioration of the hard and soft tissues supporting the teeth. With the recording of the number of cigarettes smoked per day and the amount of years tobacco was used, a dose response relationship was established. Various, potentially significant pathogenic effects of tobacco-related substances may exist on the periodontal tissues, the immune response system or the composition of the oral flora. Moreover, there is reference that tobacco consumption may change the genetically determined susceptibility for periodontal diseases.

[Effects of tobacco use on general health: relevant information for dentistry (I)--part 1: pulmonary diseases and other malignancies]

This fifth part of a series of publications from the Swiss task force named "Smoking--Intervention in the private dental office" on the topic "tobacco use and dental medicine" focuses on the effects of tobacco use on general health. A significant increase of tobacco use associated morbidity and mortality for many cardiovascular and pulmonary diseases has been well documented in the literature. In this review, the epidemiologic background as well as the pathophysiological fundamentals for tobacco-mediated pulmonary diseases is presented, focusing especially on chronic obstructive pulmonary disease (COPD) and lung cancer. In addition, a causal relationship between nicotine abuse and an increased carcinoma incidence for other malignancies but lung cancer will be discussed. Regarding the evidence in the present literature, it is undisputable that smoking is the most preventable cause for COPD and lung cancer.

Switch from type II to I Fas/CD95 death signaling on in vitro culturing of primary hepatocytes

Fas/CD95-induced apoptosis of hepatocytes in vivo proceeds through the so-called type II pathway, requiring the proapoptotic BH3-only Bcl-2 family member Bid for mitochondrial death signaling. Consequently, Bid-deficient mice are protected from anti-Fas antibody injection induced fatal hepatitis. We report the unexpected finding that freshly isolated mouse hepatocytes, cultured on collagen or Matrigel, become independent of Bid for Fas-induced apoptosis, thereby switching death signaling from type II to type I. In such in vitro cultures, Fas ligand (FasL) activates caspase-3 without Bid cleavage, Bax/Bak activation or cytochrome c release, and neither Bid ablation nor Bcl-2 overexpression is protective. The type II to type I switch depends on extracellular matrix adhesion, as primary hepatocytes in suspension die in a Bid-dependent manner. Moreover, the switch is specific for FasL-induced apoptosis as collagen-plated Bid-deficient hepatocytes are protected from tumor necrosis factor alpha/actinomycin D (TNFalpha/ActD)-induced apoptosis. Conclusion: Our data suggest a selective crosstalk between extracellular matrix and Fas-mediated signaling that favors mitochondria-independent type I apoptosis induction.

XIAP discriminates between type I and type II FAS-induced apoptosis

FAS (also called APO-1 and CD95) and its physiological ligand, FASL, regulate apoptosis of unwanted or dangerous cells, functioning as a guardian against autoimmunity and cancer development. Distinct cell types differ in the mechanisms by which the 'death receptor' FAS triggers their apoptosis. In type I cells, such as lymphocytes, activation of 'effector caspases' by FAS-induced activation of caspase-8 suffices for cell killing, whereas in type II cells, including hepatocytes and pancreatic beta-cells, caspase cascade amplification through caspase-8-mediated activation of the pro-apoptotic BCL-2 family member BID (BH3 interacting domain death agonist) is essential. Here we show that loss of XIAP (X-chromosome linked inhibitor of apoptosis protein) function by gene targeting or treatment with a second mitochondria-derived activator of caspases (SMAC, also called DIABLO; direct IAP-binding protein with low pI) mimetic drug in mice rendered hepatocytes and beta-cells independent of BID for FAS-induced apoptosis. These results show that XIAP is the critical discriminator between type I and type II apoptosis signalling and suggest that IAP inhibitors should be used with caution in cancer patients with underlying liver conditions.

Somatostatin-based radiotherapy with [90Y-DOTA]-TOC in neuroendocrine tumors: long-term outcome of a phase I dose escalation study

BACKGROUND We describe the long-term outcome after clinical introduction and dose escalation of somatostatin receptor targeted therapy with [90Y-DOTA]-TOC in patients with metastasized neuroendocrine tumors. METHODS In a clinical phase I dose escalation study we treated patients with increasing [90Y-DOTA]-TOC activities. Multivariable Cox regression and competing risk regression were used to compare efficacy and toxicities of the different dosage protocols. RESULTS Overall, 359 patients were recruited; 60 patients were enrolled for low dose (median: 2.4 GBq/cycle, range 0.9-7.8 GBq/cycle), 77 patients were enrolled for intermediate dose (median: 3.3 GBq/cycle, range: 2.0-7.4 GBq/cycle) and 222 patients were enrolled for high dose (median: 6.7 GBq/cycle, range: 3.7-8.1 GBq/cycle) [90Y-DOTA]-TOC treatment. The incidences of hematotoxicities grade 1-4 were 65.0%, 64.9% and 74.8%; the incidences of grade 4/5 kidney toxicities were 8.4%, 6.5% and 14.0%, and the median survival was 39 (range: 1-158) months, 34 (range: 1-118) months and 29 (range: 1-113) months. The high dose protocol was associated with an increased risk of kidney toxicity (Hazard Ratio: 3.12 (1.13-8.59) vs. intermediate dose, p = 0.03) and a shorter overall survival (Hazard Ratio: 2.50 (1.08-5.79) vs. low dose, p = 0.03). CONCLUSIONS Increasing [90Y-DOTA]-TOC activities may be associated with increasing hematological toxicities. The dose related hematotoxicity profile of [90Y-DOTA]-TOC could facilitate tailoring [90Y-DOTA]-TOC in patients with preexisting hematotoxicities. The results of the long-term outcome suggest that fractionated [90Y-DOTA]-TOC treatment might allow to reduce renal toxicity and to improve overall survival. (ClinicalTrials.gov number NCT00978211).
