First report of Ascarophis Van Beneden, 1871: A. Brasiliensis n.sp. (Nematoda, Ascarophidinae) and Procamallanus (Spirocamallanus) Pereira/Annereaux, 1946 (Nematoda, Procamallaninae) in South America

Ascarophis brasiliensis recovered from the stomach of Trachinotus carolinus (L. 1766), is proposed as a new species and Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 is redescribed from a new host: Paralonchurus brasiliensis (Steind., 1875). A. brasiliensis is more closely related to A. crassicolis Dollfus & Campana-Rouget, 1956, from which it differs mainly by the absence of cervical cuticular expansion and size of the eggs. The new species is also compared to A. cooperi johnston & Mawson, 1945 and A. girellae (Yamaguti, 1935) Campana-rouget, 1955. The validity of the proposed species is discussed.

Otodistomum cestoides (Van Beneden, 1871) from two species of skates taken in chilean waters

Otodistomum cestoides (van Beneden, 1871) (Azygiidae: Digenea) is reported for the first time from Psammobatis scobina and Raja flavirostris. The skates were caught off the coast of San Antonio, Chile.

Geografia associativa e imperialismo svizzero. Il caso di Ginevra (1858-1914)

ASSOCIATIVE GEOGRAPHY AND SWISS IMPERIALISM. THE EXAMPLE OF GENEVA (1858-1914) − This article is about geographical society of Geneva and its involvement in the 19th century colonial imperialism. Through this society, Swiss bourgeoisie takes part in the exploration and colonization of the world. Is this participation a sign of Swiss imperialism? This issue will be at the heart of this study.

Inversion Analytics: Análisis sobre rentabilidad de inversiones mediante VAN y TIR

Inversion Analytics es una herramienta para facilitar el análisis en inversiones que se planteen en pequeñas, medianas y grandes empresas, en el que se plasmará toda la información necesaria para determinar los valores que entran en juego en la inversión. La aplicación realiza esta función mediante el cálculo de VAN (Valor Actual Neto) y TIR (Tasa Interna de Rentabilidad) de una inversión determinada, a partir de la información introducida por el usuario y teniendo en cuenta los distintos métodos de amortización de la inversión inicial, así como los distintos enfoques o supuestos en el que clasificaremos el horizonte temporal de la misma.

Comportamento reprodutivo de Synthesiomyia nudiseta van der Wulp (Diptera: Muscidae) sob condições de laboratório

Observations were carried out on the reproductive behavior of Synthesiomyia nudiseta females. The results of the biological parameters were: pre-oviposition period (15.5 ± 4.7 days), oviposition period (25.4 ± 14.7 days), number of eggs per oviposition (95.9 ± 18.4) rate of ovipositant females (97.5%), number of ovipositions (5.31 ± 3.2), number of eggs per females (509.7 ± 324.9), rate of hatching (68.0 ± 19.0), female longevity (53.2 ± 14.7 days), reproductive potential (67.4%) and reproductive investiment (4.1).

Dieu, vingt-six portraits bibliques

Vingt-six portraits par vingt-six exégètes. Tel est le défi proposé et assumé pour un parcours surprenant de lectures et d'interprétations multiples d'un Dieu unique et en même temps complexe. Quelle cohérence entre le Dieu fracassant de l'Exode et le Dieu crucifié de l'apôtre Paul ? Quelle continuité entre le Dieu de Gédéon et celui de Jésus : " Mon Dieu, mon Dieu, pourquoi m'as-tu abandonné ? " (Mc 15,34) ? Le Dieu de l'entrée en Canaan ressemble-t-il vraiment à l'Agneau immolé de l'Apocalypse ? Mais déjà, au sein de la Bible hébraïque, les trompettes de Jéricho côtoient le Serviteur souffrant d'Isaïe. Comment comprendre aujourd'hui cette diversité de la présence de Dieu dans la Bible, si ce n'est par la diversité des regards d'exégètes dont la lecture croisée des textes bibliques nous invite à renouveler notre compréhension de Dieu ?

Ex vivo detectable activation of Melan-A-specific T cells correlating with inflammatory skin reactions in melanoma patients vaccinated with peptides in IFA.

The purpose of this study was to test melanoma vaccines consisting of peptides and immunological adjuvants for optimal immunogenicity and to evaluate laboratory immune monitoring for in vivo relevance. Forty-nine HLA-A2 positive patients with Melan-A positive melanoma were repeatedly vaccinated with Melan-A peptide, with or without immune adjuvant AS02B (QS21 and MPL) or IFA. Peptide-specific CD8 T cells in PBLs were analyzed ex vivo using fluorescent HLA-A2/Melan-A multimers and IFN-gamma ELISPOT assays. The vaccines were well tolerated. In vivo expansion of Melan-A-specific CD8 T cells was observed in 13 patients (1/12 after vaccination with peptide in AS02B and 12/17 after vaccination with peptide in IFA). The T cells produced IFN-gamma and downregulated CD45RA and CD28. T-cell responses correlated with inflammatory skin reactions at vaccine injection sites (P < 0.001) and with DTH reaction to Melan-A peptide (P < 0.01). Twenty-six of 32 evaluable patients showed progressive disease, whereas 4 patients had stable disease. The two patients with the strongest Melan-A-specific T-cell responses experienced regression of metastases in skin, lymph nodes, and lung. We conclude that repeated vaccination with Melan-A peptide in IFA frequently leads to sustained responses of specific CD8 T cells that are detectable ex vivo and correlate with inflammatory skin reactions.

Laboratory evaluation of Mesocyclops annulatus (Wierzejski, 1892) (Copepoda: Cyclopidea) as a predator of container-breeding mosquitoes in Argentina

In laboratory bioassays we tested the predatory capacity of the copepod Mesocyclops annulatus on Aedes aegypti and Culex pipiens larvae. A single adult female of M. annulatus caused 51.6% and 52.3% mortality of 50 first instar larvae of Ae. aegypti and Cx. pipiens respectively, in a 72 h test period. When alternative food was added to the containers, mortality rates declined to 16% and 10.3% for Ae. aegypti and Cx. pipiens respectively. When 50 first instar larvae of each of the two mosquito species tested were placed together with a single adult female of M. annulatus, mortality rates were 75.5% for Ae. aegypti larvae and 23.5% for Cx. pipiens larvae in a three day test period. Different density of adult females of M. annulatus ranged from 5 to 25 females produced mortality rates of Ae. aegypti first instar larvae from 50% to 100% respectively. When a single adult female of M. annulatus was exposed to an increasing number of first-instar Ae. aegypti larvae ranging from 10 to 100, 100% mortality was recorded from 1 to 25 larvae, then mortality declined to 30% with 100 larvae. The average larvae killed per 24 h period by a single copepod were 29.

La Inspiració de Van Gogh

La Inspiració de Van Gogh ofereix una reflexió entre les similituds i coincidències de dues societats (la societat de finals del sXIX, i la societat actual) separades pel temps, però unides per la necessitat de trobar una sortida a tanta incomprensió artística i social.
