Nous factors inflamatoris de la diabetis tipus 2: SP-D, SP-A, a-Defensives i visfatina

La DM 2 és una malaltia multifactorial i multigènica. Aquest fet condueix a l'estudi de molts gens i proteïnes susceptibles d'estar implicades amb la DM 2. Algunes d'aquestes proteïnes i gens estan associats a un estat lleu d'inflamació crònica, la qual pot desencadenar la síndrome metabòlica (SRI) i DM 2. Moltes d'aquestes proteïnes poden usar-se com a possibles marcadors de malaltia cardiovascular, resistència a la insulina i futura DM 2. Aquest treball presenta quatre proteïnes i la seva relació amb la SRI i la DM 2. L'SP-D i l'SP-A s'estudien per la relació que hi ha entre la disminució de la funció pulmonar i la resistència a la insulina i pel fet de ser moduladores de la inflamació. Les α-defensines s'estudien perquè també són moduladores de la inflamació i per una possible relació amb l'arteriosclerosi i el colesterol LDL. La visfatina s'estudia per la possible associació amb la insulinosecreció.

“Pai contra mãe” De Machado de Assis: um grito contra a escravatura

Partindo da análise do conto «Pai contra mãe», do escritor brasileiro Machado de Assis, é traçada a história da escravatura no Brasil, com referência à obra de Stefan Zweig e de Gilberto Freire. A teoria do «bom colonizador», defendida por Gilberto Freire, contrasta dramaticamente com o testemunho literário constituído pelo conto em análise. A escravatura aparece na sua verdadeira dimensão de exclusão e sofrimento, desenhada magistralmente pelo génio de Machado de Assis.

Sistemas de mediação, elementos construtivos e espaciais : o exemplo da arquitetura das casas monásticas femininas de clausura

A Arquitetura monástica feminina, pode caracterizar-se como um sistema, cuja função primordial é mediar a relação entre o interior e o exterior da cerca do Mosteiro. Do ponto de vista da solução arquitetónica e na sua abordagem construtiva, mais interessante que refletir sobre os sistemas construtivos que asseguraram a estabilidade destas estruturas ou sobre a natureza dos materiais que lhes dão forma, será compreender que existem outros elementos de natureza construtiva, assim como espacial que em si mesmo definem o conceito de casa feminina de clausura, por garantirem a efetiva separação entre os dois mundos, o de dentro e o de fora.

Cuerpo, dolor y memoria. Usos sociales y políticos del cuerpo en las performances de Daniel Brittany Chávez, Regina José Galindo, Daniel Coka y María José Machado

En esta investigación, la autora propone un análisis de la performance latinoamericana desde la concepción del cuerpo como político, lo que implica analizar el cuerpo dentro de su existencia histórica antes que biológica, cobrando gran importancia el contexto y las experiencias vividas como detonantes de estas prácticas artísticas, que muchas veces conllevan acciones de dolor físico, las cuales, dentro de la concepción política del cuerpo, se convierten en actos de memoria. Estos planteamientos de los usos sociales y políticos del cuerpo son analizados en las performances de Daniel Brittany Chávez, Regina José Galindo, María José Machado y Daniel Coka.

Antifungal activity of Bacillus subtilis filtrate to control Fusarium oxysporum f.sp. lentis, the causal organism of lentil vascular wilt

In dual cultures, the supernatant filtrate of the biological control agent Bacillus subtilis was evaluated against (Fusarium oxysporum f.sp. lentis) the causal organism of lentil vascular wilt. The antagonistic activity was evaluated as percent reduction of fungal growth (certainly due, in part, to the antifungal metabolites produced by the antagonistic bacterium). The in-vitro experiments showed that B. subtilis filtrate, whether solid or liquid media, had a strong inhibiting activity on the spore germination and mycelial growth of F. oxysporum f. sp. lentis. In a glasshouse experiment, soil was drenched with B. subtilis filtrate at 30 ml/kg (vol/wt) around seedlings of a susceptible lentil line (ILL 4605). In this treatment there was only 31% mortality compared with 100% kill of plants in the control treatment (P≤0.05).

Formulation and delivery of the bacterial antagonist Bacillus subtilis for management of lentil vascular wilt caused by Fusarium oxysporum f. sp lentis

Different formulations of Bacillus subtilis were prepared using standard laboratory protocols. Bacillus subtilis survived in glucose and talc powders at 8.6 and 7.8 log(10) CFU/g, respectively, for 1 year of storage at room temperature compared with 3.5 log(10) CFU/g on a peat formulation. Glasshouse experiments using soil and seed treatments were conducted to test the efficacy of B. subtilis for protecting lentil against the wilt disease caused by Fusariumoxysporum f. sp. lentis. Seed treatments with formulations of B. subtilis on glucose, talc and peat significantly enhanced its biocontrol activity against Fusarium compared with a treatment in which spores were applied directly to seed. The formulations decreased disease severity by reducing colonization of plants by the pathogen, promoting their growth and increased the dry weight of lentil plants. Of these treatments the glucose and talc-based powder formulations were more effective than the peat formulation and the spore application without a carrier. It was shown that the B. subtilis spores applied with glucose were viable for longer than those applied with other carriers. Seed treatment with these formulated spores is an effective delivery system that can provide a conducive environment for B. subtilis to suppress vascular wilt disease on lentil and has the potential for utilization in commercial field application.

Antagonistic potential of bacterial isolates associated with entomopathogenic nematodes against tomato wilt caused by Fusarium oxysporum f.sp., Lycopersici under greenhouse conditions

Three concentrations of Xenorhabdus nematophila and Xenorhabdus spp., (4x10(5,) 4x10(6,) 4x10(7) cells/ml) were evaluated in the laboratory and in pot experiments to test their antagonistic effects on Fusarium oxysporum f.sp., lycopersici. All concentrations effectively inhibited its growth on agar plates. In soil under greenhouse conditions treatments with each bacterium at 4x10(7) cells/ml reduced the disease incidence of tomato by up to 40.38 and 47.54% respectively and there were significant increases of plant biomass by 198 and 211% respectively. The rhizosphere population of Fusarium oxysporum f.sp., lycopersici was reduced by 97%. The Xenorhabdus spp., was comparatively more effective than X. nematophila.

Predation of Bradysia sp (Diptera: Sciaridae), Liriomyza trifolii (Diptera: Agromyzidae) and Bemisia tabaci (Hemiptera: Aleyrodidae) by Coenosia attenuata (Diptera: Muscidae) in greenhouse crops

We studied the predation behaviour of the "hunter fly" (Coenosia attenuata Stein) in the laboratory and greenhouse. In the laboratory, which was conducted at 25 degrees C at 60-80% RH, with a 16L : 8D photoperiod, we examined the functional response of this species to three different pests, namely the sciarid fly (Bradysia sp.), the tobacco whitefly (Bemisia tabaci) and the leaf miner Liriomyza trifolii. In the greenhouse, we studied the population dynamics of the predator and its prey on pepper and water melon crops grown in southern Spain. Adult hunter flies were found to exhibit a type I functional response to adult sciarid flies and whiteflies, but a type II response to adult leaf miners. The type II response was a result of the greater difficulty in capturing and handling leaf miners compared to the other two species. The dynamics of the predator-prey interaction in the greenhouse revealed that the predator specializes mainly on adult sciarids and that the presence of the other prey can be supplemental, but is never essential for survival of the predator; this, however, is crop-dependent. The results oil the dynamics of the predator-prey systems were obtained through a known population dynamics model with modifications.
