Résultats écophysiologiques de la vigne au Portugal. Aspects hydriques

Dans la vigne au Portugal les effets provoqués par le stress hydrique et les températures élevées se superposent fréquemment sur les effets dûs aux systèmes de conduite (Chaves & Pereira, 1987; Chaves & Rodrigues, 1987; Clímaco et al., 1991; Lopes & Castro, 1992). Bien que la vigne ait une capacité pour survivre dans des conditions de sécheresse (Champagnol, 1984) les échanges gazeux, la croissance et la maturation des baies peuvent être affectés. Le niveau auquel ces processus sont affectés dépend, parmis d'autres facteurs, de l'intensité du stress (Williams & Matthews, 1990), de l'époque où il se révèle (Smart & Coombe, 1983) et aussi du cépage (Düring & Klingenmeyr, 1987; Regina & Carbonneau, 1992). Dans ce travail nous avons observé l ́effet de la disponibilité hydrique du sol sur les échanges gazeux et l'état hydrique des plantes en deux cépages - Fernão Pires (B) et Periquita (N) - cultivés en trois terroirs situés dans la région agricole "Ribatejo et Oeste"info:eu-repo/semantics/publishedVersio

The A54T polymorphism in the FABP2 gene and its relationship with obesity

Introduction: Obesity is a complex, multifactorial, and mostly preventable disease affecting, along with overweight, more than a third of today’s world population. Variations in the nucleotide sequence of both metabolic and appetite control genes have been counted among these non-modifiable factors and are associated with BMI, lipidic profile, and abdominal circumference alterations. Methods: An analytical, non-experimental, and transversal research was done with the purpose to assess the presence of A54T polymorphism in the FABP gene in a sub-sample from the Maracaibo City Metabolic Syndrome Prevalence Study. Results: 154 individuals eight subjects were carriers of the A54Tpolymorphism, namely, a genotypic frequency of 5.19 %, with a sex distribution of 50 % for women (n=4) and 50 % (n=4) for men. In respect of alleles similarity degree, 75 % (n=6) were homozygous, and 25 % (n=2) were heterozygous. Obesity diagnosis throughout BMI was only present in 12.50 % (n=1) of the A54T carriers. Conversely, 25 % (n=2) of the carriers were overweighed; 50 % (n=4) were presented as normal-weight people; and only 12.50 % (n=1), in one underweighted person. Conclusion: As in many other studies, we do not find an association between Ala54Thr polymorphism and obesity. This result reinforces the fact of the multifactorial character of these diseases and a carrier state of this polymorphism is not necessarily to experience a higher obesity risk, at least, in our environment.La obesidad es una enfermedad compleja, multifactorial y en su mayor parte prevenible que afecta, a más de un tercio de la población mundial actual. Las variaciones en la secuencia de nucleótidos de los genes de control del metabolismo y del apetito se consideran hasta ahora como factores no modificables y se asocian con alteraciones del IMC, del perfil lipídico y de la circunferencia abdominal. Métodos: Se realizó una investigación analítica, no experimental y transversal con el propósito de evaluar la presencia del polimorfismo A54T en el gen FABP en una submuestra del Estudio de Prevalencia del Síndrome Metabólico de la Ciudad de Maracaibo. Resultados: De los 154 individuos de la submuestra ocho sujetos fueron portadores del polimorfismo A54T, es decir, una frecuencia genotípica de 5,19 %, con una distribución por sexo de 50 % para las mujeres (n=4) y 50 % (n=4) para los hombres. Con respecto al grado de similitud de los alelos, el 75 % (n=6) eran homocigotos y el 25 % (n=2) heterocigotos. El diagnóstico de obesidad a lo largo del IMC sólo estuvo presente en el 12,50 % (n=1) de los portadores de A54T. Por el contrario, el 25 % (n=2) de los portadores tenían sobrepeso; el 50 % (n=4) se presentaron como personas de peso normal; y sólo el 12,50 % (n=1) en la categoría de peso insuficiente. Conclusión: No se encontró una asociación entre el polimorfismo de Ala54Thr y la obesidad. Este resultado refuerza el carácter multifactorial de estas enfermedades y que un estado portador de este polimorfismo no es causa necesaria para padecer obesidad, al menos, en nuestro medio

Isolation of microsatellite loci in the Amazon sailfin catfish Pterygoplichlhys pardalis (Castelneau, 1855) (Teleostei: Loricariidae).

Pterygoplichlhys pardalis is an important freshwater ornamental fish in the Amazon Basin. Studies involving populations of P. pardalis are of great importance for the conservation and management of this species. We developed nine microsatellite loci and applied them to investigate the genetic variation of 20 wild individuals from floodplain lakes of the Solimões river. The number of alleles per locus ranged from 2 to 12, with an average of 6.6. The observed and expected heterozygosity values ranged from 0.400 to 0.923 (average 0.706) and from 0.358 to 0.895 (average 0.692), respectively. The value of f ranged from -0.532 to 0.467 (average 0.032). One locus (Pp07) significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction (P: (5 %)\0.006). No significant linkage disequilibrium was detected. These microsatellite loci will contribute towards studies of genetic diversity and conservation of P. pardalis

Climatic groups in Ibero-Ameríca viticulture compared to worldwide wine producer regions.

Thewine production is an important activity in many Ibero-American countries. The wine producer regions of these countriesconfigure a large use of different c1imate types and viticultural climates. ln a vitivinicultural zoning project of CYTED (Ibero-American Program for Science, Technology and Development), a viticultural c1imatic characterization was done in this macro viticultural region. The project have assembled a climatic database that characterizes the viticultural regions, inc1uding relevant variables for viticulture: air emperature (mean, maximum, and minimum), precipitation, relative humidity, solar radiation, number of sunshine hours, wind speed, and evapotranspiration. Using indicesof the Geoviticulture MCC System (HI, CI and DI), more than 70 viticultura I regions in different countries (Argentina,Bolivia, Brazil, Chile, Cuba, Spain, Mexico, Peru, Portugal and Uruguay) were characterized according to itsviticultural c1imatic. The results, which will be integrated to the worldwide database of the MCC System, showed thatthe Ibero-American viticulture is placed in a wide range of c1imatic groups of the wine producing regions around lheworld. This article presents the c1imatic groups found in Ibero-America, identifying also some new climatic groups notyet found in other regions of the world. This work also identifies some c1imatic groups not found in Ibero-America viticulture.The research has also highlighted viticultural areas characterized by c1imates with "intra-annual c1imatic variability",with the potential to produce more than one growing cyc1e per year. The results allow to conc1ude that the wide variability and climatic diversity present in Ibero-America may be one of the reasons to explain the diversity in terms ofwine types, sensorial characteristics, typicity and uniqueness ofwines produced on this macro-region

Para o estudo da evolução do ensino e da formação em administração educacional em Portugal

Estudos sobre a evolução do ensino de disciplinas, na formação de professores em Portugal, são recentes. O controle burocrático centralizado reteve as dimensões do controle político-administrativo. De certo modo, protegeu a esfera educativa das influências modernizantes, do capitalismo industrial e das lógicas mercantis e gerencialistas. Defendeu a educação do domínio político, da intervenção de movimentos sociais, das propagandas de ideais democráticos e da cidadania. A utilização da designação "Administração educacional" ilustra as dificuldades sentidas, ao longo dos últimos anos, em termos da construção acadêmica de uma área, seja pela falta de tradição, seja pelos antecedentes históricos.In Portugal, studies about the evolution of disciplines teaching in the teachers formation are recent. The centralized bureaucratic control has held back the dimensions of politic administrative control. In a certain way, it has protected the education against the new-fashioned influences, manufacturing capitalism, and mercantile and managerial logics. This centralized bureaucratic control has also profected the education against the politic dominion, the intervention of social movements, the advertising of democratic ideals, and against the citizenship. The use of the term "Educational administration" shows the difficulties met by the searchers along the latest years, since there is no tradiction nor historic antecedence
