Índice de vegetação espectral em áreas cafeeiras e sua relação com a precipitação em Três Pontas, Minas Gerais.

Atualmente, eventos e variações climáticas estão sendo intensamente discutidos e, por este motivo, é de fundamental importância a realização de estudos microrregionais, que visam o monitoramento do desenvolvimento de lavouras cafeeiras e a compreensão da dinâmica da produtividade associada às variações meteorológicas. Convencionalmente, o monitoramento agrometeorológico da cafeicultura tem sido realizado em campo, porém, estudos mais recentes utilizam imagens de satélite que permitem avaliar grandes áreas a custos menores e com maior frequência de imageamento. Nesse sentido, o sensor Moderate Resolution Imaging Spectroradiometer (MODIS) do satélite TERRA oferece, gratuitamente, imagens com alta resolução temporal e produtos voltados especialmente para vegetação, como o MOD13Q1, que contém o índice de vegetação Normalized Difference Vegetation Index (NDVI). Assad, Setzer e Moreira (1988) estudaram a correlação entre dados de imagens de satélite e meteorológicos e observaram que a pluviometria é um dos fatores mais limitantes do desenvolvimento da vegetação. O objetivo deste trabalho foi avaliar a variação temporal dos valores de NDVI, fornecidos pelo produto MOD13Q1 do sensor MODIS/TERRA, do ano de 2008, e associá-los à pluviosidade

Immunoexpression Of α2-integrin And Hsp47 In Hereditary Gingival Fibromatosis And Gingival Fibromatosis-associated Dental Abnormalities

Objective: The purpose of the present study was to investigate the expression of the α2-integrin subunit and heat shock protein 47 (Hsp47) in two families with isolated gingival fibromatosis (GF) form and one family with GF associated with dental abnormalities and normal gingiva (NG). Study Design: Immunohistochemistry was performed with antibodies against α2-integrin and Hsp47 in specimens from two unrelated families with hereditary gingival fibromatosis (Families 1 and 2) and from one family with a gingival fibromatosis-associated dental abnormality (Family 3); NG samples were used for comparison. The results were analysed statistically. Results: Immunoreactivity for α2-integrin and Hsp47 was observed in the nucleus of epithelial cells of both the basal and suprabasal layer and a more discreet signal was noted in connective tissue in all study samples. Hsp47 showed higher immunoreactivity in Family 2 compared with the other families (p≤0.05). Despite the markup α2-integrin was higher in Family 3 there was no statistically significant difference between the families studied (p≥0.05). Conclusions: Our results confirmed the heterogeneity of GF, such that similar patterns of expression of the condition may show differences in the expression of proteins such as Hsp47. Although no difference in α2-integrin expression was observed between GF and NG groups, future studies are necessary to determine the exact role of this protein in the various forms of GF and whether it contributes to GF pathogenesis. © Medicina Oral S.
