Corn (Zea mays L.) plants were assayed for nitrogenase activity (C(2)H(2) reduction) during early ear development. Hybrid corn and inbred lines were grown separately at two experimental fields in New Jersey. Acetylene-dependent ethylene production was observed a few hours after harvest, from the field, on intact plants, root-soil cores, lower stem segments, and excised roots, all assayed under air and not preincubated previously. Incubation of excised roots at 1% O(2) resulted in lower rates of C( ...

Dentre um total de 16.423 internações, houve 694 gestantes com o diagnóstico de cardiopatia (4,2%). No mesmo período, ocorreram 51 óbitos maternos, correspondendo a um coeficiente de mortalidade materna de 428,2/100.000 nascidos vivos. Houve 12 óbitos maternos por cardiopatia. A análise estatística permitiu a identificação de alguns fatores associados a maior risco de morte nas ...

ABSTRACT Xylella fastidiosa was isolated from sweet orange plants ( Citrus sinensis ) grown in two orchards in the northwest region of the Brazilian state of São Paulo. One orchard was part of a germ plasm field plot used for studies of citrus variegated chlorosis resistance, while the other was an orchard of C. sinensis cv. Pêra clones. These two collections of strains were genotypically characterized by using random amplified polymorphic DNA (RAPD) and variable number of tandem repeat (VNTR) markers. ...

ABSTRACT: : Technology for the production of edible cassava chips was studied, using pretreatments such as cooking and partial drying to improve chip crispness. Different cassava varieties and types of cooking, such as boiling water and steam, were also investigated. The effects of such treatments were evaluated on chip friability criteria by using the Texture Analyzer TA.XT2, as well as affective tests for sensorial measurement. A significant correlation (‐0.90592; p ≤ 0.05) was found between friability ...

It has been shown that bacterial exoproducts may induce airway epithelium injury. During the epithelial repair process, the respiratory epithelial cells no more establish tight junctional intercellular complexes and may be particularly susceptible to bacterial virulence factors. In this study, we analyzed the effect of Pseudomonas aeruginosa exotoxin A (ETA) at different periods of time and concentrations on 16 HBE 14o(-) human bronchial epithelial cells in culture conditions inducing a phenotype ...

This study presents a first evaluation of the potential of two membrane processes for the production of concentrated camu–camu juice with high vitamin C content. A clarified camu–camu juice at around 64 g kg−1 of total soluble solids (TSS) with an average ascorbic acid content of 11 g kg−1 was subsequently concentrated by reverse osmosis and osmotic evaporation at low temperature (20–35 °C). Reverse osmosis trials were carried out in a pilot scale equipment, using a composite film membrane with 95% ...

A total of 360 Xylella fastidiosa strains were isolated from sweet orange (Citrus sinensis) cv. Pera plants growing in five geographic regions in the Brazilian state of São Paulo. The genetic variation of these strains was determined by 15 variable number tandem repeat (VNTR) and 58 random amplified polymorphic DNA (RAPD) markers. The mean values of genetic diversity (H) of X. fastidiosa strains within each geographic region determined by RAPD (H RAPD ) were substantially lower than H VNTR values. H RAPD ...

Abstract The bacteria Xylella fastidiosa is the causative agent of a number of economically important crop diseases, including citrus variegated chlorosis. Although its complete genome is already sequenced, X. fastidiosa is very poorly characterized by biochemical approaches at the protein level. In an initial effort to characterize protein expression in X. fastidiosa we used one‐ and two‐dimensional gel electrophoresis and mass spectrometry to identify the products of 142 genes present in a whole ...
