Changes on the cell wall composition of tree-ripened “Bartlett” pears (Pyrus communis L.)
(Elsevier, 2012-11)Most of the European pear cultivars fail to develop a desirable texture when ripening on the tree. In order to identify some biochemical anomalies that might be associated with this phenomenon, the main differences in cell ... -

Tobacco and end stage renal disease: a multicenter, cross-sectional study in Argentinian Northern Patagonia
(International Society for the Prevention of Tobacco Induced Diseases, 2015-09)Background: Smoking and chronic kidney disease are major public health problems with common features -high prevalence and mortality, high cardiovascular risk, gender differences and high prevalence in low income people-, ... -
An insight into the role of fruit maturity at harvest on superficial scald development in ‘Beurré D’Anjou’ pear
(Elsevier, 2015-08-31)To assess the influence of the fruit maturity at harvest on superficial scald incidence, ‘Beurré D’Anjou’ pears were harvested on January 24 (H1); February 7 (H2) and February 21 (H3). Ethylene production, α-farnesene (AF), ... -
Effect of pre and postharvest application of fungicides on postharvest decay of Bosc pear caused by Alternaria—Cladosporium complex in North Patagonia, Argentina
(Elsevier, 2017-11-18)In recent years, decays by Alternaria spp. and Cladosporium spp. constituted a hazard to “Bosc” pear fruit during cold storage with significant economic losses (about 50%) in the Rio Negro and Neuquen Valleys. Studies with ... -
Cherry fibers isolated from harvest residues as valuable dietary fiber and functional food ingredients
(Elsevier, 2014-04)Residues discarded at cherry fruit harvesting were extracted with ethanol from ‘Chelan’, ‘Brooks’ and ‘Sunburst’ varieties to obtain cherry fibers constituted by the cell wall polysaccharides, applicable as functional food ... -
