sists mainly of collagen, hyaluronan, and proteoglycan. During gestation, it must close firmly to retain the fetus in the uterus. It undergoes ripening and dilatation at term, forming a parturient canal so that delivery can occur. During ripening, there are increases of collagen degradation in connective tissues, and proteoheparan sulfate, while decorin decreases. Inflammatory mediators, such a...

BACKGROUND To clarify whether the use of balloons for cervical ripening is associated with the incidence of umbilical cord prolapse. METHODS A postal questionnaire survey was distributed in Japan. Cases of umbilical cord prolapse occurring during labor in association with the use of balloons for cervical ripening between 2007 and 2011 in Japan were analyzed. RESULTS Answers from 942 institu...

Tomato (Lycopersicon esculentum) fruit ripening is initiated by an increase in ethylene hormone concentration. E8 gene transcription is fruit-specific and is activated at the onset of ripening and in unripe fruit treated with exogenous ethylene. To understand how E8 gene transcription is controlled during ripening, we analyzed the effect of deletions of flanking DNA sequences on E8 gene express...

The interactive effects of aeration rate, storage temperature, harvest maturity, and storage duration on respiration and ripening of tomato fruits (Lycopersicum esculentum var. Roma) were studied. Slow aeration rate strongly reduced the climacteric but did not affect ripening. Low temperature slowed ripening and reduced respiratory rates, but low temperature did not delay attainment of the clim...

increasing incidence of food-borne disease along with its social and economic consequences have led to conducting extensive research in order to produce safer food and develop new antimicrobial agents; among them, extensive use of probiotics and bacteriocins as biological additives is of significant importance. the aim of the present study was to evaluate the interactions (growth behavior and s...

Analyses of the protein content and composition revealed dramatic changes in gene expression during in situ banana (Musa spp.) fruit formation/ripening. The total banana protein content rapidly increases during the first 60 to 70 d, but remains constant for the rest of fruit formation/ripening. During the phase of rapid protein accumulation, an inactive homolog of class III chitinases accounts ...

The pH of cheese is an important attribute that influences its quality. Substantial changes in cheese pH are often observed during ripening. A combined effect of calcium, phosphorus, residual lactose, and salt-to-moisture ratio (S/M) of the cheese on the changes in cheese pH during ripening was investigated. Eight cheeses with 2 levels of Ca and P (0.67 and 0.47% vs. 0.53 and 0.39%, respectivel...

Enzymically active cell wall from ripe tomato (Lycopersicon esculentum Mill.) fruit pericarp release uronic acids through the action of wall-bound polygalacturonase. The potential involvement of products of wall hydrolysis in the induction of ethylene synthesis during tomato ripening was investigated by vacuum infiltrating preclimacteric (green) fruit with solutions containing pectin fragments ...
