04 and p = 0.003, respectively). The presence of chronic otitis findings were significantly increased in both groups (p = 0.00). Statistical significance was set at p < 0.05.
Conclusion: Our findings suggest that mastoid cell volumes tend to be larger at the contralateral side of the severe septum deviations.”
“BACKGROUND: Fructooligosaccharides
are important check details sweeteners produced by sucrose biotransformation. Although fructooligosccharides production has been reported widely, most studies have been carried out at laboratory level. This study evaluates semibatch and continuous fructooligosaccharides production by Aspergillus sp. N74 at bench scale in a mechanically agitated airlift.
RESULTS: ABT-263 Sucrose biotransformation to fructooligosaccharides was carried out with biomass harvested after 24 or 48 h of culture. For 6.21 +/- 0.33 or 9.66 +/- 0.62 g biomass dry weight L(-1), the highest FOS yields were obtained at batch operating 62.1 and 66.4% after 26 or 6 h of reaction, respectively. Reduction in fructooligosaccharides yield was observed for both biomass concentrations at semibatch operating, while a comparable yield was obtained during continuous operating (62.1% for 6.21 +/- 0.33 g L(-1) and a dilution rate 0.016 s(-1), and 62.8% for 9.66 +/- 0.62 g L(-1) and a dilution rate 0.032 s(-1)). Nevertheless, 1-kestose formation was favored with biomass harvested
after 24 h under any operating mode.
CONCLUSION: Biomass concentration, reaction time and operating mode have a notable effect on fructooligosaccharides yield and composition. 1-kestose, Selleckchem MLN4924 the most valuable fructooligosaccharide, was obtained in greatest proportion at a biomass concentration 6.21 +/- 0.33 g L(-1). Under the different operating modes, Aspergillus
sp. N74 mycelia and the reactor described are presented as a feasible alternative for scaling up fructooligosaccharides production. (C) 2008 Society of Chemical Industry”
“ObjectiveTo determine the effect of perinatal exposure to low doses of genistein and/or vinclozolin on submandibular salivary gland (SSG) development in juvenile and adult male rats and to establish a link with sweet preference.
Material and MethodsFemale rats received orally (1mgkg(-1) body weight/day) genistein and vinclozolin, alone or in combination, from the first gestational day up to weaning. Sweet preference was assessed at weaning and in adulthood in male offspring; submandibular glands were then collected to study the morphogenesis and mRNA expression of steroid receptors, growth factors and taste related proteins.
ResultsExposure to genistein and/or vinclozolin resulted in a higher saccharin intake on postnatal day 25 (P<0.05) linked to a higher number of pro-acinar cells (P<0.01) and mRNA expression of progesterone receptor, growth factors and gustine (P<0.01).
