Micronized whole wheat flour and xylanase application: dough properties and bread quality.

The micronization process by jet mill of whole wheat flour in addition to xylanase application may be used to improve dough properties and baking quality. This study aimed to evaluate the dough formation and bakery performance of whole wheat flour micronized using jet mill and having different particle sizes and xylanase content A decrease in particle size increased water absorption and increased dough stability by 3.7 units.

Pesticide and trace element bioaccumulation in wild owls in Brazil.

Owls are outstanding environmental quality bioindicators due to their position at the top of the food chain and susceptibility to pollutant accumulation. Exposure to chemical contaminants is often a risk for these animals. Moreover, studies addressing the bioaccumulation of trace elements and pesticide residues in tropical nocturnal raptor species are scarce.

Phenolic compounds and free sulfhydryl groups in whole grain wheat flour modified by xylanase.

Background: Knowledge of the structural behavior of dough elaborated using whole grain wheat flour (WGWF) and xylanase is fundamental for the elaboration of products with high nutritional content, especially when the particle size of the flour is altered. In the present study, we investigated the effect of varying concentrations of xylanase on the formation of dough with different particle sizes of WGWF.

Results: Phenolic compounds, fibers and proteins are the components that undergo the most change and interfere with dough formation.

Reduced expression of selective immune-related genes in silver catfish (Rhamdia quelen) monocytes exposed to atrazine.

The effect of atrazine (ATZ) and its metabolites on aquatic vertebrate species has been a matter of concern to researchers and environmentalist. In this study we exposed head kidney monocytes to sublethal concentrations of atrazine (1 and 10 μg/ml), corresponding to 1% and 10% of the LC, to evaluate the expression of immune-related genes central to immune stimulation. The mRNA levels of TNF-α, Mieloperoxidase and Mx genes were significantly reduced following 24 h exposure to both concentrations of ATZ.

Analytical Stability-Indicating Methods for Alogliptin in Tablets by LC-CAD and LC-UV.

Stability-indicating LC methods using a UV detector and a charged aerosol detector (CAD) simultaneously were validated for the assessment of alogliptin (ALG) in tablets. The analysis was performed on a C8 column (250 × 4.6 mm, 5 μm) at a flow of 0.

Environmental and Pharmacological Manipulations Blunt the Stress Response of Zebrafish in a Similar Manner.

Here we provide evidence that both pharmacological and environmental manipulations similarly blunt the cortisol release in response to an acute stressor in adult zebrafish. Different groups of fish were maintained isolated or group-housed in barren or enriched tanks, and then exposed or not to diazepam or fluoxetine. Acute stress increased cortisol levels in group-housed zebrafish maintained in barren environment.
