Coconut Flour (Cocos nucifera L.) as a Partial Replacement in Wheat Flour (Triticum aestivum)-Based Tortillas and Its Effect on Dough Rheology and Tortilla Quality.

Wheat-flour (WF) tortillas are among the popular flatbreads used in northern Mexico to prepare 'burritos', which are widely accepted in the USA and other countries but have low nutritional quality. Therefore, to increase the protein and fiber contents, we replaced 10 or 20% of the WF with coconut (Cocos nucifera, variety Alto Saladita) flour (CF) and evaluated the effects on the dough rheology and quality of the composite tortillas. There were differences in the optimum mixing times among the doughs.

Identification of Allergenic Proteins in Velvet Mesquite () Pollen: An Immunoproteomics Approach.

Velvet mesquite () is a native legume of the southwestern United States and northwestern Mexico, contributing significantly to the desert ecosystem and playing key ecological roles. It is also an important cause of allergic respiratory disease widely distributed in the Sonoran, Chihuahuan, and Mojave Deserts. However, no allergens from velvet mesquite pollen have been identified to date.

New Insights into the Mechanism of Action of PirAB from Vibrio Parahaemolyticus.

PirAB toxins secreted by () harbor the pVA1 virulence plasmid, which causes acute hepatopancreatic necrosis disease (AHPND), an emerging disease in Penaeid shrimp that can cause 70-100% mortality and that has resulted in great economic losses since its first appearance. The cytotoxic effect of PirAB on the epithelial cells of the shrimp hepatopancreas (Hp) has been extensively documented. New insights into the biological role of the PirB subunit show that it has lectin-like activity and recognizes mucin-like O-glycosidic structures in the shrimp Hp.

The Vibrio parahaemolyticus subunit toxin PirB recognizes glycoproteins on the epithelium of the Penaeus vannamei hepatopancreas.

Vibrio parahaemolyticus toxin PirAB is the major virulence factor exotoxin that contributes to the disruption of the hepatopancreatic epithelium in acute hepatopancreatic necrosis disease in shrimp. The PirB subunit is a lectin that recognizes amino sugars; however, its potential role in recognition of the hepatopancreas has not been identified. In the present work, we identified the cellular receptor for PirB in the shrimp hepatopancreas.

Immunoproteomic identification of allergenic proteins in pecan (Carya illinoinensis) pollen.

Pecan (C. illinoinensis) pollen is an important cause of allergic respiratory disease. Pecan is distributed worldwide as shade, ornamental or cultivation tree.
