The expression of heterologous MAM-7 in Lactobacillus rhamnosus reduces its intrinsic capacity to inhibit colonization of pathogen Vibrio parahaemolyticus in vitro.
(CIENCIAS, 2016)BACKGROUND: Vibrio parahaemolyticus (V. parahaemolyticus) is a Gram-negative, halophilic bacterium recognized as one of the most important foodborne pathogen. When ingested, V. parahaemolyticus causes a self-limiting illness ... -
The use of cortical particulate allograft mixed with plasma-rich fibrin in severe maxillary alveolar ridge atrophy
(CIENCIAS, 2016)Atrophy in the edentulous maxilla typically consists of vertical bone loss in the posterior maxilla due to pneumatization of the maxillary floor and transverse reduction in anterior areas. The purpose of this study was to ... -
Use of Fura 2 Fluorescent Dyes as Indicator for Studying Calcium Distribution in Several Plant Tissues
(CIENCIAS, 2010)Calcium (Ca) is an essential plant nutrient and is important in determining quality of fruits in storage. The analytical method presently known to determine Ca concentration in vegetables measures total Ca, and there is a ... -
Thermal remote sensing of ice-debris landforms using ASTER: an example from the Chilean Andes
(CIENCIAS, 2012)Remote sensors face challenges in characterizing mountain permafrost and ground thermal conditions or mapping rock glaciers and debris-covered glaciers. We explore the potential of thermal imaging and in particular thermal ... -
