Drugs that treat acid reflux or heartburn raise the pH environment of the upper GI tract, which reduces absorption of needed vitamins and minerals.
Following the intake of a food product containing L. monocytogenes, the pathogen is exposed to the acidic environment of the upper GI tract.
Several factors affect how many, if any, L. monocytogenes survive the acidic environment of the upper GI tract, including the food matrix, the quantity and composition/acidity of foods consumed, and the general level of acidity in the GI tract.
The relatively lower GC content of HRV-B may reflect an adaptation to the environment of the upper respiratory tract, whereas the higher GC content of HEVs might reflect convergent adaptation to the gastrointestinal tract of the central nervous system environment (such as higher temperature, acidity, etc).
MET with thirteen rape genotypes (QS101 QS113) and randomized complete block design at each test environment for the upper reaches of the Yangtze River of China.
This led to the creation of a new high-altitude niche, and the very different environments of the mountain's upper and lower slopes created strong divergent selection between the plants growing in the two habitats and they subsequently diverged, although gene flow persisted.
Another mutation, in the polymerase protein complex, allows the virus to replicate in the cool environment of the human upper respiratory tract rather than in bird intestines, the much warmer environment where it usually resides.
In the case of a heterogeneous hardware environment, the services of the upper layers of the OSI communication standard are utilized in the chapter.
In addition to seizure-induced changes in the hippocampal environment, the degeneration of the upper blade following fluid injection may increase the expression of factors that may influence the fates of transplanted cells.
From the top to the base of the sequence, the Triassic is characterized by lagoonal environments (Keuper), marine-to-lagoonal environments (Muschelkalk) and fluvial (lower Buntsandstein) to fluvio-deltaic environments in the upper part of the Buntsandstein (Grès à Voltzia).
