Host-Derived Sialic Acids Are an Important Nutrient Source Required for Optimal Bacterial Fitness In Vivo
UNLABELLED A major challenge facing bacterial intestinal pathogens is competition for nutrient sources with the host microbiota.Vibrio cholerae is an intestinal pathogen that causes cholera, which affects millions each year; however, our knowledge of its nutritional requirements in the intestinal milieu is limited. In this study, we demonstrated that V. cholerae can grow efficiently on intestin...
متن کاملEtiology of Thickened Pituitary Stalks

These disorders can be classified as neoplastic, inflammatory, or infectious in origin, although there are rare forms of congenital malform...
متن کاملOn Generic Stalks of Sheaves
Sheaf theoretic notions and methods have entered model theory during recent years and important constructions like reduced powers and products, unions of chains, Boolean valued models and models for non-classical logics appear here in a unified setting. If one looks at a sheaf as a generalized structure, then forcing becomes the genuine extension of the validity relation between models and form...
متن کاملSelective detection of bacterial layers with terahertz plasmonic antennas
Current detection and identification of micro-organisms is based on either rather unspecific rapid microscopy or on more accurate but complex and time-consuming procedures. In a medical context, the determination of the bacteria Gram type is of significant interest. The diagnostic of microbial infection often requires the identification of the microbiological agent responsible for the infection...
متن کاملRamadan major nutrient patterns are associated with anthropometric measurements and physical activity in Tehran, Iran
During Ramadan fasting quantity and quality of dietary intake may change. There was no data on nutrient patterns in Ramadan fasting. The purpose of this study was to identify Ramadan major nutrient patterns among those who fast in Tehran, Iran. 510 fasting people aged 18-65 years and BMI 18.5-40 Kg/m2 were recruited in our study by 2-stage cluster sampling method in June-July 2014. Data on the ...
