Cell migration is a fundamental process in all animal cells. The ability of cell to migrate is crucial for many pathological and physiological conditions such as morphogenesis, the immune response to inflammatory or vascular diseases and cancer metastasis. ...
Thymic stromal lymphopoietin (TSLP) is constitutively expressed in the intestine and is known to regulate inflammation in models of colitis. We show that steady-state TSLP expression requires intestinal bacteria and has an important role in limiting the ex ...
Cultivation-independent microbial molecular ecology approaches were used to examine the effects of antibiotic growth promoters on the pig ileal microbiota. Five-week-old barrows were fitted with a simple T-cannula at the distal ileum. Three diets meeting o ...
Nef, a multifunctional HIV protein, activates the Vav/Rac/p21-activated kinase (PAK) signaling pathway. Given the potential role of this pathway in the activation of the phagocyte NADPH oxidase, we have investigated the effect of the HIV-1 Nef protein on t ...
Necrotic enteritis (NE) is a worldwide poultry disease caused by the alpha toxin-producing bacterium Clostridium perfringens. Disease risk factors include concurrent coccidial infection and the dietary use of cereal grains high in nonstarch polysaccharides ...
Despite major attempts to prevent cholera transmission, millions of people worldwide still must address this devastating disease. Cholera research has so far mainly focused on the causative agent, the bacterium Vibrio cholerae, or on disease treatment, but ...
The first members of the tiacumicin family of antibiotics, encompassing more than 40 compounds, were isolated in 1975. Structurally, the core aglycon is an 18-membered macrolactone having two conjugated diene units, one isolated double bond, 5 stereogenic ...
The first examples of macrocyclization using the intramol. SNAr reaction are reported. The method has allowed the efficient prepn. of the elusive 16-membered macrocyclic COD and DOE rings related to vancomycin. The mild conditions used allow the incorporat ...
We have studied low-temperature magnetic properties as well as high-temperature lithium ion diffusion in the battery cathode materials LixNi1/3Co1/3Mn1/1O2 by the use of muon spin rotation/relaxation. Our data reveal that the samples enter into a 2D spin-g ...
BACKGROUND: Compromised barrier function and intestinal inflammation are common complications of total parenteral nutrition (TPN). OBJECTIVE: We tested the hypothesis that the lack of enteral nutrients in TPN might select commensal or pathogenic bacteria t ...
