The ulcer-causing gastric pathogen Helicobacter pylori is the only bacterium known to
colonize the harsh acidic environment of the human stomach. H. pylori survives in acidic …

BACKGROUND & AIMS: Helicobacter pylori adheres to gastric epithelial cells and stimulates
interleukin (IL)-8 production. This may be instrumental in neutrophil infiltration of the gastric …

Partial or even complete cancer regression can be achieved in some patients with current
cancer treatments. However, such initial responses are almost always followed by relapse, …

The aim of this study was to determine whether Helicobacter pylori activates mitogen-activated
protein (MAP) kinases in gastric epithelial cells. Infection of AGS cells with an H. pylori cag…

Background & aims: Recurrent C difficile-associated diarrhea (CDAD) is associated with a
lack of protective immunity to C difficile toxins. A parenteral C difficile vaccine containing …

Saccharomyces boulardii (Sb) is a non-pathogenic yeast that ameliorates intestinal injury and
inflammation caused by a wide variety of enteric pathogens. We hypothesized that Sb may …

Clostridium difficile toxin A causes acute neutrophil infiltration and intestinal mucosal injury.
In cultured cells, toxin A inactivates Rho proteins by monoglucosylation. In monocytes, toxin …

The gastric pathogen Helicobacter pylori is known to activate epithelial cell signaling
pathways that regulate numerous inflammatory response genes. The aim of this study was to …

Axenic Pistia stratiotes L. plants were pulse-chase labeled with [ 14 C ]oxalic acid, L-[1- 14
C ]ascorbic acid, L-[6- 14 C ]ascorbic acid, D-[1- 14 C ]erythorbic acid, L-[1- 14 C ]galactose, …

Neutrophil infiltration is central to the pathogenesis of Clostridium difficiletoxin A-induced
enterocolitis. This study examines whether monocyte activation by C. difficile toxins is …
