Abstract:
Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disorder in the esophagus characterized by symptoms related to esophageal dysfunction and eosinophil-predominant inflammation. EoE and Gastro Esophageal Reflux Disease (GERD) are known not to be mutually exclusive and share a complex relationship. Proton pump inhibitors (PPIs), which are generally used in the treatment of GERD, could be used to treat esophageal eosinophilia in suspected EoE. We report a rare case of EoE after total gastrectomy that responded to PPIs. Our case indicates that the onset of EoE does not necessarily require an acid reflux-induced antigen-mediated drive, and the action of PPIs in patients with active EoE is unrelated to gastric acid suppression.

ATP Driven Pumps II: P-type Pumps
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...

Pumped Concrete
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...
