AIM To evaluate the association between acid suppressive drug use and the development of gastric cancer. METHODS A systematic search of relevant studies that were published through June 2012 was conducted using the MEDLINE (PubMed), EMBASE, and Cochrane Library databases. The search included observational studies on the use of histamine 2-receptor antagonists (H₂RAs) or proton pump inhibitors...

The newly described green-pigmented bacterium Pseudoalteromonas tunicata (D2) produces target-specific inhibitory compounds against bacteria, algae, fungi, and invertebrate larvae and is frequently found in association with living surfaces in the marine environment. As part of our studies on the ecology of P. tunicata and its interaction with marine surfaces, we examined the ability of P. tunic...

The site-specific recombination pathway by which the bacteriophage k chromosome is excised from its Escherichia coli host chromosome is a tightly regulated, highly directional, multistep reaction that is executed by a series of multiprotein complexes. Until now, it has been difficult to study the individual steps of such reactions in the context of the entire pathway. Using single-molecule ligh...

OBJECTIVE This study was undertaken to determine if the use of formal guidelines in selecting the route of hysterectomy would improve medical and economic outcomes. METHOD Data from 4595 hysterectomies performed at a single center in women whose primary diagnosis were unrelated to invasive cancer or pregnancy were analyzed in terms of mean, uterine weight, costs, length of stay, and complicat...

Personality traits have been shown to be associated with longevity and healthy aging. In order to discover novel genetic modifiers associated with personality traits as related with longevity, we performed a genome-wide association study (GWAS) on personality factors assessed by NEO-five-factor inventory in individuals enrolled in the Long Life Family Study (LLFS), a study of 583 families (N up...

BACKGROUND The Antiarrhythmics Versus Implantable Defibrillators (AVID) Study compared treatment with implantable cardioverter-defibrillators versus antiarrhythmic drugs in patients with life-threatening ventricular arrhythmias (VAs). AVID maintained a Registry on all patients, randomized or not, with any VA or unexplained syncope who could be considered for either of the treatment strategies. ...

Endothelial cells (ECs) presenting minor histocompatibility antigen (mhAg) are major target cells for alloreactive effector CD8 T cells during chronic transplant rejection and graft-versus-host disease (GVHD). The contribution of ECs to T-cell activation, however, is still a controversial issue. In this study, we have assessed the antigen-presenting capacity of ECs in vivo using a transgenic mo...
