This finding suggests a significant incremental benefit of prophylactic PPI in reducing marginal ulcer after gastric bypass surgery. Prospective randomized trials are needed to further define the role of PPI following gastric bypass surgery.

Live cell fluorescence microscopy using fluorescent protein tags derived from jellyfish and coral species has been a successful tool to image proteins and dynamics in many species. Multi-colored aequorea fluorescent protein (AFP) derivatives allow investigators to observe multiple proteins simultaneously, but overlapping spectral properties sometimes require the use of sophisticated and expensive microscopes. Here, we show that the aequorea coerulescens fluorescent protein derivative, PS-CFP2 has excellent practical properties as a blue fluorophore that are distinct from green or red fluorescent proteins and can be imaged with standard filter sets on a widefield microscope. We also find that by widefield illumination in live cells, that PS-CFP2 is very photostable. When fused to proteins that form concentrated puncta in either the cytoplasm or nucleus, PSCFP2 fusions do not artifactually interact with other AFP fusion proteins, even at very high levels of over-expression. PSCFP2 is therefore a good blue fluorophore for distinct three color imaging along with eGFP and mRFP using a relatively simple and inexpensive microscope.

Patients with incarcerated abdominal hernias who underwent laparoscopic repair had a significantly lower 30-day morbidity compared to patients with open repair. Although the 30-day reoperation and mortality rates were also lower, there was no statistically significant difference. Laparoscopic surgery appears to be safe in the management of select incarcerated abdominal hernias.
