Refractory benign esophageal strictures
Authors: Goyal Gopal , Sultania Surender , Meena Babulal , Nijhawan Sandeep 
Published: April 2016

AbstractRefractory benign esophageal stricture (RBES) is a frequently encountered problem worldwide. These strictures arise from various causes such as corrosive injury, radiation therapy, peptic origin, ablative therapy, and after surgery. Most strictures can be treated successfully with endoscopic dilatation using bougies or balloons, with only a few complications. Those patients who fail after serial dilatation with bougies or balloons will come to the category of refractory strictures. Dilatation combined with intralesional steroid injections can be considered for peptic strictures, whereas incisional therapy has been demonstrated to be effective for short anastomotic strictures. When these therapeutic options do not resolve the stenosis, stent placement should be considered. Self-bougienage can be proposed to a selected group of patients with a proximal stenosis. Most of the patients of RBES respond to above-mentioned treatment and occasional patient may require surgery as the final treatment option. This review aims to provide a comprehensive approach toward endoscopic management of RBESs based on current literature and personal experience.

Abstract
Background: Carbon dioxide (CO2) insufflation has been shown to be superior to air insufflation in colonoscopy, and double balloon enteroscopy. However, the value of CO2 insufflation in endoscopic retrograde cholangiopancreatography (ERCP) is not established. This study aims to assess the efficacy and safety of CO2 insufflation during ERCP. Materials and Methods: Consecutive patients referred for ERCP at a single center were randomized to either air or CO2 insufflation during ERCP. The primary objectives were a post-ERCP abdominal pain (measured by 10 cm visual analog scale [VAS] 30 and 90 min, and 3 h and 24 h after ERCP). Secondary objectives included end-tidal CO2 (ETCO2) values and procedural complications. Results: We randomized 298 patients; 149 into air group and 149 into CO2 group. The VAS score for pain was higher in the air group compared to the CO2 group at 30 min, with a median of 1 (interquartile range 1–0) versus median of 1 (interquartile range 1–0); P = 0.031 and 90 min after the procedure with a median of 0 (interquartile range 1–0) versus median of 0 (interquartile range 0–0); P = 0.006. There were no serious adverse events, and the ETCO2 was within normal limits in both groups. Conclusions: CO2 insufflation is superior to air insufflation during ERCP with regard to patient pain and discomfort and warrants wide adoption. Clinical Trials.gov registration number NCT 01321203.

AbstractPancreatic carcinoma is a dreaded diagnosis due to its poor prognosis. Squamous cell carcinoma (SCC) of the pancreas is a rare histological variety of pancreatic carcinoma. Its diagnosis is based on ruling out other site of tumor origin. Pancreatic carcinoma can mimic as mass or cystic lesion. We report a case of primary SCC of the pancreas in a 46-year-old male that closely mimicked acute pancreatitis with walled-off pancreatic necrosis.

Fate of Conjugated and Free Estrogens in Swine Manure Collected from areas Housing Piglets, Pregnant Sows and Finisher Pigs
Authors: K. Singh Ashok 
Published: April 2016

Occurrence and fate of estrogens and their metabolites were studied in pig manure collected during winter and summer seasons from sites housing piglets (Nursery (Nur)-manure), pregnant and nursing sows (PS manure) and finisher pigs (FPig manure). The liquid and solid fractions of manure were analyzed for (1) total solids (TS), volatile solids (VS) and total organic carbon (TOC), (2) E coli and M fujisawaense enumeration, (3) total and individual estrogens and (4) estrogenic activity. This study showed that VS and OC values, E coli and M fujisawaense enumerations, estrogen concentrations and estrogenic activity exhibited the following pattern: Nur-manure << FPig-manure < PS-manure. The values for summer and winter Nur-manure did not differ significantly, while the values in summer PS-manure or FPig manure samples were significantly higher than values in corresponding winter samples. Although, estrogens distributed between liquid and solid fractions of manure, concentrations of free, but not conjugated, estrogens depended on manures’ TOC values: an increase in TOC associated with an increase in free estrogen concentrations in liquid manure. However, an increase in TOC decreased the bacterial population in manure liquid by increasing their translocation from liquid into the in solids and ensuing bacterial stabilization. This may increase estrogens’ deconjugation and/or degradation. Estrone (E1) sulfate (sE1), free E1 (fE1), E1 glucuronide (gE1) and E1 metabolites were major steroids present in Nur- and PS-manure, while fE2 and gE2 were predominant estrogens in FPig-manure. In total, the winter estrogen load in liquid was 5.1 mg/L and the load in solid was 4.93 mg/kg. Assuming that 2.3 x 108 kg of manure is produced in the USA per day, approximate hormone load will be 2.3 tons/day. However, manure contains microorganisms that hydrolyze estrogens, thus actual hormone load will be considerably lower.

Published: April 2016

Abstract
The efficiency of ultraviolet (UV) light-emitting diodes (LEDs) is critically limited by absorption losses in p-type and metal layers. In this work, surface-roughening-based light extraction structures were combined with tunneling-based top-layer contacts to achieve highly efficient top-side light extraction in UV LEDs. By using self-assembled Ni nanoclusters as an etch mask, the top surface-roughened LEDs were found to enhance the external quantum efficiency by over 40% for UV LEDs with a peak emission wavelength of 326 nm. The method described here can be used for fabricating highly efficient UV LEDs without the need for complex manufacturing techniques such as flip chip bonding.
Influence of atmospheric waves on the formation and the maintenance of the subtropical jet during the Northern Hemisphere winter—A new method for analyzing the responses to specific forcings
Authors: Kuroda Yuhji 
Published: April 2016

AbstractThis paper introduces a new analysis method that can isolate the responses to specific forcings within meteorological data. By using the zonal mean primitive equations on the sphere, it is possible to break down the meridional circulation, the acceleration of zonal wind, temperature change, and surface pressure change into their individual contributions, which are directly associated with various forcings. This analysis technique can be applied to a wide range of problems relating to climate and its variability. To demonstrate the application of the technique, the formation and maintenance of the subtropical jet during the Northern Hemisphere winter are examined. It is found that atmospheric waves play a crucial role in both the climatological maintenance and the day‐to‐day (and month‐to‐month) variabilities of the jet. While stationary waves are the dominant catalyst for maintaining the jet in its climatological state, synoptic waves play an important role in generating the month‐to‐month variability of the jet.
Large‐scale ocean circulation‐cloud interactions reduce the pace of transient climate change

Published: April 2016

AbstractChanges to the large‐scale oceanic circulation are thought to slow the pace of transient climate change due, in part, to their influence on radiative feedbacks. Here we evaluate the interactions between CO2‐forced perturbations to the large‐scale ocean circulation and the radiative cloud feedback in a climate model. Both the change of the ocean circulation and the radiative cloud feedback strongly influence the magnitude and spatial pattern of surface and ocean warming. Changes in the ocean circulation reduce the amount of transient global warming caused by the radiative cloud feedback by helping to maintain low cloud coverage in the face of global warming. The radiative cloud feedback is key in affecting atmospheric meridional heat transport changes and is the dominant radiative feedback mechanism that responds to ocean circulation change. Uncertainty in the simulated ocean circulation changes due to CO2 forcing may contribute a large share of the spread in the radiative cloud feedback among climate models.
Tectonic evolution of a Laramide transverse structural zone: Sweetwater Arch, south central Wyoming
Authors: Weil Arlo Brandon , Yonkee Adolph , Schultz Mary 
Published: April 2016

AbstractStructural, anisotropy of magnetic susceptibility (AMS), and paleomagnetic data record patterns of layer‐parallel shortening (LPS), vertical‐axis rotation, and regional fault‐fold evolution across the Sweetwater Arch, a major west to WNW trending, basement‐cored Laramide uplift in Wyoming. The southern arch flank is bounded by a WNW striking reverse fault zone that imbricated basement and cover rocks, the northern flank is bounded by a west striking fault zone with a component of strike‐slip and NW trending en echelon folds, and the eastern plunge transitions into an area of multiple‐trending faults and folds. Synorogenic strata record major arch uplift from Maastrichtian to Early Eocene time, followed by arch collapse. LPS, with development of systematic minor fault sets and AMS lineations, preceded large‐scale folding. LPS directions, estimated from both minor fault and AMS data, were oriented WSW along the northern flank, subparallel to Laramide regional shortening, but were refracted to the SSW along the southern flank, and to the west along the eastern arch plunge. Additional minor faults developed along steep fold limbs during continued shortening, with directions remaining SSW along the southern flank but becoming more variable along the eastern plunge where an increasingly heterogeneous stress field developed as additional faults were activated along basement heterogeneities. Vertical‐axis rotation was limited along the arch flanks, whereas the eastern plunge underwent counterclockwise rotation. Deflections in shortening directions were partly related to basement heterogeneities, including weak supracrustal belts on the arch flanks, a strong granitic core, and local reactivation of Precambrian shear zones.
