Objective： Curative gastric cancer surgery entails removal of the primary tumor with adequate margins including regional lymph nodes. European randomized controlled trials with recruitment in the 1990＇s reported increased morbidity and mortality for D2 compared to D 1. Here, we examined the extent of lymphadenectomy during gastric cancer surgery and the associated risk for postoperative complications and mortality using the strengths of a population-based study. Methods： A prospective nationwide study conducted within the National Register of Esophageal and Gastric Cancer. All patients in Sweden from 2006 to 2013 who underwent gastric cancer resections with curative intent were included. Patients were categorized into DO, D I, or D I ＋/D2, and analyzed regarding postoperative morbidity and mortality using multivariable logistic regression. Results： In total, 349 （31.7%） patients had a DO, 494 （44.9%） DI, and 258 （23.4%） DI＋/D2 lymphadenectomy. The 30-d postoperative complication rates were 25.5%, 25.1% and 32.2 % （DO, D I and D1 ＋/D2, respectively）, and 90-d mortality rates were 8.3%, 4.3 % and 5.8%. After adjustment for confounders, in mukivariable analysis, there were no significant differences in risk for postoperative complications between the lymphadenectomy groups. For 90-d mortality, there was a lower risk for D1 vs. DO. Conclusions： The majority of gastric cancer resections in Sweden have included only a limited lymphadenectomy （DO and DI）. More extensive lymphadenectomy （DI＋/D2） seemed to have no impact on postoperative morbidity or mortality.

The use of consecutive feeding was applied to investigate the response of the microbial biomass to a second addition of substrates in terms of biodegradation using batch tests as a promising alternative to predict the behavior of the process. Anaerobic digestion（AD） of the slaughterhouse waste（SB） and its co-digestion with manure（M）, various crops（VC）, and municipal solid waste were evaluated. The results were then correlated to previous findings obtained by the authors for similar mixtures in batch and semi-continuous operation modes. AD of the SB failed showing total inhibition after a second feeding. Co-digestion of the SB ＋ M showed a significant improvement for all of the response variables investigated after the second feeding, while co-digestion of the SB ＋ VC resulted in a decline in all of these response variables. Similar patterns were previously detected, during both the batch and the semi-continuous modes.

Objective: To characterise a novel multifunctional pharmaceutical excipient and investigate its ef ect on paracetamol release from tablets prepared by direct ***: The excipient was prepared by co-processing gelatinized maize starch with sodium carboxymethyl cellulose and microcrystalline cellulose in a ratio of 2:1:1, dried and pulverized into powder. The excipient formulated was characterized using Fourier transform infrared spectroscopy and dif erential scanning calorimetry. The excipient was used to prepare batches of tablets by direct compression with drug-excipient ratios of 1:1, 1:2, 1:3 and 1:4. Parameters evaluated on tablets include crushing strength, friability and in vitro dissolution studies. Results: Differential scanning calorimetry analysis revealed a crystalline excipient while Fourier transform infrared spectroscopy showed no interaction between the excipient and paracetamol. Tablets from all the batches gave average crushing strength values between 3.47 and 4.88 kp. The 1:1 and 1:2 tablet batches were comparable to each other while 1:3 and 1:4 were also comparable to one another in their dissolution proi les. The dissolution parameters of the 1:4 batch was faster with- m∞(90.5%), t50%(3.5 min), t70%(11.6 min) while that of ratio 1:1 was the least with- m∞(48.6%), m5min(23.8%). Their release kinetics followed a KorsmeyerPeppas model with a super case-II transport ***: The drug-excipient ratios of 1:3 and 1:4 gave pharmaceutically acceptable tablets that met the British Pharmacopoeia specii cations. The t50% value of the 1:4 batch of tablets may i nd its usefulness in formulating drugs for which a fast onset of action is desired.

We report a method using in situ etching to decouple the axial from the radial nanowire growth pathway,independent of other growth *** a wide range of growth parameters can be explored to improve the nanowire properties without concern of tapering or excess structural defects formed during radial *** demonstrate the method using etching by HCl during InP nanowire *** improved crystal quality of etched nanowires is indicated by strongly enhanced photoluminescence as compared to reference nanowires obtained without etching.
