TL;DR: The STREGA recommendations do not prescribe or dictate how a genetic association study should be designed but seek to enhance the transparency of its reporting, regardless of choices made during design, conduct, or analysis.
Abstract: Making sense of rapidly evolving evidence on genetic associations is crucial to making genuine advances in human genomics and the eventual integration of this information in the practice of medicine and public health. Assessment of the strengths and weaknesses of this evidence, and hence the ability to synthesize it, has been limited by inadequate reporting of results. The STrengthening the REporting of Genetic Association studies (STREGA) initiative builds on the STrengthening the Reporting of OBservational Studies in Epidemiology (STROBE) Statement and provides additions to 12 of the 22 items on the STROBE checklist. The additions concern population stratification, genotyping errors, modelling haplotype variation, Hardy-Weinberg equilibrium, replication, selection of participants, rationale for choice of genes and variants, treatment effects in studying quantitative traits, statistical methods, relatedness, reporting of descriptive and outcome data, and the volume of data issues that are important to consider in genetic association studies. The STREGA recommendations do not prescribe or dictate how a genetic association study should be designed but seek to enhance the transparency of its reporting, regardless of choices made during design, conduct, or analysis.

TL;DR: The purpose of this survey is to provide a framework for placing existing works in perspective and highlight critical open challenges to serve as a springboard for researchers in database systems.
Abstract: Preferences have been traditionally studied in philosophy, psychology, and economics and applied to decision making problems. Recently, they have attracted the attention of researchers in other fields, such as databases where they capture soft criteria for queries. Databases bring a whole fresh perspective to the study of preferences, both computational and representational. From a representational perspective, the central question is how we can effectively represent preferences and incorporate them in database querying. From a computational perspective, we can look at how we can efficiently process preferences in the context of database queries. Several approaches have been proposed but a systematic study of these works is missing. The purpose of this survey is to provide a framework for placing existing works in perspective and highlight critical open challenges to serve as a springboard for researchers in database systems. We organize our study around three axes: preference representation, preference composition, and preference query processing.

TL;DR: The formation of volatile amines during chill storage of chicken meat, under the packaging conditions examined in the present study, seemed to be in good agreement with the increase in microbiological count (TVC) and sensory taste score except for the M2 gas mixture.

TL;DR: The results suggest that free radicals are generated at the end of a laparoscopic procedure, possibly as a result of an ischemia-reperfusion phenomenon induced by the inflation and deflation of the pneumoperitoneum.
Abstract: Background: The induction of the pneumoperitoneum increases intraabdominal pressure (IAP), causing splanchnic ischemia, whereas its deflation normalizes IAP and splanchnic blood flow. This procedure appears to represent an ischemia-reperfusion model in humans. Methods: Thirty laparoscopic cholecystectomies (LC) were performed in 30 patients with a mean age of 54.6 ± 15.6 years. A group of 20 patients mean age, 57.3 ± 9.65 who underwent open cholecystectomy (OC) was also studied. Vein plasma levels of thiobarbituric acid-reactive substances (TBARS), a marker of free radical production; plasma total antioxidant status (TAS); and uric acid (UA) levels were measured preoperatively, 5 min after deflation of the pneumoperitoneum or at the end of operation, and 24 h postoperatively. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin (TBL) levels were measured preoperatively and 24 h after the operation. Results: In the LC group, significant elevations in the concentration of TBARS were observed in the early postoperative measurements in comparison with the preoperative measurements. TAS and UA levels were decreased significantly 24 h postoperatively compared to preoperative levels. The postoperative levels of AST, ALT, and TBL increased significantly in comparison with the preoperative levels. In the OC group, no alterations in the concentration of TBARS were observed in the postoperative period. The other parameters had changes similar to those recorded for the LC group. Conclusions: Free radical-induced lipid peroxidation associated with a decrease in plasma antioxidant capacity and UA levels as well as altered hepatic function is observed after deflation of the pneumoperitoneum. These results suggest that free radicals are generated at the end of a laparoscopic procedure, possibly as a result of an ischemia-reperfusion phenomenon induced by the inflation and deflation of the pneumoperitoneum.
