BACKGROUND: Discrepancies have been reported in the prevalence rate of restless legs syndrome (RLS) among different ethnic groups and geographic populations. Furthermore, there are disagreements on determinant factors and associated comorbidities of RLS. We aimed to estimate prevalence of RLS and investigate its associated comorbid conditions and risk factors in a large population-based door-to-door survey. METHODS: Following a multistage random sampling from the households lived in 22 urban districts of Tehran, Iran, 19176 participants with ≥30 years of age were recruited...

Overconsumption of energy dense foods and sedentary lifestyle are considered as major causes of obesity-associated insulin resistance and abnormal glucose metabolism. Results from both cohort studies and randomized trials suggested that anthocyanins from berries may lower metabolic risks, however these reports are equivocal. The present study was designed to examine effects of six berries with structurally diverse anthocyanin profiles (normalized to 400 µg/g total anthocyanin content) on development of metabolic risk factors in the C57BL/6 mouse model of polygenic obesity...

During the display of peptide/human leukocyte antigen (HLA) -I complex for further immune recognition, the cleaved and transported antigenic peptides have to bind to HLA-I protein and the binding affinity between peptide epitopes and HLA proteins directly influences the immune recognition ability in human beings. Key factors affecting the binding affinity during the generation, selection and presentation processes of HLA-I complex have not yet been fully discovered. In this study, a new method describing the HLA class I-peptide interactions was proposed...

Surgical resection is the treatment of choice for intrahepatic cholangiocarcinoma (IHCC). However, discrepancies between preoperative workup and intraoperative findings can occur, resulting in unexpected and unfavorable surgical outcomes. The aim of this study was to develop a feasible preoperative nomogram to predict futile resection of IHCC. A total of 718 patients who underwent curative-intent surgery for IHCC between January 2005 and December 2014 were included. The patients were divided into a training cohort (2005-2010, n = 377) and validation cohort (2011-2014, n = 341)...

Brynn Roach, Tony R Walker
Aquatic monitoring programs are imperative for the functioning of the environmental impact assessment (EIA) process and a cornerstone for industrial compliance in Canada. However, in 2012, several leading pieces of federal environmental legislation (e.g., Canadian Environmental Assessment Act c.19, s. 52, 2012) were drastically altered, effectively weakening levels of environmental protection for aquatic ecosystems during project developments. This paper assesses the impact of CEAA 2012 on aquatic monitoring programs (and subsequent monitoring data reporting) across Canada for ten projects (five completed pre-CEAA 2012 and five completed post-CEAA 2012)...

BACKGROUND: Handling of breast specimen is not well monitored and there is limited data on the impact of fixative solutions on specimen weights. Weight of resected breast tissue acts as a guide for future reconstructive and symmetrisation procedures. The aim is to quantitatively evaluate the discrepancies in weight of fresh breast specimen and the weight of specimen after being kept in a fixative solution for a variable length of time. METHODS: Single centre retrospective cohort study including patients undergone breast surgery for both diagnostic and therapeutic purposes between January of 2013 and June 2015...

Bilateral Neck of Femur (NOF) fractures is relatively rare. Surgery, either osteosynthesis or hemireplacement arthroplasty, is the mainstay of treatment. Significant complications are known to occur in such cases. In this case report, we present the functional outcome of a conservatively treated bilateral NOF fracture at one year, in a 93-year-old man. Our patient, a 93-year-old gentleman, sustained right side NOF fracture in May 2014 and left side NOF fracture in May 2015, both after trivial fall. He did not give consent for surgery considering high operative risk...

We investigate the q-voter model with stochastic noise arising from independence on complex networks. Using the pair approximation, we provide a comprehensive, mathematical description of its behavior and derive a formula for the critical point. The analytical results are validated by carrying out Monte Carlo experiments. The pair approximation prediction exhibits substantial agreement with simulations, especially for networks with weak clustering and large average degree. Nonetheless, for the average degree close to q, some discrepancies originate...

Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) is a universally used method for determining approximate molecular weight (MW) in protein research. Migration of protein that does not correlate with formula MW, termed "gel shifting" appears to be common for histidine-rich proteins but not yet studied in detail. We investigated "gel shifting" in Ni2+-binding histidine-rich Hpn protein cloned from Helicobacter pylori strain SS1. Our data demonstrate two important factors determining "gel shifting" of Hpn, polyacrylamide-gel concentration and metal binding...

In the present joint experimental and theoretical study, we report thermal rate constants for the O(1D) + H2 reaction within the 50-300 K temperature range. Experimental kinetics measurements were performed using a continuous supersonic flow reactor coupled with pulsed laser photolysis for O(1D) production and pulsed laser induced fluorescence in the vacuum ultraviolet wavelength range (VUV LIF) for O(1D) detection. Theoretical rate constants were obtained using the ring polymer molecular dynamics (RPMD) approach over the two lowest potential energy surfaces 11A and 11A which possess barrierless and thermally activated energy profiles, respectively...

BACKGROUND: Pericardial effusions can cause considerable morbidity and potentially may lead to mortality. Malignant pericardial effusions are uncommon, and data on malignancies encountered in pericardial effusion cytology specimens are limited. METHODS: Relevant records of all pericardial effusions from January 2008 to September 2014 were examined and compared with pericardial biopsy results when performed. Discrepant cases were reviewed to determine the cause of the disagreement...

Do others perceive the personality changes that take place between the ages of 14 and 29 in a similar fashion as the aging person him- or herself? This cross-sectional study analyzed age trajectories in self- versus other-reported Big Five personality traits and in self-other agreement in a sample of more than 10,000 individuals from the myPersonality Project. Results for self-reported personality showed maturation effects (increases in extraversion, conscientiousness, openness to experience, and emotional stability), and this pattern was generally also reflected in other-reports, albeit with discrepancies regarding timing and magnitude...

The discrepancy between the in vitro cytotoxic results and the in vivo performance of Pt56MeSS, prompted us to look into its interactions and those of its Pt(IV) derivatives with human serum, HSA, lipoproteins and serum supplemented cell culture medium. The Pt(II) complex, Pt56MeSS, binds non-covalently and reversibly to slow tumbling proteins in human serum and in cell culture medium and interacts through the phenanthroline with HSA with a Kd of about 1.5 × 10-6. All Pt(IV) complexes were stable to reduction in HS but those with axial carboxylate ligands, cct-[Pt(1S,2S-DACH)(5,6-dimethyl-1,10-phenantroline)(acetato)2](TFA)2 (Pt56MeSS(OAc)2) and cct-[Pt(1S,2S-DACH)(5,6-dimehtyl-1,10-phenantroline)(phenylbutyrate)2](TFA)2 (Pt56MeSS(PhB)2), were spontaneously reduced at pH=7 or higher in phosphate buffer, but not in tris buffer (pH=8)...

Ferroelectrics based on proton tautomerism are promising in low-field and above-room-temperature operations. Here seven organic ferroelectric crystals are examined to search for efficient switching of strong spontaneous polarization on proton tautomerism. Solution-grown crystals exhibit strong pinning of ferroelectric domain walls, but excellent switching performance is awakened by depinning domain walls under thermal annealing and/or repetitive bipolar pulses with a high voltage. Compared with ferroelectric polymers such as polyvinylidefluoride, the optimized polarizations are comparable or stronger in magnitude whereas the coercive fields are two orders of magnitude weaker...

A large discrepancy between the Amerindian contribution to the mitochondrial and nuclear genetic components of 55 Puerto Rican (PR) genomes from the 1000 Genomes Project is identified, with Amerindian mitochondrial haplotypes being highly represented (67.3%), in strong contrast to the Amerindian autosomal contribution (12.9%). I examine the potential causes behind this strong mitonuclear discordance. The Amerindian contribution to the X chromosome is 19.8%, implying assortative mating with Amerindian females during the establishment of the PR population...
