A nano-grained layer including line defects was formed on the surface of a Ti alloy (Tialloy, Ti-6Al-4V ELI). Then, the micro- and nano-grained Tialloy with the formation of TiO2 on its top surface was coated with a bioactive Ta layer with or without incorporating an antibacterial agent of Ag that was manufactured by magnetron sputtering. Subsequently, the influence of the charged defects (the defects that can be electrically charged on the surface) on the interfacial bonding strength and hardness of the surface system was studied via an electronic model...

INTRODUCTION: There are no existing data on whether performance on the United States Medical Licensing Examination (USMLE) predicts success in American Board of Emergency Medicine (ABEM) certification. The aim of this study was to determine the presence of any association between USMLE scores and first-time success on the ABEM qualifying and oral certification examinations. METHODS: We retrospectively collected USMLE Step 1, Step 2 Clinical Knowledge (CK) scores and pass/fail results from the first attempt at ABEM qualifying and oral examinations from residents graduating between 2009 and 2011 from nine EM programs...

OBJECTIVE: This study sought to assess the influence of cervical preflaring and reuse after resterilization, on fracture strength and plastic deformation and/or surface cracking in reciprocating nickel-titanium [NiTi] endodontic instruments after root canal instrumentation of extracted human teeth. MATERIALS AND METHODS: Forty engine-driven reciprocating NiTi instruments (20 Reciproc(®) [RC], VDW; 20 WaveOne(®) [WO], Dentsply) were used in root canal instrumentation of extracted human molars...

We published a phylogenetic comparative analysis that found geckos had gained and lost adhesive toepads multiple times over their long evolutionary history (Gamble et al. 2012). This was consistent with decades of morphological studies showing geckos had evolved adhesive toepads on multiple occasions and that the morphology of geckos with ancestrally padless digits can be distinguished from secondarily padless forms. Recently, Harrington and Reeder (2017) reanalyzed data from Gamble et al. (2012) and found little support for the multiple origins hypothesis...

The rapid increase in the production and application of various types of nanomaterials increases the possibility of their presence in total environment, which subsequently raises concerns about their potential threats to the first trophic level of organisms, specifically under varying environmental constraints. In this work, seeds of Cucurbita pepo L. were cultured in MS basal medium exposed to multi-walled carbon nanotubes (MWCNTs) at different concentrations (0, 125, 250, 500 and 1000μgmL(-1)) under two levels of water potential, well-watered (0MPa) and water stress (-1...

BACKGROUND: In the USA, men who have sex men (MSM) are at high risk for HIV, and black MSM have a substantially higher prevalence of infection than white MSM. We created a simulation model to assess the strength of existing hypotheses and data that account for these disparities. METHODS: We built a dynamic, stochastic, agent-based network model of black and white MSM aged 18-39 years in Atlanta, GA, USA, that incorporated race-specific individual and dyadic-level prevention and risk behaviours, network attributes, and care patterns...

Aims: Previous studies have demonstrated substantial variability in manual assessment of QRS complex duration (QRSd). Disagreements in QRSd measurements were also found in several automated algorithms tested on digitized electrocardiogram (ECG) recordings. The aim of our study was to investigate the variability of automated QRSd measurements performed by two commercially available electrocardiographs. Methods and Results: Two GE MAC 5000 (GE-1 and GE-2) electrocardiographs and two Mortara ELI 350 (Mortara-1 and Mortara-2) electrocardiographs were used in the study...

#11
Simon Renny-Byfield, Eli Rodgers-Melnick, Jeffrey Ross-Ibarra
The maize genome experienced an ancient whole genome duplication approximately 10 million years ago and the duplicate subgenomes have since experienced reciprocal gene loss (fractionation) such that many genes have returned to single-copy status. This process has not affected the subgenomes equally; reduced gene expression in one of the subgenomes mitigates the consequences of mutations and gene deletions and is thought to drive higher rates of fractionation. Here we take advantage of published genome-wide SNP and phenotype association data to show that, in accordance with predictions of this model, paralogs with greater expression contribute more to phenotypic variation compared to their lowly expressed counterparts...

Libi Kohavi, Eli Sprecher, Eyal Zur, Ofir Artzi
BACKGROUND: Tranilast (N-[3, 4-dimethoxycinnamoyl] anthranilic acid), an antiallergic drug, has been shown to attenuate scar formation possibly through inhibition of transforming growth factor beta 1 activity and consequent suppression of collagen synthesis in fibroblasts. OBJECTIVE: The authors aimed at evaluating the efficacy and safety of tranilast 8% gel in improving the appearance and symptoms of new postcesarean section surgical wounds. METHODS: In this prospective double-blind split-scar study, the authors treated each half scar of 26 women with either tranilast 8% liposomal gel or tranilast-free liposomal gel (placebo)...

BACKGROUND: Heart failure is a major cause of mortality and morbidity, particularly among patients with advanced disease and no access to cardiac transplantation. LVAD implantation is not only a bridge-to-transplantation option for patients awaiting a heart donor, but is often used as bridge-to-destination therapy in patients unsuited for transplantation for various reasons. LVAD infection is considered the second-most common cause of death in patients who survive the initial 6 months on LVAD support...

OBJECTIVES: Catheter ablation for rhythm control has emerged as a successful therapeutic option for the treatment of atrial fibrillation (AF), though it has not been well studied in octogenarians. This study evaluates its safety in octogenarians in a community hospital and reviews the benefits of rhythm control. METHODS: Among 1,592 patients undergoing AF ablation, 84 octogenarian were identified. The primary outcome was normal sinus rhythm (NSR) on electrocardiogram at discharge...

Genome-wide association studies have identified over 150 loci associated with lipid traits, however, no large-scale studies exist for Hispanics and other minority populations. Additionally, the genetic architecture of lipid-influencing loci remains largely unknown. We performed one of the most racially/ethnically diverse fine-mapping genetic studies of HDL-C, LDL-C, and triglycerides to-date using SNPs on the MetaboChip array on 54,119 individuals: 21,304 African Americans, 19,829 Hispanic Americans, 12,456 Asians, and 530 American Indians...

The present study recorded a case series of 11 patients diagnosed with amniotic sheets at an outpatient obstetric clinic affiliated to Saint Joseph University, Beirut, Lebanon, between January 1, 2003, and December 31, 2013. Of these patients, nine were diagnosed during routine obstetric ultrasonography examination and two patients were referred from other centers. All patients included in the case series had singleton pregnancies and the mean length of pregnancy at diagnosis was 17 weeks (range 13-22). This article is protected by copyright...

Infants born to women with diabetes or obesity are exposed to excess circulating fuels during fetal heart development and are at higher risk of cardiac diseases. We have previously shown that late-gestation diabetes, especially in conjunction with a maternal high-fat (HF) diet, impairs cardiac functions in rat-offspring. This study investigated changes in genome-wide histone modifications in newborn hearts from rat-pups exposed to maternal diabetes and HF-diet. Chromatin-immunoprecipitation-sequencing revealed a differential peak distribution on gene promoters in exposed pups with respect to acetylation of lysines 9 and 14 and to trimethylation of lysines 4 and 27 in histone H3 (all, false discovery rate, FDR < 0...
