BACKGROUND & AIMS: Several genetic variants have been associated with gastric cancer risk, although these account for only a fraction of gastric cancer cases. We aimed to identify low-frequency and other genetic variants that determine gastric cancer susceptibility. METHODS: We performed exome array analysis of DNA in blood samples from 1113 patients with gastric cancer, collected at hospitals from 2006 to 2010 in China, and 1848 individuals without cancer (controls) undergoing physical examinations...

Wild Helianthus species are a valuable genetic resource for the improvement of cultivated sunflower. We report the discovery and characterization of a unique high frequency production of triploids when cultivated sunflower was pollinated by specific accessions of diploid Helianthus nuttallii T. &. G. and H. maximiliani Schr. Genomic in situ hybridization (GISH) analyses indicated that the triploid F1s had two genomes from the wild pollen sources and one from the cultivated line. Mitotic chromosome analyses indicated that the frequency of triploid progenies from the crosses of cultivated lines × H...

The propagation of acoustic waves through a suspension of spherical particles in a viscous liquid is investigated, through application of a multiple scattering model. The model is based on the multiple scattering formulation of Luppé, Conoir, and Norris [J. Acoust. Soc. Am. 131, 1113-1120 (2012)] which incorporated the effects of thermal and shear wave modes on propagation of the acoustic wave mode. Here, the model is simplified for the case of solid particles in a liquid, in which shear waves make a significant contribution to the effective properties...

Smoking is endemic in drug abuse treatment populations, and smoking prevalence in this population appears unresponsive to existing tobacco control strategies. Clinical and policy guidelines encourage programs to address smoking among clients, and research has identified key barriers to doing so. This report explores the practice of staff and clients smoking together in drug treatment programs, and how this practice is associated with other tobacco-related measures. Clients (N=1113) were surveyed and program directors were interviewed in a national sample of 24 drug abuse treatment programs affiliated with the NIDA Clinical Trials Network...

BACKGROUND: Despite the World Health Organization (WHO) regularly updating guidelines to recommend earlier initiation of antiretroviral therapy (ART) in children, timely enrollment into care and initiation of ART in sub-Saharan Africa in children lags behind that of adults. The impact of implementing increasingly less restrictive ART guidelines on ART initiation in Central Africa has not been described. MATERIALS AND METHODS: Data are from the Central Africa International Epidemiologic Databases to Evaluate AIDS (IeDEA) pediatric cohort of 3,426 children (0-15 years) entering HIV care at 15 sites in Burundi, DRC, and Rwanda...

BACKGROUND: Nonopioid analgesic drugs may interfere with platelet inhibition by aspirin. Recent in vitro and clinical studies in patients with cardiovascular disease have suggested that this pharmacodynamic interaction may also occur with dipyrone, a nonopioid analgesic popular in Europe, Asia and South America. OBJECTIVE: Dipyrone is used extensively in acute and chronic pain. This study was undertaken to provide clinical data, so far missing, on its interactions in this group of patients...

INTRODUCTION: Because of the unclear prognostic effects of ablation of atrial fibrillation (AF), oral anticoagulation (OAC) is often continued after ablation even in asymptomatic patients. We sought to determine the frequency of stroke and AF recurrence in patients on and off therapeutic OAC 1 year after a successful AF ablation. METHODS AND RESULTS: Patients that underwent AF ablation and were free of AF 12 months after ablation were selected from our AF database...

Global trade of agricultural commodities (e.g., animal feed) requires monitoring for fungal toxins. Also, little is known about masked and emerging toxins and metabolites. 1926 samples from 52 countries were analysed for toxins and metabolites. Of 162 compounds detected, up to 68 metabolites were found in a single sample. A subset of 1113 finished feed, maize and maize silage samples containing 57 compounds from 2012 to 2015 from 44 countries was investigated using liquid chromatography and mass spectrometry...

BACKGROUND: Triple-negative breast cancer (TNBC) has a high risk of relapse and there are few chemotherapy options. Although 5-hydroxytryptamine (5-HT, serotonin) signaling pathways have been suggested as potential targets for anti-cancer drug development, the mechanism responsible for the action of 5-HT in TNBC remains unknown. METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting were used to measure mRNA and protein levels, respectively...

Burrowing, an ethologically relevant rodent behaviour, has been proposed as a novel outcome measure to assess the global impact of pain in rats. In a prospective multicentre study using male rats (Wistar, Sprague-Dawley), replication of suppressed burrowing behaviour in the complete Freund adjuvant (CFA)-induced model of inflammatory pain (unilateral, 1 mg/mL in 100 µL) was evaluated in 11 studies across 8 centres. Following a standard protocol, data from participating centres were collected centrally and analysed with a restricted maximum likelihood-based mixed model for repeated measures...

BACKGROUND: Rats (Rattus norvegicus) are increasingly kept as pets, thus more and more requiring veterinary care. Important differences exist between pet and laboratory rats, but little information is available on pet rats. Diagnosis and treatment of pet rat diseases would benefit from RIs specific for this animal population. OBJECTIVES: The aim was to establish RIs for biochemical blood variables, PCV, and body temperature in pet rats. Additionally, influences of sex and feed rationing method (ad libitum, restricted) on these variables were determined...

PROP1 is a pituitary specific transcription factor that plays a crucial role in pituitary organogenesis. The Prop1 shows varied expression patterns that promptly emerge and then fade during the early embryonic period. However, the regulatory mechanisms governing Prop1 expression remain unclear. Here, we investigated whether Prop1 was under epigenetic regulation by DNA methylation. Bisulfite sequencing was performed on DNA obtained from the pituitary glands and livers of rats on embryonic days (E) 13.5 and E14...

BACKGROUND: The Victorian Audit of Surgical Mortality (VASM) seeks to peer-review all deaths associated with surgical care. This study aimed to examine the mortalities that were determined by the assessor to be potentially preventable, and identify the clinical factors associated with these cases. The assessment of preventability of death and its relationship to management issues at different stages of the admission episode, as opposed to whether the management issue(s) alone were preventable have not been reported previously...

BACKGROUND: We examined the relationship between dog walking and physical activity within and between four US cities and Australia and investigated if dog walking is associated with higher perceived safety in US and Australian cities. METHODS: Dog owners (n = 1113) in the Pet Connections Study completed a cross-sectional survey. Data were collected across four study sites; three in the US (San Diego, Nashville, Portland) and a fourth in Australia (Perth). Physical activity, local walking, dog walking, and individual and community perceptions of safety were analysed for dog walkers and non-dog walkers for each study site...
