In this paper, we present a robust text detection approach in natural images which is based on region proposal mechanism. A powerful low-level detector named saliency enhanced-MSER extended from the widely-used MSER is proposed by incorporating saliency detection methods, which ensures a high recall rate. Given a natural image, character candidates are extracted from three channels in a perception-based illumination invariant color space by saliency-enhanced MSER algorithm. A discriminative convolutional neural network (CNN) is jointly trained with multi-level information including pixel-level and character-level information as character candidate classifier...

Stress cardiomyopathy or Tako Tsubo cardiomyopathy is a cardiac pathology evoking acute coronary syndrome characterized by electrocardiographic signs, cardiac enzyme elevation and no obstructive coronary lesions. It generally affects postmenopausal women and it usually occurs after periods of intense stress. Disease onset is widely variable, ranging from anginal pain (most common) to cardiogenic shock. Exact pathophysiological mechanism continues to be debated. Various hypotheses have been posited. Abrupt elevation of adrenaline levels appears to be the most credible...

Various studies report substantial increases in intrinsic water-use efficiency (W i ), estimated using carbon isotopes in tree rings, suggesting trees are gaining increasingly more carbon per unit water lost due to increases in atmospheric CO2. Usually, reconstructions do not, however, correct for the effect of intrinsic developmental changes in W i as trees grow larger. Here we show, by comparing W i across varying tree sizes at one CO2 level, that ignoring such developmental effects can severely affect inferences of trees' W i ...

BACKGROUND: The risk of postoperative complications increases with undiagnosed obstructive sleep apnea (OSA). The high-risk OSA (HR-OSA) patients can be easily identified using the STOP-Bang screening tool. The aim of this systematic review and meta-analysis is to determine the association of postoperative complications in patients screened as HR-OSA versus low-risk OSA (LR-OSA). METHODS: The following data bases were searched from January 1, 2008, to October 31, 2016, to identify the eligible articles: Cochrane Central Register of Controlled Trials, MEDLINE, PubMed, Cochrane Databases of Systematic Reviews, Medline-in-Process & other nonindexed citations, Google Scholar, Embase, Web of Sciences and Scopus...

The objective of this network meta-analysis was to identify and rank different ridge preservation procedures using allograft, xenograft, or extraction only by dimensional changes in ridge width and height after tooth extraction. Electronic and hand searches of several databases were performed in September 2016 to identify randomized controlled trials on extraction and ridge preservation with 3 to 7 months of follow-up. Eight studies were included in the network meta-analysis. The total number of teeth included in these trials was 466, which were randomly assigned to treatment groups...

Pubertal growth in body size and functional capacities were examined in adolescent soccer players (n = 33). The average age at baseline was 10.9 (9.8-11.8 years). Peak height velocity (PHV) and growth curves for body mass and functional performance (countermovement jump, 15-m sprint, agility and Yo-Yo intermittent recovery test - level 1) were determined with Bayesian multilevel models. Estimates for PHV and age at PHV were 8.1 cm/year (95% credible interval: 4.2-18.5 cm/year) and 12.9 years (95% credible interval: 11...

Reshma Mohamed Ansari, Norfaizatul Shalida Omar
Dietary health supplements for weight loss seem to be the future nowadays. However, this industry is plagued by lack of regulations and ignorance regarding the constituents of the supplements. Of all the supplements consumed, the ones for weight loss are most commonly found in the market. Reports of liver failure, kidney impairment and worsening of chronic ailments in patients who consume these supplements are surfacing recently which make us question the credibility of these products. The safety of these products lie in the clear stating of the ingredients by the manufacturer, well informed patient, knowledgeable physician and tight regulations from the regulatory board...

Robert A Nash
Doctored photographs can shape what people believe and remember about prominent public events, perhaps due to their apparent credibility. In three studies, subjects completed surveys about the 2012 London Olympic torch relay (Experiment 1) or the 2011 Royal Wedding of Prince William and Kate Middleton (Experiments 2-3). Some were shown a genuine photo of the event; others saw a doctored photo that depicted protesters and unrest. A third group of subjects saw a doctored photo whose inauthenticity had been made explicit, either by adding a written disclaimer (Experiment 1) or by making the digital manipulation deliberately poor (Experiments 2-3)...

The field of sport psychology is dynamic and growing. To continue building credibility with the public and allied professionals, effective and ethical practice is crucial. Advances in technology have allowed sport psychology professionals to consult with athletes from a distance, but practitioners must be mindful of their competency to use technology, confidentiality concerns, and the suitability of technology for their clients. Movement toward defining competency and clarifying issues of title usage are additional areas in which the field is gaining momentum...

E Andres Houseman, M Abbas Virji
Objective: Direct reading instruments are valuable tools for measuring exposure as they provide real-time measurements for rapid decision making. However, their use is limited to general survey applications in part due to issues related to their performance. Moreover, statistical analysis of real-time data is complicated by autocorrelation among successive measurements, non-stationary time series, and the presence of left-censoring due to limit-of-detection (LOD). A Bayesian framework is proposed that accounts for non-stationary autocorrelation and LOD issues in exposure time-series data in order to model workplace factors that affect exposure and estimate summary statistics for tasks or other covariates of interest...

BACKGROUND: DNA methylation is an important epigenetic modification. It can regulate the expression of many key genes without changing the primary structure of the genomic DNA, and plays a vital role in the growth and development of the organism. The genome-wide DNA methylation profile of the cytoplasmic male sterile (CMS) line in soybean has not been reported so far. RESULTS: In this study, genome-wide comparative analysis of DNA methylation between soybean CMS line NJCMS5A and its maintainer NJCMS5B was conducted by whole-genome bisulfite sequencing...

For many years after its invention around 1796, homeopathy was widely used in people and later in animals. Over the intervening period (1796-2016) pharmacology emerged as a science from Materia Medica (medicinal materials) to become the mainstay of veterinary therapeutics. There remains today a much smaller, but significant, use of homeopathy by veterinary surgeons. Homeopathic products are sometimes administered when conventional drug therapies have not succeeded, but are also used as alternatives to scientifically based therapies and licensed products...

BACKGROUND: The care needs of women with gynecological cancer are complex and change over the course of their cancer journey. Specialist nurses are well positioned to play a role in meeting the needs of women with gynecological cancer although their role and scope of practice have not been well defined. As patients are a key stakeholder, understanding their experience of care is an important step in better defining the role and scope of practice of specialist nurses in gynecological oncology in Australia and New Zealand...
