BACKGROUND: Senior surgical residents are of paramount importance in directing further therapeutic modalities based on their interpretation of critical diagnostic imaging. We propose that senior surgical residents are proficient with interpreting radiologic imaging studies in the trauma patient. METHODS: A prospective cohort study was performed comparing surgery resident interpretations of computerized tomography (CT) scans of the head, maxillofacial bones, spine (cervical, thoracic, lumbar), chest, abdomen, pelvis, and chest X-rays versus final radiologists' reports at a level II trauma center from September 2014 to May 2015...

BACKGROUND: The rapid advancement of sequencing technologies has made it possible to regularly produce millions of high-quality reads from the DNA samples in the sequencing laboratories. To this end, the de Bruijn graph is a popular data structure in the genome assembly literature for efficient representation and processing of data. Due to the number of nodes in a de Bruijn graph, the main barrier here is the memory and runtime. Therefore, this area has received significant attention in contemporary literature...

Quantitative analysis of metabolism has been used to identify driver reactions occurring during cancer development and bottleneck reactions in the metabolic engineering of microorganisms. In this review, we compare the advantages and disadvantages of various metabolic analysis methods. We emphasize that metabolic flux analysis based on material balance is a critical method for quantitative investigations into cell metabolism. The absolute determination of metabolite concentration appears to be essential for evaluating the thermodynamic state of metabolism...

Fish like higher animals, have a well-defined mechanism to produce sex steroids that play a critical role in gonadal development and maturation. In this study, we aimed to analyse the expression pattern of 3β-HSD in different tissues, during ontogenetic development and gonadal recrudescence of Clarias batrachus. A full-length cDNA of 1617 bp including an open reading frame (ORF) of 1125 bp encoding 374 amino acids was isolated from testes of C. batrachus. The docking analysis between C. batrachus 3β-HSD protein and eurycomanone exhibited high binding affinity toward each other with total energy of -108...

Functional coupling of calcium- and alkaline responsive signalling occurs in multiple fungi to afford efficient cation homeostasis. Host microenvironments exert alkaline stress and potentially toxic concentrations of Ca(2+) , such that highly conserved regulators of both calcium- (Crz) and pH- (PacC/Rim) responsive signalling are crucial for fungal pathogenicity. Drugs targeting calcineurin are potent antifungal agents but also perturb human immunity thereby negating their use as anti-infectives, abrogation of alkaline signalling has therefore been postulated as an adjunctive antifungal strategy...

We show how faceted search using a combination of traditional classification systems and mixed-membership topic models can go beyond keyword search to inform resource discovery, hypothesis formulation, and argument extraction for interdisciplinary research. Our test domain is the history and philosophy of scientific work on animal mind and cognition. The methods can be generalized to other research areas and ultimately support a system for semi-automatic identification of argument structures. We provide a case study for the application of the methods to the problem of identifying and extracting arguments about anthropomorphism during a critical period in the development of comparative psychology...

The coral-Symbiodinium association is a critical component of coral reefs as it is the main primary producer and builds the reef's 3-dimensional structure. A breakdown of this endosymbiosis causes a loss of the dinoflagellate photosymbiont, Symbiodinium, and/or its photosynthetic pigments from the coral tissues (i.e., coral bleaching), and can lead to coral mortality. Coral bleaching has mostly been attributed to environmental stressors, and in some cases to bacterial infection. Viral lysis of Symbiodinium has been proposed as another possible cause of some instances of coral bleaching, but this hypothesis has not yet been experimentally confirmed...

Scavenger receptors (SRs) are important pattern recognition receptors (PRRs), which play significant roles in host defense against pathogens by identifying pathogen-associated molecular patterns (PAMPs). In this study, we report the cloning and characterization of a SR from Eriocheir sinensis (EsSR-B1) which is a 500 amino acid protein encoded by a gene comprised of 2726 nucleotides with a 1503 bp open reading frame. The domains of EsSR-B1 were found to be evolutionarily conserved. EsSR-B1 was widely detected in different tissues of E...

REVIEW
Renate Brosch
Visualization is defined as the production of mental images in the process of reading (Esrock 2005: 633). This article is concerned with varieties of visualization during an absorbing reading of a fictional narrative, the mental images that range from an indistinct and largely automatic default visualization to the much more vivid images that occur at significant stages in the narrative. Neuroscientific studies of vision have collected a large and impressively varied body of experimental evidence for two major processing streams - the dorsal and the ventral-specialized for vision-for-action and vision for-perception respectively...

Extracorporeal respiratory support, also known as extracorporeal gas exchange, may be used to rescue the most severe forms of acute hypoxemic respiratory failure with high blood flow venovenous extracorporeal membrane oxygenation. Alternatively, lower flow extracorporeal carbon dioxide removal might be applied to reduce the intensity of mechanical ventilation in patients with less severe forms of the disease. However, critical reading of the results of the randomized trials and case series published to date reveals major methodological biases...

BACKGROUND: Malaria accounts for ~21% of outpatient visits annually in Kenya; prompt and accurate malaria diagnosis is critical to ensure proper treatment. In 2013, formal malaria microscopy refresher training for microscopists and a pilot quality-assurance (QA) programme for malaria diagnostics were independently implemented to improve malaria microscopy diagnosis in malaria low-transmission areas of Kenya. A study was conducted to identify factors associated with malaria microscopy performance in the same areas...

RNA sequencing (RNA-seq) is a high-throughput technology that provides unique insights into the transcriptome. It has a wide variety of applications in quantifying genes/isoforms and in detecting non-coding RNA, alternative splicing, and splice junctions. It is extremely important to comprehend the entire transcriptome for a thorough understanding of the cellular system. Several RNA-seq analysis pipelines have been proposed to date. However, no single analysis pipeline can capture dynamics of the entire transcriptome...

A 77-year-old woman with exudative macular degeneration underwent bilateral intravitreal injections of "stem cells" at a clinic in Georgia. One month and 3 months after injection, she developed retinal detachments in the left and right eyes, respectively. Increased awareness within the medical community of such poor outcomes is critical so that clinics offering untested practices that have been shown to be potentially harmful to patients can be identified and brought under U.S. Food and Drug Administration oversight...

The co-occurrence of reading comprehension difficulties for first language (L1) Chinese and second language (L2) English and associated longitudinal cognitive-linguistic correlates in each language were investigated. Sixteen poor comprehenders in English and 16 poor comprehenders in Chinese, 18 poor readers in both, and 18 children with normal performance in both were identified at age 10. The prevalence rate for being poor in both was 52.94%, suggesting that approximately half of children who are at risk for Chinese reading comprehension difficulty are also at risk for English reading comprehension difficulty...

Biologic therapy is still limited in lupus, where chronic steroid exposure and wide-spectrum immunosuppression are major triggers of organ damage. In this viewpoint, the authors summarize their views for a "half-full or half-empty" glass on targeted therapy in SLE. The are several reasons for seeing the glass half-empty and in this section the authors propose a critical reflection on scarceness of novel targeted lupus therapies. They show how hard it is to identify suitable biological and clinical targets and to choose the patients that may best fit those targets, as well as to stratify patients according to disease subtype and response, all contributing to the final outcome...

Liver myofibroblasts are specialized effector cells that drive hepatic fibrosis, a hallmark process of chronic liver diseases, leading to progressive scar formation and organ failure. Liver myofibroblasts are increasingly recognized as heterogeneous with regards to their origin, phenotype, and functions. For instance, liver myofibroblasts express cell markers that are universally represented such as, ItgαV and Pdgfrβ, or restricted to a given subpopulation such as, Lrat exclusively expressed in hepatic stellate cells, and Gpm6a in mesothelial cells...
