Currently, research on structural health monitoring systems is focused on direct integration of the system into a component or structure. The latter results in a so-called smart structure. One example of a smart structure is a component with integrated strain sensing for continuous load monitoring. Additive manufacturing, or 3D printing, now also enables such integration of functions inside components. As a proof-of-concept, the Fused Deposition Modeling (FDM) technique was used to integrate a strain sensing element inside polymer (ABS) tensile test samples...

Ming-I Brandon Lin, Yu-Ping Huang
Previous studies have shown that using a cell phone to talk or text while walking changes gait kinematics and encourages risky street-crossing behaviors. However, less is known about how the motor-cognitive interference imposed by smartphone tasks affects pedestrians' situational awareness to environmental targets relevant to pedestrian safety. This study systematically investigated the influence of smartphone use on detection of and responses to a variety of roadside events in a semi-virtual walking environment...

BACKGROUND: Spinal cord injury (SCI) results in fatal damage and currently has no effective treatment. The pathological mechanisms of SCI remain unclear. In this study, genome-wide transcriptional profiling of spinal cord samples from injured rats at different time points after SCI was performed by RNA-Sequencing (RNA-Seq). The transcriptomes were systematically characterized to identify the critical genes and pathways that are involved in SCI pathology. RESULTS: RNA-Seq results were obtained from total RNA harvested from the spinal cords of sham control rats and rats in the acute, subacute, and chronic phases of SCI (1 day, 6 days and 28 days after injury, respectively; n = 3 in every group)...

The Japanese flounder (Paralichthys olivaceus) is one of the most important commercial and biological marine fishes. However, the molecular biology involved during embryogenesis and early development of the Japanese flounder remains largely unknown due to a lack of genomic resources. A comprehensive and integrated transcriptome is necessary to study the molecular mechanisms of early development and to allow for the detailed characterization of gene expression patterns during embryogenesis; this approach is critical to understanding the processes that occur prior to mesectoderm formation during early embryonic development...

BACKGROUND: Selaginella moellendorffii, a lycophyte, is a model plant to study the early evolution and development of vascular plants. As the first and only sequenced lycophyte to date, the genome of S. moellendorffii revealed many conserved genes and pathways, as well as specialized genes different from flowering plants. Despite the progress made, little is known about long noncoding RNAs (lncRNA) and the alternative splicing (AS) of coding genes in S. moellendorffii. Its coding gene models have not been fully validated with transcriptome data...

Yang Liu, Yousry A El-Kassaby
We employed an Illumina sequencing approach to identify candidate microRNA cohorts that may greatly contribute to seed dormancy modulation and to construct a microRNA-gene regulatory network in hormone signalling cascades. MicroRNAs (miRNAs) are important signalling molecules and regulate many developmental programs of plants. Some miRNAs have been integrated into gene regulatory networks (GRNs) and coordinate developmental plasticity, but few study systematically investigated how phenotypical variations are regulated through differential expression of miRNA tags in GRNs during seed set...

The degree and dynamics of translational control during mammalian development remain poorly understood. Here we monitored translation of the mammalian genome as cells become specified and organize into tissues in vivo. This identified unexpected and pervasive translational regulation of most of the core signalling circuitry including Shh, Wnt, Hippo, PI3K and MAPK pathways. We further identify and functionally characterize a complex landscape of upstream open reading frames (uORFs) across 5'-untranslated regions (UTRs) of key signalling components...

Translation of poly(A) tails leads to mRNA cleavage but the mechanism and global pervasiveness of this "nonstop/no-go" decay process is not understood. Here we performed ribosome profiling (in a yeast strain lacking exosome function) of short 15-18 nt mRNA footprints to identify ribosomes stalled at 3' ends of mRNA decay intermediates. In this background, we found mRNA cleavage extending hundreds of nucleotides upstream of ribosome stalling in poly(A) and predominantly in one reading frame. These observations suggest that decay-triggering endonucleolytic cleavage is closely associated with the ribosome...

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is one of the leading causes of sudden cardiac death in athletes. However, pre-participation ECG screening has often been criticized for failing to meet cost-effectiveness thresholds, in part because of high false-positive rates and the cost of ECG screening itself. OBJECTIVES: To assess the testing characteristics of an automated ECG algorithm designed to screen for HCM in a multi-institutional pediatric cohort. METHODS: ECGs from patients with HCM aged 12 - 20 years from 3 pediatric institutions were screened for ECG criteria for HCM using a previously described automated computer algorithm developed specifically for HCM ECG screening...

BACKGROUND: The first few years of life are critical for the healthy growth and development of every child. Enrolling children with disabilities or at risk of developmental delay into early intervention services is essential to successfully meet their physical, cognitive, communication, socio-emotional and adaptive needs. However, many children throughout in the United States who are eligible for public services, including early intervention services, are not accessing them. Research has yet to fully describe low enrollment rates and variability in enrollment into early intervention services...

Decompressive hemicraniectomy (DH) plus duroplasty was demonstrated to be effective for treating critically elevated intracranial pressure (ICP). In order to shorten operation time and to avoid the use of autologous or heterologous material, durotomy has been introduced as an alternative to duroplasty. Only limited data is available on the effect of DH and durotomy on the increased ICP in traumatic brain injury (TBI). Therefore, we collected consecutive intraoperative ICP readings during the different steps of DH and durotomy in TBI patients...

Schumpeter's theory of democracy can be read through the lens of the cognitive approach to rationality. Schumpeter himself constructed his theory on the basis of his (neglected) conception of conscious rationality, which considers the process of thinking as composed of conscious/deliberate and unconscious/automatic components. The prevalence of the deliberate over the automatic component can occur in different degrees; as a consequence, individuals exhibit different levels of conscious rationality. Schumpeter makes clear that an essential attribute of democracy is its being a system of government capable of working notwithstanding a low degree of conscious rationality among its citizens...

REVIEW
Ye Chen, Jun Zhou
Long noncoding RNAs (lncRNAs) are recently defined as thousands of RNA molecules longer than 200 nucleotides and lacking an appreciable open reading frame in mammals. Although lncRNAs lack protein-coding function, they play critical roles in the regulation of almost all the protein-coding genes in a cell at various stages including chromatin modification, transcription and post-transcriptional processing. It is thus not surprising that lncRNAs may be the crucial regulators in the normal development, physiology and pathology...

Rapid morphological and gene expression changes occur during the early formation of a mammalian blastocyst. Critical to successful retention of the blastocyst and pregnancy is a functional trophectoderm (TE) that supplies the developing embryo with paracrine factors and hormones. The contribution of TE conformational changes to gene expression was examined in equine induced trophoblast (iTr) cells. Equine iTr cells were cultured as monolayers or in suspension to form spheres. The spheres are hollow and structurally reminiscent of native equine blastocysts...

: Some bacteria, when infected by their viral parasites (bacteriophages), undergo a suicidal response that also terminates productive viral replication (abortive infection; Abi). This response can be viewed as an altruistic act protecting the uninfected bacterial clonal population. Abortive infection can occur through the action of Type III protein-RNA toxin-antitoxin (TA) systems, such as ToxINPa from the phytopathogen, Pectobacterium atrosepticum Rare spontaneous mutants evolved in the generalized transducing phage, ΦM1, which escaped ToxINPa-mediated abortive infection in P...

Journal clubs are used in both clinical and academic settings in order for clinicians and students to utilize current best-practices, become competent in evidence based practice and develop critical appraisal skills. Journal clubs encourage students to practice searching for relevant research, critically appraising articles, and contributing to open discussions with peers. Establishing the practice of reading and critiquing literature in the classroom can enable the creation of a habit of using current evidence when students enter practice...

BACKGROUND: Alcohol media literacy programs seek to mitigate the potentially harmful effects of alcohol advertising on children's drinking intentions and behaviours through equipping them with skills to challenge media messages. In order for such programs to be effective, the teaching and learning experiences must be tailored to their specific cultural context. Media in the Spotlight is an alcohol media literacy program aimed at 9 to 12 year old Australian children. This study evaluates the process and implementation of the program, outlining the factors that facilitated and inhibited implementation...

Generally, writing about the medicine in the Ancient Egypt, historians adopt an approach rather benevolent than critical, giving to its practice merits that never had. Reading without prejudice the famous twelve papyri -and now one more- we can't less to pronounce a condemnatory sentence, because at the end this medicine looks like a patchwork of ignorance, superstition, magic believes and a pair of grains of knowledge. However, we can rescue its surgical practice, very useful, sometimes efficient, and quite necessary in those centuries of war, slavery and permanent abuse of the weak and the poor people by the high political rulers and priests...

Staphylococcus aureus TF2758 is a clinical isolate from an atheroma and a super-biofilm-elaborating/polysaccharide intercellular adhesin (PIA)/poly-N-acetylglucosamine (PNAG)-overproducing strain (L. Shrestha et al., Microbiol Immunol 60:148-159, 2016, https://doi.org/10.1111/1348-0421.12359). A microarray analysis and DNA genome sequencing were performed to identify the mechanism underlying biofilm overproduction by TF2758. We found high transcriptional expression levels of a 7-gene cluster (satf2580 to satf2586) and the ica operon in TF2758...

OBJECTIVE: This study explored patient perspectives of how online access to clinical notes (OpenNotes) within the Veterans Affairs (VA) health care system may affect patients' relationships with their mental health clinicians. METHODS: Semistructured qualitative interviews were conducted with 28 patients receiving VA mental health care who had accessed OpenNotes. Transcripts were coded and analyzed with a constant comparative approach. RESULTS: Respondents consistently reported that patient-clinician relationships-feelings of trust in particular-are critical to the therapeutic process and that reading clinical notes strengthens or strains patients' trust in mental health clinicians...
