A Technical Performance Study and Proposed Systematic and Comprehensive Evaluation of an ML-based CDS Solution for Pediatric Asthma.

Achieving optimal care for pediatric asthma patients depends on giving clinicians efficient access to pertinent patient information. Unfortunately, adherence to guidelines or best practices has shown to be challenging, as relevant information is often scattered throughout the patient record in both structured data and unstructured clinical notes. Furthermore, in the absence of supporting tools, the onus of consolidating this information generally falls upon the clinician.

Participation of rural patients in clinical trials at a multisite academic medical center.

Objective: Clinical trials, which are mainly conducted in urban medical centers, may be less accessible to rural residents. Our aims were to assess participation and the factors associated with participation of rural residents in clinical trials.

Methods: Using geocoding, the residential address of participants enrolled into clinical trials at Mayo Clinic locations in Arizona, Florida, and the Midwest between January 1, 2016, and December 31, 2017, was categorized as urban or rural.

Expert artificial intelligence-based natural language processing characterises childhood asthma.

Introduction: The lack of effective, consistent, reproducible and efficient asthma ascertainment methods results in inconsistent asthma cohorts and study results for clinical trials or other studies. We aimed to assess whether application of expert artificial intelligence (AI)-based natural language processing (NLP) algorithms for two existing asthma criteria to electronic health records of a paediatric population systematically identifies childhood asthma and its subgroups with distinctive characteristics.

Methods: Using the 1997-2007 Olmsted County Birth Cohort, we applied validated NLP algorithms for Predetermined Asthma Criteria (NLP-PAC) as well as Asthma Predictive Index (NLP-API).

Public feedback on a proposed statewide virtual translational research community.

Introduction: Researchers have explored using the internet and social media to recruit participants to specific research projects. Less systematic work has been done to inform the engagement of large populations in virtual communities to advance clinical and translational science. We report on our first step to use social media to engage Minnesota residents by studying the willingness of participants to engage in a virtual (Facebook) community about the concepts of health and health-related research.

Increasing Incidence and Altered Presentation in a Population-based Study of Pediatric Celiac Disease in North America.

Objectives: Celiac disease (CD) is a common immune-mediated disorder that affects up to 1% of the general population. Recent reports suggest that the incidence of CD has reached a plateau in many countries. We aim to study the incidence and altered presentation of childhood CD in a well-defined population.

Amyloid-beta-activated human microglial cells through ER-resident proteins.

Microglial activation in the central nervous system is a key event in the neuroinflammation that accompanies neurodegenerative diseases such as Alzheimer's disease (AD). Among cytokines involved in microglial activation, amyloid β (Aβ) peptide is known to be a key molecule in the induction of diverse inflammatory products, which may lead to chronic inflammation in AD. However, proteomic studies of microglia in AD are limited due to lack of proper cell or animal model systems.

The role of cyanopterin in UV/blue light signal transduction of cyanobacterium Synechocystis sp. PCC 6803 phototaxis.

We analyzed the effects of inactivating the pteridine glycosyltransferase gene (pgtA) on the photomovement of the cyanobacterium Synechocystis sp. PCC 6803 under different light conditions. The pgtA mutant displayed abnormal photomovement under UV-A/blue light.

NbHB1, Nicotiana benthamiana homeobox 1, is a jasmonic acid-dependent positive regulator of pathogen-induced plant cell death.

Induction of cell death is an important component of plant defense against pathogens. There have been many reports on the role of phytohormones in pathogen-induced cell death, but jasmonic acid (JA) has not been implicated as a regulator of the response. Here, we report the function of NbHB1, Nicotiana benthamiana homeobox1, in pathogen-induced cell death in connection with JA signaling.

Histone occupancy-dependent and -independent removal of H3K27 trimethylation at cold-responsive genes in Arabidopsis.

Trimethylation of histone H3 at lysine 27 (H3K27me3) is a histone marker that is present in inactive gene loci in both plants and animals. Transcription of some of the genes with H3K27me3 should be induced by internal or external cues, yet the dynamic fate of H3K27me3 in these genes during transcriptional regulation is poorly understood in plants. Here we show that H3K27me3 in two cold-responsive genes, COR15A and ATGOLS3, decreases gradually in Arabidopsis during exposure to cold temperatures.

Arabidopsis ING and Alfin1-like protein families localize to the nucleus and bind to H3K4me3/2 via plant homeodomain fingers.

In yeast and animals, tri- and dimethylation of histone H3 at lysine 4 (H3K4me3/2) are markers of transcriptionally active genes that have recently been shown to be primary ligands for the plant homeodomain (PHD) finger. However, PHD fingers able to bind to H3K4me3/2 have not been identified in plants. Here, we identify 83 canonical PHD fingers in the Arabidopsis proteome database that are supported by both SMART and Pfam prediction.

A 125 kDa RNase E/G-like protein is present in plastids and is essential for chloroplast development and autotrophic growth in Arabidopsis.

Endoribonuclease E (RNase E) is a regulator of global gene expression in Escherichia coli and is the best studied member of the RNase E/G ribonuclease family. Homologues are present in other bacteria but the roles of plant RNase E/G-like proteins are not known. Arabidopsis thaliana contains a single nuclear gene (At2g04270) encoding a product with the conserved catalytic domain of RNase E/G-like proteins.

Stress-induced expression of choline oxidase in potato plant chloroplasts confers enhanced tolerance to oxidative, salt, and drought stresses.

Transgenic potato plants (Solanum tuberosum L. cv. Superior) with the ability to synthesize glycinebetaine (GB) in chloroplasts (referred to as SC plants) were developed via the introduction of the bacterial choline oxidase (codA) gene under the control of an oxidative stress-inducible SWPA2 promoter.

LONGIFOLIA1 and LONGIFOLIA2, two homologous genes, regulate longitudinal cell elongation in Arabidopsis.

Plants have diversified their leaf morphologies to adapt to diverse ecological niches. The molecular components responsible for regulating leaf morphology, however, have not been fully elucidated. By screening Arabidopsis activation-tagging lines, we identified a dominant mutant, which we designated longifolia1-1D (lng1-1D).

Light activates the degradation of PIL5 protein to promote seed germination through gibberellin in Arabidopsis.

Angiosperm seeds integrate various environmental signals, such as water availability and light conditions, to make a proper decision to germinate. Once the optimal conditions are sensed, gibberellin (GA) is synthesized, triggering germination. Among environmental signals, light conditions are perceived by phytochromes.

Co-transformation using a negative selectable marker gene for the production of selectable marker gene-free transgenic plants.

A negative selectable marker gene, codA, was successfully co-transformed with a GUS reporter gene to develop selectable marker gene-free transgenic plants. The pNC binary vector contained a T-DNA harboring the codA gene next to the nptII gene, while a second binary vector, pHG, contained a GUS reporter gene. Tobacco plants ( Nicotiana tabacum cv.

Degradation of phytochrome interacting factor 3 in phytochrome-mediated light signaling.

Plant photoreceptors regulate various developmental processes. Among the photoreceptors, phytochromes, red and far-red light receptors, regulate light responses through many signaling components, including phytochrome-interacting proteins. The functional relationships among phytochromes and their interacting proteins, however, have not been clearly established.

Expression of an evolutionarily distinct novel BiP gene during the unfolded protein response in Arabidopsis thaliana.

Compared to mammals, little is known about the unfolded protein response (UPR) in plants. Using an oligonucleotide array comprising approximately 8200 Arabidopsis genes we investigated the effect of endoplasmic reticulum (ER) stress on gene expression. Expression of 26 genes increased, including at least nine whose products act in the ER, while their transcriptional activations were confirmed by promoter analyses.

Conservation between animals and plants of the cis-acting element involved in the unfolded protein response.

Using Arabidopsis thaliana, we identified the cis-element involved in the plant unfolded protein response (UPR). In transgenic plants, tunicamycin stimulated expression of a reporter gene under the control of the BiP promoter and promoter analysis identified a 24 bp sequence crucial to this induction. When fused with a minimal promoter, a hexamer of this sequence was sufficient for induction of a reporter gene in protoplasts treated with tunicamycin or dithiothreitol.

Characterization of an abscisic acid responsive gene homologue from Cucumis melo.

A cDNA and genomic DNA encoding an abscisic acid responsive gene (ASR) homologue (Asr1) was isolated from an inodorus melon, Cucumis melo var. kuwata, cDNA and genomic library. The Asr1 gene showed the strongest fruit-specific expression and differential expression profiles during fruit development, which were expressed from a low copy gene.

Diversity and varietal classification of Hibiscus syriacus L. with the heterogeneity within retrotransposon-like elements.

Retrotransposons are present in multi-copy numbers that are integrated into plant genomes with considerable heterogeneous sequences within a single plant and between plant species, which allows the use of retrotransposons as additional sources of DNA polymorphism. A primer design for the sequence-tagged specific site and cleaved amplified polymorphic sequences (STS-CAPs) that are derived from retrotransposon-like sequences was developed for the molecular marker analysis in Hibiscus syriacus. This method was applied for the detection of sequence variations of intact retrotransposons that exist in plant genomes, which resulted in higher polymorphisms than in the amplified fragment length polymorphism (AFLP).

Genomic cloning and characterization of glutathione reductase gene from Brassica campestris var. Pekinensis.

We have isolated and characterized a gene encoding cytosolic glutathione reductase from Brassica campestris (B. campestris). The gene (BcgGR1) is presented as a single copy in the B.

Characterization of two homologs of Ire1p, a kinase/endoribonuclease in yeast, in Arabidopsis thaliana.

The accumulation of unfolded proteins in the endoplasmic reticulum (ER) elicits an ER-to-nucleus signaling pathway known as the unfolded protein response (UPR) in eukaryotes. In yeast, Ire1p, a kinase/endoribonuclease in the ER membrane, plays a key role in the UPR signaling. We isolated two cDNA homologs of IRE1 gene from Arabidopsis (AtIre1a, AtIre1b).

Functional MR imaging of working memory in the human brain.

Objective: In order to investigate the functional brain anatomy associated with verbal and visual working memory, functional magnetic resonance imaging was performed.

Materials And Methods: In ten normal right handed subjects, functional MR images were obtained using a 1.5-T MR scanner and the EPI BOLD technique.

Sequence variability of nine cytosolic ascorbate peroxidases in polyploid strawberry.

Little is known about differential gene expression at the molecular level in polyploid plants. Here, we describe the molecular analysis of ApxSC (cytosolic ascorbate peroxidase from a polyploid strawberry) genes. Fifty-three cDNAs encoding ApxSC were isolated from a strawberry fruit cDNA library.

Characterization of trichobakin, a type I ribosome-inactivating protein from Trichosanthes sp. Bac Kan 8-98.

We have isolated a genomic clone encoding trichobakin (TBK), a type I ribosome-inactivating protein from the plant Trichosanthes sp. Bac Kan 8-98 (family Cucurbitaceae), by PCR using specific primers designed from the cDNA sequences of alpha-trichosanthin. The sequence encoding mature TBK was constructed in the pET-21d(+) vector for overexpression in Escherichia coli strain BL21(DE3).
