A root nodule microbiome sequencing data set from red alder (Alnus rubra Bong.).

There have been frequent reports of more than one strain of the nitrogen-fixing symbiont, Frankia, in the same root nodule of plants in the genus Alnus, but quantitative assessments of their relative contributions have not been made to date. Neither has the diversity of other microbes, having potential functional roles in symbiosis, been systematically evaluated. Alnus rubra root nodule microbiota were studied using Illumina short read sequencing and kmer-based read classification.

Shaping minds and hearts in medical education: Embedding and implementing a personal and professional development curriculum.

This paper explores personal and professional development (PPD) as a key learning domain for the future of medical education and person-centered care. Guided by existing curriculum development models and lessons learned in practice, scenarios from academic and clinical learning environments will guide a theory-driven discussion of concepts and competencies that humanize the practice of medicine, such as emotional intelligence, professional identity formation, lifelong learning and inclusive practice. Factors contributing to contemporary curriculum implementation will be informed by a case study of a PPD program delivered to post-graduate medical students in Australia and propose an action-focused series of next steps to connect past, current and future directions for medical schools and graduates.

Dirigent isoflavene-forming PsPTS2: 3D structure, stereochemical, and kinetic characterization comparison with pterocarpan-forming PsPTS1 homolog in pea.

Pea phytoalexins (-)-maackiain and (+)-pisatin have opposite C6a/C11a configurations, but biosynthetically how this occurs is unknown. Pea dirigent-protein (DP) PsPTS2 generates 7,2'-dihydroxy-4',5'-methylenedioxyisoflav-3-ene (DMDIF), and stereoselectivity toward four possible 7,2'-dihydroxy-4',5'-methylenedioxyisoflavan-4-ol (DMDI) stereoisomers was investigated. Stereoisomer configurations were determined using NMR spectroscopy, electronic circular dichroism, and molecular orbital analyses.

Plant-based red colouration of shell beads 15,000 years ago in Kebara Cave, Mount Carmel (Israel).

Decorating the living space, objects, body and clothes with colour is a widespread human practice. While the habitual use of red mineral pigments (such as iron-oxide, e.g.

Bone aerophones from Eynan-Mallaha (Israel) indicate imitation of raptor calls by the last hunter-gatherers in the Levant.

Direct evidence for Palaeolithic sound-making instruments is relatively rare, with only a few examples recorded from Upper Palaeolithic contexts, particularly in European cultures. However, theoretical considerations suggest that such artefacts have existed elsewhere in the world. Nevertheless, evidence for sound production is tenuous in the prehistoric archaeological record of the Levant, the study of music and its evolution being sparsely explored.

Dirigent protein subfamily function and structure in terrestrial plant phenol metabolism.

Aquatic plant transition to land, and subsequent terrestrial plant species diversification, was accompanied by the emergence and massive elaboration of plant phenol chemo-diversity. Concomitantly, dirigent protein (DP) and dirigent-like protein subfamilies, derived from large multigene families, emerged and became extensively diversified. DP biochemical functions as gateway entry points into new and diverse plant phenol skeletal types then markedly expanded.

Annotated genome sequence of a fast-growing diploid clone of red alder (Alnus rubra Bong.).

Red alder (Alnus rubra Bong.) is an ecologically significant and important fast-growing commercial tree species native to western coastal and riparian regions of North America, having highly desirable wood, pigment, and medicinal properties. We have sequenced the genome of a rapidly growing clone.

Meta-analysis of the space flight and microgravity response of the Arabidopsis plant transcriptome.

Spaceflight presents a multifaceted environment for plants, combining the effects on growth of many stressors and factors including altered gravity, the influence of experiment hardware, and increased radiation exposure. To help understand the plant response to this complex suite of factors this study compared transcriptomic analysis of 15 Arabidopsis thaliana spaceflight experiments deposited in the National Aeronautics and Space Administration's GeneLab data repository. These data were reanalyzed for genes showing significant differential expression in spaceflight versus ground controls using a single common computational pipeline for either the microarray or the RNA-seq datasets.

[Atherosclerosis, an inflammatory disease].

Chronic inflammation is recognized as a contributing factor to the development, progression and complications of atherosclerosis. The inflammatory nature of atherosclerosis has been proven by the presence of inflammatory cells, cytokines and chemokines at all stages of the disease. There is a widely accepted association between cardiovascular events and serum inflammatory markers, such as CRP, IL-6 and IL-1? produced via the inflammasome pathway.

Pain management after third molar extractions in adolescents: a qualitative study.

Background: Understanding how adolescent patients make decisions about pain management after complex dental procedures could help reduce the use of opioid medications and the potential for future opioid misuse in this population. This qualitative study explores how adolescents manage pain, including how decision making with parents and providers affect their experience with opioid and non-opioid analgesics after third molar dental extractions.

Methods: We used a qualitative approach for the analysis of 30 telephone-based semi-structured interviews completed by 15 dyads between May and August 2019, which included 15 adolescents (15-17 years) who underwent a dental extraction, and a parent or guardian for each adolescent.

sequencing and native mass spectrometry revealed hetero-association of dirigent protein homologs and potential interacting proteins in × .

The discovery of dirigent proteins (DPs) and their functions in plant phenol biochemistry was made over two decades ago with × Stereo-selective, DP-guided, monolignol-derived radical coupling was then reported to afford the optically active lignan, (+)-pinoresinol from coniferyl alcohol, provided one-electron oxidase/oxidant capacity was present. It later became evident that DPs have several distinct sub-families, presumably with different functions. Some known DPs require other essential enzymes/proteins ( oxidases) for their functions.

Patient, Provider Type, and Procedure Type Factors Associated with Opioid Prescribing by Dentists in a Health Care System.

Introduction: Reports examining opioid prescribing for dental conditions are limited and do not examine patient-level factors. This study examines the association of patient age, sex, race, ethnicity, Medicaid coverage, and the need for an interpreter in addition to procedure type and dental provider type with receipt of an opioid prescription in dental care settings within a large health system.

Materials And Methods: This study was conducted utilizing data from the electronic health record of HealthPartners, a large dental practice embedded within a health care system.

New Insights Into Lignification via Network and Multi-Omics Analyses of Arogenate Dehydratase Knock-Out Mutants in .

Multiple arogenate dehydratase () knock-out (KO) mutants, with phenotypes having variable lignin levels (up to 70% reduction), were studied to investigate how differential reductions in ADTs perturb its overall plant systems biology. Integrated "omics" analyses (metabolome, transcriptome, and proteome) of wild type (WT), single and multiple KO lines were conducted. Transcriptome and proteome data were collapsed into gene ortholog (GO) data, with this allowing for enzymatic reaction and metabolome cross-comparisons to uncover dominant or likely metabolic biosynthesis reactions affected.

NASA GeneLab RNA-seq consensus pipeline: standardized processing of short-read RNA-seq data.

With the development of transcriptomic technologies, we are able to quantify precise changes in gene expression profiles from astronauts and other organisms exposed to spaceflight. Members of NASA GeneLab and GeneLab-associated analysis working groups (AWGs) have developed a consensus pipeline for analyzing short-read RNA-sequencing data from spaceflight-associated experiments. The pipeline includes quality control, read trimming, mapping, and gene quantification steps, culminating in the detection of differentially expressed genes.

RNA Modulation of Chlorogenic Acid and Lignin Deposition in and Insufficient Compensatory Metabolic Cross-Talk.

Chlorogenic acid (CGA) and guaiacyl/syringyl (G/S) lignin formation involves hydroxycinnamoyl ester intermediacy, the latter formed via hydroxycinnamoyl CoA:shikimate hydroxycinnamoyl transferase (HCT) and hydroxycinnamoyl CoA:quinate hydroxycinnamoyl transferase (HQT) activities. and RNA silencing of a commercial tobacco () K326 line was examined herein. gene silencing gave relatively normal plant phenotypes, with CGA levels reduced (down to 1% of wild type) with no effects on lignin.

The evolution of the CTO-PCI landscape in Belgium and Luxembourg: a four-year appraisal.

Background: To chart the evolution of the CTO-PCI landscape in Belgium and Luxembourg, the Belgian Working Group on Chronic Total Occlusions (BWGCTO) was established in 2016.

Methods: Between May 2016 and December 2019, patients undergoing a CTO-PCI treatment were prospectively and consecutively enrolled. Twenty-one centres in Belgium and one in Luxembourg participated.

Pterocarpan synthase (PTS) structures suggest a common quinone methide-stabilizing function in dirigent proteins and proteins with dirigent-like domains.

The biochemical activities of dirigent proteins (DPs) give rise to distinct complex classes of plant phenolics. DPs apparently began to emerge during the aquatic-to-land transition, with phylogenetic analyses revealing the presence of numerous DP subfamilies in the plant kingdom. The vast majority (>95%) of DPs in these large multigene families still await discovery of their biochemical functions.

Pinoresinol-lariciresinol reductase: Substrate versatility, enantiospecificity, and kinetic properties.

Two western red cedar pinoresinol-lariciresinol reductase (PLR) homologues were studied to determine their enantioselective, substrate versatility, and kinetic properties. PLRs are downstream of dirigent protein engendered, coniferyl alcohol derived, stereoselective coupling to afford entry into the 8- and 8'-linked furofuran lignan, pinoresinol. Our investigations showed that each PLR homolog can enantiospecifically metabolize different furofuran lignans with modified aromatic ring substituents, but where phenolic groups at both C4/C4' are essential for catalysis.
