The extensive, diverse communities that constitute the microbiome are increasingly appreciated as important regulators of human health and disease through inflammatory, immune, and metabolic pathways. We sought to elucidate pathways by which microbiota contribute to inflammatory, autoimmune cardiac disease. We employed an animal model of experimental autoimmune myocarditis (EAM), which results in inflammatory and autoimmune pathophysiology and subsequent maladaptive cardiac remodeling and heart failure. Antibiotic dysbiosis protected mice from EAM and fibrotic cardiac dysfunction...

REVIEW
Sagar S Patel, Aaron T Gerds
Quality of life (QOL) and symptom burden are important measures captured by patient-reported outcomes (PROs). Myelodysplastic and myelodysplastic/myeloproliferative (MDS/MPN) neoplasm overlap syndromes are notable for significant morbidity and mortality, including a wide spectrum of physical and psychosocial effects. Thus, the development and application of PROs can provide meaningful information to facilitate communication and assist in follow up care. Disease-specific measures can more accurately reflect the full breadth of functional restrictions and symptoms...

Anxiety is linked to deficits in structural and functional connectivity between limbic structures and pre-frontal cortices. We employed a monozygotic (MZ) twin difference design to examine the relationship between structural characteristics of the uncinate fasciculus (UF) measured by Diffusion Tensor Imaging (DTI) and anxiety symptoms in a sample of N = 100 monozygotic (genetically identical), adolescent twins. The MZ difference design allowed us focus on environmental factors that vary within twin pairs while controlling for genetic and environmental factors shared by twin pairs...

Analysis of Ag-specific CD4(+) T cells in mycobacterial infections at the transcriptome level is informative but technically challenging. Although several methods exist for identifying Ag-specific T cells, including intracellular cytokine staining, cell surface cytokine-capture assays, and staining with peptide:MHC class II multimers, all of these have significant technical constraints that limit their usefulness. Measurement of activation-induced expression of CD154 has been reported to detect live Ag-specific CD4(+) T cells, but this approach remains underexplored and, to our knowledge, has not previously been applied in mycobacteria-infected animals...

BACKGROUND: Signing Deaf South Africans have limited access to health information. As a result, their knowledge about health is limited. Cell phone usage in South Africa is high. This study aimed to assess whether a short message service (SMS)-based health promotion campaign could improve Deaf people's knowledge of hypertension and healthy living. Additionally, the study aimed to assess the acceptability of using SMSs for health promotion targeting Deaf people. METHODS: A baseline questionnaire assessed participants' knowledge about hypertension before an SMS-based information campaign was conducted...

G-protein-coupled receptors (GPCRs) are one of the most tractable classes of drug targets. These dynamic proteins can adopt multiple active states that are linked to distinct functional outcomes. Such states can be differentially stabilized by ligands interacting with the endogenous agonist-binding orthosteric site and/or by ligands acting via spatially distinct allosteric sites, leading to the phenomena of 'biased agonism' or 'biased modulation'. These paradigms are having a major impact on modern drug discovery, but it is becoming increasingly apparent that 'kinetic context', at the level of both ligand-receptor and receptor-signal pathway kinetics, can have a profound impact on the observation and quantification of these phenomena...

BACKGROUND: An increasing number of options exist for the treatment of severe symptomatic aortic stenosis. The study aim was to compare short-term outcomes in patients undergoing surgical aortic valve replacement (SAVR), minimally invasive aortic valve replacement (MIAVR), and transcatheter aortic valve replacement (TAVR). METHODS: A multi-institutional retrospective review of 2,571 patients undergoing SAVR (n = 842), MIAVR via right anterior thoracotomy (n = 699) and TAVR (n = 1,030) between 2011 and 2014 was conducted...

The use of cost-effective vaccines capable of inducing robust CD8(+) T cell immunity will contribute significantly towards the elimination of persistent viral infections and cancers worldwide. We have previously reported that a cytolytic DNA vaccine encoding an immunogen and a truncated mouse perforin (PRF) protein significantly augments anti-viral T cell (including CD8(+) T cell) immunity. Thus, the current study investigated whether this vaccine enhances activation of dendritic cells (DCs) resulting in greater priming of CD8(+) T cell immunity...

BACKGROUND: Adoptive T-cell therapy relying on conventional T cells transduced with T-cell receptors (TCRs) or chimeric antigen receptors (CARs) has caused substantial tumor regression in several clinical trials. However, genetically engineered T cells have been associated with serious side-effects due to off-target toxicities and massive cytokine release. To obviate these concerns, we established a protocol adaptable to GMP to expand and transiently transfect γ/δ T cells with mRNA...

Leveraging structural biology tools, we report the results of experimentsseeking to determine if the different mechanical properties of DNA polymers with base analog substitutions can be attributed, at least in part, to induced changes from classical B-form DNA. The underlying hypothesis is that different inherent bending and twisting flexibilities may characterize non-canonical B-DNA, so that it is inappropriate to interpret mechanical changes caused by base analog substitution as resulting simply from 'electrostatic' or 'base stacking' influences without considering the larger context of altered helical geometry...

The reaction of 249Bk(OH)4 with iodate under hydrothermal conditions results in the formation of Bk(IO3)3 as the major product with trace amounts of Bk(IO3)4 also crystallizing from the reaction mixture. The structure of Bk(IO3)3 consists of nine-coordinate BkIII cations that are bridged by iodate anions to yield layers that are isomorphous with those found for AmIII, CfIII, and with lanthanides that possess similar ionic radii. Bk(IO3)4 was expected to adopt the same structure as M(IO3)4 (M = Ce, Np, Pu), but instead parallels the structural chemistry of the smaller ZrIV cation...

To support integration of clinical and research data, the makers of REDCap, a widely-used electronic data capture system, released the Dynamic Data Pull (DDP) module. Although DDP is a standard module in REDCap, institutions must develop custom middleware web services to exchange data between REDCap and local source systems. The lack of middleware is a barrier to institutional adoption and use by investigators. To overcome this gap, we developed a REDCap DDP web service middleware (accessible at https://github...

For a vaccine to be effective it must induce a sufficiently robust and specific immune response. Multi-site injection protocols can increase the titers of rabies virus-neutralizing antibodies. Hypothetically, spreading a vaccine dose across multiple lymphatic drainage regions could also potentiate T cell responses. We used a replication-deficient adenovirus serotype 5-vectored cancer vaccine targeting the melanoma-associated antigen dopachrome tautomerase. Clinically, high numbers of tumor-infiltrating CD8(+) T cells are a positive prognostic indicator...

BACKGROUND: High blood pressure is increasing worldwide, disproportionately so in developing countries. Inadequate health care systems and adoption of unhealthy lifestyles have been linked to this emergent pattern. To better understand this trend, it is imperative we measure prevalence of hypertension, and examine specific risk factors, at a local level. This study provides a cross-sectional view of urban residents of Arusha City to determine prevalence and associated risk factors. METHODS: Blood pressure was measured using a digital sphygmomanometer...

Many clinical human leukocyte antigen (HLA) laboratories are adopting next-generation sequencing (NGS) technology for HLA genotyping. There have been several reports of the cost-benefit and reduction in turn-around-time provided by NGS. Ninety-six percent of buccal swabs and peripheral blood samples had reportable HLA genotyping by NGS. The HLA loci most likely to fail genotyping from buccal swabs were DQB1, DPB1, and DPA1. Successful buccal swab samples had significantly less genomic DNA fragmentation compared to buccal swab samples that were unsuccessful...

The scramble for available places to study medicine in Germany continues. One of the core points within the "Master Plan 2020", which has been recently adopted, is the reform of teaching concepts at German medical faculties. In the future, students of human medicine are to be trained primarily based upon competence-oriented, integrated curricula. The present paper is intended to present modern teaching concepts and methods, as well as current examination formats, which play a special role in student training in orthopaedics and traumatology...

Optimal approaches to differentiate tumor antigen-specific cytotoxic T lymphocytes (CTLs) from pluripotent stem cells (PSCs) remain elusive. In the current study, we showed that combination of in vitro priming through Notch ligands and in vivo development facilitated the generation of tumor Ag-specific CTLs that effectively inhibited tumor growth. We co-cultured the murine induced PSCs (iPSCs) genetically modified with tyrosinase-related protein 2 (TRP2)-specific T cell receptors with OP9 cell line expressing both Notch ligands Delta-like 1 and 4 (OP9-DL1/DL4) for a week before adoptively transferred into recipient C67BL/6 mice...
