Aims: The latest 2015 ESC Guidelines on the prevention of sudden cardiac death make a Class IIa recommendation for ICD implantation in patients listed for heart transplantation. This recommendation was based on expert consensus in view of the sparsity of data. Methods and results: All patients listed for heart transplantation at the University Hospitals of Leuven from 2002 until 2014 were studied retrospectively. Exclusion criteria were age <16 years, cardiac disease other than ischaemic or dilated cardiomyopathy and re-transplantation...

OBJECTIVE: There is a clinical need for early and accurate diagnosis of acute myocardial infarction (AMI). Current European Society of Cardiology (ESC) guidelines recommend diagnosis of non-ST-elevation AMI based on serial troponin measurements. We aimed to challenge the ESC guidelines using 1) a high-sensitivity troponin I (hs-TnI) baseline cutoff, 2) an absolute hs-TnI change after 1 hour and 3) additional application of an ischemic ECG. METHODS: 1,516 patients with suspected AMI presenting to the emergency department were included...

Stem cells (SCs - stem cells) are characterized by plasticity and the ability to differentiate into other cell types. They are obtained from bone marrow, peripheral blood and cord blood. Mesenchymal stem cells (MSCs) shows a broad immunomodulating, increases the number of regulatory T cells (Treg), modifies the activity of T cells, dendritic cells and NK (natural killer). Direct impact on reducing the release of proinflammatory cytokines and increased release of proinflammatory cytokines. Within the respiratory tract has a number of resident stem and progenitor cells referred to as L-MSCs (lung mesenchymal stem cells) whose presence was confirmed by markers as defined in the trachea, epithelial cells and alveolar...

STUDY QUESTION: How does hCG signal in human endometrial stromal cells (ESCs) and what is its role in regulating ESC function? SUMMARY ANSWER: CG signaling in ESCs activates the extracellular signal-regulated protein kinases 1 and 2 (Erk1/2) pathway through exchange protein activated by cAMP (Epac) and transiently increases progesterone receptor (PR) transcript and protein expression and its transcriptional function. WHAT IS KNOWN ALREADY: hCG is one of the earliest embryo-derived secreted signals in the endometrium, which abundantly expresses LH/hCG receptors...

Transition from symmetric to asymmetric cell division requires precise coordination of differential gene expression. We show that embryonic stem cells (ESCs) mainly express DIDO3 and that their differentiation after leukemia inhibitory factor withdrawal requires DIDO1 expression. C-terminal truncation of DIDO3 (Dido3ΔCT) impedes ESC differentiation while retaining self-renewal; small hairpin RNA-Dido1 ESCs have the same phenotype. Dido3ΔCT ESC differentiation is rescued by ectopic expression of DIDO3, which binds the Dido locus via H3K4me3 and RNA POL II and induces DIDO1 expression...

The chromatin of naive embryonic stem cells (ESCs) has a largely open configuration, as evident by the lack of condensed heterochromatin and the hypomethylation of DNA. Several molecular mechanisms promoting this constellation were previously identified. Here we present evidence for an important epigenetic function of MAD2L2, a protein originally known for its role in DNA damage repair, and for its requirement in germ cell development. We demonstrate using super-resolution microscopy that numerous MAD2L2 microfoci are exclusively associated with euchromatin, similar to other factors of the DNA damage response...

Wnt/β-catenin signaling is required for embryonic stem cell (ESC) pluripotency by inducing mesodermal differentiation and inhibiting neuronal differentiation; however, how β-catenin counter-regulates these differentiation pathways is unknown. Here, we show that lysine 49 (K49) of β-catenin is trimethylated (β-catMe3) by Ezh2 or acetylated (β-catAc) by Cbp. Significantly, β-catMe3 acts as a transcriptional co-repressor of the neuronal differentiation genes sox1 and sox3, whereas β-catAc acts as a transcriptional co-activator of the key mesodermal differentiation gene t-brachyury (t-bra)...

The emergence of antimicrobial resistance among Enterobacter spp., including resistance to extended-spectrum cephalosporins (ESC), is of great concern in both human and veterinary medicine. In this study, we investigated the prevalence of antimicrobial resistance among 60 isolates of Enterobacter spp., including E. cloacae (n = 44), E. aerogenes (n = 10), and E. asburiae (n = 6), from clinical specimens of dogs and cats from 15 prefectures in Japan. Furthermore, we characterized the resistance mechanisms harbored by these isolates, including extended-spectrum β-lactamases (ESBLs) and plasmid-mediated quinolone resistance (PMQR); and assessed the genetic relatedness of ESC-resistant Enterobacter spp...

Childhood maltreatment (CM) has been indicated as a predictor of a differential response to antidepressant treatment with psychotherapy compared to medication. In this secondary analysis, we investigated whether the presence of CM results in a differential indication for the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) or escitalopram plus clinical management (ESC). Sixty patients with chronic depression were randomized to either 22 sessions of CBASP or ESC over the course of 8 weeks of acute and 20 weeks of extended treatment at 2 German treatment sites...

We wish to identify determinants of endothelial lineage. Murine embryonic stem cells (mESC) were fused with human endothelial cells in stable, non-dividing, heterokaryons. Using RNA-seq it is possible to discriminate between human and mouse transcripts in these chimeric heterokaryons. We observed a temporal pattern of gene expression in the ESCs of the heterokaryons that recapitulated ontogeny, with early mesodermal factors being expressed before mature endothelial genes. A set of transcriptional factors not known to be involved in endothelial development was upregulated, one of which was POU class 3 homeobox 2 (Pou3f2)...

Chemokines are a superfamily of structurally related chemotactic cytokines exerting significant roles in regulating cell migration and activation. Based on the arrangement of the first four cysteine residues, they are classified into CC, CXC, C and CX3C subfamilies. In this study, a complete set of 64 CC chemokine ligand (CCL) genes was systematically identified, annotated, and characterized from the channel catfish genome. Extensive phylogenetic and comparative genomic analyses supported their annotations, allowing establishment of their orthologies, revealing fish-specific CC chemokines and the expansion of CC chemokines in the teleost genomes through lineage-specific tandem duplications...

Spermatogenic lineage has been directly generated in spermatogonial stem cell (SSC) conditions from human pluripotent stem cells (PSCs). However, it remains unknown whether mouse ESCs can directly differentiate into advanced male germ cell lineage in the same conditions. Here, we showed that rather low efficiency of germ-like cell generation from mouse ESCs in SSC conditions. Interestingly, addition of retinoic acid (RA) into SSC conditions enabled efficient differentiation of mouse ESCs into germ-like cells, as shown by activating the expression of spermatogenesis-associated genes during differentiation process, such as Mvh , Dazl , Prdm14 , Stella , Scp1 , Scp3 , Stra8 and Rec8 In contrast, for cells cultured in control medium, the activation of these above genes barely occurred...

Extended-spectrum β-lactamases (ESBLs) and plasmid mediated AmpC β-lactamases (pAmpC) are enzymes able to hydrolyze a large variety of β-lactam antibiotics, including 3(rd) generation cephalosporins and monobactams. Broilers and broiler meat products can be highly contaminated with ESBL and pAmpC-producing Escherichia coli, also known as extended-spectrum cephalosporins (ESC)-resistant E. coli, and can be a source for human infections. As few data are available on interventions to reduce ESC-resistant E...

The ring finger protein PCGF6 (polycomb group ring finger 6) interacts with RING1A/B and E2F6 associated factors to form a non-canonical PRC1 (polycomb repressive complex 1) known as PCGF6-PRC1. Here, we demonstrate that PCGF6-PRC1 plays a role in repressing a subset of PRC1 target genes by recruiting RING1B and mediating downstream mono-ubiquitination of histone H2A. PCGF6-PRC1 bound loci are highly enriched for promoters of germ cell-related genes in mouse embryonic stem cells (ESCs). Conditional ablation of Pcgf6 in ESCs leads to robust de-repression of such germ cell-related genes, in turn affecting cell growth and viability...
