BACKGROUND: Esophageal squamous carcinoma (ESC) is one of the most fatal malignancies worldwide with increasing occurrences yet poor outcome. MicroRNAs were reported to play roles in ESC. AIMS: We aimed to understand how miRNAs affect the radiotherapy resistance of ESC. METHODS: MicroRNA assays, real-time PCR, and Western blot were performed for expression analysis of miR-93 and BTG3. Luciferase activity assay was conducted with mutated B-cell translocation gene 3 (BTG3) 3'-UTR sequence in the 3' end of luciferase sequence with miR-93 inhibitor...

Ian M Graham, Alberico L Catapano
PURPOSE OF REVIEW: An examination of the current ACC/AHA and ESC/EAS Guidelines on the management of dyslipidemias for common ground and differences. RECENT FINDINGS: There is much common ground. Both note that ASCVD is, in most people, the product of a number of risk factors, notably tobacco exposure, hyperlipidemia, hypertension, inactivity, overweight and diabetes. They stress that risk calculators can help in the assessment of risk in apparently healthy persons...

This study aims to review pediatric pulmonary hypertension (PH) by comparing the guidelines of the European Society of Cardiology (ESC)/European Respiratory Society (ERS), the American Heart Association (AHA)/American Thoracic Society (ATS), and the European Pediatric Pulmonary Vascular Disease Network (EPPVDN). All three sets of guidelines define PH as having a mean pulmonary artery pressure of ≥25 mmHg and accept the validity of the World Health Organization (WHO) classification system. Every child with a high index of suspicion for PH should undergo an initial work-up of chest X-rays, electrocardiography, and echocardiography...

Data from in vitro and in vivo models suggest that malnutrition and stress trigger adaptive responses, leading to small for gestational age (SGA) blastocysts with fewer cell numbers. These stress responses are initially adaptive, but become maladaptive with increasing stress exposures. The common stress responses of the blastocyst-derived stem cells, pluripotent embryonic and multipotent placental trophoblast stem cells (ESCs and TSCs), are decreased growth and potency, and increased, imbalanced and irreversible differentiation...

Ca2+ signals participate in various cellular processes with spatial and temporal dynamics, among which, inositol 1,4,5-trisphosphate receptors (IP3Rs)-mediated Ca2+ signals are essential for early development. However, the underlying mechanisms of IP3R-regulated cell fate decision remain largely unknown. Here we report that IP3Rs are required for the hematopoietic and cardiac fate divergence of mouse embryonic stem cells (mESCs). Deletion of IP3Rs (IP3R-tKO) reduced Flk1+/PDGFRα- hematopoietic mesoderm, c-Kit+/CD41+ hematopoietic progenitor cell population, and the colony-forming unit activity, but increased cardiac progenitor markers as well as cardiomyocytes...

Although numbers of cancer cell lines have been shown to be successfully reprogrammed into induced pluripotent stem cells (iPSCs), reprogramming Oral Squamous Cell Carcinoma (OSCC) to pluripotency in relation to its cancer cell type and the expression pattern of pluripotent genes under later passage remain unexplored. In our study, we reprogrammed and characterised H103 and H376 oral squamous carcinoma cells using retroviral OSKM mediated method. Reprogrammed cells were characterized for their embryonic stem cells (ESCs) like morphology, pluripotent gene expression via quantitative real-time polymerase chain reaction (RT-qPCR), immunofluorescence staining, embryoid bodies (EB) formation and directed differentiation capacity...

The latest European Society of Cardiology (ESC) guidelines for the diagnosis and management of heart failure include a new patient group for those with heart failure with mildly reduced ejection fraction (HFmrEF). By defining this group of patients as a separate entity, the ESC hope to encourage more research focusing on patients with HFmrEF. Previously, patients with this condition were caught between two classifications-heart failure with reduced ejection fraction and heart failure with preserved ejection fraction...

Endometriosis is an inflammatory disease and nuclear receptors play a crucial role in mediating the inflammatory response. In endometrial stromal cells (ESC), nuclear receptors expression can be influenced by the local environment. Progestins are first-line, on-label treatments of endometriosis that may have direct effects on endometriotic lesions through these nuclear receptors. Therefore, we investigated whether there was an association between nuclear receptors expression and the influence of progestins on inflammatory cytokines production in a preliminary, in vitro study with primary cultures...

Escherichia coli resistant to extended-spectrum cephalosporins (ESC) are widely distributed in Norwegian broiler production, and the majority harbour transferable IncK or IncI1 plasmids with blaCMY-2 Persistent occurrence in broiler farms may occur through survival of ESC-resistant E. coli in the farm environment, or by transfer and maintenance of resistance plasmids within a population of environmental bacteria with high survival abilities. The aim of this study was to determine the transferability of two successful blaCMY-2 carrying plasmids belonging to the incompatibility groups IncK and IncI1, into E...

Serum- and 2i-cultured embryonic stem cells (ESCs) show different epigenetic landscapes and transcriptomic profiles. The difference in the function and expression of microRNAs (miRNAs) between these two states remains unclear. Here, we showed that 2i- and serum-cultured ESCs exhibited distinctive miRNA expression profiles with >100 miRNAs differentially expressed, and the expression changes were largely due to transcriptional regulation. We further characterized the function of miRNAs differentially expressed under two conditions and found that ESCs exhibited higher degree of dependency on miRNAs for rapid proliferation; since Dgcr8(-/-) or Dicer1(-/-) but not wild-type ESCs showed slower growth rate and more accumulation in the G1 phase under 2i than serum condition...

Recruitment of transcription factors (TFs) to repressed genes in euchromatin is essential to activate new transcriptional programs during cell differentiation. However, recruitment of all TFs, including pioneer factors, is impeded by condensed H3K27me3-containing chromatin. Single-cell and gene-specific analyses revealed that, during the first hours of induction of differentiation of mammalian embryonic stem cells (ESCs), accumulation of the repressive histone mark H3K27me3 is delayed after DNA replication, indicative of a decondensed chromatin structure in all regions of the replicating genome...

OBJECTIVE Endoscopic strip craniectomy (ESC) with postoperative helmet orthosis is a well-established treatment option for sagittal craniosynostosis. There are many technical variations to the surgery ranging from simple strip craniectomy to methods that employ multiple cranial osteotomies. The purpose of this study was to determine whether the addition of lateral barrel-stave osteotomies during ESC improved morphological outcomes. METHODS An IRB-approved retrospective review was conducted on a consecutive series of cases involving ESC for sagittal craniosynostosis at 2 different institutions from March 2008 to August 2014...

Induced pluripotent stem cells (iPSC) are somatic cells reprogrammed to pluripotency by forced expression of pluripotency factors. These cells are shown to have the same pluripotent potential as embryonic stem cells (ESC) and considered as an alternative to the much controversial usage of ESC which involved human embryos. However, the traditional method in reprogramming cells into iPSC using genome-integrating retro- or lenti- viruses remains an obstacle for its application in clinical setting. Although numerous studies have been conducted for a safer DNA-based reprogramming, reprogramming of iPSC by genetic modifications may raise the possibility of malignant transformation and has been a major limitation for its usage in clinical applications...

Embryonic stem cells (ESCs), due to their intrinsic capability to generate somatic cells of all three germ layers, are potential sources of neural cells for cell replacement therapies. However, the empirical differentiation protocols and the lack of mechanistic understanding of the neural differentiation of ESCs have limited the utility of ESCs as a developmental model or as a cell source for neural cell populations for replacement therapies. Co-culturing ESCs with stromal cells is one of the extensively used methods to induce neural differentiation...
