Abstract
Scaffold materials used for bone defect repair are often limited by osteogenic efficacy. Moreover, microRNAs (miRNAs) are involved in regulating the expression of osteogenic-related genes. In previous studies, we verified the enhancement of osteogenesis using a grooved porous hydroxyapatite scaffold (HAG). In the present study, we analyzed the contribution of HAG to the osteogenic differentiation of human placenta-derived mesenchymal stem cells (hPMSCs) from the perspective of miRNA differential expression. Furthermore, results showed that miRNAs were differentially expressed in the osteogenic differentiation of hPMSCs cocultured with HAG. In detail, 16 miRNAs were significantly upregulated and 29 miRNAs were downregulated with HAG. In addition, bioinformatics analyses showed that the differentially expressed miRNAs were enriched in a variety of biological processes, including signal transduction, cell metabolism, cell junctions, cell development and differentiation, and that they were associated with osteogenic differentiation through axon guidance, mitogen-activated protein kinase, and the transforming growth factor beta signaling pathway. Furthermore, multiple potential target genes of these miRNAs were closely related to osteogenic differentiation. Importantly, overexpression of miR-146a-5p (an upregulated miRNA) promoted the osteogenic differentiation of hPMSCs, and miR-145-5p overexpression (a downregulated miRNA) inhibited the osteogenic differentiation of hPMSCs.

Abstract
BACKGROUND Rapid administration of appropriately indicated antibiotics is crucial in septic patients. Sepsis data supports that there is a higher risk of mortality for each hour delay from triage to antibiotic therapy, as well as for inappropriate antibiotic selection. There are a variety of rapid microbial detection systems, such as VERIGENE®, used in acute care facilities to rapidly detect bacteremia and identify resistance markers. Our study investigates the usefulness of VERIGENE® assays in accurately detecting Gram-positive and Gram-negative pathogens when compared to traditional blood culture analysis systems, such as VITEK®. METHODS 819 Gram-positive and 373 Gram-negative blood samples were collected and tested using both VERIGENE® and VITEK®. Statistical tests were two-tailed and observations were defined as statistically significant if P ≤ 0.05. RESULTS VERIGENE® detected a pathogen in 816/819 (99.6%) samples of the Gram-positive blood cultures and 367/373 (98.3%) samples of the Gram-negatives compared to 805/819 (98.3%) and 367/373 (98.4%), respectively, using VITEK®. Gram-positive cultures had a sensitivity of 99.5% and a specificity of 27.3% (PPV 99.0%, NPV 42.9%, 98.7% accuracy) with VERIGENE analysis. Gram-negatives had a sensitivity of 99.2% and a specificity of 20.0% (PPV 98.9%, NPV 25.0%, 98.4% accuracy). CONCLUSIONS Although statistically insignificant (P = 0.25), VERIGENE® was 1.3% more likely to identify Gram-positive bacteria when compared to conventional methods. Overall, we concluded that VERIGENE® assays are valuable in their ability to rapidly detect microorganisms and resistance markers, given their high sensitivities. This allows for select targeted therapy in patients with sepsis and can ultimately reduce mortality rates.

Abstract
Changes that occur within oviducts after fertilization are dependent on post-ovulation events, including oocyte-oviduct interactions. Although general processes are well-defined, the molecular basis are poorly understood. Recently, new marker genes involved in ‘cell development’, ‘cell growth’, ‘cell differentiation’ and ‘cell maturation’ processes have been identified in porcine oocytes. The aim of the study was to assess the expression profile of genes in primary in vitro cultured oviductal epithelial cells (OECs), clustered in Gene Ontology groups which enveloped markers also identified in porcine oocytes. OECs (from 45 gilts) were surgically removed and cultured in vitro for ≤ 30 days, and then subjected to molecular analyses. The transcriptomic and proteomic profiles of cells cultured during 7, 15 and 30 days were investigated. Additionally, morphological/histochemical analyzes were performed. The results of genes expression profiles were validated after using RT-qPCR. The results showed a significant upregulation of UNC45B, NOX4, VLDLR, ITGB3, FMOD, SGCE, COL1A2, LOX, LIPG, THY1 and downregulation of SERPINB2, CD274, TXNIP, CELA1, DDX60, CRABP2, SLC5A1, IDO1, ANPEP, FST. Detailed knowledge of the molecular pathways occurring in the OECs and the gametes that contact them may contribute both to developments of basic science of physiology, and new possibilities in advanced biotechnology of assisted reproduction.

Abstract
BACKGROUND The aerial parts of land plants are covered with cuticular waxes that limit non-stomatal water loss and gaseous exchange, and protect plants from ultraviolet radiation and pathogen attack. This is the first report on the characterization and genetic mapping of a novel dominant glossy mutant (BnaA.GL) in Brassica napus. RESULTS Transmission electron microscopy revealed that the cuticle ultrastructure of GL mutant leaf and stem were altered dramatically compared with that of wide type (WT). Scanning electron microscopy corroborated the reduction of wax on the leaf and stem surface. A cuticular wax analysis of the GL mutant leaves further confirmed the drastic decrease in the total wax content, and a wax compositional analysis revealed an increase in aldehydes but a severe decrease in alkanes, ketones and secondary alcohols. These results suggested a likely blockage of the decarbonylation step in the wax biosynthesis pathway. Genetic mapping narrowed the location of the BnaA.GL gene to the end of A9 chromosome. A single-nucleotide polymorphism (SNP) chip assay in combination with bulk segregant analysis (BSA) also located SNPs in the same region. Two SNPs, two single sequence repeat (SSR) markers and one IP marker were located on the flanking region of the BnaA.GL gene at a distance of 0.6 cM. A gene homologous to ECERIFERUM1 (CER1) was located in the mapped region. A cDNA microarray chip assay revealed coordinated down regulation of genes encoding enzymes of the cuticular wax biosynthetic pathway in the glossy mutant, with BnCER1 being one of the most severely suppressed genes. CONCLUSIONS Our results indicated that surface wax biosynthesis is broadly affected in the glossy mutant due to the suppression of the BnCER1 and other wax-related genes. These findings offer novel clues for elucidating the molecular basis of the glossy phenotype.
