Tumour derived fibroblasts (TDFs) differ functionally from normal fibroblasts (NDFs), and play a pivotal role in cancer. Many of the differences persist through subculture. We measured the DNA methylation profiles of 10 TDFs from OAC with 12 NDF from normal oesophageal mucosa using Infinium HumanMethylation450 Beadchips and found they differed in multidimensional scaling analysis. We identified 4,856 differentially methylated CpGs (DMCs, adjusted p  0.15), of which 3,243 (66.8%) were hypomethylated in TDFs compared to NDFs. Hypermethylated DMCs were enriched at transcription start sites (TSSs) and in CpG islands, and depleted in transcriptional enhancers. Gene ontology analysis of genes with DMCs at TSSs revealed an enrichment of genes involved in development, morphogenesis, migration, adhesion, regulation of processes and response to stimuli. Alpha-smooth muscle actin (α-SMA) is a marker of activated fibroblasts and a poor prognostic indicator in OAC. Hypomethylated DMCs were observed at the TSS of transcript variant 2 of α-SMA, which correlated with an increase in α-SMA protein expression. These data suggest that DNA methylation may contribute to the maintenance of the TDF phenotype

Confronting compositional confusion through the characterisation of the sub-Neptune orbiting HD 77946

We report on the detailed characterization of the HD 77946 planetary system. HD 77946 is an F5 ($M_*$ = 1.17 M$_{\odot}$, $R_*$ = 1.31 R$_{\odot}$) star, which hosts a transiting planet recently discovered by NASA's Transiting Exoplanet Survey Satellite (TESS), classified as TOI-1778 b. Using TESS photometry, high-resolution spectroscopic data from HARPS-N, and photometry from CHEOPS, we measure the radius and mass from the transit and RV observations, and find that the planet, HD 77946 b, orbits with period $P_{\rm b}$ = $6.527282_{-0.000020}^{+0.000015}$ d, has a mass of $M_{\rm b} = 8.38\pm{1.32}$M$_\oplus$, and a radius of $R_{\rm b} = 2.705_{-0.081}^{+0.086}$R$_\oplus$. From the combination of mass and radius measurements, and the stellar chemical composition, the planet properties suggest that HD 77946 b is a sub-Neptune with a $\sim$1\% H/He atmosphere. However, a degeneracy still exists between water-world and silicate/iron-hydrogen models, and even though interior structure modelling of this planet favours a sub-Neptune with a H/He layer that makes up a significant fraction of its radius, a water-world composition cannot be ruled out, as with $T_{\rm eq} = 1248^{+40}_{-38}~$K, water may be in a supercritical state. The characterisation of HD 77946 b, adding to the small sample of well-characterised sub-Neptunes, is an important step forwards on our journey to understanding planetary formation and evolution pathways. Furthermore, HD 77946 b has one of the highest transmission spectroscopic metrics for small planets orbiting hot stars, thus transmission spectroscopy of this key planet could prove vital for constraining the compositional confusion that currently surrounds small exoplanets

Influence of firm size on the competencies required to management engineers in the Jordanian telecommunications sector

This is an Accepted Manuscript of an article published by Taylor & Francis in European Journal of Engineering Education on [13 jun 2016], available online:http://www.tandfonline.com/ doi/abs/10.1080/03043797.2016.1197890.[EN] The objective of this study is to identify the competencies required to achieve success in the transition from higher education to the labour market based on the perceptions of employers. This paper analyses the assessments made by a group of engineering company employers. An item-battery of 20 competencies was grouped into 3 dimensions by using factor analysis. Subsequently, respondents scores were also clustered into three groups and characterised through contingency tables. The competencies demanded by employers were grouped into business and finance, problem-solving and strategic planning. Significant differences were found between responses from employers working in medium and small companies, who placed more importance on competencies related to problem-solving and strategic planning, and employers in big companies, who were more concerned about the difficulties of finding well-trained graduates. The findings from this paper have important implications for research in the areas of higher education and organisations that usually employ graduate engineers.The authors would like to thank the Education, Audiovisual and Culture Executive Agency (EACEA) [Tempus program.

Un programme court de TCCi en groupe par visioconférence dans l'insomnie modifie-t-il les croyances erronées ?

International audienceIntroduction: The Morphee Sleep network runs a short group CBT programme. During the pandemic, the programme was administered by videoconference. The programme focuses on behavioral modification. The objective of our study was to evaluate whether the videoconference programme produced changes in dysfunctional beliefs about sleep and whether these changes were linked to improvements in insomnia. Methods: Observational study of 3 × 90 minute sessions of group CBT by videoconference over one month delivered by experienced psychologists. The outcome measures : insomnia severity scale (ISI), dysfunctional beliefs and attitudes about sleep short version (DBAS 16), hospital anxiety and depression scale (subscales depression HADD and anxiety HADA), and epworth sleepiness scale (ESS) completed before session 1 and at the end of session 3. The effectiveness of the programme on insomnia was evaluated by the decrease in the ISI score : full response R+ (>7 points), partial response, R- (4 - 6 points) non response, NR (9 points) and no response CNR (<9 points). Results: There were fifty-five participants, 64 % women with a mean age of 49.1 ± 16.1 years. The DBAS 16 was reduced by 6.12 ± 1.29 to 5.09 ± 1.57 (P< 0.0001) with 67 % of participants showing a response CR. The ISI score reduced from 17.7 ± 3.6 to 14.0 ± 4.9 (P< 0.0001) with 49 % showing at least a partial response (R+ and R-). A significant correlation (0.327, P = 0.015) between the CBT response and dysfunctional beliefs about sleep was observed with a significant reduction in the DBAS 16 between responders R+ and non-responders (R+ vs. NR 1.67 ± 1.3 vs. 0.57 ± 1.28 P = 0.012). Seventy-nine of R+ showed improvements in the DBAS 16 vs. 69 % of R- and 61 % of non-responders NR. Conclusion: A short group CBT programme by videoconference focused on behavioral modification can reduce dysfunctional beliefs about sleep

Modular Sensor Architecture for Unobtrusive Routine Clinical Diagnosis

Clinical diagnosis of pathological conditions is accomplished regularly via the recording and subsequent analysis of a physiological variable from a subject. Problems with current common practice centre around the obtrusive and rigid nature of this process. These include the length, timing and location of the diagnostic recording session, transfer of data to clinical staff, liaison between clinical staff and subjects and the integration of such diagnostic check-ups into the overall health care process
