N-ChIP assays were also able to detect several other types of chromatin interactions including those with Dlx homeodomain factors and nuclear proteins such as Sin3a that lack an intrinsic DNA-binding motif Selleckchem Momelotinib and, therefore, bind to chromatin via interactions with other proteins.”
“Purpose: To investigate the heart position variability in deep-inspiration breath-hold (DIBH) radiation therapy (RT) for breast cancer when 3D surface imaging would be

used for monitoring the BH depth during treatment delivery. For this purpose, surface setup data were compared with heart setup data.\n\nMaterials and methods: Twenty patients treated with DIBH-RT after breast-conserving surgery were included. Retrospectively, heart registrations Rigosertib were performed for cone-beam computed tomography (CBCT) to planning CT. Further, breast-surface

registrations were performed for a surface, captured concurrently with CBCT, to planning CT. The resulting setup errors were compared with linear regression analysis. Furthermore, geometric uncertainties of the heart (systematic [Sigma] and random [sigma]) were estimated relative to the surface registration. Based on these uncertainties planning organ at risk volume (PRV) margins for the heart were calculated: 1.3 Sigma – 0.50 sigma.\n\nResults: Moderate correlation between surface and heart setup errors was found: R-2 = 0.64, 0.37, 0.53 in left-right (LR), cranio-caudal (CC), and in anterior-posterior (AP) direction, respectively. When surface imaging would be used for monitoring, the geometric uncertainties of the heart (cm) are [Sigma = 0.14, sigma = 0.14]; [Sigma = 0.66, sigma = 0.38]; [Sigma = 0.27, sigma = 0.19] in LR; CC; AP. This results in PRV margins of 0.11; 0.67; JQ1 Epigenetics inhibitor 0.25 cm in LR; CC; AP.\n\nConclusion: When DIBH-RT after breast-conserving surgery is guided by the breast-surface position then PRV margins should be used to take into account the heart-position variability relative to the breast-surface.

“Objective: the partograph is a tool used globally to record labour progress. Although it has the potential to improve maternal and neonatal outcomes, some midwives struggle with using it in practice. Training in partograph use is limited, and the theory is often divorced from practice. Innovative ways of improving training are urgently required. We therefore aimed to determine whether the use of an e-learning tool is beneficial for learning partograph skills.\n\nDesign: an uncontrolled before-and-after study was conducted, informed by Kirkpatrick’s four-stage model of evaluation; we report on the first two stages. We included a cohort of third and fourth year midwifery students who were studying at one university in Nairobi.
