#1
Mikko Pakarinen
Transanal pull-through is currently one of the most commonly used operation to treat Hirschsprung's disease (HD) worldwide. It has undergone some technical modifications during the last decades and still contains variable surgical practices. As high quality comparative studies between different surgical approaches are missing, debate over the optimal operation for HD still continues. Transanal pull-through is associated with multiple potential complications, which may result in permanently impaired functional outcome, life-long morbidity, and significant social restrictions...

BACKGROUND: Intra-operative estimation of stem anteversion in total hip arthroplasty (THA) using postero-lateral approach is made by the surgeon's visual assessment, using the tibia as a guide, with the assumption that tibial axis is vertical to the trans-epicondylar axis. However, the accuracy of the intra-operative estimation has rarely been verified with postoperative CT-scans, with controversies regarding these measurements particularly in case of knee osteoarthritis. Therefore we performed a prospective study to: 1) determine the accuracy of the intra-operative measurement and 2) investigate factors affecting the discrepancy between the surgeon's estimation and the real stem anteversion HYPOTHESIS: Intra-operative estimation of stem anteversion correlated with the real stem anteversion on CT scan...

Mingyi Chen, Rebecca E Lacey
BACKGROUND: The relationship between adverse childhood experiences (ACE) and poorer health across the life course is well established. Increased chronic inflammation might be one mechanism through which these associations operate. The aim of this study was to explore the relationship between ACE and adult inflammation using a prospective longitudinal study. We also investigated whether associations were explained by life course socioeconomic, psychological and health behavioural factors, and whether associations differed by gender...

Feature-based control processes guide attention towards objects with target features in visual search. While these processes are assumed to operate globally across the entire visual field, it remains controversial whether target-matching objects at task-irrelevant locations can be excluded from attentional selection, especially when spatial attention is already narrowly focused elsewhere. We investigated whether probe stimuli at irrelevant lateral locations capture attention when they precede search displays where targets are defined either by a specific feature (colour or orientation) or by a colour/orientation conjunction by measuring N2pc components (an electrophysiological marker of attentional target selection) to these probes...

BACKGROUND & AIMS: Guidelines for initiating colorectal cancer (CRC) screening are based on family history but do not consider lifestyle, environmental, or genetic risk factors. We developed models to determine risk of CRC, based on lifestyle and environmental factors and genetic variants, and to identify an optimal age to begin screening. METHODS: We collected data from 9748 CRC cases and 10,590 controls in the Genetics and Epidemiology of Colorectal Cancer Consortium and the Colorectal Transdisciplinary study, from 1992 through 2005...

Direct access to the root canals in posterior teeth for endodontic treatment is most frequently facilitated by the straightening of the coronal parts of the root canals, having as a consequence the relocation of the canal orifices on the map of the floor of the pulp chamber (Christie & Thompson, 1994). This procedure intentionally moves the coronal aspect of a canal away from the center of the chamber, while simultaneously removing internal dentin from the pulp chamber walls. The aim of this study was to evaluate the displacement resulting from the relocation of root canal orifices during the initial phase of rotary root canal treatment in molars using the dental operating microscope (DOM) and digital image processing...

Proteinase-activated receptor-2 (PAR-2) activation in basal keratinocytes stimulates inflammation via the Ca2+ -dependent production of mediators such as interleukin (IL)-1β, tumor necrosis factor (TNF)-α and thymic stromal lymphopoietin (TSLP). In this study, we investigated PAR-2 calcium signaling and the consequent production of inflammatory mediators in differentiated human primary keratinocytes (DhPKs). Stimulation with the PAR-2 activating peptide SLIGKV promoted Ca2+ store depletion in both undifferentiated human primary keratinocytes (UhPKs) and DhPKs...

Pectinase produced by a honey derived from the fungus Aspergillus awamori KX943614 was covalently immobilized onto gel beads made of alginate and agar. Polyethyleneimine, glutaraldehyde, loading time and enzyme's units were optimized by 24 full factorial central composite design (CCD). The immobilization process increased the optimal working pH for the free pectinase from 5 to a broader range of pH 4.5-5.5 and the optimum operational temperature from 55 °C to a higher temperature, of 60 °C, which is favored to reduce the enzyme's microbial contamination...

Transplantation is currently the therapy of choice for endstage organ failure even though it requires long-term immunossuppresive therapy, with its numerous side effects, for acceptance of the transplanted organ. In rare cases however, patients develop operational tolerance, that is, graft survival without immunosuppression. Studies conducted on these patients reveal genetic, phenotypic, and functional signatures. They provide a better understanding of the immunological mechanisms involved in operational tolerance and define biomarkers that could be used to adapt immunosuppressive treatment to the individual, safely reduce immunosuppression doses, and ideally and safely guide immunosuppression withdrawal...

In this paper, we examine the highest possible performance level of graphene nanoribbon field effect transistors (GNRFETs) for wide range of operation voltages and device structure parameters such as width of graphene nanoribbon and gate length. To achieve this goal, we formulated a self-consistent non-equilibrium Green's function (NEGF) method in conjunction with the Poisson equation. We model the operation of nanometer sized GNRFETs of which GNR channels have finite bandgaps so that the GNRFET can operate as a switch...
