question:
To explore the effect of arsenic trioxide (As2O3) on the growth inhibition of imatinib (IM)-resistant bcr-abl mutant cell lines in vitro.', 'Cell growth of one IM-sensitive cell line, 32Dp210 and 15 IM-resistant cell lines including T315I and other 14 bcr-abl mutants were detected by MTT assay after treatment with IM and As2O3. The cell lines with 5 frequently observed mutants in CML patients were analyzed for apoptosis by flow cytometry with Annexin V and PI staining as well as the expression of bcr-abl fusion protein, phosphorylated CRKL protein and apoptosis-related proteins by Western blot.', 'The fifty percent inhibition concentration (IC50) values of As2O3 for 15 IM-resistant cell lines were 2.6-5.3 fold lower than that for IM-sensitive cell line. For the 5 bcr-abl mutants frequently happened in CML patients, As2O3 significantly inhibited the expression of bcr-abl fusion protein and phosphorylated CRKL and induced apoptosis in a dose-dependent manner as compared with that for 32Dp210. Coincidently, the cell apoptosis was induced through caspase-3, 8 and 9 pathways.
answer:
Does [ Arsenic trioxide inhibit cell growth in imatinib-resistant bcr-abl mutant cell lines in vitro ]?


question:
Pigs are frequently used as animal models in experimental medicine. To identify processes of vascular development or regression, vascular elements must be recognised and quantified in a three-dimensional (3D) arrangement. Vascular corrosion casts enable the creation of 3D replicas of vascular trees. The aim of our study was to identify suitable casting media and optimise the protocol for porcine liver vascular corrosion casting.', 'Mercox II® (Ladd Research, Williston, Vermont, USA) and Biodur E20® Plus (Biodur Products, Heidelberg, Germany) were tested in 4 porcine livers. The resins (volume approximately 700 mL) were injected via the portal vein. Corrosion casts were examined by macro-computed tomography, micro-computed tomography and scanning electron microscopy.', 'For hepatectomies, the operating protocol was optimised to avoid gas or blood clot embolisation. We present a protocol for porcine liver vascular bed casting based on corrosion specimens prepared using Biodur E20® epoxy resin.
answer:
Does porcine liver vascular bed in Biodur E20 corrosion cast?


question:
Laparoscopic ventral hernia repair (LVHR) is associated with shorter hospitalization and lower complication rates compared to open ventral hernia repair. We sought to determine if hernia-related factors, such as defect size and re-operative status correlate with postoperative complications, operative times and length of stay (LOS).', 'The study is a retrospective review of 30-day perioperative outcomes following LVHR in 91 patients who underwent surgery at a single institution from August 2009 through June 2012. A single surgeon performed all procedures.', 'Indications for surgery were recurrent incisional hernia in 33\xa0% of patients and primary incisional or ventral abdominal hernias in the rest. Coated polyester mesh with an average size of 348\xa0cm(2) (±214; range 113-1,036) was used. Mean operative time was 132\xa0min (±66.1; range 53-412). The mean LOS was 4.0\xa0days (±3.5; range 1-22). Complications occurred in 13 patients for overall morbidity of 16.5\xa0% and no mortality. There was one recurrence in 30\xa0days (1.1\xa0%). Patients who had a surgery >120\xa0min or a LOS >1\xa0day were statistically more likely to have multiple hernias, larger defect sizes (>40\xa0cm(2)), larger mesh sizes (>300\xa0cm(2)) or a history of recurrent hernia (P\xa0<\xa00.05). No other clinical or demographic variable evaluated in this study correlated with operative time or LOS.
answer:

Does laparoscopic hernia complexity predict operative time and length of stay?
