Abstract To shed light on the mechanism of formation nanophase iron particles (npFe) in space‐weathered materials from airless bodies, we analyzed exsolved and unexsolved lunar pyroxenes Apollo 17 sample 71501. The pyroxene allowed for observation effects space weathering similar mineral phases with variable composition. Using coordinated scanning transmission electron microscopy energy‐dispers...
PURPOSE Human urothelial carcinoma is thought to arise from a field change that affects the entire urothelium. Multifocality of urothelial carcinoma is a common finding at endoscopy and surgery. Whether these coexisting tumors arise independently or are derived from the same tumor clone is uncertain. Molecular analysis of microsatellite alterations and X-chromosome inactivation status in the ce...
PURPOSE Low-grade serous ovarian carcinomas (LGSC) are Ras pathway-mutated, TP53 wild-type, and frequently associated with borderline tumors. Patients with LGSCs respond poorly to platinum-based chemotherapy and may benefit from pathway-targeted agents. High-grade serous carcinomas (HGSC) are TP53-mutated and are thought to be rarely associated with borderline tumors. We sought to determine whe...
SUZ12 is a core component of the polycomb repressive complex 2 (PRC2) and is required for the differentiation of mouse embryonic stem cells (ESCs). PRC2 is associated with transcriptional repression via methylation of H3 Lys-27. We applied quantitative mass spectrometry to investigate the effects of Suz12 deficiency on H3.2 and H3.3 from mouse ESCs. Using high mass accuracy MS combined with CID...
PURPOSE We evaluated the short- and long-term outcomes of laparoscopic total proctocolectomy with ileal pouch-anal anastomosis (TPC/IPAA) for treatment of familial adenomatous polyposis (FAP). Also, we assessed the oncologic outcomes in FAP patients with coexisting malignancy. METHODS From August 1999 to September 2010, 43 FAP patients with or without coexisting malignancy underwent TPC/IPAA ...
OBJECTIVE To determine the extent of maternal morbidity associated with in utero transfer. DESIGN Retrospective study of 190 consecutive cases over two years. SETTING Liverpool Maternity Hospital. PATIENTS 190 Pregnant women were transferred to the hospital under the in utero transfer arrangements from district general hospitals both within and outside the Mersey region. The women admitte...
BACKGROUND To support a hypothesis that there is an intrinsic interplay between coronary artery disease (CAD) and type 2 diabetes (T2D), we used RNA-seq to identify unique gene expression signatures of CAD, T2D, and coexisting conditions. METHODS After transcriptome sequencing, differential expression analysis was performed between each disordered state and normal control group. By comparing ...
BACKGROUND Health-related quality of life (HRQoL) is reduced after a burn, and is affected by coexisting conditions. The aims of the investigation were to examine and describe effects of coexisting disease on HRQoL, and to quantify the proportion of burned people whose HRQoL was below that of a reference group matched for age, gender, and coexisting conditions. METHOD A nationwide study cover...
Coexistence of hepatitis B surface antigen (HBsAg) and antibody against HBsAg (anti-HBs) comprises an atypical serological profile in patients with chronic hepatitis B virus (HBV) infection. In this study, in total 94 patients with coexisting HBsAg and anti-HBs and 94 age- and sex-matched patients with positive HBsAg were characterized by quantitatively measuring HBsAg and HBV DNA, sequencing l...
In this work the strange behavior of an impact oscillator with a one-sided elastic constraint discovered experimentally is compared with the predictions obtained using its mathematical model. Extensive experimental investigations undertaken on the rig developed at the Aberdeen University reveal different bifurcation scenarios under varying excitation frequency near grazing which were recorded f...
