1Through-needle all-optical ultrasound imaging in vivo: a preclinical swine study显示文摘High-frequency ultrasound imaging can provide exquisite visualizations of tissue to guide minimally invasive procedures.Here,we demonstrate that an all-optical ultrasound transducer,through which light guided by optical fibers is used to generate and receive ultrasound,is suitable for real-time invasive medical imaging in vivo.Broad-bandwidth ultrasound generation was achieved through the photoacoustic excitation of a multiwalled carbon nanotube-polydimethylsiloxane composite coating on the distal end of a 300-μm multi-mode optical fiber by a pulsed laser.The interrogation of a high-finesse Fabry–Pérot cavity on a single-mode optical fiber by a wavelength-tunable continuous-wave laser was applied for ultrasound reception.This transducer was integrated within a custom inner transseptal needle(diameter 1.08 mm;length 78 cm)that included a metallic septum to acoustically isolate the two optical fibers.The use of this needle within the beating heart of a pig provided unprecedented realtime views(50 Hz scan rate)of cardiac tissue(depth:2.5 cm;axial resolution:64μm)and revealed the critical anatomical structures required to safely perform a transseptal crossing:the right and left atrial walls,the right atrial appendage,and the limbus fossae ovalis.This new paradigm will allow ultrasound imaging to be integrated into a broad range of minimally invasive devices in different clinical contexts.Malcolm C Finlay Charles A Mosse Richard J Colchester Sacha Noimark Edward Z Zhang Sebastien Ourselin Paul C Beard Richard J Schilling Ivan P Parkin Ioannis Papakonstantinou Adrien E Desjardins 2017Light(Science & Applications)2017,6,1:6
2Sclerostin activity plays a key role in the negative effect of glucocorticoid signaling on osteoblast function in mice显示文摘Stress during prenatal development is correlated with detrimental cognitive and behavioral outcomes in offspring. However, the long-term impact of prenatal stress(PS) and disrupted glucocorticoid signaling on bone mass and strength is not understood. In contrast, the detrimental effect of lead(Pb) on skeletal health is well documented. As stress and Pb act on common biological targets via glucocorticoid signaling pathways and co-occur in the environment, this study first sought to assess the combined effect of stress and Pb on bone quality in association with alterations in glucocorticoid signaling. Bone parameters were evaluated using microCT, histomorphometry, and strength determination in 8-month-old male mouse offspring subjected to PS on gestational days 16 and 17, lifetime Pb exposure(100 p.p.m. Pb in drinking water), or to both. Pb reduced trabecular bone mass and, when combined with PS, Pb unmasked an exaggerated decrement in bone mass and tensile strength. Next, to characterize a mechanism of glucocorticoid effect on bone, prednisolone was implanted subcutaneously(controlled-release pellet, 5 mg·kg^(-1) per day) in 5-month-old mice that decreased osteoblastic activity and increased sclerostin and leptin levels. Furthermore, the synthetic glucocorticoid dexamethasone alters the anabolic Wnt signaling pathway. The Wnt pathway inhibitor sclerostin has several glucocorticoid response elements, and dexamethasone administration to osteoblastic cells induces sclerostin expression. Dexamethasone treatment of isolated bone marrow cells decreased bone nodule formation, whereas removal of sclerostin protected against this decrement in mineralization.Collectively, these findings suggest that bone loss associated with steroid-induced osteoporosis is a consequence of sclerostin-mediated restriction of Wnt signaling, which may mechanistically facilitate glucocorticoid toxicity in bone.Eric E Beier Tzong-Jen Sheu Emily A Resseguie Masahiko Takahata Hani A Awad Deborah A Cory-Slechta J Edward Puzas 2017Bone Research2017,5,2:3
3Stratification of outcomes for mucinous appendiceal adenocarcinoma with peritoneal metastasis by histological grade显示文摘AIM To investigate the importance of a three-tiered histologic grade on outcomes for patients with mucinous appendiceal adenocarcinoma(MAA).METHODS Two hundred and sixty-five patients with MAA undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were identified from a prospective database from 2004 through 2014. All pathology was reviewed by our gastrointestinal subspecialty pathologists and histological grade was classified as well-differentiated, moderately differentiated, and poorly differentiated. Survival analysis was performed using Cox proportional hazards regression.RESULTS There were 201(75.8%) well-, 45(16.9%) moderatelyand 19(7.2%) poorly-differentiated tumors. Histological grade significantly stratified the 5-year overall survival(OS), 94%, 71% and 30% respectively(P < 0.001) as well as the 5-year disease-free survival(DFS) 66%, 21% and 0%, respectively(P < 0.001). Independent predictors of DFS included tumor grade(HR = 1.78, 95%CI: 1.21-2.63, P = 0.008), lymph node involvement(HR = 0.33, 95%CI: 0.11-0.98, P < 0.02), previous surgical score(HR = 1.31, 95%CI: 1.1-1.65, P = 0.03) and peritoneal carcinomatosis index(PCI)(HR = 1.05, 95%CI: 1.02-1.08, P = 0.002). Independent predictors of OS include tumor grade(HR = 2.79, 95%CI: 1.26-6.21, P = 0.01), PCI(HR = 1.10, 95%CI: 1.03-1.16, P = 0.002), and complete cytoreduction(HR = 0.32, 95%CI: 0.11-0.92, P = 0.03). Tumor grade and PCI were the only independent predictors of both DFS and OS. Furthermore, histological grade and lymphovascular invasion stratified the risk of lymph node metastasis into a low(6%) and high(40%) risk groups. CONCLUSION Our data demonstrates that moderately differentiated MAA have a clinical behavior and outcome that is distinct from well-and poorly-differentiated MAA. The threetier grade classification provides improved prognostic stratification and should be incorporated into patient selection and treatment algorithms.Travis Edward Grotz Richard E Royal Paul F Mansfield Michael James Overman Gary N Mann Kristen Ashlee Robinson Karen A Beaty Safiea Rafeeq Auerlio Matamoros Michelle W Taggart Keith Francis Fournier 2017World Journal of Gastrointestinal Oncology2017,9,9:2
