1Management of borderline and locally advanced pancreatic cancer:Where do we stand?显示文摘Many patients with pancreas cancer present with locally advanced pancreatic cancer(LAPC).The principle tools used for diagnosis and staging of LAPC include endoscopic ultrasound,axial imaging with computed tomography and magnetic resonance imaging,and diagnostic laparoscopy.The definition of resectability has historically been vague,as there is considerable debate and controversy as to the definition of LAPC.For the patient with LAPC,there is some level of involvement of the surrounding vascular structures,which include the superior mesenteric artery,celiac axis,hepatic artery,superior mesenteric vein,or portal vein.When feasible,most surgeons would recommend possible surgical resection for patients with borderline LAPC,with the goal of an R0 resection.For initially unresectable LAPC,neoadjuvant should be strongly considered.Specifically,these patients should be offered neoadjuvant therapy,and the tumor should be assessed for possible response and eventual resection.The efficacy of neoadjuvant therapy with this approach as a bridge to potential curative resection is broad,ranging from 3%-79%.The different modalities of neoadjuvant therapy include sin-gle or multi-agent chemotherapy combined with radiation,chemotherapy alone,and chemotherapy followed by chemotherapy with radiation.This review focuses on patients with LAPC and addresses recent advances and controversies in the field.Jin He Andrew J Page Matthew Weiss Christopher L Wolfgang Joseph M Herman Timothy M Pawlik 2014World Journal of Gastroenterology2014,20,9:11
2煤灰沉积的传热过程模型及其数值研究显示文摘计算流体力学(CFD)方法的应用在锅炉设计或燃烧设备的改造过程中有着十分重要的作用.本文研究了实际燃烧过程中普遍存在的煤灰沉积现象对数值计算结果的影响,提出了描述煤灰沉积的新型传热模型,比较了新模型采用前后数值计算结果与实测数据的差异,从而验证了该模型的合理性,提高了对炉内积灰、结渣过程数值描述的精度.徐明厚 郑楚光 HE X G AZEVEDO J L T CARVALHO M G 2002工程热物理学报2002,23,1:10

5Rho/Rock signal transduction pathway is required for MSC tenogenic differentiation显示文摘Mesenchymal stem cell(MSC)-based treatments have shown promise for improving tendon healing and repair.MSCs have the potential to differentiate into multiple lineages in response to select chemical and physical stimuli, including into tenocytes. Cell elongation and cytoskeletal tension have been shown to be instrumental to the process of MSC differentiation. Previous studies have shown that inhibition of stress fiber formation leads MSCs to default toward an adipogenic lineage, which suggests that stress fibers are required for MSCs to sense the environmental factors that can induce differentiation into tenocytes. As the Rho/ROCK signal transduction pathway plays a critical role in both stress fiber formation and in cell sensation, we examined whether the activation of this pathway was required when inducing MSC tendon differentiation using rope-like silk scaffolds. To accomplish this, we employed a loss-of-function approach by knocking out ROCK,actin and myosin(two other components of the pathway) using the specific inhibitors Y-27632, Latrunculin A and blebbistatin, respectively. We demonstrated that independently disrupting the cytoskeleton and the Rho/ROCK pathway abolished the expression of tendon differentiation markers and led to a loss of spindle morphology. Together, these studies suggest that the tension that is generated by MSC elongation is essential for MSC teno-differentiation and that the Rho/ROCK pathway is a critical mediator of tendon differentiation on rope-like silk scaffolds.Edward Maharam Miguel Yaport Nathaniel L Villanueva Takintope Akinyibi Damien Laudier Zhiyong He Daniel J Leong Hui B Sun 2015Bone Research2015,3,3:4
