In this study, we investigated whether the metabolic alteration of cancer-associated fibroblasts (CAFs) occurs via miR-21 remodeling and the effect of this alteration on pancreatic cancer cells. CAFs and normal fibroblasts (NFs) were isolated and cultured. Glucose consumption and lactic acid production were tested, and lactate dehydrogenase (LDHA), pyruvate kinase m2 (PKM2), and miR-21 expressi...

wettability alteration is an important method for increasing oil recovery from oil-wet carbonatereservoirs. chemical agents like surfactants are known as wettability modifiers in carbonate systems.oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wetto water-wet condition with adding dilute surfactant and electrolyte solutions. this paper invest...

One of the most important characteristics of annular arrays is their superior focal capabilities. In order to achieve the desired focussing, each of the elements is fired in different times. The delay times used for beam focussing are called focal laws. The focal laws are automatically calculated from the inspection software. In order to make sure that the focal laws are calculated correctly fr...

Modern production of structural parts in the aeronautic industry is characterized by mechanically optimized structures that can be complicated to inspect due to complex geometries and/or complex materials. Developing NDT procedures is thus more challenging and could become costly without tools to help NDT design and performance predictions. Simulation is a major asset to help engineers to evalu...

Traditional online wheel-set ultrasonic inspection method and inspection technology can not meet the new requirement of High Power Locomotive wheel-set online. In this article, features of locomotive wheel and defect distribution are analyzed, and a more strictly online inspection requirement is put forward. Based on which, an optimized multi arrangement of phased array and conventional ultraso...

The effect of alteration on the geochemistry and mechanical properties granite from Pingjiang, Hunan Province, China was investigated. Six weathered 14 hydrothermally altered samples in 3 adits were collected for strength tests, mineralogical geochemical analysis. types observed within chloritization argillization. Samples taken a silicified fracture zone enriched quartz. Weathering to signific...
