18 F-FDG PET/CT may sometimes not be an ideal imaging method for gastric adenocarcinoma. Because of the unstable physiological uptake of 18 F-FDG in the gastrointestinal tract and muscles, it may interfere with the detection of lesions. We present a case of gastric intramucosal adenocarcinoma detected by 68 Ga-FAPI PET/CT in a patient with nasopharyngeal carcinoma.

- * The success of this technology hinges on the mold quality, which can significantly impact the final printed patterns.
- * A new fabrication technique for creating sub-100 nm silicon nano-molds has been studied, resulting in minimal variations in width (4%) and depth (2%) across a large silicon wafer, indicating potential for scalable, precise manufacturing of nano devices.
The performance of an asphalt mixture will deteriorate under the condition of salt erosion, but there are different opinions on the mechanism of deterioration. Few studies have focused on the relation between the change of void characteristics and performance deterioration of an asphalt mixture exposed to salt erosion. To explore the relation between the air voids characteristics of an asphalt mixture and mechanical damage under salt erosion, the mechanical damage in an asphalt mixture was measured by splitting strength.

In this paper, a novel alignment method is presented, which employs data processing of the two-dimensional power spectral density (2D-PSD) for a near-field image and resolves the beam pointing error relative to the spatial filter pinhole directly. Combining this with a near-field fiducial mark, the operation of beam alignment is achieved.

Objective: To study the inhibition effect of survivin antisense RNA on the growth of ovarian carcinoma SKOV3 cells, and the tumorigenic ability of the transfected SKOV3 cells implanted subcutaneously in nude mice.
Methods: The recombinant vector pcDNA3-SVVas was constructed by directed cloning of fragments of survivin cDNA into the vector. The ovarian carcinoma SKOV3 cells were transfected with pcDNA3-SVVas by lipofectamine 2000 (SKOV3/SVVas cells), and blank vector pcDNA3 as control (SKOV3/neo cells).
