The progression rate and risk factor analysis of small gastric subepithelial tumors: a systematic review and meta-analysis.

Background And Aims: Small gastric subepithelial tumors (SETs) in the stomach can be managed through surveillance or resection. However, it is still controversial how often the lesion would progress if left untreated. This study aimed to evaluate the progression rate of small SETs and identify risk factors influencing tumor growth.

Soft Metalens for Broadband Ultrasonic Focusing through Aberration Layers.

Aberration layers (AL) often present significant energy transmission barriers in microwave engineering, electromagnetic waves, and medical ultrasound. However, achieving broadband ultrasonic focusing through aberration layers like the human skull using conventional materials such as metals and elastomers has proven challenging. In this study, we introduce an inverse phase encoding method employing tunable soft metalens to penetrate heterogeneous aberration layers.

College students' disciplinary expertise and their entrepreneurial intentions: an exploratory study based on foreign language majors with experience in innovation and entrepreneurship training programs.

Taking foreign language majors with experience in innovation and entrepreneurship training program (IETP) as samples, this study investigates the influence of disciplinary expertise on entrepreneurial intention. Based on the theory of planned behavior (TPB), a model was designed to examine the relationships among entrepreneurial intentions, perceived behavioral control, attitude toward entrepreneurship, subjective norms, IETP experience, foreign language self-efficacy and cultural intelligence. The data were collected through questionnaires and Partial least squares structural equation modeling (PLS-SEM) was adopted to test the hypotheses.

Noncovalently Bridging Cell-Surface Proteins Using Synthetic Peptides to Modulate Cell Apoptosis.

Controlled high-order clustering of cell-surface proteins is an essential but unmatched regulatory mechanism in living systems for the modulation of cell behavior. Here, we present a strategy for generating extended and tunable one-dimensional clusters of death receptors on live cell surfaces by employing synthetic peptides to noncovalently bridging the proteins. The on-cell assembly process is validated through super-resolution fluorescence imaging and fluorescence lifetime imaging analyses.

Texture Analysis of Fibrous Meningioma Using Label-Free Multiphoton Microscopy.

Fibrous meningiomas, a common type of brain tumor, present surgical challenges due to their variable hardness, which is crucial for complete resection and patient prognosis. This study explores the use of label-free multiphoton microscopy (MPM) for the objective assessment of the texture of fibrous meningiomas. Fresh tumor samples from 20 patients were analyzed using both multichannel and lambda mode MPM, with quantitative image analysis algorithms determining collagen content and multi-peak spectral fitting providing additional optical collagen metrics.
