The mechanism of tumor budding (TB) in gastric adenocarcinoma (GAC) and its relationship with biological indicators and prognostic significance, remains unclear. In this study, we conducted a comprehensive analysis using whole-slide imaging to evaluate TB in 75 cases of GAC. Our findings revealed the risk factors associated with TB in GAC and their impact on patient prognosis.

Background: Dioscorea polystachya and its closely related species are original plants of the tuber crop "yam", which had been intensively use for medicinal and food purposes and widely cultivated in northern China and its surrounding areas with a long history. Many cultivars of these species are often confused with one another because of similar tuber morphology, however, conventional DNA barcoding faces practical limitations restricting the method to effectively identify closely related species. In addition, phylogenetic relationships among various cultivar groups of Chinese yam (D.

Background: Structural magnetic resonance imaging (sMRI) can reflect structural abnormalities of the brain. Due to its high tissue contrast and spatial resolution, it is considered as an MRI sequence in diagnostic tasks related to Alzheimer's disease (AD). Thus far, most studies based on sMRI have only focused on pathological changes in disease-related brain regions in Euclidean space, ignoring the association and interaction between brain regions represented in non-Euclidean space.

Article Synopsis
  • * This work extends the Kirkendall effect to allow reversible structural and phase transformations between metal chalcogenides and metal phosphides using NiS/CuS NCs as starting points.
  • * By utilizing ligand-regulated sequential extractions and anion diffusion, the method enables solid-to-hollow-to-solid transformations while maintaining NC morphology, creating versatile reconfigurable NCs with adjustable compositions and structures.

Article Synopsis
  • Engineering electronic band structures through doping is essential for enhancing thermoelectric performance in materials.
  • The study reveals that the Sn-s states in SnTe significantly impact the density of states at the valence band's top, influencing band structure tuning.
  • A design approach is presented, identifying Al as an effective dopant that, combined with Sb and AgBiTe, leads to a record high average ZT of 1.15 across a temperature range of 300 to 873 K.
