SSATNet: Spectral-spatial attention transformer for hyperspectral corn image classification.
Front Plant Sci
January 2025
School of Information Engineering, Henan Institute of Science and Technology, Xinxiang, China.
Hyperspectral images are rich in spectral and spatial information, providing a detailed and comprehensive description of objects, which makes hyperspectral image analysis technology essential in intelligent agriculture. With various corn seed varieties exhibiting significant internal structural differences, accurate classification is crucial for planting, monitoring, and consumption. However, due to the large volume and complex features of hyperspectral corn image data, existing methods often fall short in feature extraction and utilization, leading to low classification accuracy.

Department of Biotherapy, Cancer Center, West China Hospital, Sichuan University, Chengdu, China.
Objective: To investigate the optimal cut-off value of immunohistochemical marker Ki67 as a prognostic factor to predict the recurrence of non-muscle invasive bladder urothelial carcinoma (NMIBUC).
Methods: A total of 331 patients diagnosed with NMIBUC who underwent surgery in the Yongchuan Hospital and the Second Affiliated Hospital of Chongqing Medical University from January 2012 to January 2020 were finally included in this study. The optimal cut-off value of Ki67 for predicting recurrence of NMIBUC was calculated by ROC curve and Youden index.
Semi-quantitative scoring criteria based on multiple staining methods combined with machine learning to evaluate residual nuclei in decellularized matrix.

National Engineering Research Center for Biomaterials, Sichuan University, Chengdu, Sichuan 610064, China.
The detection of residual nuclei in decellularized extracellular matrix (dECM) biomaterials is critical for ensuring their quality and biocompatibility. However, current evaluation methods have limitations in addressing impurity interference and providing intelligent analysis. In this study, we utilized four staining techniques-hematoxylin-eosin staining, acetocarmine staining, the Feulgen reaction and 4',6-diamidino-2-phenylindole staining-to detect residual nuclei in dECM biomaterials.

Alcohol-associated liver disease (ALD) poses a significant global health burden and is a leading cause of liver-related morbidity and mortality. ALD encompasses a spectrum of disease states ranging from asymptomatic steatosis to acute hepatitis and cirrhosis. Alcohol use disorder (AUD) significantly increases the risk of developing ALD, and insight into AUD can provide a more complete understanding of ALD and the patients affected by these interrelated diseases.

JACC Adv
February 2025
Division of Cardiology, Atlantic Health, New Jersey, USA.
Background: The Valsalva maneuver is essential in evaluating left ventricular outflow tract (LVOT) obstruction in patients with hypertrophic cardiomyopathy (HCM). Traditionally, a self-directed Valsalva (SDV) maneuver is taught to patients using vague instructions such as "bear down." SDV is often not performed correctly leading to variable results and underestimation of the true provocable LVOT gradient.
