Effect of Older Age on Postoperative Urinary Retention After Prolapse Surgery.

Importance: Postoperative urinary retention (POUR) is common after reconstructive pelvic surgery. Little is known about the relationship between older age (≥70 years) and POUR after pelvic organ prolapse surgery.

Objectives: We aimed to investigate the relationship between age ≥70 years and POUR.

Hierarchical structures of surface-accessible plasmonic gold and silver nanoparticles for SERS detection.

Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive analytical technique with excellent molecular specificity. However, separate pristine nanoparticles produce relatively weak Raman signals. It is necessary to focus on increasing the "hot-spot" density generated at the nanogaps between the adjacent nanoparticles (second-generation SERS hotspot), thus significantly boosting the Raman signal by creating an electromagnetic field.

Electrically Active Biomaterials for Stimulation and Regeneration in Tissue Engineering.

In the human body, bioelectric cues are crucial for tissue stimulation and regeneration. Electrical stimulation (ES) significantly enhances the regeneration of nerves, bones, cardiovascular tissues, and wounds. However, the use of conventional devices with stimulating metal electrodes is invasive and requires external batteries.

Hierarchical skin lesion image classification with prototypical decision tree.

Traditional disease classification models often disregard the clinical significance of misclassifications and lack interpretability. To overcome these challenges, we propose a hierarchical prototypical decision tree (HPDT) for skin lesion classification. HPDT combines prototypical networks and decision trees, leveraging a class hierarchy to guide interpretable predictions from general to specific categories.
