Enhancing Recommender Systems through Imputation and Social-Aware Graph Convolutional Neural Network.

Recommendation systems are vital tools for helping users discover content that suits their interests. Collaborative filtering methods are one of the techniques employed for analyzing interactions between users and items, which are typically stored in a sparse matrix. This inherent sparsity poses a challenge because it necessitates accurately and effectively filling in these gaps to provide users with meaningful and personalized recommendations.

Non-coding RNAs and regulation of the PI3K signaling pathway in lung cancer: Recent insights and potential clinical applications.

Lung cancer (LC) is one of the most common causes of cancer-related death worldwide. It has been demonstrated that the prognosis of current drug treatments is affected by a variety of factors, including late stage, tumor recurrence, inaccessibility to appropriate treatments, and, most importantly, chemotherapy resistance. Non-coding RNAs (ncRNAs) contribute to tumor development, with some acting as tumor suppressors and others as oncogenes.

The Extended Corset with Bra Strap: Refinements in the Corset Trunkplasty Technique.

The corset trunkplasty was introduced by Moya et al. in 2009 (Moya and Sharma in JPRAS 62:56-64, 2009). It is a modified abdominoplasty technique that combines vertical and high lateral incisions to achieve an hourglass shape in post-massive weight loss patients.

3-(Sulfamic acid)-propyltriethoxysilane on biochar nanoparticles as a practical, biocompatible, recyclable and chemoselective nanocatalyst in organic reactions.

Recyclable and inexpensive catalysts, waste regeneration, use of available and safe solvents are important principles of green chemistry. Therefore, in this project, biochar nanoparticles (BNPs) were synthesized by the pyrolysis method from chicken manure. Then, 3-(sulfamic acid)-propyltriethoxysilane (SAPES) was immobilized on the surface of BNPs (SAPES@BNPs).

Inferolateral Pectoralis Sling Technique for Augmentation Mastopexy.

Background: Augmentation mastopexy remains a challenging procedure. The goal is to achieve correction of breast ptosis whilst adding implant volume, and avoid complications of premature waterfall deformity, bottoming out and further revision surgery, particularly when using smooth implants. We aim to describe and evaluate a technique to reduce implant malposition in augmentation mastopexy.
