Supervised Functional Principal Component Analysis Under the Mixture Cure Rate Model: An Application to Alzheimer'S Disease.

Brain imaging data is one of the primary predictors for assessing the risk of Alzheimer's disease (AD). This study aims to extract image-based features associated with the possibly right-censored time-to-event outcomes and to improve predictive performance. While the functional proportional hazards model is well-studied in the literature, these studies often do not consider the existence of patients who have a very low risk and are approximately insusceptible to AD.

Synthesis of chiral -free sulfinamides by asymmetric condensation of stable sulfinates and ammonium salts.

Herein, we developed a practical approach using stable, cost-effective ammonium salts with an organic base to generate anhydrous ammonia for asymmetric sulfinylation, achieving a broad range of enantioenriched sulfinamides with excellent yields and optical purity. Additionally, these sulfinamide products serve as versatile precursors for S-stereogenic functional molecules with potential in organic synthesis and drug discovery.

Polystyrene Nanoplastics Elicit Multiple Responses in Immune Cells of the (, 1826).

The improper disposal of plastic products/wastes can lead to the release of nanoplastics (NPs) into environmental media, especially soil. Nevertheless, their toxicity mechanisms in soil invertebrates remain unclear. This study investigated the impact of polystyrene NPs on (, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis.

Coordinated regulation of two LacI family regulators, GvmR and GvmR2, on guvermectin production in .

Guvermectin, a purine nucleoside natural product produced by the genus S, has recently been registered as a new biopesticide to boost rice yield. Despite its economic and agricultural significance, the regulatory mechanisms of guvermectin biosynthesis remain essentially unknown, hindering industrial production and widespread agricultural application. Here, we examined the roles of two LacI family regulators, and , located within and adjacent to the guvermectin biosynthesis cluster, respectively, in guvermectin production in NEAU6.

Therapeutic effect of low-dose BMSCs-Loaded 3D microscaffold on early osteonecrosis of the femoral head.

The early treatment of Osteonecrosis of Femoral Head (ONFH) remains a clinical challenge. Conventional Bone Marrow Mesenchymal Stem Cell (BMSC) injection methods often result in unsatisfactory outcomes due to mechanical cell damage, low cell survival and retention rates, inadequate cell matrix accumulation, and poor intercellular interaction. In this study, we employed a novel cell carrier material termed "3D Microscaffold" to deliver BMSCs, addressing these issues and enhancing the therapeutic effects of cell therapy for ONFH.
