Diffscs: improving strict cold start recommendation with diffusion model

open access: yesComplex & Intelligent Systems
Strict cold start recommendation poses a significant challenge to recommender systems. It results in traditional collaborative filtering methods being ineffective due to limited or no historical interactions available to new users/items.

Low‐Density Lipoprotein Receptor‐Targeted Biomimetic Nanoplatform Suppresses Glioblastoma Stemness and Remodels Antitumor Immunity via Dual Metabolic Disruption

open access: yesAdvanced Science, EarlyView.
A low‐density lipoprotein receptor‐oriented biomimetic nanoplatform couples brain‐tumor delivery with a mechanistically matched regorafenib‐erythrodiol combination. Concurrent disruption of autophagic nutrient salvage and cholesterol homeostasis collapses bioenergetic and signaling support, suppresses glioblastoma stemness, and promotes immunogenic ...

Cross-Modal Content Inference and Feature Enrichment for Cold-Start Recommendation

open access: yes, 2023
Multimedia recommendation aims to fuse the multi-modal information of items for feature enrichment to improve the recommendation performance. However, existing methods typically introduce multi-modal information based on collaborative information to ...

A Living Multi‐Omics PDX Biobank of High‐Risk Sarcomas Reveals ecDNA‐Driven Oncogene Amplification in Osteosarcoma and Enables Preclinical Precision Oncology

open access: yesAdvanced Science, EarlyView.
A living multi‐omics sarcoma PDX biobank is enriched for high‐risk disease and preserves key patient tumor features at histopathological and molecular levels. Integrated profiling reveals ecDNA‐driven oncogene amplification in osteosarcoma and preferential retention of ecDNA during PDX evolution.

Graph Reasoning for Explainable Cold Start Recommendation

open access: yesCoRR
The cold start problem, where new users or items have no interaction history, remains a critical challenge in recommender systems (RS). A common solution involves using Knowledge Graphs (KG) to train entity embeddings or Graph Neural Networks (GNNs).

Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

open access: yesAdvanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

open access: yesAdvanced Science, EarlyView.
This study established a one‐step method inducing pro‐spermatogonia‐like (activating SOX17) and oogonia‐like (activating SOX17/TFAP2C) cells from porcine pgEpiSCs with a NANOS3‐tdTomato reporter. EGF activates the core PGC program and supports survival; BMP4 further induces NANOS3 and DDX4 expression; IWR1 enhances PGCLC efficiency by suppressing ...

Fc‐Dependent Targeting of the GAS6–MERTK Axis With Monoclonal and Bispecific Antibodies Overcomes Drug Resistance Across EGFR Mutations in Exons 19, 20, and 21

open access: yesAdvanced Science, EarlyView.
EGFR mutations drive a substantial fraction of non‐small cell lung cancers (NSCLC) and are effectively targeted by tyrosine kinase inhibitors (TKIs), including osimertinib. However, resistance inevitably develops through secondary mutations and compensatory receptor activation, including the GAS6 receptor MERTK.

Loss of Intestinal MSTN Promotes GLP‐1 Secretion Through SGLT1 Palmitoylation

open access: yesAdvanced Science, EarlyView.
Intestinal MSTN deficiency enhances glucose‐stimulated GLP‐1 secretion and glucose tolerance in high‐fat diet‐fed mice. Mechanistically, loss of MSTN promotes YY1‐associated ZDHHC20 expression, increasing SGLT1 S‐palmitoylation at Cys301 and its plasma membrane localization in L cells.
