The biomedical properties of a porous bio-collagenic polymer extracted from leather industrial waste residues have been investigated in wound healing and tissue regeneration in induced wounds in rats. Application of the pure undiluted bio-collagen to induced wounds in rats dramatically improved its healing after 7 days in terms of collagen production and wound filling as well as in the migration and differentiation of keratinocytes. The formulation tested was found to be three times more effective than the commercial reference product Catrix (Heal Progress (HP): 8 ± 1.55 2.33 ± 0.52, < 0.001; Formation of Collagen (FC): 7.5 ± 1.05 2.17 ± 0.75, < 0.001; Regeneration of Epidermis (RE): 13.33 ± 5.11 5 ± 5.48, < 0.05).

Background: Kidney tumors, common in the urinary system, have widely varying survival rates post-surgery. Current prognostic methods rely on invasive biopsies, highlighting the need for non-invasive, accurate prediction models to assist in clinical decision-making.
Purpose: This study aimed to construct a K-means clustering algorithm enhanced by Transformer-based feature transformation to predict the overall survival rate of patients after kidney tumor resection and provide an interpretability analysis of the model to assist in clinical decision-making.

Purpose: Tibial open shaft fractures are very common and susceptible to infection, which can lead to significant morbidity especially infection and non-union. Antibiotic coated nail is one option for fixing open shaft tibial fractures to minimise infection. This study aimed to compare the clinical outcome of Gentamicin-coated tibial nails versus regular unreamed interlocking tibial nails in the treatment of type I and II tibial open fractures.

Dissecting the spatial heterogeneity of cancer-associated fibroblasts (CAFs) is vital for understanding tumor biology and therapeutic design. By combining pathological image analysis with spatial proteomics, we revealed two stromal archetypes in hepatocellular carcinoma (HCC) with different biological functions and extracellular matrix compositions. Using paired single-cell RNA and epigenomic sequencing with Stereo-seq, we revealed two fibroblast subsets CAF-FAP and CAF-C7, whose spatial enrichment strongly correlated with the two stromal archetypes and opposing patient prognosis.

Uncontrollable bleeding poses a significant risk of death and cost in wars, vehicle accidents, and first aid. Hence, in order to seal uncontrollable bleeding and promote wound healing, the Fe-driven chitosan quaternary ammonium salt self-gelling powder (QPF) was prepared using 5%QCS/AA/Fe with the 52.72 % ± 0.
