A tough soft-hard interface in the human knee joint driven by multiscale toughening mechanisms.

Joining heterogeneous materials in engineered structures remains a significant challenge due to stress concentration at interfaces, which often leads to unexpected failures. Investigating the complex, multiscale-graded structures found in animal tissue provides valuable insights that can help address this challenge. The human meniscus root-bone interface is an exemplary model, renowned for its exceptional fatigue resistance, toughness, and interfacial adhesion properties throughout its lifespan.

Nanomaterials-Induced Pyroptosis: Advancing Novel Therapeutic Pathways in Nanomedicine.

Pyroptosis, a form of programmed cell death characterized by cell lysis and inflammation, has significant implications for disease treatment. Nanomaterials (NMs), with their unique physicochemical properties, can precisely modulate pyroptosis, offering novel and intelligent therapeutic strategies for cancer, infectious diseases, and chronic inflammatory conditions with targeted activation and reduced systemic toxicity. This review explores the mechanisms by which NMs regulate pyroptosis, comparing molecular and NM inducers, and examines the role of intrinsic properties such as size, shape, surface charge, and chemical composition in these processes.

A Study on Dust Storm Pollution and Source Identification in Northwestern China.

In April 2023, a major dust storm event in Lanzhou attracted widespread attention. This study provides a comprehensive analysis of the causes, progression, and dust sources of this event using multiple data sources and methods. Backward trajectory analysis using the HYSPLIT model was employed to trace the origins of the dust, while FY-2H satellite data provided high-resolution dust distribution patterns.

Nano-Oncologic Vaccine for Boosting Cancer Immunotherapy: The Horizons in Cancer Treatment.

Nano-oncologic vaccines represent a groundbreaking approach in the field of cancer immunotherapy, leveraging the unique advantages of nanotechnology to enhance the effectiveness and specificity of cancer treatments. These vaccines utilize nanoscale carriers to deliver tumor-associated antigens and immunostimulatory adjuvants, facilitating targeted immune activation and promoting robust antitumor responses. By improving antigen presentation and localizing immune activation within the tumor microenvironment, nano-oncologic vaccines can significantly increase the efficacy of cancer immunotherapy, particularly when combined with other treatment modalities.

Transcription factor specificity protein (SP) family in renal physiology and diseases.

Dysregulated specificity proteins (SPs), members of the C2H2 zinc-finger family, are crucial transcription factors (TFs) with implications for renal physiology and diseases. This comprehensive review focuses on the role of SP family members, particularly SP1 and SP3, in renal physiology and pathology. A detailed analysis of their expression and cellular localization in the healthy human kidney is presented, highlighting their involvement in fatty acid metabolism, electrolyte regulation, and the synthesis of important molecules.
