Aging is associated with disrupted sleep patterns, such as fragmented sleep and reduced efficiency, leading to negative health outcomes. There is evidence of a bidirectional relationship between sleep and gut microbiota, which plays a key role in the gut-brain axis and overall health. However, studies on this relationship in older adults have limited generalizability and show conflicting results, highlighting the need for further research.

January 2025

Institute of Pharmaceutical Science, Faculty of Life Sciences and Medicine, King's College London, Franklin-Wilkins Building, 150 Stamford Street, London, SE1 9NH, UK.

Immune checkpoint (ICP) blockade has shown limited effectiveness in glioblastoma (GBM), particularly in the mesenchymal subtype, where interactions between immune cells and glioblastoma cancer stem cells (GSCs) drive immunosuppression and therapy resistance. Tailoring ICPs specific to GSCs can enhance the antitumor immune response. This study proposes the use of lipid nanoparticles (LNPs) encapsulating CRISPR RNAs as an in vivo screening tool for ICPs in a syngeneic model of mesenchymal GSCs.

The advent of biomacromolecules antagonizing vascular endothelial growth factor (VEGF) has revolutionized the treatment of neovascular age-related macular degeneration (nAMD). However, frequent intravitreal injections of these biomacromolecules impose an enormous burden on patients and create a massive workload for healthcare providers. This causes patients to abandon therapy, ultimately leading to progressive and irreversible vision loss.

Lewis and Brønsted Acids Synergy in Photocatalytic Aerobic Alcohol Oxidations.

Angew Chem Int Ed Engl

January 2025

Fuzhou University, Chemistry, 523 Gongye Rd, Gulou, 350000, Fuzhou, CHINA.

Photocatalytic chemical transformations for green organic synthesis has attracted much interest. However, their development is greatly hampered by the lack of sufficient reactive sites on the photocatalyst surface for the adsorption and activation of substrate molecules. Herein, we demonstrate that the introduction of well-defined Lewis and Brønsted acid sites coexisting on the surface of TiO2 (SO42-/N-TiO2) creates abundant active adsorption sites for photoredox reactions.

The globally prevalent rotator cuff tear has a high re-rupture rate, attributing to the failure to reproduce the interfacial fibrocartilaginous enthesis. Herein, a hierarchically organized membrane is developed that mimics the heterogeneous anatomy and properties of the natural enthesis and finely facilitates the reconstruction of tendon-bone interface. A biphasic membrane consisting of a microporous layer and a mineralized fibrous layer is constructed through the non-solvent induced phase separation (NIPS) strategy followed by a co-axial electrospinning procedure.

Design, Synthesis and Application of Chiral Spirocyclic Bisindoles.

Angew Chem Int Ed Engl

January 2025

Hong Kong University of Science and Technology, Department of Chemistry, Clear Water Bay, Hong Kong, HONG KONG.

While modifications of the privileged catalyst backbones, such as 1,1'-spirobiindane-7,7'-diol (SPINOL), have led to the development of diverse useful chiral catalysts, the incorporation of heteroarenes in such chiral spirocyclic structures has limitedly known. Herein we report the design of a type of chiral spirocyclic bisindole skeletons where the electronically distinct heteroarenes serve as direct anchor for functional sites. Separate approaches for the synthesis of two different families of such skeletons have been developed via chiral phosphoric acid and rhodium catalysis, respectively.

Introduction: Alzheimer's disease (AD) is a progressive neurodegenerative disease and the leading cause of dementia. Recent research highlights meningeal lymphatics as key regulators in neurological diseases, suggesting that enhancing their drainage function could be a potential therapeutic strategy for AD. Our proof-of-concept study demonstrated that cranial bone transport can improve meningeal lymphatic drainage function and promote ischemic stroke recovery.

Transition metal oxide electrocatalysts (TMOEs) are poised to revive grid-scale all-vanadium redox flow batteries (VRFBs) due to their low-cost and unique electronic properties, while often inescapably harboring surface vacancies. The role of local vacancy-induced physicochemical properties on vanadium-redox electrochemistry (VRE), encompassing kinetics, and stability, remains profoundly unveiled. Herein, for the first time, it is revealed that vacancies induce atomic-scale polarization in TMOEs and elucidate its mechanism in VRE.

Omnidirectional strain sensing and direction recognition ability are features of the human tactile sense, essential to address the intricate and dynamic requirements of real-world applications. Most of the current strain sensors work by converting uniaxial strain into electrical signals, which restricts their use in environments with multiaxial strain. Here, the first device with simultaneous isotropic omnidirectional hypersensitive strain sensing and direction recognition (IOHSDR) capabilities is introduced.

Sepsis-induced immunosuppression is related to increased susceptibility to secondary infections and death. Lung is the most vulnerable target organ in sepsis, but the understanding of the pulmonary immunosuppression state is still limited. Here, single-cell RNA sequencing of bronchoalveolar lavage fluid (BALF) is performed to map the landscape of immune cells, revealing a neutrophil-driven immunosuppressive program in the lungs of patients with immunosuppressive sepsis.

Spin light-emitting diodes (spin-LEDs) are important for spin-based electronic circuits as they convert the carrier spin information to optical polarization. Recently, chiral-induced spin selectivity (CISS) has emerged as a new paradigm to enable spin-LED as it does not require any magnetic components and operates at room temperature. However, CISS-enabled spin-LED with tunable wavelengths ranging from red to near-infrared (NIR) has yet to be demonstrated.
