Triggered Calcium Lightning Programs Cochlear Development

open access: yesExploration, EarlyView.
Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...

Acupuncture Alleviates Allergic Rhinitis by Activating the AMPK/PGC‐1α Pathway to Attenuate Mitochondrial Oxidative Stress and Restore Epithelial Barrier Function

open access: yesFlavour and Fragrance Journal, EarlyView.
Acupuncture at Feishu (BL13), Shenshu (BL23), Yingxiang (LI20), and Dazhui (GV14) alleviates allergic rhinitis by activating the AMPK/PGC‐1α/NRF1/TFAM signalling axis. This activation improves mitochondrial biogenesis and function, reduces mtROS‐mediated oxidative stress, restores ATP production and respiratory complex I/IV activity, suppresses IgE and

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

open access: yesFood Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

open access: yesGeological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Tofacitinib Regulates β‐Catenin Nuclear Translocation to Inhibit FLS Migration and Alleviate Clinical Symptoms of RA

open access: yesiNew Medicine, EarlyView.
ABSTRACT Objective Tofacitinib is a Janus kinase (JAK) inhibitor approved for the treatment of moderate‐to‐severe rheumatoid arthritis (RA). However, its synovium‐related molecular mechanisms, particularly its regulatory effect on fibroblast‐like synoviocyte (FLS) migration, remain incompletely understood.

MRI Proton Density Fat Fraction as a Biomarker of Marrow Recovery Following Organ‐Sparing Total Marrow Irradiation in Sickle Cell Disease

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive quantitative assessment of marrow recovery after curative therapies such as total marrow irradiation (TMI) and bone marrow transplantation (BMT) remain poorly defined, particularly in sickle cell disease (SCD). Purpose To evaluate MRI‐derived proton density fat fraction (PDFF) as a biomarker of marrow recovery following ...

Dasatinib and quercetin prevent alveolar bone loss in aged mice

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.
