Testosterone Delays Bone Microstructural Destruction via Osteoblast‐Androgen Receptor‐Mediated Upregulation of Tenascin‐C

Advanced Science, EarlyView.
This study reveals that Testosterone–Androgen Receptor signaling delays elderly male bone destruction by upregulation of the osteoblastic extracellular tenascin‐C (TNC). The osteoprotective effect of fibrinogen C‐terminus of TNC is demonstrated in male osteoporotic mice model that osteoblast‐specific Ar‐knockout, potentially via inhibition of ...

Long Term High‐Salt Diet Induces Cognitive Impairments via Down‐Regulating SHANK1

Advanced Science, EarlyView.
The study identifies a novel mechanistic link between long‐term HS diet and cognitive impairment, wherein PKA/CREB axis inactivation leads to SHANK1 reduction, synaptic damage, and cognitive deficits. Abstract High‐salt (HS) diet is an established risk factor for cognitive impairment, but the underlying mechanisms remain unclear.

Assessment of Toluidine Blue in Oral Leukoplakia [PDF]

, 2011
Squamous cell carcinoma is the most common cancer of the oral cavity and the prognosis of the tumor depends on the early detection of the carcinoma. Toluidine blue is a metachromatic die of the thiazine group that has been effectively used as a nuclear ...

Identification of Schwann Cells in Human Intracranial Arteries: Potential Regulatory Role in Atherosclerotic Plaque Progression

Advanced Science, EarlyView.
Schwann cells may facilitate intracranial plaque progression via neurovascular remodelingcting with vascular smooth muscle cells in atherosclerotic plaques, with the SPP1 ‐ ITGB1 signaling axis mediating this interaction as a novel mechanism. Abstract Intracranial atherosclerosis (ICAS), a common cause of ischemic stroke, remains a therapeutic ...

Gas Bubbles from Biodegradable Magnesium Implants Convey Mechanical Cues and Promote Immune Cell Stimulation

Advanced Science, EarlyView.
Bubbles in soft tissue are the unavoidable consequence of magnesium implant degradation in patients, yet their biological significance remains unclear. Using advanced imaging and spatial transcriptomics, this study reveals a pronounced inflammatory and mechanical response near bubbles, contrasting with pro‐regenerative events closer to the implant ...
