From structure to therapy: the critical influence of cartilaginous endplates and microvascular network on intervertebral disc degeneration.

The intervertebral disc (IVD) is the largest avascular structure in the human body. The cartilaginous endplate (CEP) is a layer of translucent cartilage located at the upper and lower edges of the vertebral bodies. On one hand, CEPs endure pressure from within the IVD and the tensile and shear forces of the annulus fibrosus, promoting uniform distribution of compressive loads on the vertebral bodies.

Unveiling the Gut-Disc Axis: How Microbiome Dysbiosis Accelerates Intervertebral Disc Degeneration.

The gut microbiome (GM), often referred to as the second genome of the human body, plays a crucial role in various metabolic processes and mediates the development of numerous diseases. Intervertebral disc degeneration (IDD) is an age-related degenerative spinal disease characterized by the loss of disc height, hydration, and integrity, leading to pain and reduced mobility. Although the pathogenesis of IDD is not fully understood, recent studies suggest that dysbiosis of the gut microbiome may accelerate the progression of IDD through multiple mechanisms.

Formononetin alleviates thermal injury-induced skin fibroblast apoptosis and promotes cell proliferation and migration.

The aim of this study was to explore the effect and mechanism of formononetin (FMNT) in thermal-injured fibroblast proliferation, apoptosis, and oxidative stress. After thermal injury, human skin fibroblast (HSF) cells showed inhibited proliferation, migration, extracellular matrix (ECM) synthesis; and increased apoptosis, reactive oxygen species (ROS) production, and inflammation. Specifically, after thermal injury, cell viability, migration distance, and protein levels of collagen I, collagen III, α-SMA, MMP1, and MMP3 were reduced; cell apoptosis rate and TUNEL-positive cell numbers were increased; the levels of Bax and cleaved caspase-3 were elevated, while Bcl-2 level was reduced.

The correlation of acupuncture and moxibustion points for the treatment of diminished ovarian reserve and premature ovarian failure: A systematic review based on complex network.

Background: Infertility rates have risen in recent years, with diminished ovarian reserve (DOR) affecting 10% of infertile women, accounting for approximately 20% of ovarian disorders. This highlights the importance of exploring effective treatments for DOR. This study investigates acupoint compatibility rules in acupuncture and moxibustion therapies for DOR and premature ovarian failure (POF) using complex network analysis.

Mechanisms of fibrinogen trans-activation of the EGFR/Ca2+ signaling axis to regulate mitochondrial transport and energy transfer and inhibit axonal regeneration following cerebral ischemia.

Ischemic stroke results in inhibition of axonal regeneration but the roles of fibrinogen (Fg) in neuronal signaling and energy crises in experimental stroke are under-investigated. We explored the mechanism of Fg modulation of axonal regeneration and neuronal energy crisis after cerebral ischemia using a permanent middle cerebral artery occlusion (MCAO) rat model and primary cortical neurons under low glucose-low oxygen. Behavioral tests assessed neurological deficits; immunofluorescence, immunohistochemistry, and Western-blot analyzed Fg and protein levels.

Integrated machine learning and Mendelian randomization reveal PALMD as a prognostic biomarker for nonspecific orbital inflammation.

Background: Nonspecific Orbital Inflammation (NSOI) remains a perplexing enigma among proliferative inflammatory disorders. Its etiology is idiopathic, characterized by distinctive and polymorphous lymphoid infiltration within the orbital region. Preliminary investigations suggest that PALMD localizes within the cytosol, potentially playing a crucial role in cellular processes, including plasma membrane dynamics and myogenic differentiation.
