Sex-specific ultrasound imaging biomarkers of neurodegeneration in a mouse model.
Front Aging Neurosci
January 2025
Department of Chemistry, Memorial University of Newfoundland, St. John's, NL, Canada.
Introduction: Early detection of neurodegeneration is essential for optimizing interventions. The highly reproducible progression of neurodegeneration in the decrepit () mouse allows investigation of early biomarkers and mechanisms of brain injury.
Methods: Using high-frequency ultrasound, the common carotid arteries of female and male and control mice were imaged longitudinally at time points bracketing the disease progression (50, 75, and 125 days of age) ( = 6 mice/group/sex).
Dehydrocorydaline maintains the vascular smooth muscle cell contractile phenotype by upregulating Spta1.

Vascular smooth muscle cell (VSMC) phenotypic switching plays a crucial role in the initiation and progression of atherosclerosis. Dehydrocorydaline (DHC), a major active component of the traditional Chinese herbal medicine Rhizoma Corydalis, exhibits diverse pharmacological effects. However, its impact on VSMCs remains largely unknown.

Subarachnoid hemorrhage (SAH) is a type of hemorrhagic stroke, and the neuroprotective effects of nimodipine following SAH have been well-documented. Sirtuin 3 (SIRT3), a mitochondrial nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, plays a significant role in mitigating oxidative stress in various neurodegenerative conditions. However, the role of SIRT3 in the neuroprotective mechanisms of nimodipine after SAH remains unclear.

Objective: To study the associations of genetic markers influencing the residual reactivity of platelets during antiplatelet therapy with acetylsalicylic acid, and clinical and laboratory parameters, including parameters of the platelet hemostasis, in patients with non-cardioembolic ischemic stroke (IS) for a deeper understanding of the pathogenetic mechanisms and prediction of response to therapy and clinical outcome.
Material And Methods: The study included 296 patients (average age 64.65 [55; 76] years) undergoing treatment at the City Clinical Hospital named after.
Berberine Inhibited SASP-Related Inflammation through RXR[Formula: see text]/PPAR[Formula: see text]/NEDD4 Pathway in Atherosclerosis.

The accumulation of aging cells significantly contributes to chronic inflammatory diseases such as atherosclerosis. Human carotid artery single-cell sequencing has shown that large numbers of aging foam cells are present in the plaques of human patients. Berberine (BBR) has been shown to inhibit cell senescence, however, the mechanisms involved in its treatment of atherosclerotic senescence have not yet been determined.
