Edaravone Dexborneol Alleviates Neuroinflammation by Reducing Neuroglial Cell Proliferation and Suppresses Neuronal Apoptosis/Autophagy in Vascular Dementia Rats
In this study, we established the VD model of rats by bilateral carotid artery occlusion to explore the neuroprotective effect of EDB and its mechanism. Morris Water Maze test was applied to assess the cognitive function of rats. H&E and TUNEL staining were applied to observe the cellular structure of the hippocampus. Immunofluorescence labeling was used to observe the proliferation of astrocytes and microglia. ELISA was applied to examine the levels of TNF-α, IL-1β and IL-6, and RT-PCR was applied to examine their mRNA expression levels. Western blotting was applied to examine apoptosis-related proteins (Bax, Bcl-2,...

A nationwide cohort study comparing the effectiveness of diuretics and calcium channel blockers on top of renin-angiotensin system inhibitors on chronic kidney disease progression and mortality.
It is unknown whether initiating diuretics on top of renin-angiotensin system inhibitors (RASi) is superior to alternative antihypertensive agents such as calcium channel blockers (CCBs) in patients with chronic kidney disease (CKD). For this purpose, we emulated a target trial in the Swedish Renal Registry 2007-2022 that included nephrologist-referred patients with moderate-advanced CKD and treated with RASi, who initiated diuretics or CCB. Using propensity score-weighted cause-specific Cox regression, we compared risks of major adverse kidney events (MAKE; composite of kidney replacement therapy [KRT], experiencing over ...

Intracranial Spotty Calcium Predicts Recurrent Stroke in Patients with Symptomatic Intracranial Atherosclerotic Stenosis
ConclusionIn patients with symptomatic ICAS, intracranial spotty calcium is an independent predictor of recurrent ischemic stroke, which will further facilitate risk stratification and suggest that more aggressive treatment should be considered for these patients.

Effects of intensive lipid lowering compared with moderate-intensity lipid lowering on coronary atherosclerotic plaque phenotype and major adverse cardiovascular events in adults with low to intermediate 10-year ASCVD risk (ILLUMINATION study): protocol for a multicentre, open-label, blinded-endpoint, randomised controlled trial
Introduction Current guidelines recommend moderate-intensity lipid lowering (low-density lipoprotein cholesterol, LDL-C of <2.6 mmol/L or 30%–49% reduction from the baseline) for patients with intermediate 10-year atherosclerotic cardiovascular disease (ASCVD) risk. The effects of intensive lipid lowering (LDL-C of <1.8 mmol/L) on coronary atherosclerotic plaque phenotype and major adverse cardiovascular events (MACE) in adults with both non-obstructive coronary artery disease (CAD) and low to intermediate 10-year ASCVD risk remain uncertain. Methods and analysis Intensive Lipid-lowering for Plaque and Major A...

Association of oral bisphosphonates with cardioembolic ischemic stroke: a nested case-control study
Conclusion: The use of oral bisphosphonates increases specifically the odds of cardioembolic IS, in a duration-dependent manner, while leaves materially unaffected the odds of non-cardioembolic IS.

Plasma exosome proteomics reveals the pathogenesis mechanism of post-stroke cognitive impairment
Aging (Albany NY). 2023 May 20;15. doi: 10.18632/aging.204738. Online ahead of print.ABSTRACTExploration and utilization of exosome biomarkers and their related functions provide the possibility for the diagnosis and treatment of post-stroke cognitive impairment (PSCI). To identify the new diagnostic and prognostic biomarkers of plasma exosome were uzed label-free quantitative proteomics and biological information analysis in PSCI patients. Behavioral assessments were performed, including the Mini-Mental Status Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the Barthel index, the Morse Fall Seale (MFS) betwe...

Subclinical Vascular Composites Predict Clinical Cardiovascular Disease, Stroke, and Dementia: The Multi-Ethnic Study of Atherosclerosis (MESA)
CONCLUSIONS: Subclinical vascular composites of arteriosclerosis and atherosclerosis may be useful biomarkers to inform the vascular pathways contributing to events of CVD, CHD, stroke, and dementia.PMID:37205504 | PMC:PMC10187443 | DOI:10.1101/2023.05.01.23289364

Neuroprotective effect of aloe emodin against Huntington's disease-like symptoms in R6/1 transgenic mice
Food Funct. 2023 May 16. doi: 10.1039/d3fo00156c. Online ahead of print.ABSTRACTAloe emodin is a natural anthraquinone derived from aloe or rhubarb, showing anti-renal fibrosis, anti-atherosclerosis and anti-cancer effects. Aloe emodin also shows neuroprotective effects in ischemic stroke rats. Naturally, anthraquinone derivatives generally have the effect of inhibiting the transforming growth factor-β1 (TGF-β1) pathway. There is an increase in the calcium/calmodulin-dependent protein kinase II (CaMKII) and TGF-β1 levels in both Huntington's disease (HD) patients' brains and HD transgenic mice. Thus, we hypothesized tha...

Single Molecule Mechanics and Kinetics of Cardiac Myosin Interacting with Regulated Thin Filaments
Biophys J. 2023 May 10:S0006-3495(23)00306-5. doi: 10.1016/j.bpj.2023.05.008. Online ahead of print.ABSTRACTThe cardiac cycle is a tightly regulated process wherein the heart generates force to pump blood to the body during systole and then relaxes during diastole. Disruption of this finely tuned cycle can lead to a range of diseases including cardiomyopathies and heart failure. Cardiac contraction is driven by the molecular motor myosin, which pulls regulated thin filaments in a calcium-dependent manner. In some muscle and non-muscle myosins, regulatory proteins on actin tune the kinetics, mechanics, and load dependence o...
