Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Apelin-13 Suppresses Neuroinflammation Against Cognitive Deficit in a Streptozotocin-Induced Rat Model of Alzheimer ’s Disease Through Activation of BDNF-TrkB Signaling Pathway
Conclusion The data in this manuscript demonstrates that apelin-13 upregulates BDNF against STZ-induced congnitive impairment by suppressing glial cell activity and inflammatory factors release. This suggests apelin signaling may be a new target in the treatment of AD. Ethics Statement All experimental protocols were carried out according to the National Institutes of Health Guide for the Care and Use of Laboratory Animals approved by the Central South University at XiangYa Animal Care and Use Committee. Author Contributions XqQ and LH conceived the study and contributed to its experimental design. HqL carried out the...

Straight from the heart: Mysterious lipids may predict cardiac problems better than cholesterol
Stephanie Blendermann, 65, had good reason to worry about heart disease. Three of her sisters died in their 40s or early 50s from heart attacks, and her father needed surgery to bypass clogged arteries. She also suffered from an autoimmune disorder that results in chronic inflammation and boosts the odds of developing cardiovascular illnesses. “I have an interesting medical chart,” says Blendermann, a real estate agent in Prior Lake, Minnesota. Yet Blendermann’s routine lab results weren’t alarming. At checkups, her low-density lipoprotein (LDL), or “bad,” cholesterol hovered around the 100 milligrams-per-...
