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,...

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

High Blood Pressure and Diabetes Are Linked. Here ’ s How to Reduce Your Risk for Both
High blood pressure—also known as hypertension—and Type 2 diabetes are two of the most common medical conditions in the U.S. Unfortunately, they often occur together. Some research has found that 85% of middle-aged or older adults who have Type 2 diabetes also have hypertension, and both conditions elevate a person’s risk for heart disease, stroke, and kidney disease.
These increased risks are significant, and in some cases grave. Researchers have found that people with Type 2 diabetes are up to four times more likely to develop cardiovascular disease than those who don’t have the conditio...

Recurrent Transient Ischemic Attack Induces Neural Cytoskeleton Modification and Gliosis in an Experimental Model
Transl Stroke Res. 2022 Jul 22. doi: 10.1007/s12975-022-01068-7. Online ahead of print.ABSTRACTTransient ischemic attack (TIA) presents a high risk for subsequent stroke, Alzheimer's disease (AD), and related dementia (ADRD). However, the neuropathophysiology of TIA has been rarely studied. By evaluating recurrent TIA-induced neuropathological changes, our study aimed to explore the potential mechanisms underlying the contribution of TIA to ADRD. In the current study, we established a recurrent TIA model by three times 10-min middle cerebral artery occlusion within a week in rat. Neither permanent neurological deficit nor ...

The Ca2+-gated channel TMEM16A amplifies capillary pericyte contraction and reduces cerebral blood flow after ischemia
Pericyte-mediated capillary constriction decreases cerebral blood flow in stroke after an occluded artery is unblocked. The determinants of pericyte tone are poorly understood. We show that a small rise in cytoplasmic Ca2+ concentration ([Ca2+]i) in pericytes activated chloride efflux through the Ca2+-gated anion channel TMEM16A, thus depolarizing the cell and opening voltage-gated calcium channels. This mechanism strongly amplified the pericyte [Ca2+]i rise and capillary constriction evoked by contractile agonists and ischemia. In a rodent stroke model, TMEM16A inhibition slowed the ischemia-evoked pericyte [Ca2+]i rise, ...

What the Science Says About the Health Benefits of Vitamins and Supplements
From multivitamins and melatonin to fiber and fish oil, Americans who are trying to boost their health and immunity have a plethora of supplements to choose from. An estimated 58% of U.S. adults ages 20 and over take dietary supplements, according to the U.S. Centers for Disease Control and Prevention, and the supplement industry is valued at more than $30 billion a year. Supplement use has been growing rapidly over the past few decades along with the wellness industry.
“The popular belief is that a supplement is going to be helpful for promoting health,” says Fang Fang Zhang, a professor at Tufts University&rs...

The New Era of Retinal Imaging in Hypertensive Patients
Structural and functional alterations in the microcirculation by systemic hypertension can cause significant organ damage at the eye, heart, brain, and kidneys. As the retina is the only tissue in the body that allows direct imaging of small vessels, the relationship of hypertensive retinopathy signs with development of disease states in other organs have been extensively studied; large-scale epidemiological studies using fundus photography and advanced semi-automated analysis software have reported the association of retinopathy signs with hypertensive end-organ damage includes the following: stroke, dementia, and coronar...

Microglial Activation Modulated by P2X4R in Ischemia and Repercussions in Alzheimer ’s Disease
There are over 80 million people currently living who have had a stroke. The ischemic injury in the brain starts a cascade of events that lead to neuronal death, inducing neurodegeneration which could lead to Alzheimer’s disease (AD). Cerebrovascular diseases have been suggested to contribute to AD neuropathological changes, including brain atrophy and accumulation of abnormal proteins such as amyloid beta (Aβ). In patients older than 60 years, the incidence of dementia a year after stroke was significantly increased. Nevertheless, the molecular links between stroke and dementia are not clearly understood but could be r...

Hypertension Management in Primary Care in the Capital Area of Iceland
CONCLUSION: As has recently been shown in epidemiologic studies hypertension in Iceland is both underdiagnosed and undertreated although the country ranks high on both counts in international comparison. Furthermore, the fact that under half of hypertensive patients in general practice in the capital area reach the targeted treatment goals, cannot be considered an acceptable. Thus, it is of immense importance to improve both the diagnosis and the treatment of HT.PMID:35103619 | DOI:10.17992/lbl.2022.02.675
