Gut Microbiota in Ischemic Stroke: Role of Gut Bacteria-Derived Metabolites
AbstractIschemic stroke (IS) remains a leading cause of death and long-term disability globally. Several mechanisms including glutamate excitotoxicity, calcium overload, neuroinflammation, oxidative stress, mitochondrial damage, and apoptosis are known to be involved in the pathogenesis of IS, but the underlying pathophysiology mechanisms of IS are not fully clarified. During the past decade, gut microbiota were recognized as a key regulator to affect the health of the host either directly or via their metabolites. Recent studies indicate that gut bacterial dysbiosis is closely related to hypertension, diabetes, obesity, d...

How People With Diabetes Can Lower Stroke Risk
After spending nearly two decades trying to manage her Type 2 diabetes, Agnes Czuchlewski landed in the emergency room in 2015, with news that she’d just experienced a heart attack. She also learned that she had metabolic syndrome, a cluster of conditions that includes diabetes but also brings higher risk of heart disease and stroke. “Because I needed to lose quite a bit of weight when I was first diagnosed, I was focused on the number I saw on the scale, and then on my blood-sugar numbers,” recalls Czuchlewski, 68, who lives in New York City. “I didn’t realize other numbers came into play, li...

Crocins for Ischemic Stroke: A Review of Current Evidence
Crocins (CRs) and the related active constituents derived from Crocus sativus L. (Saffron) have demonstrated protective effects against cerebral ischemia and ischemic stroke, with various bioactivities including neuroprotection, anti-neuroinflammation, antioxidant, and cardiovascular protection. Among CRs, crocin (CR) has been shown to act on multiple mechanisms and signaling pathways involved in ischemic stroke, including mitochondrial apoptosis, nuclear factor kappa light chain enhancer of B cells pathway, S100 calcium-binding protein B, interleukin-6 and vascular endothelial growth factor-A. CR is generally safe and wel...

Saturated fat link with heart disease questioned
This article is one doctor's opinion based on his own knowledge, research and experience. However, it is fair to say there is an ongoing debate about how far cholesterol is a risk factor for heart disease, especially in people who are otherwise healthy. There is also a similar debate about the use of statins in people who have no evidence of cardiovascular disease. This is alongside ongoing research into the components of LDL and the different types of lipoproteins known to increase risk the most. None of this relevant new evidence is covered by the news reporting.   What should you eat? There is no need to change curren...

Angiotensin Receptor Blockers Versus Angiotensin Converting Enzyme Inhibitors for the Treatment of Arterial Hypertension and the Role of Olmesartan
AbstractBlood pressure lowering by all classes of antihypertensive drugs is accompanied by significant reductions of stroke and major cardiovascular (CV) events. Drugs acting on the renin –angiotensin–aldosterone system, such as angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), showed similar benefit on major CV events to other antihypertensive medications. In real-world practice, ARBs reduced by 10% the incidence of CV mortality, non-fata l myocardial infarction, non-fatal stroke and provided superior protection against CV events than ACEIs in high-risk patients. Despite simila...

Moringa's Health Benefits In Lowering Inflammation
Copyright: Brenda Dawson/UC Davis Moringa is known throughout the world as a miracle tree. But, what exactly is moringa and why is research buzzing about the possible health benefits of this hearty plant? Moringa is a tree that is an important crop native to India and currently grown throughout the world in Latin America, Southeast Asia and Africa. The entire tree is edible, from its roots, flowers, leaves, seeds, gum, fruits and bark. Generally, moringa is consumed by cooking the leaves or immature fruits and more recently as a dried leaf powder used as tea or sprinkled into food. Although 13 species exist in the morin...

A comparative study of the clinical profile of fibrocalculous pancreatic diabetes and type 2 diabetes mellitus
ConclusionsThere are several differences in the phenotype, biochemical parameters, and prevalence of diabetic complications between patients with FCPD and T2DM. Timely diagnosis may have implications in the follow-up and management of patients.

Nrf2 as a Potential Mediator of Cardiovascular Risk in Metabolic Diseases
Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...

Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

Association of a genetic variant in the AKT gene locus and cardiovascular risk factors.
Authors: Kermanshahi F, Ghazizadeh H, Hussein NA, Amerizadeh F, Samadi S, Tayefi M, Kamel Khodabandeh A, Moohebati M, Ebrahimi M, Esmaily H, Sahebi R, Abdulkarimi R, Mousavi SAR, Ferns GA, Avan A, Ghayour-Mobarhan M Abstract Cardiovascular disease (CVDs) is the leading cause of morbidity and death worldwide. Most genetic variants could be identified by several genome-wide-association-studies (GWAS), including within genes encoding proteins involved in the AKT/PI3K pathways that are related with an increased risk of metabolic syndrome and CVDs. Therefore, due to the importance of genetic variants in the prognosis of...
