Preliminary analysis of immunoregulatory mechanism of hyperhomocysteinemia-induced brain injury in Wistar-Kyoto rats
In conclusion, the present study indicated that HHcy can promote inflammation by triggering Treg/Th17 immune imbalance to ameliorate the brain tissue damage.PMID:33790992 | PMC:PMC8005698 | DOI:10.3892/etm.2021.9914

Pyridoxal Isonicotinoyl Hydrazone Improves Neurological Recovery by Attenuating Ferroptosis and Inflammation in Cerebral Hemorrhagic Mice
Biomed Res Int. 2021 Sep 8;2021:9916328. doi: 10.1155/2021/9916328. eCollection 2021.ABSTRACTFerroptosis and inflammation induced by cerebral hemorrhage result in an excessive inflammatory response and irreversible neuronal injury. Alleviating ferroptosis might be an effective way to prevent neuroinflammatory injury and promote neural functional recovery. Pyridoxal isonicotinoyl hydrazine (PIH), a lipophilic iron-chelating agent, has been reported to reduce excess iron-induced cytotoxicity. However, whether PIH could ameliorate the effects of hemorrhagic stroke is not completely understood. In the present study, the preven...

The Role of Vitamin Supplementation in the Prevention of Cardiovascular Disease Events
ABSTRACT The production, sale, and consumption of multiple vitamins is a multibillion‐dollar industry. Most Americans take some form of supplement ostensibly for prevention of cardiovascular disease. It has been claimed that vitamin A retards atherogenesis. Vitamin C is an antioxidant and is thought to possibly decrease free radical‐induced endothelial injury, which can lead to atherosclerotic plaque formation. Vitamin E has been extensively studied for its possible effects on platelet function as well as inhibition of foam‐cell formation. Low levels of vitamin D have been thought to negatively impact myocardial stru...

Interventions for lowering plasma homocysteine levels in dialysis patients.
CONCLUSIONS: Homocysteine-lowering therapies were not found to reduce mortality (cardiovascular and all-cause) or cardiovascular events among people with ESKD. PMID: 27243372 [PubMed - as supplied by publisher]

UPDATE: How Much Vitamin D Should You Take?
Conclusions What is the sweet spot for vitamin D and longevity? All studies are in agreement: 40-50 ng/ml. If I had a (working) magic wand, I'd make this range much broader - but, there it is. Since it is narrow, let's cover the main sources of Vitamin D and figure out how you can get to the exact target. Sources of vitamin D We get vitamin D from supplements, sun and food--and in that order for most of us. Food Considering that we need thousands of IU's of vitamin D per day, food doesn't have that much. Some of the highest sources have only a few hundred units. Food sources of Vitamin D:[13] Salmon: 4 oz. = 500 IU...

Homocysteine and non-cardiac vascular disease.
Abstract Elevated homocysteine (Hcy) levels are predictors of cardiovascular disease (CVD). Hyperhomocysteinemia has also been associated with total and CVD mortality. However, whether Hcy is just a marker or plays a causal role in CVD remains to be elucidated. In this narrative review, we discuss the associations between Hcy and non-cardiac vascular diseases, namely stroke, peripheral artery disease (PAD), carotid artery disease, chronic kidney disease (CKD), atherosclerotic renal artery stenosis (ARAS), abdominal aortic aneurysm (AAA) and erectile dysfunction (ED). The effects of several drugs on Hcy levels are ...

B vitamins and cognition in subjects with small vessel disease: An extension study of VITATOPS, a randomized, placebo-controlled trial
VITAmins TO Prevent Stroke (VITATOPS) study, a randomized, double-blind international multi-centre trial involving 8164 subjects in studying effect of lowering homocysteine level by daily administration of B-vitamins (2mg folic acid, 25mg vitamin B6, and 0.5mg vitamin B12) failed to demonstrate a positive effect of B-vitamins in reducing incidence of major vascular events and global cognition decline as measured by mini-mental state examination (MMSE) score [1,2]. However, assessment of cognition using MMSE alone has its limitations and a full neuropsychological assessment of different cognitive domains will provide more robust evidence.

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...

Increasing Upstream Chromatin Long –Range Interactions May Favor Induction of Circular RNAs in LysoPC-Activated Human Aortic Endothelial Cells
We examined the sponging potential of all significantly changed circRNAs using the CircInteractome database (Montefiori et al., 2018), recording two miRNAs with four or more predicted binding sites in a single circRNA transcript, a threshold above which meaningful sponging activity is likely to occur Memczak et al. (2013). Another four significantly changed circRNAs are experimentally shown to sponge miRNAs (Dudekula et al., 2016; Chen et al., 2017; Yan et al., 2017; Wang et al., 2018), for six total circRNAs with miRNA sponging activity including miR125, miR143, miR1272, miR153, miR515-5p, and miR196a-5p (Table 4). In Fig...

5 Minutes To Better Heart Health
Americans are living through a blood pressure crisis. Maybe you, or someone you love, is one of them… In the United States, 65% of adults over the age of 50 are living with above-normal blood pressure – increasing their risk of heart attack and stroke. And that’s just the tip of the iceberg. Because high blood pressure can also put you at higher risk for developing dementia later in life.1 Of course, Big Pharma doesn’t see this as a big problem. They know they can use this crisis to sell more drugs… drugs that never fail to do more harm than good. But a new study reveals how you can lower blood pressure – a...
