Molecules, Vol. 23, Pages 1788: Protection of Anthocyanin from Myrica rubra against Cerebral Ischemia-Reperfusion Injury via Modulation of the TLR4/NF- κB and NLRP3 Pathways
In this study, we prepared eight purified anthocyanin extracts (PAEs) from different types of MR, and examined the amounts of total anthocyanin (TA) and cyanidin-3-O-glucoside (C-3-G). After one week of PAE treatment, the cerebral infarction volume, disease damage, and contents of nitric oxide and malondialdehyde were reduced, while the level of superoxide dismutase was increased in I/R mice. Altogether, our results show that Boqi1 MR contained the most TA (22.07%) and C-3-G (21.28%), and that PAE isolated from Dongkui MR can protect the brain from I/R injury in mice, with the mechanism possibly related to the Toll-like re...

Breast cancer susceptibility protein 1 (BRCA1) rescues neurons from cerebral ischemia/reperfusion injury through NRF2-mediated antioxidant pathway
In conclusion, enhanced BRCA1 after cerebral I/R injury may attenuate or prevent neural damage from I/R via NRF2-mediated antioxidant pathway. The finding may provide a potential therapeutic target against ischemic stroke.

Molecules, Vol. 23, Pages 765: Small Molecule Catalysts with Therapeutic Potential
aus Jacob Catalysts are employed in many areas of research and development where they combine high efficiency with often astonishing selectivity for their respective substrates. In biology, biocatalysts are omnipresent. Enzymes facilitate highly controlled, sophisticated cellular processes, such as metabolic conversions, sensing and signalling, and are prominent targets in drug development. In contrast, the therapeutic use of catalysts per se is still rather limited. Recent research has shown that small molecule catalytic agents able to modulate the redox state of the target cell bear considerable promise, particularly...

A New Form of This Miracle Nutrient Is 8 Times More Powerful …
CoQ10 has made the mainstream. You can find it everywhere. But the type of CoQ10 I want to tell you about has been completely ignored. That’s too bad, because this new form is 8 times better at getting into your blood and staying there. And that’s where it has its miracle-like anti-aging effects. This new form of CoQ10 may give you the opportunity to live disease-free for the rest of your life. Today, I’ll show you how this new “reduced” form of CoQ10 gives you greater power to prevent and reverse disease. You’ll also discover that it ramps up your energy levels and slows your aging process down by a remarkable...

Plasma Metal Concentrations and Incident Coronary Heart Disease in Chinese Adults: The Dongfeng-Tongji Cohort
Conclusions: Our study suggested that incident CHD was positively associated with plasma levels of titanium and arsenic, and inversely associated with selenium. Additional research is needed to confirm these findings in other populations. https://doi.org/10.1289/EHP1521 Received: 22 December 2016 Revised: 17 September 2017 Accepted: 19 September 2017 Published: 19 October 2017 Address correspondence to T.

Review on antioxidants and evaluation procedures
AbstractAntioxidants are the substances that are capable of counteracting the damaging effects of the physiological process of oxidation occur in animal tissues. These may be nutrients (vitamins and minerals) as well as enzymes (proteins) in our body that assist in chemical reactions. They are believed to play a role in preventing the development of chronic diseases like cancer, diabetes, heart disease, stroke, Alzheimer's disease, rheumatoid arthritis, and cataracts etc. The present review article emphasizes on the various aspects of oxidants and antioxidants viz. definition, types, causes, mechanism, functions, adverse e...

3 Reasons to Feel Good About Drinking Coffee on National Coffee Day
People often think about their relationship with coffee as a bad habit: maybe they splurge too frequently on $4 lattes (free coffee deals only come around once a year), or they’re so dependent on their morning pot of coffee that they can’t function without it. While there is a case to be made for not overdoing it, there are also plenty of reasons to embrace your daily coffee ritual without guilt. Yes, there’s the taste, the aroma, and the way coffee brings those fuzzy mornings into focus. But in recent years, research has also suggested that coffee has real health perks—and that for many people, the...

The Association of Arsenic Metabolism with Cancer, Cardiovascular Disease, and Diabetes: A Systematic Review of the Epidemiological Evidence
Conclusions: Population level of iAs% and DMA%, but not MMA%, were associated with arsenic exposure levels. Overall, study findings suggest that higher MMA% was associated with an increased risk of cancer and cardiovascular disease, while lower MMA% was associated with an increased risk of diabetes and metabolic syndrome. Additional population-based studies and experimental studies are needed to further evaluate and understand the role of arsenic exposure in arsenic metabolism and the role of arsenic metabolism in disease development. https://doi.org/10.1289/EHP577 Received: 01 June 2016 Revised: 26 February 2017 Acce...

IJERPH, Vol. 14, Pages 854: Treatment of Human Placental Choriocarcinoma Cells with Formaldehyde and Benzene Induced Growth and Epithelial Mesenchymal Transition via Induction of an Antioxidant Effect
In this study, the effects of formaldehyde (FA) and benzene (Bz), the main components of CS, on cell proliferation and epithelial mesenchymal transition (EMT) of JEG-3 human choriocarcinoma cells were examined to confirm the relationship between CS components and placenta carcinoma. Upon MTT assay, FA (10−8 M to 10−5 M) and Bz (10−11 M to 10−8 M) increased JEG-3 cell proliferation. Western blot assay revealed that the protein expression of cyclin D1 and E1 increased, while the levels of p21 and p27 were reduced following treatment. In Scratch assay, FA (10−8 M and 10−5 M) and Bz (10−11 M and 10−8 M) increas...

Polyamines: therapeutic perspectives in oxidative stress and inflammatory diseases.
Abstract Polyamines are naturally occurring aliphatic compounds, particularly essential elements for biological functions. These compounds play a central role in regulating molecular pathways which are responsible for cellular proliferation, growth, and differentiation. Importantly, excessive polyamine catabolism can lead to a prominent source of oxidative stress which increases inflammatory response and thought to be involved in several diseases including stroke, renal failure, neurological disease, liver disease, and even cancer. Moreover, polyamine supplementation increases life span in model organisms and may ...

Antioxidant Vitamin Intake and Mortality: The Leisure World Cohort Study.
Abstract To assess the relationship between antioxidant vitamin intake and all-cause mortality in older adults, we examined these associations using data from the Leisure World Cohort Study, a prospective study of residents of the Leisure World retirement community in Laguna Hills, California. In the early 1980s, participants (who were aged 44-101 years) completed a postal survey, which included details on use of vitamin supplements and dietary intake of foods containing vitamins A and C. Age-adjusted and multivariate-adjusted (for factors related to mortality in this cohort-smoking, alcohol intake, caffeine consu...
