Protective Effect of Epigallocatechin Gallate on Endothelial Disorders in Atherosclerosis
Abstract: Healthy vascular endothelial cells regulate vascular tone and permeability, prevent vessel wall inflammation, enhance thromboresistance, and contribute to general vascular health. Furthermore, they perform important functions including the production of vasoactive substances such as nitric oxide (NO) and endothelium-derived hyperpolarizing factors, as well as the regulation of smooth muscle cell functions. Conversely, vascular endothelial dysfunction leads to atherosclerosis, thereby enhancing the risk of stroke, myocardial infarction, and other cardiovascular diseases (CVDs). Observational studies and randomiz...

Study: Drinking Tea May Help You Live Longer, Especially If It ’ s Green
This study strengthens the body of evidence that habitual tea drinking is associated with lower rates of atherosclerotic cardiovascular disease, though it cannot prove that it’s definitely the tea that’s responsible,” Dr. Jenna Macciochi, a lecturer in immunology at the University of Sussex, told the SMC. However, she noted that “a body of evidence in nutrition suggests that whole diet patterns are more informative of diet-disease relationships than any isolated food or nutrient.” Dr. Duane Mellor, a registered dietitian and senior teaching fellow at Aston Medical School, Aston University, sai...

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...

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...

Liver Injury Associated with Sporting Activities
Semin Liver Dis 2018; 38: 357-365 DOI: 10.1055/s-0038-1670656Exertional heat stroke most commonly develops following prolonged levels of aerobic activity in a warm or humid environment. Hypoperfusion of the vital organs along with activation of the inflammasome can lead to progressive and potentially fatal multiorgan failure including acute liver failure. In the United States, herbal and dietary supplements that are marketed to improve performance, strength, and weight loss are increasingly being used by both amateur and professional athletes. Consumption of bodybuilding supplements that contain androgenic anabolic steroid...

Green Tea and Red Tea from Camellia sinensis Partially Prevented the Motor Deficits and Striatal Oxidative Damage Induced by Hemorrhagic Stroke in Rats.
In this study, we investigated the effects of supplementation with green tea and red tea from Camellia sinensis on motor deficits and striatum oxidative damage in rats submitted to hemorrhagic stroke (ICH). Male Wistar rats were supplemented with green tea, red tea, or vehicle for 10 days prior to ICH induction. After injury, the rats were submitted to motor tests (open field for locomotion, rotarod for balance, and neurological deficit scale (NDS)) 1, 3, and 7 days after ICH induction, while the tea supplementation was maintained. Subsequently, the rats were euthanized to striatal tissue dissection for biochemical analyze...

Out From Under the FDA ’s Heel
A medical revolution is happening as we speak… And the great state of Texas is leading the charge. It started because people like you finally got fed up with the chokehold the FDA has on medicine. Let me explain… The FDA is controlled by bureaucrats who were hired from Big Pharma and the medical establishment. They refuse to approve life-saving therapies without years of tightly controlled clinical trials. In the meantime, real people are suffering. And even dying. But Texas is on track to become the first state to explicitly back stem cell therapies. And it’s about time states took this power away from the F...

Supplementation with different teas from Camellia sinensis prevents memory deficits and hippocampus oxidative stress in ischemia-reperfusion
Publication date: September 2017 Source:Neurochemistry International, Volume 108 Author(s): Alexandre Martins, Helen L. Schimidt, Alexandre Garcia, Caroline Dalla Colletta Altermann, Francielli W. Santos, Felipe P. Carpes, Weber Cláudio da Silva, Pâmela B. Mello-Carpes Memory and cognition impairments resultant of ischemic stroke could be minimized or avoided by antioxidant supplementation. In this regard, the neuroprotective potential of Green tea from Camellia sinensis has been investigated. However, there is a lack of information regarding the neuroprotective potential of others teas processed from the Camellia sinen...

Short-term green tea supplementation prevents recognition memory deficits and ameliorates hippocampal oxidative stress induced by different stroke models in rats.
This study investigate the effect of green tea (GT) on short and long term declarative memory and oxidative damage induced by transient ischemia-reperfusion (IR) and intracerebral hemorrhage (ICH) in rats. Male Wistar rats were divided into 8 groups of 10 according the stroke type induced were used: Sham IR, Sham IR+GT, IR, IR+GT, Sham ICH, Sham ICH+GT, ICH, ICH+GT. Supplementation with GT was initiated 10days before stroke surgery and continuous for 6days after (GT dose 400mg/kg). Short (STM) and long term memory (LTM) we evaluated with object recognition task (OR) and hippocampus were used to evaluate parameters related ...

Green tea consumption and risk of cardiovascular disease or stroke
Pang et al. evaluated the association between green tea consumption and the risk of cardiovascular disease (CVD) or ischemic related diseases, and a total of 9 studies on Japanese were included for their meta-analysis [1]. Odds ratios (ORs) (95% confidence intervals (CIs)) of those who didn't consume green tea for CVD, intracerebral hemorrhage, and cerebral infarction were 1.19 (1.09–1.29), 1.24 (1.03–1.49), and 1.15 (1.01–1.30) compared to

Rooibos: Better Than Green Tea For Many Reasons
When I hiked Table Mountain on my last trip to South Africa, the locals told me about an herb that is better than green tea that kept them disease-free. African Bushmen have used this herb since before recorded history, but it’s still pretty rare here in America. Studies on this plant are being done all over the world. But not in the U.S. Because Big Pharma and the FDA aren’t interested in a natural cure that can’t be patented — or profited from. What is This South African Herb? I’m talking about an herb called Rooibos — or red bush in Afrikaans. Rooibos (pronounced roy-boss) provides a whole lo...

Delayed Treatment with Green Tea Polyphenol EGCG Promotes Neurogenesis After Ischemic Stroke in Adult Mice
In this study, C57BL/6 mice underwent middle cerebral artery occlusion (60 min) followed by reperfusion for 28 days. Neural progenitor cells (NPCs) were isolated from ipsilateral subventricular zone (SVZ) at 14 days post-ischemia (dpi). The effects of EGCG on the proliferation and differentiation of NPCs were examined in vivo and in vitro. Behavioral assessments were made 3 days before MCAO and at 28 dpi. SVZ NPCs were stimulated with lipopolysaccharide (LPS) in vitro to mimic the inflammatory response after ischemic stroke. We found that 14 days treatment with EGCG significantly increased the proliferation of SVZ NP...
