Can Green Tea, Coffee Reduce Stroke Risk? - Drugs.com MedNews
"The regular action of daily drinking [of] green tea and coffee is a benefit in preventing stroke," said lead researcher Dr. Yoshihiro Kokubo, chief doctor in the department of preventive cardiology at the National Cerebral and Cardiovascular Center, in Osaka.
"If you cannot readily improve your lifestyle, try to prevent stroke by drinking green tea every day," he said.
"Such association studies are still limited in [the] ability to tell whether it is some ingredients in the coffee or tea or some other behavior common to coffee and tea drinkers that is driving the protective effects," said Sacco, chairman of neurology at the University of Miami Miller School of Medicine.

Green tea found to reduce rate of some GI cancers
Now researchers have found that regular tea consumption, defined as tea consumption at least three times a week for more than six months, was associated with a 17 percent reduced risk of all digestive cancers combined. A further reduction in risk was found to be associated with a increased level of tea drinking. Specifically, those who consumed about two to three cups per day (at least 150 grams of tea per month) had a 21 percent reduced risk of digestive system cancers.
For all digestive system cancers combined, the risk was reduced by 27 percent among women who had been drinking tea regularly for at least 20 years," said Nechuta. "For colorectal cancer, risk was reduced by 29 percent among the long-term tea drinkers. These results suggest long-term cumulative exposure may be particularly important."

Beehive Extract Shows Potential as Prostate Cancer Treatment
"If you feed CAPE to mice daily, their tumors will stop growing. After several weeks, if you stop the treatment, the tumors will begin to grow again at their original pace," said Richard B. Jones, PhD, assistant professor in the Ben May Department for Cancer Research and Institute for Genomics and Systems Biology and senior author of the study. "So it doesn't kill the cancer, but it basically will indefinitely stop prostate cancer proliferation."
"A typical problem in bringing some of these herbal remedies into the clinic is that nobody knows how they act, nobody knows the mechanism, and therefore researchers are typically very hesitant to add them to any pharmaceutical treatment strategy," Jones said. "Now we'll actually be able to systematically demonstrate the parts of cell physiology that are affected by these compounds."

Endothelial Function Improvement With Dietary (Cocoa) Flavanols in Patients With Coronary Artery Disease....
A new study by UCSF cardiologists and researchers lead by Dr. Yerem Yeghiazarians found that high concentrations of cocoa flavanols decrease blood pressure, improve the health of blood vessels and increase the number of circulating blood-vessel-forming cells in patients with heart disease. The findings indicate that foods rich in flavanols such as cocoa products, tea, wine, and various fruits and vegetables have a cardio-protective benefit for heart disease patients.
Flavanols are phytonutrient compounds that are found naturally in apples, grapes, tea, cocoa and cherries, which account for the antioxidant effect provided by red wine and green tea. The study found a protective effect from a cocoa drink with 375 mg of flavanols, but according to researchers, a standard or recommended dosage has not yet been defined to achieve optimal health benefit.
The UCSF team has shown for the first time that one of the possible mechanisms of flavanol's benefit is an increase in the circulation of so-called angiogenic cells in the blood. These cells, also known as early endothelial progenitor cells, are critical for the repair process after vascular injury, and perform function and maintenance roles in the endothelium. Endothelium is the thin layer of cells that line the interior wall of blood vessels.
In the current study, the benefit seen from the two-fold increase in circulating angiogenic cells was similar to that achieved by therapy with statins and with lifestyle changes such as exercise and smoking cessation. The benefit demonstrated with cocoa flavanol therapy occurred in addition to the medical regimen already being taken by study participants.
"Our data support the concept that dietary flavanols at the levels provided -- in tandem with current medical therapy -- are safe, improve cardiovascular function, and increase circulating angiogenic cells, which have previously been shown to correlate positively with long-term cardiovascular outcomes" said Yeghiazarians.
Though long-term trials examining the effects of high-flavanol diets on cardiovascular health and function are warranted, but these early findings help us understand how these compounds impact the function of damaged blood vessels...

ProstaCaid (33-ingredient comprehensive polyherbal preparation) against prostate cancer......
Herbal extracts include the extracts from turmeric root, saw palmetto berry, grape skin, pomegranate, pumpkin seed, pygeum bark, sarsaparilla root, green tea, and Japanese knotweed. Hence, it is rich in natural polyphenols, including quercetin, resveratrol, epigallocatechin gallate (EGCG), and ellagic acid, which have previously demonstrated anticancer potential. The unique formula contains 3 medicinal mushrooms grown on an herbal-enhanced medium. The mushrooms included are Phellinus linteus, Ganoderma lucidum, and Coriolus versicolor, each with known anticancer properties.
Researchers claim that, ProstaCaid was designed based on constituents that exhibit antiprolifetaive, antioxidant, and apoptotic activities; however, its efficacy and the mechanisms of action are yet to be examined. Researchers looked at the effectiveness of the preparation in suppressing several types of prostate cancer cell lines in culture and attempt to delineate the mechanism of action for justification in pursuing animal to determine efficicacy invivo.
Researchers conclude that, the anticancer activity of ProstaCaid may be ascribed to its polyphenolic flavonoids and curcuminoids derived from various herbs as well as other supplements, such as DIM. The preparation contains supplements such as quercetin (15%), Curcuma longa root extract complex with enhanced bioavailability (BCM-95; 20%), DIM (3%), and resveratrol (0.2%). Some of these components have shown a strong doseand time-dependent growth inhibition and apoptotic death in prostate cancer cells; 25 mM of quercetin inhibited about 50% PC3 cell growth for 72 hours. At 24 hours, 50 mM and 100 mM quercetin induced G2/M arrest and apoptosis, manifested by the decrease in G2/M-related protiens.
Researchers summarise that, ProstaCaid has anti-cancer activities in both AD and AI prostate cancer cells at very low concentrations (25 mg/mL). It also suggests that ProstaCaid inhibits cell growth and survival, at least through the inhibition of AKT and MAPK signaling. The effect on AI cell lines is especially of importance as there is presently no curative therapy for hormone refractory prostate cancer.
Researchers postulate that ProstaCaid may affect activity of Cdc2/cyclin B1 kinase by reducing this complex formation. Cdc2 could be dephosphorylated by Cdc25C and become inactive or be phosphorylated by protein kinase, such as Wee1, and then converted into an inactive form. They also suggest that more studies are needed in the future to test it and to define its upstream events in PC3 cells.

Polyphenols in red wine and green tea halt prostate cancer growth, study suggests
"The profound impact that the antioxidants in red wine and green tea have on our bodies is more than anyone would have dreamt just 25 years ago," Weissmann added. "As long as they are taken in moderation, all signs show that red wine and green tea may be ranked among the most potent 'health foods' we know." ....
