Cocoa tea (Camellia ptilophylla) is a naturally decaffeinated tea plant. Previously we found that cocoa tea demonstrated a beneficial effect against high-fat diet induced obesity, hepatic steatosis, and hyperlipidemia in mice. The present study aimed to investigate the anti-adipogenic effect of cocoa tea in vitro using preadipocytes 3T3-L1. Adipogenic differentiation was confirmed by Oil Red O ...
Microbial resistance to antibiotics has become an increasing global problem and there is a need to find out novel potent antimicrobial agents with alternative modes of action as accessories to antibiotic therapy. This study investigated the antioxidant, antimicrobial and synergistic properties of tea polyphenols. The tea germplasm from Kenya, China and Japan that are grown in Kenya were charact...
Intake of flavonoids is associated with a reduced cardiovascular risk. Oxidation of LDL is a major step in atherogenesis, and antioxidants may protect LDL from oxidation. Because tea is an important source of flavonoids, which are strong antioxidants, we have assessed in a randomized, placebo-controlled study the effect of consumption of black and green tea and of intake of isolated green tea p...
In a recently published paper in the "British Medical Journal", a joint collaboration of well-known international scientists represented by Islami et al. has tackled this issue.1 In a well-designed, laborious case-control study in Golestan, Iran, they looked at 300 cases of esophageal SCC and 571 age and sex matched neighborhood controls, assessed the temperature of the commonly used drink "tea...
هیدراکسی آپاتیت (ha) به علت تشابه زیاد به فاز معدنی استخوان، دارای زیست¬سازگاری بالایی است. ولی ha خواص مکانیکی ضعیفی دارد بنابراین اغلب از پوشش¬های آن روی کاشتنی¬های فلزی استفاده می¬شود. تثبیت بیولوژیکی کاشتنی در بدن از طریق رشد استخوان به داخل تخلخل¬های پوشش آن رخ می¬دهد. بنابراین پارامتر تخلخل بسیار مهم است. استحکام ماده با افزایش تخلخل آن کاهش می¬یابد. در نتیجه افزودن فاز دوم تقویت کننده با...
We conducted this study to examine the effects of safflower seed granular tea containing physiologically active polyphenols on antioxidative activities and bone metabolism. Forty postmenopausal women ages 49 to 64-years were recruited from Daegu and Gyeongbuk and were randomly assigned to either a safflower tea supplement (Saf-tea) group (n = 27) or a placebo group (n = 13). The Saf-tea group r...
The goal of this study was to determine the mechanisms involved in the transport of the organic cation, tetraethylammonium (TEA), across the apical membrane of OK cells. [14C]TEA accumulated in OK cell monolayers reaching equilibrium in 2 h. The uptake of [14C]TEA at equilibrium was dependent upon temperature and was inhibited by sodium azide and by various organic cations, including N1-methyln...
Background & Aims of the Study: Tea is one of the most important beverages that consumes in several parts of the world including Iran. Tea plant can be contaminated during manufacturing processes and growth period by pollutants such as heavy metals. In this study, the concentration of some heavy metals in different brands of both Iranian and imported black tea to Iran was inves...
Introduction: Increasing of food-related diseases has led to the perception of diet importance. Plant-derived products (especially tea) as important sources of antioxidant and antimicrobial compounds play a major role in reducing food pathogens. In this study, total phenolic content, antioxidant and antimicrobial activity of four tea extracts including green tea, white, black and red teas were ...
OBJECTIVES The essential oil of Melaleuca alternifolia (tea tree oil) and its components have antimicrobial activity against a wide range of Gram-positive and Gram-negative bacteria, fungi and viruses. The mechanism(s) by which Pseudomonas aeruginosa NCTC 10662 maintains a decreased susceptibility to tea tree oil and components was investigated. RESULTS Ethylene diamine tetraacetic acid enhan...
