background: two of the important radionuclides which are entered to environment and human diet are radium-226 (226ra) and cesium-137 (137cs). it is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. an experiment has been performed at the environmental monitoring section...

Natural remedies from medicinal plants are considered to be effective and safe alternative treatment for diabetes mellitus. The aim of the present study was to investigate the hypoglycemic activity of the crude tea leaves extract on streptozotocin (STZ)-induced diabetic mice. The average body weight of animals with diabetes and their percentage changes of body weight gain after 15 and 30 days w...

After water, tea is the world’s most widely consumed beverage. Tea is enjoyed by many people for its cooling and slightly bitter flavor and is known to have many particular health benefits [1-3]. There are several types of tea according to its fermentation processes such as black tea, oolong tea, white tea, yellow tea and green tea [4,5]. Green tea is, like many another type in general and gree...

OBJECTIVE The aim of this study was to compare the surgical outcomes of single-port access (SPA) and conventional multi-port access total laparoscopic hysterectomies (TLH) among patients with very large uteri (500 g or more). METHODS Fifty consecutive patients who received TLH for large uterine myomas and/or adenomyoses weighing 500 g or more between February 2009 and December 2012 were retro...

The present study was aimed to evaluate the effects of tea and olive leaves extracts and their combination in male mice intoxicated with a sublethal concentration of diazinon. Exposure of mice to 6.5 mg/kg body weight of diazinon for seven weeks resulted in statistical increases of serum alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, alkaline phosphatase, crea...

This paper reports on the application of total luminescence spectroscopy to discriminate between seven different types of tea. Bottled liquid teas; Oolong tea, Green tea, Houji tea, Japanese black tea and tea leaves (Kenya tea, Assam tea and Ceylon tea). Total luminescence spectra were recorded by measuring the emission spectra in the range 300nm to 700 nm at excitation wavelengths from 250 nm ...

The cyanoglycoside, prunasin, was isolated for the first time as an aroma precursor of benzaldehyde from fresh tea leaves (Camellia sinensis var. sinensis cv. Yabukita). Prunasin was readily hydrolyzed by a crude enzyme prepared from the fresh tea leaves to liberate benzaldehyde. The isomerization of prunasin under neutral conditions was also recognized.

Three types of Cocoa tea, green, oolong, and black, were prepared from fresh young leaves of Camellia ptilophylla. Their aroma characteristics were compared by a sensory evaluation with corresponding traditional tea samples made from C. sinensis. The aroma profile of Cocoa green tea was quite different from that of traditional green tea, but fermented Cocoa oolong tea and black tea showed aroma...

An electronic nose (E-nose) was employed to detect the aroma of green tea after different storage times. Longjing green tea dry leaves, beverages and residues were detected with an E-nose, respectively. In order to decrease the data dimensionality and optimize the feature vector, the E-nose sensor response data were analyzed by principal components analysis (PCA) and the five main principal com...
