Tea, a beverage produced by steeping processed top leaves and buds of the tea plant in freshly boiled water, originated in China 2700 BC, but its medicinal properties were know much before that. China was the first country to cultivate tea. In Japan the cultivation began about 200 AD. The use of tea later spread to the other Asian countries. Tea cultivation in India was suggested as early as 17...

the potential of tobacco waste as a viable source of medicinally important flavonoids like rutin has been investigated. three flavonoids, apigenin, quercetin and rutin, have been isolated from waste tobacco leaves, and their identities have been confirmed by uv-visible, 1h-nmr and 13c-nmr spectroscopy. by using analytical hplc, the amount of rutin present in the tobacco leaves, before and after...

1-Phenylethanol (1PE) is a major aromatic volatile in tea (Camellia sinensis) flowers, whereas it occurs in a much smaller amounts in leaves. Enzymes involved in the formation of 1PE in plants and the reason why 1PE differentially accumulates in plants is unknown. In the present study, enzymes in the last step leading from acetophenone to 1PE were isolated from tea flowers by traditional bioche...

BACKGROUND AND PURPOSE Although experimental studies have suggested that tea consumption may reduce the risk of ischemic stroke, available epidemiological evidence is equivocal, mainly due to the lack of accurate measurements on tea exposure. This study aims to ascertain the relationship between tea drinking and ischemic stroke risk. METHODS A case-control study was conducted in southern Chin...

Objective: To compare the operative outcomes of total laparoscopic hysterectomy (TLH) and vaginal hysterectomy (VH) in a training and research hospital. Material and Methods: Retrospective data analysis of all women who underwent either TLH or VH at gynecology unit for benign pathologies between January, 2012 and June, 2015 were conducted. Hysterectomies for desensus uteri were excluded. Groups...

The flavor volatile compounds of dried red cashew flowers, cashew leaf-buds, cashew leaves and licorice roots as well as flavored herb teas were analyzed by gas chromatography-mass spectrophotometry (GC-MS). It was found that terpenes, including α-pinene, α-phellandrene and β-phellandrene were the main volatiles in the cashew leaf-buds and leaves. The major volatile compounds of the red cashew ...

To analyze and compare the safety and perioperative outcomes of newly trained robotic surgeons with previous laparoscopic hysterectomy experience (TLH Exp) and those without previous laparoscopic hysterectomy experience (Non-TLH Exp). The purpose is to determine the effect of previous advanced laparoscopic skills on the performance in robotic assisted laparoscopic surgery. We will also compare ...

OBJECTIVES To compare patient characteristics, operative variables, and outcomes of 24 patients who underwent robotic-assisted total laparoscopic hysterectomy (TLH) with 44 patients who underwent conventional TLH. We retrospectively reviewed the charts of 44 patients with TLH and 24 patients with robotic TLH. RESULTS Robotic TLH was associated with a shorter hospital stay (1.0 vs 1.4 days, P=...

The potential of tobacco waste as a viable source of medicinally important flavonoids like rutin has been investigated. Three flavonoids, apigenin, quercetin and rutin, have been isolated from waste tobacco leaves, and their identities have been confirmed by UV-visible, 1H-NMR and 13C-NMR spectroscopy. By using analytical HPLC, the amount of rutin present in the tobacco leaves, before and after...

Heavy metals released by a number of industrial processes are major pollutants in marine, ground, industrial and even treated waste waters. Biosorption is a process that utilizes biological materials as adsorbents and several researchers have studied this method as an alternative technique to conventional methods for heavy metal removal from wastewaters. In this study, the efficiency of tea was...
