Supplementation with Brazil nuts and green tea extract regulates targeted biomarkers related to colorectal cancer risk in humans.
In conclusion, supplementation of Brazil nuts and/or GTE regulates targeted biomarkers related to CRC oncogenesis, specifically genes associated with selenoproteins (SePP), WNT signalling (β-catenin), inflammation (NF-κB) and methylation (DNMT1). Their combination does not appear to provide additional effects compared with either agent alone.

The Effect of Black Tea (Camellia sinensis (L) Kuntze) on Pediatrics With Acute Nonbacterial Diarrhea: A Randomized Controlled Trial
We aimed to evaluate the antidiarrheal effect of black tea in pediatric patients with acute nonbacterial diarrhea. This single-blind randomized clinical trial study was performed on 2 to 12-year-old patients, with acceptable criteria for acute nonbacterial diarrhea in Shiraz, Iran. In total, 120 patients took part in this study. Blocked randomization method was used to allocate them into 2 groups of intervention (black tea tablet + standard treatment) and control group (standard treatment; 60 patients in each). Frequency of defecation, volume, and consistency of stool were registered on arrival and 24 hours later. We used ...

The broadly tuned odorant receptor OR1A1 is highly selective for 3-methyl-2,4-nonanedione, a key food odorant in aged wines, tea, and other foods.
Abstract
Key food odorants are the most relevant determinants by which we detect, recognize, and hedonically evaluate the aroma of foods and beverages. Odorants are detected by our chemical sense of olfaction, comprising a set of approximately 400 different odorant receptor types. However, the specific receptor activity patterns representing the aroma percepts of foods or beverages, as well as the key food odorant agonist profiles of single-odorant receptors, are largely unknown. We aimed to establish comprehensive key food odorant agonist profiles of 2 unrelated, broadly tuned receptors, OR1A1 and OR2W1, ...

Molecules, Vol. 21, Pages 1622: In Vitro Chemopreventive Properties of Green Tea, Rooibos and Honeybush Extracts in Skin Cells
The chemopreventive properties of the herbal teas rooibos (Aspalathus linearis) and honeybush (Cyclopia spp.) have been demonstrated on mouse skin in vivo but the underlying mechanisms are not clear. The aim of the current study was to determine the anti-proliferative and pro-apoptotic activity of methanol and aqueous extracts of rooibos and two Cyclopia species in different skin cells, using green tea (Camellia sinensis) as a benchmark. Extracts were also characterised for their major individual polyphenols by high performance liquid chromatography and spectroscopically for the total polyphenol (TP) groups. The methanol e...

Molecules, Vol. 21, Pages 1566: Biophysical Approach to Mechanisms of Cancer Prevention and Treatment with Green Tea Catechins
Green tea catechin and green tea extract are now recognized as non-toxic cancer preventives for humans. We first review our brief historical development of green tea cancer prevention. Based on exciting evidence that green tea catechin, ( −)-epigallocatechin gallate (EGCG) in drinking water inhibited lung metastasis of B16 melanoma cells, we and other researchers have studied the inhibitory mechanisms of metastasis with green tea catechins using biomechanical tools, atomic force microscopy (AFM) and microfluidic optical stretcher. Specifically, determination of biophysical properties of cancer cells, low cell stiffness, ...

Determination of pesticide and phthalate residues in tea by QuEChERS method and their fate in processing.
In this study, the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method was applied for the analysis of the multiclass pesticide residues of 12 organochlorines (OCs), 9 organophosphates (OPs), 11 synthetic pyrethroids (SPs), 4 herbicides, 6 phthalates in raw tea (loose tea, branded tea and herbal tea), and tea infusion in 4 different containers (glass cup, earthen cup, plastic bag and disposal cup). In loose tea and branded tea residues, malathion (0.257 and 0.118 mg kg(-1)), cypermethrin (0.065 and 0.030 mg kg(-1)), and fenvalerate (0.032 and 0.030 mg kg(-1)) were detected, respectively. In herbal tea, ...

In-syringe dispersive liquid-liquid microextraction based on the solidification of ionic liquids for the determination of benzoylurea insecticides in water and tea beverage samples.
Abstract
A novel in-syringe dispersive liquid-liquid microextraction based on the solidification of ionic liquids (in-syringe SIL-DLLME) was coupled with high-performance liquid chromatography-ultraviolet detector (HPLC-UVD) to detect five benzoylurea insecticides (BUs) in water and tea beverage samples. In this method, the hydrophobic ionic liquid [N8881][PF6] was formed in situ by the metathesis reaction between [N8881]Cl and the anion-exchange reagent KPF6 to extract the target analytes. The whole extraction procedure was performed in a syringe. The solidified extractant could be separated from the aque...

In vitro assay to estimate tea astringency via observing flotation of artificial oil bodies sheltered by caleosin fused with histatin 3
Publication date: Available online 5 November 2016 Source:Journal of Food and Drug Analysis Author(s): Yu-En Shih, Yu-Chih Lin, Tse-yu Chung, Mei-Chun Liu, Guan-Heng Chen, Chia-Chang Wu, Jason T.C. Tzen Astringency, a sensory characteristic of food and beverages rich in polyphenols, mainly results from the formation of complexes between polyphenols and salivary proteins, causing a reduction of the lubricating properties of saliva. To develop an in vitro assay to estimate the astringency of oolong tea infusion, artificial oil bodies were constituted with sesame oil sheltered by a modified caleosin fused with hista...

Molecules, Vol. 21, Pages 1449: Tea Polysaccharides and Their Bioactivities
Tea (Camellia sinensis) is a beverage beneficial to health and is also a source for extracting bioactive components such as theanine, tea polyphenols (TPP) and tea polysaccharides (TPS). TPS is a group of heteropolysaccharides bound with proteins. There is evidence showing that TPS not only improves immunity but also has various bioactivities, such as antioxidant, antitumor, antihyperglycemia, and anti-inflammation. However, inconsistent results concerning chemical composition and bioactivity of TPS have been published in recent years. The advances in chemical composition and bioactivities of TPS are reviewed in the presen...

Correlation Between Tea Consumption and Prevalence of Hypertension Among Singaporean Chinese Residents Over 40
In Singapore, the prevalence of hypertension increased markedly from age 40 years onwards. Tea has been approved to possess many beneficial pharmacological effects including antihypertension. However, no clinical studies on drinking tea and hypertension among Singaporeans have been conducted. We are the first to investigate the correlation of hypertension and consumption of tea, health supplements, living habits and socio-demographic factors among Singaporean Chinese residents.

Antioxidant properties of tea blunt ROS-dependent lipogenesis: beneficial effect on hepatic steatosis in a high fat-high sucrose diet NAFLD obese rat model
Oxidative stress could trigger lipid accumulation in liver and thus hepatic steatosis. Tea is able to prevent liver disorders but a direct link between antioxidant capacities and prevention of steatosis has not been reported yet. We aimed to investigate such relationship in a rat model of high fat-high sucrose diet (HFS)-induced obesity and to explore more deeply the mechanisms in isolated hepatocytes. Wistar rats were divided into a Control group (standard diet), a HFS group (high fat-sucrose diet) and a HFS+Tea group (HFS diet with ad-libitum access to tea drink).
