Tea, coffee, and caffeinated beverage consumption and risk of epithelial ovarian cancers
Conclusion Black tea consumption may be associated with an increased risk epithelial ovarian carcinoma. The excess risk is seen only in the endometrioid histotype but not in serous or clear cell. Further studies are required to confirm these findings and identify the constituents in black tea that may increase the risk. (Source: Cancer Epidemiology)

Blood pressure is associated with tea consumption: A cross-sectional study in a rural, elderly population of Jiangsu China
ConclusionHabitual tea consumption was found to be associated with lower values of components of BP and a reduced likelihood of having hypertension in older adults. Given the widespread consumption of tea throughout China and the world, together with the major cardiovascular disease risk, our findings have important implications for human health.

The Effect of Polyhexanide, Octenidine Dihydrochloride, and Tea Tree Oil as Topical Antiseptic Agents on In Vivo Microcirculation of the Human Skin: A Noninvasive Quantitative Analysis.
CONCLUSION: Perfusion is an important factor for wound healing. Therefore, it might be advantageous if antiseptic agents would increase blood flow. Tea tree oil and polyhexanide have a positive effect on skin blood flow and can therefore be used especially in critically perfused wounds, provided the adverse reactions and the antimicrobial efficacy are comparable.

Molecules, Vol. 21, Pages 1379: Transcriptome Profile Reveals that Pu-Erh Tea Represses the Expression of Vitellogenin Family to Reduce Fat Accumulation in Caenorhabditis elegans
In conclusion, our transcriptional profile by RNA-Sequence suggests that Pu-erh tea lowers the fat accumulation primarily through repression of the expression of vit(vitellogenin) family, in addition to our previously reported (sterol regulatory element binding protein) SREBP-SCD (stearoyl-CoA desaturase) axis.

Interactions between α-amylase and an acidic branched polysaccharide from green tea.
Abstract
To understand the mechanism responsible for the α-amylase inhibitory activity of tea polysaccharides, the interaction between α-amylase and an acidic branched tea polysaccharide (TPSA) was investigated using fluorescence spectroscopy and resonance light scattering analysis. TPSA, exhibiting inhibitory activity towards α-amylase (the maximum inhibition percentage of 65%), was isolated from green tea (Camellia sinensis) and characterized by nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, and gas chromatography. Synchronous fluore...

The Combination of Green Tea Extract and Eriodictyol Inhibited High-Fat/High-Sucrose Diet-Induced Cholesterol Upregulation Is Accompanied by Suppression of Cholesterol Synthesis Enzymes.
Authors: Yamashita M, Kumazoe M, Nakamura Y, Won YS, Bae J, Yamashita S, Tachibana H
Abstract
Western diets induce obesity associated with an increased risk of hypercholesterolaemia. Indeed, obesity-induced hypercholesterolaemia is correlated with increased coronary cardiovascular disease (CVD) risk. Male C57BL/6J mice were fed a normal diet, high-fat and high-sucrose diet (HF/HS), HF/HS with green tea extract powder diet (HF/HS+GT), HF/HS with eriodictyol diet (HF/HS+Eri), or HF/HS with green tea extract powder and eriodictyol diet (HF/HS+GT+Eri) for 8 wk. Body weight was lower in the HF/HS+GT+Eri group t...

Evaluating the "Tape Tea" Myth as Low Cost Abuse Drug through Mass Spectrometry
The role of the "tape tea" as a low cost abuse drug is evaluated, by searching for possible inorganic and organic compounds after its preparation. Two energy sources are evaluated (conventional and microwave heating) for preparing the "tape tea" using new or used cassette (K7) or video home system (VHS) tapes. After optimizing all the inductively coupled plasma mass spectrometry (ICP-MS) conditions, the remarkable presence of Mn and Co, as well as Cr and Ni, at concentrations higher than 5 times those allowed for drinking water, makes the use of the "tape tea" plausible as a non-cost abuse drug due to some possible neuroto...

Bio-tea prevents membrane destabilization during isoproterenol-induced myocardial injury
Publication date: Available online 26 September 2016 Source:Journal of Microscopy and Ultrastructure Author(s): Reema Orison Lobo, K. Chandrakala Shenoy The present study was undertaken to determine the membrane-stabilizing effect of Bio-tea in the prevention of myocardial injury caused by isoproterenol in rats. The efficiency of Bio-tea pretreatment was compared against black tea pretreatment and the positive control (rats with isoproterenol-induced myocardial infarction) and negative control (normal control rats). For this purpose, biochemical analysis of the in vivo antioxidants (superoxide dismutase, catalase, and ...

Greener approach for synthesis of monodispersed palladium nanoparticles using aqueous extract of green tea and their catalytic activity for the Suzuki –Miyaura coupling reaction and the reduction of nitroarenes
A facile and green route for the synthesis of palladium nanoparticles (NPs) was developed utilizing non‐toxic and renewable natural green tea extract as the reducing, stabilizing and capping agent. The as‐prepared Pd‐NPs@G.Tea extract was characterized using UV–visible spectroscopy, X‐ray diffraction, Fourier transform infrared spectroscopy, field‐emission scanning electron microscopy, transmission electron microscopy and energy‐dispersive X‐ray spectroscopy. The Pd‐NPs@G.Tea extract could be used as an efficient and heterogeneous catalyst for Suzuki coupling reactions between phenylboronic acid and a ran...

Three-dimensional spatial variability in soil microorganisms of nitrification and denitrification at a row-transect scale in a tea field
In this study, three-dimensional (3D) geostatistics was applied at a tea row-transect scale to investigate the spatial distributions of N2O producers (ammonia oxidizers: AOA and AOB, denitrifiers: narG-type and nosZ-type) in a tea field in southern China. Our results showed that most of AOA, AOB, and denitrifiers of narG-type and nosZ-type concentrated in the topsoil at 0–20 cm. Soil depth was found a main factor to influence the spatial distributions of nitrifiers and denitrifiers, which were well-described by a Boltzmann sigmoidal equation with half-maximum coefficients ranging from 7 to 16 cm. Effective spatial rang...

A novel curcuminoid ‐tea polyphenol formulation: Preparation, characterization, and in vitro anti‐cancer activity
Abstract
Curcuminoids and tea polyphenols (CTP) are nutraceuticals with anticancer activity. To evaluate their combined in vitro anti‐cancer activity, the CTP mixture was loaded on solid lipid nanoparticles (SLNPs). The resulting CTP‐SLNPs were characterized and shown to have good chemical stability, making them suitable for delivery to cancer cells. A validated HPLC‐MS method was developed to monitor the composition and quality of the prepared CTP‐SLNP formulation, by identifying and quantifying its eight main components (epigallocatechin, epicatechin, catechin, epigallocatechingallate, epicatechingallate, curcumi...
