Synthesis, Characterization and Magnetic Studies of Dysprosium Complex, [Dy 2 (TEA) 2 (O 2 CPh) 4 ·2H 2 O]
AbstractA dysprosium complex, [Dy2 (TEA)2(O2CPh)4·2H2O] has been synthesized using TEA (tri-ethanolamine) and benzoic acid. The obtained complex is a dimer in which both of the TEA is linked with two dysprosium ions through the protonated oxygen atoms and the resultant molecule is Centro symmetric. The nature of bonding and structure of the synthesized dimer was explored from infrared, magnetic studies and single crystal X-ray crystallographic technique. The crystal structure of the complex has triclinic crystal system andP-1 space group. Unit cell parameters are: a = 10.0931(4) Å, b = 10.8841(5) Å, c = 10....

Pharmacological properties of agarwood tea derived from Aquilaria (Thymelaeaceae) leaves: an emerging contemporary herbal drink
Publication date: Available online 27 June 2017 Source:Journal of Herbal Medicine Author(s): Aimi Zafirah Adam, Shiou Yih Lee, Rozi Mohamed Agarwood tea is made from the leaves of Aquilaria, a protected tree species of the tropical forest. Trees in this genus produce agarwood, a highly-prized resin-impregnated wood formed in the main stem. The last decade has seen a steady expansion in Aquilaria plantation establishment. The popular plantation species are Aquilaria crassna, A. malaccensis, and A. sinensis. Farmers capitalized on the leaves of their planted Aquilaria tree by producing a tea drink, and thus the name ‘...

The use of ultrasound-assisted anaerobic compost tea washing to remove poly-chlorinated dibenzo-p-dioxins (PCDDs), dibenzo-furans (PCDFs) from highly contaminated field soils.
This study represents the first to report the use of anaerobic compost tea solvent to wash soil highly contaminated by dioxin. It was concluded that anaerobic compost tea, rich in non-toxic bio-surfactants (e.g., alcohols, humic acids), can be used to improve bioavailability and bioactivity of the soil making bio-attenuation and full remediation more efficient.

Effect of tolbutamide on TEA-induced postsynaptic zinc signals at hippocampal mossy fiber-CA3 synapses.
Abstract
The application of tetraethylammonium (TEA), a blocker of voltage-dependent potassium channels, can induce long-term potentiation in the synaptic systems CA3 - CA1 and mossy fibers - CA3 pyramidal cells of the hippocampus. In the mossy fibers the depolarization evoked by extracellular TEA induces a large amount of glutamate and also of zinc release. It is considered that zinc has a neuromodulatory role at the mossy fiber synapses, which can, at least in part, be due to the activation of presynaptic ATP-dependent potassium (KATP) channels. The aim of this work was to study properties of TEA-induced...

Molecules, Vol. 22, Pages 1061: Magnetic Solid-phase Extraction with Fe3O4/Molecularly Imprinted Polymers Modified by Deep Eutectic Solvents and Ionic Liquids for the Rapid Purification of Alkaloid Isomers (Theobromine and Theophylline) from Green Tea
Different kinds of deep eutectic solvents (DES) based on choline chloride (ChCl) and ionic liquids (ILs) based on 1-methylimidazole were used to modify Fe3O4/molecularly imprinted polymers (Fe3O4/MIPs), and the resulting materials were applied for the rapid purification of alkaloid isomers (theobromine and theophylline) from green tea with magnetic solid-phase extraction (M-SPE). The M-SPE procedure was optimized using the response surface methodology (RSM) to analyze the maximum conditions. The materials were characterized by Fourier transform infrared spectroscopy (FI-IR) and field emission scanning electron microscopy (...

Safety assessment of green tea based beverages and dried green tea extracts as nutritional supplements.
Abstract
The safety of green tea infusions and green tea extract (GTE)-based products is reviewed regarding catechins. Epigallocatechin 3-gallate (EGCG), the major catechin present in green tea, is suspected of being responsible for liver toxicity reported in humans consuming food supplements. Intake of EGCG with green tea infusions and GTE-based beverages is up to about 450mg EGCG/person/day in Europe and higher in Asia. Consumption of green tea is not associated with liver damage in humans, and green tea infusion and GTE-based beverages are considered safe in the range of historical uses. In animal studi...

Tea consumption is associated with cognitive impairment in older Chinese adults.
CONCLUSION: Habitual tea consumption is suggested to be associated with a decreased risk of CoI among elders in Suzhou, and a higher frequency of tea consumption was associated with a lower prevalence of CoI among never smokers.

Effects of Kaolin (M-99-099) Application on Antioxidant and Phenolic Compounds in Tea Leaves (Camellia sinensis L.O. Kuntze).
In this study, the effects of kaolin (M-99-099) applications on the total phenolic and antioxidant contents of tea leaves (Camellia sinensis (L.) O. Kuntze) harvested in three different periods were investigated. For this purpose, four different strategies including standard fertilizer application (T), 3% kaolin+standard fertilizer application (Ka1), 6% kaolin+standard fertilizer application (Ka2), and control (C) (nothing applied) were used to compare the effects of these strategies on total phenolic content, FRAP values, and DPPH radical scavenging capacities of tea leaves. It has been proven that the kaolin applications...

Synergistic effects and related bioactive mechanisms of Potentilla fruticosa Linn. leaves combined with green tea polyphenols studied with microbial test system (MTS).
This study further confirmed the synergy of PFE + GTP viewed from bioactivities using the microbial test system (MTS). The MTS antioxidant activity results showed the combination of PFE + GTP exhibited synergistic effect and the ratio 3:1 showed the strongest synergy, which were in accordance with the results in H2O2 production rate. The combination of PFE + GTP promoted CAT and SOD enzyme activity and their gene expression especially at the ratio 3:1. Therefore, the synergism of PFE + GTP may be due to the promotion of CAT and SOD genes expression which enhanced the CAT and SOD enzyme activities. These results con...

Comparison of Nutritional Composition, Aroma Compounds, and Biological Activities of Two Kinds of Tartary Buckwheat Tea
Abstract
Tartary buckwheat tea (TBT) is becoming increasingly popular for its unique flavor and health benefits. However, there is little information regarding the differences in nutritional quality among different kinds of TBT. Two kinds of TBT samples, whole grain tea (WGT) and whole plant tea (WPT), were collected from markets in China. The content of their nutritional compositions, including protein, amino acids, starch, fat, fatty acids, and flavonoids, as well as aroma compounds, were determined. Antioxidant and α‐glucosidase inhibitory activities were also evaluated. WPT showed higher levels of protein and fat re...

Tea Polyphenol inhibits autophagy to sensitize Epirubicin-induced apoptosis in human bladder cancer cells.
Abstract
Resistance to anticancer agents such as Epirubicin (EPI) becomes a great challenge for treating bladder cancer. However, the mechanism by which chemoresistance arised is still elusive. In the present study, we showed evidence that EPI induced cytoprotective autophagy in bladder cancer cell lines T24 and BIU87. In addition, EPI robustly activated JNK-mediated phosphorylation of Bcl-2 and disruption of Bcl-2/Beclin-1 complex. Furthermore, the green tea derivative tea polyphenol (TP) inhibited EPI-induced autophagy and promoted apoptosis induced by EPI in bladder cancer cells. These results revealed ...
