Full textAbstract:
Green tea (Camellia sinensis) catechin profiles in plasma and urine following single dosing and regular ingestion of green tea are not clear. We performed a placebo-controlled intervention study with sixteen healthy volunteers to determine changes in total and free catechins after a single dose and following 1 week of twice-daily green tea. Blood and urine samples were collected before (fasting) and after (60 and 120 min for blood; 90 and 180 min for urine) drinking 200 ml of 1·5 % (w/v) green tea or water (n 8 each), and fasting samples were again collected after 7 d of 150 ml of 1 % (w/v) supplemental green tea or water twice daily. After a 4-week washout, subjects were crossed onto the other treatment and procedures repeated. Plasma results at 1 h post-ingestion showed elevated (P< 0·05) mean epigallocatechin gallate (EGCG; 310 (sd 117) nmol/l; all in free form), epigallocatechin (EGC; 192 (sd 67) nmol/l; 30 % free) and epicatechin gallate (ECG; 134 (sd 51) nmol/l; 75 % free). Fasting plasma after 7 d of regular intake showed increased (P< 0·05) EGCG (80 v. 15 nmol/l at baseline) and ECG (120 v. 40 nmol/l), with ≥ 90 % of both in their conjugated forms. Total EGC was < 10 nmol/l. Post-ingestion conjugation and renal loss of EGC and epicatechin were rapid and high, but were negligible for EGCG and ECG. In the green tea consumed, the content was EGCG >EGC >ECG, and the acute plasma response mirrored this. However, after chronic consumption there was almost no EGC found in fasting plasma, some EGCG was present, but a rather high level of ECG was maintained.

Full textAbstract:
The effect of epigallocatechin gallate (EGCG) on cell survival was studied by using serum-starved A549 non-small cell lung carcinoma (NSCLC) cells. A MTT assay showed that EGCG significantly increased the viability of serum-starved A549 cells compared to the control cells, though EGCG at high concentration (~300 μM) had no protective effect against serum withdrawal-induced cell apoptosis. Western blots showed increased immunoreactivity for phospho-Akt and phospho-GSK3β in EGCG-treated cells. To determine the mechanism for Akt phosphorylation, cells were pretreated with various kinase inhibitors before exposure to EGCG. Only LY294002 inhibited Akt activation induced by EGCG, implying that EGCG-induced Akt activation is PI3K dependent. Both phospho-Raf-1 and Raf-1 proteins were significantly decreased, whereas B-raf expression was not altered. This suggests that the Raf kinases have no role in the increased cell survival caused by EGCG. This study has shown that EGCG protects A549 cells from apoptosis induced by serum deprivation via Akt activation and this protective effect may limit the clinical use of EGCG in treating and preventing NSCLC.

Full textAbstract:
Nanoparticles based on chitosan modified with epigallocatechin gallate (EGCG) were synthetized by nanoprecipitation (EGCG-g-chitosan-P). Chitosan was modified by free-radical-induced grafting, which was verified by Fourier transform infrared (FTIR). Furthermore, the morphology, particle size, polydispersity index, and zeta potential of the nanoparticles were investigated. The grafting degree of EGCG, reactive oxygen species (ROS) production, antibacterial and antioxidant activities of EGCG-g-chitosan-P were evaluated and compared with those of pure EGCG and chitosan nanoparticles (Chitosan-P). FTIR results confirmed the modification of the chitosan with EGCG. The EGCG-g-chitosan-P showed spherical shapes and smoother surfaces than those of Chitosan-P. EGCG content of the grafted chitosan nanoparticles was 330 μg/g. Minimal inhibitory concentration (MIC) of EGCG-g-chitosan-P (15.6 μg/mL) was lower than Chitosan-P (31.2 μg/mL) and EGCG (500 μg/mL) against Pseudomonas fluorescens (p < 0.05). Additionally, EGCG-g-chitosan-P and Chitosan-P presented higher Staphylococcus aureus growth inhibition (100%) than EGCG at the lowest concentration tested. The nanoparticles produced an increase of ROS (p < 0.05) in both bacterial species assayed. Furthermore, EGCG-g-chitosan-P exhibited higher antioxidant activity than that of Chitosan-P (p < 0.05) in 2,2′-azino-bis (3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and ferric-reducing antioxidant power assays. Based on the above results, EGCG-g-chitosan-P shows the potential for food packaging and biomedical applications.

The aim of the present study was to examine the effects of green tea epigallocatechin-3-gallate (EGCG) on changes in body composition, energy and substrate metabolism, cardiometabolic risk factors and liver function enzymes after an energy-restricted diet intervention in obese women. In the present randomised, double-blind, placebo-controlled study, eighty-three obese (30 kg/m2>BMI < 40 kg/m2) pre-menopausal women consumed 300 mg/d of EGCG or placebo (lactose). We measured body weight and adiposity (dual-energy X-ray absorptiometry), energy expenditure and fat oxidation rates (indirect calorimetry), blood lipid levels (TAG, total cholesterol, LDL-cholesterol and HDL-cholesterol), insulin resistance, C-reactive protein and liver function markers (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamyltransferase, urea, bilirubin and 2-keto[1-13C]isocaproate oxidation) before and after the intervention in the EGCG and control groups. We did not find any significant difference in the changes in body weight ( − 0·3 kg, 95 % CI − 5·0, 4·3), fat mass ( − 0·7 kg, 95 % CI − 3·5, 2·1), energy (0·3 kJ/kg per d, 95 % CI − 3·1, 2·7) and fat ( − 0·1 g/min, 95 % CI − 0·03, 0·01) metabolism, homeostasis assessment model for insulin resistance (0·2, 95 % CI − 0·2, 0·7), total cholesterol ( − 0·21 mmol/l, 95 % CI − 0·55, 0·13), LDL-cholesterol ( − 0·15 mmol/l, 95 % CI − 0·50, 0·20), TAG ( − 0·14 mmol/l, 95 % CI − 0·56, 0·29) and liver function markers between the EGCG and control groups. In conclusion, the present results suggest that dietary supplementation with 300 mg/d of EGCG for 12 weeks did not enhance energy-restricted diet-induced adiposity reductions, and did not improve weight-loss-induced changes in cardiometabolic risk factors in obese Caucasian women. The intake of 300 mg/d of EGCG for 12 weeks did not cause any adverse effect on liver function biomarkers.

Full textAbstract:
It has been reported that green tea has a thermogenic effect, due to its caffeine content and probably also to the catechin, epigallocatechin-3-gallate (EGCG). The main aim of the present study was to compare the effect of a mixture of green tea and Guarana extracts containing a fixed dose of caffeine and variable doses of EGCG on 24 h energy expenditure and fat oxidation. Fourteen subjects took part to this randomized, placebo-controlled, double-blind, cross-over study. Each subject was tested five times in a metabolic chamber to measure 24 h energy expenditure, substrate oxidation and blood pressure. During each stay, the subjects ingested a capsule of placebo or capsules containing 200 mg caffeine and a variable dose of EGCG (90, 200, 300 or 400 mg) three times daily, 30 min before standardized meals. Twenty-four hour energy expenditure increased significantly by about 750 kJ with all EGCG–caffeine mixtures compared with placebo. No effect of the EGCG–caffeine mixture was observed for lipid oxidation. Systolic and diastolic blood pressure increased by about 7 and 5 mmHg, respectively, with the EGCG–caffeine mixtures compared with placebo. This increase was significant only for 24 h diastolic blood pressure. The main finding of the study was the increase in 24 h energy expenditure with the EGCG–caffeine mixtures. However, this increase was similar with all doses of EGCG in the mixtures.

Full textAbstract:
Purpose The epigallocatechin gallate (EGCG) effect in diabetes has been investigated in animal studies, but results of clinical trials are inconsistent. Thus, this study aims to evaluate the effects of EGCG supplementation in patients with type 2 diabetes mellitus (T2DM). Design/methodology/approach A total of 50 patients with T2DM were recruited in a double-blind, randomized, placebo-controlled trial. The eligible participants were randomly allocated to EGCG (n = 25) and placebo (n = 25) groups. The EGCG group received two capsules of EGCG (each capsule contained 150 mg; Shari Made®, Iran) and placebo group was administered two capsules of placebo (starch) for eight weeks. A three-day 24-h dietary recall and anthropometric and laboratory measurements were carried out at the beginning and the end of the study. Findings At the end of the trial, weight and body mass index (BMI) were decreased significantly in both groups, but the reduction was not statistically significant between the two groups. Fasting blood sugar decreased significantly in EGCG group. No significant between-group and within-group differences were found in insulin, homeostatic model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index values. The high-sensitive C-reactive protein (hs-CRP) was significantly reduced in the EGCG group (4.13 ± 0.48-3.93 ± 0.50, p = 0.003) compared to baseline. Originality/value This study showed that consuming 300 mg/day of EGCG for eight weeks in patients with T2DM caused a significant decrease in fasting blood glucose, body weight, BMI and hs-CRP compared to baseline. Therefore, the EGCG supplementation may improve glycemic control, anthropometric and inflammation status in T2DM.

Coville (Fabaceae) proanthocyanidins quantitation by RP-HPLC." Brazilian Journal of Pharmaceutical Sciences 49, no. 3 (2013): 549–58. http://dx.doi.org/10.1590/s1984-82502013000300016.
Full textAbstract:
Stryphnodendron adstringens (Mart.) Coville (barbatimão) is a tree belonging to the Fabaceae family, and it is commonly found in the southeastern Brazilian cerrado. The stem bark of this tree is traditionally used as an anti-inflammatory and antiseptic agent to treat leucorrhea and diarrhea, as well as to promote wound healing (owing to the presence of proanthocyanidins). Proanthocyanidins were obtained from the ethanolic extract of S. adstringens stem bark and assessed by reversed phase-high performance liquid chromatography with an ultraviolet/diode array detector. The identified compounds included gallic acid, catechin, gallocatechin (GC), epigallocatechin, and epigallocatechin gallate (EGCG). The selected markers, GC and EGCG, were simultaneously used for chromatographic validation (linearity range: 30-330 ng, equivalent to 3-33 µg/mL; r>0.998). The method showed precision (intra-day relative standard deviation [RSD]: 1.72% for GC; 1.16% for EGCG; inter-day RSD: 1.74%-2.60% for both markers), accuracy, robustness, and selectivity. The limits of detection and quantitation were 0.29 µg/ml and 0.89 µg/ml for GC, and 0.88 µg/mL and 2.67 µg/mL for EGCG, respectively. In addition, S. obovatum was evaluated and showed an average of 12.2 µg/mL for GC (equivalent to 1.22% w/w) and 14.2 µg/mL for EGCG (equivalent to 1.42% w/w) in the ethanolic extract. The quantitative results were compared to those obtained for S. adstringens, which showed that the markers are present in both species.

The aim of the present study was to investigate the co-effect produced by water-soluble form of quercetin and epigallocatechin-3-gallate (EGCG) on biochemical markers of periodontal organic matrix depolimerization under systemic administration and local application of S. typhi lipopolisaccharide (LPS). The studies were conducted on 30 white rats of the Wistar line weighing 180-220 g, divided into 5 groups: the 1st included intact animals, the 2nd was made up of animals after the combined systemic and local LPS administration, the 3rd and 4th groups included animals, which were being given injections with water-soluble form of quercetin (10 mg / kg) and EGCG (21.1 mg / kg) respectively 3 times a week, starting on the 30th day of the systemic LPS administration, and the 5th group involved rats, which were injected with co-administered water-soluble form of quercetin and EGCG. It has been found out that the co-effect produced by quercetin and EGCG under systemic and local LPS administration is accompanied with reduced concentration of N-acetylneuraminic acid (NANA) by 31.8 and 32.8% respectively in the soft periodontal tissues compared with values for the animals received separate quercetin and EGCG during the experiment. However, no differences have been detected between the groups exposed to combined or separate action of the above mentioned agents in the experiment when assessing free hydroxyproline (FHP) and glycosaminoglycans (GAGs) content in the soft tissues of periodontium. At the same time combined use of quercetin and EGCG under experimental conditions led to the decrease in the FHP content in the alveolar bone by 24.5 and 20.2% respectively compared with values for the animals received separate quercetin and EGCG. NANA concentration was reduced by 35.0 and 41.3% respectively. Thus, the co-administration of water-soluble form of quercetin and epigallocatechin-3-gallate under systemic and local introducing of S. typhi lipopolysaccharide has been proven to be more effective means for preventing and correcting periodontal connective tissue disruption than this occurs at separate administration of each of the polyphenols.

Abstract Abstract 3452 Poster Board III-340 PURPOSE Chronic Lymphocytic Leukemia (CLL) is incurable with current chemotherapy treatments. Epigallocatechin 3 gallate (EGCG), the major catechin in green tea, has been shown to induced caspase-dependent death CLL B-cells and down regulate anti-apoptotic proteins (Mcl-1; XIAP) known to increase the resistance of CLL B-cells to apoptosis (Blood 104:788-94). In Phase I testing for patients with early stage CLL (Rai 0-II), EGCG treatment was well tolerated and induced a decline in absolute lymphocyte count (ALC) and/or lymphadenopathy in the majority of treated patients without myelosuppression (JCO 27:3808-14). Although peak plasma EGCG levels were not measured in this study, trough plasma EGCG levels as high as 4 μg/ML were achieved. To further our understanding of the potential clinical applications of EGCG for patients with CLL, we evaluated the effects of EGCG on the viability of CLL B-cells when combined with fludarabine (F), chlorambucil (C), or fludarabine and chlorambucil in combination (FC). METHODS Primary CLL B-cells were treated with various doses of F (0.25-1 μM), C (10-30 μM), or FC either alone or in combination EGCG (50 to 100 μM). In other experiments, CLL B-cells were treated with various doses of F (0.25-1 μM), C (10-30 μM), or FC with or without a fixed dose of EGCG known to be physiologically achievable in vivo (4 μM). After 48 hours (experiments with C +/− EGCG) or 72 hours (experiments with F +/− EGCG or FC +/− EGCG), cells were harvested, stained with annexin/PI and viability analyzed by flow cytometry. After concentration-effect curves were generated for each agent, data were also analyzed using the CalcuSyn software program (Biosoft, Cambridge, UK) which uses the method of Chou and Talalay to determine whether combination treatment yielded greater effects than expected from summation alone. A combination index (CI) of 0.8 – 1.2 indicates an additive effect, a CI >1.2 indicates an antagonistic effect and a CI <0.8 indicates a synergistic effect. RESULTS Primary leukemic B-cells from 56 CLL patients were cultured in vitro with various doses of EGCG alone or in combination with F, C, or FC. The median LD50 was approximately 100 μM. Although % apoptotic cells at the 100 μM EGCG dose did not vary based on Rai stage, ZAP-70 status, IGHV gene mutation status, or cytogenetic abnormalities by FISH, CD38 negative patients had greater cell death than CD38 positive patients (67% vs. 49%; p=0.05). In co-titration experiments, EGCG had an additive (CI 0.8 – 1.2) or synergistic (CI <0.8) effect on apoptosis when combined with C in the majority of patients (13/15; additive 11, synergism 2) with rare individuals demonstrating antagonism (CI >1.2; 2/15). The effects of EGCG when combined with F in co-titration experiments were more variable with a relatively even distribution between antagonism (8/18), additive effects (4/18), and synergy (6/18). However, co-titration experiments of FC with or without EGCG demonstrated additive or synergistic effect in most patients (8/10; additive 7, synergism 1). Next we evaluated the effect of F (0.25 - 1 μM), C (10 - 30 μM), or FC with or without a fixed dose of EGCG known to be physiologically achievable in vivo (4 μM). This dose of EGCG had an additive or synergistic effect in the majority of samples across the spectrum of dose levels under all 3 conditions (F, C, and FC). For example, at the 10 μM dose of C the addition of 4 μM EGCG had an additive or synergistic effect in 11/14 patients (synergistic 6; additive 5). With F at the 2.5 μM dose level the addition of 4 μM EGCG had an additive or synergistic effect in 13/16 patients (synergistic 7, additive 6). The addition of 4 μM EGCG appeared particularly beneficial when given in combination with FC (Fig.). For example, at F 2.5 μM in combination with C 5 μM the addition of 4 μM EGCG had an additive or synergistic effect in 10/10 patients (synergism 7; additive 3). CONCLUSIONS Physiologically achievable doses of EGCG appear to enhance the efficacy of alkylating agents, purine nucleoside analogues, and alkylating agent/purine analogue combination therapy for the majority of CLL patients on in vitro testing. The favorable toxicity profile of EGCG and lack of myelosuppression with this agent in the phase I trial (JCO 27:3808-14) make it an attractive agent to test in combination with purine analogue and alkylator based chemo-immunotherapy for patients with CLL.

Full textAbstract:
Shikimate dehydrogenase (AroE) is an attractive target for herbicides and antimicrobial agents due to its conserved and essential nature in plants, fungi, and bacteria. Here, we have performed an in vitro screen using a collection of more than 5500 compounds and identified 24 novel inhibitors of AroE from Pseudomonas putida. The IC50 values for the two most potent inhibitors we identified, epigallocatechin gallate (EGCG) and epicatechin gallate (ECG), were 3.0 ± 0.2 µM and 3.7 ± 0.5 µM, respectively. Based on the high level of structural conservation between AroE orthologs, we predicted that the identified compounds would also inhibit AroE enzymes from other organisms. Consistent with this hypothesis, we found that EGCG and ECG inhibit the AroE domain of the bifunctional dehydroquinate dehydratase-shikimate dehydrogenase (DHQ-SDH) from Arabidopsis thaliana with IC50 values of 2.1 ± 0.3 µM and 2.0 ± 0.2 µM, respectively.

L'objectif de cette thèse est d'évaluer différents chocs extérieurs et des réformes de politique commerciale sur une petite économie ouverte comme l'Uruguay, en mettant l’accent sur la compréhension des canaux de transmission des chocs vers la répartition des revenus et la pauvreté. Plus précisément, j'évalue deux chocs externes –la récente crise financière et une augmentation des prix alimentaires et pétroliers- et une réforme de politique commerciale: la négociation d'un accord de libre-échange entre le Mercosur et l'Union Européenne. Pour ce faire, j’applique différents modèles d'équilibre général (EGC): deux modèles statiques uni-pays et un modèle global dynamique, MIRAGE-HH, qui comprend une désagrégation des ménages. Les modèles EGC sont combinées avec des techniques de microsimulation: microsimulation non-paramétrique et méthode «micro-accounting». Comme les chocs extérieurs peuvent avoir un impact négatif sur la pauvreté en Uruguay, j’évalue aussi les options politiques visant à atténuer cet impact négatif. Les résultats montrent que les canaux de transmission des réformes de politique commerciale et des chocs extérieurs sont divers et complexes et ils peuvent avoir des effets opposés sur la pauvreté. Ils mettent également en évidence le fait que l'impact sur les différents groupes de population n'est pas uniforme. Dans certains cas, les chocs positifs sur l'économie peuvent encore nuire à des groupes de population. Dans la plupart des cas, les groupes affectés négativement sont les populations déjà vulnérables ayant peu de ressources pour faire face à ces chocs. Pour cette raison, il est important d'évaluer aussi des réponses politiques pour éviter cet impact négatif sur les pauvres<br>The aim of this dissertation is to evaluate different external shocks and trade policies on a small open economy such as Uruguay, making an emphasis in understanding the channels of transmission of the shocks to income distribution and poverty in the country. Specifically, I evaluate two external shocks –the recent financial crisis and an increase in food and oil prices- and one trade policy –the negotiation of a free trade agreement between MERCOSUR (conformed by Argentina, Brazil, Paraguay and Uruguay) and the European Union. For doing so, I apply different general equilibrium models: two different static single country models and one global dynamic model, MIRAGE-HH, which includes household disaggregation. The CGE models are combined with microsimulation techniques: non-parametric microsimulations and micro-accounting methods. Results show that the channels of transmission of trade policies and external shocks are diverse and complex and they may have opposite effects on welfare and poverty. They also highlight the fact that the impact on different population groups is not even. In some cases, positive shocks on the economy may still harm population groups. In most cases,iiithey are the already vulnerable population who count with fewer resources to counteract negative shocks. For this reason, it is important to also evaluate policy responses to prevent this negative impact on the poor

Cette thèse vise à étudier les liens entre les investissements publics, le mode definancement et la croissance économique, tout en mettant en exergue le rôle des conditionsstructurelles. Premièrement, dans un scenario d’amélioration des conditions structurelles(mesurées par l’efficience et la capacité d'absorption de l’économie) comparé à un scenario debase, nous montrons que le potentiel de croissance est supérieur comparé au scenario de base. Parconséquent, la stabilisation de la dette ne nécessite pas des ajustements budgétaires douloureux.Deuxièmement, à travers un scénario d'investissement agressif sur la base d’emprunts nonconcessionnelsen anticipation des revenus futurs du pétrole, nous constatons l’occurrence decontraintes liées à la capacité d'absorption et partant l’effet adverse du syndrome hollandais sur lacroissance du PIB hors pétrole. En outre, des réformes structurelles qui résorberaient lescontraintes liées à l’inefficience et à la capacité d'absorption se traduiraient par une augmentationimportante et durable du capital public. Cela entrainerait une croissance supplémentaire du PIBhors pétrole. Troisièmement, nous montrons que les délais d’exécution peuvent contrer l’effetclassique selon lequel une augmentation de l’investissement public entraine un effet richessenégatif dans le long terme. Aussi, une productivité élevée de l’investissement public peutsubstantiellement créer un effet richesse positif dans le long terme, stimuler la production etpermettre à la consommation et à l’investissement privé de baisser moins. Finalement, noussimulons l’impact des dépenses publiques d’éducation sur la pauvreté au Burkina Faso en utilisant2 mécanismes d’ajustement fiscal : la taxe directe et la taxe indirecte. Les simulations montrentqu’une augmentation uniforme de 40 pourcent des dépenses publiques dans l’éducation primairefiancée par les deux mécanismes de financement améliore non seulement le bien-être maiségalement entraine une baisse de la pauvreté chez tous les types de ménage. Toutefois, lefinancement par la taxe indirecte conduit à un résultat inférieur comparé au financement par lataxe directe<br>This dissertation seeks to study the public investment-financing-growth linkages whileeliciting the role of structural economic conditions. First, through an alternative scenario ofimproved structural economic conditions (efficiency and absorptive capacity) and comparing witha baseline scenario, we find that the growth potential is higher than the baseline. Consequently,stabilizing debt does not require painful fiscal consolidation. Second, through an aggressiveinvestment scaling-up scenario that builds on commercial borrowing in anticipation of future oilrevenue, we find that the economy is subject to absorptive capacity constraints and ultimately toDutch disease effects that affect negatively the non-oil GDP growth in the short run. Moreover,we find that structural reforms that address absorptive capacity constraints and inefficienciestranslate into sizable and sustainable increase in public capital. This in turn has a positive spillovereffect in terms of additional growth in the non-resource GDP. Third, we find that implementationdelays can offset the standard negative wealth effect from an increase in government investmentspending in the long run. Also, high-yielding public investment can substantially create positivewealth effect in the long run, raise output and enable private consumption and investment to fallless. Finally, we simulate a 40-percent across-the-board increase in public spending for primaryeducation, financed by an increase in taxes on household income and indirect taxes. We find thatthe two financing mechanisms, not only leads to an increase in the welfare but also to a decline inthe incidence of poverty for all household types. However, the indirect tax-based financing leadsto smaller outcomes compared to the income tax-based financing
