Green tea has been an important beverage for humans since ancient times, widely consumed and considered to have health benefits by traditional medicine in Asian countries. Green tea phenolic compounds are predominately composed of catechin derivatives, although other compounds such as flavonols and phenolic acids are also present in lower proportion. The bioactivity exerted by these compounds has been associated with reduced risk of severe illnesses such as cancer, cardiovascular and neurodegenerative diseases. Particularly, epigallocatechin gallate has been implicated in alteration mechanisms with protective effect in these diseases as indicated by several studies about the effect of green tea consumption and mechanistic explanation through in vitro and in vivo experiments. The biological activity of green tea phenolic compounds also promotes a protective effect by antioxidant mechanisms in biological and food systems, preventing the oxidative damage by acting over either precursors or reactive species. Extraction of phenolic compounds influences the antioxidant activity and promotes adequate separation from green tea leaves to enhance the yield and/or antioxidant activity. Application of green tea phenolic compounds is of great interest because the antioxidant status of the products is enhanced and provides the product with additional antioxidant activity or reduces the undesirable changes of oxidative reactions while processing or storing *** this scenario, meat and meat products are greatly influenced by oxidative deterioration and microbial spoilage, leading to reduced shelf life. Green tea extracts rich in phenolic compounds have been applied to increase shelf life with comparable effect to synthetic compounds, commonly used by food industry. Green tea has great importance in general health in technological application, however more studies are necessary to elucidate the impact in pathways related to other diseases and food applications.

Objective: To evaluate the phenolic profile and antioxidant activity in vitro of peanut skin extract(PSE) and effect of PSE on characteristics of sheep patties during ***: PSE phenolic profile was evaluated in LC–MS analysis and by total phenolic content, 1,1-diphenyl-2-picrylhydrazyl radical scavenging capacity and ferric reducing/antioxidant power. Patties elaborated with sheep meat were packaged in modified atmosphere and storage at(2 ± 1)C. The analyses were performed every 5 days for 20 days on microbial counts, physico-chemical properties, lipid oxidation, protein stability and sensory ***: The major group of phenolic compounds in PSE was the proanthocyanidins followed by other flavonoids, which are related to potential phenolic content and antioxidant activity. The addition of PSE and butyl hydroxytoluene(BHT) reduced the microbial counts during the storage time, caused reduction on the loss of redness and sensory properties over time. The lipid and protein oxidation in sheep patties was effectively inhibited by PSE and ***: The present results showed the potential application of PSE as a natural alternative to replace synthetic antioxidants(BHT) for increasing the quality and extending the shelf-life of sheep patties.

Effect of genistein supplementation of thawing medium on characteristics of frozen human spermatozoa

引用

Asian Journal of Andrology 2010年第3期12卷 431-441,I0012页

作者： Juan Carlos Martinez-Soto Juan de DiosHourcade Alfonso Gutierrez-Adan jose lorenzo Landeras Joaquin Gadea Department of Physiology School of Veterinary Murcia University Murcia 30100 Spain IVI- MURCIA Murcia 30007 Spain Department of Animal Reproduction INIA Madrid 28040 Spain

In this study, we evaluated the effects of genistein supplementation of the thawing extender on frozen-thawed human semen parameters. We analyzed the effect of supplementation on sperm motility, capacitation （membrane lipid disorder）, reactive oxygen species （ROS） generation, chromatin condensation and DNA damage. Using this preliminary information, it maybe possible to improve the cryopreservation process and reduce the cellular damage. We have confirmed that the isoflavone genistein （10 μmol L-1） has antioxidant properties on the frozen-thawed spermatozoa. This results in a decreased ROS production that shows a slight improvement in the sperm motility, and decreases the membrane lipid disorder and DNA damage caused by cryopreservation. These results suggest an effect of genistein on sperm functionality that could be of interest for assisted reproduction treatments using frozen- thawed human spermatozoa, but further studies will be necessary to confirm our findings and to evaluate the possible clinical applications.

A novel porous and crystalline two-dimensional(2D)electrochemically active covalent organic framework(COF)based on ortho-quinone units has been prepared as an innovative approach towards the development of organic cathode materials with multiple redox sites as an efficient electrocatalyst for the oxygen reduction reaction(ORR).In contrast with most of the previously reported COFs as electrocatalysts for the ORR,the electrocatalytic application of this material towards ORR has been investigated without adding any metal or conductive supporting material and avoiding any additional carbonization ***,the electrochemical properties of the COF material have been compared with two analogue amorphous frameworks with similar chemical composition,which points out the important role of the enhanced crystallinity and porosity of the COF network in its superior performance as an electrocatalyst towards ORR.

作者： Andrea Cacerez Maura Casales Dulce Maria Ortega-Toledo jose Gonzalo Gonzalez-Rodriguez lorenzo Martinez Departamento de Ingenieria Quimica Metalurgica Facultad de Quimiea U niversidad Nacional Autonoma de Mexico MexicoD.F. 04510 Mexico Universidad Nacional Autonoma de Mexico Instituto de Ciencias Fisicas Av.

This study is a contribution to the behavior of the corrosion process of steel by carbon dioxide (CO2) and the formation the FeCO3 (siderite) by using both weight loss and electrochemical techniques when the material is exposed to a CO2 saturated 3% NaCl solution at 50 °C. The study included the analysis of an imidazoline based inhibitor which was relevant in the process of mitigating the carbonate layer formation. The test was elapsed during 336 h in an electrochemical cell where several EIS studies were performed along the test to characterize the iron carbonate layer formation as well as the role of the corrosion inhibitor. Post test SEM and X Ray Diffraction studies on coupon materials revealed the iron carbonate layer characteristics, as well as the role of the inhibitor in the control of the layer formation.

Prognostic significance of heart rate in hospitalized patients presenting with myocardial infarction

World Journal of Cardiology 2012年第1期4卷 15-19页

作者： lorenzo Fácila Pedro Morillas Juan Quiles Federico Soria Alberto Cordero Pilar Mazón manuel Anguita Cándido Martín-Luengo jose Ramón Gonzalez-Juanatey Vicente Bertomeu Department of Cardiology Consorcio Hospitalario General de Valencia Department of Cardiology Hospital Universitario de San Juan Department of Cardiology Hospital Virgen de la Arrixaca Department of Cardiology Hospital Clínico Universitario Santiago de Compostela Department of Cardiology Hospital Reina Sofía Department of Cardiology Hospital Universitario de Salamanca

AIM: To investigate the prognostic significance of resting heart rate in patients with acute coronary syndrome (ACS), independent of other known factors. METHODS: Patients 40 years of age or older who had been admitted with acute coronary syndrome (ACS) to one of the 94 hospitals participating in the Prevalence of Peripheral Arterial Disease in Patients with Acute Coronary Syndrome (PAMISCA) study were included. Patients were divided into two groups based on their resting heart rate (HR ≥ or < 70 bpm). Complications were recording during a follow-up period of 1 year. RESULTS: There were 1054 ACS patients analyzed (43.5% with ST segment elevation and 56.5% without elevation). Mean age was 66.6 ± 11.7 years, 70.6% were male and 29.4% of subjects were female. During follow-up, more patients in the HR ≥ 70 bpm group were hospitalized for heart failure and they also had a higher mortality rate. In the multivariate analysis, a heart rate of ≥ 70 bpm was independently related to overall mortality during the follow-up period (hazard ratio 2.5; 95% confidence interval, 1.26-4.97, P = 0.009). CONCLUSION: A resting heart rate ≥ 70 bpm in patients who survive an ACS is an indicator of a high risk of suffering cardiovascular events during follow-up.
