Phytochemical overview and medicinal importance of Coffea species from the past until now

引用

Asian Pacific Journal of Tropical Medicine 2016年第12期9卷 1101-1110页

作者： éva Brigitta Patay Tímea Bencsik Nóra Papp Department of Pharmacognosy Faculty of PharmacyUniversity of Pécs

Coffea(coffee) species are grown in almost all countries along the Equator. Many members of the genus have a large production history and an important role both in the global market and researches. Seeds(Coffeae semen) are successfully used in food, cosmetic, and pharmaceutical industries due to its caffeine and high polyphenol content. Nowadays, the three best-known coffee species are Arabic(Coffea arabica L.), Robusta(Coffea robusta L. Linden), and Liberian coffees(Coffea liberica Hier.). Even though, many records are available on coffee in scientific literature, wild coffee species like Bengal coffee(Coffea benghalensis Roxb. Ex Schult.) could offer many new opportunities and challenges for phytochemical and medical studies. In this comprehensive summary, we focused on the ethnomedicinal, phytochemical, and medical significance of coffee species up to the present.

Room temperature deformation behavior of A1-8Fe-2Mo-2V-1Zr alloy produced by spray forming and subsequent warm-extrusion at 693 K and/or rolling at 423 K was investigated in terms of tensile test and microstructural *** the specimen processed by spray forming and warm extrusion, the microstructure consisting of equiaxed grains with the average grain size of 500 nm in the matrix phase and uniformly dispersed fine intermetallic A13(Fe, Mo, V, Zr) and A16(Fe, Mo, V, Zr) phases less than 100 nm was characterized. It was revealed that subsequent warm rolling after warm extrusion promotes precipitation of a fine dispersoid from the supersaturated matrix phase. Warm rolling was found to be effective to increase the yield and tensile strength in the high strain rate regime. Elongation of the warm rolled specimen showed highe r value than extruded specimen over the whole strain rate region studied.

Effects on the quality of frozen-thawed alpaca(Lama pacos)semen using two different cryoprotectants and extenders

引用

Asian Journal of Andrology 2005年第3期7卷 303-309,页

作者： AlexeiSantiani WilfredoHuanca RómuloSapana TeodosioHuanca NéstorSepúlveda raúlSánchez VeterinaryInstitute for Tropical and Highland Research Faculty of Veterinary MedicineUniversidad Nacional Mayor de San MarcosP.O.Box 03-5034Lima 41Perú OuimsachataExperimental Station National Institute of Agrarian ResearchPunoPerú Reproductive Biotechnology Center Universidad de La FronteraP.O.Box 54-DTemucoChile

Aim： To evaluate two extenders and two cryoprotectant agents （CPA） for alpaca semen cryopreservation. Methods： Semen samples were obtained from four adult alpacas （Lama pacos） and frozen using extender Ⅰ （TRIS, citrate, egg yolk and glucose） or extender Ⅱ （skim milk, egg yolk and fructose）, each containing either glycerol （G） or ethylene glycol （EG） as CPA. Consequently, four groups were formed： 1） extender Ⅰ-G; 2） extender Ⅰ-EG; 3） extender Ⅱ-G; and 4） extender Ⅱ-EG. Semen was diluted in a two-step process： for cooling to 5 ℃ （extenders without CPA）, and for freezing （extenders with CPA）. Viability and acrosome integrity were assessed using trypan blue and Giemsa stains. Results： When compared, the motility after thawing was higher （P 〈 0.05） in groups Ⅱ-EG （20.0 %±6.7 %） and Ⅱ-G （15.3 %±4.1%） than that in groups Ⅰ-G （4.0 %±1.1%） and Ⅰ-EG （1.0 %±1.4 %）. Viable spermatozoa with intact acrosomes in groups Ⅱ-EG （18.7 %±2.9 %） and Ⅱ-G （12.7 %±5.9 %） were higher than that in groups Ⅰ-G （5.7 %±1.5 %） and Ⅰ-EG （4.0 %±1.0 %）. Conclusion： The skim milk- and egg yolk-based extenders containing ethylene glycol or glycerol to freeze alpaca semen seems to promote the survival of more sperm cells with intact acrosomes than the other extenders. （Asian J Androl 2005 Sep; 7： 303-309）

Perspective on Local Governance Reform in China

引用

China & World Economy 2006年第2期14卷 16-31页

作者： Mingxing Liu Binwen Song ra Tao associate professor School of Government Peking University Beijing China. assistant professor Zhejiang University of Finance ＆ EconomicsChina. associate professor Center for Chinese Agricultural PolicyBeijing China

This paper is an attempt to present an analysis of China＇s decentralization and local governance practices, the dilemmas rooted in the current institution. We argue that the misbehavior of local government officials is endogenous to China＇s central-local structure and that competition among localities has become distorted and constrained by various policy burdens and development mandates imposed from above. The information asymmetry for the enforcement cost of mandates that exists between central and local governments not only leads to difficulties and distortions in local performance evaluations, but also creates opportunities for local bureaucracy expansion and rent-seeking. Enhancingfiscal transfers, or strengthening political restraint, although necessary, would be far from enough to solve the local governance problems. The ultimate solution entails an in-depth deregulation reform on factor mobility and a furthest eradication of policy mandates for the local government.
