A systematic review of antiglycation medicinal plants

Background and objectivesThe present review shows a list of anti-glycation plants with their anti-glycation activity mechanisms that can attract the attention of pharmacologist for further scientific research towards finding better remedy for diabetic complications.MaterialsGoogle scholar, Pubmed, Web of Science and Scopus were searched. The terms were advanced glycation end products (AGEs), medicinal plants, antiglycation products.Resultsplants that studied in this review inhibit glycation in several possible mechanisms. Some of these plants inhibit the production of shiff base and amadori products. The others inhibit the generation of amadori products in the advanced phase. Some others blocked the aggregation of AGEs and some plants have antioxidant activity and reduce AGEs formation by preventing oxidation of amadori product and metal-catalyzed glucoxidation.ConclusionThis review can help pharmacologist to find antiglycation natural substance that can be useful in treatment of diabetic complications.     

基于荧光定量PCR技术的当归不同炮制品中大肠埃希菌数量测定方法开发及比较研究

目的对当归不同炮制品中大肠埃希菌变化进行定量分析。方法建立荧光定量PCR方法,对当归不同炮制品、不同产地、不同收集企业、不同储藏时间的大肠埃希菌进行定量分析。结果不同炮制品中大肠埃希菌数量变化为生当归土炒当归酒当归;在不同产地的当归中以甘肃岷县地区所含的大肠埃希菌的数量最少;与零售企业相比,生产销售企业的当归和酒当归中大肠埃希菌的数量较少;不同储藏时间对当归和酒当归中大肠埃希菌数量有一定影响,随储藏时间的增加,大肠埃希菌的数量也在增加。对部分代表性样品进行平板计数法与荧光定量PCR法比较时发现,平板计数法结果多呈阴性,荧光定量PCR结果均呈阳性。结论所建立的荧光定量PCR法特异性、灵敏度、可靠性以及报告周期均优于平板计数法,可为当归不同炮制品中大肠埃希菌的快速、准确定量检测提供有效手段。     

Posición técnica sobre la leche y derivados lácteos en la salud y en la enfermedad del adulto de la Asociación Mexicana de Gastroenterología y la Asociación Mexicana de Gerontología y Geriatría

Milk is a liquid food that possesses an important quantity of highly bioavailable macronutrients. In addition, it is readily accessible, as well as relatively inexpensive. Given that the knowledge of physicians about nutrition and food composition is deficient, in general, many of the dietary interventions recommended in diverse clinical settings lack a scientific basis. The aim of the present review was to produce a technical opinion that serves as a frame of reference to best sustain recommendations for consuming milk and dairy products as daily nutrition in the adult and older adult. The effects of milk and dairy products during the pediatric stage are not addressed in the present work. The Asociación Mexicana de Gastroenterología and the Asociación Mexicana de Gerontología y Geriatría jointly discussed and analyzed topics dealing with the legal designation of milk, the classification and nutritional profile of cow's milk, its nutritional characteristics, its consumption in the adult, intolerance to cow's milk, and associations of milk consumption with digestive tract alterations and other conditions. Finally, certain aspects of milk consumption in the older adult and its relation to overall health are briefly discussed.     

Academic–Industrial Collaboration: Toward the Consilience of Two Solitudes

Current major advances in drug discovery can be traced back to pioneering contributions originating from academics over a century ago. Living in a symbiotic yet noninvasive coexistence, the academic community and the pharmaceutical industry have strived, each in their own way, to develop the modern medicines that benefit humankind today. The subject is presented from a historical and personal perspective.     

乳腺癌HSV—1,HSV—2与c—erbB—2关系的免疫组化研究

采用免疫组织化学Ｓ－Ｐ法检测５２例手术切除乳腺癌组织ｃ－ｅｒｂＢ－２蛋白和ＨＳＶ－１、ＨＳＶ－２表达情况。结果发现癌组织中ｃ－ｅｒｂＢ－２阳性３４例（６５．４％）；ＨＳＶ－１阳性３８例（７３．１％）；ＨＳＶ－２阳性１５例（２８．８％）。癌旁组织３２例，阳性分别为３例（９．４％）；１２例（３７．５％）；２例（６．３％）。乳腺癌中ｃ－ｅｒｂＢ－２阳性率明显高于癌旁组织。乳腺癌及癌旁的ＨＳＶ－１阳性率明     

Bleeding complications precipitated by unrecognized Gingko biloba use after liver transplantation

Because of its neurocognitive enhancing effects, Gingko biloba has emerged as amongst the most commonly used herbal products. We report a liver transplant recipient with potentially life-threatening toxicity resulting from Gingko biloba use. Seven days after a second liver transplantation for recurrent hepatitisB virus infection, subphrenic hematoma was documented in a 59-year-old Korean patient. Failure to control bleeding with CT-guided drainage necessitated exploratory laparotomy for the evacuation of a large subphrenic hematoma. Three weeks later, an episode of vitreous hemorrhage was documented. Unbeknownst to his care providers, the patient had been consuming Gingko biloba throughout the postoperative period. No further bleeding episodes occurred after the cessation of Gingko biloba use. Unrecognized use of herbal products may be associated with serious side effects and adverse clinical sequelae in transplant recipients. Given their increasing popularity, the use of herbal products should be routinely sought as part of the history in transplant recipients.     

从自由基生物学角度评价鸡肉质量的实验研究

本文把外观健康和非健康的活鸡各20只分成两组,宰后测其肝、腿肌中超氧化物歧化酶(SOD)含量和脂质过氧化产物丙二醛(MDA)水平,发现两组中上述指标值差异显著(P<0.050 ;同时对两组实验鸡胴体在宰后4小时做了感官鉴别,也判断出其品质存在差异。提示体内SOD活性和MDA水平可以反映鸡肉质量,比感官鉴别更具敏感性,同时也可以反映宰前鸡的健康状况。
