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.     

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.     

CAD基因原核表达载体的构建及表达产物的活性鉴定

目的构建pCool—GST—ICAD／CAD的表达载体，并存大肠杆菌BL21（DE3）中表达具有生物学活性的CAD核酸酶？方法用PCR扩增CAD基因，将扩增产物克隆入pCool—GST—ICAD载体中构建出pCool—GST—ICAD／CAD表达载体。经酶切和电泳鉴定正确后，在大肠杆菌BL21（DE3）中诱导表达，表达产物经亲和层析、离子交换层析及凝胶过滤等方法分离纯化。最后用SDS—PAGE和DNA降解实验进行鉴定。结果构建了pCool—GST—ICAD／CAD原核表达载体，重组载体转化后表达出毫克级水平的GST—ICAD／CAD蛋白复合体。经分离纯化后得到纯度很好的CAD—ICAD篮白复合体，在SDS—PAGE电泳上旱现清晰的两条蛋白带。经DNA降解实验证明纯化所得的CAD蛋白具有非特异性降解DNA的核酸酶作用。结论成功制备了具有生物学活性的CAD核酸酶，为进一步研究细胞凋亡的作用机制提供了有效的制剂。     

重组人生长激素降解产物的检测分析

本文详细介绍了Ｓ－Ｂ电导率模型确定泥质砂岩储层含水饱和度的基本原理以及相应参数的确定方法。用该方法处理了大庆地区的树１３１井、萨南５丁４－检１３２井及杏９丁３检１３４井的一些层位，并将求得的含水饱和度与岩心分析的含水饱和度进行了对比，吻合得比较好。这说明了应用Ｓ－Ｂ模型确定储层的含水饱和度是可行的，结果比较好。
