Novel phototherapeutic agents： Investigation and progress of hypocrellin derivatives

Hypocrellins, as a kind of novel phototherapeutic agents, have several advantages over the clinically used hematoporphyrin derivatives, including high-excited triplet state yield, high phototoxicity, low dark toxicity, and rapid metabolism. However, they exhibit little absorption in the photodynamic window (600--900 nm) and are not water soluble, which limits their application in photodynamic therapy. Sulfonated and metal-ioned hypocrellins have been designed and synthesized to improve their water solubility.Unfortunately, the water-soluble derivatives obtained exhibit lower photodynamic activity than the parent hypocrellins.Thiolated and aminated hypocrellins have also been designed and synthesized to enlarge their photoresponse. Among them,the aminated hypocrellins possess the highest photodynamic activity. We recently have further designed and synthesized some amphiphilic aminated hypocrellin derivatives. Thus,not only the photoresponse but also the water solubility is enhanced. The experiments in vitro and in vivo on the derivatives are under way at present.     

谁偷偷窃走了我们的营养

哈根达斯PK本和杰瑞

炎炎夏日里最爽口的食物是冰激凌,而各种冰激凌中,哈根达斯大概是唯一畅销中美、东西闻名的品牌。不过同是哈根达斯,在中美两国消费者心中却有着截然不同的形象。在中国,哈根达斯等同于高品位、高价位、高消费。而在美国,哈根达斯也是名副其实的“三高”——高糖、     

怎样吃更健康

吃东西,如何能摄入更多营养？首先要明白一个道理,并不是吃10种食物就一定比吃5种食物摄入的营养更多更好。只要吃对了方法,有可能5比10大。     

吃软食不一定有益健康

常言道吃软不吃硬,珠不知食物越坚硬,对人体越有好处。英国科学家做了一项研究,让两组四周大的白老鼠吃一模一样的食物。唯一不同的是,一组食物是硬的,另外一组则打进空气让食物变得松软,但实际重量与热量维持不变。结果白老鼠36周大的时候,吃软食的白老鼠比吃硬食的那组胖了30％。     

早上喝奶 加勺蜂蜜

早上空腹喝杯蜂蜜水能润肠通便,早餐一杯牛奶则能强壮骨骼。但很少有人会想到把它们配在一起吃。其实,早餐奶里加勺蜂蜜,能让这两种食物达到最佳的营养互补,起到1＋1〉2的作用。     

Potential influence of water level changes on energy flows in a lake food web

Large seasonal water-level fluctuations may influence isotopic signatures of primary producers and the types and amounts of these potential food sources accessible to aquatic fauna of Poyang Lake,the largest freshwater lake in China.In this study,the isotopic signatures of primary producers and consumers were determined,stable carbon and nitrogen isotope analysis and mixing models were combined to investigate the influence of water levels on the diet and isotopic composition of Poyang Lake fish and inverteb...
