Evolutionary developmental biology is based on the principle that evolution arises from hereditable changes in development. Most of this new work has centred on changes in the regulatory components of the genome. However, recent studies (many of them documented in this volume) have shown that development also includes interactions between the organism and its environment. One area of interest c...
Grade II gliomas are slowly growing primary brain tumors that affect mostly young patients. Cytotoxic therapies (radiotherapy and/or chemotherapy) are used initially only for patients having a bad prognosis. These therapies are planned following the "maximum dose in minimum time" principle, i. e. the same schedule used for high-grade brain tumors in spite of their very different behavior. These...
Cogeneration power plants simultaneously generate power and usable heat in a single, integrated system, which achieves a degree of overall efficiency that is much greater compared to electricity production alone. This makes better use of energy conversion and reduces greenhouse gas emissions. Combined heat and power production is already relatively common in Europe while it is less common, for ...
انتقال dna به داخل یاخته های پستانداران بوسیله دندروزومها، یکی از جدیدترین روشهای انتقال dna به داخل یاخته محسوب می شود که مزایای زیادی نسبت به روشهای قدیمی تر مانند فسفات کلسیم، دکستران، لیپوزومها، دندریمرها و الکتروپوریشن دارند. دندروزومها، ارزان، خنثی و غیر سمی هستند. یاخته های اندوتلیال رگ بندناف انسان، نقش مهمی در خونسازی، عملکرد رگها و ایمنی زایی دارند با توجه به این اعمال فیزیولو...

in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
