“Opening” The Mesenchymal Stem Cell Tool Box
Adult mesenchymal stem cells (MSCs) are adherent stromal cells able to self-renew and differentiate into a wide variety of cells and tissues. MSCs can be obtained from distinct tissue sources and have turned out to be successfully manipulated in vitro. As adult stem cells, MSCs are less tumorigenic than their embryonic correlatives and posses another unique characteristic which is their almost ...
متن کاملconstruction and validation of a computerized adaptive translation test (a receptive based study)
آزمون انطباقی رایانه ای (cat) روشی نوین برای سنجش سطح علمی دانش آموزان می باشد. در حقیقت آزمون های رایانه ای با سرعت بالایی به سمت و سوی جایگزین عملی برای آزمون های کاغذی می روند (کینگزبری، هاوسر، 1993). مقاله حاضر به دنبال آزمون انطباقی رایانه ای برای ترجمه می باشد. بدین منظور دو پرسشنامه مشتمل بر 55 تست ترجمه میان 102 آزمودنی و 10 مدرس زبان انگلیسی پخش گردید. پرسشنامه اول میان 102 دانشجوی س...
methGraph: a genome visualization tool for PCR-based methylation assays.
Abnormalities in DNA methylation of CpG islands that play a role in gene regulation affect gene expression and hence play a role in disease, including cancer. Bisulfite-based DNA methylation analysis methods such as methylation-specific PCR (MSP) and bisulfite sequencing (BiSeq) are most commonly used to study gene-specific DNA methylation. Assessing specificity and visualizing the position of ...
متن کاملRapid expansion of the spermatogonial stem cell tool box.
R ecently, great technological progress has been achieved in spermatogonial stem cell (SSC) research. In this issue of PNAS, Kanatsu-Shinohara et al. (1) describe yet another important novel use for SSCs. Based on a successful long-term culture protocol for mouse SSCs, this group has designed a way to produce knockout mice from SSCs with an efficiency that is at least comparable with that of em...
متن کامل1 A Tool Box for Compiler Construction
This paper presents a set of tools supporting the construction of nearly every compiler phase. Design goals of this tool box have been practical usability, significantly reduced effort for compiler construction, and high quality of the generated compilers. Especially efficiency should be competitive to hand crafting. Currently modules in the target languages C and Modula-2 can be generated. Fir...
