A polyoma-based episomal vector efficiently expresses exogenous genes in mouse embryonic stem cells.
We describe the ability of novel episomally maintained vectors to efficiently promote gene expression in embryonic stem (ES) cells as well as in established mouse cell lines. Extrachromosomal maintenance of our vectors is based on the presence of polyoma virus DNA sequences, including the origin of replication harboring a mutant enhancer (PyF101), and a modified version of the polyoma early reg...
To develop a practical immunohistochemistry panel for distinguishing lymphoblastic lymphoma from Ewing sarcoma (ES), we evaluated 17 ES and 27 lymphoblastic lymphoma and leukemia cases with antibodies to CD99, terminal deoxynucleotidyl transferase (TdT), leukocyte common antigen (LCA), CD43, CD79a, CD20, CD3, vimentin, and neuron-specific enolase (NSE). Three cases were bone lymphomas, 2 initia...
Rare human immunodeficiency virus 1-infected individuals, termed elite suppressors (ES), maintain plasma virus levels of <50 copies/ml and normal CD4 counts without therapy. The major histocompatibility complex class I allele group human histocompatibility leukocyte antigen (HLA)-B*57 is overrepresented in this population. Mutations in HLA-B*57-restricted epitopes have been observed in ES, but ...
"The child is father of the man" is the philosophy of the paediatrician, hence the recent trend of intense interest in child development, which embraces the study of factors which influence the growth of the body, mind, personality and spirit from conception to maturity and ultimate achievement. As practitioners of medicine it is natural that much of our effort should be used in the diagnosis a...
مقدمه و اهداف مطالعه حاضر به منظور بررسی تکرارپذیری درون آزمونگر نرمافزار همزمانسازی(Synchronization) در بررسی همزمان عضله تیبیالیس انتریور از نظر پارامترهای سونوگرافی و دینامومتری در حین انقباض در افراد سالم غیرورزشکار انجام شد. این نرمافزار به منظور افزایش توانایی در ثبت همزمان تصاویر اولتراسونوگرافی و دادههای دینامومتر استفاده شد. مواد و روشها در مطالعه حاضر تکرارپذیری پارامترهای ساختار...
the identification of a large number of antigens with potential for development of new tuberculosis vaccine has been accomplished in recent years. this study was designed for cloning and expression of esat-6 as a potent antigen of mycobacterium tuberculosis. selected gene (rv3875) was amplified by pcr and product was ligated into expressing plasmid vector pqe30 and recombinant pqe30-es plasmid ...
The objective of this study is to investigate the determinants of mean trip distance traveled by different mode types. The study uses data from the Hamilton CMA in Canada, and multilevel models to investigate demographic aging factors, gender differentials, and neighbourhood attributes on distance traveled. The results of the study validate previous findings regarding the decline in distance tr...
BACKGROUND Mouse embryonic stem (ES) cells can differentiate into female and male germ cells in vitro. Primate ES cells can also differentiate into immature germ cells in vitro. However, little is known about the differentiation markers and culture conditions for in vitro germ cell differentiation from ES cells in primates. Monkey ES cells are thus considered to be a useful model to study prima...
فرضیه: پساب صنایع کاغذسازی با توجه به دارابودن ترکیبات پلیمری نظیر لیگنین، برای محیط زیست و سلامت عمومی مضر است. در این پژوهش، از غشاهای فرافیلترکردن (UF) و الکتروریسیشده (ES) پلیآکریلونیتریل (PAN) برای جداسازی لیگنین پساب کارخانه کاغذسازی استفاده شد. روشها: برای بهبود فرایند فرافیلترکردن و بهینهسازی عوامل مؤثر بر آن شامل غلظت پساب، فشار و غلظت PVP در برابر شار و پسزنی، روش سطح پاسخ بهک...
Background This research studies the effects of activation and inhibition of Wnt3A signaling pathway in buffalo (Bubalus bubalis) embryonic stem (ES) cell-like cells. MaterialsAndMethods To carry on this experimental study, the effects of activation and inhibition of Wnt3A signaling in buffalo ES cell-like cells were examined using Bio (0.5 mM) combined with WNT3A (200 ng/ml), as an activator, ...
