The condensation of nucleic acids into well-defined particles is an integral part of several approaches to artificial cellular delivery. Improvements in the efficiency of nucleic acid delivery in vivo are important for the development of DNA- and RNA-based therapeutics. Presently, most efforts to improve the condensation and delivery of nucleic acids have focused on the synthesis of novel conde...
ژن درمانی در سال های اخیر به عنوان یک ابزار توجه زیادی را در علم پزشکی به خود جلب کرده است. امروزه دو گروه از وکتورهای رایج در ژن درمانی وجود دارند: وکتورهای ویروسی و وکتورهای غیر ویروسی. وکتورهای ویروسی کارایی بالایی در انتقال ژن دارند اما به دلیل تحریکات سیستم ایمنی و سمیت، نقش آنها در انتقال ژن محدود شده است. سیستم های انتقال ژن غیر ویروسی، یکی از جایگزین های سیستم های ویروسی هستند که به ویژ...
RNA interference (RNAi) was first literaturally reported in 1998 and has become rapidly a promising tool for therapeutic applications in gene therapy. In a typical RNAi process, small interfering RNAs (siRNA) are used to specifically downregulate the expression of the targeted gene, known as the term "gene silencing." One key point for successful gene silencing is to employ a safe and efficient...
delivery of exogenous materials such as nucleic acids, peptides, proteins, and drugs into cells is an important strategy in modern cellular and molecular biology. recently, the development of gene carriers for efficient gene transfer into cells has attracted a great attention. furthermore, lack of effective drug delivery is one of the major problems of cancer chemotherapy. many physical methods...
objective: this study focused on the factors affecting the institutional delivery and delivery assisted by health professionals in urban slums. materials and methods: a semi-structured questionnaire was developed to collect information from women aged 15-49 who had at least one birth. totally 540 eligible women were interviewed. results: the results showed that around 20% of women delivered at ...
