از مهمترین فواید تولید پروتئین های نوترکیب در گیاهان می توان به اقتصادی بودن آن نسبت به سیستم های صنعتی، تولید فرآورده های بیولوژیکی فعال و مشابه شکل طبیعی، تولید بالای پروتئین نوترکیب و غیره اشاره کرد. از طرف دیگر پایین بودن سطح بیان ترنسژن ها و همچنین خاموشی آن ها در نسل های بعد از مهمترین فاکتورهای محدودکننده در این زمینه می باشد. انتخاب بافت مناسب گیاه جهت بیان و نیز بهبود قطعه ژنی از جمله ...
To understand the genetic basis of pathways involved in the control of breathing, a large scale, high-throughput study using chromosomal substitution strains of rats is underway. Eight new consomic rat stains (SS-2(BN), SS-4(BN), SS-6(BN), SS-7(BN), SS-8(BN), SS-11(BN), SS-12(BN), SS-14(BN), SS-Y(BN)), containing one homozygous BN/NHsdMcwi (BN) chromosome on a background of SS/JrHsdMcwi (SS), w...
We previously showed that the authentic 5' splice site (5'ss) of the first exon in the human beta-globin gene is intrinsically stronger than a cryptic 5'ss located 16 nucleotides upstream. Here we examined by mutational analysis the contribution of individual 5'ss nucleotides to discrimination between these two 5'ss. Based on the in vitro splicing efficiencies of a panel of 26 wild-type and mut...
BACKGROUND School participation in collecting and reporting syndromic surveillance (SS) data to public health officials and school nurses' attitudes regarding SS have not been assessed. METHODS An online survey was sent to Missouri Association of School Nurses members during the 2013/2014 school year to assess whether K-12 schools were collecting and reporting SS data. Z-scores were used to a...
In real environments, the recorded speech signal is much affected by unwanted noise. Therefore, it is necessary to reduce the unwanted noise from the recorded noisy signal. The spectral subtraction (SS) and the flooring processing-improved SS (F-SS) have been proposed to achieve that. The F-SS iteratively estimates the clean speech signal by utilizing the SS. However, the F-SS generates the dis...
Silk sericin (SS) can accelerate cell proliferation and attachment; however, SS can be extracted by various methods, which result in SS exhibiting different physical and biological properties. We found that SS produced from various extraction methods has different molecular weights, zeta potential, particle size and amino acid content. The MTT assay indicated that SS from all extraction methods...
AIM The aim of this study was to evaluate whether coronary artery disease (CAD) severity exerts a gradient of risk in patients with aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS A total of 445 patients with severe AS undergoing TAVI were included into a prospective registry between 2007 and 2012. The preoperative SYNTAX score (SS) was dete...
The effects of Korean solar salt on an azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced colon cancer C57BL/6 mouse model were studied. Korean solar salt samples (SS-S, solar salt from S salt field; SS-Yb, solar salt from Yb salt field), nine-time-baked bamboo salt (BS-9x, made from SS-Yb), purified salt (PS), and SS-G (solar salt from Guérande, France) were orally administered at a conce...
Activated neutrophils increase erythrocyte phosphatidylserine (PS) exposure. PS-exposed sickle red blood cells (SSRBCs) are more adhesive to vascular endothelium than non-PS-exposed cells. An increase in SSRBC fetal hemoglobin (HbF) concentration has been associated with improved rheology and decreased numbers of vasoocclusive episodes. This study examined the effects of HbF, PS-exposed SSRBCs,...
