خودناسازگاری در بادام توسط یک مکان ژنی با چندین آلل کنترل می شود. در این آزمایش بررسی تنوع آلل های احتمالی ناسازگاری با استفاده از واکنش زنجیره پلی مراز در 96 نمونه از گونه های مختلف بادام و گونه های خویشاوند آن انجام شد. واکنش زنجیره پلیمراز با استفاده از سه جفت آغازگر دژنره (PaConsI-F/EM-PC1consR، PaConsI-F/EM-PC3consR، EM-PC2consF/EM-PC3consR)، یک جفت آغازگر اختصاصی ناسازگاری (AmyC5R/ AS1II)...
The Epstein-Barr virus (EBV)-encoded viral protein kinase, EBV-PK (the BGLF4 gene product), is required for efficient nuclear viral egress in 293 cells. However, since EBV-PK phosphorylates a number of different viral and cellular proteins (including lamin A/C), the relative importance of each target during lytic viral replication remains unclear. We show here that an EBV PK mutant (PKmut; cont...
In order to overproduce bioinsecticides production by a sporeless Bacillus thuringiensis strain, an optimal composition of a cheap medium was defined using a response surface methodology. In a first step, a Plackett-Burman design used to evaluate the effects of eight medium components on delta-endotoxin production showed that starch, soya bean and sodium chloride exhibited significant effects o...
This paper presents research on a low power CMOS UWB LNA based on a cascoded common source and current-reused topology. A systematic approach for the design procedure from narrow band to UWB is developed and discussed in detail. The power reduction can be achieved by using body biased technique and current-reused topology. The optimum width of the major transistor device M1 is determined by the...
Architecture of higher plant chloroplast ribosomes involves additional protein domains over that found in the Escherichia coli ribosome, although the rRNAs in these two kinds of ribosomes are very similar in length and sequence (Subramanian, A. R. (1993) Trends Biochem. Sci. 18, 177-180). Here, we show that two chloroplast-specific protein domains (a novel chloroplast ribosomal protein of the 3...
The NOAH/DIAMOD program suite was used to automatically assign an experimental 2D NOESY spectrum of the 46 residue protein crambin(S22/I25), using feedback filtering and self-correcting distance geometry (SECODG). Automatically picked NOESY cross peaks were combined with 157 manually assigned peaks to start NOAH/DIAMOD calculations. At each cycle, DIAMOD was used to calculate an ensemble of 40 ...
1. Reinshagen M, Schutz E, Armstrong VW, Behrens C, von Tirpitz C, Stallmach A, et al. 6-thioguanine nucleotide-adapted azathioprine therapy does not lead to higher remission rates than standard therapy in chronic active Crohn disease: results from a randomized, controlled, open trial. Clin Chem 2007;53:1306–14. 2. Shipkova M, Armstrong VW, Wieland E, Oellerich M. Differences in nucleotide hydr...
The design of a 3.0-7.5 GHz UWB CMOS power amplifier (PA) for group 1~3 MB-OFDM UWB applications in TSMC 0.18-μm CMOS technology is presented. The UWB PA proposed in this paper uses a current-reused technique to enhance the gain at the upper end of the desired band, and the resistive feedback at the second stage is used to obtain gain flatness. The shunt-shunt feedback is used to enhance bandwi...
Thrombin-treated tumor cells induce a metastatic phenotype in experimental pulmonary murine metastasis. Thrombin binds to a unique protease-activated receptor (PAR-1) that requires N-terminal proteolytic cleavage for activation by its tethered end. A 14-mer thrombin receptor activation peptide (TRAP) of the tethered end induces the same cellular changes as thrombin. Four murine tumor cells (Lew...
