We generated defined alterations in poliovirus protein-processing substrates and assayed the effects of these alterations with an in vitro expression system. A complete cDNA copy of the poliovirus genome was inserted into a bacteriophage T7 transcription vector. Using this expression template, we produced RNA transcripts containing defined regions of the poliovirus capsid precursor polypeptide ...
Porcine circovirus-like virus P1 is an important pathogen of the current pig industry, the infection mechanism is not entirely clear. Wnt signaling pathway plays an important role in the growth of young animals and infection of some viruses. This study was designed to demonstrate the effects of P1 infection on the Wnt signaling pathway. In vivo experiments, we demonstrated the down-regulatory e...
عضله رحم rat از نظر ساب تایپ های رسپتور p1 پورینرژیک مورد بررسی قرارگرفت . به این جهت آدنوزین و آنالوگهای آن مورد بررسی قرار گرفتند . نتایج بدست آمده نشان میدهند که آثار مهاری آدنوزین و آنالوگهایش بر روی دامنه انقباضات الکتریکی رحم rat بواسطه هیچیک از ساب تایپ های a1 و a2 صورت نمیگیرد، بلکه اینکار از طریق ساب تایپ جدیدی از رسپتور p1 انجام میگیرد. ترکیباتی که درموقعیت 5 حلقه ریبوزاستخلاف دارند (...
In this paper x, a are real numbers. Next we state a number of propositions: (1) If a 0 and (x − a) · (x + a) 0, then −a x or x a. (2) If a ¬ 0 and x < a, then x > a. (3) For every point p of E2 T such that |p| ¬ 1 holds −1 ¬ p1 and p1 ¬ 1 and −1 ¬ p2 and p2 ¬ 1. (4) For every point p of E2 T such that |p| ¬ 1 and p1 6= 0 and p2 6= 0 holds −1 < p1 and p1 < 1 and −1 < p2 and p2 < 1. (5) ...
Pericarp Color1 (P1) encodes an R2R3-MYB transcription factor responsible for the accumulation of insecticidal flavones in maize (Zea mays) silks and red phlobaphene pigments in pericarps and other floral tissues, which makes P1 an important visual marker. Using genome-wide expression analyses (RNA sequencing) in pericarps and silks of plants with contrasting P1 alleles combined with chromatin ...
Phase noise of the period-one (P1) nonlinear dynamical oscillation in an optically injected semiconductor laser is numerically investigated. The P1 dynamics causes the laser output intensity to oscillate at a widely tunable frequency for photonic microwave generation, although the intrinsic spontaneous emission in the laser inevitably degrades the microwave signal and manifests as the oscillati...
Natural killer (NK) cells exhibit cytotoxicity against variety of tumor cells and virus-infected cells without prior sensitization and represent unique lymphocytes involved in primary host defense. NKR-P1 is thought to be one of NK receptors mediating activation signals because cross-linking of NKR-P1 activates NK cells to exhibit cytotoxicity and IFN-gamma production. However, molecular mechan...
