Plant microRNAs (miRNAs) play pivotal roles in many biological processes. Although many miRNAs have been identified in various plant species, the functions of these miRNAs remain largely unknown due to the shortage of effective genetic tools to block their functional activity. Recently, miRNA target mimic (TM) technologies have been applied to perturb the activity of specific endogenous miRNA o...

یکی از روش¬های جدید وکارامد برای خاموش¬کردن اختصاصی ژن ها پس از نسخه ¬برداری استفاده از rna می باشد. تداخل ژنی، یک وسیله ی مهم دفاعی در زیست¬شناسی مولکولی و به خصوص در ارگانیسم های رده ی پایین است که در آن قطعات مشخصی از rna دو رشته¬ای، در بیان یک ژن خاص مداخله می کنند. تداخل rna اخیرا به عنوان یک روش آزمایشی موفق به منظور تعیین عملکرد ژن ها از طریق تخریب ژن ها به کار رفته است. این فناوری قادر ...

Unitary random matrix ensembles Z n,N (detM) α exp(−N TrV (M)) dM defined on positive definite matrices M , where α > −1 and V is real analytic, have a hard edge at 0. The equilibrium measure associated with V typically vanishes like a square root at soft edges of the spectrum. For the case that the equilibrium measure vanishes like a square root at 0, we determine the scaling limits of the eig...

A long-gap ac arc with a length of more than 10 m (secondary arc) is normally generated at the short-circuit channel after single-phase-to-ground fault. In previous studies, breakdowns secondary arcs have mainly been considered as electrical breakdowns, ignoring role heat in channel. Besides, extinction-reignition theory arc, i.e., dielectric strength recovery theory, still lacks support experi...

Murine dendritic cells (DCs) of the established JAWS II cell line were transduced with a retroviral vector carrying murine interleukin 12 (IL-12) genes (JAWS II/IL-12 cells). The JAWS II/IL-12 cells produced approximately 9-18 ng IL-12 protein/ml/5 x 10(5) cells/48 h and displayed an increased CD80 and CD86 expression as well as major histocompatibility complex antigen up-regulation. The JAWS I...

Nowadays, there are many metrics for overall Quality of Experience (QoE), both those with Full Reference (FR), such as Peak Signal-to-Noise Ratio (PSNR) or Structural Similarity (SSIM), and No (NR), Video Indicators (VQI), which successfully used in video processing systems to evaluate videos whose quality is degraded by different scenarios. However, they not suitable sequences recognition task...

RNA interference (RNAi) is a highly specific gene-silencing phenomenon triggered by dsRNA. This silencing mechanism uses two major classes of RNA regulators: microRNAs, which are produced from non-protein coding genes and short interfering RNAs (siRNAs). Plants use RNAi to control transposons and to exert tight control over developmental processes such as flower organ formation and leaf develop...

Midsystolic notching (MSN) on the pulsed-wave Doppler right ventricular (RV) outflow tract (RVOT) flow velocity profile is a unique finding in pulmonary hypertension (PH), reflecting enhanced and accelerated reflection waves from vascular tree. Although presence of MSN well-recognized marker disease severity prognosis noncardiac PH,1Takahama H. McCully R.B. Frantz R.P. Kane G.C. Unraveling RV e...

Single-unit recording and retrograde tracing techniques were used to assess the receptive field properties, topography, and projections of rat trigeminal primary afferent neurons subsequent to transection of the infraorbital (IO) nerve in adulthood. Four hundred and fifty-eight units were recorded in the trigeminal ganglion ipsilateral to nerve section. Of these, 66.6% had IO receptive fields. ...
