Protein content is one of the main factors determining end-use quality wheat. NO APICAL MERISTEM-B1 (NAM-B1) a major gene regulating wheat grain protein content. The present study aimed to identify new genetic resources using wild-type NAM-B1 allele breed high-protein-content cultivars. We genotyped HIGH GRAIN PROTEIN CONTENT-B1 (GPC-B1) locus and in 165 A kompetitive allele-specific polymerase...
This paper describes a method for merging behavior specifications modeled by transition systems. Given two behavior specifications B1 and B2, Merge(B1, B2) defines a new behavior specification that extends B1 and B2. Moreover, provided that a necessary and sufficient condition holds, Merge(B1, B2) is a cyclic extension of B1 and B2. In other words, Merge(B1, B2) extends B1 and B2, and any cycli...
بیماری های عروق کرونر (cad) شایعترین عامل مرگ و میر ناشی از بیماری های قلبی- عروقی هستند و التهاب، عاملی پیشبرنده برای خطر ابتلا به این بیماری محسوب می گردد. فاکتور رونویسی nf?bتنظیم کننده کلیدی بسیاری از فرآیندهای سلولی و ژن های دخیل در تعدیل التهاب است و بسیاری از ژن های مرتبط با cad توسط nf?b تنظیم می گردد. حذف توالی attg ناحیه 94- پروموتر ژن nf?b1 منجر به کاهش سطح زیر واحد های این پروتئین (...
Kinins exert cardioprotective effects via 2 G-protein-coupled receptors, B1 and B2. Using B1 kinin receptor gene knockout mice (B1-/-), we tested the hypotheses that the B1 receptor plays an important role in preservation of cardiac function, whereas lack of B1 may accelerate cardiac remodeling and dysfunction after myocardial infarction, and that B2 receptors may compensate for lack of B1, whe...
Introduction B1 inhomogeneity in a human body increases as the strength of static magnetic field increases and the RF wavelength becomes smaller. Recently, various RF control methods have been developed to reduce B1 inhomogeneity. For example, some methods involve devices such as dielectric pads [1,2] or coupling coils [3,4], or techniques such as B1 shimming [5,6]. However, B1 inhomogeneity st...
Transmit SENSE. For this purpose, an ROI was drawn in the occipital lobe (white ROI Fig3) and two B1 Phase Shim solutions were calculated and applied in order to obtain an homogeneous B1 magnitude within this ROI: one based on the estimated B1 maps, another one based on the measured B1 maps. As can be seen in Fig3 (in degrees), both B1 Shim sets produced tremendous improvement in B1 efficiency ...
