Current safety regulations for local radiofrequency (rf) heating, developed for externally positioned rf coils, may not be suitable for internal rf coils that are being increasingly used in interventional MRI. This work presents a two-step model for rf heating in an interventional MRI setting: (1) the spatial distribution of power in the sample from the rf pulse (Maxwell's equations); and (2) t...

The combination of cytoplasmic male sterility (CMS) in one parent and a restorer gene (Rf) to restore fertility in another are indispensable for the development of hybrid varieties. To genotype rice lines at the restoring fertility (Rf) loci, 38 lines were crossed with a sterile tester (rfrf) line. Pollen fertility test was performed to identify sterile and fertile F1 hybrids. Seven lines were ...

Root-knot nematodes, Meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. The most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. In the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. In the supplementary studie...

Background: DNA microarray is a useful technology that simultaneously assesses the expression of thousands of genes. It can be utilized for the detection of cancer types and cancer biomarkers. This study aimed to predict blood cancer using leukemia gene expression data and a robust ℓ2,p-norm sparsity-based gene selection method. Materials and Methods: In this descriptive study, the microarray ...

Five isoflavonoids, i.e. 5-hydroxy-7-methoxy-2’, 5’-dihydroxyisoflavone (AV4), 5, 7-dihydroxy-4’-methoxyisoflavone (AV6), 7-methoxy-5-hydroxy-4’-methoxy-2’-hydroxyisoflavone (AV7), 8-pregnyl genistein (AV9), 5,7-dihydroxy-8-pregnyl-4’-methoxy-2’-hydroxyisoflavone (AV10) and one coumarochromone – sophorophenolone (AV8) were isolated from EtOAc of in vitro callus cultures Astragalus vesicarius ss...

PURPOSE To improve the clinical utility of diffusion-weighted imaging (DWI) by extending the slice coverage of a high-resolution reduced field-of-view technique. THEORY Challenges in achieving high spatial resolution restrict the use of DWI in assessment of small structures such as the spinal cord. A reduced field-of-view method with 2D echo-planar radiofrequency (RF) excitation was recently ...

Misawa et al. (3) recently reported a PCR-based method for differentiating Campylobacter serotype O19 strains from nonO19 strains. In another study (2), the same investigators used restriction fragment length polymorphism analysis of flaA genes and random amplified polymorphic DNA analysis of C. jejuni strains to conclude that all serotype O19 strains are closely related, regardless of their ge...

Advancing health literacy (HL) research requires high-quality HL measures. This chapter provides an overview of the state of the science of HL measurement: where the field started, currently is, and should be going. It is divided into eight key sections looking at (1) the history of HL measurement, (2) the relationship between HL definitions and measurement, (3) the HL conceptual domains most a...
