Introduction Roughly 30 peer reviewed papers have been published on B1+ mapping in the last 2 years from 2010 to 2011. This shows the vitality of a research area that has started back in the 80’s [1, 2]. The RF field behavior in biological tissue and its spatial variations was assessed very early [3]. The transmit RF field can be described by a time independent, spatially varying B1+ map times ...

where the sum is over all different solutions in nonnegative integers b1, . . . , bm of b1 + 2b2 + · · · + mbm = m, and k := b1 + · · · + bm. For example, when m = 3 this instructs us to look at all solutions in nonnegative integers of the equation b1 + 2b2 + 3b3 = 3. We can have b3 = 1, b1 = 0 = b2, in which case k = 1 and we get the term 3! 0! 0! 1! ′ ( f (t)) ( f ′′′(t) 3! ) = g′ ( f (t)) f ...

Approximately 200 samples of rice (including white, brown, red, black, basmati and jasmine, as well as wild rice) from several different countries, including the United States, Canada, Pakistan, India and Thailand, were analysed for aflatoxins, ochratoxin A (OTA) and fumonisins by separate liquid chromatographic methods in two different years. The mean concentrations for aflatoxin B(1) (AFB(1))...

The aim of the study was to determine the mycobiota and natural levels of mycotoxins such as aflatoxin B1 (AFB1), ochratoxin A (OTA), fumonisin B1 (FB1), and deoxynivalenol (DON) present in brewers grains pre- and poststored intended for bovine intensive rearing. Poststored (80%) samples had counts higher than 1 × 10(4) colony-forming units (CFU/g). Cladosporium spp. and Aspergillus spp. were i...

Fumonisin B1 is associated with various animal and human carcinomas and toxicoses, including leukoencephalomalacia, hepatocarcinoma, pulmonary edema and esophageal carcinoma. We have examined the cellular effects of fumonisin B1 in vitro using cellular model systems relevant to potential human target tissues. Although fumonisin B1 has been described as a mitogen in Swiss 3T3 cells based on stim...

Chemotherapeutic drugs ideally should take advantage of the differences between transformed and normal cells and induce apoptosis only in cancer cells. One such difference may be the overexpression of cyclin B1 protein in cancer cells, which is required for the proper progression through mitosis. Previously, we showed that treatment of human prostate cancer cells with 2-methoxyestradiol (2-ME) ...

Background—b-Blockers are the first line of therapy for hypertension. However, they are associated with side effects because of central nervous system (CNS) effects and b2-adrenergic antagonism. To overcome these problems and provide a long-term b1-blockade, antisense oligonucleotides against rat b1-adrenergic receptor (b1-AR) mRNA (b1-AS-ODN) were designed and tested for the ability to inhibit...
