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 ...

We investigated the antimicrobial activity of four polymyxin B components, B1, B2, B3, and isoleucine (Ile)-B1, individually and in combination. B3 was the most active agent against all organisms tested except Acinetobacter baumannii, for which Ile-B1 was most active. One combination met the criteria for synergy, B3 plus Ile-B1. No combinations exhibited antagonism. The dominant components of p...

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...

Bu çalışmada, alizarin red S’in silika jel üzerine çözeltiden adsorpsiyonu araştırılmıştır. pH, adsorbent konsantrasyonu ve temas süresi gibi etkenlerin S boyar maddesinin adsorpsiyon davranışı üzerindeki etkisi incelenmiştir. 25 0C sıcaklıkta, 20 mg adsorban mg/L adsorbat çözeltilerle kinetiği, yalancı birinci mertebeden ikinci modelleri olmak üzere iki kinetik model kullanılarak Adsorpsiyonun...
