Plants are exposed to antibiotics produced by soil microorganisms, but little is known about their responses at the transcriptional level. Likewise, few endogenous mechanisms of antibiotic resistance have been reported. The Arabidopsis thaliana ATP Binding Cassette (ABC) transporter AtWBC19 (ABCG19) is known to confer kanamycin resistance, but the exact mechanism of resistance is not well under...

Background. MRI has emerged for the noninvasive assessment of iron overload in various tissues. The aim of this paper is to evaluate hepatic and pancreatic iron overload by T2(∗) weighted gradient echo MRI in young beta-thalassemia major patients and to correlate it with glucose disturbance and postsplenectomy status. Subjects and Methods. 50 thalassemic patients, in addition to 15 healthy cont...

Because of continuous blood transfusions, thalassemia patients are subjected to peroxidative tissue injury by the secondary iron overload. In accordance, analysis of serum from 42 P-thalassemia patients, aged 4 t o 40 years, showed that the mean concentrations of conjugated diene lipid hydroperoxides (CD), lipoperoxides evaluated as malondialdehyde/ thiobarbituric acid (MDA/TBA) adducts, and pr...

Purpose: Superparamagnetic iron oxide (SPIO) nanoparticles are efficient contrast agents for molecular and cellular MR imaging [1]. They are usually considered to be negative contrast agents, since their magnetic moment causes signal dephasing which results in signal voids on T2* weighted images. However SPIO agents also have intrinsic T1 shortening properties [2] that can induce signal enhance...

The existence of lactoferrin was first reported by S0rensen and S0rensen,' who observed a red protein fraction in human milk. The protein was first isolated by Groves2 from bovine and by Johansson3 from human milk, and subsequent studies showed that this protein (which has been variously called red milk protein, ekkrinosiderophilin, and lactotransferrin) is strikingly similar in many respects t...

Iron folic acid (IFA) supplementation is used world over for reducing the prevalence of anemia. The objective of the present investigation is to study the sustainable effect of long term weekly Iron Folic Acid supplementation along with deworming on growth and haemoglobin status of rural school children. Method: Three schools were selected for the study. One school was a control group where no ...

A new analytical protocol for the challenging analysis of total dissolved iron at the low picomolar level in oceanic waters suitable for onboard analysis is presented. The method is based on the revision of the adsorptive properties of the iron/2,3-dihydroxynaphthalene (Fe/DHN) complexes on the hanging mercury drop electrode with catalytic enhancement by bromate ions. Although it was based on a...
