Iron toxicity

Ebook "Water treatment technologies for the removal of high-toxicity pollutants" process requires interdisciplinary approach; it is critically important to stimulate interactions between medical doctors, chemists, physicist, materials scientists, engineers and policy makers, which are already experienced in their specific areas. It is also our ethical obligation to preserve existing water resources and existing eco systems enhancing their biodiversity.

Ebook "Copper and bacteria: Evolution, homeostasis and toxicity" summarizes the current knowledge of copper toxicity, homeostasis and resistance in bacteria, in which proteins like copper ATPases, copper chaperones and copper-responsive regulators of gene expression play major roles. The author also discusses the metallation of cuproenzymes. The evolution of the use of copper by cells and of copper-homeostatic proteins are is also considered in this brief.

The impact of Fe2+ (iron)toxicity on genomic instability, DNA methylation status, and Long Terminal Repeat Retrotransposons (LTR RTs) polymorphisms on Zea mays is unknown. We investigated the toxicity of Fe2+ using Random Amplified Polymorphic DNA (RAPD), Coupled Restriction Enzyme Digestion-Random Amplification (CRED-RA) and Inter Retrotransposon Amplified Polymorphism (IRAP) assays in Zea mays seedlings, respectively.

Iron oxide nanoparticles have been known to be non-toxic and are among the most widely used nanomaterials in life, from the medical, agricultural to environmental fields. However, so far, the understanding of the interaction of nanoparticles, in general, and iron oxide nanoparticles, in particular, with the environment and the flora and fauna ecosystems is still limited.

Ferrous iron (Fe) and zinc (Zn) at high concentration in the soil cause heavy metal toxicity and greatly affect rice yield and quality. To improve rice production, understanding the genetic and molecular resistance mechanisms to excess Fe and Zn in rice is essential. Genome-wide association study (GWAS) is an effective way to identify loci and favorable alleles governing Fe and Zn toxicty as well as dissect the genetic relationship between them in a genetically diverse population.

Metals including iron, copper and zinc are essential for physiological processes yet can be toxic at high concentrations. However the role of these metals in the progression of cancer is not well defined. Here we study the anti-tumor activity of the metal chelator, TPEN, and define its mechanism of action.

A field experiment was conducted during Kharif 2011 in iron toxic low land soil of Central research Station, OUAT, Bhubaneswar. The experiment was conducted in RBD with three replications on a typical iron toxic Aeric Haplaquept soil with recommended dose of fertilizers (N: P: K) by taking rice cultivar ‘Jajati’ as a test crop. Twelve treatment combinations, consist of four levels of K (0, 40, 80 and 120 kg ha-1) and three levels of zinc (0, 2.5 and 5 kgha-1) were imposed on concerned plots.

Iron toxicity and acidity are the major constraints in the laterite derived paddy soils of Kerala. More than 90 % of the midland lateritic rice soils in the northern part of Kerala are strongly acidic in reaction with pH values in the range of 4.5 to 5.5. The content of 0.1 N HCl extractable Fe in soil varied from 52.21 – 414.9 mg kg-1 and more than 50 % of the rice soils showed iron toxicity problem (> 250 mg kg-1 of available iron).

Iron oxide nanorods were synthesized by chemical co-precipitation method. The structural and morphological characteristics of the as-synthesized nanorods were analyzed by Xray diffraction (XRD) and scanning electron microscopy. The results show that the iron oxide nanorods include the mixture of Fe3O4, γ-Fe2O3 and FeOOH with the diameter and the length of iron oxide nanorods to be 30 and 100 nm, respectively. The iron oxide nanorods were then dispersed and deposited on the gold electrode of quartz crystal microbalance (QCM) for the gas sensor.

The diagnosis of places of varietal diversity of rice in Guinea was made from survey data from several farms in 41 villages themselves distributed in the 2 natural regions of Lower Guinea and Forest Guinea. The descriptors used are the number of known varieties and varieties cultivated at different scales, as well as their utilization rate. The latter makes it possible to classify the Sativa and Glaberrima varieties at the village level and to identify improved and local varieties of notoriety.

F2 population obtained from F1 cross between Tulasi (Most tolerant genotype) and CUL8709 (Most susceptible genotype). 300 F2 plants and their parents were screened at 800 ppm of Fe. Phenotyping screening of F2 plants under iron toxic levels indicated presence of wide variability for shoot length, root length, total number of roots, number of fresh roots, shoot weight, root weight and visual scoring for iron-toxicity symptoms. The measures of skewness and kurtosis for various traits revealed a large quantitative variability.

Nonspecific distribution and uncontrollable release of drugs in conventional drug delivery systems (CDDSs) have led to the development of smart nanocarrier-based drug delivery systems, which are also known as Smart Drug Delivery Systems (SDDSs). SDDSs can deliver drugs to the target sites with reduced dosage frequency and in a spatially controlled manner to mitigate the side effects experienced in CDDSs. Chemotherapy is widely used to treat cancer, which is the second leading cause of death worldwide.
