However, there was significantly higher differential accumulation of the transcripts in flag leaf as compared to seedling. In CRP 1660, transcripts pertaining to phytosiderophore biosynthesis like DMAS1-B, NRAMP2 and NAAT2-D showed greater accumulation. Additionally, corresponding miRNAs were also identified for these 28 transcripts. The findings will help in better understanding of molecular basis of Fe/Zn transport and accumulation in grain and subsequent utilization in breeding to improve Fe/Zn content in wheat grain. Three new acylphloroglucinol glucosides, rhodosides A-C (1-3), and three known ones (4-6) were isolated from the roots of Lysidice rhodostegia. The new structures were identified by MS, NMR, and acid hydrolysis. In addition, the antioxidant capacities of the isolated compounds were evaluated using DPPH radical-scavenging assay, and compounds 1-6 exhibited obvious antioxidant activities with IC50 values of 24.65 ± 1.27 to 38.11 ± 1.35 μM. BACKGROUND Vanadium (V) is an element with a wide range of effects on the mammalian organism. The ability of this metal to form organometallic compounds has contributed to the increase in the number of studies on the multidirectional biological activity of its various organic complexes in view of their application in medicine. OBJECTIVE This review aims at summarizing the current state of knowledge of the pharmacological potential of V and the mechanisms underlying its anti-viral, anti-bacterial, anti-parasitic, anti-fungal, anti-cancer, anti-diabetic, anti-hypercholesterolemic, cardioprotective, and neuroprotective activity as well as the mechanisms of appetite regulation related to the possibility of using this element in the treatment of obesity. The toxicological potential of V and the mechanisms of its toxic action, which have not been sufficiently recognized yet, as well as key information about the essentiality of this metal, its physiological role, and metabolism with certain aspects on the timeline is collected as well. The report also aims to review the use of V in the implantology and industrial sectors emphasizing the human health hazard as well as collect data on the directions of further research on V and its interactions with Mg along with their character. RESULTS AND CONCLUSIONS Multidirectional studies on V have shown that further analyses are still required for this element to be used as a metallodrug in the fight against certain life-threatening diseases. Studies on interactions of V with Mg, which showed that both elements are able to modulate the response in an interactive manner are needed as well, as the results of such investigations may help not only in recognizing new markers of V toxicity and clarify the underlying interactive mechanism between them, thus improving the medical application of the metals against modern-age diseases, but also they may help in development of principles of effective protection of humans against environmental/occupational V exposure. BACKGROUND Chromium (Cr) exists in the environment in two chemical forms; CrIII is an essential micronutrient for glucose and lipid metabolism, whereas CrVI is toxic and a recognised carcinogen through inhalation. Numerous studies have attempted to evaluate their transfer mechanisms from soil and solution media into plants, usually with respect to the hyperaccumulation, detoxification and tolerance of the plant to CrVI. METHODS Isotopically enriched species of Cr, added as 50CrIII and 53CrVI, were used to investigate transfer from solution into the root systems of Spinacia oleracea. In addition the effect of sulphate (SO42-), as a competitor for CrVI uptake, was investigated. Separation of 50CrIII and 53CrVI was undertaken using HPLC-ICP-QQQ following isolation of root solutions using freeze/thaw centrifugation. RESULTS Irrespective of supplied CrVI concentration (250, 500 or 1000 μg L-1), the dominant species in both apoplastic (routed through cell wall and intercellular space as a passive mechanism) and symts.

In this work, the modified poly(vinylidene fluoride) membrane (PVDF) with chemical stability and high mechanical strength was developed for laccase immobilization via covalent bonding. The key design for the synthesis of biocatalytic membrane is the construction of hybrid bio-inorganic structure on the surface of polydopamine (PDA)-coated PVDF (PDA@PVDF). In this respect, the PDA layer was used as a secondary platform for the grafting of 3-triethoxysilylpropylamine (APTES) modified Fe2O3@SiO2 cubes (FS@cubes) via a solvothermal process, resulting in the formation of FS@cubes-PDA@PVDF membrane. Subsequently, laccase was immobilized on the surface of FS@ cubes-PDA@PVDF via gluteraldehyde (GA) crosslinking (Lac-FS@ cubes-PDA@PVDF). The removal efficiency of congo red by Lac-FS@cubes-PDA @PVDF reached 97.1 % under optimal reaction conditions (pH 7.0 and temperature 35 ℃), which was more efficient than free laccase. Moreover, the as-prepared Lac-FS@cubes-PDA@PVDF not only exhibited an excellent stability after low temperature storage, but also showed an outstanding reusability. Therefore, we believe that this work opens up a potential strategy for removal of other water pollutants, and provide a simple and convenient way for large-scale applications of enzyme-catalysis. Flumequine was nano-immobilized by self-assembly on iron oxide nanoparticles, called surface active maghemite nanoparticles (SAMNs). CM 4620 solubility dmso The binding process was studied and the resulting core-shell nanocarrier (SAMN@FLU) was structurally characterized evidencing a firmly immobilized organic canopy on which the fluorine atom of the antibiotic was exposed to the solvent. The antibiotic efficacy of the SAMN@FLU nanocarrier was tested on a fish pathogenic bacterium (Aeromonas veronii), a flumequine sensitive strain, in comparison to soluble flumequine and the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) were assessed. Noteworthy, the MIC and MBC of soluble and nanoparticle bound drug were superimposable. Moreover, the interactions between SAMN@FLU nanocarrrier and microorganism were studied by transmission electron microscopy evidencing the ability of the complex to disrupt the bacterial wall. Finally, a preliminary in vivo test was provided using Daphnia magna as animal model.
