Salmonella typhimurium responds chemotactically to gradients of divalent cations in the presence of citrate ions. The actual chemoeffector is the citrate-metal ion complex, which acts as an attractant. Citrate (which is also a chemoeffector for Salmonella) and the citrate-metal ion complex are reco...
The purpose of this study was to compare each of the 14 naturally occurring lanthanoid metal ions for ability to stimulate pro-fibrotic responses in human dermal fibroblasts. When fibroblasts were exposed to individual lanthanoids over the concentration range of 1–100μM, increased proliferation ...
The response of the node of Ranvier can be prolonged up to 5 to 6 seconds by addition to the medium of minute amounts of certain metal ions. This prolongation involves a change from a triangular to a rectangular configuration. The properties of the prolonged nerve-fiber responses are very si...
Issues relating to metal ion acquisition and ion homeostasis that may be essential for the survival of plants, pathogens and herbivores competing in the same environment were highlighted. Besides, the influence of heavy metals on insects, especially aphids and pathogenic fungi, was shown. Our ...
Metal ion release is associated with the cytotoxicity of manufactured nanoparticles;however, the role of metal ion release in allergy aggravation remains to be elucidated. Therefore, we examined the allergy aggravation potential of several soluble manufactured nanoparticles (ZnO, CuO, NiO, MgO, and ...
α-D-glucose and parameters of metal ion are as followsZ is pesitive charge of metal ion, r is radius of metal ion in catalysts, I is tovalent parameter,α is polarizability of metal ion, D is parameter which depends on the electron configuration of metal ion and the d electron number...
accounting for more than 2% of human genes34. Some members have also been linked to immunomodulation and inflammation35,36,37. Disruption of ZNF has been associated with metal-ion toxicity, a secondary effect of metal concentration changes, altering gene expression and DNA repair38. Importantly, ...
Together, these findings support the important regulatory functions of the complex formed by metformin-bound metal ions, such as copper and iron in vivo. Based on previous molecular docking data39, we used the structure simulation to construct the NGAL bound to the metformin–Fe complex via the ...
Thermal-runaway experiments on consumer Li-ion batteries with metal-oxide and olivin-type cathodes Li-ion batteries play an ever-increasing role in our daily life. Therefore, it is important to understand the potential risks involved with these devices. ... Andrey W.Golubkov,DavidFuchs,JulianWag...
