Thymol is a famous plant-derived compound that has been widely used in pharmacy due to its antioxidant and antimicrobial properties. However, the modulation of intrinsic plant physiology by thymol remains unclear. It is a significant challenge to confer plant tolerance to Cd (cadmium) stress. In the present study physiological, histochemical, and biochemical methods were applied to investigate ...

Exposure of P. pdyrphczlum to a subthreshold challenge of Cd’+, which did not delay mitosis. elicited a protective response against a mitotic delay resulting from subsequent exposure to a suprathreshold challenge of Cd2+. Some characteristics of this protective response are herein identified. The concentration of Cd2+ in the subthreshold challenge could be lowered to lo-” M and maintain complet...

Three Ca(2+)-dependent procedures known to increase cation permeability of red blood cell membranes were tested with Cd2+ ions which equal Ca2+ ions both in their charge and the crystal radius, 1. Increase of non-selective permeability for monovalent cations by incubating the red cells in a Ca(2+)-free sucrose medium. Addition of Cd2+ to the suspension of leaky cells failed to restore the initi...

We previously reported that cell cultures of human proximal tubule (HPT) cells respond to ionic cadmium in a manner consistent with well-defined Cd(2+)-elicited responses reported for in vivo systems. However, one unique finding was that the transepithelial electrical resistance and tight junction sealing strands were altered as a result of Cd2+ exposure at micromolar concentrations. These alte...

Quantum dots (QDs) are intensively studied and developed for the detection of toxic heavy metal ions, notably Cd2+. However, a severe drawback is that probing QDs themselves often based on highly elements, such as Pb or Cd. Here, we report one-step aqueous synthesis more benign hydrophilic AgInZnS using 3-mercaptopropionic acid ligand with high photoluminescence quantum yield up to 41%, which w...

A sensitive and selective solid phase extraction procedure for the determination of traces of Cd(II),Zn(II) and Ag(I) ions has been developed. An alumina-sodium dodecyl sulfate (SDS) coated on with2,3 Di Hydro 2,3 para tolyl Qinazoline (1 H)- 4 one (DPTQO). The influences of the analyticalparameters including pH and sample volume were investigated. Common coexisting ions did notinterfere on the...

The modified surface of Typha latifolia L. root (MSTL), as an alternative economical adsorbent, wasused for the removal of Ni (II) and Cd(II) ions from aqueous solutions. The effect of initial pH, initialconcentration of metal ion, and contact time was investigated in a batch system at room temperature.The kinetics data could be fitted well by pseudo-second-order model with correlation coeffici...

Reactions of cadmium(II) thioand selenocyanate with 4-acetylpyridine in different molar ratios and in different solvents always lead to the formation of compounds of composition Cd(NCS)2(4acetylpyridine)2 (Cd1-I) and Cd(NCSe)2(4-acetylpyridine)2 (Cd2). Both compounds are isotypic and crystallize in the monoclinic space group C2/c. In their crystal structures the Cd cations are coordinated by tw...

the application of organic sorbents for removing heavy metal from water, replacing expensive sorbents, is particularly appropriate for developing countries. to investigate the efficiency of some organic sorbents in removing of cd2+ from aqueous solution, an experiment was conducted with three organic sorbents (sunflower stalks, apple and grapevine pruning residues) and 11 initial concentration ...

Abstract Linear kinematic features (LKFs) are found everywhere in the Arctic sea‐ice cover. They strongly localized deformations often associated with formation of leads and pressure ridges. In viscous‐plastic (VP) models, simulation LKFs depends on several factors such as grid resolution, numerical solver convergence, placement variables mesh. this study, we compare two recently proposed discr...
