A note on the security of two improved RFID protocols

Recently, Baghery et al. [1, 2] presented some attacks on two RFID protocols, namely Yoon and Jung et al. protocols, and proposed the improved version of them. However, in this note, we show that the improved version of the Jung et al. protocol suffers from desynchronization attack and the improved version of the Yoon's protocol suffers from secret disclosure attack. The succe...

Synthesis and optimization of application of a molecular imprinted sorbent for selective determination of two pyrethroid isomers from biological sample

Introduction: Along with the extensive production and use of various pesticides for controlling pests and enhancing the production of agricultural crops, there is a growing concern about the adverse effects of these toxic materials on human health. Therefore, the development of sensitive, selective, and accurate methods for continuous assessment of pesticides concentration in occupational and e...

Estimation of peptide concentration by a modified BCA assay

Although biuret based protein assays are theoretically applicable to peptide measurement, there is a high level of inter-peptide variation, determined largely by peptide hydrophobicity. This variation in peptide reactivity can be significantly reduced by heat-denaturation of peptides at 95 °C for 5 minutes in the presence of 0.1 M NaOH containing 1% (w/v) SDS, prior to incubation for 30 min at ...
