Box 14395/515; Cancer Institute, Imam-Khomeini Hospital, Tehran University of Medical Sciences, P.O. BOX 13145-158, Tehran, Iran; UT&TUMS Cancer Electrotechnique Research Center, YAS Hospital, P.O. Box 1598718311, Tehran, Iran. Electronic address:

While limited investigations have been reported on CTC elimination and its profits, recently, some new works were reported on detection followed by the destruction of CTCs. Limitations and complications of CTC capturing procedures have highly reduced the chance of selective destruction of CTCs in the bloodstream in the therapeutic guidelines of the patients. Here, we selectively deactivated the invasive function of CTCs during their circulation in the bloodstream by exposing the whole blood to pure positive electrostatic charge stimulation (PPECS).

Food Chem 2021 Mar 20;355:129626. Epub 2021 Mar 20.

Department of Stress Biology and Plant Pathology, CEBAS-CSIC, Espinardo-Murcia, Spain. Electronic address:

The yellowing of florets limits the economic and nutritional value of broccoli during postharvest. We investigated mechanisms of action of 150 nM phytosulfokine α (PSKα) for delaying florets yellowing in broccoli during cold storage. Our results showed that SUMO E3 ligase (SIZ1) gene expression was higher in florets treated with PSKα, which may prevent endogenous HO accumulation, resulting from the higher activity of superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase.

Prediction of surface tension of solution in the presence of hydrophilic silica nanoparticle and anionic surfactant by ATR-FTIR spectroscopy and chemometric methods.

Spectrochim Acta A Mol Biomol Spectrosc 2021 Mar 17;255:119697. Epub 2021 Mar 17.

Department of Chemistry, Faculty of Science, Imam Khomeini International University, Qazvin, Iran.

In the current research, an analytical method was proposed for the quantitative determination of surface tension of anionic surfactant solutions in the presence of hydrophilic silica nanoparticles using attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy and chemometric methods. The surface tension behavior of anionic surfactant solutions considerably changes by the addition of silica nanoparticles with different particle size. The spectral data of solutions were used for prediction of surface tension using two calibration methods based on support vector machine regression (SVM-R) as a non-linear algorithm and partial least squares regression (PLS-R) as a linear algorithm.
