auto-reactive cells-mediated immune responses are responsible for the current tissue damages during autoimmunity. accordingly, functional modulation of auto-reactive cells has been a pivotal aim in many of recent studies. in the current study, we investigated the possibility for insertion of regulatory molecules onto auto-reactive cells through exosomal nano-shuttles as a novel approach for phe...

in the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. first, governing formulation in transverse electric field mode (te) is obtained using maxwell equations. then, an algorithm based on a finite difference scheme and matrix algebra is presented. the algorithm is then implemented in a comp...

A p-tertbutylcalix[4]arene derivative was synthesized from a reaction of the diisothiocyanate p-tertbutylcalix[4]arene, obtaining crystals that were then characterized by mass spectroscopy, Raman spectroscopy, and single-crystal X-ray diffraction. The molecule presents two acid carbamothioic-n-ethoxy-methyl-ester substituent groups. Through crystallization of this compound, it was also found th...

We review the results of our recent experimental and theoretical studies gas-phase ion-molecule reactions involving He+ ion at low collision energies (Ecoll), in kB⋅(0 – 40) K range. To avoid heating ions by stray electric fields, are studied within orbit a Rydberg electron. reach down to ~0 employing merged-beam setup. In case molecule with dipole moment (e.g., ammonia), we observe strong enha...

The kinetics of the hydrogen evolution reaction (HER) at gold electrodes is affected by concentration alkali metal cations and electrolyte pH. At moderately alkaline pH, increasing cation greatly enhances HER activity. Cations are proposed to help stabilize transition state rate-determining Volmer step a favorable interaction with dissociating water molecule (*H–OHδ−–cat+).

The gas-phase reactivity of vanadium-containing dianions, NaV3O92? and its hydrated form H2NaV3O102?, were probed towards sulphur dioxide at room temperature by ion-molecule reaction (IMR) experiments in the collision cell an ion trap mass spectrometer. sequential addition two SO2 molecules to dianion leads breakage stable V3O9 backbone, resulting a charge separation process with formation new ...

Drug discovery is a difficult and time-consuming process that involves the identification of potent therapeutic | TECH VI EW I agents with good bioavailability, metabolic stability, and low toxicity. An important first step in this process is the identification of molecules that bind with high affinity and selectivity to the biological target. High-affinity ligands might be discovered by screen...
