Investigation of melamine and cyanuric acid concentration in several brands of liquid milk and its non-carcinogenic risk assessment in adults and infants.

In this study, the melamine and cyanuric acid concentration of widely used milk brands and the probability of non-carcinogenic risk of the brands for adults and infants were investigated. These values were 1.37 mg/L, 1.

Impostor Phenomenon and L2 willingness to communicate: Testing communication anxiety and perceived L2 competence as mediators.

The Impostor Phenomenon (IP) describes experiences of perceived intellectual fraudulence despite the existence of objectively good performances, and it is a robust predictor of experiences and outcomes in higher education. We examined the role of the IP in the domain of second language (L2) acquisition by testing its relations with a robust predictor of L2 use, willingness to communicate (WTC). We collected self-reports of 400 adult Iranian L2 learners and tested the associations between the IP and WTC.

A theoretical and experimental study of polyaniline/GCE and DNA G-quadruplex conformation as an impedimetric biosensor for the determination of potassium ions.

An electrochemical aptasensor has been developed to determine K using electrochemical impedance spectroscopy. The polyaniline (PANI) coating was first electrodeposited on a GCE. Then, the potassium-selective aptamer [G(TAG)] was adsorbed through an electrostatic force between PANI and aptamer.

exploration of novel protease inhibitors against coronavirus 2019 (COVID-19).

The spread of SARS-CoV-2 has affected human health globally. Hence, it is necessary to rapidly find the drug-candidates that can be used to treat the infection. Since the main protease (M) is the key protein in the virus's life cycle, M is served as one of the critical targets of antiviral treatment.

10-(4-Phenylpiperazine-1-carbonyl)acridin-9(10H)-ones and related compounds: Synthesis, antiproliferative activity and inhibition of tubulin polymerization.

As part of our continuing search for potent inhibitors of tubulin polymerization, two novel series of 42 10-(4-phenylpiperazine-1-carbonyl)acridin-9(10H)-ones and N-benzoylated acridones were synthesized on the basis of a retrosynthetic approach. All newly synthesized compounds were tested for antiproliferative activity and interaction with tubulin. Several analogs potently inhibited tumor cell growth.
