Microbiological Evaluation of 4-substituted-imidazolidine Derivatives
In the present studies, two series of 4-substituted-imidazolidines (IIIa-i and IIIj,k) were synthesized by reacting different tetrahydro-di-Schiff bases (IIa-i and IIj,k) with p-diethylaminobenzaldehyde/ dimethylaminobenzaldehyde. The title compounds were evaluated for their antibacterial and antifungal actions against some selected microbes. The results of microbiological evaluation revealed that two compounds, 4-(1,3-bis(benzo[d][1,3]dioxol-5-ylmethyl)-4-methylimidazolidin-2-yl)-N,N-diethyl aniline (IIIj), 4-(1,3-bis(benzo[d][1,3]dioxol-5-ylmethyl)-4-methylimidazolidin-2-yl)-N,N-dimethyl aniline (IIIk) were good in their antibacterial as well as antifungal actions. Minimum inhibitory concentration values (MIC) of the compounds are reported.
Appointing the Pharmacological studies Schiff base from hydrazine derivative and L-Histidine as a co-ligand with complexes: cytotoxic, antimicrobial and DNA interaction efficacy
A total of four new metal complexes bearing L-Histidine as a co-ligand and Schiff base based-hydrazine as primary were prepared and assayed by mass, (NMR) resonance of nuclear magnetic, (FT ‐ IR) Fourier transform infrared, (UV ‐ Vis) visible of ultraviolet, and analysis of elemental. From the spectral study, all the mixed metal complexes acquired as a monomeric system and the center of the metal moieties are six-coordinated with octahedral structure for [M(CNO)(His) 2 ]complexes where M= Co(II), Ni(II), Cu(II) and Zn(II). The cytotoxic activity of the ligand and its metal complexes was screened after adequate affirmation from the seniority DNA linking searches. The metal complexes might link to CT-DNA through intercalation linking structure. The activities of DNA cleavage for the complexes with pBR322 DNA were inspected by electrophoresis of gel. The prepared complexes were established to enhance the cleavage of pBR322 DNA from the supercoiled form (I) to the open circular form (II) in the existence of (H 2 O 2 ) as oxidizing. In vitro the chemosusceptibility of the prepared complexes reference that the Cu(II) complex is efficient with the chosen cell lines of human tumor, and the order of in vitro anticancer efficacies is steady with the affinities of DNA-linking and complex of Cu(II) shows very less toxicity.
Transnational variation in linguistic politeness in Vietnamese : Australia and Vietnam
Over the past three decades, the Vietnamese language has undergone substantial changes, both in Vietnam, and in diasporic contexts such as Australia. Yet the nature of the variation resulting from those changes at the sociopragmatic level in expressing politeness is little researched. 
The question of whether there are differences in the politeness expressed by Vietnamese speakers living in Vietnam and Australia is the focus of this research.
