Synthesis, physicochemical characteristics and antimicrobial studies of ethyl-substituted imidazolium-based surface active ionic liquids (SAILs)

Publication date: November 2019Source: Colloid and Interface Science Communications, Volume 33Author(s): Arifa Shaheen, Rabia Arif, Ab Waheed Mir, Sumbul RehmanAbstractA series containing higher members of ethyl-substituted imidazolium-based surface active ionic liquids (SAILs) [Cneim]Br, (n = 12, 14, 16) has been synthesized by a two-step reaction pathway. They were characterized by FT-IR, 1H NMR and 13C NMR and their effect on self-aggregation behavior in aqueous solution has been examined, employing conductometric and tensiometric methods besides fluorescence measurements and UV-visible spectroscopy. The conductivity data were recorded at different temperatures and thermodynamic parameters of micelle formation such as, standard Gibbs free energy (∆Gmo), standard enthalpy (∆Hmo), standard entropy (∆Smo) were evaluated. The process of micellization is entropy driven and supported by Gibbs free energy measurements. Interfacial parameters have also been evaluated by employing surface tension technique. The SAILs were also analyzed for their antimicrobial activity by taking eleven kinds of bacterial strains.Graphical abstract

The objective of this study was to test the hypothesis that worse prognosis in blacks with MF is mediated by higher disease stage at diagnosis and by earlier disease onset in black females. METHODS: We conducted retrospective chart review of 337 patients with clinically-suspected MF seen at Johns Hopkins between 2003 and 2018, requiring biopsy-proven disease for study inclusion. Patient demographics, initial stage/percent body surface area (BSA) involvement, pathology type, flow cytometry results, and treatment regimens were recorded. RESULTS: Of 303 patients with confirmed MF, 166 (55%) were white, 107 (35%) black...

ConclusionsThe RF-EBT3 seems to be a detector suitable for measurements of the dose at the surface. This suggests that RF-EBT3 films might be good candidates as detectors for in vivo dosimetry.

Chauhan, Arun Oinam, Bhavana RaiAbstractAimThe aim of this study was to formulate isodose volume relations encompassed by isodose surfaces in Co-60 and Ir-192 HDR intracavitary brachytherapy (ICBT) of cervix carcinoma using the Total Reference Air Kerma (TRAK).BackgroundThe TRAK and isodose volumes are radioactive source related. The formulated relations can easily estimate the irradiated isodose volume if the TRAK and dose are known. The C0-60 can also be used for brachyt...
