In recent days Zinc oxide (ZnO) attracted much interest due to its versatibility and size dependent opto-electronic properties. ZnO flake structures have been hydrothermally synthesized in the reaction of aqueous solution of cetyl trimethyl ammonium bromide (CTAB) and NaOH at 373.15 K. It was found that, the volume of added ammonia, surfactant (CTAB), and mixed solvent play crucial roles in mor...

We examined a number of ligands with the view of inhibiting the GTPase activity of dynamin. Dynamin contains a pleckstrin homology (PH) domain that interacts with lipids. We report a series of simple lipid-like molecules that display moderate inhibitory activity. Inhibitory activity is linked to chain length and quaternarization of the terminal amine. A change in the counterion, Cl versus Br or...

The interaction of pyridine-4(-3,-2)aldoxime has been studied whit 3-bromo-N,N,N-trialkyl-2oxo(-hydroxyimino)-1-propanaminium bromide. The structure of all synthesized compounds was determined by elemental analysis as well as by physical and chemical methods. All synthesized compounds were tested for reactivation of phosphorylated acetylcholinesterase. Using fragments of the molecules (an oxime...

This communication reports the formation of complex Langmuir monolayer at the air-water interface with the water-soluble N-cetyl N,N,N-trimethyl ammonium bromide (CTAB) molecules when interacted with the stearic acid (SA) molecules. The reaction kinetics of the formation of the CTAB-SA complex was monitored by observing the surface pressure versus time graph. Multilayered LB films of this compl...

Food contaminated with fungal pathogens can cause extremely harmful effects to human even when present in low concentrations. Researchers now pay more attention towards rapid DNA extraction for the quick screening, which is highly demanded in diverse research field. Molecular description of many fungal species is identified by different molecular characteristics. Hence, the efficient isolation ...

DNA extracted from herbarium specimens is highly fragmented; therefore, it is crucial to use extraction protocols that retrieve short DNA molecules. Improvements in extraction and DNA library preparation protocols for animal remains have allowed efficient retrieval of molecules shorter than 50 bp. Here, we applied these improvements to DNA extraction protocols for herbarium specimens and evalua...

Chromium selenide (Cr2Se3) nanoparticles were prepared by hydrothermal method from Cr(NO3)3.9H2O and SeCl4 as precursors. These nanoparticles could be produced simply in the presence of cetyltrimethyl ammonium bromide, sodium dodecyl sulfate and polyethylenglycole 600 (PEG600) and 4ml of hydrazine hydrate (N2H4.H2O) at 180 ˚C for different times. By varying the reducing agent to potassium boroh...

This paper reports absorption and fluorescence spectral studies of methyl 4-[(1E,3E)-4-phenylbuta-1,3-dienyl]benzoate (1), N,N-dimethyl-N-[4-[(1E,3E)-4-phenylbuta-1,3-dienyl]phenyl]amine (2), methyl 4-[(1E,3E)-4-[4-(dimethylamino)phenyl]buta-1,3-dienyl]benzoate (3) and 1-methyl-4-[(1E,3E)-4-[4-methoxyphenyl]buta-1,3-dienyl]benzoate (4) in homogeneous media of 1,4-dioxane and 1,4-dioxane-water b...

BACKGROUND Yarrowia lipolytica is an ascomycetous dimorphic fungus that exhibits biofilm mode of growth. Earlier work has shown that biosurfactants such as rhamnolipids are efficient dispersants of bacterial biofilms. However, their effectiveness against fungal biofilms (particularly Y. lipolytica) has not been investigated. The aim of this study was to determine the effect of rhamnolipid on a ...
