Selective agents concentrations

D-arabinitol is a sugar alcohol that is a typical metabolite of Candida species. The hydroxy group owned by D-arabinitol can function as a reducing agent that can reduce Ag+ to AgNPs. The resulting colloid is further stabilized by the addition of a capping agent. The capping agent used in this study was a combination of chitosan 1%(w/w) and PEG 6000 1% (w/w) (2:1) v/v. The formation of AgNPs causes an increase in the surface plasmon resonance spectra of the colloid solution at a wavelength of 430 nm with a slight blue shift.

The preconcentration of metal ions present at low concentration levels in aqueous systems and the selective removal of potentially toxic metals are important applications of adsorption processes. In this study, a heptadentate dinucleating ligand was anchored to chitosan for use in adsorption studies on Zn(II), Cu(II) and Ni(II) ions.

Puerarin-coated gold nanoparticles (PUE-AuNPs) synthesized via green synthetic route, a new colorimetric sensor, efficiently detected the ciprofloxacin (CP) in tap water and cow milk samples. The PUE-AuNPs were characterized by UV-visible, FTIR, AFM, and DLS techniques and were found to be spherical with an average size of approximately 19–20 nm. FTIR spectrum confirms that functional groups such as –OH, -C=O, -CO and –C=C were responsible for the reduction of gold (III) chloride trihydrate. These functional groups acted as capping agents to form AuNPs.

DCE@urLAB is a software application for analysis of dynamic contrast-enhanced magnetic resonance imaging data (DCE-MRI). The tool incorporates a friendly graphical user interface (GUI) to interactively select and analyze a region of interest (ROI) within the image set, taking into account the tissue concentration of the contrast agent (CA) and its effect on pixel intensity.

Success rate in selection of putative transformants is mainly dependent upon the optimum concentration of selective agent. Effect of antibiotic concentrations of hygromycin (10, 20, 30 and 50 mg/L) and paromomycin (10, 20, 30 and 50 mg/L) in callusing and regeneration media on immature embryo-derived calli was evaluated using wheat variety PBW621.

The bio efficacy of selected bio control agents viz. Metarhizium anisopliae, Beauveria bassiana, Lecanicilium lecanii and Chrysoperla zastrowii against Amrasca biguttula biguttula was studied under insectary, Department of Agricultural Entomology, TNAU, Coimbatore, India during 2014-2015. Three different concentrations viz., 1 x 104 , 1 x 106 , 1 x 108 spore/ml of these each entomopathogenic fungus were tested to evaluate the effective concentration. Among the three concentrations, 1 x 108 spores/ml of L. lecanii recorded the highest mortality of 85.

Bio-enhancers such as piperine, curcumine, ginger and cow urine distillate are being seen as important adjuvant drugs to combat antimicrobial resistance and to increase efficiency of antimicrobial agents. Cow urine distillate is one of the important bio-enhancer easily available with farmer. The disposition kinetics was aimed to assess the pharmacokinetic alteration in profile of moxifloxacin, a third generation fluoroquinolone anti-microbial agent. Moxifloxacin was administered at the dose rate of 5 mg.

Plant has an innate ability to produce non-enzymatic antioxidants which have an important role in the metabolism of Reactive oxygen species (ROS). Several plants serve as the source of therapeutic agents but the properties depend on the plant nature. Thus, an evaluation of antioxidant activity is essential to determine the importance of a plant. Three plants Utleria salicifolia, Plectranthus vettiveroides and Nothapodytes nimmoniana were selected to carry out the antioxidant study.

Prodrugs, the inert derivatives of existing drugs have successfully contributed to the modification of their physicochemical properties. The improved antimicrobial potential due to enhanced lipophilicity of some of the synthesized prodrugs of antibacterial agents by various schemes has already been reported. In the current study, synthesis, characterization, and biological evaluation of some more lipid based prodrugs/- compounds of ciprofloxacin and norfloxacin has been carried out.

The in vitro antimicrobial potency of the bacteriocin AS-48 is well documented, but its clinical application requires investigation, as its toxicity could be different in in vitro (haemolytic and antibacterial activity in blood and cytotoxicity towards normal human cell lines) and in vivo (e.g. mice and zebrafish embryos) models. Overall, the results obtained are promising.

This article presented two-staged chemical precipitation for radioactive wastewater decontamination by using chemical agents. The total amount of radioactive wastewater was 35 m3 , and main radionuclides were Cs-137, Cs-134, and Co-60. Initial radioactivity concentration of the liquid waste was 2264, 17, and 9 Bq/L for Cs-137, Cs-134 and Co-60, respectively. Potassium ferrocyanide, nickel nitrate, and ferrum nitrate were selected as chemical agents at high pH levels 8e10 according to the laboratory jar tests.
