This study aimed to evaluate the efficacy of silver sulfate (AgSO4) as a toxicant in goldfish (Carassiusauratus). One hundred and forty-seven live specimens of C. auratus were obtained and exposed to 1, 10, 100, 500, 1000 and 2000 ppm of AgSO4for 96 hours. There was one control group (no AgSO4) and three replicates. The physicochemical properties of water and the following parameters were const...

Silver nanoparticles synthesized from plant material have superior bioactivities. The purpose of this current study was to synthesis, characterize and explore the bioactive efficacy silver (Ag-NPs) using aqueous leaf extract Tageteserecta. biosynthesized Ag-NPs were characterized ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction Scanning electro...

A two-stage passive treatment approach was assessed at a bench-scale level using two Colorado Mining Influenced Waters (MIWs). The first-stage was a limestone drain with the purpose of removing iron and aluminum and mitigating the potential effects of mineral acidity. The second stage was a sulfate reducing bioreactor composed solely of 50% corn stover and 50% walnut shells by volume. The prima...

OBJECTIVES/HYPOTHESIS To determine the resorption rate and biocompatibility characteristics of novel cross-linked hydrogel ventilation tubes and varied formulations of polyester ventilation tubes in a Chinchilla model. STUDY DESIGN Animal Study. METHODS Three cross-linked glycosaminoglycan hydrogel ventilation tubes fabricated by cross-linking thiol-modified chondroitin sulfate or thiol-mod...

Ciliary neurotrophic factor (CNTF) has been purified 35,000-fold to homogeneity from rabbit sciatic nerves using its ability to promote the survival of chick embryo ciliary ganglion neurons as the bioassay. The purification involved a combination of acid treatment, ammonium sulfate fractionation, hydrophobic interaction chromatography, chromatofocusing, preparative sodium dodecyl sulfate-polyac...

Smooth (S)-lipopolysaccharide (LPS) preparations from reference and field strains of several biovars of Brucella abortus, B. melitensis, and B. suis were prepared by (i) the hot phenol-water method, (ii) hot sodium dodecyl sulfate extraction and proteinase K digestion, or (iii) dimethyl sulfoxide extraction. These S-LPS-enriched fractions were further analyzed by sodium dodecyl sulfate-polyacry...

In the course of work in the analysis of blood, the authors have employed a number of reagents for the removal of the proteins before proceeding to the determination of other constituents. Two of these, picric acid (1) and nitric acid (2)) appeared to offer peculiar advantages in the subsequent determination of chlorides and other inorganic constituents. However, it was found that the amount of...

In the present study, silver nanoparticles (AgNPs) were synthesized via biological reduction of silver nitrate using extract of the fungus Fusarium verticillioides (green chemistry principle). The synthesized nanoparticles were spherical and homogenous in size. AgNPs were coated with polyethylene glycol (PEG) 6000, sodium dodecyl sulfate (SDS), and β-cyclodextrin (β-CD). The averaged diameters ...
