A novel colorimetric assay for gabapentin in bulk drug and capsules has been developed via a safety-and-sustainability concerning concept. The method relied on the reaction of primary amino group of drug with non-toxic and eco-friendly genipin in totally aqueous medium to form the blue product which was subsequently measured by visible spectrophotometry at 590 nm. Under the optimized conditions...

Two varieties of agar medium (Trypticase [BBL Microbiology Systems]-serum-sorbitol-bromcresol purple agar [TSSB] and Trypticase-blood-sorbitol-CaCO3 agar [TBSCa]) indicating microbial acid production from sorbitol were tested. The media were devised for use in studies on the prevalence of sorbitol-fermenting human oral microorganisms incubated in an anaerobic or microaerophilic atmosphere conta...

Fe3O4 (Fe3O4-CS) coated with magnetic chitosan was prepared as an adsorbent for the removal of Orange I from aqueous solutions and characterized by FTIR, XRD, SEM, TEM and TGA measurements. The effects of pH, initial concentration and contact time on the adsorption of Orange I from aqueous solutions were investigated. The decoloration rate was higher than 94% in the initial concentration range ...

TiO2–FeZn nanocatalyst combined with sonolysis were used to activate peroxymonosulfate (PMS) as a highly efficient advanced oxidation process (US/TiO2–FeZn/PMS) for the decoloration of orange II dye (OII) and real textile wastewater. The characterization as-synthesized NPs was performed by SEM, FTIR, EDX XRD analyses. Optimal experimental conditions operational parameters obtained: pH = 3, 15 m...

Compounds high in antioxidant activity counteract the formation of free radicals, which are linked to many human diseases and cancers. The objectives this study were quantify hydrophilic (HAA), lipophilic (LAA), total (TAA) algae collected US Virgin Islands. three divisions Rhodophyta, Chlorophyta, Phaeophyta. We hypothesize that HAA will be greater than LAA for all species. also hypothesized P...

We present the clinical and genetic characteristics of a Japanese patient with neuropathologically confirmed familial amyotrophic lateral sclerosis/parkinsonism dementia complex (ALS/PDC). The 68-year-old proband with an 8-year history of parkinsonism and neurogenic amyotrophy and her three siblings suffering from parkinsonism associated with dementia originated from the Kii Peninsula of Japan....

Fungi are sources of several enzymes susceptible of applications in many and diverse industrial segments such as food, beverage, textile, leather, paper and pulp, animal feed and fuel industry. These microorganisms are safe, display efficient growth under industrial production conditions and are able to secrete ample quantities of enzymes. The main fungal enzymes having industrial relevance inc...

The long-term performance of a bioaugmented membrane bioreactor (MBR) containing a GAC-packed anaerobic zone for treatment of textile wastewater containing structurally different azo dyes was observed. A unique feeding strategy, consistent with the mode of evolution of separate waste streams in textile plants, was adopted to make the best use of the GAC-zone for dye removal. Dye was introduced ...
