The current study includes the screening of indigenous extracellular laccase producing fungus from the soil, identified as Phanerochaete chrysosporiumspecies.The selected strain was applied under the optimized condition for the production of  laccase in the solid state fermentation. The effect of polyethylene glycol and Triton X-100 on the enhancement of enzyme activity and bi...

Various tannin-complexing agents have been used to study the potential adverse effects of tannins on rumen metabolism. Using a method based on turbidity formation, the binding of various tannin-complexing agents (polyvinyl polypyrrolidone (PVPP), polyethylene glycol (PEG) of molecular weights 2000 to 35,000, and polyvinyl pyrrolidone (PVP) of molecular weight 10,000, 40,000 and 360,000) to tann...

It was a pleasure to read the elegant and witty commentary by Gutierrez and Fuller [1] regarding our paper published in Shock [2] on resuscitation of rats using our aloe-derived drag-reducing polymer (DRP) solution. However, we disagree with the statement that, 'the application of physical principles to complex living organisms often requires assumptions ad absurdum.' There is always physics be...

HBs vaccines were prepared by three different methods: 1) Heat inactivation (Krugman, et.al 1971)2) Ammonium sulphate precipitation followed by column chromatography (Sephadex G-200) 3) PEG-6000 (polyethylene glycol) precipitation followed by column chromatography using Sephadex G-200. Their efficacy was studied in guinea pigs, and the results compared with commercial Japanese vaccine (Gr...

Objective- The aim of this study was to evaluate the efficacy and safety of senna as an alternative or adjunct to polyethylene glycol (PEG) solution in dogs using colonoscopy and radiography.Design - Experimental study.Animals - 20 adult mongrel healthy dogs.Procedures- Dogs were randomly allocated to receive 1 of 4 different bowel preparation regimens including PEG, senna or ...

Background: Therapeutic and diagnosis properties of radioactive gold nanoparticle (198-AuNPs) cause them to be suitable for detection and treatment of tumors.Objective: Electrical and optical properties of PEG-198AuNPs were examined in this paper. Polyethylene Glycol (PEG)-198 AuNPs can be used for treatment and diagnosis of small intestine tumors.Methods: Wireless fluorescence capsule endoscop...
