Response Surface Methodology (RSM) was used in the study to optimize the production of vanillin from isoeugenol through fermentation by Aspergillus niger I-1472. Three factors were studied which include amount of isoeugenol, resin (Amberlite XAD-4) and Span 80. During fermentation, isoeugenol as substrate were vortexed with Span 80 and added into the culture on Day 4. Resin (Amberlite XAD-4) wa...
Ion exchange resins were investigated for the effective recovery of platinum, palladium, and gold from a pregnant cyanide heap leach solution. Screening results indicated that strong-base anion exchange resins proved to be most effective in the recovery of these metal cyanides. Gold was selectively recovered with the use of Minix, while effective recovery of gold, platinum, and palladium over t...
objective(s):to clarify the protective effects of cichorium glandulosum (cg) extracts on thioacetamide (taa)-induced rat hepatic fibrosis. materials and methods: the dry roots of cg were smashed and percolated with 95% ethanol, and the residual was prepared into petroleum ether extract (cg-v), ethyl acetate extract (cg-vi) and n-butyl alcohol extract (cg-vii). thirty-six wistar rats were random...
a polyamine-formaldehyde resin (Amberlite IR-4) as an anion exchange resin on the gastric secretions of rats. The acid neutralizing characteristics of the resin suggested its trial in the treatment of peptic ulcer but the large volume required to remove clinical amounts of acid from solution rendered its use impractical, even though feeding experiments showed the substance to be innocuous. Howe...
Background Quality improvement should be assigned as the main mission for healthcare providers. Clinical Governance (CG) is used not only as a strategy focusing on responding to public and government’s intolerance of poor healthcare standards, but also it is implemented for quality improvement in a number of countries. This study aims to identify the key contributing factors in the implementati...

Background and Aim: To improve the implementation of clinical governance (CG) in Iran's hospitals, awareness of various aspects of its implementation and assessment is important. The aim of this study was to find out the obstacles and challenges of clinical governance implementation and assessment in Qazvin teaching hospitals. Materials and Methods: Semi-structured interviews with 17 senior man...
