Thirteen rabbits were given repeated cadmium injections to achieve cadmium concentrations in kidney cortex ranging from 0.05 to 1 mmole Cd/kg wet weight. Another four animals served as controls. One kidney from each animal was frozen directly to -70 degrees C whereas the other kidney was kept for 24 hr at +4 degrees C in a preservative (Sachs' solution) to simulate conditions for preservation o...

This study investigates the impacts of chemical preservation on the performance of polyamide reverse osmosis membranes with respect to water permeability and solute rejection. Three preservative chemicals, namely formaldehyde, sodium metabisulfite, and 2,2-Dibromo-3-Nitrilopropionamide, were evaluated for membrane preservation at pH 3 and 7. Experimental data show that chemical preservation may...

The aim of this study was to establish and to optimize the preparation technology of whole blood internal quality control (IQC) products for blood transfusion compatibility testing. Several B-type RhD-negative blood samples collected from healthy donors were mixed. Two groups of whole blood IQC products, namely, the preservative solution group (PS group) and the saline group, were prepared. The...

Article history: Received on: 15/03/2013 Revised on: 04/04/2013 Accepted on: 01/05/2013 Available online: A selective and reproducible high performance liquid chromatographic method has been developed for the determination of granisetron hydrochloride in presence of its hydrolytic, oxidation, photodecomposition and thermal degradation products. Successful separation of granisetron from its degr...

Woods that were placed outdoors exposed to UV-induced photodegradation processes which damaged the lignin bonds in wood resulting more susceptible woods against abrasion and weathering. This circumstance led finishing by applying paint surface carried out industries at home level. Some materials not only contribute increasing aesthetics of but also increased wood's resistance harmful microorgan...

Aims: To clarify the usefulness of preservative-free ophthalmic preparations equipped with a filter. Methods: A total of 1,615 samples of in-use ophthalmic preparations were examined for microbial contamination. Results: Of 1,094 samples of preservative-containing ophthalmic preparations, 31 (2.8%) showed microbial contamination. Of 289 samples of preservative-free ophthalmic preparations witho...

Abstract Eremurus spectabilis is a new, commercially valuable specialty cut flower, but little known about the applicable treatments to extend vase-life and maintaining ornamental quality of this flower. Therefore, present study was aimed at investigating impacts nano-silver, essential oils, chemical on keeping inflorescences Foxtail lily. The were placed in different vase solutions containing ...

Fish sausage is ground fish meat, or a mixture primarily of ground fish with ground pork, together with vegetable oil, permissible preservatives, seasoning and starch. It is packed in a casing and processed. It is a semi-processed food, the time and temperature of processing of the product being not sufficient o kill all micro organisms. Thermotolerant and spore-forming bacteria survive the pro...

PURPOSE The purpose of this study was to investigate responses to toxic cellular stresses in different human ocular epithelia. METHODS Reactivity with a specific anti-P2X7 antibody was studied using confocal fluorescence microscopy on conjunctival, corneal, lens, and retinal cell lines as well as using impression cytology on human ocular cells. Activation of the P2X7 receptor by selective ago...

nitrate concentration of the soil, at the start of growing season, is high due to minerali-zation of soil organic n during the fall and the addition of n fertilizers. it may be useful to exploit this n form as much as possible. therefore, the nitrate uptake, assimilation and dry matter production of several wheat cultivars were examined in a series of experiments using a hydroponic culture syst...
