AIM A crossover, randomised double blind study was undertaken in 30 healthy volunteers, in order to compare the tolerance of 2% carteolol with and without preservative in short term use. METHODS Complete ophthalmic examinations were performed before and 30, 60, and 180 minutes after instillation of one drop of the solution, and after 3 days of preservative treatment. After a 5 day washout, th...

The sudden availability of Italian stone pine (Pinus pinea L.) wood due to the infestation pathogenic fungi and insects highlighted need promote its use as a short supply chain resource in Italy other Mediterranean countries. However, durability sapwood must be enhanced if outdoor is considered. impregnability was studied following standard EN 351-1:2008, using immersion, vacuum, high-pressure ...

The postharvest vase life of cut roses was studied to determine the effects of various physiological factors that influence the vase life of cut flower. Cut roses were obtained from commercial area of Siliguri. To assess the effect of preservatives on the postharvest life of rose, cut flowers were treated with following preservative solutions: fixed amount of citric acid (CA) (300 mg/ml) and 8-...

A rationally based procedure has long been needed for assigning design adjustments to Southern Pine lumber treated with waterborne preservative. This paper attempts to develop such a procedure by evaluating a series of models to predict the short-term effects of waterborne preservative treatments on the strength of U.S. Southern Pine lumber. Input data consisted of non-parametric treated to unt...

Bacteriocins are considered to be a potential antibacterial or antibiofilm agent that can applied as preservative. In this study, bacteriocin BM173 was successfully expressed in Escherichia coli expression system and purified by 2-step method. Furthermore, it exhi...

Acidified and nonacidified Lugol iodine solution was tested under several storage temperatures and at several times as a preservative for marine bacteria. Direct counts with acridine orange showed no significant difference between glutaraldehyde- and Lugol iodine solution-preserved samples under any storage temperature when samples were counted within 1 week of collection. Specimens in long-ter...
