BACKGROUND Macrolides show high minimum inhibitory concentrations (MICs) against Pseudomonas aeruginosa when tested in recommended media (cation-adjusted Muller-Hinton broth [CA-MHB]). Nevertheless, azithromycin is successfully used in cystic fibrosis patients, supposedly because of "nonantibiotic effects." METHODS CA-MHB and Roswell Park Memorial Institute (RPMI) 1640 medium (used for growin...

Polyacrylonitrile (PAN) membranes with nano-porous surface and high hydrophilicity were fabricated by addition of polyoxyethylene (40) nonylphenyl ether (IGEPAL) as an additive in the casting solution. The membranes were prepared from PAN/IGEPAL/1-Methyl-2-pyrrolidone (NMP) via phase inversion induced by immersion precipitation technique. Pure water was used as coagulation medium. The effects o...

The role of vascular permeability in the preferential accumulation of photosensitize» in tumor tissue was investigated. Two murine tumors [experimental mammary tumor carcinoma (EMT-6) and methylcholanthrene-induced rhabdomyosarcoma (MIS)] and a human bladder carci noma (EJ) were grown s.c. on the flank in athymic nude mice and analyzed for in vivo vessel permeability, vascular permeability fac...

Natural gas storage process in aquifer, due to fluid flow behavior of gas and water in the porous medium and because of their contact with each other under reservoir conditions, faces several challenges. Therefore, there should be a clear understanding of the injected gas behavior before and after the injection into the reservoir. This research simulates the natural gas storage in aquifer by us...

It has been observed that storage of softwoods in water often serves to increase their permeability to subsequent treatment with preservatives. Vasil’ev (1965), Ellwood & Ecklund (1959), Lutz e t a / . (1966) and Dunleavy & Fogarty (1971a, 1972) all associated microbial activity with this process. Dunleavy & McQuire (1970) have established that during water storage of Sitka spruce (Picea sitche...

Carbonate reservoirs are a highly heterogeneous type of reservoir characterized by the presence large amount vugs and pores. During two-phase displacement, flow regime in might be gravity segregated. The distribution pattern fluid would accelerate water downward horizontal directions, meanwhile decelerating an upward direction, resulting different oil recovery ratio. This gives rise to question...
