background and objectives: bacteria, most prevalently the pseudomonas species possess high capacity to utilize and de- grade petroleum hydrocarbons and are classified as the hydrocarbonoclastic microorganisms. many species of the genus pseudomonas are notorious for their aerobic degradation capacity, extracellular enzyme production and are metabolically versatile organisms capable of utilizing ...

Aqueous glutaraldehyde has been polymerized under alkaline conditions in the presence of a surfactant to yield microspheres of varied diameters. Microbeads of a nominal 300 nm diameter, made fluorescent via fluoresceinisothiocyanate, were used as a carrier of rabbit anti-human red blood cell antibodies. Specific labeling of the human red blood cells as well as diagnostic use of these fluor...

Six fluorescent compounds were isolated and characterized in rhizomorph of A. mellea and were presented first as: F , F , F , MF , MF and MF . These compounds differed by Rf on chromatoplaque, max in UV spectra and ex, em and max in fluorescence spectra. Their GC-MS analysis indicated that F has a phenolic moiety and the other five are the benzenic derivatives. F compound was more f...

Magneto-fluorescent nanocomposites of Zn doped ferrites nanoparticles with Pt complexes for magnetic hyperthermia and fluorescent imaging.

objective(s) mesenchymal stem cells (mscs) are nonhematopoietic stromal cells that are capable of differentiating into and contribute to the regeneration of mesenchymal tissues. human mesenchymal stem cells (hmscs) are ideal targets in cell transplantation and tissue engineering. enhanced green fluorescent protein (egfp) has been an important reporter gene for gene therapy. the aim of this stud...

we assessed a collection of 47 fluorescent pseudomonas spp., some with known biological     control activity against certain soil-borne phytopathogenic fungi such as, macrophomina phaseolina, rhizoctonia solani, phytophthora nicotianae var. parasitica, pythium sp. and  fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, hcn and protease. the resu...

rabies is acutely fatal encephalitis caused by a neurotropic virus. this virus belongs to the family ofrhabdoviridae and genus of lyssavirus. the virus is almost always transmitted to human through infectedmammalian saliva. rabies is inoculated to a wound by an infected animal bite. since infection is establishedin the cns, the outcome is almost always fatal. according to the outstanding role o...

background cryptosporidium spp. is a widespread protozoan parasite involving humans and animals. objectives this study was carried out to evaluate the immunofluorescence assay (ifa) and pcr results for more accurate diagnosis of faecal specimens. patients and methods forty six faecal human specimens of cryptosporidium oocysts were examined by pcr and ifa in calgary, canada. in statistical analy...
