The palladium catalysed cross-coupling of organosilicon reagents with organo halides and pseudo-halides has developed over the past 30 years into an efficient and attractive carbon-carbon bond forming strategy. Extensive research within this field to expand and diversify on the scope of the organosilicon coupling reaction will continue to promote its use in the synthesis of biologically and pha...

Synthetic Lycra spandex fibers were coated with 3-methylcholanthrene (3MC) and inserted into the lumina of 104 tracheas removed from young adult inbred Syrian hamsters. Tumors appeared 3 to 21 months after implantation of these tracheal grafts in syngeneic animals. 3MC in amounts ranging from 9 to 75 microgram/fiber induced a diversity of neoplasms in tracheal epithelium, the majority of which ...

Obtaining a continuous source of normal cells or DNA from a single individual has always been a rate limiting step in biomedical research. Availability of Lymphoblastoid cell lines (LCLs) as a surrogate for isolated or cryopreserved peripheral blood lymphocytes has substantially accelerated the process of biological investigations. LCLs can be established by in vitro infection of resting B cell...

A large variety of environmental carcinogens are metabolically activated to electrophilic metabolites that can bind to nucleic acids and protein, forming covalent adducts. The formation of DNA-carcinogen adducts is thought to be a necessary step in the action of most carcinogens. Recently, a variety of new fluorescence, immunochemical, and radioactive-postlabeling procedures have been developed...

textile effluents contain different kinds of chemical dyes and many mutagenic and carcinogenic substances. discharge of these effluents into terrestrial and aquatic ecosystems causes harmful effects. in this research, decolorization of a textile effluent by nineteen different strains of fungi was investigated. removal activity of dyes was in order of   aspergillus > rhizopus > fuzarium > penici...
