Abstract: The present disclosure provides a substituted pyridine derivative, which can be used as a bioactive compound for inhibiting stomach cell lines and/or inducing regeneration of damaged stomach lining.

Abstract: A method for treating an oil spill includes providing a polystyrene-based sorbent in the form of polystyrene microfibers having a sorption capacity in the range of between 30 g/g to 217 g/g, measured as grams of oil sorbed per one gram of the sorbent; drenching the polystyrene microfibers in the oil spill to be treated; collecting the oil drenched polystyrene microfibers; and removing excess oil from the oil drenched polystyrene microfibers by compressing the microfibers. The method further includes dissolving the oil drenched polystyrene microfibers in a petroleum-based solvent in the form of gasoline having an octane number of ninety one, in which both the oil drenched polystyrene microfibers and the oil is soluble, thereby forming a solution comprising the gasoline having dissolved therein the polystyrene microfibers and the oil; and utilizing the solution as a feedstock for feeding a refinery.

Abstract: Polymeric nanofibers have been developed which are useful in a variety of medical and other applications, such as filtration devices, medical prosthesis, scaffolds for tissue engineering, wound dressings, controlled drug delivery systems, cosmetic skin masks, and protective clothing. These can be formed of any of a variety of different polymers, either non-degradable or degradable. In a preferred embodiment demonstrated in the following examples, nanofibers are formed of biodegradable and non biodegradable polyphosphazenes, their blends with other polyphosphazenes or with organic, inorganic/organometallic polymers as well as composite nanofibers of polyphosphazenes with nanosized particles such as hydroxyapatites.
