1. Aldehyde toxicity in human oral epithelium
Abstract : Human oral epithelium is an established target for aldehyde toxicity, including from usage of tobacco, intake of foods and fluids, leaching of dental materials, and from mouth inhalation of aldehydes in the work environment. Following establishment of culture/exposure protocols for oral cell cultures, toxicity mechanisms and risk of malignant transformation from aldehyde exposure was investigated, including the metabolic defense offered by alcohol dehydrogenase 3 (ADH3) against formaldehyde toxicity.

5. Advances in Separation Science : . Molecular Imprinting: Development of Spherical Beads and Optimization of the Formulation by Chemometrics
Abstract : An intrinsic mathematical model for simulation of fixed bed chromatography was demonstrated and compared to more simplified models. The former model was shown to describe variations in the physical, kinetic, and operating parameters better than the latter ones. READ MORE
