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.

2. Dissolving the Rocks : Solubility Enhancement of Active Pharmaceutical Ingredients using Mesoporous Silica
Abstract : Poor aqueous solubility is one of the greatest barriers for new drug candidates to enter toxicology studies, let alone clinical trials. This thesis focuses on contributing to solving this problem, evaluating the oral toxicity of mesoporous silica particles, and enhancing the apparent solubility and bioavailability of active pharmaceutical ingredients in vitro and in vivo using mesoporous silica particles.

3. Toxicity of smokeless tobacco in human oral epithelium with emphasis on carcinogen metabolism and regulation of programmed cell death
Abstract : The oral mucosa is globally a common site for cancer development. Primary risk factors include tobacco smoking and alcohol consumption whereas the contribution from usage of smokeless tobacco remains debated. READ MORE

4. Toxicological studies of di-n-butyl phthalate (DBP) : Impact on the reproductive system and gut microbiota
Abstract : The potential health impact of exposure to anthropogenic chemicals has raised major concerns worldwide. Phthalates are mainly used in the plastic industry and have been associated with adverse effects in humans. Di-n-butyl phthalate (DBP) is one of the dominant phthalates with a ubiquitous presence in the environment. READ MORE

5. Proteomics informed investigation of human hepatocytes and liver tissue
Abstract : A successful drug needs to display beneficial absorption, distribution, metabolism, excretion and toxicity (ADME-Tox) profile. It is therefore important to investigate these properties during the drug discovery process. READ MORE
