Mechanisms Of Cadmium-Induced And Epidermal Growth Factor Receptor Mutation-Driven Lung Tumorigenesis, Hsuan-Pei Lin
Theses and Dissertations--Toxicology and Cancer Biology
Cadmium (Cd) is a ubiquitous pollutant in the environment and a known carcinogen for lung cancer. Cd has been shown to act as a weak mutagen, which suggests that it may exert tumorigenic effect through non-genotoxic ways, such as epigenetic mechanisms. The goal of this project is to investigate the mechanisms of Cd carcinogenesis focusing on the role of lncRNA dysregulations. The Cd-exposed cells formed significantly more colonies in soft agar, displayed cancer stem cell (CSC)-like property and formed tumors in nude mice. Mechanistically, the lncRNA microarray analysis revealed that chronic Cd exposure dysregulates lncRNA expressions. Q-PCR analysis confirmed the …

Science-Based Regulation Of Pharmacological Substances In Competition Horses, Jacob Machin
Theses and Dissertations--Toxicology and Cancer Biology
Current testing methodologies within equine forensic toxicology focus on arbitrary thresholds and zero-tolerance policy. Modern analytical chemistry’s limits of detection are low enough that oftentimes femtogram-per-milliliter amounts of a substance can readily be identified in both blood and urine of a horse. For most pharmacologically relevant compounds, these concentrations have no relevance to pharmacological effect. It is therefore crucial that testing methodologies to determine appropriate thresholds and cut-offs be developed that are driven by biological activity rather than arbitrary limits of detection. This dissertation looks to address this by suggesting a system of calculated Effective Plasma Concentrations by which a …

The goal of this research was to investigate the effect of electrolyte and an amphoteric surfactant on the viscosity, foamability, and foam stability of sodium laurylglucosides hydroxypropyl sulfonate (SLHS), a new anionic surfactant. Different concentrations of cocamidopropyl betaine (CAPB, 0–6% w/w) and sodium chloride (NaCl, 0–3% w/w) were added into 10% w/w SLHS solution. Each formulation was evaluated for its viscosity using a viscometer, whereas the foamability and foam stability were measured using the cylinder shaking method and analyzed by response surface methodology. The result demonstrated that an increased viscosity of the mixture resulted with an increased NaCl concentration over …

The Thai Journal of Pharmaceutical Sciences
Lasianthus stipularis Blume is a medicinal plant found in the tropical rainforests of peninsular Thailand and Malaysia. Its leaves are used in traditional medicine to treat a condition called “noise in the head” (i.e., ear infections). As such infections are often caused by Gram-negative bacteria; this species of Lasianthus may have antibacterial effects. In this study, we examined the non-polar fractions from the leaves and stem bark of L. stipularis using thin-layer chromatography and high-performance liquid chromatography (HPLC). The non-polar fractions exhibited a high coumarin content, while stem bark extracts showed a high concentration of 7-hydroxy-6-methoxycoumarin when isolated by column …

Effect Of Co2 Laser Irradiation On Eudragit® L100-55, L100, And S100 Coatings To Modify Drug Release, Varin Titapiwatanakun, Wanjing Li, Simon Gaisford, Abdul W. Basit
The Thai Journal of Pharmaceutical Sciences
The aim of this work was to investigate the use of carbon dioxide (CO2) laser irradiation to modify three types of pH-dependent Eudragit® (L100-55, L100, and S100) enteric coats with the aim of modulating drug release kinetics from the tablet cores. CO2 laser irradiation causes rapid melting and resolidification/vaporization of materials locally and precisely through the absorption of infrared energy and so can potentially disrupt the barrier integrity and function of enteric coats. It was successfully utilized to shorten the lag time of drug release (T50% and T80%) during dissolution testing. These changes were mainly caused either by pore formation …

Group-Based Quantitative Structure And Activity Relationship On Benzothiazole Derivatives For Development Of Potent Anti-Cancer Compounds, Amit S. Tapkir, Sohan S. Chitlange, Ritesh P. Bhole
The Thai Journal of Pharmaceutical Sciences
To develop potent anticancer compounds using benzothiazole scaffolds group-based quantitative structure and activity relationship (GQSAR) analysis was performed on 41 reported benzothiazole derivatives for identification of structural fragments. Benzothiazole dataset was fragmented into two fragments (R1 and R2). GQSAR models were generated using multiple linear regression. GQSAR analysis revealed the presence of hydrophobic groups on R1 will potentiate anticancer activity. The generated models are giving insight into the benzothiazole structural requirements which will be optimized for design of anticancer drugs.

The Thai Journal of Pharmaceutical Sciences
Introduction: Chitosan, a biopolymer with 97% degree of deacetylation, was used herein, to synthesize an amino sugar anionic surfactant of varied alkyl chain length, using a microwave-assisted synthesis. We were also examined their properties in aqueous form. Objectives: The objectives of the study were to increase the surface activity and water solubility of chitosan derivatives. Materials and Methods: Structural features and crystallinity were confirmed using Fourier transform infrared, ¹H-nuclear magnetic resonance, and X-ray diffraction. The chitosan by itself was found to have weak surface-active properties since it has no hydrophobic segment. Results: The microwave-assisted synthesized sugar amino-based anionic surfactant, synthesis …

A new series of 1,3,4-oxadiazole derivatives (3a-j) were synthesized by reacting p-toluic benzhydrazide (1) and substituted aromatic aldehydes (2) in the presence of ceric ammonium nitrate as catalyst and dichloromethane as a solvent medium. The structures of the new compounds were assigned based on IR, 1H-NMR, and mass spectral data and further evaluated for their in vitro anti-inflammatory potential using various protein denaturation methods following bovine serum and egg albumin assay. Some tested compounds 3e, 3f, and 3i displayed moderate anti-inflammatory activity compared to the standard diclofenac sodium.
