Electronic Relaxation Pathways In Thio-Acridone And Thio-Coumarin: Two Heavy-Atom-Free Photosensitizers Absorbing Visible Light, Chris Acquah, Sean Hoehn, Sarah Krul, Sourav Kanti Seth, Eric Lee, Carlos E. Crespo-Hernández

Faculty Scholarship

Heavy-atom-free photosensitizers (HAF-PSs) have emerged as a new class of photosensitizers aiming to broaden their applicability and versatility across various fields of the photodynamic therapy of cancers. The strategy involves replacing the exocyclic oxygen atoms of the carbonyl groups of established biocompatible organic fluorophores with sulfur, thereby bathochromically shifting their absorption spectra and enhancing their intersystem crossing efficiencies. Despite these advancements, the photophysical attributes and electronic relaxation mechanisms of many of these HAF-PSs remain inadequately elucidated. In this study, we investigate the excited state dynamics and photochemical properties of two promising HAF-PSs, thio-coumarin and thio-acridone. Employing a combination of steady-state …

Enhancing Chemotherapy: Synergistic Action Of Cisplatin And Berberine Hydrochloride Against Osteosarcoma, Adam S. Al-Droubi, Andrea Florian

Science University Research Symposium (SURS)

Osteosarcoma, the most common type of bone cancer, is notably aggressive and prone to a rapid rate of metastasis. When the tumor is localized; the survival rate is approximately 76% and can often be treated with surgery. However, once metastasis occurs, the survival rate drops to 24% and must be treated with chemotherapy. The standard treatment for metastatic osteosarcoma typically involves combination therapeutics, with cisplatin being a key component despite its severe side effects. Unfortunately, osteosarcoma exhibits a natural resistance to chemotherapy driven by the overexpression of drug efflux pumps, DNA repair mechanisms, and apoptosis avoidance mutations. To address these …

A Reward Self-Bias Leads To More Optimal Foraging For Ourselves Than Others, Luis Sebastian Contreras-Huerta, M. Andrea Pisauro, Svenja Küchenhoff, Arno Gekiere, Campbell Le Heron, Patricia L. Lockwood, Matthew A.J. Apps

School of Psychology

People are self-biased for rewards. We place a higher value on rewards if we receive them than if other people do. However, existing work has ignored one of the most powerful theorems from behavioural ecology of how animals seek resources in everyday life, the Marginal Value Theorem (MVT), which accounts for optimal behaviour for maximising resources intake rate. Does this self-bias help humans maximise rewards when foraging for their own benefit compared to foraging for the benefit of others? Participants had to decide when to leave patches where reward intake was gradually depleting, in environments with different average reward rates. …
