Urinary Antimony As A Biomarker For Differentiating Heroin And Brown Mixture Use, Shu-Mei Tsai, Yu-Han Hsiao, Yan-Zin Chang, Sai-Wai Ho

Journal of Food and Drug Analysis

Heroin is classified as a Schedule I controlled substance with severe legal consequences for its use, whereas liquid Brown Mixture (BM) is a legally available and commonly prescribed cough remedy in Taiwan. However, numerous cases of BM ingestion have been misinterpreted as heroin use because BM contains opium tincture, leading to similar urine test results. Owing to the rapid metabolism of heroin, detection of the parent drug and its primary metabolite, 6-acetylmorphine, in urine is difficult; thus, interpretation often relies on morphine concentration and the morphine-to-codeine (M/C) ratio, which can be inconclusive. In our BM analysis, the M/C ratio was …

Integrating Space Use And Demography To Support Management Of An Endangered Alpine Ungulate, Danielle J. Berger

All Graduate Theses and Dissertations, Fall 2023 to Present

The places animals choose to live affect the food they find, the dangers they face, and the weather conditions they experience. These experiences influence whether individual animals survive and reproduce, which in turn affects the size and health of animal populations. Although scientists have long believed that animal movements play an important role in population trends, there has been limited real-world evidence showing this connection. Advances in GPS tracking technology now allow researchers to follow animals over long periods and better understand how movement influences survival.

Journal of Food and Drug Analysis

Garambullo (Myrtillocactus geometrizans) is a Mexican fruit rich in bioactive phytochemicals. Its fermented extract (FEG), obtained after in vitro gastrointestinal digestion and fermentation, was evaluated in HT-29 and SW480 colorectal cancer cells. FEG reduced cell viability (IC50: 2985 and 3200 μg/mL, respectively) and induced apoptosis and necrosis. In 3D assays, FEG inhibited colony formation, with complete suppression in HT-29 cells. Molecular docking further suggested that butyric acid identified in FEG interacts with Caspase-3 and RIPK1. These findings support the antiproliferative and pro-death effects of FEG in colorectal cancer models.

Gut Microbiota-Mediated Modulation Of Circadian Rhythms: Physiological And Molecular Impacts Of Dietary Composition And Feeding Time, Yen-Chun Koh, Chun-Che Chang, Min-Hsiung Pan

Journal of Food and Drug Analysis

Circadian rhythms regulate fundamental aspects of physiology and behavior. The disruption of circadian rhythms has been associated with metabolic disorders, cardiovascular disease, obesity, and impaired immune function. Feeding behavior and gut microbiota represent two essential nodes within this regulatory network, as both are highly responsive to environmental cues such as diet composition and sleep-wake cycles. Research has shown that high-fat diets, excessive fructose, and chronic alcohol consumption perturb peripheral circadian rhythms and impair metabolic pathways, contributing to obesity and insulin resistance. Conversely, dietary interventions such as time-restricted feeding and macronutrient-specific entrainment can restore rhythmic gene expression and prevent metabolic pathologies. …

Toxic Relationships: Characterization Of A Putative Virally Encoded Toxin In The Thermophilic Archaeal Fusellovirus Ssv1, Jonathan C. Abshier, Patrizia L. Alpapara, Guasåli Tomokane, Kenneth M. Stedman

Center for Life in Extreme Environments Publications

Mechanisms for the maintenance of chronic viruses are poorly understood, particularly for archaeal viruses. Here, we identify the product of Sulfolobus spindle-shaped virus 1 (SSV1) ORF a291 as a putative virally encoded toxin required for growth inhibition but dispensable for viral replication and virion production. Viruses lacking ORF a291 replicated their genomes and formed morphologically normal spindle-shaped particles, yet failed to inhibit the growth of uninfected Saccharolobus solfataricus. Substitution of residues at a predicted N-terminal signal peptide cleavage site abolished growth suppression without affecting replication, suggesting that secretion is essential for toxin function. Despite primary sequence divergence among fusellovirus …
