Comparison Of Pcr-Based Methods For The Detection Of Canned Tuna Species, Chloe P. Castanon, Denise Hernandez, Akshay N. Khetrapal, Rosalee S. Hellberg
Food Science Faculty Articles and Research
Canned tuna is susceptible to mislabeling due to its high consumer demand, complex global supply chains, and range of prices. DNA barcoding of a short fragment of the mitochondrial control region (CR), termed the CR mini-barcode, has been established as an effective method for tuna species identification. However, the high level of DNA degradation in canned tuna products reduces the effectiveness of this method. Therefore, this study aimed to compare CR mini-barcoding to targeted (i.e., real-time or multiplex) PCR-based methods to determine the most effective approach for canned tuna species identification. DNA was extracted in duplicate from 24 canned tuna …

Turkish Journal of Botany
Green cities comprise a variety of habitats subject to different levels of anthropogenic pressure, ranging from completely unvegetated areas to vast green spaces such as linear parks. In this scenario, cities can support different ecological processes and ecosystem functions, which vary qualitatively and quantitatively between different habitat types along the urbanization gradient. Specifically, green spaces and ruderal plants can support pollination services in urban ecosystems, providing food resources (e.g., nectar, pollen, oil), reproduction supports (copulation sites), and nesting sites for pollinators. As a result, plant species and their floral resources are important for pollinator diversity and the maintenance of the …
Editorial: Molecular Mechanisms Of Ion Channel Activation And Modulation, Meng Cui, Miao Zhang
Editorial: Molecular Mechanisms Of Ion Channel Activation And Modulation, Meng Cui, Miao Zhang
Pharmacy Faculty Articles and Research
"Ion channels are integral membrane proteins that regulate the passage of ions across cell membranes, thereby shaping processes as diverse as neuronal signaling, muscle contraction, and hormone secretion. Channel activation is typically initiated by a stimulus such as voltage, ligand binding, or mechanical stress that induces conformational changes and opens the channel pore. Beyond activation, channels are subject to fine-tuned modulation by a wide range of endogenous and exogenous agents, from lipids and neurotransmitters to pharmacological drugs. Modulators can stabilize the open, closed, or inactivated states, shift ligand affinities, or alter gating kinetics. Dissecting the structural and dynamic basis of …
Investigating The Role Of Chaperones And Sequestrases In Misfolded Protein Sequestration, Sarah Rose Rolli
Investigating The Role Of Chaperones And Sequestrases In Misfolded Protein Sequestration, Sarah Rose Rolli
Dissertations (1934 -)
Protein homeostasis, or proteostasis, is responsible for a folded and functional proteome and is essential for cell survival. Proteins can misfold during stress or because of mutation. The accumulation of misfolded proteins is observed in many diseases, including Huntington’s disease. Misfolded proteins will clump together into inclusions, which can be sequestered to membrane-less compartments by proteostasis mechanisms. Several proteins, including chaperones, co-chaperones, and other proteins, have been identified as sequestrases that target inclusions and misfolded proteins to different protein quality control (PQC) compartments. The juxtanuclear quality control (JUNQ) compartment forms in the nucleus-vacuole junction in yeast cells, and several soluble …

Age-related hearing loss (ARHL) is a major public health concern, driven by the interplay of multiple factors. Here, we reveal spatiotemporal metabolic shifts in murine inner ears mirroring erythrocytes and plasma. Isotope-labeled glucose tracing demonstrates a metabolic rerouting favoring glycolysis over the pentose phosphate pathway, alongside downregulation of the tricarboxylic acid cycle, indicating impaired energy production and redox homeostasis. Accumulation of medium- and long-chain acylcarnitines further exacerbates lipotoxicity. Notably, age-dependent depletion of arginine, lysine, proline, and glycine disrupts the arginine-polyamine-urea cycle. Translationally, UK Biobank plasma metabolomics links omega-6 fatty acids, linoleic acid, glycine, and albumin to ARHL resilience, while branched-chain …

Injury To Soybean Seedlings From Alfalfa Weevil (Coleoptera: Curculionidae) Larvae, Robert L. Koch, M. Lourdes Chamorro
The Great Lakes Entomologist
Alfalfa weevil, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae), is primarily a pest of alfalfa, but it has been reported feeding on other plants, including soybean. The relatively limited literature on H. postica in soybean indicates that adults and larvae can feed on soybean, but it is not suitable for larval development and survival. There have been instances of H. postica adults moving from alfalfa to nearby soybean fields where they have inflicted significant injury to the soybean plants. Here we report an instance of H. postica larvae causing severe feeding injury to soybean. This infestation of soybean was the result of …

The Great Lakes Entomologist
Managers of northern hardwood forests in the Great Lakes region create gaps in the forest canopy of various sizes during harvesting to achieve different silvicultural objectives. Single-tree harvesting favors recruitment of shade-tolerant tree species by creating small gaps in the canopy, whereas group selection creates larger gaps that can favor shade-intolerant tree species. We evaluated changes in carabid beetle abundance and diversity in harvest-created gaps of five sizes (gap diameters of 6, 10, 20, 30, and 46 m) and uncut forests in northern Wisconsin where sugar maple (Acer saccharum) was the dominant tree species. Gaps were cut during …

Journal of Food and Drug Analysis
Plant-derived nanovesicles (PDNVs) offer a promising, biocompatible therapeutic platform. In this study, we isolatednanovesicles from protocorm-like bodies of Dendrobium officinale (PLBs-NVs) and evaluated their efficacy in dry eyedisease (DED) models. PLBs-NVs protected human corneal epithelial cells against hyperosmotic stress, supportedwound repair, and inhibited inflammation in vitro. In a desiccating stress-induced DED mouse model, topical PLBs-NVstreatment significantly restored tear secretion, reduced corneal epithelial damage, and lowered levels of proinflammatorycytokines. These results suggest that PLBs-NVs are a safe, natural, and effective therapeutic strategy for DED, sup-porting their potential for future clinical translation in ocular surface disorders.

Pulmonary Hypertension (PH) is a progressive and potentially fatal condition marked by high pulmonary arterypressure, resulting in heart failure and reduced oxygenation. Despite advancements in treatments, therapeutic optionsfor PH remain limited, particularly in cases resistant to conventional therapies. In biomedical research, nanotechnologyhas become a potential area of study, presenting novel approaches to drug delivery and tissue targeting. Nanosponges, aclass of nanoparticles with porous structures, have gained attention for their ability to encapsulate therapeutic agents,enhance drug stability, and provide controlled release. Nanosponges can be engineered to deliver vasodilators, anti-inflammatory drugs, and gene therapies directly to the pulmonary vasculature, minimizing systemic side …

Parkinson's disease (PD) is a progressive neurodegenerative disorder marked by dopaminergic neuronal loss,oxidative stress, neuroinflammation, and a-synuclein aggregation. Despite advances, current treatments only offersymptomatic relief without altering disease progression. This review aims to evaluate the therapeutic potential of plant-derived phytochemicals in PD through evidence from both in vivo and in vitro experimental models. Key findingsindicate that rodent models (e.g., MPTP, rotenone) and neuronal cell lines (e.g., SH-SY5Y) help replicate PD pathologyand mechanistic insights. Phytochemicals such as baicalein, morin, ferulic acid, and bacopa demonstrate neuroprotectiveeffects via antioxidant, anti-inflammatory, and mitochondrial-stabilizing pathways. Nanotechnology and brain orga-noids further improve translational relevance. In conclusion, …
