Parathyroid hormone receptor-1 (PTH1R) is a class B GPCR that regulates mineral ion homeostasis via parathyroid hormone (PTH) and skeletal development via parathyroid hormone-related peptide (PTHrP). While PTHrP signaling is thought to occur predominantly at the plasma membrane, PTH is considered to also signal from endosomes; however, the mechanisms that encode subcellular PTH1R actions, as well as the biological relevance of plasma membrane vs internalized PTH1R activation, remain unclear. Here, by examining the Eiken syndrome mutant R485X-PTH1R, in which C-tail truncation removes key βarrestin docking sites, we identified βarrestins as critical modulators of compartmentalized PTH1R signaling in response to endogenous …

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and a leading cause of cancer-related mortality worldwide. Despite advances in diagnosis and therapy, the prognosis for advanced HCC remains poor due to late-stage diagnosis, high recurrence rates, therapeutic resistance, and pronounced molecular heterogeneity. HCC development is driven by complex somatic gene alterations, epigenetic reprogramming, dysregulated signaling pathways, metabolic changes, and an immunosuppressive tumor microenvironment. Molecular profiling studies have identified key oncogenic pathways involved in HCC progression, including MAPK/ERK (mitogen-activated protein kinase/extracellular signal-regulated kinase), Wnt/β-catenin, PI3K/AKT/mTOR (Phosphoinositide 3-kinase/Protein Kinase B/mechanistic Target of Rapamycin), Hippo-YAP/TAZ, (Yes-associated protein/transcriptional co-activator with PDZ-binding motif) …

Circular RNAs (circRNAs) are generated by backsplicing of eukaryotic protein-coding transcripts and can regulate microRNAs and RNA binding proteins, or serve as translation templates. Their covalently closed structure confers resistance to exonuclease-mediated degradation, extending their half-life and supporting their development as RNA therapeutics. However, existing overexpression methods often yield substantial contaminating linear RNAs, limiting their utility. Here, we systematically benchmarked plasmid-based circRNA overexpression strategies in human cells, comparing spliceosome- and ribozyme-based mechanisms across constructs incorporating widely used flanking sequences. The ribozyme-based Tornado system produced the highest circRNA yield but introduced extraneous “molecular scars” into the mature product. By contrast, spliceosome-mediated …


Incipient Buckling Detection Using Nonlinear System Identification Algorithms: A Comparative Study, Raymond Andrew Swartz, Padmanabh Shridhar Desai Sep 2026

Incipient Buckling Detection Using Nonlinear System Identification Algorithms: A Comparative Study, Raymond Andrew Swartz, Padmanabh Shridhar Desai

Michigan Tech Publications

Structural health monitoring detects and characterizes damage to predict failure, but failures like buckling, which lack signs of damage, are harder to detect. Direct load measurement is costly and complex, especially for dead loads requiring copious sensors and data acquisition hardware. Vibration-based detection is a good alternative because it infers global structural characteristics with fewer sensors. This paper presents a structural health monitoring approach for the detection of incipient buckling in structures due to excessive load conditions. Existing nonlinear modeling algorithms available in commercial software platforms, such as MATLAB and other open-source toolboxes, are leveraged to make this method potentially …
