Mechanical signaling involved in molecular interactions lies at the heart of materials science and biological systems, but the mechanisms involved are poorly understood. Here we use nanomechanical sensors and intact human cells to provide unique insights into the signaling pathways of connectivity networks, which deliver the ability to probe cells to produce biologically relevant, quantifiable and reproducible signals. We quantify the mechanical signals from malignant cancer cells, with 10 cells per ml in 1000-fold excess of non-neoplastic human epithelial cells. Moreover, we demonstrate that a direct link between cells and molecules creates a continuous connectivity which acts like a percolating …
Cellular Mechanisms Of Slime Gland Refilling In Pacific Hagfish (Eptatretus Stoutii), Sarah Schorno, Todd E. Gillis, Douglas S. Fudge
Cellular Mechanisms Of Slime Gland Refilling In Pacific Hagfish (Eptatretus Stoutii), Sarah Schorno, Todd E. Gillis, Douglas S. Fudge

Hagfishes use their defensive slime to ward off gill-breathing predators. Slime gland refilling is a surprisingly slow process, and previous research has shown that the composition of the slime exudate changes significantly during refilling, which likely has consequences for the functionality of the slime. This study set out to expand our understanding of slime gland refilling by examining the cellular processes involved in refilling of the glands, as well as determining where in the gland the main slime cells – the gland thread cells and gland mucous cells – arise. Slime glands were electro-stimulated to exhaust their slime stores, left …
Characterization Of Theranostic Peptides For Glioblastoma Multiforme, Aaron Mellesmoen
Characterization Of Theranostic Peptides For Glioblastoma Multiforme, Aaron Mellesmoen
All NMU Master's Theses
Glioblastoma multiforme (GBM) is a type of primary CNS tumor in which viable treatment options do not exist. Standard of care including tumor resection, chemotherapy, and radiation does little to extend the 5-year survival expectancy past 5.1%. Herein, two small-peptide molecules with inherent antitumor activity, blood-brain barrier permeability, and capability for tumor-specific drug deliverance and intraoperative visualization (termed theranostic) were of focus. Confocal microscopy was employed to characterize in vitro specificity of chlorotoxin, a 4 kDa scorpion venom peptide, and rBSG, the recombinant 25 kDa non-glycosylated extracellular domain of extracellular matrix metalloproteinase inducer (EMMPRIN; Basigin) isoform …

We have previously evaluated and reported numerous classes of linear and cyclic peptides containing hydrophobic and hydrophilic segments for intracellular delivery of multiple molecular cargos. Herein, a combination of histidine and tryptophan amino acids were designed and evaluated for their efficiency in intracellular delivery of cell-impermeable phosphopeptides and the anti-HIV drug, emtricitabine. Two new decapeptides, with linear and cyclic natures, both containing alternate tryptophan and histidine residues, were synthesized using Fmoc/tBu solid-phase chemistry. The peptides were characterized and purified by using matrix-assisted laser desorption/ionization (MALDI) spectroscopy and high-performance liquid chromatography (HPLC), respectively. These peptides did not show significant toxicity up …

Global Issues in Public Health
Obesity is a worldwide issue that can be defined as a non-communicable condition which means that it is non-infectious and non-transmissible and it is defined as having a BMI over 30 even though BMI doesn’t account for the person’s muscle mass which causes some athletes to be considered obese just because they weigh a lot for their height. Diagnosing obesity can be a long process which includes a health history being taken, a general physical exam, calculation of BMI, and measuring waist circumference. Diagnosis of obesity also involves checking for problems such as high blood pressure, variation of cholesterol levels …
