Erk Builds A Population Of Short-Lived Nascent Adhesions That Produce Persistent Edge Protrusion And Cell Migration, Andrew P. Shepherd, Keith R. Carney, Majid Rostami, Jakaria Shawon, Andrew Elliott, Shiela C. Samson, Sangyoon J. Han, Michelle C. Mendoza

Michigan Tech Publications

Cell migration is realized through the fast and persistent protrusion of a leading edge in the direction of movement. The actin and adhesion structures that build edge protrusions are integrated such that pro-migration signaling pathways must control both assemblies to induce protrusion. Understanding the contribution of adhesion regulation has been complicated by the inability to selectively assay the nascent adhesions that promote edge protrusion. Here, we dissect how the core RAS → RAF → MEK → ERK pathway’s control of nascent adhesions contributes to edge protrusion and cell migration by targeting an ERK FRET biosensor to adhesions and quantifying ERK’s …

Technical science and innovation

This study addresses the mathematical modelling and optimisation of a reactor for the esterification of safflower oil with n-butyl alcohol. To improve process controllability and reduce the need for numerous pilot-scale trials, an ideal-mixing continuous stirred-tank reactor (CSTR) model was adopted. Incorporating reaction kinetics, the effect of contact time on the relative viscosity of the product mixture was analysed. The modelling results indicate that achieving an acceptable degree of feedstock conversion is difficult when a single ideal-mixing reactor is used. Therefore, a CSTR cascade was proposed, and the configuration with N = 2 reactors was selected as the most appropriate …

Ai Method For Classification Of Diagnosis Of Near-Infrared Breast Lesion Images, Kaiquan Chen, Fangyang Shen, Honggang Wang, Zhengchao Dong, Jizhong Xiao, Ming Ma, Afroza Aktar, Christopher Chow, Wenxiong Zhang

Publications and Research

In near-infrared optical breast lesion screening and diagnosis systems, high-speed four-dimensional scanners can dynamically acquire tens of thousands of lesion images within a five-minute period. Currently, manual computer annotation is required to generate standard samples from these scanned breast lesion images, a process that depends heavily on physicians with clinical expertise. On average, a single physician can annotate only approximately ten samples per working day. As a result, this process is time-consuming and labor-intensive, and the collected samples often suffer from low accuracy, large variability, and limited diagnostic reliability. Several AI-based annotation tools, such as QuPath, HALO AI™, and X-AnyLabeling, …

Mechanisms Of Ventricular Catheter Obstruction, Mohamed Khalil Attie Ms, Christopher Roberts Ms, Carolyn Harris Phd

Medical Student Research Symposium

Background: Hydrocephalus is treated primarily with ventriculoperitoneal shunts, which fail over time mainly due to proximal ventricular catheter (VC) obstruction of the drainage holes. Prior computational fluid dynamics (CFD) studies based on idealized geometries have suggested that cerebrospinal fluid (CSF) preferentially enters distal holes due to lower resistance, thereby increasing the risk of obstruction at those locations. However, these models do not incorporate explanted VC data, patient-specific anatomy, or differences in catheter architecture.

Methods: To evaluate whether flow distribution matches failure sites, we compared obstruction patterns from 30 explanted catheters with CFD simulations of four commercial VC designs. For every …

The Stability Study Of Dna-Polymer Hybrids For Nanotechnology Applications, Ethan Kuehn, Milan Jebaraj

Miners Solving for Tomorrow Research Conference

DNA nanostructures have garnered increasing interest in their application as drug delivery vehicles. However, DNA is susceptible to degradation under physiological conditions. To remedy this, we have devised a novel method to coat DNA nanostructures with the polysaccharide chitosan (a natural derivative of chitin). Chitosan binds to DNA electrostatically and inhibits nuclease activity that would normally degrade DNA in a physiological environment. We used both agarose gel electrophoresis (AGE) and atomic force microscopy (AFM) to determine the stability of DNA before and after immersion in a simulated biological environment. Physiological conditions were mimicked by incubating the DNA in cell culture …

Chemistry Faculty Research & Creative Works

Cataract is a leading cause of vision impairment worldwide and are primarily caused by oxidative stress that damages and aggregates lens proteins, leading to lens opacification. However, the eye's anatomical barriers limit the penetration and bioavailability of antioxidant therapies. To address this challenge, a dendrimer-based nanogel with a built-in reactive oxygen species (ROS)-scavenging capability developed by us was employed to deliver the antioxidant N-acetylcysteine (NAC) to the lens. NAC was loaded into a generation-5 PEGylated poly(amidoamine) dendrimer (G5-PEG-TK, termed the GPT) nanogel. The resulting NAC-GPT was characterized for its ROS-scavenging activity, bioavailability, and corneal permeability. The efficacy of NAC-GPT was …

Chemical & Biomedical Engineering Faculty Publications

Spinal cord injury (SCI) leads to a complex remodeling of the extracellular matrix (ECM), where Tenascin-C (TNC) is strongly upregulated during the early phases of the injury cascade. While TNC is known to influence neural cell behavior, its functional role and mode of presentation in guiding neuronal differentiation remains unclear. In this study, we developed a stiffness-controlled methacrylated hyaluronic acid (MeHA) hydrogel platform that mimics the mechanical properties of the spinal cord and enables defined matrix immobilization of TNC. In vivo analyses showed elevated TNC expression from day 1, with the strongest perilesional signal during the subacute period (1 week-1 …

Numerical Study Of Nutrient Mixing In Trabecular Bone In Microgravity, Disuse And Normogravity, Sagar Gharti

Doctoral Dissertations and Master's Theses

Mechanical loading is known to regulate bone remodeling by driving interstitial fluid flow which stimulates cells and drives nutrient transport within the trabecular network. In microgravity, the absence of mechanical stimulation or loading suppresses convective flow processes, causing diffusion-driven nutrient mixing and renewal, and accelerated bone loss. This thesis investigates how oscillation frequency and trabecular bone density jointly control nutrient mixing and wall shear stress within trabecular cavities.

A computational fluid dynamics (CFD) framework is developed in STAR-CCM+ using a soft-cap oscillation model that mimics cyclic compression. Three idealized trabecular morphologies are simulated across different frequencies to represent microgravity or …

Evaluation Of An Affordable Prosthetic Liner In Resource Limited Settings, Samerial Brown

Posters - 2026

The lower limb prosthesis is an important assistive technology for persons with limb amputations and differences. The interface (prosthetic liner) between the rigid prosthetic socket and the residual limb is often made of silicone, urethane or thermoplastic elastomer gel. This material provides cushioning and support as well as suspension for the transtibial (below knee) prosthetic leg. Unfortunately the cost of liners range from $3-$600. This cost precludes its use in resource limited settings such as Sri Lanka. As a result patients are fit with a foam liner which has less cushioning and suspension capabilities than a gel type liner. This …

Severity And Duration-Dependent Aortic Stiffening In A Rabbit Coarctation Model Identifies Constitutive Material Parameters As Promising Regional Biomarkers For Hypertension Progression, Arash Ghorbannia, Jamasp Azarnoosh, John F. Ladisa Jr.

Biomedical Engineering Faculty Research and Publications

Coarctation of the aorta (CoA) alters hemodynamics and drives regional remodeling, yet the influence of severity and duration on constitutive properties is undefined. We quantified mechanical responses from CoA to identify constitutive parameters capturing stiffening across clinical severities and durations. Mild (≤ 12 mmHg), intermediate (13–20 mmHg), and severe (> 20 mmHg) CoA was created in rabbits for short, long, and prolonged durations (~ 1, 3, or 22 weeks, respectively). Stress–stretch curves from proximal and distal regions were fit with multiple constitutive models (Linear Elastic, Neo-Hookean, Yeoh, Ogden, Mooney–Rivlin, Holzapfel). Model performance was evaluated by normalized RMSE and R², with …
