Extended-Release Buprenorphine With Bupivacaine Effectively Provides Postoperative Analgesia In A Mouse Laparotomy Model, Monika K. Huss, Amber Kerk, Renee Cotton, Helen Chum, Michael Hsieh, Katechan Jampachaisri, Patrick Sharp, Cholowat Pacharinsak

The Thai Journal of Veterinary Medicine

Multimodal analgesia is widely encouraged for major survival surgery. This facilitates lower doses of individual drugs, thereby reducing side effects. Extended-release analgesics offer sustained analgesia coverage, prevent drug dosing nadirs, and reduce stress. Studies evaluating multimodal and extended-release analgesia combinations for major survival surgery in mice are limited. We compared the analgesic effect of bupivacaine and extended-release buprenorphine (Bupi-ER) to bupivacaine and buprenorphine HCl (Bupi-HCl). We hypothesized that preoperative Bupi-ER would provide more effective analgesia than Bupi-HCl. Mice were randomly assigned to 1 of 2 treatment groups: bupivacaine (2 mg/kg, local infiltration, once) with either 1) extended-release buprenorphine (0.6 mg/kg, …

Derivation Of Adjoint Based Error Estimates For Nonlinear Ordinary Differential Equations With Application To Multistage Sir Models With Demographics, Daniel Alcala Jul 2025

Derivation Of Adjoint Based Error Estimates For Nonlinear Ordinary Differential Equations With Application To Multistage Sir Models With Demographics, Daniel Alcala

Mathematics & Statistics ETDs

Ordinary Differential Equations (ODEs) are central to the mathematical modeling of various real-world phenomena, from mechanical systems governed by Newton’s laws to epidemic dynamics described by SIR-type ODEs. Since many ODEs do not admit closed-form analytic solutions, we approximate them numerically (e.g., with Euler’s, Runge–Kutta, or other such methods). This raises the key question: How accurate are these numerical solutions? In particular, reliably estimating the error in some quantity of interest (QoI) at time T without having an exact solution is of great scientific interest.

The first main contribution of this thesis is the development and analysis of adjoint-based error …


Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk Jul 2025

Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk

Biology ETDs

Research on Physella acuta, an invasive freshwater snail, reveals insights into its parasitology, fitness, and molecular biology. Morphological and molecular analyses revealed two distinct mitogenomic lineages, local (B) and invasive (A) strains of native P. acuta, both having comparable trematode infection rates, suggesting that the low infection rates observed from A in invaded regions result from "enemy release" rather than immune incompatibility. Fitness assessments showed that while lineages A and B performed similarly under laboratory conditions, rewilding experiments revealed significantly higher fitness in lineage A. Transcriptomic profiling supported these differences, with A snails showing greater immune-related gene expression and …
