FINDeM: A CRISPR‐based, molecular method for rapid, inexpensive and field‐deployable organism detection

Methods in Ecology and Evolution, Volume 14, Issue 12, Page 3055-3067, December 2023., 2023
Abstract The field of ecology has undergone a molecular revolution, with researchers increasingly relying on DNA‐based methods for organism detection. Unfortunately, these techniques often require expensive equipment, dedicated laboratory spaces and specialized training in molecular and computational techniques; limitations that may exclude field ...

Spatially resolved detection of small molecules from press‐dried plant tissue using MALDI imaging

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Matrix‐assisted laser desorption/ionization mass spectrometry imaging (MALDI‐MSI) is a chemical imaging method that can visualize spatial distributions of particular molecules. Plant tissue imaging has so far mostly used cryosectioning, which can be impractical for the preparation of large‐area imaging samples, such as full flower ...

Transdermal drug delivery in horses: An in vitro comparison of skin structure and permeation of two model drugs at various anatomical sites

Veterinary Dermatology, Volume 34, Issue 3, Page 235-245, June 2023., 2023
Background – Oral and parenteral drug delivery in horses can be difficult. Equine‐specific transdermal drug formulations offer improved ease of treatment; development of such formulations requires a deeper understanding of the structural and chemical tissue barrier of horse skin. Hypothesis/Objectives – To compare the structural composition and barrier

Proposition for an additional input output multiplier metric to access the value contribution of regional cluster industries

Papers in Regional Science, Volume 101, Issue 4, Page 795-809, August 2022., 2022
Abstract This paper proposes a new multiplier metric to understand the value contribution of industries. We build on the conventional input output employment and income multiplier methods familiar to policy makers and academic research communities to propose a ‘wage premium’ multiplier that facilitates focus on the quality of employment embedded in ...

Structural and compositional dimensions of phytochemical diversity in the genus Piper reflect distinct ecological modes of action

Journal of Ecology, Volume 110, Issue 1, Page 57-67, January 2022., 2022
Crude extract 1H NMR diversity synthesizes the compositional diversity and structural complexity of phytochemical mixtures. Plants can develop chemical diversity through different combinations of structural and compositional biosynthetic mechanisms; thus, methods incorporating both dimensions of phytochemical diversity can provide new theoretical ...

Chemical and microbiological stability of diluted ceftazidime in three different solutions under three storage temperatures over a 28 day period

Veterinary Dermatology, Volume 32, Issue 5, Page 456-e124, October 2021., 2021
Background – Ceftazidime (CAZ) solutions are being used based on anecdotal reports for otitis externa complicated by multidrug‐resistant Pseudomonas aeruginosa (MDR PA). The chemical and microbiological stability of these proposed compounded solutions have not been evaluated, and likely are affected by the diluent and storage duration or temperature ...
