School of Biological and Marine Sciences

Coastal managers worldwide must prepare for changes in annual wave overtopping events due to climate change and sea-level rise. Research often assesses overtopping discharges by extreme events at a sea wall crest, typically using data from physical models or empirical rules based on scaled experiments. Here, we analyse a unique 1-year field dataset of coastal wave overtopping, from SW England, to determine the number of individual waves, regardless of their size, overtopping two locations across a coastal structure. The coastal conditions causing the most frequent overtopping differ from those driving it landward, complicating hazard communications for multiuse infrastructure. These data …

The Impact Of Domed Architecture On The Architectural Character Of Western Desert Oases, Nader Mohamed Gharib, Mo’Men Abdelqader, Yousab Magdy Shafik

Mansoura Engineering Journal

The visual disharmony arising from the indiscriminate and architecturally unplanned integration of curved roofing elements, notably domes, into the built environment of the Western Desert oases has become a significant issue, particularly in the Siwa Oasis, where the adoption of domed architecture was first introduced in the village of Jafar in 1997. This research delves into a detailed study that focuses on how pivotal historical, cultural, environmental, aesthetic, functional, and technical factors have crucially shaped the widespread integration of these iconic curved roofing superstructures in the oases' architectural heritage over generations, contributing to the uniquely recognizable architectural character and sense …

Ultra-Low-Field Portable Magnetic Resonance Imaging Feasibility And Safety In Pediatric And Neonatal Extracorporeal Membrane Oxygenation: A Single-Center Year-Long Experience., Jessica S. Wallisch, Asdis Finnsdottir Wagner, John M. Daniel Iv, Allison Taber, Maura Sien, Sarah Foster, Nathan S. Artz, Timothy Zinkus, Hung-Wen Yeh, Jose A. Pineda, Patrick M. Kochanek, Sherwin S. Chan

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Despite improving outcomes, extracorporeal membrane oxygenation (ECMO) remains associated with high rates of acute brain injury, impacting survival and outcomes. Clinical imaging modalities, including computed tomography and standard-field magnetic resonance imaging (≥1.5 Tesla), have either limited early detection of ischemic-type injuries or are incompatible with ECMO, causing diagnostic delays. A Food and Drug Administration-cleared ultra-low-field portable magnetic resonance imaging (pMRI; 0.064 Tesla) has shown promise in acute brain injury detection and use with MRI-unsafe equipment, but pediatric ECMO data are limited.

METHODS: This institutional review board-approved, single-center study was conducted at a quaternary children's hospital. Neonatal and pediatric patients …

Retinol Tracing Within Murine Neural Retina Reveals Cell Type-Specific Retinol Transport And Distribution, Jianye Zhang, Zhiqian Dong, Carolline Rodrigues Menezes, Jun Wang, Jianming Shao, Budd A Tucker, Robert F Mullins, Rui Chen, Philip D Kiser, Krzysztof Palczewski

Faculty, Staff and Students Publications

11-cis-Retinal is essential for light perception in mammalian photoreceptors (PRs), and aberrations in retinoid transformations cause severe retinal diseases. Understanding these processes is crucial for combating blinding diseases. The visual cycle, operating within PRs and the retinal pigment epithelium (RPE), regenerates 11-cis-retinal to sustain light sensitivity. Retinoids are also present in Müller glia (MG), hypothesized to supply 11-cis-retinol to cone PRs and retinal ganglion cells (RGCs). To trace retinoid movement through retinal cell types, we used cell-specific knock-in of lecithin:retinol acyltransferase (LRAT), which converts retinols into stable retinyl esters (REs). Ectopic LRAT expression in murine PRs, MG, and RGCs resulted …

Depth-Variant Deconvolution Applied To Widefield Microscopy For Rapid Large-Volume Tissue Imaging, Daniel D Lee, Kevin A Telfer, Mark A J Koenis, Yim K Lee, Kevin W Namink, Brian T Saunders, Heyun Lee, Hailey Kelley, Heather S Ruiz, Joseph P Gaut, Gwendalyn J Randolph, Bernd H Zinselmeyer

2020-Current year OA Pubs

Innovations in 3D tissue imaging have revolutionized research, but limitations stemming from lengthy protocols and equipment accessibility persist. Widefield microscopy is fast and accessible but often excluded from 3D imaging workflows due to its lack of optical sectioning. Here we combine tissue clearing with a commercial depth-variant deconvolution approach that we optimized for large-volume widefield imaging. By implementing prefiltering with z-brick splitting, we achieve subnuclear axial resolution in tissues to a depth of 500 µm in multi-tile scan images. We illustrate the utility of this method in a model of ileitis and to gain a 3D perspective in thick brain …

Between Shadows and Light

The fog moved like a living thing as Evan Cole stepped out of the train station. Windmere smelled the same as it had twenty years ago—salt, rust, and old fish. The town felt shrunken, worn down, like time had been grinding it slowly into dust.

He hadn’t wanted to return. If not for his grandmother’s death, he never would have. But her house on Seabright Lane now belonged to him, and he needed to settle her affairs.

Inside the house, everything was covered in dust: her armchair, the ceramic gulls on the mantel, the photo of …
