AbstractAmphibian chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), has caused the greatest known loss of biodiversity due to an infectious disease. We used Bd infection data from quantitative real-time PCR (qPCR) assays of amphibian skin swabs collected across Chile during 2008–2018 to model Bd occurrence with the aim to determine bioclimatic and anthropogenic variables associated with Bd infection. Also, we used Bd presence/absence records to identify geographical Bd high-risk areas and compare Bd prevalence and infection loads between amphibian families, ecoregions, and host ecology. Data comprised 4155 Bd-specific qPCR assays from 162 locations across a latitudinal gradient of 3700 …

The Second World Ocean Assessment Volume 1, Jason Hall-Spencer, Louise Firth

School of Biological and Marine Sciences

In its resolutions 57/141 and 58/240, the General Assembly decided to establish a regular processunder the United Nations for global reporting and assessment of the state of the marineenvironment, including socioeconomic aspects, both current and foreseeable, building on existingregional assessments. In its resolution 71/257, the Assembly recalled that the scope of thefirst cycle of the Regular Process focused on establishing a baseline and decided that the scopeof the second cycle would extend to evaluating trends and identifying gaps. The programme ofwork for the period 2017–2020 of the second cycle of the Regular Process includes the preparationby the Group of Experts …

Facing Up To Climate Change: Community Composition Varies With Aspect And Surface Temperature In The Rocky Intertidal, A. Amstutz, L. B. Firth, J. I. Spicer, M. E. Hanley

School of Biological and Marine Sciences

Marine rocky intertidal organisms are amongst those most affected by climate change with regional distributional changes observed for many species. Although often ascribed to increased sea surface temperatures, precise assessment of the local habitat conditions underpinning observed and predicted changes in community assembly is lacking. Here we examine how aspect (i.e. north-south orientation) affects intertidal community composition and how rock surface temperatures and stress responses of two dominant grazer species (Patella spp.) elucidate emergent differences. We quantified year-round temperature variation and surveyed intertidal community composition on paired natural rock gullies with Equator- (EF) and Pole-facing (PF) surfaces. We also investigated …

On The Diversity And Distribution Of A Data Deficient Habitat In A Poorly Mapped Region: The Case Of Sabellaria Alveolata L. In Ireland, Louise B. Firth, Amelia Curd, Stephen J. Hawkins, Antony M.

Data that can be used to monitor biodiversity through time are essential for conservation and management. The reef-forming worm, Sabellaria alveolata (L. 1767) is currently classed as ‘Data Deficient’ due to an imbalance in the spread of data on its distribution. Little is known about the distribution of this species around Ireland. Using data archaeology, we collated past and present distribution records and discovered that S. alveolata has a discontinuous distribution with large gaps between populations. Many regions lack data and should be targeted for sampling. Biodiversity surveys revealed that S. alveolata supported diverse epibiotic algal communities. Retrograding (declining) reefs …

Setting Tidal Forcing For Regional Modelling Of Internal Waves, Vasiliy Vlasenko, Nataliya Stashchuk

School of Biological and Marine Sciences

Two methods for setting tides in regional numerical models focussed on replication of internal waves are discussed in this paper. A traditional procedure prescribes the tidal forcing at the boundaries of the model domain. As it follows from our analysis, this method works well in some cases but does not allow to control identical generation conditions in all points of the model grid. Tidal ellipses are spatially dependent on the relative distance to the model boundaries. An alternative method for activation of tidal motions in general circulation models is to set a tidal body force on the right-hand side of …

Electrospun Fiber Scaffolds For Engineering Glial Cell Behavior To Promote Neural Regeneration, Devan L. Puhl, Jessica L. Funnell, Derek W. Nelson, Manoj K. Gottipati, Ryan J. Gilbert

Chemical and Biochemical Engineering Faculty Research & Creative Works

Electrospinning is a fabrication technique used to produce nano-or micro-diameter fibers to generate biocompatible, biodegradable scaffolds for tissue engineering applications. Electro spun fiber scaffolds are advantageous for neural regeneration because they mimic the structure of the nervous system extracellular matrix and provide contact guidance for regenerating axons. Glia are non-neuronal regulatory cells that maintain homeostasis in the healthy nervous system and regulate regeneration in the injured nervous system. Electro spun fiber scaffolds offer a wide range of characteristics, such as fiber alignment, diameter, surface nano topography, and surface chemistry that can be engineered to achieve a desired glial cell response …

Rethinking Immune Checkpoint Blockade: Beyond The T Cell, Xiuting Liu, Graham D Hogg, David G Denardo

2020-Current year OA Pubs

The clinical success of immune checkpoint inhibitors has highlighted the central role of the immune system in cancer control. Immune checkpoint inhibitors can reinvigorate anti-cancer immunity and are now the standard of care in a number of malignancies. However, research on immune checkpoint blockade has largely been framed with the central dogma that checkpoint therapies intrinsically target the T cell, triggering the tumoricidal potential of the adaptive immune system. Although T cells undoubtedly remain a critical piece of the story, mounting evidence, reviewed herein, indicates that much of the efficacy of checkpoint therapies may be attributable to the innate immune …

Disease-Modifying Therapy Prescription Patterns In People With Multiple Sclerosis By Age, Yinan Zhang, Amber Salter, Shan Jin, William J Culpepper, Gary R Cutter, Mitchell Wallin, Olaf Stuve

2020-Current year OA Pubs

BACKGROUND: Disease-modifying therapies (DMTs) for multiple sclerosis (MS) are approved for their ability to reduce disease activity, namely clinical relapses and signal changes on magnetic resonance imaging (MRI). Disease activity appears age dependent. Thus, the greatest benefit would be expected in younger people with MS (PwMS) whereas benefits in the elderly are uncertain.

METHODS: Real-world data were obtained from PwMS from the North American Research Committee on Multiple Sclerosis (NARCOMS) registry and the US Department of Veterans Affairs Multiple Sclerosis Surveillance Registry (MSSR).

RESULTS: 6948 PwMS were surveyed from NARCOMS, and the MSSR had 1719 participants. In younger adult PwMS …

Unfriendly Fire: How The Tobacco Industry Is Destroying The Future Of Our Children, Andrew Bush, Thomas Ferkol, Et Al.

2020-Current year OA Pubs

Tobacco has long been known to be one of the greatest causes of morbidity and mortality in the adults, but the effects on the foetus and young children, which are lifelong, have been less well appreciated. Developing from this are electronic nicotine delivery systems or vapes, promulgated as being less harmful than tobacco. Nicotine itself is toxic to the foetus, with permanent effects on lung structure and function. Most vapes contain nicotine, but they also contain many other compounds which are inhaled and for which there are no toxicity studies. They also contain known toxic substances, whose use is banned …
