Freeze-dried therapeutic microbubbles: stability and gas exchange

Radwa Abou-Saleh, Aileen Delaney, Nicola Ingram, Benjamin Johnson, RICHARD BUSHBY, Sally Peyman, Louisa P. Colletta, Alexander Markham & Stephen Evans
Microbubbles (MBs) are widely used as contrast agents for ultrasound imaging and have been shown to enhance therapeutic delivery. However, they are only stable in solution for a few hours after production, which limits their potential application. Freeze-drying provides long term storage, ease of transport and consistency for therapeutic preparations thereby facilitating their use in clinical settings. The ability to freeze-dry therapeutic MBs is an important development in the translation of therapeutic MBs for clinical...

It is also provided the mean-squared displacement (MSD) for the diffusion of water through the pore system of the zeolites, the hydration number of...

Second lockdown effects on crime less pronounced in England and Wales

Graham Farrell & Anthon Dixon
Dramatic changes in recorded crime rates early in the first national lockdown (March-June), were followed by crime types moved back towards, but often remaining far from, expected levels in summer 2020 (JulySeptember). Turning points in crime in August or September coincided with the reimposition of restrictions. The second national lockdown in England in November produced less pronounced overall effects than the first, but broadly in line with the predicted ‘w-model’ of repeated lockdowns. Charts show...

Data for Time-temperature superposition of the dissolution of silk fibres in the ionic liquid 1-ethyl-3-methylimidazolium acetate

Michael Ries
This study investigated the dissolution of silk multifilament fibres in the ionic liquid 1-ethyl-3-methylimidazolium acetate. The dissolution process was found to create a silk composite fibre, comprising undissolved silk multi-filaments surrounded by a coagulated silk matrix. The dissolution procedure was carried out for a range of temperatures and times. The resulting composite fibres were studied using a combination of optical microscopy, wide angle X-ray diffraction (XRD) and tensile testing. An azimuthal (alpha) XRD scan enabled...

Supporting data for “The role of membrane destabilisation and protein dynamics in BAM catalysed OMP folding”

Paul White, Samuel Haysom, Matthew Iadanza, Anna Higgins, Jonathan Machin, James Whitehouse, Charlotte Carpenter-Platt, Jim Horne, David Brockwell, Neil Ranson & Sheena Radford
The folding of β-barrel outer membrane proteins (OMPs) in Gram-negative bacteria is catalysed by the β-barrel assembly machinery (BAM). How lateral opening in the BamA β-barrel, the core component of BAM, catalyses OMP folding remains unclear, with asymmetry in the depth of BamA potentially playing a role by disrupting membrane stability. Here, we use an anti-BamA monoclonal antibody fragment (Fab1) and two disulphide-crosslinked BAM variants (lid-locked (LL), and POTRA-5-locked (P5L)) to dissect these roles. Despite...

Proximity to forest mediates trade-offs between yields and biodiversity of birds in oil palm smallholdings

Keith C Hamer, Michael A Sasu, Linda Ofosuhene, Rebecca Asare, Benjamin Ossom, Catherine L Parr, Sarah A Scriven, Winston Asante, Rosemary Addico & Jane K Hill
There is much debate about how best to mitigate the effects of agricultural expansion on biodiversity, especially in the tropics. Recent studies have emphasised that proximity to natural habitats can enhance farmland biodiversity, yet few studies have examined whether or not such proximity mediates local trade-offs between yields and biodiversity, and hence alters conclusions about the ecological benefits of alternative farming strategies. Here we examine yield-biodiversity trade-offs, focusing on birds in oil palm smallholdings at...

Testing the effectiveness of the Forest Integrity Assessment: A field-based tool for estimating the condition of tropical forest

Andrew Suggitt, Kok Yeong, Anders Lindhe, Agnes Agama, Keith Hamer, Glen Reynolds, Jane Hill & Jennifer Lucey
1. Global targets to halt biodiversity losses and mitigate climate change will require protecting rainforest beyond current protected area networks, necessitating responsible forest stewardship from a diverse range of companies, communities and private individuals. Robust assessments of forest condition are critical for successful forest management, but many existing techniques are highly technical, time-consuming, expensive, or require specialist knowledge. 2. To make assessment of tropical forests accessible to a wide range of actors, many of whom...

The mechanism and role of hydrogen in the functionalisation of carboxylic acid-protected cobalt nanoparticles - data

Barbara Farkas, Umberto Terranova & Nora H De Leeuw
High magnetic saturation of cobalt nanoparticles has attracted significant interest towards their implementation as heat-generating agents in hyperthermia treatments. Still, considerable challenges exist in adapting these metallic particles into pragmatic, functional biomaterials. Carboxylic acid coatings have been shown as an attractive functionalisation option owing to their respectable stability and biocompatibility, however, only limited information is available on the molecular mechanism leading to their formation on cobalt nanoparticles. First principles-based theoretical methods are utilised to identify...

Large herbivores suppress liana infestation in an African savanna

Tyler C. Coverdale, Ryan D. O'Connell, Matthew C. Hutchinson, Amanda Savagian, Tyler R. Kartzinel, Todd M. Palmer, Jacob R. Goheen, David J. Augustine, Mahesh Sankaran, Corina E. Tarnita & Robert M. Pringle
African savannas are the last stronghold of diverse large-mammal communities, and a major focus of savanna ecology is to understand how these animals affect the relative abundance of trees and grasses. However, savannas support diverse plant life-forms, and human-induced changes in large-herbivore assemblages—declining wildlife populations and their displacement by livestock—may cause unexpected shifts in plant community composition. We investigated how herbivory affects the prevalence of lianas (woody vines) and their impact on trees in an...

Effect of coverage on the magnetic properties of -COOH,-SH, and -NH2 ligand-protected cobalt nanoparticles - data

Barbara Farkas & Nora H De Leeuw
Functionalisation of nanoparticles is important for their use in biomedical applications, however, it can often lead to the ligand-mediated reduction of magnetic properties, and it is therefore important to distinguish between the ligands which improve desired performance, and those that reduce it. The functionalisation-induced changes in magnetisation depend on the functional group, surface arrangement, and coverage density of the chosen ligand, and have been predicted by density functional theory (DFT) calculations for -COOH,-SH, and -NH2...

Data and script for: The patterns and modes of the evolution of disparity in Mesozoic Birds

Min Wang, Graeme Lloyd, Chi Zhang & Zhonghe Zhou
The origin of birds from non-avian theropod dinosaurs is one of the greatest transitions in evolution. Shortly after diverging from other theropods in the Late Jurassic, Mesozoic birds diversified into two major clades—the Enantiornithes and Ornithuromorpha—acquiring many features previously considered unique to the crown groups along the way. Here we present a comparative phylogenetic study of the patterns and modes of Mesozoic bird skeletal morphology and limb proportions. Our results show that the major Mesozoic...
