A Deep-learning classifier identifies patients with clinical heart failure using whole-slide images of H&E tissue

Nirschl, Janowczyk, Peyster, Frank, Margulies, Feldman & Madabhushi
Cardiac histopathology from human patients with clinical heart failure or cadaveric donor hearts from patients without clinical heart failure. Human tissue research: Human heart tissue was procured from two separate groups of subjects: heart transplant or LVAD recipients with severe heart failure (Fal), and brain dead, organ donors with no history of heart failure (non-failing, NF). Tissue from patients with ischemic cardiomyopathy sampled infarct-free regions. No organs or tissue were procured from prisoners. Prospective informed...

Multimodal Focused Interaction Dataset

Bano & McKenna
Recording of daily life experiences from a first-person perspective has become more prevalent with the increasing availability of wearable cameras and sensors. This dataset was captured during development of a system for automatic detection of social interactions in such data streams, and in particular focused interactions in which co-present individuals, having mutual focus of attention, interact by establishing face-to-face engagement and direct conversation. Existing public datasets for social interaction captured from first person perspective tend...

Ardler Inventor Days

Loraine Clarke & Nick Taylor
Anonymised data collected from a one-day Inventor Kits workshop held as part of the EPSRC Hacking for Situated Civic Engagement projects. The dataset includes transcripts of interviews held with participants and researchers after the event. Further information about this work can be found in: Taylor, N., Clarke, L., Skelly, M. and Nevay, S. (2018). Strategies for engaging communities in creating physical civic technologies. Proceedings of CHI 2018.

An experimental and computational framework to build a dynamic protein atlas of human cell division

Cai, Hossain, Hériché, Politi, Walther, Koch, Wachsmuth, Nijmeijer, Kueblbeck, Martinic Kavur, Ladurner, Peters & Ellenberg
Image data used to build the mitotic cell atlas. This consists of three subsets: raw images, segmentation masks for the landmarks and protein concentration maps.

In toto live imaging of gastrulation and early organogenesis in the mouse embryo

Philipp Keller
The mouse embryo has long been central to the study of mammalian development; however, elucidating the cell behaviors governing gastrulation and the formation of tissues and organs remains a fundamental challenge. A major obstacle is the lack of live imaging and image analysis technologies capable of systematically following cellular dynamics across the developing embryo. We developed a light-sheet microscope that adapts itself to the dramatic changes in size, shape and optical properties of the post-implantation...

Hackathon fieldwork 2016

Nick Taylor & Loraine Clarke
Fieldnotes and interviews from six hackathons attended as part of the "Hacking for Situated Civic Engagement" project. Further information about these events can be found in: Taylor, N. and Clarke, L.(2018). Everybody’s hacking: participation and the mainstreaming of hackathons. Proceedings of CHI 2018. Due to the wording of the ethics materials used, data can only be made to researchers. Further information about the conditions for access are available from the University of Dundee by writing...

Dual spindle formation in zygotes keeps parental genomes apart in early mammalian embryos

Reichmann, Nijmeijer , Hossain , Eguren, Schneider , Politi, Roberti , Hufnagel, Hiiragi & Ellenberg
At the beginning of mammalian life the genetic material from each parent meets when the fertilized egg divides. It was previously thought that a single microtubule spindle is responsible to spatially combine the two genomes and then segregate them to create the two-cell embryo. Utilizing light-sheet microscopy, we showed that two bipolar spindles form in the zygote, which independently congress the maternal and paternal genomes. These two spindles aligned their poles prior to anaphase but...

Models of Antenatal Care: a pilot study to explore a new quality care framework

Symon
Systematic reviews (e.g. Sandall et al. 2015) have demonstrated a link between midwifery-led continuity of care models and improved Clinical, Psychosocial and Organisational (CPO) outcomes, including preterm birth and breastfeeding rates. However, the underlying causal mechanisms within these models are not understood, and trial reports rarely detail all the relevant contextual factors for the intervention and control groups. This pilot study will test the use of focus groups with service users and providers across NHS...

Figures in support of 27.5 W/m2 collection efficiency solar laser using a diffuse scattering cooling liquid

Smyth
This is the recorded data corresponding to the graphs provided in the published paper “27.5 W/m2 collection efficiency solar laser using a diffuse scattering cooling liquid”. Figure 2A: The absorption as a function of ray incident angle for 98% and 0% diffuse reflectivity. Figure 2B: Modelled solar absorption in Nd:YAG rod as a function of reflectivity of diffuse scatterer in contact with the side wall of the rod. Figure 4: Modelled laser output power as...

Timing of gene expression in a cell-fate decision system

Aymoz , Solé , Pierre , Schmitt, de Nadal, Posas & Pelet
During development, morphogens provide extracellular cues allowing cells to select a specific fate by inducing complex transcriptional programs. The mating pathway in budding yeast offers simplified settings to understand this process. Pheromone secreted by the mating partner triggers the activity of a MAPK pathway, which results in the expression of hundreds of genes. Using a dynamic expression reporter, we quantified the kinetics of gene expression in single cells upon exogenous pheromone stimulation and in the...

Confocal microscopy images

Wang
Confocal microscopy images: All of the samples after shear stress treatment were observed using Leica confocal microscopy. The images show fields of view under microscopy. Excel chart for data analysis: Bacterial counting was performed by the software Image J, and analysed using Excel.

In Toto Cell Tracking using Lightsheet Microscopy of the Neuromesodermal Progenitor Zone of the Zebrafish Tailbud from the 21st Somite Stage

Benjamin Steventon
Lightsheet microscopy has been previously used to image and directly study the process of gastrulation in a zebrafish embryo. Before now it was not possible to use this method to study late-stage somatogenesis, due to the movement of the embryo, resulting in displacement from the field of view. Here we achieve 4D lightsheet imaging with online, image based registration to maintain the field of view during long timelapses, with emphasis on the tailbud. The zebrafish...
