Featuring measurements from 29 termite mounds of three species, quantifying external and internal structure using photogrammetry and image analysis. It includes data on epigeal volume, surface area, basal area, macro-porosity, and micro-porosity, with comparisons to water-displacement and x-ray tomography methods. The data supports improved accuracy in estimating methane emissions from termite mounds.
400 pregnant women, including 111 with gestational diabetes mellitus (GDM) and 289 with normal glucose tolerance, participated in a cross-sectional study at 24-28 weeks of gestation. The dataset contains clinical measurements, including serum cystatin C (CysC) levels, HOMA-IR for insulin resistance, age, BMI, and HbA1c. It was collected by Weijing Zhao to explore the relationship between serum CysC and GDM risk.
This dataset quantifies the effectiveness of commercial and non-commercial metal artifact reduction (MAR) techniques for computed tomography. It compares techniques from three scanner vendors (Philips, GE, Siemens) and the freely available Metal Deletion Technique (MDT) using an anthropomorphic head and neck phantom with amalgam dental implants. The primary outcome measure is the average absolute error (AAE) reduction percentage for each technique.
Comprising genetic and phenotypic data from a study of 578 maize inbreds inoculated with Sugarcane Mosaic Virus (SCMV). The study assessed virus symptom presence at 7, 10, 14, 21, 28, and 35 days after inoculation, identifying associations with genomic regions Scmv1 and Scmv2. It was authored by Timothy J. Gustafson and last updated in 2020.
United States outpatient prescription drug claims from 2007 to 2014 quantify polypharmacy across four billion patient-months. The data counts exposure incidences for combinations of up to five drug ingredients or ATC drug classes. Among patients taking any prescription drug, half are exposed to two or more drugs, and 5% are exposed to eight or more.
A cost-effectiveness analysis from a randomized controlled trial involving 600 older patients with cognitive impairment admitted for acute medical care. The study compares health and social care costs and quality-adjusted life years (QALYs) between a specialist Medical and Mental Health Unit and standard care over a 3-month follow-up period. Data includes total adjusted costs, QALY differences, and confidence intervals for 599 participants.
Financial burden estimates for nine prevalent chronic diseases in Mexico, excluding cancer, based on the 2012 National Health and Nutrition Survey. The study calculates annual expenditure per patient and total financial burden for the Ministry of Health and the Mexican Institute of Social Security. Chronic kidney disease was the most expensive condition, with annual costs per patient exceeding US$8,966.
Data from a hospital-based bone bank in Taiwan contains a 20-year retrospective review of 3,979 allografts implanted in 3,193 recipients from July 1991 to June 2011. The registry tracks allograft sources, screening test results, harvest and implantation dates, and recipient outcomes. Analysis includes infection and discard rates, comparing recipients of sterile versus contaminated allografts.
Comprising computed tomography (CT) scan data from two female woolly mammoth neonates, Lyuba and Khroma, found in Siberian permafrost. The scans provide detailed 3D information on skeletal development, dentition, and the post-mortem formation of vivianite mineral nodules. The data enables comparative osteological analysis and 3D modeling of complex anatomical structures.
Ten healthy volunteers performed 5 trials each of sit-to-walk and sit-to-stand-and-walk tasks. The dataset contains event timing, ground reaction forces, whole-body center of mass displacement, and center of pressure to extrapolated center of mass distance measurements up to the third step. It was collected to identify biomechanical parameters consistent across different rising-to-walk behaviors.
Aggregating experimental data from a study demonstrating intravascular ultrasound elastography using a dual-element transducer. It includes measurements of shear wave peak displacement and velocity to distinguish stiffness distributions in atherosclerotic arteries ex vivo, with results from gelatin phantoms and a rabbit aorta.
CT scanning and 3D digital restoration of a Middle Triassic Kapes bentoni procolophonid specimen from the Anisian Otter Sandstone of Devon, UK, reveal anatomical details like enlarged quadratojugal processes. The dataset includes the first substantial skull and anterior postcranial skeleton description for this genus, providing insight into ossification patterns and enabling its first inclusion in a cladistic analysis.
Data from synchrotron X-ray micro-fluorescence spectroscopy and X-ray absorption near edge structure analysis of soft tissues surrounding commercially pure titanium cranial implants. The research provides the first experimental evidence that minimal load-bearing titanium implants can release debris into surrounding tissue. The dataset supports investigation into surface deterioration and ion release mechanisms in the absence of macroscopic wear.
Featuring recordings from approximately 150 retinal ganglion cells, the retina's output, used to investigate population coding. It supports a statistical model that decomposes population responses into collective modes, predicting spiking activity distribution with high accuracy. The data was collected by Adrianna R. Loback and published in 2020.
Aggregating electrophysiological (EEG) recordings from 48 total participants across two studies, including individuals with Dup15q syndrome, non-syndromic autism spectrum disorder (ASD), and typically developing children. It includes computed relative power in six frequency bands (delta, beta1, beta2, etc.) for nine regions of interest. The data was collected to identify a quantitative EEG biomarker distinguishing Dup15q syndrome from other groups.
This dataset supports a study presenting a method for synthesizing a dual-labeled fluorescent antibody-drug conjugate (ADC) for targeted therapy and molecular imaging of pancreatic cancer. The research demonstrates the ADC's binding, internalization, cytotoxicity in vitro, and its efficacy in tumor detection and growth inhibition in a mouse xenograft model. The dataset includes experimental results from immunofluorescent staining, flow cytometry, and in vivo imaging.
874 patients with adenocarcinoma of the lung, each with 47 clinical data elements, form the cohort for developing a novel effectiveness metric. The E-score metric, created by author Gregory C. Bloom, incorporates statistical p-values and quality A-scores to assess the utility of biomedical data elements. This dataset from 2020 provides the foundation for testing this metric, which ranks elements like age-at-diagnosis and tobacco-use based on both outcome correlation and data quality.
Offering co-occurrence matrices quantifying pairwise mentions of 3 million terms mapped to 1 million clinical concepts. It was computed from the raw text of 20 million clinical notes spanning 19 years of data from Stanford Hospitals and Clinics.
Janaka Lagoo's 2020 systematic review analyzes 20 studies on pediatric surgical safety checklist (SSC) effectiveness and implementation. The work synthesizes evidence from a screening process that excluded 1826 of 1921 identified studies. It explores themes like compliance measurement, stakeholder-developed strategies, and parental involvement in the SSC process.
Encompassing results from a validation study of perfusion quantification using dynamic contrast-enhanced MRI with a blood pool contrast agent in seven female pigs. The study induced three stable perfusion levels and analyzed 160 regions of interest (ROIs) in the hind leg musculature. Perfusion parameters were calculated using one- and two-compartment models, with results showing a high correlation (R=0.89) between MRI-derived total flow and ultrasound probe measurements.
