A 2024 meta-analysis of 11 publications from six countries, aggregating data from 7,048 first-time stroke patients. The study estimates a 46% overall incidence of post-stroke cognitive impairment (PSCI) and provides subgroup analyses by gender, stroke type, and comorbidities. The supplementary document was authored by Xinyu Zhang and published on figshare under a CC-BY-4.0 license.
46% of first-time stroke patients develop cognitive impairment according to this meta-analysis of 11 studies. The dataset includes subgroup analyses for factors like stroke type, age, and comorbidities. Xinyu Zhang published this systematic review on figshare in April 2026.
A dataset containing results from a study on cell type-specific alterations in fatty acid metabolism-related genes in schizophrenia. The data likely includes key genes identified from single-cell and bulk RNA-seq analysis of 9 patients and 14 controls, and a five-gene diagnostic model. The dataset was authored by Cui Zhao and last updated on 2026-04-21.
A 2026 study by Cui Zhao integrates single-cell and bulk RNA-seq data from 9 schizophrenia patients and 14 controls to investigate cell type-specific alterations in fatty acid metabolism. The dataset includes a five-gene diagnostic model for schizophrenia, validated with an area under the ROC curve of 0.856 in the training cohort. The model was further validated using an MK-801-induced mouse model of schizophrenia.
A dataset of cell type-specific fatty acid metabolism gene expression alterations in schizophrenia, derived from integrated single-cell and bulk RNA-seq data. The data was generated by Cui Zhao and published on figshare in 2026. It includes a five-gene diagnostic model validated in a mouse model.
Anna Tonda's dataset contains post-test questionnaire results from participants who interacted with a brainwave-controlled driving game. It assesses emotional and cognitive dimensions, including negative and positive states, with response percentages, participant counts per intensity level, and basic statistics. The dataset, last updated on 2026-04-22, has a maximum sample size of 20 participants and is stored in a 16.5 KB CSV file.
China-based data from 3,983 adults aged 60 and older from the China Health and Retirement Longitudinal Study (CHARLS). The dataset supports research on the association between adverse childhood experiences and motoric cognitive risk syndrome, with mediation analysis for depression and chronic pain. The supplementary material was uploaded by figshare admin karger in April 2026.
Research data from a 2026 study investigating the role of α2,6-sialylation of Integrin β3 in Human cytomegalovirus (HCMV) entry into fibroblasts. The dataset, shared by author Taowen Pan on figshare, includes results from quantitative PCR, flow cytometry, immunofluorescence, and virological assays. It supports findings on how the sialyltransferase ST6Gal1 modifies Integrin β3 to facilitate viral internalization and signaling.
370 distinct X-ray point sources detected in an extremely deep 1-megasecond survey of the Hubble Deep Field North region, performed by the Chandra X-Ray Observatory. The catalog, created by NASA HEASARC in March 2002, lists sources across four energy bands with precise positional accuracy. It reaches flux limits of approximately 3e-17 ergs cm-2 s-1 in the soft band and 2e-16 ergs cm-2 s-1 in the hard band.
A clinical dataset from a prospective observational study investigating serum irisin as a biomarker for postoperative cognitive dysfunction (POCD) in older patients undergoing hip and knee arthroplasty. The dataset, authored by Hongxia Zhang and last updated in April 2026, contains results from Spearman correlation, multifactorial logistic regression, and receiver operating characteristic analyses. It includes data on 118 patients, with POCD occurring in 37 (31.36%) of them.
37 patients (31.36%) developed postoperative cognitive dysfunction (POCD) in this prospective observational study. The dataset contains receiver operating characteristic (ROC) analysis results evaluating serum irisin levels as a predictive biomarker for POCD, authored by Hongxia Zhang and last updated in April 2026.
