10559501 | Beta interferon controls West Nile virus infection and pathogenesis in mice. | Studies with mice lacking the common plasma membrane receptor for type I interferon (IFN-αβR(-)(/)(-)) have revealed that IFN signaling restricts tropism, dissemination, and lethality after infection with West Nile virus (WNV) or several other pathogenic viruses. However, the specific functions of individual IFN subtyp... |
10562341 | Frontrunners of T cell activation: Initial, localized Ca2+ signals mediated by NAADP and the type 1 ryanodine receptor | The activation of T cells is the fundamental on switch for the adaptive immune system. Ca2+ signaling is essential for T cell activation and starts as initial, short-lived, localized Ca2+ signals. The second messenger nicotinic acid adenine dinucleotide phosphate (NAADP) forms rapidly upon T cell activation and stimula... |
10574949 | A missense LAMB2 mutation causes congenital nephrotic syndrome by impairing laminin secretion. | Laminin β2 is a component of laminin-521, which is an important constituent of the glomerular basement membrane (GBM). Null mutations in laminin β2 (LAMB2) cause Pierson syndrome, a severe congenital nephrotic syndrome with ocular and neurologic defects. In contrast, patients with LAMB2 missense mutations, such as R246... |
10576136 | Interleukin-33 prevents apoptosis and improves survival after experimental myocardial infarction through ST2 signaling. | BACKGROUND ST2 is an interleukin (IL)-1 receptor family member with membrane-bound (ST2L) and soluble (sST2) isoforms, and sST2 is a biomarker for poor outcome in patients with myocardial infarction (MI). IL-33, the recently discovered ligand for ST2, activates nuclear factor kappaB and thus may regulate apoptotic cell... |
10577574 | The impact of open versus closed format ICU admission practices on the outcome of high risk surgical patients: a cohort analysis | BACKGROUND In the year 2000, the organizational structure of the ICU in the Zaandam Medical Centre (ZMC) changed from an open to a closed format ICU. The objective of this study was to evaluate the effect of this organizational change on outcome in high risk surgical patients. METHODS The medical records of all consecu... |
10582939 | Induction therapy with autologous mesenchymal stem cells in living-related kidney transplants: a randomized controlled trial. | CONTEXT Antibody-based induction therapy plus calcineurin inhibitors (CNIs) reduce acute rejection rates in kidney recipients; however, opportunistic infections and toxic CNI effects remain challenging. Reportedly, mesenchymal stem cells (MSCs) have successfully treated graft-vs-host disease. OBJECTIVE To assess autolo... |
10605189 | Cerebral cortex assembly: generating and reprogramming projection neuron diversity | The mammalian cerebral cortex is responsible for the highest levels of associative, cognitive and motor functions. In the central nervous system (CNS) the cortex stands as a prime example of extreme neuronal diversity, broadly classified into excitatory projection neurons (PNs) and inhibitory interneurons (INs). We rev... |
10607877 | Mechanical modulation of receptor-ligand interactions at cell-cell interfaces. | Cell surface receptors have been extensively studied because they initiate and regulate signal transduction cascades leading to a variety of functional cellular outcomes. An important class of immune receptors (e.g., T-cell antigen receptors) whose ligands are anchored to the surfaces of other cells remain poorly under... |
10608397 | High-performance neuroprosthetic control by an individual with tetraplegia. | BACKGROUND Paralysis or amputation of an arm results in the loss of the ability to orient the hand and grasp, manipulate, and carry objects, functions that are essential for activities of daily living. Brain-machine interfaces could provide a solution to restoring many of these lost functions. We therefore tested wheth... |
10608822 | Phase locking and multiple oscillating attractors for the coupled mammalian clock and cell cycle. | Daily synchronous rhythms of cell division at the tissue or organism level are observed in many species and suggest that the circadian clock and cell cycle oscillators are coupled. For mammals, despite known mechanistic interactions, the effect of such coupling on clock and cell cycle progression, and hence its biologi... |
10617916 | Moderate effect of artemisinin-based combination therapy on transmission of Plasmodium falciparum. | Background. Artemisinin-based combination therapy (ACT) reduces microscopically confirmed gametocytemia and mosquito infection. However, molecular techniques have recently revealed high prevalences of submicroscopic gametocytemia. Our objective here was to determine the effect of sulfadoxine-pyrimethamine (SP) monother... |
10624000 | Lip movements entrain the observers’ low-frequency brain oscillations to facilitate speech intelligibility | During continuous speech, lip movements provide visual temporal signals that facilitate speech processing. Here, using MEG we directly investigated how these visual signals interact with rhythmic brain activity in participants listening to and seeing the speaker. First, we investigated coherence between oscillatory bra... |
10627801 | Loss of DExD/H box RNA helicase LGP2 manifests disparate antiviral responses. | The DExD/H box RNA helicase retinoic acid-inducible gene I (RIG-I) and the melanoma differentiation-associated gene 5 (MDA5) are key intracellular receptors that recognize virus infection to produce type I IFN. A third helicase gene, Lgp2, is homologous to Rig-I and Mda5 but lacks a caspase activation and recruitment d... |
10628767 | Three-dimensional, single-molecule fluorescence imaging beyond the diffraction limit by using a double-helix point spread function. | We demonstrate single-molecule fluorescence imaging beyond the optical diffraction limit in 3 dimensions with a wide-field microscope that exhibits a double-helix point spread function (DH-PSF). The DH-PSF design features high and uniform Fisher information and has 2 dominant lobes in the image plane whose angular orie... |
106301 | Cardiac neural crest cells contribute to the dormant multipotent stem cell in the mammalian heart | Arodent cardiac side population cell fraction formed clonal spheroids in serum-free medium, which expressed nestin, Musashi-1, and multi-drug resistance transporter gene 1, markers of undifferentiated neural precursor cells. These markers were lost following differentiation, and were replaced by the expression of neuro... |
10641162 | A unique cell division machinery in the Archaea. | In contrast to the cell division machineries of bacteria, euryarchaea, and eukaryotes, no division components have been identified in the second main archaeal phylum, Crenarchaeota. Here, we demonstrate that a three-gene operon, cdv, in the crenarchaeon Sulfolobus acidocaldarius, forms part of a unique cell division ma... |
10641715 | Modelling and rescuing neurodevelopmental defect of Down syndrome using induced pluripotent stem cells from monozygotic twins discordant for trisomy 21 | Down syndrome (trisomy 21) is the most common viable chromosomal disorder with intellectual impairment and several other developmental abnormalities. Here, we report the generation and characterization of induced pluripotent stem cells (iPSCs) derived from monozygotic twins discordant for trisomy 21 in order to elimina... |
10648422 | Programmed death-1–induced interleukin-10 production by monocytes impairs CD4+ T cell activation during HIV infection | Viral replication and microbial translocation from the gut to the blood during HIV infection lead to hyperimmune activation, which contributes to the decline in CD4+ T cell numbers during HIV infection. Programmed death-1 (PD-1) and interleukin-10 (IL-10) are both upregulated during HIV infection. Blocking interactions... |
10650521 | A general role for splicing enhancers in exon definition. | Exonic splicing enhancers (ESEs) facilitate exon definition by assisting in the recruitment of splicing factors to the adjacent intron. Here we demonstrate that suboptimal 5' and 3' splice sites are activated independently by ESEs when they are located on different exons. However, when they are situated within a single... |
SciFact — BEIR, unified schema
A normalised copy of the dataset behind the mteb task SciFact, one of the tasks of the BEIR benchmark as mteb defines it. Same queries, documents
and relevance judgements as the benchmark evaluates — reshaped into one strict schema shared by every dataset
in this collection.

Cross-check against the previous layout
This repo previously held the same dataset in BEIR's raw two-repo form (Hyukkyu/beir-scifact + Hyukkyu/beir-scifact-qrels; that layout is kept under the git tag legacy-layout). Before replacing it, the build was compared against it: corpus id set identical (5,183 documents); qrels rows per split test 339 = 339, train 919 = 919.
