Correlations among lymphocyte count, white matter hyperintensity and brain atrophy in patients with ischemic stroke.

Background: White matter hyperintensity (WMH) and brain atrophy, as imaging marker of cerebral small-vessel diseases (CSVD), have a high prevalence and strong prognostic value in stroke. We aimed to explore the association between lymphocyte count, a maker of inflammation, and WMH and brain atrophy in patients with acute ischemic stroke (AIS).

Methods: A total of 727 AIS patients with lymphocyte count and brain magnetic resonance imaging data were enrolled.

Cancer incidence and the influence of immunosuppressive agents in Korean patients with systemic lupus erythematosus: a retrospective cohort study.

Background: To investigate cancer incidence and the potential influence of immunosuppressive agents in Korean systemic lupus erythematosus (SLE) patients.

Methods: We conducted a retrospective analysis utilizing data from the Korea Healthcare Bigdata Linked Platform, which integrated the National Central Cancer Registry and National Health Insurance Service databases covering the period 2008-2017. Incidence rates (IRs) per 10,000 person-years (PYs) for site-specific cancers of SLE patients were calculated using ICD-O-3 codes.

Identifying Carbon-Carbon Triple Bonds from Double Bonds via Single-Molecule Conductance.

Molecular-scale electronics focuses on understanding and utilizing charge transport through individual molecules. A key issue is the charge transport capability of a single molecule characterized by current decay. We visualize the on-site formation of conjugated polymers with varying carbon-carbon bond orders by using scanning tunneling microscopy and noncontact atomic force microscopy.

Interferon-α promotes HLA-B-restricted presentation of conventional and alternative antigens in human pancreatic β-cells.

Interferon (IFN)-α is the earliest cytokine signature observed in individuals at risk for type 1 diabetes (T1D), but the effect of IFN-α on the antigen repertoire of HLA Class I (HLA-I) in pancreatic β-cells is unknown. Here we characterize the HLA-I antigen presentation in resting and IFN-α-exposed β-cells and find that IFN-α increases HLA-I expression and expands peptide repertoire to those derived from alternative mRNA splicing, protein cis-splicing and post-translational modifications. While the resting β-cell immunopeptidome is dominated by HLA-A-restricted peptides, IFN-α largely favors HLA-B and only marginally upregulates HLA-A, translating into increased HLA-B-restricted peptide presentation and activation of HLA-B-restricted CD8 T cells.

System- and sample-agnostic isotropic three-dimensional microscopy by weakly physics-informed, domain-shift-resistant axial deblurring.

Three-dimensional subcellular imaging is essential for biomedical research, but the diffraction limit of optical microscopy compromises axial resolution, hindering accurate three-dimensional structural analysis. This challenge is particularly pronounced in label-free imaging of thick, heterogeneous tissues, where assumptions about data distribution (e.g.
