Various attempts have been made to improve Epstein Barr Virus serodiagnosis by developing convenient methods. The present study evaluated the performance of multiplexed bead assays and immunoblot based assays on automated platforms by comparing them with immunofluorescence based assays for the determination of EBV immune status. A total of 45 serum samples were included in the study. Serum samples were tested by multiplexed bead EBV assays (AtheNA Multi-Lyte, Zeus Scientific,USA) and immunoblot based assays (Euroline, Euroimmun AG, Germany) on automated platforms. Assay systems were evaluated by comparing them with immunofluorescence based assays (Zeus Scientific, USA). For EBV anti-VCA IgM, anti-VCA IgG, anti-EA and anti-EBNA, the kappa values reflecting agreements of AtheNA and IFA were 0.20, 0.54, 0.92 and 0.95 for anti-EA, anti-VCA IgG, anti-VCA IgM and anti-EBNA respectively and the agreements of Euroline and IFA were 0.53, 0.67, 0.81 and 1.000 for anti-VCA IgG, anti-EA, anti-VCA IgM and anti-EBNA respectively. The results of the study performed on a limited number of serum samples demonstrated that the multiplexed bead assays and immunoblot assays agree with the standard IFA assay for anti-EBNA IgG and anti-VCA IgM detection while the agreement is less for anti-EA and anti-VCA IgG.

Objective: Orthopedic residents are tasked with rapidly acquiring clinical and surgical skills, especially during their PGY-1 year. However, resource constraints and other factors frequently cause skills training to fall short of established guidelines. We aimed to design and evaluate a cross-institutional, month-long curriculum aimed at pooling resources to optimize training.

Background: This study aimed to examine how physician performance metrics are affected by the speed of other attendings (co-attendings) concurrently staffing the ED.
Methods: A retrospective study was conducted using patient data from two EDs between January-2018 and February-2020. Machine learning was used to predict patient length of stay (LOS) conditional on being assigned a physician of average speed, using patient- and departmental-level variables.

Methods: A qualitative study based on content analysis was conducted.
Evidence for a metal-bosonic insulator-superconductor transition in compressed sulfur.

The abrupt drop of resistance to zero at a critical temperature is a key signature of the current paradigm of the metal-superconductor transition. However, the emergence of an intermediate bosonic insulating state characterized by a resistance peak preceding the onset of the superconducting transition has challenged this traditional understanding. Notably, this phenomenon has been predominantly observed in disordered or chemically doped low-dimensional systems, raising intriguing questions about the generality of the effect and its underlying fundamental physics.

Neurotransmitter release is triggered in microseconds by Ca-binding to the Synaptotagmin-1 C-domains and by SNARE complexes that form four-helix bundles between synaptic vesicles and plasma membranes, but the coupling mechanism between Ca-sensing and membrane fusion is unknown. Release requires extension of SNARE helices into juxtamembrane linkers that precede transmembrane regions (linker zippering) and binding of the Synaptotagmin-1 CB domain to SNARE complexes through a "primary interface" comprising two regions (I and II). The Synaptotagmin-1 Ca-binding loops were believed to accelerate membrane fusion by inducing membrane curvature, perturbing lipid bilayers, or helping bridge the membranes, but SNARE complex binding through the primary interface orients the Ca-binding loops away from the fusion site, hindering these putative activities.
