Implantable memristors are considered an emerging electronic technology that can simulate brain memory function and demonstrate some promising applications in the biomedical field. However, it remains a critical challenge to enhance their long-term stability and biocompatibility in implantation environments. In this work, an implantable memristor has been successfully fabricated based on TiO using magnetron sputtering.

Cognitive impairments are frequently observed in patients with Alcohol Use Disorder (AUD). Thiamine deficiency is often found in AUD patients and has been suggested as a possible cause of cognitive impairments. While thiamine deficiency is not consistently present in all AUD patients with cognitive deficits, thiamine is traditionally prescribed to patients with AUD to treat or prevent cognitive impairment.

The unexplained association between infection and autoimmune disease is strongest for hepatitis C virus-induced cryoglobulinemic vasculitis (HCV-cryovas). To analyze its origins, we traced the evolution of pathogenic rheumatoid factor (RF) autoantibodies in four HCV-cryovas patients by deep single-cell multi-omic analysis, revealing three sources of B cell somatic mutation converged to drive the accumulation of a large disease-causing clone. A method for quantifying low-affinity binding revealed recurring antibody variable domain combinations created by V(D)J recombination that bound self-immunoglobulin G (IgG) but not viral E2 antigen.

A left-lateralized cortical reading circuit underlies successful reading and fails to engage in individuals with reading problems. Studies identifying this circuit included youth from economically advantaged backgrounds and focused on cortical, not subcortical, structures. However, among youth with low scores on reading tests who are living in the context of economic disadvantage, this brain network is actively engaged during reading, despite persistent reading problems.
