Phenylethanolamine A (PEA) is a phenethanolamine member of the family of β-adrenergic agonists compounds illegally used as feed additives for growth promotion. In this study, PEA was covalently linked to carrier protein cationized bovine serum albumin (cBSA) and egg albumin (OVA). A monoclonal antibody specific for PEA was produced and characteristics of monoclonal antibody (McAb) were studied. Based on the McAb, an enzyme-linked immunosorbent assay (ELISA) for detection of PEA was developed, which showed an IC50 value of 6.25 ng mL(-1) and a detection limit of 0.19 ng mL(-1). The average recovery of PEA from spiked samples was 103.4%, which demonstrated that the matrices of meat where PEA may be found do not interfere with the assay.

The continued evolution of SARS-CoV-2 variants capable of subverting vaccine and infection-induced immunity suggests the advantage of a broadly protective vaccine against betacoronaviruses (β-CoVs). Recent studies have isolated monoclonal antibodies (mAbs) from SARS-CoV-2 recovered-vaccinated donors capable of neutralizing many variants of SARS-CoV-2 and other β-CoVs. Many of these mAbs target the conserved S2 stem region of the SARS-CoV-2 spike protein, rather than the receptor binding domain contained within S1 primarily targeted by current SARS-CoV-2 vaccines.

Antibodies are extensively used in biomedical research, clinical fields, and disease treatment. However, to enhance the reproducibility and reliability of antibody-based experiments, it is crucial to have a detailed understanding of the antibody's target specificity and epitope. In this study, we developed a high-throughput and precise epitope analysis method, DECODE (Decoding Epitope Composition by Optimized-mRNA-display, Data analysis, and Expression sequencing).

Background: Approval of proteasome inhibitors, immunomodulatory drugs, and anti-CD38 monoclonal antibodies (mAbs), such as daratumumab, has reshaped treatment patterns in patients with multiple myeloma (MM) in Japan. This retrospective study evaluated patient characteristics, treatment patterns, and trends in MM patients using Medical Data Vision, the largest electronic health records database in Japan with anonymous inpatient and outpatient health information.

Methods: Patients aged ≥18 years, with ≥2 records of an MM diagnostic and disease code and ≥1 record of MM treatment between 01 April 2008 and 30 June 2023 were included.

Epstein-Barr virus (EBV) establishes persistent infection, causes infectious mononucleosis, is a major trigger for multiple sclerosis and contributes to multiple cancers. Yet, knowledge remains incomplete about how the virus remodels host B cells to support lytic replication. We previously identified that EBV lytic replication results in selective depletion of plasma membrane (PM) B cell receptor (BCR) complexes, composed of immunoglobulin and the CD79A and CD79B signaling chains.

Division of Heart and Vascular, Metrohealth Medical Center, 2500 Metrohealth Dr, Cleveland, OH, 44109, USA.

Purpose Of Review: Eosinophilic myocarditis (EM) is a rare and heterogeneous form of inflammatory heart disease that can present with a wide range of severity. Current literature is limited to case reports or small case series that outline the evaluation process, disease course, and the nonstandardized treatments trialed. This review aims to concisely summarize the current literature on EM including an update on maintenance therapy for refractory or recurrent disease.
