Pharmacokinetics, Pharmacodynamics, Bioavailability, and Immunogenicity of Obexelimab Following Subcutaneous Administration in Healthy Japanese and Non-Japanese Volunteers.

Introduction: Obexelimab is an investigational, bifunctional, non-depleting, humanized monoclonal antibody that binds CD19 and FcγRIIb to inhibit B cells, plasmablasts, and CD19-expressing plasma cells. In clinical trials, intravenous (IV) administration of obexelimab has been well-tolerated, and demonstrated clinical activity in patients with rheumatoid arthritis, systemic lupus erythematosus, and immunoglobulin G4-related disease. This study was performed to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of obexelimab following subcutaneous (SC) administration, and compare PK/PD profiles between healthy Japanese and non-Japanese volunteers.

Nanotechnology in healthcare, and its safety and environmental risks.

Nanotechnology holds immense promise in revolutionising healthcare, offering unprecedented opportunities in diagnostics, drug delivery, cancer therapy, and combating infectious diseases. This review explores the multifaceted landscape of nanotechnology in healthcare while addressing the critical aspects of safety and environmental risks associated with its widespread application. Beginning with an introduction to the integration of nanotechnology in healthcare, we first delved into its categorisation and various materials employed, setting the stage for a comprehensive understanding of its potential.

Nanomechanical footprint of SARS-CoV-2 variants in complex with a potent nanobody by molecular simulations.

Rational design of novel antibody therapeutics against viral infections such as coronavirus relies on surface complementarity and high affinity for their effectiveness. Here, we explore an additional property of protein complexes, the intrinsic mechanical stability, in SARS-CoV-2 variants when complexed with a potent antibody. In this study, we utilized a recent implementation of the GōMartini 3 approach to investigate large conformational changes in protein complexes with a focus on the mechanostability of the receptor-binding domain (RBD) from WT, Alpha, Delta, and XBB.

Plastic Fly: What Can Tell Us about the Biological Effects and the Carcinogenic Potential of Nanopolystyrene.

Today, plastic pollution is one of the biggest threats to the environment and public health. In the tissues of exposed species, micro- and nano-fragments accumulate, leading to genotoxicity, altered metabolism, and decreased lifespan. A model to investigate the genotoxic and tumor-promoting potential of nanoplastics (NPs) is .

Whole-exome Sequencing of Atypical Parathyroid Tumors Detects Novel and Common Genes Linked to Parathyroid Tumorigenesis.

Context: Atypical parathyroid tumor (APT) represents a neoplasm characterized by histological features typical of parathyroid carcinoma (PC) but lacking local infiltration and/or distant metastasis, leading to uncertainty regarding its malignant potential.

Objective: To characterize the molecular landscape and deregulated pathways in APT.

Methods: Whole-exome sequencing (WES) was conducted on 16 APTs.
