Article Abstract
The monocled cobra () is among the most feared snakes in Southeast Asia due to its toxicity, which is predominantly derived from long-chain α-neurotoxins. The only specific treatment for snakebite envenoming is antivenom based on animal-derived polyclonal antibodies. Despite the lifesaving importance of these medicines, major limitations in safety, supply consistency, and efficacy create a need for improved treatments. Here, we describe the discovery and subsequent optimization of a recombinant human monoclonal immunoglobulin G antibody against α-cobratoxin using phage display technology. Affinity maturation by light chain-shuffling resulted in a significant increase in neutralization potency and efficacy. The optimized antibody prevented lethality when incubated with whole venom prior to intravenous injection. This study is the first to demonstrate neutralization of whole snake venom by a single recombinant monoclonal antibody, thus providing a tantalizing prospect of bringing recombinant antivenoms based on human monoclonal or oligoclonal antibodies to the clinic.

Cholecystectomy-induced thrombotic microangiopathy (TMA) in a postpartum patient successfully treated with eculizumab: a case report.

Background: Thrombotic microangiopathy (TMA) is a rare, life-threatening disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage. Atypical hemolytic uremic syndrome (aHUS) is even less common, comprising less than 10% of hemolytic uremic syndrome (HUS) cases. aHUS in postpartum is associated with poor maternal outcomes, with the majority of cases resulting in end-stage renal disease.

Introduction: Neoadjuvant chemoimmunotherapy has achieved overall survival (OS) benefit for patients with resectable non-small cell lung cancer (NSCLC). Here, we present outcomes after 3 years of follow-up from the first reported study of neoadjuvant atezolizumab+chemotherapy.
Methods: This open-label, multicenter single-arm investigator-initiated phase II study conducted at three US hospitals tested up to four cycles of atezolizumab, carboplatin, and nab-paclitaxel prior to surgery.

We herein report a 52-year-old woman with anti-aquaporin 4 antibody-positive neuromyelitis optica spectrum disorder (NMOSD) and idiopathic multicentric Castleman disease (iMCD) who was successfully treated with tocilizumab, a humanized anti-human interleukin (IL)-6 receptor monoclonal antibody. This is the first report of a case of coexisting NMOSD and iMCD. IL-6 is involved in the pathogenesis of both NMOSD and iMCD, and tocilizumab is effective against both diseases.

Background: Programmed death-ligand 1 (PD-L1) expression is abundant not only in malignant cells but also in infiltrating cells within the tumor microenvironment (TME) of hepatocellular carcinoma (HCC). This study explored the association between PD-L1 expression in TME and outcomes in HCC patients treated with atezolizumab plus bevacizumab (AB), emphasizing the implications of PD-L1 expression in both malignant and tumor-infiltrating cells.
Methods: This study included 72 patients with HCC who underwent percutaneous core needle liver biopsy before AB treatment between September 2020 and December 2023.
