Investigation into the effect of phenylalanine gating on anaerobic haem breakdown using the energy landscape approach.

We have recently demonstrated a novel anaerobic NADH-dependent haem breakdown reaction, which is carried out by a range of haemoproteins. The Yersinia enterocolitica protein, HemS, is the focus of further research presented in the current paper. Using conventional experimental methods, bioinformatics, and energy landscape theory (ELT), we provide new insight into the mechanism of the novel breakdown process.

Epitope mapping via in vitro deep mutational scanning methods and its applications.

Epitope mapping is a technique employed to define the region of an antigen that elicits an immune response, providing crucial insight into the structural architecture of the antigen as well as epitope-paratope interactions. With this breadth of knowledge, immunotherapies, diagnostics, and vaccines are being developed with a rational and data-supported design. Traditional epitope mapping methods are laborious, time-intensive, and often lack the ability to screen proteins in a high-throughput manner or provide high resolution.

Extracorporeal Organ Support for Burn-Injured Patients.

As mortality relating to severe acute burn injury improves, patients are surviving longer into the critical care phase, which is commonly complicated by multisystem organ failure. Extracorporeal organ support (ECOS) represents a set of potential therapeutic technologies for managing patients with organ-specific complications. This article provides a comprehensive review of the existing literature, focusing on the use of continuous kidney replacement therapy, extracorporeal membrane oxygenation, extracorporeal carbon dioxide removal, and extracorporeal blood purification.

Etiology and Outcomes of Acute Infectious Conjunctivitis in Children.

Objective: To determine the causes of conjunctivitis and whether clinical presentations and outcomes differ by pathogen.

Study Design: This multicenter, case-control study enrolled 390 children (194 cases, 196 controls) whose conjunctival samples were tested for bacterial and viral pathogens. Caregivers completed surveys tracking symptoms, antibiotic use, school attendance, and adverse events.
