Electrochemically Engineered PEDOT:PSS/MXene Composite Electrode for the Label‐Free Procalcitonin Detection

Advanced Materials Interfaces, EarlyView.
Procalcitonin is a key biomarker for bacterial infections, but conventional detection methods are often time‐consuming. Here, we present an electrochemical sensor based on highly conductive Ti3C2Tx MXene combined with PEDOT:PSS, enabling direct antibody immobilization, while a bovine serum albumin coating provides antifouling protection.

Peptide Receptor‐Functionalized AuNP‐Embedded Zwitterionic Biopolymeric Nanohydrogel for Electrochemical Sclerostin Sensing

Advanced Science, EarlyView.
We report an electrochemical biosensor that employs biopanning‐derived affinity peptides as selective receptors on a multifunctional chitosan–zwitterionic–gold nanoparticle (CS–ZI–AuNPs) nanohydrogel interface. The CS–ZI–AuNPs nanohydrogel exhibits antifouling properties, abundant sites for stable peptide immobilization, and efficient electrochemical ...

Pentoxifylline dose finding trial in preterm neonates with suspected late onset sepsis (PTX‐trial)

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study (PTX‐trial) is to determine the optimal dose of pentoxifylline (PTX) in preterm neonates (gestational age < 30 weeks) with (suspected) late onset sepsis (LONS). Methods The PTX‐trial is a prospective multicentre open‐label sequential dose‐optimization study with an adapted continual reassessment method.

Plasma adrenomedullin is associated with short-term mortality and vasopressor requirement in patients admitted with sepsis [PDF]

, 2014
Introduction: The incidence of death among patients admitted for severe sepsis or septic shock is high. Adrenomedullin (ADM) plays a central role in initiating the hyperdynamic response during the early stages of sepsis.

Novel Laboratory Approaches in Heavy Chain Disease With Discordant Immunoglobulin Quantitation: A Case Report and Literature Review

Journal of Clinical Laboratory Analysis, EarlyView.
In this study, we investigated a rare case of γ‐heavy chain disease (γ‐HCD) through an integrated laboratory approach. Routine protein analyses (serum protein electrophoresis, immunotyping, and serum/urine immunofixation) identified an IgG monoclonal component without detectable light chains.
