Synthetic Antiferromagnetic Designer Nanodisks for High‐Performance Magnetic Separation

Advanced Healthcare Materials, EarlyView.
Micromagnetic‐modeling‐based design and scalable fabrication of synthetic antiferromagnet (SAF) magnetic disk particles (MDPs) using sputter deposition enable high‐performance magnetic separation. The SAF MDPs achieve high colloidal stability and magnetic responsiveness and enable efficient magnetic separation, outperforming conventional particles ...

Isolation of Pasteurella multocida and pan-drug-resistant bacteria causing nosocomial infection in a patient with multiple sclerosis: A Case Report and Literature Review [PDF]

Medical Laboratory Journal
Pasteurella species are one of the most common pathogenic bacteria in domestic animals, and they are seen more in people with weak immune systems. This research aims to investigate a case of a patient with multiple sclerosis from whose sputum Pasteurella

Interstitial N‐Strengthened Copper‐Based Bioactive Conductive Dressings Combined with Electromagnetic Fields for Enhanced Wound Healing

Advanced Healthcare Materials, EarlyView.
This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...

Repurposing of Meropenem and Nadifloxacin for Treatment of Burn Patients? [PDF]

, 2009
The escalating number of multidrug resistant pathogens has demanded the swift development of new and potent antibiotics (ref. 2). Metallo-[beta]-lactamases (MBLs) continue to evolve, rendering the latest generation of carbapenem antibiotics useless (ref.

Biologically Active Implants Prevent Mortality in a Mouse Sepsis Model

Advanced Healthcare Materials, EarlyView.
A modular, triple‐action titanium implant is developed to prevent implant‐associated infections by repelling bacteria, killing pathogens, and enhancing tissue integration. Coatings with phage cocktails targeting P. aeruginosa and S. aureus show significant bacterial reduction and improved survival in a mouse sepsis model.

Engineering Extracellular Microenvironments: The Impact of Fibrous Materials on Cell Behavior

Advanced Healthcare Materials, EarlyView.
Fibrous structures are key elements of the native extracellular matrix and crucial for directing cell behavior. This review discusses how fiber properties such as composition, diameter, and alignment affect cell responses in 2D and 3D systems. Strategies for integrating fibrous cues into engineered tissues are highlighted, and future directions for ...

Atomic‐Level Engineering of Synthetic Receptors for Enhanced Virus Detection and Removal

Advanced Healthcare Materials, EarlyView.
Advanced computational techniques are employed to design and optimize computationally designed imprinted receptors (CIRs) for virus detection and removal. CIR‐conjugated piezoelectric sensor achieves highly sensitive virus detection in water and human serum. CIR‐integrated membranes remove 100% of pathogenic viruses from contaminated water.

An Innovative “Tooth‐On‐Chip” Microfluidic Device Emulating the Structure and Physiology of the Dental Pulp Tissue

Advanced Healthcare Materials, EarlyView.
This work presents a “tooth‐on‐chip” device that mimics dental pulp tissue. By co‐culturing key cell types, it recreates vascular networks, stem cell niches, the odontoblast/dentine interface, and trigeminal innervation. This innovative platform provides a unique model of dental pulp structure and physiology, with significant potential for accelerating
