Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Abscess formation caused by a foreign body reaction to a poly-d, l-lactic acid (PDLLA) absorbable plate for zygomaticomaxillary complex (ZMC) fracture

Bulletin of the National Research Centre, 2022
Background The poly-d, l-lactic acid absorbable plate does not contain poly l-lactic acid, which is the main factor in foreign body reactions; therefore, with use of this plate, a foreign body reaction is unlikely.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Ionic‐Electronic Hydrogel‐Liquid Metal Composite Bilayer with Tissue‐Adaptive and Adhesive Properties for Closed‐Loop Neuroprosthetic System

Advanced Functional Materials, EarlyView.
A hydrogel–liquid metal composite peripheral nerve interface (HLB‐PNI) combines electrically durable electrodes and tissue‐adhesive hydrogel for tissue‐adaptive implantation. In nerve‐injured rats, it enables the diagnosis of sensory‐motor connectivity via stimulation and neural signal recording.

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

Advanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Renal Neoformation: A Diagnosis to Consider

Gazeta Médica, 2022
Renal granulomas related to suture material are rare and usually accidental findings in imagiological studies. A 12-year-old boy, followed-up after Anderson-Hynes pyeloplasty 7 years before, was submitted to an ultrasonography that described a solid ...

Gossypiboma, a Rare Cause of Abdominal Pain: A Case Report

Reports
Gossypiboma is a retained surgical item, most commonly gauze or sponge, inadvertently left inside a patient’s body after surgery. Although preventable, it can cause severe complications and is often underreported due to medicolegal concerns. We present a
