Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Comparison of Contrast-Enhanced Voiding Urosonography with Standard Fluoroscopic Voiding Cystography for the Diagnosis of Vesicoureteral Reflux: A single-Institute of Children

Dr. Sulaiman Al Habib Medical Journal
Contrast-enhanced voiding urosonography (ce-VUS) is widely used in Europe to diagnose vesicoureteric reflux (VUR) in children. It is highly sensitive and avoids exposure to ionizing radiation.

Diagnosis of acute pyelonephritis by contrast-enhanced ultrasonography in kidney transplant patients

, 2010
Diagnostic imaging of acute pyelonephritis (APN) in renal transplanted patients is an important clinical issue. While conventional ultrasonography (US) has a limited diagnostic role, contrast-enhanced computer tomography and magnetic resonance imaging ...

Role of Contrast-Enhanced Ultrasonography in Primary Hepatic Lymphoma

, 2010
Objective. Ultrasonography is the first examination performed for screening of hepatocellular carcinoma (HCC); contrast-enhanced ultrasonography (CEUS) can help discriminate between HCC and other lesions.

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption

Advanced Functional Materials, EarlyView.
Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed

A case of strangulated bowel obstruction in which transabdominal ultrasound was useful for preoperative diagnosis

Radiology Case Reports
A 74-year-old man presented to the emergency department with the chief complaint of abdominal pain. A computed tomography scan showed paralytic ileus. An ileostomy tube was placed, but the symptoms of bowel obstruction did not improve.

The role of contrast-enhanced gray-scale ultrasonography in the differential diagnosis of superficial lymph nodes. [PDF]

, 2010
Lymph node micrometastases are common, but too often in clinical practice lack the tools for their accurate prebiopsy detection. The gray-scale contrast-enhanced ultrasonography technique permits high-resolution imaging of both the arterial and ...

Tracking Battery Microstructural Degradation Through Directional Thermal Transport Signatures

Advanced Functional Materials, EarlyView.
In lithium‐ion batteries, heat conduction varies between the through‐plane and in‐plane directions because of the cell's layered structure. Therefore, cell degradation influences thermal conductivity in each direction uniquely due to detailed microstructural and compositional changes.

Reservoir‐Driven Neuromorphic Computing Based on Composite Rare‐Earth/Transition Metal Oxide Memristor

Advanced Functional Materials, EarlyView.
A defect‐engineered Ag/Gd2O3:Nb2O5/Pt rare earth composite oxide memristor enables stable multilevel reservoir states through pulse driven conductance modulation. Experimentally measured device responses are incorporated into a device aware reservoir computing framework for CIFAR‐100 image classification, highlighting the potential of rare earth ...
