Enhanced Mechanical Properties of Injectable Chitosan–Guar Gum Hydrogel Reinforced with Bacterial Cellulose Nanofibers for Tissue Engineering Applications

Advanced Engineering Materials, EarlyView.
This study presents the development and characterization of injectable nanocomposite hydrogels based on N‐succinyl chitosan, oxidized guar gum, and bacterial cellulose nanofibers. Emphasizing enhanced mechanical properties and biocompatibility, the hydrogels exhibit fast gelation, improved structural integrity, and reduced swelling. Their potential for

Constructing Covalent Organic Polymers through Dative B─N Bonds: Synthesis, Single Crystal Structures, and Physical Properties

Advanced Functional Materials, EarlyView.
Dynamic linkages are highly attractive in preparing single crystals of covalent organic polymers (COPs). Here, single crystals of two COPs CityU‐15 and CityU‐16 based on reversible B─N bonds are constructed using tetra(4‐pyridyl)tetrathiafulvalene and tetra(4‐pyridyl)porphine as monomers.

Lung ultrasound for diagnosis of pneumothorax in an infant

Journal of Pediatric Critical Care, 2016
Point-of-care ultrasound provides rapid and accurate diagnostic imaging in an acute care setting. While thoracic ultrasonography has proved to be a useful technique for adults in the emergency department and intensive care units, few studies have ...

Imbalanced Surface Charge Induced Phase Segregation in Mixed Halide Perovskites

Advanced Functional Materials, EarlyView.
The key factor determining the phase segregation in mixed halide perovskites (MHP) is the intrinsic imbalanced surface charges in the crystal lattice. MHP films with excellent crystallinity and surface morphology can suffer severe phase segregation.

Knowledge, attitude, practices, and perceived barriers to using point-of-care ultrasound by Asian primary care physicians – a mixed method study

BMC Health Services Research
Background Although research shows that point-of-care ultrasound is helpful in primary care, there is little research on point-of-care ultrasound use and the barriers to its use in Asia.

Point-of-care ultrasound used to exclude penile fracture [PDF]

, 2012
This is a case report of a superficial penile hematoma that was difficult to distinguish clinically from a penile fracture. Such cases occur with relative frequency, and because definitive treatment is an urgent surgery, timely diagnosis is essential to ...

Facet‐Junction Induced Strong Metal Support Interaction for Enhanced Alkaline Hydrogen Evolution Reaction

Advanced Functional Materials, EarlyView.
In this study, a novel facet‐junction strategy is proposed to enhance the strong metal‐support interaction (SMSI) between the loaded Ru atoms and the Co3O4 support. The synthesized structure with the incorporation of Ru doping and the (100)/(111) crystal plane junction has a particular influence on the catalyst's hydrogen evolution reaction (HER ...

Ultrasound in the diagnosis and management of pleural effusions [PDF]

, 2015
We review the literature on the use of point-of-care ultrasound to evaluate and manage pleural effusions. Point-of-care ultrasound is more sensitive than physical exam and chest radiography to detect pleural effusions, and avoids many negative aspects of

Robust Systemic and Mucosal Immune Responses to Coxsackievirus B3 Elicited by Spider Silk Protein Based Nanovaccines via Subcutaneous Immunization

Advanced Functional Materials, EarlyView.
Spider minor ampullate silk protein (MiSp) and retinoic acid (RA) based nanovaccine are capable of eliciting both mucosal and systemic immune responses following subcutaneous administration and demonstrate significant protective effects against CVB3 infection in mice.
