Significance: Conventional ultrasound-guided vascular access procedures are challenging due to the need for anatomical understanding, precise needle manipulation, and hand-eye coordination. Recently, augmented reality (AR)-based guidance has emerged as an aid to improve procedural efficiency and potential outcomes. However, its application in pediatric vascular access has not been comprehensively evaluated.

Background: Current methods of burn estimation can lead to incorrect estimates of the total body surface area (TBSA) burned, especially among injured children. Inaccurate estimation of burn size can impact initial management, including unnecessary transfer to burn centres and fluid overload during resuscitation. To address these challenges, we developed a smartphone application (EasyTBSA) that calculates the TBSA of a burn using a body-part by body-part approach.

This report describes the development of a photochemical method for C(sp )-H pyridination that leverages the photoexcitation of electron donor-acceptor (EDA) complexes. Experimental and DFT studies show that black light (λ ≈350 nm) irradiation of solutions of protonated pyridines (acceptors) and aromatic C-H substrates (donors) results in single electron transfer to form aryl radical cation intermediates that can be trapped with pyridine nucleophiles under aerobic conditions. With some modification of the reaction conditions, this EDA activation mode is also effective for promoting the oxidatively triggered S Ar pyridination of aryl halides.

Article Synopsis
  • - Ocean acidification negatively impacts the exoskeleton of southern Tanner crabs, specifically affecting their ability to maintain hard, mineralized structures due to lower pH levels during prolonged exposure.
  • - Crabs at a pH of 7.5 showed a 38% reduction in claw microhardness and exhibited structural damage, including thinning and erosion of both claws and carapace, compared to those at pH 8.1.
  • - Chemical analysis revealed changes in the elemental content of the carapace, with reduced calcium and increased magnesium at lower pH, and a phase shift in calcium carbonate that suggests a transition from amorphous forms to more stable calcite at higher pH levels.

The popularity of cell-laden injectable hydrogels has steeply increased due to their compatibility with minimally invasive surgical procedures. However, the diffusion of indispensable molecules for cell survival through bulk hydrogel structures, particularly oxygen, is often limited to micrometric distances, often hampering cell viability or uniform tissue formation in constructs with clinically relevant sizes. The introduction of micropores in hydrogels or the use of oxygen-generating materials has enabled combining advantages of porous 3D scaffolds with the injectability properties of in situ-solidifying hydrogels.

Technological advances in game-mediated robotics provide an opportunity to engage children with cerebral palsy (CP) and other neuromotor disabilities in more frequent and intensive therapy by making personalized, programmed interventions available 24/7 in children's homes. Though shown to be clinically effective and feasible to produce, little is known of the subjective factors impacting acceptance of what we term assistive/rehabilitative (A/R) gamebots by their target populations. This research describes the conceptualization phase of an effort to develop a valid and reliable instrument to guide the design of A/R gamebots.

Therapeutic ultrasound presents a potential novel treatment for type 2 diabetes mellitus that utilizes the non-invasive application of ultrasound energy to treat secretory defects in the earlier stages of the disease. Our previous studies have shown that ultrasound is capable of stimulating insulin release from pancreatic beta cells, safely and effectively. This study aims to both examine the calcium-dependent mechanisms of ultrasound-mediated insulin release from pancreatic beta cells using three complementary modalities - carbon fiber amperometry, ELISA studies, and Ca2+ fluorescence imaging - and to study the translational potential of therapeutic ultrasound using transgenic hyperglycemic mice for safety and efficacy studies.
