The preparation of nanoscale fine bubbles in water is an innovative technology, but no precise method for simultaneously measuring the size and concentration of such bubbles had previously been developed. We have developed a method for simultaneously determining the size and concentration of fine bubbles in water by a light-scattering technique. Dynamic light scattering gives the diffusion constant and particle size of fine bubbles, whereas static light scattering provides their concentration or molar mass...

Breast magnetic resonance imaging (MRI) is the most sensitive imaging modality for the detection of breast cancer, and it is indicated for breast cancer screening in patients at high-risk of developing breast cancer. It is limited to this group given the high cost. In addition, breast MRI is also indicated for evaluating the extent of disease in patients with new breast cancer diagnoses, monitoring the response to neoadjuvant treatment, and evaluating implant integrity. New promising innovations in breast MRI include fast abbreviated MRI, and functional techniques including diffusion-weighted imaging and magnetic resonance spectroscopy are promising particularly as regards to treatment response...

Due to the fast diffusion, small molecules such as hydronium ions (H3O+) are expected to be homogeneously distributed, even close to the site-of-origin. Given the importance of H3O+ in numerous processes, it is surprising that H3O+ concentration ([H3O+]) is yet to be profiled near its generation site with nanometer resolution. Here, we innovated a single-molecule method to probe [H3O+] in nanometer proximity of individual alkaline phosphatases. We designed a mechanophore with cytosine(C)-C mismatch pairs in a DNA hairpin...

Objective: Techniques to validate successful delivery of cell products are expensive, time-consuming, and require transport of the animal to imaging facilities, preventing their widespread use as documentation tools. The goal of this study was to determine if a low-cost portable microscope could provide sufficient performance to be used to document delivery of cell products and track retention over time. Approach: A Dino-Lite fluorescence microscope and an Odyssey CLx whole-animal scanner were compared on the basis of resolution, sensitivity, and linearity...

BACKGROUND: In sub-Saharan Africa, efforts to control antimicrobial resistance (AMR) are aggravated by unregulated drug sales and use, and high connectivity between human, livestock, and wildlife populations. Our previous research indicates that Maasai agropastoralists-who have high exposure to livestock and livestock products and self-administer veterinary antibiotics-harbor antibiotic resistant Escherichia coli (E. coli). Here, we report the results of a public health intervention project among Maasai aimed at reducing selection and transmission of E...

Improving the conductivity and charge transfer kinetics is favourable for innovation of sustainable energy devices such as metal oxide/sulfide-based electrodes. Herein, with an intercalation pseudocapacitance effect, an in situ polymerization-carbonization process for novel carbon-sealed vertical MoS2-SnO2 anchored on graphene aerogel (C@MoS2-SnO2@Gr) has enabled excellent rate performance and durability of the anode of lithium ion batteries to be achieved. The integrated carbon layer and graphene matrix provide a bicontinuous conductive network for efficient electron/ion diffusion pathways...

Many food preparations, pharmaceuticals, and cosmetics use water in oil (W/O) emulsions stabilized by phospholipids. Moreover, recent technological developments try to produce liposomes or lipid coated capsules from W/O emulsions, but are faced with colloidal instabilities. To explore these instability mechanisms, emulsification by sonication was applied in three cycles and the sample stability was studied for 3 hours after each cycle. Clearly identifiable temporal structures of instability provide evidence about the emulsion morphology: an initial regime of about 10 minutes is shown to be governed by coalescence after which Ostwald ripening dominates...

Whole brain tractography using diffusion tensor imaging (DTI) sequences can be used to map cerebral connectivity; however, this can be time-consuming due to the manual component of image manipulation required, calling for the need for a standardized, automated, and accurate fiber tracking protocol with automatic whole brain tractography (AWBT). Interpreting conventional two-dimensional (2D) images, such as computed tomography (CT) and magnetic resonance imaging (MRI), as an intraoperative three-dimensional (3D) environment is a difficult task with recognized inter-operator variability...

Vascular Endothelial Growth Factor Receptor-2 (VEGFR2) is a pro-angiogenic receptor, expressed on endothelial cells (ECs). Although biochemical pathways that follow the VEGFR2 activation are well established, knowledge about the dynamics of receptors on the plasma membrane remains limited. Ligand stimulation induces the polarization of ECs and the relocation of VEGFR2, either in cell protrusions or in the basal aspect in cells plated on ligand-enriched extracellular matrix (ECM). We develop a mathematical model in order to simulate the relocation of VEGFR2 on the cell membrane during the mechanical adhesion of cells onto a ligand-enriched substrate...

The design of new hybrid materials with tailored properties at the nano-, meso- and macro-scale, with the use of structural functional nanobuilding units, is carried out to obtain specific multi-functional materials. Organization into controlled 1D, 2D and 3D architectures with selected functionalities is key for developing advanced catalysts, but this is hardly accomplished using conventional techniques. The use of pre-formed nanostructures, derived either from known materials or made with specific innovative synthetic methodologies, has enormous potential in the generation of multi-site catalytic materials for one-pot processes...

In nursing, the terms "innovation" and "innovative" are used freely, especially when individuals or groups either develop something new or improve upon current practice. Innovation is often considered adjunct work, not part of foundational work that aims to meet the vision, mission, and values of the organization. Nurse leaders must include innovation as an important theme of this foundational work. Innovation must become a core expectation of all nurses and nursing team members. Team members can provide ideas that lead to innovations...

OBJECTIVE It is common for a medical disorder to be managed or researched by individuals who work within different specialties. It is known that both neurosurgeons and neurotologists manage vestibular schwannoma (VS) patients. While overlap in specialty focus has the potential to stimulate multidisciplinary collaboration and innovative thinking, there is a risk of specialties forming closed-communication loops, called knowledge silos, which may inhibit knowledge diffusion. This study quantitatively assessed knowledge sharing between neurosurgery and otolaryngology on the subject of VS...

BACKGROUND: Long-term longitudinal studies with multimodal biomarkers are needed to delve into the knowledge of preclinical AD. Subjective cognitive decline has been proposed as a risk factor for the development of cognitive impairment. Thus, including individuals with SCD in observational studies may be a cost-effective strategy to increase the prevalence of preclinical AD in the sample. OBJECTIVES: To describe the rationale, research protocols and baseline characteristics of participants in the Fundació ACE Healthy Brain Initiative (FACEHBI)...

This work is focused on the development of an innovative multi-analytical methodology to estimate the impact suffered by building materials in coastal environments. With the aim of improving the in situ spectroscopic assessment, which is often based on XRF and Raman spectrometers, diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy was implemented in the diagnosis study. In this way, the additional benefits from DRIFT were compared to the usual in situ analyses of building materials, which often have interferences from fluorescence and reststrahlen effects...
