Flexible and stretchable strain sensors are in high demand in sports performance monitoring, structural health monitoring, and biomedical applications. However, existing stretchable soft sensors, primarily based on soft polymer materials, often suffer from drawbacks, including high hysteresis, low durability, and delayed response. To overcome these limitations, we introduced a stretchable miniature fiber sensor comprised of a stretchable core tightly coiled with parallel conductive wires.

While some materials can be discovered and engineered using standalone self-driving workflows, coordinating multiple stakeholders and workflows toward a common goal could advance autonomous experimentation (AE) for accelerated materials discovery (AMD). Here, we describe a scalable AMD paradigm based on AE and "collaborative learning". Collaborative learning using a novel consensus Bayesian optimization (BO) model enabled the rapid discovery of mechanically optimized composite polysaccharide hydrogels.

Background: Trans-Atlantic collaboration between nursing and pharmacy programs for interprofessional education (IPE) is uncommon. A literature search revealed limited sources for comparison, leading to the creation of a stakeholder committee from four colleges: Augusta University College of Nursing and University of Georgia College of Pharmacy, representing the United States of America, and Robert Gordon University Schools of Nursing and Midwifery and Pharmacy and Life Sciences, representing Scotland. A proposal outlining an international IPE experience designed to prepare future healthcare professionals to collaboratively address the challenges facing rural and underserved populations by supporting improvements in access to care for both countries.

Glioblastoma (GBM) is the most common and malignant type of primary brain tumor. Even after surgery and chemoradiotherapy, residual GBM cells can infiltrate the healthy brain parenchyma to form secondary tumors. To mitigate GBM recurrence, we recently developed an injectable hydrogel that can be crosslinked in the resection cavity to attract, collect, and ablate residual GBM cells.

Background: Community pharmacists improve health, reduce fragmentation in care, lower health costs, and improve health outcomes. In Georgia, pharmacists are able to enter collaborative drug therapy management protocols, such as hypertension management, with a collaborating physician, which may allow pharmacists to provide advanced community pharmacy services (ACPS), however few Georgia pharmacists have this licensure. No program(s) exist that empower pharmacists to successfully engage in ACPS across the state of Georgia nor trains pharmacists to successfully engage in collaborative practice.

Distractor suppression allows us to remain on-task in the presence of distractions by filtering task-irrelevant information from ongoing cognitive processing and responding. Electrophysiological studies have revealed that this key feature of selective attention is a dynamic process that involves at least two distinct stages of processing. Two important aspects of these processing stages remain unclear: Whether the processing of emotional distractors at an earlier stage is automatic, as reflected in the N2/early posterior negativity (EPN) component; and what functional-anatomical brain systems are recruited in each stage.

Aneuploidy is nearly ubiquitous in tumor genomes, but the role of aneuploidy in the early stages of cancer evolution remains unclear. Here, by inducing heterogeneous aneuploidy in non-transformed human colon organoids (colonoids), we investigated how the effects of aneuploidy on cell growth and differentiation may promote malignant transformation. Previous work implicated p53 activation as a downstream response to aneuploidy induction.

Introduction: Hypertension, the clinical condition of persistent high blood pressure (BP), is preventable yet remains a significant contributor to poor cardiovascular outcomes. Digital self-management support tools can increase patient self-care behaviours to improve BP. We created a patient-facing and provider-facing clinical decision support (CDS) application, called the Collaboration Oriented Approach to Controlling High BP (COACH), to integrate home BP data, guideline recommendations and patient-centred goals with primary care workflows.

Objective: This study used a self-authorship framework to explore if diversity, equity, and inclusion (DEI) and social determinants of health (SDoH)-focused laboratories and learning activities increase student confidence in understanding aspects of implicit bias and SDoH, and how these activities impact student comfort in discussing and confidence in initiating conversations on DEI/SDoH topics with colleagues, faculty, supervisors, and patients.

Methods: First-year PharmD students engaged in 3 learning activities across 2 courses. Students were challenged to evaluate their biases and incorporate DEI/SDoH into their professional identity formation.

HSV infects keratinocytes in the epidermis of skin via nectin-1. We established a human foreskin explant infection model to investigate HSV entry and spread. HSV1 entry could only be achieved by the topical application of virus via high density microarray projections (HD-MAPs) to the epidermis, which penetrated beyond one third of its thickness, simulating in vivo microtrauma.

Polysaccharide-based hydrogels are promising for many biomedical applications including drug delivery, wound healing, and tissue engineering. We illustrate herein self-healing, injectable, fast-gelling hydrogels prepared from multi-reducing end polysaccharides, recently introduced by the Edgar group. Simple condensation of reducing ends from multi-reducing end alginate (M-Alg) with amines from polyethylene imine (PEI) in water affords a dynamic, hydrophilic polysaccharide network.

Introduction: Articulography and functional neuroimaging are two major tools for studying the neurobiology of speech production. Until now, however, it has generally not been feasible to use both in the same experimental setup because of technical incompatibilities between the two methodologies.

Methods: Here we describe results from a novel articulography system dubbed Magneto-articulography for the Assessment of Speech Kinematics (MASK), which is technically compatible with magnetoencephalography (MEG) brain scanning systems.

Background: Despite accounting for more than half of new Human Immunodeficiency Virus diagnoses in the United States, the South has fewer than 30% of all pre-exposure prophylaxis users. Pre-exposure prophylaxis access geospatial analyses have focused on drive time but analyses along public transit routes have not been evaluated. Given the proximity to pharmacists and pharmacies, involvement in pre-exposure prophylaxis services may increase access and uptake of this preventative health need.

Article Synopsis
  • Inflammation-associated fibroblasts (IAFs) play a crucial role in the progression and drug resistance of chronic inflammatory diseases like inflammatory bowel disease (IBD) by affecting epithelial cells, although their specific impact was previously unclear.
  • By creating an in vitro model with human colon fibroblasts stimulated by cytokines, researchers found that when these fibroblasts were cocultured with patient-derived colon organoids (colonoids), they caused rapid growth and damaging effects on the epithelial cells.
  • The study identified a mechanism involving prostaglandin E and its receptor EP4 that mediated the damaging effects of IAFs, suggesting that targeting this pathway with specific inhibitors could help restore normal function and stability in epithelial cells affected by inflammation.
