Interest in Being an Ally Against Violence Toward Women: A Survey of Barbers in Black Communities.

To what extent are barbers willing to act as allies in addressing the abuse of women within Black communities? The study focused on barbers primarily serving Black clients. To gage the cultural viability of utilizing barbershops as intervention sites for intimate partner violence, the authors of this article conducted surveys among barbers in Black communities. The surveys explored the barbers' interest in and capability to act as allies against violence targeting Black women.

Harnessing Plasmonic Interference for Nanoscale Ultrafast Electron Sources.

In this Letter we demonstrate the use of plasmonic focusing in conjunction with nonlinear photoemission to develop geometrically flat nanoscale electron sources with less than 40 pm-rad root mean squared (rms) normalized transverse emittance. Circularly polarized light is incident on a gold Archimedean spiral structure to generate surface-plasmon polaritons that interfere coherently at the center resulting in a 50 nm rms emission area. Such a nanostructured flat surface enables simultaneous spatiotemporal confinement of emitted electrons at the nanometer and femtosecond level and can be used as an advanced electron source for high-repetition-rate ultrafast electron diffraction and microscopy experiments as well as the next generation of miniaturized particle accelerators.

Narratives of Mental Illness and Well-being: A 6-Week Course Aiming to Improve Medical Student Empathy and Resilience Through the Creative Arts.

Objective: Narratives of mental illness and well-being are difficult to communicate in medical education. The arts convey these narratives and may strengthen medical student capabilities.

Methods: This study evaluated the efficacy of a 2021 6-week seminar-style course for medical students focused on five mental states through the lens of visual arts, film, and literature to impact student capabilities.

Associations of discomfort intolerance, discomfort avoidance, and cannabis and alcohol use among persons with chronic pain receiving prescription buprenorphine for opioid use disorder.

Background: Chronic pain and non-prescribed substance use are associated with lower retention in opioid use disorder (OUD) treatment. We examined the associations of perceived capacity to tolerate uncomfortable physical sensations (discomfort intolerance and discomfort avoidance) and cannabis and alcohol use among persons with chronic pain receiving prescription buprenorphine for OUD.

Methods: This study utilizes baseline data from 163 persons with chronic pain receiving prescription buprenorphine for OUD enrolled in the Treating Opioid use, Persistent Pain, and Sadness (TOPPS) intervention trial.

CandyCollect: An Open-Microfluidic Device for the Direct Capture and Enumeration of Salivary-Extracellular Vesicles.

Extracellular Vesicles (EVs) are membrane-derived vesicles shed by cells into the extracellular space that play key roles in intercellular communication and other biological processes. As membrane-bound cargos of nucleic acids and other proteins that are abundantly found in virtually every biofluid including blood, urine, and saliva, EVs are widely regarded as promising biomarkers for disease detection. While it is an increasingly promising biofluid from which to isolate EVs, saliva poses challenges due its complexity and heterogeneity-cells, debris, and other proteins can inhibit the isolation of EVs by traditional platforms.
