Splenic fibroblasts control marginal zone B cell movement and function via two distinct Notch2-dependent regulatory programs.

Innate-like splenic marginal zone (MZ) B (MZB) cells play unique roles in immunity due to their rapid responsiveness to blood-borne microbes. How MZB cells integrate cell-extrinsic and -intrinsic processes to achieve accelerated responsiveness is unclear. We found that Delta-like1 (Dll1) Notch ligands in splenic fibroblasts regulated MZB cell pool size, migration, and function.

A three-terminal memristor with an ultrasmall footprint of only 0.07 μm and critical dimensions of 70 nm × 10 nm × 6 nm is introduced. The device's feature is the presence of a gate contact, which enables two operation modes: either tuning the set voltage or directly inducing a resistance change.

Measuring dielectric and electro-optic responses of thin films using plasmonic devices.

This paper introduces a simple method for the measurement of the relative permittivity and the Pockels coefficient of electro-optic (EO) materials in a waveguide up to sub-THz frequencies. By miniaturizing the device and making use of plasmonics, the complexities of traditional methods are mitigated. This work elaborates the fabrication tolerance and simplicity of the method, and highlights its applicability to various materials, substrates and configurations.

C- and O-Band Dual-Polarization Fiber-to-Chip Grating Couplers for Silicon Nitride Photonics.

Highly efficient coupling of light from an optical fiber to silicon nitride (SiN) photonic integrated circuits (PICs) is experimentally demonstrated with simple and fabrication-tolerant grating couplers (GC). Fully etched amorphous silicon gratings are formed on top of foundry-produced SiN PICs in a back-end-of-the-line (BEOL) process, which is compatible with 248 nm deep UV lithography. Metallic back reflectors are introduced to enhance the coupling efficiency (CE) from -1.

Patient and Provider Perspectives on Processes of Engagement in Outpatient Treatment for Opioid Use Disorder: A Scoping Review.

Effective treatment for opioid use disorder (OUD) is available, but patient engagement is central to achieving care outcomes. We conducted a scoping review to describe patient and provider-reported strategies that may contribute to patient engagement in outpatient OUD care delivery. We searched PubMed and Scopus for articles reporting patient and/or provider experiences with outpatient OUD care delivery.

Exploring Professional Anticipatory Socialization: Who Are the Messengers Influencing Future Physicians' Perceptions of Advanced Practice Providers?

Purpose: Evidence exists that physicians in training and practice often do not understand advanced practice providers (APPs) and their roles in professional practice. This study asked the question: What are the messages and messengers during the anticipatory professional socialization period that potentially influence how residents perceive APPs?

Methods: Semistructured interviews were conducted with 15 residents in one academic setting. Transcripts were analyzed using an inductive approach to coding to identify the messages and sources of those messages (messengers) that had influenced how residents perceived APPs.

Notch signaling drives intestinal graft-versus-host disease in mice and nonhuman primates.

Notch signaling promotes T cell pathogenicity and graft-versus-host disease (GVHD) after allogeneic hematopoietic cell transplantation (allo-HCT) in mice, with a dominant role for the Delta-like Notch ligand DLL4. To assess whether Notch's effects are evolutionarily conserved and to identify the mechanisms of Notch signaling inhibition, we studied antibody-mediated DLL4 blockade in a nonhuman primate (NHP) model similar to human allo-HCT. Short-term DLL4 blockade improved posttransplant survival with durable protection from gastrointestinal GVHD in particular.

[Ophthalmic findings caused by Encephalitozoon cuniculi (strain III) in a dog].

A 2-year-old female mixed-breed canine patient from Namibia presented originally with chronic uveitis. A serum antibody titer and a PCR test performed on the aqueous humor were positive for encephalitozoon cuniculi. The left eye showed an immature anterior focal cortical cataract in the periphery with suspected lens capsule rupture and signs of chronic uveitis.

A Reinvestigation of the Role of the Sorbic Acid Tail on the Antibacterial and Anti-Tuberculosis Properties of Moiramide B.

Due to worldwide increasing resistances, there is a considerable need for antibacterial compounds with modes of action not yet realized in commercial antibiotics. One such promising structure is the acetyl-CoA carboxylase (ACC) inhibitor moiramide B which shows strong antibacterial activity against gram-positive bacteria such as Bacillus subtilis and weaker activities against gram-negative bacteria. However, the narrow structure-activity relationship of the pseudopeptide unit of moiramide B represents a formidable challenge for any optimization strategy.

Implementing complex interventions to mitigate burnout among qualified healthcare professionals: a realist review protocol.

Introduction: Reported burnout rates among qualified healthcare professionals (QHP) are alarming. Systematic reviews evaluating the effectiveness of burnout interventions for QHP exist; however, findings are contradictory. In addition, to date, there is no indication of how these interventions work and what specific intervention elements mitigate burnout.

The "therapeutic relationship:" emergence, eclipse, and transformations of a social technology.

This essay situates the history of "the relationship" as a therapeutic technology within the broader context of changing social relations in the twentieth-century United States. More specifically, it outlines the emergence and subsequent diffusion of practices that aim to cultivate a social bond between therapist and patient that may serve as a psychotherapeutic tool. The article highlights the transformations of this technology as its institutional and epistemic foundations became challenged.

"Heroin Mothers," "Methadone Babies," and the Medical Controversy over Methadone Maintenance in the Early 1970s.

This article situates the emergence of sensationalized news reports of "infant addicts" and the concurrently evolving study of neonatal drug withdrawal within the context of the expansion of methadone maintenance treatment (MMT) in the United States. It details how, in the early 1970s, concerns about pregnant narcotic addicts and their infants became part of the politically charged debate over methadone maintenance. The popular press amplified the apprehensions of a vocal group of pediatricians who saw in infants' withdrawal an indication of methadone's inherent harmfulness and potential toxicity.

Which learning experiences support an interprofessional identity? A scoping review.

In recent years, health professions researchers have suggested that a dual identity that includes both a professional and interprofessional identity is essential to interprofessionality. This scoping review sought to describe the learning experiences that may support the development of an interprofessional identity, providing direction for future research. A scoping review was conducted to identify papers published between 2000 and 2020 that provided empiric evidence to support the impact of planned or spontaneous learning experiences involving two or more healthcare professions that fostered the development of an "interprofessional identity," or a sense of belonging to an interprofessional community.

Absence of the Fragile X messenger ribonucleoprotein alters response patterns to sounds in the auditory midbrain.

Among the different autism spectrum disorders, Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability. Sensory and especially auditory hypersensitivity is a key symptom in patients, which is well mimicked in the mouse model. However, the physiological mechanisms underlying FXS's acoustic hypersensitivity in particular remain poorly understood.
