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.

Global distribution and gap analysis of equine housing research: The findings so far and where to go next.

As a free-ranging, social species, the housing of horses () may limit their opportunity to display natural behaviour, compromising well-being. This review records and presents studies that have investigated horse housing design, evaluates the location and number of studies carried out to date, and reports the methods used to assess impact on equine well-being. A Boolean search was conducted in two databases: Web of Science and Scopus, filtered according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) protocol, resulting in 60 peer-reviewed papers for evaluation.

Hyperpolarised [2-C]-pyruvate by C SABRE in an acetone/water mixture.

Signal Amplification By Reversible Exchange (SABRE) can provide strong signal enhancement (SE) to an array of molecules through reversible exchange of parahydrogen (pH) derived hydrides and a suitable substrate coordinated to a transition metal. Among the substrates that can be used as a probe for hyperpolarised NMR and MRI, pyruvate has gained much attention. SABRE can hyperpolarise pyruvate in a low cost, fast, and reversible fashion that does not involve technologically demanding equipment.

A qualitative account of mothers of pediatric heart transplant recipients' experience at a pilot mindfulness-based retreat: insights for implementation.

Objective: To explore participants' shared experience attending a pilot mindfulness-based retreat (MBR) intervention supporting the psychological well-being of mothers of pediatric heart transplant (HTx) recipients.

Methods: A qualitative description approach was used within a larger hybrid mixed-methods pilot study evaluating the implementation-effectiveness of a 2-day MBR tailored specifically for a pediatric HTx population. A purposive sample of mothers was recruited from a leading Canadian pediatric HTx center, and each represented a primary, female-identifying caregiver, sharing residence with a pediatric HTx recipient of at least 4 months post-transplant.
