Boron nitride quantum dots (BNQDs) have been proposed as probes for bioimaging owing their to outstanding photoluminescent properties, although their hydrophobic nature and strong aggregation tendency in aqueous media limit their application in the biomedical field. In this work, we synthesize BNQDs by a liquid exfoliation–solvothermal process under pressure from boron nitride nanoparticles in N,N-dimethylformamide. The BNQDs display an average size of 3.3 ± 0.6 nm, as measured by transmission electron microscopy, and a (100) crystalline structure. In addition, a quantum yield of 21.75 ± 0.20% was achieved. To ensure complete dispersibility in water and prevent possible elimination by renal filtration upon injection, the BNQDs (20% w/w) are encapsulated within poly(ethylene glycol)-b-poly(epsilon-caprolactone) nanoparticles by a simple and scalable nanoprecipitation method, and hybrid nanocomposite particles with significantly stronger photoluminescence than their free counterparts are produced. Finally, their optimal cell compatibility and bioimaging features are demonstrated in vitro in murine macrophage and human rhabdomyosarcoma cell lines. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Hypertension is among the most commonly managed diseases in general practice. Therapeutic inertia could be responsible for the vast majority of cardiovascular events in patients with hypertension. The present study was conducted to explore views and opinions of clinicians involved in providing health care services to patients with hypertension in Palestine and achieve formal consensus on promoters of the phenomenon of therapeutic inertia from their point of view. STUDY DESIGN: In this exploratory study, a mixed-methods approach combining literature search, qualitative interviews, and 2 Delphi technique rounds was used. METHODS: Interviews with key contact clinicians (n = 18) were conducted. To achieve formal consensus on promoters of therapeutic inertia in hypertension, 2 Delphi rounds were conducted using a panel of general practitioners, family medicine specialists, and internal medicine specialists (n = 50). RESULTS: The majority of the panel members (90%) agreed that therapeutic inertia was prevalent in treating patients with hypertension in Palestine. Of the 41 potential promoters, consensus was achieved on 37 (90.2%). Of these 37 promoters, 21 (56.8%) were clinician-related, 10 (27.0%) were patient-related, and 6 (16.2%) were health care system--related factors. The study explored views and opinions of clinicians involved in providing health care services to patients with hypertension in Palestine relevant to therapeutic inertia in hypertension. CONCLUSIONS: Findings of this study could inform policy and decision makers to devise strategies to eliminate or reduce therapeutic inertia in managing hypertension in Palestinian clinical practice. Future studies are needed to determine whether such strategies can improve outcomes of patients with hypertension. [ABSTRACT FROM AUTHOR]
