Nursing teams were invited to participate and complete the program with the implementation of EBP projects over the following year.

Participants' EBP knowledge, skills, competencies, and beliefs were significantly improved and sustained over 12months.

A team-based EBP skill-building program was an effective strategy for building EBP competence, practice, and culture. This initiative demonstrated that the direct involvement of leadership and infrastructure to support EBP were crucial factors for building and sustaining an EBP culture.

Despite recent advances in intensive care medicine, the mortality is still as high as 50%, which stems from our insufficient understanding of the underlying mechanisms of the diseases. The roles of C/EBPβ and C/EBPδ have been extensively investigated in LPS- and IgG immune complexes-stimulated acute lung injury. However, the effect of C/EBPγ, belonging to the same family as C/EBPβ and C/EBPδ, on ALI has not been elucidated. Our previous data have shown that during LPS-/IgG immune complexes-induced ALI, the DNA binding activities of C/EBPγ are obviously reduced. In the present study, we determine whether ALI induced by LPS and IgG immune complexes is affected by C/EBPγ. We find that adenovirus-mediated C/EBPγ expression in the lung tissue alleviates LPS-/IgG immune complexes-stimulated acute pulmonary damage through reducing vascular permeability changes and recruitment of neutrophils into alveolar spaces, which might be linked to a decrease in the production of pro-inflammatory mediators, such as TNF-α and IL-6. Moreover, our data obtained from macrophages in vitro are consistent with the in vivo results. In terms of mechanisms, C/EBPγ might inhibit LPS-/IgG immune complexes-mediated inflammation via alleviating C/EBPβ and C/EBPδ transcription activities as reflected by luciferase assays. However, the NF-κB-dependent production of pro-inflammatory mediators is not affected by C/EBPγ. Taken together, C/EBPγ suppresses LPS- and IgG immune complexes-induced pro-inflammatory mediators' production through the downregulation of C/EBP but not NF-κB activation, leading to the subsequent attenuation of ALI. Collectively, our data provide an insight into the critical role of C/EBPγ in acute lung injury.

Lesion size and continuity in dragging laser balloon (LB) ablation, which may enable fast and durable pulmonary vein isolation for atrial fibrillation, are unknown. We evaluated the differences in size and continuity of linear lesions formed by dragging ablation and conventional point-by-point ablation using an LB in vitro model.

Chicken muscles were cauterized using the first-generation LB in dragging and point-by-point fashion. Dragging ablation was manually performed with different dragging speeds (0.5-2°/s) using an overlap ratio of the beginning and last site during one application at 12 W/20 s and 8.5 W/30 s. Point-by-point ablation was performed with 25% and 50% overlap ratios at six energy settings (5.5 W/30 s to 12 W/20 s). Lesion depth, width, and continuity were compared. learn more Lesion continuity was assessed by the surface and deep visible gap degree categorized from 1 (perfect) to 3 (poor). Twenty lesions were evaluated for each ablation protocol. Lesion depth and width in dragging ablation at high power (12 W) were comparable with most measurements in point-by-point ablation. Lesion depth and width were smaller at faster-dragging speed and lower power (8.5 W) in dragging ablation. The surface visible gap degree was better in dragging ablation at all dragging speeds than a 25% overlapped point-by-point ablation (p < .001).

Dragging LB ablation at high power provides deep and continuous linear lesion formation comparable with that of point-by-point LB ablation. However, lesion depth and width depending on the dragging speed and power.

However, a chain-walking protocol for nonconjugated dienes remains scarcely reported, and developments are currently ongoing. In this Communication, a nickel-catalyzed asymmetric hydrocyanation of nonconjugated dienes involving a chain-walking process is demonstrated. The reaction exhibits excellent regio- and chemoselectivity, and a wide range of substrates were tolerated, delivering the products in high yields and enantioselectivities. Deuterium-labeling experiments support the chain-walking process, which involves an iterative β-H elimination and reinsertion processes. Gram-scale synthesis, regioconvergent experiments, and downstream transformations gave further insights into the high potential of this transformation.The endosomal sorting complex required for transport (ESCRT) machinery is an ancient, evolutionarily conserved membrane remodeling complex that is essential for multivesicular body (MVB) biogenesis in eukaryotes. FYVE DOMAIN PROTEIN REQUIRED FOR ENDOSOMAL SORTING 1 (FREE1), which was previously identified as a plant-specific ESCRT component, modulates MVB-mediated endosomal sorting and autophagic degradation. Although the basic cellular functions of FREE1 as an ESCRT component have been described, the regulators that control FREE1 turnover remain unknown. Here, we analyzed how FREE1 homeostasis is mediated by the RING-finger E3 ubiquitin ligases, SINA of Arabidopsis thaliana (SINATs), in response to iron deficiency. Under iron-deficient growth conditions, SINAT1-4 were induced and ubiquitinated FREE1, thereby promoting its degradation and relieving the repressive effect of FREE1 on iron absorption. By contrast, SINAT5, another SINAT member that lacks ubiquitin ligase activity due to the absence of the RING domain, functions as a protector protein which stabilizes FREE1.
