Autophagosomes form de novo in a manner that is incompletely understood. Particularly enigmatic are autophagy-related protein 9 (Atg9)-containing vesicles that are required for autophagy machinery assembly but do not supply the bulk of the autophagosomal membrane. In this study, we reconstituted autophagosome nucleation using recombinant components from yeast. We found that Atg9 proteoliposomes first recruited the phosphatidylinositol 3-phosphate kinase complex, followed by Atg21, the Atg2-Atg18 lipid transfer complex, and the E3-like Atg12-Atg5-Atg16 complex, which promoted Atg8 lipidation. Furthermore, we found that Atg2 could transfer lipids for Atg8 lipidation. In selective autophagy, these reactions could potentially be coupled to the cargo via the Atg19-Atg11-Atg9 interactions. We thus propose that Atg9 vesicles form seeds that establish membrane contact sites to initiate lipid transfer from compartments such as the endoplasmic reticulum.Vertebrates vary in their ability to regenerate, and the genetic mechanisms underlying such disparity remain elusive. selleck kinase inhibitor Comparative epigenomic profiling and single-cell sequencing of two related teleost fish uncovered species-specific and evolutionarily conserved genomic responses to regeneration. The conserved response revealed several regeneration-responsive enhancers (RREs), including an element upstream to inhibin beta A (inhba), a known effector of vertebrate regeneration. This element activated expression in regenerating transgenic fish, and its genomic deletion perturbed caudal fin regeneration and abrogated cardiac regeneration altogether. The enhancer is present in mammals, shares functionally essential activator protein 1 (AP-1)-binding motifs, and responds to injury, but it cannot rescue regeneration in fish. This work suggests that changes in AP-1-enriched RREs are likely a crucial source of loss of regenerative capacities in vertebrates.Sleep and wakefulness are homeostatically regulated by a variety of factors, including adenosine. However, how neural activity underlying the sleep-wake cycle controls adenosine release in the brain remains unclear. Using a newly developed genetically encoded adenosine sensor, we found an activity-dependent rapid increase in the concentration of extracellular adenosine in mouse basal forebrain (BF), a critical region controlling sleep and wakefulness. Although the activity of both BF cholinergic and glutamatergic neurons correlated with changes in the concentration of adenosine, optogenetic activation of these neurons at physiological firing frequencies showed that glutamatergic neurons contributed much more to the adenosine increase. Mice with selective ablation of BF glutamatergic neurons exhibited a reduced adenosine increase and impaired sleep homeostasis regulation. Thus, cell type-specific neural activity in the BF dynamically controls sleep homeostasis.Renin-angiotensin system (RAS) is involved in TGF-β-mediated epithelial-to-mesenchymal transition (EMT) and is responsible for airway remodeling in refractory asthma. Obstructive sleep apnea (OSA), which affects RAS activity, is a risk factor for refractory asthma. We aimed to investigate how chronic intermittent hypoxia (IH), the main pathophysiology of OSA, exacerbates asthma and whether Ang-(1-7) protects against chronic IH-induced airway remodeling in asthma. We exposed ovalbumin (OVA)-challenged asthma mice to chronic IH and observed that chronic IH aggravated airway inflammation and collagen deposit in OVA-challenged mice. Compared with the OVA group, the OVA + chronic IH group had a lower expression level of epithelial marker E-cadherin and higher expression levels of mesenchymal markers α-smooth muscle actin and collagen IV in airway epithelia, accompanied with activation of TGF-β/Smad pathway. These changes were reversed by the administration of Ang-(1-7). Consistently, Ang-(1-7) mitigated chronic IH-induced activation of TGF-β-mediated EMT in lipopolysaccharide-treated bronchial epithelial cells in a dose-dependent manner, which was blocked by Ang-(1-7)-specific Mas receptor antagonist A779. Taken together, Ang-(1-7) rescued chronic IH-aggravated TGF-β-mediated EMT to suppress airway remodeling, implying that RAS activity is involved in the mechanisms of OSA-related airway dysfunction in asthma. SIGNIFICANCE STATEMENT OSA is a risk factor for refractory asthma. In this study, we aimed to explore the mechanisms of how OSA exacerbates refractory asthma. We found that chronic IH induces TGF-β-mediated EMT and aggravates airway collagen deposit. We also found that Ang-(1-7) erased the aggravation of TGF-β-mediated EMT and epithelial fibrosis upon chronic IH exposure. These findings provided new insights that the ACE2/Ang-(1-7)/Mas axis might be considered as a potential therapeutic target for patients with asthma and OSA.The pharmacokinetics (PK) of prednisolone (PNL) exhibit nonlinearity related to plasma protein binding, tissue binding, metabolic interconversion with prednisone (PN), and renal elimination. Blood and 11 tissues were collected from male Wistar rats after steady-state (SS) infusion and after subcutaneous boluses of 50 mg/kg of PNL. Concentrations of PNL and PN were measured by liquid chromatography-tandem mass spectrometry. Plasma and tissue profiles were described using a complex physiologically based pharmacokinetics (PBPK) model. Concentrations of PN and PNL were in rapid equilibrium in plasma and tissues. The tissue partition coefficients (K p ) of PNL calculated from most subcutaneously dosed tissue and plasma areas were similar to SS infusion and in silico values. The blood-to-plasma ratio of PNL was 0.71 with similar red blood cell and unbound-plasma concentrations. Plasma protein binding (60%-90%) was related to corticosteroid-binding globulin (CBG) saturation. Tissue distribution was nonlinear. The eqnsights into the pharmacodynamic complexities of corticosteroids. The complex properties of these compounds require innovative PBPK modeling approaches that may be instructive for other therapeutic agents.Associate's Degree in Nursing (ADN) programs rarely offer international service learning experiences. A project involving an ADN program in a southwestern U.S. border city and a care facility in a nearby city in Mexico was initiated to address cultural competence. The purpose of this study was to assess the impact of an international service learning experience on ADN students' cultural competence as measured by pre- and post-scores on the student version of the Inventory for Assessing the Process of Cultural Competence Among Healthcare Professionals-Student Version (IAPCC-SV). Twenty third-semester ADN students participated in a 1-day cross-border international experience. Descriptive statistics provided summaries about the participants and their IAPCC-SV scores. Results indicated a positive effect between participating in an international service learning experience and increased levels of cultural competence. Increasing ADN students' cultural competence through international service learning may help reduce health care disparities among different cultures, promote care that enhances communication between nurses and patients, and build upon therapeutic relationships. International service learning provides ADN students the opportunity to incorporate classroom learning into their care of populations living within diverse communities.
Current research indicates that structured yoga practice may improve physical and emotional symptoms related to cancer treatment. Yoga is recommended for patients with cancer, yet there are barriers to participation in community- and hospital-based classes. Wellness interventions such as yoga are easy to access via the internet, but information can be overwhelming and not tailored to people with cancer.

The purpose of this study was to develop a nurse-led, breast cancer-specific, web-based gentle yoga video for home use, and to understand the feasibility, utilization, and safety of the video in a sample of breast cancer survivors.

Data was collected via open-ended telephone interviews three times over a 4-week period.

The 14 women participating in the study reported that the web-based video was safe in that it resulted in no injury, and was easy to use, and convenient to access. However, most did not continue to practice the video for the full 4 weeks of the study. A knowledge deficit about gentle yoga as a structured mindful movement-based practice rather than a vigorous exercise was identified.

Nurses can provide tailored wellness interventions for cancer survivors via video stream. Future work should include instruction that yoga is a mindfulness-based self-care activity requiring regular practice.

Communication is a key linked to a decrease in medical errors, which compromise patient safety. In response to nursing students' concerns about clinical experiences in which they had witnessed poor communication with the potential to jeopardize patient care, faculty members identified a communication skills training program designed to improve team performance. Senior nursing and social work students at the beginning of their last semester of school were trained in selected modules of the Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) training program and subsequently trained their student colleagues. The goal was to emphasize communication skills and strategies in a sustainable student trainer model. Qualitative and quantitative data about participant experiences revealed significant improvement in teamwork attitudes and communication skills following the training.Visual Thinking Strategies (VTS) is a methodology designed to teach critical thinking, communication, and visual literacy. The Fine Art of Health Care is a VTS-based educational program that brings students from various health-care disciplines to the Lowe Art Museum at the University of Miami in Florida. Twenty-six nurse anesthesia, medical, physical therapy, nursing, and psychology students participated in the workshop during the 2016 fall semester. The students completed an anonymous survey to evaluate their experience. All participants agreed or strongly agreed that VTS helped them understand how to hone their observational and listening skills; 92% agreed that looking at and discussing art has merit with regards to collaborative practice; 96% agreed that VTS helped them improve their communication skills; and 93% found value in the VTS workshop because it provided opportunity to meet and have discussions with students from other disciplines. The arts and humanities have long been recognized as important tools for building multidisciplinary collaboration in health education. There is growing evidence that integrating the arts into the nursing curriculum can have powerful outcomes. These capabilities proved useful in the nurse anesthesia curriculum by allowing skillful conceptualization, and originality and leveling of the playing field for all health-care students.
