question:
Context: We hypothesized that self-reported pad use per day (PPD) after pubovaginal sling (PVS) correlated with postoperative quality of life (QOL) scores.', 'Two hundred fifteen women completed the incontinence impact questionnaire 7 (IIQ-7) and urogenital distress inventory 6 (UDI-6) before PVS and during follow-up. Starting 3 days before a visit, women recorded the number of protective urinary pad changes per day. Analysis of variance and Pearson correlation tests were used to determine if women reporting zero, one, or greater than or equal to two urinary pads per day after PVS had significantly different changes in baseline QOL scores.', 'Over a mean 8.5 months follow-up after PVS, 131, 56, and 28 women reported zero, one, and greater than or equal to two pad changes/day. Each pad group showed progressively less improvement from baseline IIQ-7 and UDI-6 scores after PVS. Change in IIQ-7 and UDI-6 scores negatively correlated with PPD (p < 0.0001).
Answer: Self-reported PPD after PVS reflects patient perception of urinary-specific QOL.
answer:
Does self-reported pad use per day reflect patient quality of life after pubovaginal sling surgery?


question:
Context: Diabetic cardiomyopathy (DCM) is associated with suppressed autophagy and augmented apoptosis in the heart although the interplay between the two remains elusive. The ability of mammalian sterile 20-like kinase 1 to regulate both autophagy and apoptosis prompted us to investigate it as a possible candidate in the progression of DCM.', 'Wild-type, Mst1 (also known as Stk4) transgenic and Mst1-knockout mice were challenged with streptozotocin to induce experimental diabetes. In addition, cultured neonatal mouse cardiomyocytes were subjected to simulated diabetes to probe mechanisms.', 'Mst1 knockout alleviated while Mst1 overexpression aggravated cardiac dysfunction in diabetes. Diabetic Mst1 transgenic mice exhibited decreased LC3 expression and enhanced protein aggregation. In contrast, typical autophagosomes were observed in diabetic Mst1-knockout mice with increased LC3 expression and reduced protein aggregation. Mst1 downregulation promoted autophagic flux as demonstrated by increased LC3-II and decreased p62 expression in the presence of bafilomycin A1. Furthermore, Mst1 overexpression increased, while Mst1 knockout decreased, cardiomyocyte apoptosis both in vivo and in vitro. Co-immunoprecipitation assays showed that Mst1 overexpression promoted Beclin1 binding to B cell lymphoma 2 (Bcl-2) and induced dissociation of Bcl-2 from Bax in diabetic mice. Conversely, Mst1 knockout disrupted the Beclin1-Bcl-2 complex and enhanced the interaction between Bcl-2 and Bax.
Answer: Mst1 knockout restores autophagy and protects against apoptosis in cardiomyocytes, en route to the rescue against DCM.
answer:
Does mST1 coordinately regulate autophagy and apoptosis in diabetic cardiomyopathy in mice?


question:
Context: Lung morphogenesis is regulated by interactions between the canonical Wnt/β-catenin and Kras/ERK/Foxm1 signaling pathways that establish proximal-peripheral patterning of lung tubules. How these interactions influence the development of respiratory epithelial progenitors to acquire airway as compared to alveolar epithelial cell fate is unknown. During branching morphogenesis, SOX9 transcription factor is normally restricted from conducting airway epithelial cells and is highly expressed in peripheral, acinar progenitor cells that serve as precursors of alveolar type 2 (AT2) and AT1 cells as the lung matures.', 'To identify signaling pathways that determine proximal-peripheral cell fate decisions, we used the SFTPC gene promoter to delete or overexpress key members of Wnt/β-catenin and Kras/ERK/Foxm1 pathways in fetal respiratory epithelial progenitor cells. Activation of β-catenin enhanced SOX9 expression in peripheral epithelial progenitors, whereas deletion of β-catenin inhibited SOX9. Surprisingly, deletion of β-catenin caused accumulation of atypical SOX9-positive basal cells in conducting airways. Inhibition of Wnt/β-catenin signaling by Kras(G12D) or its downstream target Foxm1 stimulated SOX9 expression in basal cells. Genetic inactivation of Foxm1 from Kras(G12D) -expressing epithelial cells prevented the accumulation of SOX9-positive basal cells in developing airways.
Answer: Interactions between the Wnt/β-catenin and the Kras/ERK/Foxm1 pathways are essential to restrict SOX9 expression in basal cells. Developmental Dynamics 245:590-604, 2016. © 2016 Wiley Periodicals, Inc.
answer:

Are β-catenin and Kras/Foxm1 signaling pathway critical to restrict Sox9 in basal cells during pulmonary branching morphogenesis?
