876, 0.869 and 0.869, respectively upon test images. With an overall F1-score of 0.870, our ensemble-based approach outperforms previous approaches with single fine-tuned CNN, CNN trained from scratch, and traditional machine learning by 0.019, 0.064 and 0.183, respectively. Ensemble approach can perform better than individual classifier-based ones, provided the constituent classifiers are chosen wisely. The empirical choice of classifiers reinforces the intuition that models which are newer and outperformed in their native domain are more likely to outperform in transferred-domain, since the best ensemble dominantly consists of more lately proposed and better architectures.Under physiological conditions, Bacillus fastidious uricase (BFU) activity shows negligible lagging phase before the exponential decrease; mutants are thus designed for long lagging phases before exponential activity decreases. On homodimer surface of BFU (4R8X.pdb), the last fragment ANSEYVAL at the C-terminus forms a loop whose Y319 is H-bonded by the buried D257 in the same monomer. Within 1.5 nm from the α-carboxyl group of the last leucine (L322), E30, K26, D257, R258, E311, K312 and E318 from the same monomer plus D126 and K127 from a monomer of the other homodimer generate an electrostatic interaction network. Within 1.5 nm from Y319, D307 and R310 in the same monomer interact with ionized residues around the inter-chain β-sheet in the same homodimer. Mutagenesis of Y319R is designed to strengthen the original interactions and concomitantly generate new electrostatic attractions between homodimers. Under physiological conditions, the mutant V144A/Y319R showed an approximately 4 week lagging phase before the exponential activity decrease, an apparent half-life of activity nearly three folds of mutant V144A, but comparable activity. The introduction of ionizable residues into the C-terminus contacting the other homodimer for additional and/or stronger electrostatic attractions between homodimers may be a universal approach to thermostable mutants of uricases.Sepsis-induced lung injury was the most common cause of death in patients. This study aimed to investigate whether PD-L1 regulates the inflammation in LPS-induced lung epithelial cells and vascular endothelial cells by interacting with the HIF-1α signaling pathway. Sepsis-induced lung injury mice were constructed by cecal ligation and puncture (CLP) procedure, and lipopolysaccharide (LPS)-induced lung epithelial cells and vascular endothelial cells simulate the sepsis-induced lung injury model in vitro. Hematoxylin-eosin (HE) staining detected the morphological changes of the lung tissues, and immunohistochemistry (IHC) detected the PD-L1 expression in lung tissues. Bicinchoninic acid (BCA) assay determined the protein concentration in bronchial alveolar lavage fluid (BALF). The number of PD-1 (+) cells in blood was detected by flow cytometry. The apoptosis in lung tissues and LPS-induced cells was analyzed by TUNEL assay. The inflammatory factor levels and HIF-1α in lung tissues and LPS-induced cells were anion of HIF-1α and related pathways. In conclusion, downregulation of PD-L1 alleviated the inflammation in LPS-induced lung epithelial cells and vascular endothelial cells by suppressing the HIF-1α signaling pathway.Evidence-based and culturally relevant parenting programs strengthen adults' capacity to support children's health and development. Optimizing parent participation in programs implemented at scale is a prevailing challenge. Our collaborative team of program developers, implementers, and researchers applied insights from the field of behavioral economics (BE) to support parent participation in ParentCorps-a family-centered program delivered as an enhancement to pre-kindergarten-as it scaled in a large urban school district. We designed a bundle of BE-infused parent outreach materials and successfully showed their feasibility in site-level randomized pilot implementation. The site-le
