    A majority of the studies provided links between varying social capital indicators and a range of mental health outcomes (70%), however such evidence was associational. Only few studies inferred the causal direction between social capital and health (10%) and there were no dedicated studies on measurement. find more Findings suggest that literature on social capital and young people’s mental health has grown but continues to be variously described and measured. It requires better utilization of existing knowledge and new research to improve its application in practice.A complexity-informed approach has recently been proposed as a hopeful revolution for health promotion (HP), requesting appropriate ways of tackling the complexities of health, equity and well-being. In addition, co-creation has gained traction as an approach to tackle complexity. HP and co-creation are established concepts that have long been enacted in practice. Although each concept is premised on similar approaches to value-creation such as participation and collaboration, little has been done to link the two approaches. To advance complexity-informed HP, this scoping review presents findings from peer-reviewed articles, published in English, between 2009 and March 2020. Articles were identified through searches of academic databases. Twenty-seven articles met the inclusion criteria, explicitly linking HP and co-creation. Included articles were charted by descriptive information and main focus, and advanced by a thematic analysis. Four themes suggest a potential avenue for advancing complexity-informed HP (i) dealing with complexity, (ii) value creation, (iii) the value of the values and (iv) benefits and challenges. While current links between HP and co-creation are scarce they are increasing and promising. Based on the findings from the review, propositions to advance complexity-informed HP is outlined and discussed. Overall it is argued that co-creation and HP are mutually beneficial concepts, providing a framework for participative, collaborative, context-sensitive and knowledge-based practice that reflects the complex nature of health. More research is needed to highlight potential and challenges of integrating co-creation in HP, especially related to health equity and sustainable development.The CRISPR-Cas system provides adaptive immunity for bacteria and archaea to combat invading phages and plasmids. Phages evolved anti-CRISPR (Acr) proteins to neutralize the host CRISPR-Cas immune system as a counter-defense mechanism. AcrIF7 in Pseudomonas aeruginosa prophages strongly inhibits the type I-F CRISPR-Cas system. Here, we determined the solution structure of AcrIF7 and identified its target, Cas8f of the Csy complex. AcrIF7 adopts a novel β1β2α1α2β3 fold and interacts with the target DNA binding site of Cas8f. Notably, AcrIF7 competes with AcrIF2 for the same binding interface on Cas8f without common structural motifs. AcrIF7 binding to Cas8f is driven mainly by electrostatic interactions that require position-specific surface charges. Our findings suggest that Acrs of divergent origin may have acquired specificity to a common target through convergent evolution of their surface charge configurations.Differentiation of pluripotent stem cells into functional parathyroid-like cells would accelerate development of important therapeutic options for subjects with parathyroid-related disorders, from the design and screening of novel pharmaceutical agents to the development of durable cellular therapies. We have established a highly reproducible directed differentiation approach leading to PTH-expressing cells from human embryonic stem cells and induced pluripotent stem cells. We accomplished this through the comparison of multiple different basal media, the inclusion of the CDK inhibitor PD0332991 in both definitive endoderm and anterior foregut endoderm stages, and a 2-stage pharyngeal endoderm series. This is the first protocol to reproducibly establish PTH-expressing cells from human pluripotent stem cells and represents a first step toward the development of functional parathyroid cells with broad applicability for medicinal and scientific investigation.Lignocellulosic biomass conversion using cellulases/polygalacturonases is a process that can be progressively influenced by several determinants involved in cellulose microfibril degradation. This article focuses on the kinetics and thermodynamics of thermal inactivation of recombinant Escherichia coli cellulases, cel12B, cel8C and a polygalacturonase, peh 28, derived from Pectobacterium carotovorum sub sp. carotovorum. Several consensus motifs conferring the enzymes’ thermal stability in both cel12B and peh28 model structures have been detailed earlier, which were confirmed for the three enzymes through the current study of their thermal inactivation profiles over the 20-80°C range using the respective activities on carboxymethylcellulose and polygalacturonic acid. Kinetic constants and half-lives of thermal inactivation, inactivation energy, plus inactivation entropies, enthalpies and Gibbs free energies, revealed high stability, less conformational change and protein unfolding for cel12B and peh28 due to thermal denaturation compared to cel8C. The apparent thermal stability of peh28 and cel12B, along with their hydrolytic efficiency on a lignocellulosic biomass conversion as reported previously, makes these enzymes candidates for various industrial applications. Analysis of the Gibbs free energy values suggests that the thermal stabilities of cel12B and peh28 are entropy-controlled over the tested temperature range.Iron is required for the oxidative response of neutrophils to allow the production of reactive oxygen species (ROS). However, neutrophil function may be severely altered in conditions of iron overload, as observed in chronically transfused patients. Therefore, a tight regulation of neutrophil iron homeostasis seems to be critical for avoiding iron toxicity. Hepcidin is the key iron regulator in organisms; however, no studies have investigated its role in maintaining neutrophil iron homeostasis or characterized neutrophil function in patients with hereditary hemochromatosis (HH), a common iron overload genetic disorder that results from a defect in hepcidin production. To explore these issues, we studied 2 mouse models of iron overload an experimentally induced iron overload model (EIO), in which hepcidin is increased, and a genetic HH model of iron overload with a deletion of hepatic hepcidin. We found that iron-dependent increase of hepatic hepcidin results in neutrophil intracellular iron trapping and consecutive defects in oxidative burst activity.
