Throughout a 21-day culture period, osteogenically differentiated cells secreted mineralized matrix, and calcium deposits were observed throughout the scaffold. Under chondrogenic specific differentiation conditions, the cells modified their morphology from fibroblast-like to round cells and cartilage lacunas were observed as well as the deposit of cartilaginous matrix on the placental scaffolds. This experiment provides evidence, for the first time, that bovine placental scaffolds have the potential to support bovine mesenchymal stem cell adherence and differentiation into osteogenic and chondrogenic lineages. Therefore, the constructed material could be used for bone and cartilage tissue engineering.
  To examine the effects of an enteropeptidase inhibitor, SCO-792, on kidney function in rats.
 
  The pharmacological effects of SCO-792 were evaluated in Wistar fatty (WF) rats, a rat model of diabetic kidney disease (DKD).
 
  Oral administration of SCO-792 increased faecal protein content and improved glycaemic control in WF rats. SCO-792 elicited a rapid decrease in urine albumin-to-creatinine ratio (UACR). SCO-792 also normalized glomerular hyperfiltration and decreased fibrosis, inflammation and tubular injury markers in the kidneys. However, pioglitazone-induced glycaemic improvement had no effect on kidney variables. Dietary supplementation of amino acids (AAs), which bypass the action of enteropeptidase inhibition, mitigated the effect of SCO-792 on UACR reduction, suggesting a pivotal role for enteropeptidase. Furthermore, autophagy activity in the glomerulus, which is impaired in DKD, was elevated in SCO-792-treated rats. Finally, a therapeutically additive effect on UACR reduction was observed with a combination of SCO-792 with irbesartan, an angiotensin II receptor blocker.
 
  This study is the first to demonstrate that enteropeptidase inhibition is effective in improving disease conditions in DKD. SCO-792-induced therapeutic efficacy is likely to be independent of glycaemic control and mediated by the regulation of AAs and autophagy. Taken together with a combination effect of irbesartan, SCO-792 may be a novel therapeutic option for patients with DKD.

While proteolytically active proteases of multiple classes dominate, an increasing number of pseudoproteases have been discovered that have no proteolytic function but are pharmacologically active biomolecules, evolved to carry out alternative functions as regulatory, antihaemostatic, anti-inflammatory or immunomodulatory compounds. In this review, we provide an overview of proteases and pseudoproteases from clinically important arthropod parasites. Many of these act in central biological pathways of parasite survival and host-parasite interaction and may be potential targets for therapeutic interventions.Driven by the persisting poor understanding of the sluggish kinetics of the hydrogen evolution reaction (HER) on Pt in alkaline media, a direct correlation of the interfacial water structure and activity is still yet to be established. Herein, using Pt and Pt-Ni nanoparticles we first demonstrate a strong dependence of the proton donor structure on the HER activity and pH. The structure of the first layer changes from the proton acceptors to the donors with increasing pH. In the base, the reactivity of the interfacial water varied its structure, and the activation energies of water dissociation increased in the sequence the dangling O-H bonds less then the trihedrally coordinated water less then the tetrahedrally coordinated water. Moreover, optimizing the adsorption of H and OH intermediates can re-orientate the interfacial water molecules with their H atoms pointing towards the electrode surface, thereby enhancing the kinetics of HER. Our results clarified the dynamic role of the water structure at the electrode-electrolyte interface during HER and the design of highly efficient HER catalysts.Adolescent girls experience risks prior to pregnancy and giving birth that influence their overall health, and development, as well as community rates of infant mortality. Supporting adolescent girls through positive youth development (PYD) opportunities offers a potential long-term strategy to preventing infant mortality and improving maternal health outcomes. The current study sought to assess state-wide needs, resources and opportunities related to PYD supports for adolescent girls, especially among those most at risk for early pregnancy. A strengths, weaknesses, opportunities and threats (SWOT) analysis guided nine community forums in counties with the highest rates of infant mortality in one large Midwestern state. In total, 368 stakeholders attended the forums and provided insights related to the context of PYD for adolescent girls. Researchers also conducted three focus group with 19 parents/guardians and three focus groups with 25 adolescent girls aged 11-14 to validate the findings from the SWOT analysis. Content analysis was utilised to synthesise the qualitative results. Strengths and opportunities related to PYD for adolescent girls included access to afterschool programming and access to health and mental health services. Weaknesses brought awareness to more systemic problems as all nine counties reported a lack of communication and coordination among youth programs and a need for greater collaboration among youth agencies. Threats included challenges associated with technology and social media, unsafe neighbourhood conditions, and issues of racism, sexism, poverty and discrimination. Findings support the need for a continued focus and priority on improving access, services and supports for adolescent girls to prevent infant mortality and improve their health and well-being. Local, state and national leaders can use the results of this study to promote additional strategies for addressing infant mortality through PYD for adolescent girls.
