Kick-off meeting of the TOWWERS showcase project: 1 collaborative value-based healthcare anchored on real-world data involving the 5P.

The COVID-19 pandemic has highlighted the need to modernize healthcare systems to the reality of the 21st century. The first world-wide Strategic Committee to launch Collaborative Value-Based Healthcare (C-VBHC) anchored on populational Real World Data and structured collaboration, took place in Montreal, via TOWWERS showcase project. The meeting covered a broad range of topics from the perspective of each of the various Real-World healthcare actors, the 5P+: Patient, Prescriber, Producer, Policymaker, Payer, including Data and Research stakeholders.

The cysteine-rich domain of the secreted proprotein convertases PC5A and PACE4 functions as a cell surface anchor and interacts with tissue inhibitors of metalloproteinases.

The proprotein convertases PC5, PACE4 and furin contain a C-terminal cysteine-rich domain (CRD) of unknown function. We demonstrate that the CRD confers to PC5A and PACE4 properties to bind tissue inhibitors of metalloproteinases (TIMPs) and the cell surface. Confocal microscopy and biochemical analyses revealed that the CRD is essential for cell surface tethering of PC5A and PACE4 and that it colocalizes and coimmunoprecipitates with the full-length and C-terminal domain of TIMP-2.

Structure-function analysis of the prosegment of the proprotein convertase PC5A.

To investigate if some residues within the prosegment of PC5A are important for its optimal proteolytic function, various PC5A mutants were cellularly expressed, and their processing activities were compared using pro-vascular endothelial growth factor C (pro-VEGF-C) as a substrate. Although wild type PC5A almost completely processes pro-VEGF-C, a prosegment deletion as well as both P1 mutants of the primary (R116A) and secondary (R84A) autocatalytic cleavage sites are inactive. The in vitro inhibitory potency of various decapeptides mimicking the C-terminal sequence of PC5 prosegment (pPC5) revealed that the native (107)QQVVKKRTKR(116) peptide is a nanomolar inhibitor, whereas its P6 mutant K111H is more selective toward PC5A than Furin.

Effects of habitat fragmentation on provisioning rates, diet and breeding success in two species of tit (great tit and blue tit).

The aim of this study was to examine the effects of forest fragmentation on the ability of parent birds to provide their young with an adequate food supply. To examine whether prey population densities of the great tit (Parus major L.) and the blue tit (P.
