Vesicular stomatitis virus (VSV) is a member of the order Mononegavirales, which consists of viruses with a genome of nonsegmented negative-sense (NNS) RNA. Many insights into the molecular biology of NNS viruses were first made in VSV, which is often studied as a prototype for members of this order. Like other NNS viruses, the VSV RNA polymerase consists of a complex of the large protein (L) and phosphoprotein (P). Recent discoveries have produced a model in which the N-terminal disordered segment of P (PNTD) coordinates the C-terminal accessory domains to produce a "compacted" L conformation. Despite this advancement, the role of the three phosphorylation sites in PNTD has remained unknown. Using nuclear magnetic resonance spectroscopy to analyze the interactions between PNTD and the L protein C-terminal domain (LCTD), we demonstrated our ability to sensitively test for changes in the interface between the two proteins. This method showed that the binding site for PNTD on LCTD is longer than was previously ts effects on L conformation suggest that the structural picture of L during infection might be more complex than previously appreciated.Adeno-associated viruses (AAV) have attracted significant attention in the field of gene and cell therapy due to highly effective delivery of therapeutic genes into human cells. The ability to generate recombinant AAV vectors compromised of unique or substituted protein sequences has led to the development of capsid variants with improved therapeutic properties. Seeking novel AAV vectors capable of enhanced transduction for therapeutic applications, we have developed a series of unique capsid variants termed AAV X-Vivo (AAV-XV) derived from chimeras of AAV12 VP1/2 sequences and the VP3 sequence of AAV6. These AAV variants showed enhanced infection of human primary T cells, hematopoietic stem cells, and neuronal cell lines over wildtype parental viruses, and superiority over AAV6 for genomic integration of DNA sequences by AAV alone or in combination with CRISPR gene editing. AAV-XV variants demonstrate transduction efficiency equivalent to AAV6 at multiplicities of infection 2 logs lower, enabling T cell engihigh, which has resulted in unfortunate recent safety concerns and deaths in patients given higher-dose AAV gene therapy. We have generated new AAV variants possessing unique combinations of capsid proteins for gene and cell therapy applications termed AAV-XV, which have high levels of cell transduction and gene delivery at lower MOI. Furthermore, we demonstrate a novel finding, and an important consideration for recombinant AAV design, that a region of the AAV genome encoding the capsid viral protein and AAP is critical for both virus yield and the enhancement of infection/transduction.
  Ghana's shift from low-income to middle-income status will make it ineligible to receive concessional aid in the future.  https://www.selleckchem.com/products/leupeptin-hemisulfate.html  While transition may be a reflection of positive changes in a country, such as economic development or health progress, a loss of support from donor agencies could have negative impacts on health system performance and population health. We aimed to identify key challenges and opportunities that Ghana will face in dealing with aid transition, specifically from the point of view of country-level stakeholders.
 
  We conducted key informant interviews with 18 stakeholders from the government, civil society organisations and donor agencies in Ghana using a semistructured interview guide. We performed directed content analysis of the interview transcripts to identify key themes related to anticipated challenges and opportunities that might result from donor transitions.
 
  Overall, stakeholders identified challenges more frequently than opportunities. All stakeholders interviewed believe that Ghtment to health. The loss of aid could be turned into an opportunity to integrate vertical programmes into a more comprehensive health system.
 Stakeholders in Ghana believe transitioning away from aid for health presents both challenges and opportunities. The challenges could be addressed by conducting a transition readiness assessment, identifying health sector priorities, developing a transition plan with a budget to continue critical health programmes and mobilising greater political commitment to health. The loss of aid could be turned into an opportunity to integrate vertical programmes into a more comprehensive health system.
  Indigenous communities worldwide are leading calls for all research involving Indigenous people to be underpinned by values and principles articulated by them. Many researchers are explicitly adopting these principles to guide what, where, how and when research is undertaken with Indigenous people. With critical reflection to support the implementation of such principles largely absent from published literature, this paper explores both the implementation of, and the outcomes from a set of guiding principles used in a large-scale Australian research collaboration to improve Indigenous health.
 
  In this inductive qualitative study, we adopted a principles-focused evaluation approach. Based on interviews with 35 actors in the collaboration and a review of project documents, we generated themes that were then iteratively discussed, refined and categorised into (1) 'strategies'-activities by which implementation of our guiding principles were recognised; (2) 'outcomes'-results seen from implementing the principion platform' approach.
 
  Our findings show that principles guiding collaborations are valuable in providing a focus, direction and a way of working together when they are collaboratively developed, hold genuine meaning for all members and are implemented within a culture of continuous critical reflection, learning and adaptation, with ongoing reinterpretation of the principles over time.
