Impediments to peace.

While effective institutional practices are critical for the evolution of peace certain factors deter their effectiveness. In-group and out-group dynamics may make peace difficult between culturally distinct groups. Critical ecological conditions often lead to intractable conflict over resources.

Evaluation of the matrix metalloproteinase 9 (MMP9) inhibitor Andecaliximab as an Anti-invasive therapeutic in Head and neck squamous cell carcinoma.

Objectives: Locoregional and lymphovascular involvement of invasive head and neck squamous cell carcinoma (HNSCC) complicates curative treatment. Matrix metalloproteinase (MMP) 9 is a negative prognostic marker in HNSCC and targets multiple extracellular matrix (ECM) substrates, where it contributes to breaching basement membrane and stromal barriers enabling invasive spread. Andecaliximab (ADX) is a second-generation MMP9 inhibitor well tolerated in clinical trials of gastric and pancreatic adenocarcinoma.

Diurnal Differences in Intracellular Replication Within Splenic Macrophages Correlates With the Outcome of Pneumococcal Infection.

Circadian rhythms affect the progression and severity of bacterial infections including those caused by , but the mechanisms responsible for this phenomenon remain largely elusive. Following advances in our understanding of the role of replication of within splenic macrophages, we sought to investigate whether events within the spleen correlate with differential outcomes of invasive pneumococcal infection. Utilising murine invasive pneumococcal disease (IPD) models, here we report that infection during the murine active phase (zeitgeber time 15; 15h after start of light cycle, 3h after start of dark cycle) resulted in significantly faster onset of septicaemia compared to rest phase (zeitgeber time 3; 3h after start of light cycle) infection.

A Novel Percutaneous Technique for Left Ventricular Assist Device Deactivation Using a Left Atrial Appendage Occluder in the Outflow Cannula.

Reverse cardiac remodeling may occur in some left ventricular assist device (LVAD) recipients. Although considered the standard therapy, surgical device explantation with repeat sternotomy might be undesirable or very high risk. On the other hand, there are few data reporting minimally invasive percutaneous LVAD deactivation.

Interaction of with tissue macrophages in a mouse infection model and ex-vivo pig organ perfusions: an exploratory investigation.

Background: Hypervirulent (hv) strains of capsule type K1 and K2 cause invasive infections associated with hepatic abscesses, which can be difficult to treat and are frequently associated with relapsing infections. Other strains (non-hv), including lineages that have acquired carbapenem resistance, do not manifest this pathology. In this work we aimed to test the hypothesis that within-macrophage replication is a key mechanism underpinning abscess formation in hv infections.
