Data pipeline for managing field experiments.

As agricultural and environmental research projects become more complex, increasingly with multiple outcomes, the demand for technical support with experiment management and data handling has also increased. Interactive visualisation solutions are user-friendly and provide direct information to facilitate decision making with timely data interpretation. Existing off-the-shelf tools can be expensive and require a specialist to conduct the development of visualisation solutions. We used open-source software to develop a customised near real-time interactive dashboard system to support science experiment decision making. Our customisation allowed for: • Digitalised domain knowledge via open-source solutions to develop decision support systems. • Automated workflow that only executed the necessary components. • Modularised solutions for low maintenance cost and upgrades.

Sustained activation of c-Jun N-terminal and extracellular signal-regulated kinases in port-wine stain blood vessels.

BACKGROUND: Port-wine stain (PWS) is a congenital, progressive vascular malformation but the pathogenesis remains incompletely understood. OBJECTIVE: We sought to investigate the activation status of various kinases, including extracellular signal-regulated kinase, c-Jun N-terminal kinase, AKT, phosphatidylinositol 3-kinase, P70 ribosomal S6 kinase, and phosphoinositide phospholipase C γ subunit, in PWS biopsy tissues. METHODS: Immunohistochemistry was performed on 19 skin biopsy samples from 11 patients with PWS. RESULTS: c-Jun N-terminal kinase, extracellular signal-regulated kinase, and P70 ribosomal S6 kinase in pediatric and adult PWS blood vessels were consecutively activated. Activation of AKT and phosphatidylinositol 3-kinase was found in many adult hypertrophic PWS blood vessels but not in infants. Phosphoinositide phospholipase C γ subunit showed strong activation in nodular PWS blood vessels. LIMITATION: Infantile PWS sample size was small. CONCLUSION: Our data suggest a subsequent activation profile of various kinases during different stages of PWS: (1) c-Jun N-terminal and extracellular signal-regulated kinases are firstly and consecutively activated in all PWS tissues, which may contribute to both the pathogenesis and progressive development of PWS; (2) AKT and phosphatidylinositol 3-kinase are subsequently activated, and are involved in the hypertrophic development of PWS blood vessels; and (3) phosphoinositide phospholipase C γ subunit is activated in the most advanced stage of PWS and may participate in nodular formation.

Bronchoscopic intervention obviates the need for continued mechanical ventilation in patients with airway obstruction and respiratory failure from inoperable non-small-cell lung cancer.

BACKGROUND: Patients with advanced non-small-cell lung cancer (NSCLC) and acute respiratory failure (ARF) from central airway obstruction (CAO) may be offered end-of-life care rather than intensive care treatment and palliative bronchoscopic intervention. OBJECTIVES: To determine whether bronchoscopic intervention could be immediately successful in restoring airway patency and obviate the need for continued mechanical ventilation in a homogeneous group of inoperable mechanically ventilated patients with ARF and CAO from NSCLC. METHODS: A retrospective study of 12 consecutive intubated and mechanically ventilated patients with inoperable or unresectable CAO from NSCLC referred for therapeutic bronchoscopic intervention between January 2003 and December 2008. Outcome measures included time-to-postintervention extubation and survival. Procedural success was defined as successful restoration of airway patency, extubation and removal from mechanical ventilation within 24 h after bronchoscopic intervention. RESULTS: Twelve intubated and mechanically ventilated patients were admitted to the ICU during the 6-year study period. Airway patency was restored in 11/12 (91%) patients. Bronchoscopic intervention resulted in immediate extubation and discontinuation of mechanical ventilation in 9/12 (75%) patients. Overall median survival was 228 days (range 6-927). For the 9 patients extubated within 24 h after intervention, however, median survival was 313 days (range 6-927). CONCLUSIONS: Intubated patients with respiratory failure caused by CAO from NSCLC can be successfully and rapidly removed from mechanical ventilation after bronchoscopic interventions aimed at restoring airway patency. Median survival greater than 10 months justifies ICU hospitalization and referral for bronchoscopic treatment.
