We describe our experience of 30 consecutive children supported with ECMO and receiving 20 ppm of nitric oxide in the oxygenator of the ECMO circuit. Administration of nitric oxide into the ECMO circuit is safe and could potentially mitigate ischaemia reperfusion injury and end-organ dysfunction of children requiring mechanical support.

Peliosis hepatis (PH) is a rare, benign condition of the liver characterized by the presence of blood-filled lacunar spaces in the parenchyma. It usually has a chronic presentation and is a rare cause of portal hypertension reported in adult patients. Its etiology is diverse and ranges from infectious agents to tumors to toxic substances and anabolic steroids; however, the cause remains unclear in 25-50% of patients. Similarly, the symptomatology and imaging findings are diverse. Biopsy is the definitive test to diagnose the condition...

BACKGROUND AND AIMS: Beta-blockers provide secondary prophylaxis following endoscopic therapy for variceal bleeding. Guidelines recommend starting beta-blockers 6 days after endoscopy to prevent masking hemodynamic signs of re-bleeding. We aimed to see safety of earlier initiation of betablockers. METHODS: Cirrhotic patients with upper GI bleed were given intravenous vasoactive agents until undergoing endoscopy. Patients with only oesophageal varices as source of bleed were recruited...

Papers and textiles that treated with per- and polyfluoroalkyl substances (PFASs) are sources of human and environmental exposure. Data for individual PFASs, such as perfluorooctane sulfonate (PFOS) and perfluroooctanoate (PFOA), are not placed into the context of total fluorine for papers and textiles. Gas chromatography mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to quantify volatile and ionic PFASs, respectively, and the total oxidizable precursor (TOP) assay was used to quantify precursors that form perfluoroalkyl carboxylates...

OBJECTIVE: Behavioural interventions, such as smoke-free signage, are used to support air quality in public outdoor spaces that are not protected by a smoke-free policy, such as states with preemptive clause legislation. However, there is little evidence of the effectiveness of these interventions. This paper is an evaluation of whether smoke-free signage posted in public parks altered smoking behaviours of park patrons. METHODS: A time-series quasi-experimental design was used...

The anterior cingulate gyrus (ACG) is a continued focus of research as its exact role in brain function and vast connections with other anatomical locations is not fully understood. A review of the literature illustrates the role the ACG likely plays in cognitive and emotional processing, as well as a modulating role in motor function and goal-oriented behaviors. While lesions of the cingulate gyrus are rare, each new case broadens our understanding of its role in cognitive neuroscience and higher order processing...

Cyanine dyes show a general propensity to localize to polarized mitochondria. This mitochondriotropism was used to perform a copper-free click reaction in the mitochondria of living cells. The in organello reaction of a Cy3 and Cy5 dye led to a product that was easily traceable by Förster resonance energy transfer (FRET). As determined by confocal laser scanning microscopy, the Cy3-Cy5 conjugate showed enhanced retention in mitochondria as compared to the starting compounds. This enhancement of a favorable property can be achieved by synthesis in organello but not outside mitochondria...

INTRODUCTION: Ano-rectal abscesses are common. They however usually do not present with abdominal symptoms. CT although useful is not routinely carried out. Finding of Pneumo-retro-peritoneum with ischio-rectal abscess is rare. CASE PRESENTATION: We present the case of a diabetic gentleman who presented with abdominal pain and distension and was found to have ischio-rectal abscess on perianal examination. Although initially suspected to have acute abdomen due to perforated viscus, CT scan revealed pneumo-retro-peritoneum which appeared to arise due to the abscess...

The decreasing cost of genomic technologies has enabled the molecular characterization of large-scale clinical disease samples and of molecular changes upon drug treatment in various disease models. Exploring methods to relate diseases to potentially efficacious drugs through various molecular features is critically important in the discovery of new therapeutics. Here we show that the potency of a drug to reverse cancer-associated gene expression changes positively correlates with that drug's efficacy in preclinical models of breast, liver and colon cancers...

OBJECTIVES: Obesity prevalence among people living with HIV (HIV+) is rising. HIV and obesity are proinflammatory states, but their combined effect on inflammation (measured by interleukin 6, IL-6), altered coagulation (D-dimer), and monocyte activation (soluble CD14, sCD14) is unknown. We hypothesized inflammation increases when obesity and HIV infection co-occur. METHODS: The Veterans Aging Cohort Study survey cohort is a prospective, observational study of predominantly male HIV+ veterans and veterans uninfected with HIV; a subset provided blood samples...
