Determining a healthy reference range and factors potentially influencing PRO-C3 – A biomarker of liver fibrosis

2021

Background & Aims Progressive fibrosis has been identified as the major predictor of mortality in patients with non-alcoholic fatty liver disease (NAFLD). Several biomarkers are currently being evaluated for their ability to substitute the liver biopsy as the reference standard. Recent clinical studies in NAFLD/NASH patients support the utility of PRO-C3, a marker of type III collagen formation, as a marker for the degree of fibrosis, disease activity, and effect of treatment. Here we establish the healthy reference range, optimal sample handling conditions for both short- and long-term serum storage, and robustness for the PRO-C3 assay. Methods PRO-C3 was measured in 269 healthy volunteers…

The Carbon Footprint of Volunteer Tourism

2019

Abstract Tourism is growing at a fast rate and so is its carbon footprint. Alongside conventional tourism, a new form of tourism, so-called voluntourism, has emerged. The discussion on voluntourism in the existing literature has hereby mainly centred around its positive impacts on the health and education of communities and the local environment in developing countries. Nevertheless, little attention has been drawn to its climate impacts. This study set out to investigate the carbon footprint of voluntourism. The data were collected at a local non-governmental organisation (NGO) in India working with voluntourists. Both the carbon footprint of the stay in India and that from the round trip …

Reduction of olfactory sensitivity during normobaric hypoxia.

2018

Abstract Objective Acute mountain sickness (AMS) is caused by a low partial pressure of oxygen and may occur above 2500 m. The aim of this research was to evaluate olfactory and gustatory abilities of healthy subjects during baseline conditions and after seven hours of normobaric hypoxia. Methods Sixteen healthy subjects were assessed using the Sniffin’ Sticks, as well as intensity and pleasantness ratings. Gustatory function was evaluated utilizing the Taste Strips. Experiments were carried out under baseline conditions (518 m altitude) followed by a second testing session after seven hours of normobaric hypoxia exposure (comparable to 4000 m altitude). Results During normobaric hypoxia ol…

The Utility of BDNF Detection in Assessing Severity of Huntington's Disease.

2021

Brain-derived neurotrophic factor (BDNF) is involved in the survival and maturation of neurons, and also promotes and controls neurogenesis. Its levels are lowered in many neurodegenerative diseases, including Huntington’s disease (HD). Clinical pictures of HD can be very diverse, which makes it difficult to assess its severity

Pårørendes erfaringer med bruk av frivillige ved alvorlig sykdom i hjemmet

Next-of-kins’ experiences when using volunteers for palliative patients living at home The aim of this study was to illuminate next-of-kins’ experiences when using volunteers supplementing community health care services for palliative patients living at home. The study has a qualitative approach. Nine individual interviews were conducted with next of kin from a municipality in Southern Norway. Use of volunteers for palliative care in the home was a relief for next-of-kin, especially prominent for families who had limited social network. Planned volunteering resulted in the best results. Use of volunteer was also found helpful for families as they were given a "breathing space" and a certain…

Eight-week consumption of milk enriched with omega 3 fatty acids raises their blood concentrations yet does not affect lipids and cardiovascular dise…

2014

Adequate concentrations of omega 3 fatty acids (FA) may be maintained by consuming foods naturally rich in or functional foods enriched with those essential FA. We assessed the effects of an 8-week consumption of milk enriched with 400. mg of omega 3 FA on blood lipid levels and selected cardiovascular risk factors in adult healthy volunteers. Participants (n= 157) were randomized to consume - for eight weeks - either 500. mL/day of 1% fat milk providing 150. mg of eicosapentaenoic (EPA), 150. mg of docosahexaenoic (DHA), and 100. mg of α-linolenic (ALA) acids or 500. mL/day of non-enriched 1% fat milk. At week 8, we observed significant increments of blood EPA and DHA in the intervention g…

Effect of Bisacodyl on Intestinal Electrolyte and Water Net Transport and Transit

1987

The effect of bisacodyl on intestinal electrolyte, glucose, and water transport, and transit was studied in 6 healthy volunteers by intestinal perfusion. A 5-lumen tube with an occluding balloon allowed constant perfusion (10 ml/min) of 30 cm of the upper jejunum and a rapid collection of the perfusate free of contaminants. A phenol red bolus was injected into the tube and its passage through the test segment was calculated by dye dilution formula. A 1-hour control period was followed by a test period with 6 mg/h bisacodyl and followed by 2 other 1-hour control periods. Net absorption of Na+ (0.35 +/- 0.08 mmol/min) and water (1.7 +/- 0.6 ml/min) changed to net secretion (Na+ -0.93 +/- 0.3 …

Citizens AND HYdrology (CANDHY) : conceptualizing a transdisciplinary framework for citizen science addressing hydrological challenges

2021

Widely available digital technologies are empowering citizens who are increasingly well informed and involved in numerous water, climate, and environmental challenges. Citizen science can serve many different purposes, from the "pleasure of doing science" to complementing observations, increasing scientific literacy, and supporting collaborative behaviour to solve specific water management problems. Still, procedures on how to incorporate citizens' knowledge effectively to inform policy and decision-making are lagging behind. Moreover, general conceptual frameworks are unavailable, preventing the widespread uptake of citizen science approaches for more participatory cross-sectorial water go…
