  2. 16. Carbohydrate Levels and Fructan Metabolism in Barley (Hordeum vulgare L.) Leaves : effects of manipulating mineral nutrition and photosynthesis

    Author : Changwen Wang; Björn Thorsteinsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysiologisk botanik; Physiological Botany;

    Abstract : Carbohydrate levels and fructan metabolism were studied in the leaves of barley (Hordeum vulgare L. cv. Agneta) plants subjected to phosphorous (P)-deficiency, nitrogen (N)-deficiency and N-resupply following the N-deficiency. READ MORE

  4. 17. The effects of deleterious mutations on ageing

    Author : Martin Iinatti Brengdahl; Urban Friberg; Dominic Wright; Thomas Flatt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ageing; Age-specific effects; Deleterious mutations; Drosophila melanogaster; Lifespan; Sex differences;

    Abstract : Ageing is defined as the deterioration of an individual's physiological performance with advancing age, which leads to a decrease in reproduction and/or survival. The question why most organisms age has preoccupied humans for millennia and, over the last decades, resulted in an ever-increasing research effort to understand this phenomenon. READ MORE

  5. 18. Carbon monoxide in biological systems : An experimental and clinical study

    Author : Anna-Maja Åberg; Jan-Erik Larsson; Dick Delbro; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbon monoxide; physiological effects; systemic inflammation; analytical method; blood; exhaled air; pharmacokinetics; cigarette smoking; blood donation; cytokines; Anaesthetics; Anestesiologi;

    Abstract : Background: Carbon monoxide (CO) is a toxic gas, but it is also produced endogenously when haem is degraded. When produced in vivo, CO is believed to have positive biological effects. For example it activates the production of cyclic guanosine mono-phosphate and causes vasodilatation. READ MORE

  6. 19. Ethanol from Lignocellulose: Physiological Effects of Inhibitors and Fermentation Strategies

    Author : Mohammad Taherzadeh Esfahani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; dilute-acid hydrolyzate; ethanol; hydroxymethyl furfural; furfural; acetic acid; lignocellulose; fed-batch; yeast; pantothenate; control; inhibition; HMF;

    Abstract : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). READ MORE

  7. 20. Physiological effects of apnoeic oxygenation using high-flow nasal oxygen

    Author : Ida-Maria Forsberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In anaesthetic practice, the inability to oxygenate and ventilate patients is a much-feared complication with risk for severe hypoxia-induced adverse outcomes. By administrating oxygen in the absence of spontaneous ventilation, apnoeic oxygenation may overcome these challenges by a prolonged time with sufficient oxygenation. READ MORE
