  2. 1. Fish for Food and Ecosystem Function : Fisheries, Trade and Key Ecosystem Processes in Coral Reefs

    Author : Matilda Thyresson; Magnus Nyström; Edward H. Allison; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fish; food; key ecosystem processes; functional groups; coral reefs; trade; gear; small-scale fisheries; social-ecological systems; Zanzibar; Tanzania; Western Indian Ocean; naturresurshushållning; Natural Resources Management;

    Abstract : Fish is a key source of food and income to millions of people living along tropical coastlines. They also play essential roles underpinning key ecosystem processes in coral reefs. For example, herbivorous fish keep algae in check that otherwise may outcompete corals, reducing the reef’s social-ecological values. READ MORE

  4. 2. Neuronal release and function of nitric oxide in smooth muscle

    Author : Henrik H Iversen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Autonomic neurotransmission; gastrointestinal tract; nitric oxide; nitric oxidesynthase; smooth muscle; urinary tract.;

    Abstract : The aim of the present thesis was to study nitric oxide (NO) as an effector molecule in autonomic neurotransmission. The nitrergic transmitter was examined with regard to its pharmacological profile, stimuli of release, release pattern, and effects in gastrointestinal and urinary tract smooth muscle. READ MORE

  5. 3. Mechanisms underlying mitochondrial function and biogenesis : implications for type 2 diabetes mellitus and obesity

    Author : Maria H Holmström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : mitochondria;

    Abstract : The ample supply of food, in conjunction with a sedentary lifestyle and certain genetic risk factors contribute to the rise in obesity, insulin resistance and type 2 diabetes mellitus. Reduced mitochondrial capacity for oxidative metabolism has been implicated as one possible cause of insulin resistance in several tissues; such as liver and skeletal muscle. READ MORE

  6. 4. Genetic and epigenetic influence on oxidative phosphorylation, islet function and type 2 diabetes in humans

    Author : Anders H Olsson; Diabetes - epigenetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Genetics; Epigenetics; Human Pancreatic Islets; Oxidative Phosphorylation; Insulin Secretion;

    Abstract : The prevalence of type 2 diabetes (T2D) is increasing worldwide. T2D is a heterogeneous disease caused by a complex interplay between multiple genetic, epigenetic and non-genetic factors. The disease is characterised by impaired insulin secretion from pancreatic β-cells and insulin resistance in peripheral tissues. READ MORE

  7. 5. A small amoeba at the crossroads of the big RNAi world : MicroRNA biogenesis and Argonaute function in Dictyostelium discoideum

    Author : Zhen Liao; Fredrik Söderbom; Gerhart E. H. Wagner; Christina Dixelius; Kriton Kalantidis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RNAi; microRNA; Argonaute protein; miRNA biogenesis; Dictyostelium discoideum; social amoeba; Dicer; development; growth; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Abstract : Small non-coding RNA (ncRNA) mediated gene silencing, known as RNAi, is a key regulatory mechanism of gene expression in eukaryotes. MicroRNAs (miRNA), one major type of small ncRNAs, are about 21nt long and bound by Argonaute proteins. READ MORE
