  1. 1. Perturbance and Stimulation : using Nitrogen Addition and High-Throughput Sequencing to Study Fungal Communities in Boreal Forests

    Författare :Andreas N. Schneider; Nathaniel Street; Vaughan Hurry; Torgny Näsholm; Colin Averill; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Boreal forest; Scots pine; Norway spruce; ectomycorrhiza; saprotroph; fertilization; nitrogen; mycobiome; rhizosphere; decomposition; carbon; seedling establishment; forest management; clearcutting;

    Sammanfattning : Fungal communities are major players in globally important nutrient cycling processes, and form symbioses with most terrestrial plants. In the nitrogen (N) limited Swedish boreal forest, ectomycorrhizal (EcM) fungi colonize most roots of the economically important and stand dominating conifer species, Norway spruce (Picea abies) and Scots pine (Pinus sylvestris), with significant implications for tree nutrition and decomposition processes.

  2. 2. Swallowing and deep brain stimulation : swallowing function in Parkinson's disease after subthalamic nucleus and caudal zona incerta deep brain stimulation

    Författare :Stina Sundstedt; Katarina Olofsson; Göran Laurell; Fredrik Karlsson; Umeå universitet; []

    Sammanfattning : Background Swallowing problems are common in Parkinson’s disease, and these affect morbidity and mortality largely due to aspiration-induced pneumonia. Even mild dysphagia affects patient Quality of Life. LÄS MER

  3. 3. Retinal glucose metabolism and blood flow : Effects of photic stimulation

    Författare :Lin Wang; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; blood flow; darkness; flicker; glucose oxidation; glycolysis; lactate; light; nitric oxide; optic nerve; retina; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : Retinal glucose metabolism was investigated under different light conditions in cats,pigs and rabbits. Glycolysis and glucose oxidation in the outer and inner parts of theretina were assessed by determining arteriovenous concentration differences foroxygen, glucose and lactate, as well as local blood flow.

    Sammanfattning : Deep Brain Stimulation (DBS) is an established therapy that is predominantly  utilized in treating the symptoms of neurodegenerative diseases such as Parkinson's Disease and Essential Tremor, crippling diseases like Chronic Pain and Epilepsy, and psychiatric diseases such as Schizophrenia and Depression. Due to its invasive nature, DBS is considered as a last resort therapy. LÄS MER
