  2. 1. Salivary glands and oral lesions in diabetes mellitus : an experimental and clinical study with special reference to the influence of metabolic control and duration of the disease

    Author : Carl-Olof Reuterving; Erik Hägg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes mellitus; salivation; salivary glucose; saliva; submandibular gland; pilocarpine; root surface caries; periodontal disease; alloxan; feeding behavior; rats; humans;

    Abstract : Diabetes mellitus is associated with several clinically significant abnormalities in the oral cavity and salivary glands, the most common being periodontitis, salivary gland enlargement and a sensation of dry mouth. The pre­valence of dental caries in diabetics is mostly reported to be decreased or unaffected. READ MORE

  4. 2. Effects of warming and nutrient enrichment on feeding behavior, population stability and persistence of consumers and their resources

    Author : Wojciech Uszko; Sebastian Diehl; Lennart Persson; David Vasseur; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; consumer-resource; Daphnia; functional response; nutrient enrichment; parameter estimation; persistence; plankton; predator-prey; stability; temperature; type II; type III; warming;

    Abstract : Consumer-resource interactions are the basic building blocks of every food web. In spite of being a central research theme of longstanding interest in ecology, the mechanisms governing the stability and persistence of consumer-resource interactions are still not entirely understood.

  5. 3. The Invasion of the Zebra Mussel - Effects on Phytoplankton Community Structure and Ecosystem Function

    Author : Rahmat Naddafi; Kurt Pettersson; Peter Eklöv; Willem Goedkoop; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Invasive species; Zebra mussel; Invasion success; Selective feeding; Non-lethal effects of predator; Seston stoichiometry; Delayed fluorescence excitation spectroscopy; Phytoplankton dynamics; Trait-mediated indirect interaction; Ecosystem function;

    Abstract : Biological invasion has become a major threat to economy, ecology, global biodiversity and ecosystem function of aquatic ecosystems. The main aim of the thesis was to study the effects of the zebra mussel (Dreissena polymorpha), a versatile invasive species, on phytoplankton dynamics and ecosystem function of lakes. READ MORE

  6. 4. Hypothalamic neuronal circuits involved in the regulation of food intake and body weight : histochemical studies in lean rats and obese mutant mice

    Author : Matilda Bäckberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : AGRP; arcuate nucleus; BBB; CART; GABA; GABA receptors; immunohistochemistry; in situ hybridization; hypothalamus; LHA; leptin; MCH; NPY; orexin; POMC; tubby;

    Abstract : Obesity is a major health problem because of its dramatic increase in prevalence and its association with type 2 diabetes, coronary heart diseases, hypertension and stroke. It is well known that signals generated in response to feeding behavior are integrated in the brain. READ MORE

  7. 5. Regulation of insulin signaling and its developmental and functional roles on peptidergic neurons in the Drosophila central nervous system

    Author : Jiangnan Luo; Dick Nässel; Susan Broughton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insulin; serotonin; octopamine; insulin receptor; Dimm; neuropeptide; funktionell zoomorfologi; Functional Zoomorphology;

    Abstract : In Drosophila, eight insulin-like peptides (DILP1-8) are produced and secreted in different locations. They regulate many aspects of development and physiology, such as organism growth, metabolic homeostasis, reproduction, stress resistance and life span. READ MORE
