    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; outcomes; PAD; Diabetic foot ulcers;

    Abstract : The aim of the studies presented in this thesis was to study patients with diabetes and severe peripheral arterial disease (PAD) in regard to outcomes of foot ulcers, factors related to outcomes, and occurrences of new ulcerations and amputations following healing of the initial ulcer. Patients with diabetes and a foot ulcer, consecutively presenting at a multidisciplinary foot centre, with a systolic toe pressure . READ MORE

  4. 2. Nutrient cycling in agroecosystems: nitrogen cycling in southern Sweden in the 1850s and two Tanzanian villages in the 1990s

    Author : Lars-Erik Williams; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nutrient; nutrient model; nutrient cycling; nitrogen fixation; nitrogen budget; mixed system; miombo; manure; livestock; land use; historical system; food production; efficiency; crops; agroecosystem; carrying capacity; phosphorus; Scania; sustainability; Plant ecology; Växtekologi;

    Abstract : This study presents a general model for analysing nutrient cycling in agroecosystems. The focus is on food production intensity, human carrying capacity, sustainability and efficiency. The model can be used on systems including different kinds of land uses, which makes it applicable for studies on different scales. READ MORE

  5. 3. Relationships between Atmospheric Circulation and Wind Erosion in Southern Sweden and Australia

    Author : Marie Ekström; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Physical geography; geomorphology; Geologi; fysisk geografi; physical geography; Geology; sea level pressure; atmospheric circulation; erosivity; wind erosion; wind climatology; Scania; Australia;

    Abstract : Wind erosion is a serious threat to soil resources as it causes depletion of the fine fractions that may result in a less fertile soil. Wind erosion encompasses several processes of which many are related to climate variables. To date, there is little work performed on how wind erosion relates to climate and climate change.

  6. 4. Metabolic consequences of a Paleolithic diet in obese postmenopausal women

    Author : Caroline Blomquist; Tommy Olsson; Elin Chorell; Per-Arne Svensson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postmenopausal women; Paleolithic diet; randomized diet intervention; fat metabolism; low-grade inflammation; circulating fatty acids; diet validation; obesity; insulin resistance; Postmenopausala kvinnor; Paleolitisk kost; randomiserad kostintervention; fettmetabolism; fetma; låggradig inflammation; cirkulerande fettsyror; kostvalidering; fetma; insulin resistens; medicin; Medicine;

    Abstract : BackgroundObesity, in particular abdominal adiposity, is associated with elevated fatty acids and pro-inflammatory adipokines, which are linked to ectopic fat storage and insulin resistance. During menopause, there is a redistribution of fat from the peripheral to abdominal depots. READ MORE

  7. 5. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

    Author : Ulf Havelius; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

    Abstract : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.
