The evaporative gas turbine pilot plant (EvGT) has been in operation at Lund Institute of Technology in Sweden since 1997. This article presents the latest development in the evaporative technology, the evaporation of bio-ethanol in a gas turbine power plant as a means to reduce the emission of greenhouse gases. Bio-ethanol is produced from a feedstock consisting of corn-stover, and the bio-ethano
Popular Abstract in Swedish Ärftliga näthinnesjukdomar med tidig debut Elektrofysiologiska och genetiska studier Ärftliga näthinnesjukdomar är den vanligaste orsaken till allvarligt synhandikapp hos unga människor i dagens Sverige. De flesta av dessa sjukdomar kan ännu inte behandlas, men vi har under de senaste åren fått allt större insikt i de bakomliggande sjukdomsmekanismerna, tack vare att Hereditary retinal degenerations are the most frequent reason for severe visual handicap among young people in Scandinavia today. In the six papers included in this thesis the phenotypic expressions, with emphasis on the electrophysiological findings, of five different juvenile hereditary retinal degenerations are described. The diagnoses have been confirmed by genetic analysis. The retinal disord
Popular Abstract in Swedish Typ 1-diabetes är en allvarlig, autoimmun, sjukdom och Sverige har världens näst högsta antal nya insjuknanden. Varje år diagnostiseras ca 700 individer i Sverige med sjukdomen som kan debutera i alla åldrar. Senare studier tyder dock på att barn med typ 1-diabetes blir allt yngre. Vi vet idag att ärftligheten är kopplad till en specifik gen vilket förklarar ca 30-50% aObjective The primary aim of this thesis was to test whether gestational exposure to environmental factors may induce islet autoimmunity. The second aim was to determine to what extent the exposure to viruses or other environmental factors is a risk factor for type 1 diabetes in the offspring. As children with type 1 diabetes have a higher risk of developing celiac disease (CD), an additional aim
Context: The European Association of Urology presents its guidelines for vasectomy. Vasectomy is highly effective, but problems can arise that are related to insufficient preoperative patient information, the surgical procedure, and postoperative follow-up. Objective: These guidelines aim to provide information and recommendations for physicians who perform vasectomies and to promote the provision
The overall aim of this thesis was to study life satisfaction (LS) and factors associated to LS in the group aged 78 and above. As an aid in interpreting the findings, Baltes’ and Baltes’ theory of selective optimisation with compensation (SOC) was used. All four studies included the same studypopulation who were followed for three years in the study Good Aging in Skåne, a national, randomized, po
The aims of this work were to evaluate objective and subjective signs of autonomic dysfunction (AD) in patients with primary Sjögren’s syndrome (pSS) and to evaluate its clinical associations. In study I, 46 pSS patients and 56/80/238 autonomic nervous function test (ANT) controls participated. Objective signs of AD were evaluated using three different cardiovascular ANTs and exocrine function in
Background: Tibial osteotomy is a treatment for younger and/or physically active patients suffering from uni-compartmental knee osteoarthritis. The open wedge osteotomy by the hemicallotasis technique includes the use of external fixation. The use of external fixation has several advantages, as early mobilization and the opportunity for optimal correction. However, the hemicallotasis technique has
Objective. To study to what extent geographical differences of the mortality from ischaemic heart disease (IHD) can be accounted for by the 28-day case fatality rate (CFR) following first hospital admittance for acute myocardial infarction (MI) and whether the geographical pattern of survival has any relationship with socio-economic circumstances. Design. Register-based surveillance study. Setting
Purpose: We investigated the value of serum measurements for glandular kallikrein 2 (hK2), and free (f) and total (t) prostate specific antigen (PSA) in a second round of biannual screening for prostate cancer. Materials and Methods: In 1995 to 1996, 5,853 of 9,811 randomly selected men in Goteborg, Sweden 50 to 66 years old had PSA measurements. Of 660 men 611 with tPSA 3 ng/ml or greater underwe
Background: Foods with a low glycemic index are increasingly being acknowledged as beneficial in relation to the insulin resistance syndrome. Certain organic acids can lower the glycemic index of bread products. However, the possible effect of acids in fermented milk products on the glycemic index and on insulinemic characteristics has not been addressed. The metabolic effects of fermented milk or
BACKGROUND: An early age at menarche, a short menstrual cycle length, and a high age at first full term pregnancy or nulliparity are known risk factors for breast cancer. These risk factors have previously been reported to differ between breast cancer patients with and without a family history of breast cancer and also between breast cancer patients and controls. METHODS: Self-administered questio
BACKGROUND: Individuals with low income have poorer health and should, therefore, have higher health expenditure than people with high income particularly in countries with a universal health care system. However, it has been discussed if social inequities in health diminish with age and we, hence, aimed to analyse this question. METHODS: We performed an age stratified cross-sectional analysis usi
BACKGROUND: Human exposure to persistent organic pollutants (POPs) is ubiquitous and found in all individuals. Studies have documented endocrine disrupting effects and impact on reproduction. The aim of the present study was to compare the level of xenoestrogenic activity in serum of groups with varying POP exposure, and to evaluate correlations to the POP biomarkers, 2,2',4,4',5,5'-hexachlorobiph
Popular Abstract in Swedish Blåsexstrofi är en ovanlig och mångfasetterad missbildning. I hela Sverige föds cirka tre barn om året med blåsexstrofi. Bukvägg och urinblåsa är öppna nedanför naveln, så att man ser blåsans insida samt rinnande urin. Flickorna har en delad clitoris, framflyttad och trång slidöppning samt framflyttad ändtarmsöppning. Pojkarna har en kort, öppen penis, som ligger uppfäl
Objective and Background: Pulse wave amplitude (PWA) derived from the digital vascular bed has been used in sleep studies. The nocturnal attenuation of PWA has been shown to reflect sympathetic activation during sleep. We assessed the relationship between nocturnal PWA attenuation and office blood pressure (BP). Methods: Eighty-one subjects (46 men; age 60 7 years: body mass index [BMI] 28.2 +/- 4
In an attempt to define clinically relevant models of akinesia and dyskinesia in 6-hydroxydopamine (6-OHDA)-lesioned rats, we have examined the effects of drugs with high (L-DOPA) vs. low (bromocriptine) dyskinesiogenic potential in Parkinson's disease on three types of motor performance, namely: (i) abnormal involuntary movements (AIMs) (ii) rotational behaviour, and (iii) spontaneous forelimb us
Anesthetized, paralyzed and mechanically ventilated pigs were exposed to extreme hypercapnia (PaCO2 approximately 20 kPa) at FiO2 0.4 for 480 min, with (n = 6) or without (n = 6) continuous infusion of isotonic buffers (bicarbonate and trometamol). Arterial pH was higher in buffered animals than controls, 7.21 +/- 0.01 vs 7.01 +/- 0.01 (mean +/- s.e.mean, P < 0.01). Serum osmolality and PaCO2 did
The evidence for anthropometric factors influencing breast cancer risk is accumulating, but uncertainties remain concerning the role of fat distribution and potential effect modifiers. We used data from 73,542 premenopausal and 103,344 postmenopausal women from 9 European countries, taking part in the EPIC study. RRs from Cox regression models were calculated, using measured height, weight, BMI an
Protein phosphorylation in the subcompartments of plant mitochondria was investigated by labelling with [gamma-32P]ATP and by SDS-PAGE/autoradiography. About 20 proteins in inside-out inner mitochondrial membranes from potato tubers were phosphorylated by endogenous protein kinases when incubated with [gamma-32P]ATP. None of the phosphorylated proteins were labelled when using [alpha-32P]ATP as a
Popular Abstract in Swedish Urininkontinens är en utbredd folksjukdom och ett stort folkhälsoproblem. Omkring 500 000 människor i Sverige, mest kvinnor (2/3) är drabbade. Förekomsten av inkontinens ökar med stigande ålder. Ofrivilligt urinläckage orsakar många gånger både medicinska och sociala handikapp med minskad livskvalitet som följd. Undersökningar har visat att endast 25% av de inkontinentaDysfunction of the pelvic floor can lead to incontinence and different forms of lower urinary tract symptoms (LUTS). Urinary incontinence is a common problem and about 500 000 persons in Sweden, mostly (2/3) women, suffering from incontinence. The general aim of this thesis was to characterize the function and dysfunction of the pelvic floor muscles in healthy and incontinent women. Vaginal EMG, p
