As an effective strategy to control the combustion of advanced combustion modes, the application of variable valve timing (VVT) in reactivity controlled compression ignition (RCCI) combustion was investigated in this study. By coupling KIVA-3V code with genetic algorithm, the combustion of a heavy-duty engine with RCCI combustion combined with VVT strategy was optimized under a wide load range. At

Background: Malaria parasites and related haemosporidian parasites are widespread and may cause severe diseases in birds. These pathogens should be considered in projects aiming breeding of birds for purposes of sustained ex situ conservation. Cranes are the 'flagship species' for health assessment of wetland ecosystems, and the majority of species are endangered. Malaria parasites and other haemo

Systemic lupus erythematosus (SLE) is an autoimmune disorder with heterogeneous clinical presentation and complex etiology involving the interplay between genetic, epigenetic, environmental and hormonal factors. Many common SNPs identified by genome wide-association studies (GWAS) explain only a small part of the disease heritability suggesting the contribution from rare genetic variants, undetect

Background: Different test procedures are often used within performance-based measures, causing uncertainty as to whether results can be compared between studies. Thus, the aim of this study was to assess agreement between different test procedures for the single-leg hop for distance (SLHD) and the single-leg mini squat (SLMS), respectively, two commonly used tasks for assessing deficiency in lowe

Introduction: We wanted to determine vitamin D status after gestational diabetes mellitus (GDM) and to evaluate whether levels of 25-hydroxyvitamin D3 (25OHD3) are associated with beta cell function, insulin resistance or a diagnosis of diabetes after GDM. Material and methods: Glucose homeostasis was assessed during a 75-g oral glucose tolerance test one to two years after delivery in 376 women w

Background: Papillary thyroid cancer is treated with total/near-total thyroidectomy (TT) with or without central lymph node dissection (CLND), depending on risk factors and tumour size. Balancing the risk of disease recurrence and surgical morbidity remains a challenge. A population-based nationwide study was undertaken to evaluate the risk of permanent hypoparathyroidism associated with CLND. Met

The relationship between temperature and mortality is well established but has seldom been investigated in terms of external causes. In some Eastern European countries, external cause mortality is substantial. Deaths owing to external causes are the third largest cause of mortality in Estonia, after cardiovascular disease and cancer. Death rates owing to external causes may reflect behavioural cha

Purpose: To investigate the possible differences between SPECT/CT based whole-remnant and maximum-voxel dosimetry in patients receiving radio-iodine ablation treatment of differentiated thyroid cancer (DTC). Methods: Eighteen DTC patients were administered 1.11 GBq of 131I-NaI after near-total thyroidectomy and rhTSH stimulation. Two patients had two remnants, so in total dosimetry was performed f

Reducing the prevalence of mastitis caused by Staphylococcus aureus (S. aureus) is essential to improve animal health and reduce economic losses for farmers. The clinical outcome of acute mastitis and risk of progression to persistent mastitis can, at least to some extent, be related to genetic variants of the strain causing the infection. In the present study we have used microarrays to investiga

Background: The UICC TNM 7th edition introduced stage groups for anal cancer which in 2019 has not yet come into general use. The new TNM 8th edition from 2016 defines 7 sub-stages. Background data for these changes are lacking. We aimed to investigate whether the new classification for anal cancer reliably predict the prognosis in the different stages. Patients and methods: The Nordic Anal Cancer

In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. This frozen water is not available to the energy producers until the spring snow melt when as much as 70% of the annual dischar

Popular Abstract in Swedish Prostanoider, en samlingsbeteckning för prostaglandiner och tromboxaner, tillverkas av de flesta av kroppens olika celltyper och fungerar som en slags hormoner i många olika organsystem i människor och djur. Prostanoiderna bildas alla från prostaglandin H2 som i sin tur tillverkas av enzymet cyklooxygenas (COX) från fettsyran arachidonsyra. Prostanoiderna är alltså fettProstanoids are ubiquitously distributed lipid signaling molecules derived from arachidonic acid, that exhibit numerous and diverse biological effects in a variety of physiological and pathophysiological conditions. The cell surface receptors for the prostanoids belong to the family of G protein-coupled receptors. In this thesis, the author describes the cloning and structural characterization of

The genes coding for human and mouse AMACO, an extracellular matrix protein containing VWA-like domains related to those in MAtrilins and COllagens, were detected in databases, the cDNAs were cloned, and the primary structures were deduced from the nucleotide sequences. The genes consist of 14 exons and have a similar exon/intron organization. The protein consists of a signal peptide sequence, an

Background: Gambling disorder is associated with increased suicidality, especially in women who also are more likely to have psychiatric comorbid disorders and more often have experiences of traumatic life events. Although suicidality is increased and several risk factors have been identified, knowledge of the suicidal process is lacking, especially for women. Aim: To explore the lived experiences

Objective: To study the difference in incidence and risk of fragility fractures between rheumatoid arthritis (RA) patients followed up early in the disease and the general population in Sweden; and the fracture risk changes in RA patients diagnosed in the 1990s and 2000s because of earlier, more potent pharmacological treatment in the later period. Method: Patients with early RA were recruited fro

Objective: To examine the relation of well-known factors of the metabolic syndrome (MetS) as well as related circulating factors, with risk of colorectal cancer. Methods: We performed a case control study of 306 colorectal cancer cases and 595 matched controls nested in the Northern Sweden Health and Disease Cohort. Levels of C-peptide, glycated haemoglobin (HbA1c), leptin and adiponectin were mea

Objectives Evaluate the natural course of anterior cruciate ligament (ACL) healing on MRI within 5 years of acute ACL rupture and compare 2-year and 5-year outcomes based on healing status and treatment group. Methods Secondary analysis of 120 Knee Anterior Cruciate Ligament Nonsurgical vs Surgical Treatment (KANON) trial participants randomised to rehabilitation and optional delayed ACL reconstru
