Method: A population-based sample of 1886 twins aged 9 and 12, enriched for childhood mental health problems, was recruited from the Child and Adolescent Twin Study in

Popular Abstract in Swedish Syftet med min avhandling är att utforska vilken funktionell roll naturliga mördar T (NKT) -celler har, samt vilka gener som är viktiga för dessa celler. NKT-celler utgör en liten men specialiserad undergrupp av T-celler, och är mycket intressanta eftersom att de, trots att de tillhör det specifika immunförsvaret, även har receptorer och egenskaper som är starkt förknipThis thesis focuses on a small population of non-conventional T lymphocytes, called natural killer T (NKT) cells. NKT cells have many unique features; such as recognition of glycolipids presented by CD1d, expression of NK receptors and rapid production of large amounts of cytokines, such as IL-4 and IFN-gamma,?upon activation. This early and robust cytokine burst is believed to give NKT cells the

PURPOSE. Integration between subretinal grafts and the host retina is limited in part by the presence of a barrier at the graft-host interface. This study was conducted to identify factors that may contribute to this barrier, by examining the distribution of glial structures and associated molecules in different setups of overlapping retinal pieces. METHODS. Neuroretinal tissue derived from mice t

Popular Abstract in Swedish Skador i knäleden är vanligt förekommande och främre korsbandsskada drabbar i Sverige årligen mer än 8 per 10 000 personer i åldern 10-64 år. Följderna av skadan kan bli bestående funktionsnedsättning med bl.a. instabilitet, plötsliga och smärtsamma knäledsvikningar och ökad risk för nya skador. Cirka hälften av patienterna utvecklar ledsvikt (artros) 10-15 år efter denThe purpose of this thesis was to increase the understanding of altered movement patterns in individuals with anterior cruciate ligament (ACL) injury in order to improve ACL rehabilitation, and to develop an observational instrument termed Test for Substitution Patterns (TSP) for standardized, quantifiable scoring of altered movement patterns in legs and trunk. In all, 142 participants, 93 with A

Background: The accepted standard for assessing the wellbeing of the newborn is the Apgar score and blood gas analysis. However, the prediction of neonatal morbidity or mortality is limited. In small-for-gestation (SGA) fetuses at 18-38 weeks of gestation, pO(2) is <5th centile both in the umbilical artery and vein in 30%. In a previous study in singleton term neonates cardiac specific enzymes (B-

Objective. To investigate the occurrence of extraarticular manifestations (ExRA) in it well defined community based cohort of patients with rheumatoid arthritis (RA), and to examine their effect on mortality, Methods. Using the resources of the Rochester Epidemiology Project. a retrospective medical record review was conducted of a cohort of 424 cases of RA in Olmsted County, MN, USA, diagnosed du

Background Systemic lupus erythematosus (SLE) is a clinically heterogeneous disease in which the risk of disease is influenced by complex genetic and environmental contributions. Alleles of HLA-DRB1, IRF5, and STAT4 are established susceptibility genes; there is strong evidence for the existence of additional risk loci. Methods We genotyped more than 500,000 single-nucleotide polymorphisms (SNPs)

The toxicity of different phenols to the soil bacterial community was studied in the laboratory using the leucine incorporation technique. The effects of environmental factors such as pH, temperature and binding strength to soil particles were also assessed in order to deduce confounding effects due to the chemical and physical conditions in the soil from which the bacterial community was extracte

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in women after menopause. In essence major risk factors for CVD are similar in women as for men inclusive of serum lipid perturbations. The effects of estrogens and hormone replacement therapy on lipid metabolism is widely discussed and warrant further evaluation especially when combined with other lipid lowering drugs. STUDY D

The purpose of this study was to characterize the emissions of a large number of chemical compounds emitted from birch wood combustion in a wood stove. Birch wood is widely used as fuel in Swedish household appliances. The fuel load was held constant during six experiments. Particles < 2.5 mum diameter were collected and the size distribution of the particles was measured. The results were compare

Swedish agriculture is currently undergoing radical changes with respect to the working environment. New production milking systems may alter the physical workload and thus have an effect on the development of musculoskeletal disorders. Earlier studies have shown that there is a manifest risk of suffering injury to the forearm, wrist and hand during machine milking especially during the attaching

AIM: The study aimed to investigate long-term consequences of respiratory syncytial virus (RSV) positive acute lower respiratory tract infection (ALRI) in a low-income country according to severity of the initial infection. DESIGN: The study was a 1:1 matched case-control study of 335 RSV case children and 335 control children. The mean age of RSV ALRI was 0.9 year and at follow-up, 6.8 years. Cas

Purpose: We evaluated the significance of focal prostate cancer found in sextant biopsies in men participating in a biennial prostate specific antigen (PSA) based screening program. Materials and Methods: In 1995, 10,000 men 50 to 65 years old were randomized to biennial screening with PSA testing. Sextant biopsies were recommended when total PSA was 3 ng/ml or greater at screening rounds 1 and 2,

ABSTRACT: BACKGROUND: In Guinea-Bissau HIV-1, HIV-2, and HTLV-I are prevalent in the general population. The natural history of HIV/HTLV-I single and dual infections has not been fully elucidated in this population. Previous studies have shown that combinations of these infections are more common in older women than in men. The present study compares mortality associated with HIV-1, HIV-2, and HTL

OBJECTIVE: To study the possibility of improving blood lipids, glucose tolerance and insulin sensitivity in women with impaired glucose tolerance and a history of gestational diabetes by merely changing the glycaemic index (GI) and dietary fibre (DF) content of their bread. DESIGN: Randomized crossover study where test subjects were given either low GI/high DF or high GI/low DF bread products duri

OBJECTIVES. The aim of the present study was to describe the 5-year incidence of retinopathy in type 1 diabetes mellitus and to characterize risk indicators for the development and progression of retinopathy. DESIGN. A cross-sectional study of type 1 diabetic patients taken care of at a medical department. SETTING. All type 1 diabetic patients attending the Department of Internal Medicine, Univers

OBJECTIVE: Nitric oxide (NO) and oxygen free radicals are implicated in the pathophysiology of traumatic brain injury (TBI). Peroxynitrite formation from NO and superoxide contributes to secondary neuronal injury but the neuroprotective effects of nitric oxide synthase (NOS)-inhibitors have been contradictory. This study was undertaken to examine whether PTtic administration of the (NOS)-inhibitor

It has been demonstrated that prostate-specific antigen (PSA), in spite of its name, can be detected in body fluids and tumors from a variety of organs. Investigations have shown that human glandular kallikrein 2 (hK2), a related prostate-secreted protease, can activate the zymogen form of PSA, suggesting that the two enzymes might work as a functional unit, with hK2 as the activator molecule and

We evaluated asthma control and medication use 5 years after introduction of an inhaled corticosteroid (budesonide via Turbuhaler(R)) in 462 patients with persistent asthma and symptoms of different duration. An early treatment group with symptoms for <2 years (group A) was compared with a delayed treatment group (group B) (median duration 5 years and 3 months). Most patients received budesonide 4
