Bread dough was studied in relation to three Andean grain flours, quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and canahua (Chenopodium pallidicaule), as partial replacements for wheat flour with the perspectives of dough and breadmaking. This thesis deals with the understanding of both dough as a complex system, consisting of various water-filled polymers, and dough as a viscoelast
Alzheimer's disease researchers have been intrigued by the selective regional vulnerability of the brain to amyloid-β plaques and tau neurofibrillary tangles. Post-mortem studies indicate that in ageing and Alzheimer's disease tau tangles deposit early in the transentorhinal cortex, a region located in the anterior-temporal lobe that is critical for object memory. In contrast, amyloid-β pathology
In order to identify the signal epitopes of the neuropeptide Y (NPY) molecule, the conformation of the NPY molecule was pertubated by a systematic double D-amino acid replacement of neighbouring residues. These NPY-analogs were examined for receptor affinity and on biological activity. The rat cerebral cortex and hippocampus were used for binding characteristics on Y1 and Y2 binding sites, respect
Colorectal cancer (CRC) is the third most common cancer worldwide. Increasing evidence suggests that CRC should be considered a heterogeneous disease, with multiple differences between proximal and distal tumours. The immune system may, depending on the context, promote or inhibit tumour growth, and different immune cell subsets have been found to be associated with impaired or improved prognosis
Abstract Noroviruses are now the leading cause of gastroenteritis worldwide. Noroviruses are effectively transmitted due to a low infectious dose, viral shedding in high concentrations, environmental stability, and they induce only a limited immunity after infection. Especially, the norovirus variants of genotype II.4 (GII.4) have seemed greatly adapted for pandemic spread. The high infectivity o
The incidence of narcolepsy type 1 (NT1) increased in Sweden following the 2009-2010 mass-vaccination with the influenza Pandemrix-vaccine. NT1 has been associated with Human leukocyte antigen (HLA) DQB1*06:02 but full high-resolution HLA-typing of all loci in vaccine-induced NT1 remains to be done. Therefore, here we performed HLA typing by sequencing HLA-DRB3, DRB4, DRB5, DRB1, DQA1, DQB1, DPA1
Background: Screening that includes digital breast tomosynthesis (DBT) with two-dimensional (2D) synthetic mammography (SM) or standard 2D digital mammography (DM) results in detection of more breast cancers than does screening with DM alone. A decrease in interval breast cancer rates is anticipated but is not reported. Purpose: To compare rates and characteristics of (a) interval breast cancer in
Malignant melanoma is a heterogeneous, malignant neoplastic disease, most often originating in the skin. Melanoma is characterized by a high mutational load and has a vastly variable prognosis, depending on disease stage. Genetic aberrations in the mitogen-activating protein kinase (MAPK) pathway are important in melanoma, of which mutations in BRAF and NRAS are the most common. Additionally, recu
Background: The prognosis of Alzheimer’s disease (AD) might be influenced by many sociodemographic and clinical factors. Previous studies have investigated the main effects of critical predictors but few have analyzed potential interactions. We have studied the long-term cognitive outcome, nursing home placement (NHP) and mortality by interactions between factors in cholinesterase inhibitor (ChEI)
Background: Male breast cancer (BC) is rare, managed by extrapolation from female BC. The International Male BC Program aims to better characterize and manage this disease. We report the results of part I, a retrospective joint analysis of cases diagnosed during a 20-year period. Methods: Patients with follow-up and tumor samples, treated between 1990 and 2010, in 93 centers/9 countries. Samples w
Genetic factors play an important role in the pathogenesis of osteoporosis but the genes that determine susceptibility to poor bone health are defined incompletely. Previous work has shown that a polymorphism that affects an Spl binding site in the COLIA1 gene is associated with reduced bone mineral density (BMD) and an increased risk of osteoporotic fracture in several populations. Data from cros
Objective: To determine the role of inflammatory biomarkers at 2 years post–anterior cruciate ligament (ACL) injury to predict radiographic knee osteoarthritis (OA) and magnetic resonance imaging (MRI)–defined knee OA at 5 years postinjury, with a secondary aim of estimating the concordance of inflammatory biomarkers assessed by MRI and synovial fluid (SF) analysis. Methods: We studied 113 patient
Background: Ovarian tumours are usually surgically removed because of the presumed risk of complications. Few large prospective studies on long-term follow-up of adnexal masses exist. We aimed to estimate the cumulative incidence of cyst complications and malignancy during the first 2 years of follow-up after adnexal masses have been classified as benign by use of ultrasonography. Methods: In the
BACKGROUND: Sacroiliac joint pain is increasingly recognized as a cause of low back pain. We compared the safety and effectiveness of minimally invasive sacroiliac joint arthrodesis using triangular titanium implants and conservative management in patients with chronic sacroiliac joint pain. METHODS: This study was a prospective, multicenter randomized controlled trial of adults with chronic sacro
BACKGROUND: Breast cancer in young adults has been implicated with a worse outcome. Analyses of genomic traits associated with age have been heterogenous, likely because of an incomplete accounting for underlying molecular subtypes. We aimed to resolve whether triple-negative breast cancer (TNBC) in younger versus older patients represent similar or different molecular diseases in the context of g
Importance: Circulating levels of neurofilament light (NfL) and glial fibrillary acidic protein (GFAP) are important in the course of brain injury in adults, but longitudinal postnatal circulating levels in preterm infants have not been investigated. Objectives: To examine postnatal longitudinal serum levels of NfL and GFAP in preterm infants during the first 15 weeks of life and to explore possib
Background: The mechanisms underlying the obesity-cancer relationship are incompletely understood. This study aimed to characterise metabolic signatures of greater body size and to investigate their association with two obesity-related malignancies, endometrial and colorectal cancers, and with weight loss within the context of an intervention study. Methods: Targeted mass spectrometry metabolomics
Objective: To compare the real-life effectiveness of biologic therapy (a biologic disease-modifying antirheumatic drug plus methotrexate [MTX]) versus triple therapy (MTX plus sulfasalazine plus hydroxychloroquine/chloroquine) for sustained remission of rheumatoid arthritis (RA). Methods: RA patients who were registered in the nationwide Swedish Rheumatology Quality Register between 2000 and 2012
Objective: To investigate the causal role of cardiometabolic risk factors in osteoarthritis (OA) using associated genetic variants. Methods: We studied 27,691 adults from the Malmö Diet and Cancer Study (MDCS) and replicated novel findings among 376,435 adults from the UK Biobank. Trait-specific polygenic risk scores for low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol
