Ageing in the human brain is a major risk factor for most neurodegenerative diseases. Yet the cell-type-specific molecular changes that contribute to this risk remain poorly understood. This thesis investigates cell-type-specific changes across multiple levels of molecular regulation and their roles in physiological and pathophysiological brain ageing. Using single-nucleus RNA sequencing of postmo
Several factors contribute to the use, non-use, or inadequate use of personal protective equipment (PPE) in construction work. This study aimed to analyse correct usage of various PPE, such as helmet, ear protectors, goggles, respiratory mask, gloves, protective clothing, and a safety harness. Correct usage was assessed as guessability, which refers to human perceptions of how to don, adjust, use,
Background: – Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is rare in children, and results in kidney failure in up to one third of cases. There is very limited knowledge on kidney transplantation in childhood-onset AAV. We assessed kidney transplantation outcomes and prognostic factors in a multicentre cohort of patients with childhood-onset AAV.Methods: – Patients diag
In recent years, the automotive industry has increasingly prioritized comfort to meet rising consumer expectations for luxurious car experiences. Comfort, a subjective concept associated with well-being and relaxation, encompasses multidimensional aspects rooted in physical, psychological, and functional aspects. While existing comfort models focus mainly on seated positions and sensations like fa
The energy system is undergoing significant changes and is expected to continue to evolve. Energy demand is anticipated to increase, as is renewable energy capacity, and technical solutions are advancing. For electrical power, traditionally centralized production is increasingly complemented by distributed production, transforming fundamental system functionality. These developing factors will aff
Background: Severe Alpha-1-Antitrypsin deficiency (AATD), phenotype PiZZ, is a leading cause of liver disease in neonates, children, and adults. Nevertheless, the prevalence of liver disease and mortality within PiZZ adults remains unclear. Between 1972 and 1974, a cohort of 129 individuals with severe AATD (PiZZ) was identified through the Swedish national screening of 200,000 newborns. The cohor
Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors, including abdominal obesity, insulin resistance, dyslipidemia, and hypertension. Its association with venous thromboembolism (VTE) has been inconsistently reported. We investigated the association between MetS and VTE, and the influence of sex and abdominal obesity. We included 12,788 middle-aged and older adults from the re-ex
Questions: How did α-, β- and γ- plant diversity of coastal dune slack plant communities change over 37 years during a period of significant changes in conservation management practices?. Location: Ainsdale Sand Dunes National Nature Reserve, England. Methods: We surveyed plant communities in dune slacks at Ainsdale Sand Dunes National Nature Reserve at two time points: in 1985 and in 2022. This p
Low back pain is common and negatively impacts quality of life and workplace productivity. However, few studies have focused on small- and medium-sized enterprises (SMEs) where risk factors are prevalent. This cross-sectional study examined the association and structural relationships between physical and social factors in low back pain among Japanese SME workers. We analyzed survey data collected
Aims: To examine whether genetic variants that predispose individuals to type 2 diabetes (T2D) could predict the development of diabetes after gestational diabetes mellitus (GDM). Methods: 13 SNPs (FTO rs8050136, CDKAL1 rs7754840 and rs7756992, CDKN2A/2B rs10811661, HHEX rs1111875, IGF2BP2 rs1470579 and rs4402960, SLC30A8 rs13266634, TCF7L2 rs7903146, PPARG rs1801282, GCK rs1799884, HNF1A rs116928
Whether loci that influence fasting glucose (FG) and fasting insulin (FI) levels, as identified by genome-wide association studies, modify associations of diet with FG or FI is unknown. We utilized data from 15 US and European cohort studies comprising 51,289 persons without diabetes to test whether genotype and diet interact to influence FG or FI concentration. We constructed a diet score using s
The modified phonon dispersion is of importance for understanding the origin of the reduced heat conductivity in nanowires. We have measured the phonon dispersion for 50 nm diameter InSb (111) nanowires using time-resolved X-ray diffraction. By comparing the sound speed of the bulk (3880 m/s) and that of a classical thin rod (3600 m/s) to our measurement (2880 m/s), we conclude that the origin of
Background-Carotid intima-media thickness (cIMT) is a widely accepted marker of subclinical atherosclerosis. To date, large-scale investigations of genetic determinants of cIMT are sparse. Methods and Results-To identify cIMT-associated genes and genetic variants, a discovery analysis using the Illumina 200K CardioMetabochip was conducted in 3430 subjects with detailed ultrasonographic determinati
The aggregation of α-synuclein plays a major role in Parkinson disease (PD) pathogenesis. Recent evidence suggests that defects in the autophagy-mediated clearance of α-synuclein contribute to the progressive loss of nigral dopamine neurons. Using an in vivo model of α-synuclein toxicity, we show that the PD-like neurodegenerative changes induced by excess cellular levels of α-synuclein in nigral
BACKGROUND: Progressive immune dysfunction and the acquired immunodeficiency syndrome (AIDS) develop in most persons with untreated infection with human immunodeficiency virus type 1 (HIV-1) but in only approximately 20 to 30% of persons infected with HIV type 2 (HIV-2); among persons infected with both types, the natural history of disease progression is poorly understood. METHODS: We analyzed d
Low-frequency coding DNA sequence variants in the proprotein convertase subtilisin/kexin type 9 gene (PCSK9) lower plasma low-density lipoprotein cholesterol (LDL-C), protect against risk of coronary heart disease (CHD), and have prompted the development of a new class of therapeutics. It is uncertain whether the PCSK9 example represents a paradigm or an isolated exception. We used the "Exome Arra
Increased glucose levels are associated with the generation of advanced glycation endproduct (AGE) modifications. Interaction between AGE-modified plaque components and immune cells is believed to have an important role in the development of vascular complications in diabetes. Methylglyoxal (MGO) is one type of reactive aldehyde that gives rise to AGE modification. The present study analyzed wheth
OBJECTIVES: Prostate specific antigen (PSA) is a widely used and clinically valuable marker for prostate disease. In order to enable the development of new PSA assays and progress the understanding of the biology of PSA we have analyzed PSA in seminal plasma. Design and methods PSA in seminal plasma from men attending a fertility clinic and healthy controls was analyzed using SDS-PAGE, Western blo
OBJECTIVE: The brain derived neurotrophic factor (BDNF) locus has been implicated in psychiatric and substance related disorders. Recent genome-wide association studies (GWAS) have shown strong associations between single nucleotide polymorphisms in BDNF, smoking behaviour and high body mass index (BMI). Our aim was to test whether genetic BDNF variation alters the risk of smoking related morbidit
