Methanol can be produced renewably and used in compression ignition (CI) engines as a replacement for fossil diesel. However, methanol is a low cetane fuel, creating challenges in achieving stable operation, particularly at low load. One potential solution is through surface ignition via a glow plug. In this work, experiments were conducted on a methanol-fueled 2.1 L single cylinder engine instrum
Objective: To evaluate the causal effect of genetically predicted serum urate (SU) levels on the risk of overall and major site-specific cancers in individuals of European ancestry, using Mendelian randomization (MR) analysis. Method: Data from two population-based cohorts from southern Sweden, the Malmö Diet and Cancer Study (MDCS) and Malmö Preventive Project (MPP), and summary-statistics data f
We investigated integrative physiological responses to eupnoeic exercise (EX), rebreathing exercise (RB), dynamic apnoea (DA) and dynamic apnoea with cold-water face immersion (DAFI) in 20 healthy participants. Trials involved non-steady-state cycle exercise at 60 W for an average duration of 66 s. With increases in heart rate and stroke volume, EX and RB increased cardiac output compared with bas
Phosphatidylethanol (PEth) is a direct ethanol metabolite, and has recently attracted attention as biomarker of ethanol intake. The aims of the current study are: (1) to characterize the normalization time of PEth in larger samples than previously conducted; (2) to elucidate potential gender differences; and (3) to report the correlation of PEth with other biomarkers and self-reported alcohol cons
Herbivory is an important part of most ecosystems, and grazing alone can have a considerable impact on the ecosystems carbon balance with both direct and indirect effects. Removal of above-ground biomass by consumption of herbivores will change the below-ground carbon stock; the reduction of litter that goes into the ground will influence the total ecosystem carbon content. Little is however known
Background and aimMany patients with depressive disorders do not improve with first-line treatment with selective serotonin inhibitors (SSRIs). Adverse drug reactions (ADRs) are common. However, there are no reliable methods to predict treatment response.The general aim of this thesis was to investigate the role of peripheral serotonin and the polymorphic CYP2D6 gene as potential biomarkers of tre
Introduction: Suturing is a fundamental component of surgical procedures, wherein training emphasises the significance of gentle tissue handling. The suturing process involves the pressure exerted by the forceps onto the tissue, as well as the medial traction force applied to stabilise the tissue during the needle bite. This study examined the forces involved in tissue handling during suturing, co
Background: Alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) are frequently comorbid and are individually associated with increased risk of suicidal behavior. However, whether their comorbidity exacerbates this risk has not been adequately investigated. Methods: Using a Swedish birth cohort (born 1970–1990; N = 799,203–858,983), we employed Aalen’s linear hazards models to evalu
Background: Programmed death-ligand 1 (PD-L1) immunocytochemical (ICC) analysis of cell blocks (CBs) has recently emerged in clinical practice. Unlike standardized immunohistochemistry on formalin-fixed, paraffin-embedded tissues, cytology involves various preparation methods and fixatives. This study investigated how various fixatives influence PD-L1 immunoreactivity in CBs from malignant pleural
GOALS: To assess the incidence, type, and severity of infections in patients with IBD before and after starting thiopurine therapy.BACKGROUND: Thiopurines have been used for decades in the treatment of inflammatory bowel disease (IBD), yet real-world data regarding the extent and types of infections associated with their use are scarce.STUDY: We included all thiopurine-naive adults with IBD who in
Background: We aimed to assess the risk of serious infections in patients with inflammatory bowel disease (IBD) exposed to different advanced therapies. Methods: We linked nationwide registers and compared rates of incident serious infections in patients with Crohn’s disease (CD) and ulcerative colitis (UC) exposed to medical therapies versus matched general population comparators during 2007-2023
Introduction: Using time-limited trials of low-dose, sustained-release morphine to reduce chronic breathlessness to evaluate net effects may generate opioid withdrawal symptoms if medication is ceased. This sub-study of a larger randomized, placebo-controlled, double-blind trial aimed to evaluate if this occurred. Methods: People with modified Medical Research Council breathlessness scores of 3 or
Accurate, high-resolution global land use and land cover (LULC) mapping is crucial for environmental monitoring, but remains challenging when relying solely on multispectral data. Most existing global LULC mapping studies rely exclusively on multispectral observations, and even those that incorporate synthetic aperture radar (SAR) data often fail to fully exploit the information it provides. SAR p
Introduction Systemic inflammation is postulated to mediate heat stroke and heat-related organ injury, yet acute inflammatory responses among heat-stressed workers remains poorly understood. We aimed to describe neutrophil mobilisation and potential release of DNA during heat stress in multiple hot occupational settings and a controlled experimental setting. Methods Neutrophil:lymphocyte ratio (NL
Objectives: Panax ginseng (P. ginseng, C.A. Meyer) is suggested to improve blood glucose regulation, but evidence remains inconsistent. We examined whether consuming P. ginseng as a preload before a carbohydrate-rich meal modulates postprandial glucose and insulin responses. Methods: In a randomized, double-blind, crossover trial, 22 healthy middle-aged adults consumed P. ginseng tablets containin
BACKGROUND AND OBJECTIVE: Achieving adequate concentrations of beta-lactam antibiotics in patients with severe infections is challenging, and therefore therapeutic drug monitoring (TDM) would be optimal for guiding beta-lactam dosing, but is often limited by availability. UV/VIS spectrophotometry can quantify drug levels in saline, and if those levels truly reflect plasma concentrations, it could
BACKGROUND/AIM: Determining the causation of an injury in living individuals is a key task for forensic pathologists. However, little is known about sex-based differences in injury characteristics. The study aims to examine sex-based differences in single stab injuries to the trunk among assault survivors, to potentially identify injury patterns that could aid forensic assessment and help in the m
BACKGROUND: Early HIV diagnosis allows timely interventions to control HIV transmission. We have determined the proportion of recent infections among people living with HIV (PLHIV) enrolling to care in Ethiopia and identified factors associated with recent infection. METHODS: Participants (aged ≥ 15 years) newly enrolled in HIV care were recruited from urban clinics in central Ethiopia (2022-2024)
This review aimed to summarize and estimate the TB treatment success rate and factors associated with unsuccessful TB treatment outcomes in Africa. Potentially eligible primary studies were retrieved from PubMed and Google Scholar. The risk of bias and quality of studies was assessed using The Joanna Briggs Institute’s (JBI) appraisal criteria, while heterogeneity across studies was assessed using
BACKGROUND AND PURPOSE: Low serum potassium is associated with stroke in populations with cardiovascular disease, hypertension, and diabetes mellitus but has not been studied in a mainly healthy population. We aimed to study the relation between serum potassium and incident stroke and mortality in the Malmö Preventive Project, a large cohort with screening in early mid-life and follow-up >25 years
