Amyloid-β (Aβ) pathology is one of the earliest detectable brain changes in Alzheimer’s disease (AD) pathogenesis. The overall load and spatial distribution of brain Aβ can be determined in vivo using positron emission tomography (PET), for which three fluorine-18 labelled radiotracers have been approved for clinical use. In clinical practice, trained readers will categorise scans as either Aβ pos
Maternal smoking during pregnancy constitutes a potential, major risk factor for adult male reproductive function. In the hitherto largest longitudinal cohort, we examined biomarkers of reproductive function according to maternal smoking during the first trimester and investigated whether associations were mitigated by smoking cessation prior to the fetal masculinization programming window. Associ
An increasing number of litigations before the International Court of Justice (ICJ) concerns situations involving serious crimes (genocide, crimes against humanity and war crimes). However, to date, several of these litigations have failed to deliver justice in the form of reparations to the victims of these crimes. Two recurrent legal obstacles impede effective results: the limits imposed on this
A comprehensive understanding of local HIV epidemiology is essential for monitoring transmission, designing, implementing, and evaluating HIV intervention strategies. In paper I, we used a total of 1276 HIV-1 subtype C pol sequences and employed state-of-art phylogenetic and phylodynamic tools to describe the molecular epidemiology of HIV in Ethiopia. Our results showed that the HIV epidemic in E
Spectrum clustering is a powerful strategy to minimize redundant mass spectra by grouping them based on similarity, with the aim of forming groups of mass spectra from the same repeatedly measured analytes. Each such group of near-identical spectra can be represented by its so-called consensus spectrum for downstream processing. Although several algorithms for spectrum clustering have been adequat
Streptococcus pneumoniae (pneumococcus) is an asymptomatic colonizer of the nasopharynx in most individuals but can progress to a pulmonary and systemic pathogen upon influenza A virus (IAV) infection. Advanced age enhances host susceptibility to secondary pneumococcal pneumonia and is associated with worsened disease outcomes. The host factors driving those processes are not well defined, in part
Purpose: To examine [18F]RO948 retention in FTD, sampling the underlying protein pathology heterogeneity. Methods: A total of 61 individuals with FTD (n = 35), matched cases of AD (n = 13) and Aβ-negative cognitively unimpaired individuals (n = 13) underwent [18F]RO948PET and MRI. FTD included 21 behavioral variant FTD (bvFTD) cases, 11 symptomatic C9orf72 mutation carriers, one patient with non-g
Benchmarking has been a useful tool for unbiased comparison of control strategies in wastewater treatment plants (WWTPs) in terms of effluent quality, operational cost and risk of suffering microbiology-related total suspended solids (TSS) separation problems. This chapter presents the status of extending the original Benchmark Simulation Model No 2 (BSM2) towards including greenhouse gas (GHG) em
The Cherenkov Telescope Array (CTA) is the next-generation gamma-ray observatory currently under construction. It will improve over the current generation of imaging atmospheric Cherenkov telescopes (IACTs) by a factor of five to ten in sensitivity and it will be able to observe the whole sky from a combination of two sites: a northern site in La Palma, Spain, and a southern one in Paranal, Chile.
Background: Most studies on long-term follow-up of patients with COVID-19 focused on hospitalised patients. No prospective study with structured follow-up has been performed in non-hospitalised patients with COVID-19. Objectives: To assess long-COVID and post-COVID (WHO definition: symptomatic at least 12 weeks), describe lingering symptoms, their impact on daily activities, and general practice v
Background: Neurological injuries are frequent following Acute Type A Aortic Dissection (ATAAD) repair occurring in 4–30% of all patients. Our objective was to study whether S100B can predict neurological injury following ATAAD repair. Methods: This was a single-center, retrospective, observational study. The study included all patients that underwent ATAAD repair at our institution between Jan 19
Interstitial lung diseases such as idiopathic pulmonary fibrosis (IPF) are caused by persistent micro-injuries to alveolar epithelial tissues accompanied by aberrant repair processes. IPF is currently treated with pirfenidone and nintedanib, compounds which slow the rate of disease progression but fail to target underlying pathophysiological mechanisms. The DNA repair protein 8-oxoguanine DNA glyc
We present the concept of our new high power laser facility Attohallen in Gothenburg, with focus on its first high-order harmonic generation beam line. The key specifications of this facility, including the architecture and operation of the femtosecond drive laser system, the XUV generation part of its first beam line for photon-demanding attosecond timing experiments in the energy range up to abo
Heat stress events will be more frequent and intense in the future. These events will challenge the capacity of organisms to exhibit sufficient metabolic flexibility to adapt to such variations. To better understand the acclimation processes implemented in response to acute warming, with an integrative approach we examined in vivo metabolic rate and cardiac mitochondrial respiration in the Rhône s
Wetlands play a critical role in the global water cycle and ecological health. However, understanding and accurately parameterizing water and heat exchanges in these areas is challenging due to the heterogeneous nature of wetland surfaces. This study extends the maximum entropy production (MEP) model to simulate wetland evapotranspiration (ET) by integrating NDVI dynamics, water evaporation, and p
Pixel sensors in 3D technology equip the outer ends of the staves of the Insertable B Layer (IBL), the innermost layer of the ATLAS Pixel Detector, which was installed before the start of LHC Run 2 in 2015. 3D pixel sensors are expected to exhibit more tolerance to radiation damage and are the technology of choice for the innermost layer in the ATLAS tracker upgrade for the HL-LHC programme. While
Background and objective: The European Association of Urology (EAU) renal cell carcinoma (RCC) guideline panel has updated their evidence-based guidelines and recommendations for the management of RCC. Here we present a summary of the 2025 RCC guidelines updated with standardised methodology to provide reproducible evidence for the management of RCC. Methods: For the 2025 update, a literature sear
A Lagrangian approach has been used to assess the degree of chemically induced ozone loss in the Arctic lower stratosphere in winter 1991/1992. Trajectory calculations are used to identify air parcels probed by two ozonesondes at different points along the trajectories. A statistical analysis of the measured differences in ozone mixing ratio and the time the air parcel spent in sunlight between th
The green transition relies on metals, requiring increased metal recovery from waste. However, exposure risks among metal recycling workers are poorly understood. We conducted a cross-sectional study to assess dust and metal exposure among 139 recycling workers from 13 Swedish metal recycling companies and 90 controls. We documented work practices through observations and questionnaires and assess
Objectives To investigate sex education in Swedish schools regarding content, satisfaction, and suggested improvements, as described by teenagers and young adults. Methods Waiting-room survey conducted among 225 female patients (aged 13-25) at youth and student health clinics in one large-, and one medium-sized Swedish city. Results Most participants (97%, n=218) had received sex education in scho
