Over the past 50 years, nutrient discharge into freshwater ecosystems has significantly increased due to intensive fertilizer application in China. This has led to frequent environmental issues associated with nutrient enrichment, such as algal blooms, in a number of individual lakes. However, the linkages between terrestrial nutrient sources and algal bloom occurrence (BO) at large scales remains
This study presents a cryogenic resonant radio frequency (RF) transmitter coil design for magnetic field generation that utilizes electromechanical switches to match and tune the resonance frequency with capacitor banks in situ. The design enables magnetic field generation at any frequency across a wide frequency range of 25-140 MHz (560% tuning range) while operating at 1.5 K. Magnetic field gene
Genetic trade-offs - which occur when variants that are beneficial in some contexts of natural selection are harmful in others - can influence a wide range of evolutionary phenomena, from the maintenance of genetic variation to the evolution of aging and sex differences. An extensive body of evolutionary theory has focused on the consequences of such trade-offs, and recent analyses of Fisher's geo
Context. The formation and evolution of ultra-short-period (USP) rocky planets is poorly understood. However, it is widely thought that these planets could not have formed at their present-day close-in orbits, but instead migrated inwards through interactions with outer neighbours. Aims. We aim to confirm and characterise the USP Earth-sized validated planet K2-157 b (Porb = 8.8 h) and constrain t
Clandestine migration is not only a response to precarious living conditions but also driven by aspirations and desires for change that migrants carry into their journeys. Yet, far less is known about what becomes of these subjective driving forces once people reach their destinations and settle down. To address this gap, this study explores how Syrian parents who risked crossing the Mediterranean
BACKGROUND: Differences in cardiac sarcoidosis between racial groups remain understudied. Therefore, this study aims to explore race differences in patients with cardiac sarcoidosis. METHODS: We analyzed data from the Cardiac Sarcoidosis Consortium, an international registry including over 25 centers. The primary clinical outcome was a composite end point of all-cause mortality, left ventricular a
PURPOSE. Epithelial maturation is essential for the specificity and functionality of retinal pigment epithelial (RPE) cell models. This study investigates how different maturation conditions shape RPE characteristics and cellular complement biology in two commonly used in vitro models: ARPE-19 and induced pluripotent stem cell–derived RPE (iPSC-RPE). METHODS. ARPE-19 and iPSC-RPE cells were cultur
Background: Joint pain and chronic back pain are highly prevalent in the aging population and have a large impact on life quality. As the underlying mechanisms are not fully understood, this exploratory cross-sectional study aimed to discover proteins and pathways associated with these two pain conditions in Swedish 70-year-old men. Methods: Plasma proteins (n = 720) were measured in participants
Formation and subsequent burial of authigenic phases have been recognized as a key process removing silicon from the ocean. However, the effect of authigenic phase formation on the isotopic mass balance of silicon in the ocean is not clear. Here, we constrain the apparent silicon isotope (δ30Si) fractionation associated with early diagenesis by measuring δ30Si signatures of pore fluids and authige
Roundtable presentation for: The Orient There and Back Again. Multidisciplinary Reflections on MENA Research and Sweden 1974-2024 (roundtable organised by Annika Rabo). Chair: Rouzbeh Parsi (Swedish Institute of International Affairs)Participants: Marianne Boqvist (Folke Bernadotte Academy), Torsten Janson (Lund University), Pernilla Myrne (University of Gothenburg), Annika Rabo (Stockholm Univers
Baobab (Adansonia digitata) seeds are a source of valuable lipids with notable nutritional and functional attributes. In response to the rising demand for sustainable, high-quality oils in the cosmetic and nutraceutical sectors, there is an increasing interest in environmentally friendly extraction techniques that maintain lipid bioactivity while reducing the use of toxic solvents. This study repr
Analyzing the behavior of birds offers insight into the conservation of biodiversity, a heavily discussed subject in the fields of ecology as well as ornithology. As it has been previously proven (Rushton et al., 1994), slow-flowing areas of rivers represent important habitats for birds all throughout the year and the conservation of this type of habitats has been known to have a positive effect o
Aims This study aimed to test whether seismocardiography (SCG) can detect changes in loading conditions and detect significant differences in SCG signals between healthy individuals and those with cardiovascular disease (CVD). Methods Twenty-six subjects (age 45 ± 16 years and 77% male) were included, 11 healthy subjects and 15 subjects with CVD. SCG and results was compared with transthoracic ech
Background This study aimed to describe the incidence rate, patient characteristics, treatments, and outcomes of adults hospitalized with Mycoplasma pneumoniae pneumonia. Methods This retrospective cohort study included adults diagnosed with M pneumoniae pneumonia and admitted to emergency care hospitals in Stockholm County, Sweden, from 2013 to 2017. Patients were identified through positive M pn
The increased demand, driven by a growing population and changing dietary habits, has created immense pressure on agroecosystems throughout the globe. In semi-arid areas, this increased pressure has led to excessive use of agrochemicals in agriculture, which poses a threat of potentially toxic metal (PTM) contamination in agricultural soils. PTMs in agricultural soils result in significant environ
Objective: Evaluate the impact of adrenalectomy on metabolic parameters and quality of life (QoL) in patients with mild autonomous cortisol secretion (MACS). Method: A multicenter prospective randomized clinical trial compared adrenalectomy with conservative management. Metabolic parameters and QoL were assessed at baseline and after 2 years. Results: Forty-three MACS patients with a single adrena
