Molecular motor gliding motility assays based on myosin/actin or kinesin/microtubules are of interest for nanotechnology applications ranging from cargo-trafficking in lab-on-a-chip devices to novel biocomputation strategies. Prototype systems are typically monitored by expensive and bulky fluorescence microscopy systems. The development of integrated, direct electric detection of single filaments
Objective: The purpose of this study was to clarify the mediational pathways from genetic risk for alcohol use disorder (AUD) to AUD itself. Method: Using information on AUD status from first-through fourth-degree relatives obtained from national registries, we created a genetic risk score for AUD for the Swedish population. We first tested a simple mediational path model in males and females sepa
Aim: We aimed to estimate the risk of hearing impairment in children and adolescents with foreign-born parents, compared to natives. Methods: A nationwide study of 1,923,590 (51.4% boys) individuals aged 0–17 years of age in Sweden. Hearing impairment was defined as at least one registered diagnosis in the National Patient Register between 1 January 1998 and 31 December 2015. We used Cox regressio
The genetic background of lupus nephritis (LN) has not been completely elucidated. We performed a case-only study of 2886 SLE patients, including 947 (33%) with LN. Renal biopsies were available from 396 patients. The discovery cohort (Sweden, n = 1091) and replication cohort 1 (US, n = 962) were genotyped on the Immunochip and replication cohort 2 (Denmark/Norway, n = 833) on a custom array. Pati
Both inflammatory proteins and microRNAs (miRNA) have been reported to be associated with various psychiatric disorders. However, the association between inflammatory proteins and miRNAs remains largely unknown, especially for patients with depression, anxiety, or stress- and adjustment disorders. In this study, we analyzed plasma levels of 92 inflammatory proteins from 178 patients with depressio
Exposure to phthalates is widespread and especially early life stages represent a critical window of exposure. In the present study, we investigated the effect of prenatal exposure to phthalates on birth outcomes and weight development in early life. In 130 mother–child pairs, we estimated the association of concentrations of 13 phthalates in spot-urine samples collected during pregnancy and birth
We report an efficient process for the oxidation of benzyl alcohols using molecular oxygen as the oxidant catalyzed by Ag-Cu catalysts supported on polyoxometalates (Ag-Cu/POM). The Ag-Cu/POM catalyst was prepared by galvanic displacement in the presence of polyvinyl pyrrolidone and polyethylene glycol. The catalysts were characterized using Fourier transform infrared spectroscopy (FTIR), ultravio
Persistent organic pollutants (POPs) are industrial chemicals with long half-lives. Early life exposure to POPs has been associated with adverse effects. Fetal exposure is typically estimated based on concentrations in maternal serum or placenta and little is known on the actual fetal exposure. We measured the concentrations of nine organochlorine pesticides (OCPs), ten polychlorinated biphenyl (P
Background and aim: Having a family member with an alcohol use disorder (AUD) may negatively affect a person's health. Our aim was to study the long-term risk of coronary heart disease (CHD) in parents who have an offspring with AUD. Design: Cohort study with Cox regression models and co-sibling analyses. Setting: Sweden. Participants: From population registers, we selected all parent-offspring pa
Performing fundamental operando catalysis studies under realistic conditions is a key to further develop and increase the efficiency of industrial catalysts. Operando X-ray photoelectron spectroscopy (XPS) experiments have been limited to pressures, and the relevance for industrial applications has been questioned. Herein, we report on the CO oxidation experiment on Pd(100) performed at a total pr
Background: Exposure to polycyclic aromatic hydrocarbons (PAHs) has been linked to adverse pulmonary effects. However, the impact of low-level environmental PAH exposure on lung function in early adulthood remains uncertain. Objectives: To evaluate the associations between urinary PAH metabolites and lung function parameters in young adults. Methods: Urinary metabolites of pyrene, phenanthrene, an
Although some neighborhood environmental factors have been found to affect depressive symptoms, few studies have focused on the impact of living in a hilly environment, i.e., land slope, on depressive symptoms among rural older adults. This cross-sectional study aimed to investigate whether a land slope is associated with depressive symptoms among older adults living in rural areas. Data were coll
We aimed (i) to gain a better understanding of the demographic and socioeconomical distribution of ADHD risk in Sweden; and (ii) to contribute to the critical discussion on medicalization, i.e., the tendency to define and treat behavioural and social problems as medical entities. For this purpose, we analysed the risk of suffering from ADHD in the whole Swedish population aged between 5 and 60 yea
Background We need to better understand the frequency and predictors of opioid use disorder (OUD) after first opioid prescription (OP). Methods We followed 1 516 392 individuals from the Swedish population born 1980-2000, from 1 July 2007, until 31 Dec 2017. We examined putative risk predictors with univariable and multivariable Cox Models and the potential causal effects of predictors by propensi
Background: Hypertension is the leading risk factor for cerebral small vessel disease. We aimed to determine whether antihypertensive drug classes differentially affect microvascular function in people with small vessel disease. Methods: We did a multicentre, open-label, randomised crossover trial with blinded endpoint assessment at five specialist centres in Europe. We included participants aged
Background and Hypothesis: To clarify whether the familial liability to psychosis associated with bipolar disorder (BD) is nonspecific or has a greater effect on risk for psychosis in cases with prominent mood symptoms and/or a remitting course. Study Design: We examined, in 984 809 offspring raised in intact families in Sweden, born 1980-1996 and followed-up through 2018, by multivariable Cox pro
Adherence to antiretroviral therapy is a global problem among adolescents living with human immunodeficiency viruses (HIV), and it is associated with treatment failure and the development of viral resistance. One of the most significant barriers to treatment adherence among adolescents is forgetting to take drugs as prescribed. One of the key strategies recommended to improve this problem is the u
Background. To determine whether genetic risk factors for major depression (MD) and alcohol use disorder (AUD) interact with a potent stressor – death of spouse, parent, and sibling – in predicting episodes of, respectively, MD and AUD. Methods. MD and AUD registrations were assessed from national Swedish registries. In individuals born in Sweden 1960–1970, we identified 7586, 388 459, and 34 370
Background: Older adults have complex medical needs that causes increased use of resources at the emergency department (ED). The prevalence of non-specific complaint (NSC) as a chief-complaint in the ED is common among older adults and is not prioritized even though possibly having worse clinical outcome. The objective was to study hospital admission and mortality for older adults visiting the ED
