The formation age of the large (∼50 km) Carswell impact structure, Canada, has been a matter of debate ever since its discovery five decades ago, with proposed ages ranging from Mesoproterozoic to Early Cretaceous. Here, we present new 40Ar-39Ar data for aliquots of euhedral adularia, separated from vesicles in an impact melt rock from the central uplift of the structure. The analyses of the adula
Objective: IgG antibodies against apolipoprotein A-I (ApoA-I) have been found to be elevated in subjects from the general population with clinically manifest cardiovascular disease and in myocardial infarction patients with an adverse prognosis. Here, we investigated whether these antibodies are prospectively associated with carotid artery disease progression and with the risk for first-time cardi
Intraischemic moderate hypothermia generally protects the brain against ischemic cell death, while hypothermia instigated several hours into the reperfusion phase is considered to be less effective. Here we report the effect of hypothermia (32.5°-33.5°C) of 5-h duration, initiated at 2, 6, 12, 24 and 36 h into the recirculation phase following 10 min of transient cerebral ischemia, on ischemic neu
While general trends in Central European postglacial recolonisation dynamics are relatively well known, we often lack studies on intermediate (meta-population, landscape) scales. Such studies are needed to increase our understanding of, for example, the location of refugia; emergence of endemism, rates and trajectories of postglacial migrations; and anthropogenic landscape changes. Here, we focuse
We use Monte Carlo simulations of a coarse-grained model to investigate structure and electrochemical behaviours at an electrode immersed in room temperature ionic liquids (RTILs). The simple RTIL model, which we denote the asymmetric restricted primitive model (ARPM), is composed of monovalent hard-sphere ions, all of the same size, in which the charge is asymmetrically placed. Not only the hard-
Interim medication-only treatment has been suggested for the initiation of opioid maintenance treatment (OMT) in opioid-dependent subjects, but this rarely has been studied using buprenorphine instead of methadone. Following a pilot trial assessing interim buprenorphine-naloxone treatment in order to facilitate transfer into OMT, we here aimed to study retention, and potential correlates of retent
Popular Abstract in Swedish SAMMANFATTNING PÅ SVENSKA (Swedish summary) Ultraljud används sedan 1970-talet rutinmässigt under graviditet. Undersökningen görs vanligen vid 17-18 graviditetsveckor och syftet med undersökningen är att datera graviditeten dvs bestämma tiden för beräknad förlossning. Man upptäcker också eventuella tvillingar vid denna undersökning. Redan tidigt visade det sig att visWe studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. We studied the effect of prenatal diagnosis on the rate of spina bifida in southern Sweden compared with the rest of the country and could show tha
OBJECTIVE: This article, based on the Early Manifest Glaucoma Trial (EMGT), provides prospective natural history data on progression of glaucomatous field defects in 3 of the most common glaucoma types. DESIGN: Cohort of EMGT patients randomized to the untreated control group and followed up to the time of progression, when treatment could be initiated. PARTICIPANTS: We evaluated 118 control patie
Previous studies have identified a range of transcription factors that modulate retrograde regulation of mitochondrial and chloroplast functions in Arabidopsis (Arabidopsis thaliana). However, the relative importance of these regulators and whether they act downstream of separate or overlapping signaling cascades is still unclear. Here, we demonstrate that multiple stress-related signaling pathway
In optical DNA mapping technologies sequence-specific intensity variations (DNA barcodes) along stretched and stained DNA molecules are produced. These "fingerprints" of the underlying DNA sequence have a resolution of the order one kilobasepairs and the stretching of the DNA molecules are performed by surface adsorption or nano-channel setups. A postprocessing challenge for nano-channel based met
Background: Serotonin (5-HT) is considered to play a role in pulmonary arterial hypertension by regulating vascular remodeling and smooth muscle contractility. Here, arteries from mice with inducible and smooth muscle-specific deletion of Dicer were used to address mechanisms by which microRNAs control 5-HT-induced contraction. Methods: Mice were used 5 weeks after Dicer deletion, and pulmonary ar

Om ungdomar mellan 15 och 20 – finns en skånsk modell Unga vuxna inför arbetsinträdet – finns en skånsk modell? Inledning Under senare år har uppmärksamhet riktats mot unga vuxnas situation inför arbetsmarknadsinträdet. Ett uttryck för detta var skärpningen år 2005 av det kommunala uppföljningsansvaret avseende tonåringar som inte gick i skola och inte hade någon känd sysselsättning. I samband med

Objectives: To examine potential sex differences in longitudinal cognitive and activities of daily living (ADL) performance and life expectancy between early- and late-onset Alzheimer’s disease (AD). Methods: The Swedish Alzheimer Treatment Study is a prospective, observational, multicentre study that was used in a routine clinical setting including 1,017 patients diagnosed with mild-to-moderate A
Many conservative public figures have claimed that Google Search exhibits a liberal bias in the links presented. Surprisingly, perhaps, the few scientific studies conducted so far have tended to support this claim. In the study reported here, we compared Google search engine result pages (SERPs) for 8 terms related to immigration across 8 geographically distinct locations (municipalities). For eac
Understanding the initial oxidation pathways on binary Ni-Cr surfaces is import for alloy development and rational design. The early-stage oxidation of Ni-22wt% Cr is studied in-situ and in-operando with synchrotron-based x-ray photoelectron microscopy (XPEEM) and x-ray photoelectron spectroscopy (XPS) at 500 °C and oxygen exposure from 0 to 65 Langmuir. Preferential Cr oxidation is accompanied by
Metastatic breast cancer (MBC) is generally considered an incurable disease and even though new treatments are available, the median survival is approximately three years. The introduction of immune therapies for MBC highlights the importance of the immune system in cancer progression and treatment. CD163+ anti-inflammatory myeloid cells, including tumor associated macrophages (TAMs), are known to
