Pollen and sediment stratigraphic analyses of a transect of core sequences are used to reconstruct Holocene lake-level changes in Lake Igelsjon, southern Sweden. The pattern of changes seen in the records is related to climatic/hydrological changes and agrees principally with the pattern characteristically found in lakes in southern Sweden. However, compared with an earlier study based on isotopic

Aortic stenosis (AS) shares risk factors with atherosclerotic vascular disease. Carotid intima-media thickness (IMT) and plaque may reflect the cumulative damage from exposure to different atherosclerotic risk factors. We examined the relationship of carotid IMT and plaque with incident AS in a prospective population-based study.

Color patterns play central roles in the behavior of insects, and are important traits for taxonomic studies. Here we report striking and stable structural color patterns—wing interference patterns (WIPs) —in the transparent wings of small Hymenoptera and Diptera, patterns that have been largely overlooked by biologists. These extremely thin wings reflect vivid color patterns caused by thin film i

Objectives: Rheumatoid arthritis (RA) is associated with cardiovascular disease (CVD). Possible predictors for CVD are early changes in body composition. We therefore evaluated changes in lean body mass (LBM), lean mass of arms and legs (LMAL), total body fat mass (BFM), and truncal fat distribution (FD) after 2 years with RA and possible predictors. Methods: We registered 63 (45 women) RA patient

PurposeA segmented inversion-recovery module combined with the 2D ultrashort echo time radial technique is proposed that allows accurate pixel level T-1 mapping of mouse lung in vivo. MethodsNumerical simulations were performed to estimate T-1 measurement accuracy and precision versus flip angle and signal-to-noise ratio. Phantom measurements were used for protocol validation, where the segmented

Abstract in UndeterminedWe introduce a new method for prestack depth migration of seismic common-shot gathers.The computational procedure follows standard steps of the reverse-time migration, i.e.,downward continuation of the `source' and the `receiver' waveelds, followed by applicationof an imaging condition (e.g. zero-lag cross-correlation of these elds). In our method werst nd a sparse data rep

Iran has the highest rate of road traffic accidents (RTAs) worldwide. Iranian studies of the growing levels of RTAs are often conducted by medical doctors, who view them in light of the increase in the production and ownership of cars and the changed lifestyle of many Iranians, and discuss them in terms of pathology, morbidity and epidemiology. This paper argues that although the high levels of RT

In Parkinson's disease (PD) progressive alteration of striatal N-methyl-D-aspartate receptors (NMDARs) signaling has emerged as a considerable factor for the onset of the adverse motor effects of long-term levodopa (L-DOPA) treatment. In this regard, the NMDAR channel blocker amantadine is so far the only drug available for clinical use that attenuates L-DOPA-induced dyskinesia (LID). In this stud

Human stability control is a complex process comprising contributions from several partly independent mechanisms such as coordination, feedback and feed-forward control, and adaptation. Acute alcohol intoxication impairs these functions and is recognized as a major contributor to fall traumas. The study aimed to investigate how alcohol intoxication at .06% and .10% blood alcohol concentration (BAC

Aging of the hematopoietic stem cell compartment is believed to contribute to the onset of a variety of age-dependent blood cell pathophysiologies. Mechanistic drivers of hematopoietic stem cell (HSC) aging include DNA damage accumulation and induction of tumor suppressor pathways that combine to reduce the regenerative capacity of aged HSCs. Such mechanisms do not however account for the change i

The northern terrestrial net ecosystem carbon balance (NECB) is contingent on inputs from vegetation gross primary productivity (GPP) to offset the ecosystem respiration (R-eco) of carbon dioxide (CO2) and methane (CH4) emissions, but an effective framework to monitor the regional Arctic NECB is lacking. We modified a terrestrial carbon flux (TCF) model developed for satellite remote sensing appli

This paper discusses a number of questions with regard to Sweden’s economic and political development: † How did Sweden become rich? † What explains Sweden’s high level of income equality? † What were the causes of Sweden’s problems from 1970 to 1995? † How is it possible that Sweden, since the crisis of the early 1990s, is growing faster than most EU countries despite its high taxes and generous

Background. Autism spectrum disorder (ASD) is a neurodevelopmental disorder of complex etiology. Although strong evidence supports the causal role of genetic factors, environmental risk factors have also been implicated. This study used a co-twin-control design to investigate low birth weight as a risk factor for ASD. Method. We studied a population-based sample of 3715 same-sex twin pairs partici

The composition of milk fat from dairy cows is related to both genetic and environmental factors. Here, the effect of feed and herd was examined in 3 Scandinavian breeds, namely Danish Holstein-Friesian (DH), Danish Jersey (DJ), and Swedish Red (SR). In total, milk samples from 1,298 cows kept in indoor housing systems were collected from 61 conventional dairy herds in Denmark and Sweden. The fatt

Diabetes mellitus is the main reason for visual impairment among patients of working ages. The aim of this paper was to investigate the prognosis of eye complications in patients with diabetes during 10 years of follow-up and contributing risk factors. Data from ophthalmological records (occurrence of retinopathy and laser treatment and visual acuity), and clinical data (blood pressure, glycosylat

The objective was to estimate the cost-effectiveness of TNF-inhibitors for the treatment of rheumatoid arthritis in Swedish clinical practice, both as a first and second biological treatment, with or without the combination of conventional DMARDs. Further sub-group analysis of etanercept treatment was performed. Patient level data were obtained from three regions of the Swedish Rheumatology Regist

Parents influence adolescent drinking behavior, but to what extent does this association diminish with age, however? The cross-sectional data was drawn from the Scania drug use survey 2007, consisting of 4,828 secondary education students in the 9th and 11th grade. The age- and gender-adjusted findings indicate that having parents who are consenting to alcohol use (OR 1.4), having been provided wi

It has been suggested that time selection and precedence in arrival order are more important during spring than autumn migration. Migrating birds are expected to fly at faster airspeeds if they minimize duration rather than energy costs of migration, and they are furthermore expected to complete their journeys by final sprint flights if it is particularly important to arrive at the destination bef

Autoimmune responses against oxidized-LDL (oxLDL) have been suggested to modulate inflammation in atherosclerosis. Previous studies showed an association between autoantibodies against the apolipoprotein B (apoB) p210 antigen and a lower risk of cardiovascular (CV) events. In the present study we investigated if autoantibodies against p210 at the time of carotid endarterectomy (CEA) predict risk f

The radionuclide (210)Po is of importance from a radiation protection view and has properties that cause special problems when attempting to determine the body content in humans. Estimates have traditionally been made from either urine and/or fecal samples, which require a time-consuming radiochemical preparation before alpha spectrometric determination. In order to find a more simple and less lab
