BackgroundSelenoprotein P (SELENOP) is a transporter for selenium and has been shown to protect selenium status maintenance in brain against deficiency, supporting neuronal development, neurogenesis and neurocognitive function. Selenium deficiency has previously been associated with cognitive impairment in various populations, but no studies have been carried out in subjects with heart failure (HF

Mid-infrared polarization spectroscopy was applied to detect HCl at trace level in an atmospheric pressure premixed H2/O2/Ar flame with chloroform seeding. Detection sensitivity and potential interference from water lines was investigated.

Background: Neuropsychiatric symptoms (NPS) are common in individuals with Alzheimer’s disease (AD) dementia, but substantial heterogeneity exists in the manifestation of NPS. Sex differences may explain this clinical variability. We aimed to investigate the sex differences in the prevalence and severity of NPS in AD dementia. Methods: Literature searches were conducted in Embase, MEDLINE/PubMed,

The urbanization of landscapes and the increase in impervious land cover materials is known to cause significant changes in the landscape's thermal properties, typically leading to urban heat island (UHI). Although previous studies have investigated the impacts of land cover land use (LULC) and other factors on the urban land surface temperature (LST), the results of such studies are mixed. For in

Background: Depression is a risk factor for type 2 diabetes (T2D) and cardiovascular disease (CVD). The aims were to explore the prevalence of depression, anxiety, antidepressant use, obesity, Hemoglobin A1c > 64 mmol/mol, life-style factors, pre-existing CVD, in patients with newly diagnosed T2D; to explore associations with depression; and to compare with Swedish general population data. Methods

Objectives: The aim of this study was to investigate genetic outcomes, analyze the family experience, and describe the process of implementing genetic sequencing for children with profound sensorineural hearing loss (SNHL) at a tertial audiological center in southern Sweden. Design: This is a prospective pilot study including eleven children with profound bilateral SNHL who underwent cochlear impl

Background: Hepatitis B virus infection is a global health problem with the highest prevalence in East Asia and Sub-Saharan Africa. The majority of infected people, including healthcare workers are unaware of their status. This study is aimed to determining seroprevalence of hepatitis B virus infection and associated factors among healthcare workers in northern Tanzania. Methods: This cross-sectio

The structural heterogeneity of tumor tissue can be probed by diffusion MRI (dMRI) in terms of the variance of apparent diffusivities within a voxel. However, the link between the diffusional variance and the tissue heterogeneity is not well-established. To investigate this link we test the hypothesis that diffusional variance, caused by microscopic anisotropy and isotropic heterogeneity, is assoc

IMPORTANCE Fluid overload occurring as a consequence of overly aggressive fluid resuscitation may adversely affect outcome in hemodynamically unstable critically ill patients. Therefore, following the initial fluid resuscitation, it is important to identify which patients will benefit from further fluid administration. OBJECTIVE To identify predictors of fluid responsiveness in hemodynamically uns

Retinitis pigmentosa is a group of inherited retinal degenerative diseases characterized by the loss of photoreceptors and vision for which no effective treatment is available. Several animal models of retinitis pigmentosa are used to elucidate its pathogenesis and to devise therapies. The retinal degeneration (rd1) mouse is one such animal model in which rod-specific phosphodiesterase (PDE) is in

Background: Several attempts to increase the locoregional control in locally advanced lung cancer including concurrent chemotherapy, accelerated fractionation and dose escalation have been made during the last years. As the EGFR directed antibody cetuximab has shown activity concurrent with radiotherapy in squamous cell carcinoma of the head and neck, as well as in stage IV NSCLC combined with che

Peak aerobic power in humans ((V) over dot(O2), peak) is markedly affected by inspired O-2 tension (F-IO2). The question to be answered in this study is what factor plays a major role in the limitation of muscle peak. (V) over dot(O2) in hypoxia: arterial O-2 partial pressure (P-a,(O2)) or O-2 content (C-a,C-O2)? Thus, cardiac output (dye dilution with Cardio-green), leg blood flow (thermodilution

Objectives To calculate the normal range for the fetal middle cerebral artery (MCA)/uterine artery pulsatility index (PI) ratio in the third trimester of pregnancy and to assess its value, compared with that of the MCA/umbilical artery PI ratio, in predicting an unfavorable outcome of pregnancies complicated by pre-eclampsia. Methods Doppler blood flow velocimetry of the uterine and umbilical arte

Background: Cardiovascular Magnetic Resonance (CMR) enables non-invasive quantification of cardiac output (CO) and thereby cardiac index (CI, CO indexed to body surface area). The aim of this study was to establish if CI decreases with age and compare the values to CI for athletes and for patients with congestive heart failure (CHF). Methods: CI was measured in 144 healthy volunteers (39 +/- 16 ye

The source contributions to carbonaceous PM2.5 aerosol were investigated at a European background site at the edge of the Po Valley, in Northern Italy, during the period January-December 2007. Carbonaceous aerosol was described as the sum of 8 source components: primary (1) and secondary (2) biomass burning organic carbon, biomass burning elemental carbon (3), primary (4) and secondary (5) fossil

En fältstudie på åtta mastarbetare utfördes under februari i Svealand och Norrland. Mastarbetarnas aktiviteter observerades under en vanlig arbetsdag i masten och hudtemperaturen på sju ställen på kroppen, kroppstemperatur och hjärtfrekvens registrerades kontinuerligt. De fick också skatta sin temperaturupplevelse och ansträngningsgrad flera gånger under dagen. Lufttemperaturen varierade mellan -1Désirée Gavhed, Kalev Kuklane, Ingvar Holmér. Work on masts in cold conditions. Arbetslivsrapport 1999:22. Eight tower operators were studied in February during their ordinary duties in masts in four regions of Sweden. The activities of the workers were observed during a full working day and the skin temperature at seven spots, body temperature and heart rate were measured continuously. They also

The principal fate during litter decomposition and mineralization is rather well established only for a limited number of elements, mainly essential plant nutrients and a few potentially very toxic metals. Elements which occupy the majority of the positions in the periodical system seems almost unknown in this context. The objectives were, therefore to assess differences in the behavior of 58 mine

Objective To compare, in young active adults with an acute anterior cruciate ligament (ACL) tear, the mid-term (five year) patient reported and radiographic outcomes between those treated with rehabilitation plus early ACL reconstruction and those treated with rehabilitation and optional delayed ACL reconstruction. Design Extended follow-up of prospective randomised controlled trial. Setting Ortho
