Over a one-year study period (2003), we monitored total Hg (HgT) and methyl Hg (MeHg) at two sites in a Swedish forest stream located above (Site(ref)) and below a stretch of Hg-contaminated sediments (Site(Hg)). We also monitored HgT, MeHg, and ancillary water chemistry in peat water close to the stream and HgT in open field wet deposition. Despite the presence of historical Hg contaminants, dire

INTRODUCTION: Early identification of Alzheimer's disease (AD) is needed both for clinical trials and in clinical practice. In this study, we compared brief cognitive tests and cerebrospinal fluid (CSF) biomarkers in predicting conversion from mild cognitive impairment (MCI) to AD. METHODS: At a memory clinic, 133 patients with MCI were followed until development of dementia or until they had bee

We pursued the following three interconnected points: (1) there are unexplored opportunities for resilience scholars from different disciplines to cross-inspire and inform, (2) a systems perspective may enhance understanding of human resilience in health and social settings, and (3) resilience is often considered to be fractal, i.e., a phenomenon with recognizable or recurring features at a variet

Copper homeostasis is important for virulence of the fungus Cryptococcus neoformans, which can cause lethal meningoencephalitis in humans. Cryptococcus cells encounter high copper levels in the lung, where infection is initiated, and low copper levels in the brain. Here we demonstrate that two Cryptococcus copper transporters, Ctr1 and Ctr4, differentially influence fungal survival during pulmonar

This report contains a verification method that could be applied when evaluating trail fire safety design in a performance-based code environment. The report is focused on design alternatives (i.e. design alternatives) where fire sprinkler systems have an important role. Three possible verification methods are proposed together with the procedure on how they could be applied in design. The covered

The objective of this study was to examine to what extent ergonomics simulations of manual assembly tasks correctly predict the real outcomes in the plants and if recommended measures originating from ergonomics simulations are taken into consideration. 155 ergonomics simulation cases were used in the study and all cases were performed by nine simulation engineers at Volvo Car Corporation in Gothe

Questions: How will genetic differentiation and genetic drift in spatially structured populations be affected by different classes of autocorrelated environmental noise? How does dispersal interact with fluctuations generated from the demographic and environmental forcing in shaping the neutral genetic patterns? Model and key assumptions: Populations are regulated locally by density-dependent feed

Objective: Systemic lupus erythematosus (SLE) is a complex multi-organ disease, characterised by relapses and remissions. Designing a high-quality randomised controlled trial poses many challenges. We have developed evidenced-based recommendations for points to consider in conducting clinical trials in patients with SLE. Methods: The EULAR Task Force on SLE comprised 19 specialists and a clinical

Small for gestational age (SGA) is considered as an indicator of intrauterine growth restriction, and multiple maternal and newborn characteristics have been identified as risk factors for SGA. This knowledge is mainly based on measures of average association (ie, OR) that quantify differences in average risk between exposed and unexposed groups. Nevertheless, average associations do not assess th

The objective of the study was to compare disease characteristics over the first 5 years of disease in patients with RA, with disease onset in 1990s and 2000s, respectively.

Antenna Q optimization by a genetic algorithm with method of moments simulation at a single frequency is described. The optimized antennas may have arbitrary shapes within a rectangular region. Simulations using a commercial tool show good agreement between the predicted and realized Q factor. Furthermore, comparison with the physical bound shows that the optimized antennas perform close to the op

Background: Medial temporal lobe atrophy (MTA) is an early sign of Alzheimer's disease (AD). The current method of choice for measuring MTA is volumetric measurement based on 3D magnetic resonance imaging (MRI), but this complicated method has not been implemented clinically. Purpose: To investigate whether simple computed tomography (CT) linear measurements of the brain could be of value in AD wo

AIMS: To evaluate multi-frequency tactilometry as a method to measure vibrotactile sense in the sole of the foot in subjects with diabetes. METHODS: Vibration thresholds were investigated at five frequencies (8, 16, 32, 64 and 125 Hz) at three sites (first and fifth metatarsal heads and heel) in the sole of the foot in subjects with Type 1 and Type 2 diabetes (n = 37). Thresholds were compared wit

Popular Abstract in Swedish Hjärt-kärlsjukdom är en av västvärldens stora folksjukdomar. I Sverige drabbas årligen cirka 10 000 personer av plötsligt hjärtstopp. Den vanligaste orsaken är att en akut hjärtinfarkt orsakar ett ”elektriskt kaos” i hjärtat. Vid ett hjärtstopp upphör blodförsörjningen till hjärnan, vilket leder till medvetslöshet inom några sekunder och inom några få minuter börjar hjäThis thesis focuses on the prognostic value of electroencephalography(EEG) in comatose patients resuscitated after cardiac arrest (CA), using both simplified continuous EEG monitoring (cEEG) and routine EEG. Background: Comatose survivors are admitted to an intensive care unit (ICU) to support vital functions. Postresuscitation care includes target temperature management (TTM) for 24 hours. The d

Human stature as a measurement for evaluating physical status is used by the World Health Organiza-tion (WHO) as well as bioarchaeologists. The reason for this is that only about 80% depends on genetic factors, while 20% depend on the environment. Bad living conditions decrease stature in a population. This paper aims to make a short review of earlier reports on stature in Late Neolithic–Early Bro
