Pressurized liquid extraction (PLE) was investigated for the extraction of two endosulfan isomers and their metabolite from two real contaminated soil samples. PLE for 3 x 10 min at 100 degrees C was proven to be more exhaustive than Soxhlet extraction (SOX) in one soil sample. On the other soil sample investigated the method was found to be equally exhaustive as SOX. The use of hazardous organic
Background: The purpose of this project was to develop a telemedicine platform that supports home site monitoring and integrates biochemical, physiological, and dietary parameters for individual patients with hepatic glycogen storage disease (GSD). Methods and results: The GSD communication platform (GCP) was designed with input from software developers, GSD patients, researchers, and healthcare p
The optical klystron installed on the Elettra storage-ring is normally used as interaction region for an oscillator free-electron laser, but, removing the optical cavity and using an external seed laser, one obtains an effective scheme for single-pass harmonic generation. In this configuration the high-power external laser is synchronized with the electron beam entering the first undulator of the
Agroforestry practices support agricultural resilience against climatic variability, increase soil productivity, can diversify and increase farmers' incomes, and support native fauna in agricultural landscapes. However, many farmers are still reluctant to implement agroforestry practices. We distributed questionnaires to 75 agroforestry and 64 "conventional agriculture" small-scale farmers working
The mucopolysaccharidoses (MPS) are lysosomal storage disorders that result from defects in the catabolism of glycosaminoglycans. Impaired muscle, bone, and connective tissue are typical clinical features of MPS due to disruption of the extracellular matrix. Markers of MPS disease pathology are needed to determine disease severity and monitor effects of existing and emerging new treatments on dise
OBJECTIVE: In dynamic susceptibility contrast MRI (DSC-MRI), an arterial input function (AIF) is required to quantify perfusion. However, estimation of the concentration of contrast agent (CA) from magnitude MRI signal data is challenging. A reasonable alternative would be to quantify CA concentration using quantitative susceptibility mapping (QSM), as the CA alters the magnetic susceptibility in
Liquid biopsy allows assessment of multiple analytes, providing temporal information with potential for improving understanding of cancer evolution and clinical management of patients. Although liquid biopsies are intensely investigated for prediction and response monitoring, preanalytic variables are of primary concern for clinical implementation, including categories of collection method and sam
Control charts have typically been constructed using estimators obtained under assumptions of data independence and a given distribution of data. Here, I deal with cases in which neither of these conditions are satisfied. In particular, I consider the case of data obtained from a first-order autoregressive (AR(1)) time series model that have been contaminated by outlying process observations. I fi
Despite uneventful primary surgery, patients with cleft palate may experience velopharyngeal insufficiency (VPI) and hypernasal speech. Videoradiography of velopharynx is a commonly used method to visualize velopharyngeal function and a velopharyngeal flap is often used to counteract VPI. The aim of this study was to investigate whether the frontal projection on videoradiography plays a role in th
Background: Recent studies have shown that quantification of myocardial perfusion (MP) at stress and myocardial perfusion reserve (MPR) offer additional diagnostic and prognostic information compared to qualitative and semi-quantitative assessment of myocardial perfusion distribution in patients with coronary artery disease (CAD). Technical advancements have enabled fully automatic quantification
In the study presented in this paper a single-cylinder Scania D12 diesel engine has been converted to work as a pneumatic hybrid. During pneumatic hybrid operation the engine can be used as a 2-stroke compressor for generation of compressed air during vehicle deceleration and during vehicle acceleration the engine can be operated as an air-motor driven by the previously stored pressurized air.The
Background and purpose — The number of patients where shoulder hemiarthroplasty (SHA) is an option is still substantial. Descriptive analyses performed by the Swedish Shoulder Arthroplasty Registry (SSAR) showed that while patients receiving SHA designs, i.e. resurfacing hemi (RH) and stemmed hemi (SH), reported similar shoulder functionality and quality of life, the revision rate for RH (12%) was
A commercially available NaI(Tl) based spectrometer-dosimeter has been used to separate contributions of the terrestrial radionuclides (238U series, 232Th series and 40K) and 137Cs to the total ambient dose equivalent rate (ADER), Ḣ*(10) , outdoors. The device had been initially calibrated by the manufacturer to measure: 1) the total ADER; 2) activity concentrations of 226Ra, 232Th, 40K and ‘effec
Background and purpose — The decision on and the outcome of treatment for a slipped capital femoral epiphysis (SCFE) depend on the severity of the slip. In 2015, web-based registration was introduced into the Swedish Pediatric Orthopedic Quality (SPOQ) register. To determine whether the inclusion of commonly used methods in Sweden for radiographic measurement of SCFE (the calcar femorale [CF] meth
The lack of treatments during the recent Ebola and Zika outbreaks dramatically exposed the vulnerability of the global health system and the dire consequences thereof. But even where therapies against infectious diseases had been available, an additional threat has gained world-wide attention: antimicrobial resistance (AMR). A growing number of microbial organisms are becoming resistant to availab
Continuous water-table (WT) measurements from peatlands are scarce and – if existing at all –very short. Consequently, proxy indicators are critically needed to simulate hydrological changes in peatlands over longer time periods. In this study, we demonstrate that tree-ring width (TRW) records of Scots pine (Pinus sylvestris L.) growing in the Čepkeliai peatland (southern Lithuania) can be used as
BACKGROUND: Chronic subdural hematoma (cSDH) is one of the most common conditions encountered in neurosurgical practice. Recurrence, observed in 5-30% of patients, is a major clinical problem. The temperature of the irrigation fluid used during evacuation of the hematoma might theoretically influence recurrence rates since irrigation fluid at body temperature (37oC) may beneficially influence coag
Background Renal elimination normally decreases with age. Nonsteroidal antiinflammatory drugs (NSAIDs) carry a risk of additional kidney damage. Objective The aims of this study were to assess the prevalence of NSAIDs in the elderly (aged ≥ 65) population in Sweden, explore reasons for any possible differences in the level of use and assess their kidney functions. Setting Data were obtained from t
Islet cell antibodies (ICA) are a specific marker for Type 1 (insulin-dependent) diabetes mellitus. ICA are found in the serum of over 80% of newly diagnosed patients and the levels of ICA are directly of prognostic value. Standardisation of ICA and the uniform reporting of ICA levels in international units is critical to preclinical/clinical research and the development of assays for ICA as diagn
