Spatial Influence of Topographical Factors on Yield of Potato (Solanum Tuberosum L.) in Central Sweden

This study has evaluated the sampling density for creation of high-resolution digital elevation models (DEMs) for precision agriculture purposes. The relationships between yield and topographical factors were investigated in a study area located in the central Sweden province of Dalarna. The DEM data sampling was carried out with a RTK-GPS system. A dense sampling scheme was employed and data was

Changing pattern of care of boys with haemophilia in western European centres

Haemophilia management is not uniform among countries, even within western Europe, that have close economic, social and cultural relationship. The European Paediatric Network PedNet aims to share experiences in the field of the care of boys with haemophilia. In 1998, a PedNet survey has shown significant disparities in 20 centres from 16 countries, particularly as regards the implementation of pro

Long-Term Survival and Fracture Risk After Hip Fracture: A 22-Year Follow-Up in Women

Hip fracture is associated with high early mortality. Little is known about long-term survival and subsequent fracture risk. The aim of this study was to evaluate survival and fracture risk after hip fracture in women at different ages. All women suffering a hip fracture during 1984-1985 in Malmo, Sweden, were identified (n = 766) and followd up to 22 yr or death. All new radiographic examinations

Physical health a cluster randomized controlled lifestyle intervention among persons with a psychiatric disability and their staff

The objective was to explore the impact on physical health of a lifestyle programme among persons with psychiatric disabilities, and their caregivers. Their satisfaction with the intervention was also assessed. Somatic comorbidity and an increased mortality related to the lifestyle among persons with psychiatric disabilities are well known. Few randomized controlled trials have been aimed specific

Arguments Surrounding Organic and Genetically Modified Food Labelling: A Few Comparisons

This paper compares reasoning surrounding organic food labelling with arguments concerning mandatory GM labelling. Focus is placed on argumentative cross-overs, defined as cases where actors or organizations use a certain type of argumentation for one issue (for example, modes of food production), and shift into using their opponent's type of argumentation for a closely related issue (for example,

High prognostic specificity of antisocial personality disorder in patients with drug dependence: Results from a five-year follow-up

A sample of 125 consecutive patients from a Swedish detoxification unit were followed up at five years. Register data on criminal behavior were retrieved for 99% of all subjects, including those who were deceased at follow-up, and 76% of living subjects were interviewed. A diagnosis of antisocial personality disorder (ASPD) at intake was associated with incarceration, continuous drug use, dependen

Construct and discriminant validity and dimensionality of the Interview Schedule for Social Interaction (ISSI) in three psychiatric samples.

This study was aimed at investigating the psychometric properties of the Interview Schedule for Social Interaction (ISSI), in terms of construct and discriminant validity and unidimensionality, in three psychiatric samples with varying prerequisites for social interaction: 1) an outpatient sample of working age with mixed diagnoses, 2) an outpatient sample with schizophrenia, and 3) an inpatient s

Functional Analysis of the Factor IX Epidermal Growth Factor-Like Domain Mutation Ile66Thr Associated with Mild Hemophilia B.

he present study focused on the functional role of the mutation Ile66Thr located in the N-terminal epidermal growth factor-like domain of coagulation factor IX (FIX). This mutation causes mild hemophilia B with approximately 25% FIX coagulant activity and FIX antigen levels of around 90% of normal. In the 3-dimensional structure of porcine FIXa and in the subsequent 3-dimensional model of human FI

Computer-supported detection of M-components and evaluation of immunoglobulins after capillary electrophoresis

BACKGROUND: Electrophoresis of serum samples allows detection of monoclonal gammopathies indicative of multiple myeloma, Waldenstrom macroglobulinemia, monoclonal gammopathy of undetermined significance, and amyloidosis. Present methods of high-resolution agarose gel electrophoresis (HRAGE) and immunofixation electrophoresis (IFE) are manual and labor-intensive. Capillary zone electrophoresis (CZE

Differential effects of estrogen on DNA synthesis in human periodontal ligament and breast cancer cells.

BACKGROUND: It is important to clarify the biological function of the female sex hormones estrogen and progesterone in periodontal ligament cells, as these hormones may affect periodontal health. We have previously shown that human periodontal ligament cells express estrogen receptor beta (ERbeta) but not ERalpha, whereas human breast cancer cells (MCF7) express both ERalpha and ERbeta. Data on pr

Foraging among cannibals and kleptoparasites: effects of prey size on pike behavior

The northern pike (Esox lucius) is an important and selective piscivore that chooses smaller prey than predicted from energy / time budgets. In a laboratory experiment, we investigated pike predatory behavior to explain this selectivity. Northern pike feeding on different prey sizes in aquaria were observed when foraging alone, when in the presence of chemical cues from similar-sized or larger con

Multiple effects of alpha(1)-antitrypsin on breast carcinoma MDA-MB 468 cell growth and invasiveness

The degradation of extracellular matrix during cancer invasion results from the action of several protease and protease inhibitor systems. alpha(1)-Antitrypsin (AAT) is a serine proteinase inhibitor produced by various tumour cells, and its plasma concentration rises during inflammation, infection and malignant diseases. AAT is found in a native, inhibitory active form, but also in other, non-inhi

Cellulase production of Trichoderma reesei Rut C 30 using steam-pretreated spruce - Hydrolytic potential of cellulases on different substrates

Various techniques are available for the conversion of lignocellulosics to fuel ethanol. During the last decade processes based on enzymatic hydrolysis of cellulose have been investigated more extensively, showing good yield on both hardwood and softwood. The cellulase production of a filamentous fungi, Trichoderma reesei Rut C 30, was examined on carbon sources obtained after steam pretreatment o

Measurement of circulating forms of prostate-specific antigen in whole blood immediately after venipuncture: implications for point-of-care testing

BACKGROUND: The purpose of this study was to validate the use of whole-blood samples in the determination of circulating forms of prostate-specific antigen (PSA). METHODS: Blood samples of hospitalized prostate cancer and benign prostatic hyperplasia patients were collected and processed to generate whole-blood and serum samples. Three different rapid two-site immunoassays were developed to measur

Role of ventilation scintigraphy in diagnosis of acute pulmonary embolism: an evaluation using artificial neural networks.

The purpose of this study was to assess the value of the ventilation study in the diagnosis of acute pulmonary embolism using a new automated method. Either perfusion scintigrams alone or two different combinations of ventilation/perfusion scintigrams were used as the only source of information regarding pulmonary embolism. A completely automated method based on computerised image processing and a

Quantum mechanical free energy barrier for an enzymatic reaction

We discuss problems related to in silico studies of enzymes and show that accurate and converged free energy changes for complex chemical reactions can be computed if a method based on a thermodynamic cycle is employed. The method combines the sampling speed of molecular mechanics with the accuracy of a high-level quantum mechanics method. We use the method to compute the free energy barrier for a
