The article is a description and evaluation of extensive and intensive field survey as a means of locating sites from the bronze and early iron ages in the cultivated landscape of southern Sweden. It includes a discussion of other field survey efforts and recommendations about survey technique. Surface survey in December proved to be a fairly successful means of locating bronze age remains in clay

It has been suggested that autochthonous (internally produced) organic carbon and allochthonous (externally produced) organic carbon are utilized by phylogenetically different bacterioplankton. We examined the relationship between the source of organic matter and the structure and function of lake bacterial communities. Differences and seasonal changes in bacterial community composition in two lak

Irritable bowel syndrome has a negative impact on a person's quality of life, but only a few existing studies have been based on patients' own perceptions. This study therefore aimed to collect information on the view of female patients with irritable bowel syndrome regarding what constitutes a good quality of life for them and to create a healthcare model for these patients. For the study, 30 wom

Dispersive liquid-liquid microextraction (DLLME) and high performance liquid chromatography-diode array detection (HPLC-DAD) was presented for extraction and determination of Irganox 1010, Irganox 1076 and Irgafos 168 (antioxidants) in aqueous samples. Carbon tetrachloride at microliter volume level and acetonitrile were used as extraction and dispersive solvents, respectively. The main advantages

A large pulse of atmospheric Cl-36 generated by a limited number of nuclear tests peaked in the late 1950s to early 1960s. The corresponding enhanced Cl-36 deposition is seen in various glaciological archives in the Northern Hemisphere. The profile of the bomb spike recorded in firn layers at Vostok Station, central East Antarctica. has been measured by employing accelerator mass spectrometry (AMS

Purpose. To define the association between venous volume as measured with air-plethysmography and the duplex ultrasound measured diameter of incompetent perforator of the lower limb. Patients and methods. Thirty-six patients with chronic venous disease were investigated with air-plethysmography and duplex ultrasound. Venous volume and venous filling time was measured. Venous filling index was calc

Objective: To design an economic model describing the costs and outcomes for patients treated with tumour necrosis factor alpha ( TNF alpha) inhibitors for rheumatoid arthritis ( RA) in current clinical practice in Sweden, to be used as a tool to estimate cost- effectiveness of the next generation of treatments. Methods: The model was constructed as a discrete event simulation ( DES) model analyse

Neurofibromatosis is associated with mid-aortic dysplasia, renal artery aneurysms and renal artery ostial stenosis, or occlusions in about 1% of cases. We describe a novel approach to recanalize an occluded renal artery in a 10-year-old girl with neurofibromatosis and difficulty in pharmacologically controlling her hypertension. Normally, when reconstruction is required, an open operative techniqu

Cyclic AMP potentiates glucose-stimulated insulin release and mediates the stimulatory effects of hormones such as glucagon-like peptide 1 (GLP-1) on pancreatic b-cells. By inhibition of cAMP-degrading phosphodiesterase (PDE) and, in particular, selective inhibition of PDE3 activity, stimulatory effects on insulin secretion have been observed. Molecular and functional information on b-cell PDE3 is

Heparan sulfate 3-O-sulfotransferase transfers sulfate to the 3-OH position of a glucosamine residue of heparan sulfate (HS) to form 3-O-sulfated HS. The 3-O-sulfated glucosamine residue contributes to two important biological functions of HS: binding to antithrombin and thereby carrying anticoagulant activity, and binding to herpes simplex viral envelope glycoprotein D to serve as an entry recept

In this paper, which was prepared as part of IEA Bioenergy Task XV (“Greenhouse Gas Balances of Bioenergy Systems”), we outline a standard methodology for comparing the greenhouse gas balances of bioenergy systems with those of fossil energy systems. Emphasis is on a careful definition of system boundaries. The following issues are dealt with in detail: time interval analysed and changes of carbon

So far, the use of epostane, a relatively new inhibitor of 3 beta-hydroxysteroid dehydrogenase/delta 5-delta 4 isomerase enzyme system (3 beta-HSD), has been confined to short-term interference with luteal and placental function. This study explored whether epostane treatment from the beginning of the cycle for approximately 1 month would also inhibit ovarian follicular function. Twenty females wi

Many paleoceanographic reconstructions of the glacial North Atlantic include estimates of iceberg discharge, which are based on the variable abundance of ice-rafted detritus (IRD) in deep-sea sediments. IRD abundance is most often determined by the mechanical separation and painstaking counting of terrigenous particles larger than a specified threshold grain size, typically 150 mum. Here we presen

Even though the concept of health and its importance has been widely discussed in health care during recent decades, mental health services have been criticised for adopting a biomedical perspective, which does not sufficiently consider the concept of health. The aim of the present study was to investigate the psychometric properties of the Health Questionnaire, a newly developed questionnaire to

There is no general agreement on the spirometric definition of chronic obstructive pulmonary disease (COPD). The global initiative for obstructive lung disease recommends a fixed ratio between forced expiratory volume in one-second (FEV1 ) and forced vital capacity (FVC) of <0·7 (FR) for the diagnosis of COPD. European Respiratory Society and American Thoracic Society favour the use of the fifth p

Fluorescence spectroscopy is one of many optical methods that are potentially clinically useful for noninvasive detection and characterization of disorders on the cervical part of uterus, including precancerous lesions. The cervix uteri exhibits a biologically complex tissue and the morphology of a biopsy is generally not homogenous. The standard histopathological protocol accounts only for the mo

Abstract Purpose: To evaluate the midterm outcomes and potential risk factors associated with the fascia suture technique (FST) for closure of femoral artery access sites after percutaneous endovascular aneurysm repair (EVAR). Methods: Between April 2007 and April 2008, 100 consecutive EVAR cases were evaluated retrospectively. A third of the procedures were emergent (16 ruptured aneurysms). Of th
