Gastrointestinal stromal tumor (GIST) has been considered radiation-resistant, and radiotherapy is recommended only for palliation of bone metastases in current treatment guidelines. No registered prospective trial has evaluated GIST responsiveness to radiotherapy.
We have characterized a stereospecific transport mechanism for L-dopa into human epidermal Langerhans cells (LCs). It is different from any other amino acid transport system. It is highly concentrative, largely pH-independent, and independent of exogenous Na+, glucose and oxygen, and fuelled by a renewable intracellular energy source inhibited by iodoacetate but not by arsenate. We propose that th
We have previously suggested that the Toluidine Blue (TB) test can be used for sperm chromatin structure assessment. In this study, we wished to evaluate the clinical applicability of the TB test in assessing male fertility potential using well-defined groups of fertile and infertile men. Sixty-three fertile and 79 infertile men were tested. Infertility thresholds for the proportion of sperm with
Objective. To follow patients with fibromyalgia six and 24 months after they finished a six-month treatment programme. The programme comprised pool exercise therapy, adjusted to the patients' limitations, and education based on their health problems. Methods. Twenty-six patients were examined six and 24 months after the completion of the treatment programme with the Fibromyalgia Impact Questionnai
International reference materials such as International Standard reagents facilitate quality assurance of essential biopharmaceutical products and related in vitro diagnostic tests. Standardization of antibody and DNA measurements and harmonization of laboratory procedures are key to the success of cancer prevention strategies through screening methods as well as for development and implementation
We compared the Q10 relationship for root-derived respiration (including respiration due to the root, external mycorrhizal mycelium and rhizosphere microorganisms) with that of mainly external ectomycorrhizal mycelium and that of bulk soil microorganisms without any roots present. This was studied in a microcosm consisting of an ectomycorrhizal Pinus muricata seedling growing in a sandy soil, and
Objectives. To compare the outcome of a microwave thermotherapy feedback system that is based on intraprostatic temperature measurement during treatment (ProstaLund Feedback Treatment or PLFT) with transurethral resection of the prostate (TURP) for clinical benign prostatic hyperplasia (BPH) in a randomized controlled multicenter study. The safety of the two methods was also investigated. Methods.
Characterization of the count-rate performance of scintillation cameras should include not only the specification of count losses. At high count rates, there is also an image distortion due to the mispositioning of pile-up events. In this paper a simple and clinically relevant procedure to quantify this distortion is presented. The images of a square uniform technetium-99m phantom at high and low
The tremendous amount of multimedia applications running across the wireless communication medium makes quality of service (QoS) a fundamental requirement for mobile ad hoc networks. However, it is not easy to incorporate QoS into these networks. Moreover, the growing number of group-oriented applications also necessitates the efficient utilisation of network resources. The multicast model is a pr
A superdeformed rotational structure is reported in the stable nucleus Zn-68. It has a transition quadrupole moment (Q(t)) of 2.5(-0.4)(+0.7) e b (beta(2) approximate to 0.4), as measured by the residual Doppler shift method. Theoretical calculations suggest that two different configurations are possible candidates for this band. One is built without h(11/2) neutrons, as seen in superdeformed band
OBJECTIVE: To evaluate the diagnostic potential of cerebrospinal fluid (CSF) levels of tau and beta-amyloid protein ending at amino acid 42 (Abeta42) as biomarkers for Alzheimer disease (AD) in clinical practice. DESIGN: A 1-year prospective study. SETTING: Community population-based sample of all consecutive patients admitted for investigation of cognitive symptoms to the Pitea River Valley Hospi
In the microelectronics industry, gold electrodes on silicon dioxide are produced using an adhesive layer of chromium or titanium. This method is applicable whenever a dry environment is present. However, when such an electrode is exposed to an electrolyte a galvanic cell is formed and the less noble metal will dissolve and eventually destroy the electrode. We describe here how a monolayer of merc
Open interviews with 13 fathers were performed, using a hermeneutic phenomenological method, to illuminate their lived experience of caring for their preterm infant. Their lived experience was expressed as a process moving from initial feelings of distance toward feelings of proximity. The process was described as a pendulum that was easily disturbed. Feelings of distance included experiences of l
In order to get to know the loads on bone and other tissues there is a need to measure motion. So far, the best way of measuring human locomotion is done in a gait laboratory. But since the equipment is quite expensive and it isn’t mobile, it cannot be used for measuring on people during their daily activities. There is a great interest of finding easier ways to capture the motion in daily situat
This article proceeds from the argument that various forces of globalization have resulted in increased dislocation and uncertainty for many people in the world. Religion and nationalism, compared to most other identity constructions, are viewed as particularly relevant organizing principles at a time when modern society is making increasing demands on individuals. In comparison to much constructi
Hereditary severe combined immunodeficiency (SCID) includes a heterogeneous group of diseases that profoundly affect both cellular and humoral immune responses and require treatment by bone marrow transplantation. Characterization of the cellular and molecular bases of SCID is essential to provide accurate genetic counseling and prenatal diagnosis, and it may offer the grounds for alternative form
Differential elliptic flow (v(2)) for phi mesons and (anti)deuterons ((d) over bar )d is measured for Au + Au collisions at root s(NN) = 200 GeV. The v(2) for phi mesons follows the trend of lighter pi(+/-) and K-+/- mesons, suggesting that ordinary hadrons interacting with standard hadronic cross sections are not the primary driver for elliptic flow development. The v(2) values for ((d) over bar
BACKGROUND: The in vitro contracture test (IVCT) is the golden standard to diagnose malignant hyperthermia susceptibility (MHS). A high reproducibility is important for a high validity of a test. METHODS: We have therefore analyzed IVCT in 838 patients, investigated in two laboratories. Each halothane and caffeine test was performed in two muscle strips. The test results were analyzed with respect
