In vitro screening for antitumour activity of Clinopodium vulgare L. (Lamiaceae) extracts.
Aqueous extract of Clinopodium vulgare L. showed strong antitumour activity when tested in vitro on A2058 (human metastatic melanoma), HEp-2 (epidermoid carcinoma, larynx, human) and L5178Y (mouse lymphoma) cell lines-6 h after treatment disintegration of the nuclei and cell lysis started. Applied at a concentration of 80 microg/ml it reduced the cell survival to 1.0, 5.6 and 6.6%, respectively. T
Microwave-assisted extraction of zearalenone from wheat and corn
A microwave-assisted extraction (MAE) method has been developed for determination of zearalenone in wheat and corn by LC-MS with an atmospheric pressure chemical ionization interface (APCI). Matrix effects were minimized by use of matrix-matched standard curves for quantification of the analyte. The limit of quantification (LOQ) of the method was 30 ng g(-1) in wheat and 20 ng g(-1) in corn. The r
Effect of processing of sword beans (Canavalia gladiata) on physicochemical properties of starch
The effect of various processing methods on physico-chemical properties of sword bean starch was studied. Seed grits and flour were cooked with and without soaking, wet-autoclaved, and roasted. The changes in starch associated with these processing methods were studied by observing changes in granular structure, water solubility index, water absorption index, molecular size distribution and the de
Generalization of rapidly recurring seizures is suppressed in mice lacking glial cell line-derived neurotrophic factor family receptor alpha2.
Recent experimental evidence indicates that neurotrophic factors play a role in the pathophysiology of epilepsy. The objective of this study was to explore whether signaling through one of the glial cell line-derived neurotrophic factor family receptors, GFRα2, influences the severity of kindling-evoked, rapidly recurring seizures and the subsequent development of permanent hyperexcitability. We a
An experimental evaluation of the arctic fox (Alopex lagopus) as a seed disperser
Arctic foxes are evaluated as seed dispersal vectors for Greenlandic plant species through a feeding experiment with subsequent scat analysis and germination test. Seeds of 22 common species with different morphology were tested. Passage time ranged between 4 and 48 hours. No significant differences was detected in passage time for seeds with different morphology. Cerastium alpinum and Stellaria l
Methotrexate concentrations in cerebrospinal fluid and serum, and the risk of central nervous system relapse in children with acute lymphoblastic leukaemia
The aim of the study was to characterize the relationship between the pharmacolkinetics of methotrexate in serum and concentrations in the cerebrospinal fluid, and to analyse the association to risk of a central nervous system relapse in children with acute lymphoblastic leukaemia. In this retrospective study, 353 children with acute lymphoblastic leukaemia treated with high-dose methotrexate acco
IPVA-DNA cryogel membranes: Characterization, swelling, and transport studies
Double-stranded (ds) DNA from salmon testes has been incorporated into PVA hydrogels obtained by a technique of repeated freezing and thawing. The cryogels obtained are free of potential toxic species like chemical cross-linkers, and consequently, they can be used in pharmaceutical or medical applications. These cryogels show a good mechanical resistance and a white and opaque appearance caused by
Image analysis study of mould susceptibility of spruce and larch wood dried or heat-treated at different temperatures
In this study, mould growth on wood was investigated by image analysis. The studied parameters were drying and heat-treatment temperatures (20-210°C), original and resawn surface and different wood species (spruce and larch). Small specimens—some of which were inoculated with a spore suspension—were stored under humid conditions and photographed once a week. Mould growth was assessed by image anal
Integrin alphavbeta3 binding to human alpha5-laminins facilitates FGF-2- and VEGF-induced proliferation of human ECV304 carcinoma cells.
Human ECV304 cells respond reproducibly by tube formation to complex basement membrane matrices. Laminins are major glycoproteins of basement membranes. We therefore studied the ability of ECV304 cells to attach to defined laminin isoforms and to fibronectin, and identified the involved laminin receptors. The cells bound poorly to fibronectin, to some extent to laminin-1, whereas laminin-2/4 and -

Multiple spaced seeds for homology search
Motivation: Homology search finds similar segments between two biological sequences, such as DNA or protein sequences. The introduction of optimal spaced seeds in PatternHunter has increased both the sensitivity and the speed of homology search, and it has been adopted by many alignment programs such as BLAST. With the further improvement provided by multiple spaced seeds in PatternHunterll, Smith
Amelioration by cyclosporin A of brain damage following 5 or 10 min of ischemia in rats subjected to preischemic hyperglycemia
It has recently been shown that the immunosuppressant cyclosporin A (CsA) dramatically ameliorates the selective neuronal necrosis which results from 10 min of forebrain ischemia in rats. Since CsA is a virtually specific blocker of the mitochondrial permeability transition (MPT) pore which is assembled under adverse conditions, such as mitochondrial calcium accumulation and oxidative stress, the
Obtaining informed consent to neonatal randomised controlled trials: interviews with parents and clinicians in the Euricon study
BACKGROUND: Questions have been asked about whether the process of obtaining informed consent from parents to clinical trials on neonates leads to valid consent. We undertook a study in nine European countries to assess this issue and to seek any practical improvements. METHODS: Semi-structured interviews were conducted with parents of 200 babies who had been asked for consent to neonatal trials a
The Human Protein Atlas - a tool for pathology
Tissue-based diagnostics and research is incessantly evolving with the development of new molecular tools. It has long been realized that immunohistochemistry can add an important new level of information on top of morphology and that protein expression patterns in a cancer may yield crucial diagnostic and prognostic information. We have generated an immunohistochemistry-based map of protein expre

Pressure-volume curves with and without muscle paralysis in acute respiratory distress syndrome
OBJECTIVE: Pressure-volume (PV) curves are recorded after induction of complete muscle paralysis, which may limit their clinical use. The feasibility of recording PV curves without paralysis has not been tested. In 19 patients with acute respiratory distress syndrome (ARDS) and no hemodynamic instability we prospectively evaluated whether PV curves can be safely and reliably recorded under deep se
