Solid-state phase behaviour of dodecylglycosides

The solid-state phase behaviour of lyophilised n-dodecyl-beta-D-glucoside (beta-C(12)G(1)), n-dodecyl-beta-D-maltoside (beta-C(12)G(2)) and n-dodecyl-beta-D-maltotrioside (beta-C(12)G(3)) has been investigated by differential scanning calorimetry (DSC) and X-ray techniques. For beta-C(12)G(1), lyophilisation results in a formation of a crystalline anhydrate. The lamellar spacing (37 angstrom) is c

Asymptotic distribution of Mann's test for trend for m-dependent seasonal observations

Mann proposed a non-parametric test for trend for independent non-seasonal observations. In this paper we generalize the test to m-dependent seasonal observations. Furthermore, an estimator of trend, based on Kendall's tau, is studied and its asymptotic distribution is proved to be normal. The results are exemplified by a moving average process.

The effects of calcitonin gene-related peptide (CGRP) on cochlear and mucosal blood flow in the albino rabbit

The effects of intravenously infused calcitonin gene-related peptide (CGRP) on the regional blood flow of the cochlea, the middle ear and the upper respiratory tract were studied. Two series of experiments were performed without pretreatment on either conscious or pentobarbital anaesthetized animals; in one series the cervical sympathetic chain was severed on one side; in another series anaestheti

Solid electrolyte membranes from semi-interpenetrating polymer networks of PEG-grafted polymethacrylates and poly(methyl methacrylate)

Solid polymer electrolyte membranes were prepared as semi-interpenetrating networks by photo-induced polymerization of mixtures of poly(ethylene glycol) (PEG) methacrylate macromonomers in the presence of poly(methyl methacrylate) (PMMA) and lithium bis(trifluoromethanesulfonyl)imide salt. The composition of the membranes was varied with respect to the PMMA content, the degree of cross-linking, an

Risk of mortality following hip fracture in Japan

Background. Excessive mortality and morbidity are serious problems after hip fracture in the elderly. Methods. Hip fractures in persons aged 50 years or older were prospectively registered in Japan in 2000. Questionnaires regarding both the first onset and the second 120-day period after hip fracture were obtained from 759 patients, 546 of whom were female and 213 male. Results. Their average age

Quality of planar whole-body bone scan interpretations - a nationwide survey

Purpose The purpose of this study was to investigate, in a nationwide study, the inter-observer variation and performance in interpretations of bone scans regarding the presence or absence of bone metastases. Methods Bone scan images from 59 patients with breast or prostate cancer, who had undergone scintigraphy due to suspected bone metastatic disease, were studied. The patients were selected to

Phosphorus effects on metabolic processes in monoxenic arbuscular mycorrhiza cultures

The influence of external phosphorus (P) on carbon (C) allocation and metabolism as well as processes related to P metabolism was studied in monoxenic arbuscular mycorrhiza cultures of carrot (Daucus carota). Fungal hyphae of Glomus intraradices proliferated from the solid minimal medium containing the colonized roots into C-free liquid minimal medium with different P treatments. The fungus formed

The workplace lunchroom: an arena for multicultural eating

Many countries in Europe have experienced growing migration since World War II. It is estimated that more than one in five Swedes living today has roots in other countries and cultures. Segregation in terms of ethnic origin in housing areas makes it easier to maintain the language and cultural traditions of the home country when it comes to cooking and eating. In extremely segregated housing areas

Continuous-index hidden Markov modelling of array CGH copy number data.

Motivation: In recent years, a range of techniques for analysis and segmentation of array comparative genomic hybridization (aCGH) data have been proposed. For array designs in which clones are of unequal lengths, are unevenly spaced or overlap, the discrete-index view typically adopted by such methods may be questionable or improved. Results: We describe a continuous-index hidden Markov model for

Accrual rate-limiting factors in a Swedish randomised ductal carcinoma in situ (DCIS) trial - a demographic study

In the last two decades the introduction of mammographic screening in the Western world has increased the number of diagnosed ductal carcinomas in situ (DCIS) considerably. In situ carcinoma of the breast is considered a heterogeneous disease, the natural history of which is not well known. Thus, appropriate treatment needs to be established. For this reason, a randomised trial studying the effect

New Ar-40/Ar-39 alunite ages from the Colquijirca district, Peru: evidence of a long period of magmatic SO2 degassing during formation of epithermal Au-Ag and Cordilleran polymetallic ores

We present Ar-40/Ar-39 data acquired by infra-red (CO2) laser step-heating of alunite crystals from the large Miocene Colquijirca district in central Peru. Combined with previously published data, our results show that a long (at least 1.3 My) and complex period of magmatic-hydrothermal activity associated with epithermal Au-(Ag) mineralization and base metal, Cordilleran ores took place at Colqui

H-2(e,e ' p)n reaction at high recoil momenta

The 2H(e,e(')p)n cross section was measured in Hall A of the Thomas Jefferson National Accelerator Facility near the top of the quasielastic peak (x(Bj)=0.964) at a four-momentum transfer squared, Q(2)=0.665 (GeV/c) (2) (omega=0.368 GeV, W=2.057 GeV), and for recoil momenta up to 550 MeV/c. The measured cross section deviates by 1-2sigma from a state-of-the-art calculation at low recoil momenta. A

Candelariella (Candelariaceae) in western United States and northern Mexico: the 8-spored, lecanorine species

This paper treats 12 Candelariella species occurring in western North America characterized by having lecanorine apothecia and 8-spored asci. Six new names are proposed: C. aggregata, C. californica, C. complanata, C. corallizoides, C. deppeanae and C. inmarginata. Candelariella terrigena and C. deflexa are treated as synonyms of C. citrina and C. aurella, respectively. Candelariella kansuensis is

Outcomes for reduced-intensity allogeneic transplantation for multiple myeloma: an analysis of prognostic factors from the Chronic Leukaemia Working Party of the EBMT

We report the outcome of 229 patients who received an allograft for myeloma with reduced-intensity conditioning (RIC) regimens from 33 centers within the European Group for Blood and Marrow Transplantation (EBMT). The median age was 52 years and 64% were male. Conditioning regimens were heterogeneous, but most were fludarabine based and T cell depleted with antithymocyte globulin or alemtuzumab. T

Perfusion magnetic resonance imaging of the lung: characterization of pneumonia and chronic obstructive pulmonary disease. A feasibility study

Perfusion magnetic resonance (MR) imaging is a promising new method for detection of perfusion defects in the diagnosis of pulmonary embolism. In the present study we evaluated the first-pass characteristics of perfusion MR imaging in patients with pneumonia or chronic obstructive pulmonary disease (COPD), frequent differential diagnoses to pulmonary embolism. Dynamic contrast-enhanced MR images o

Concomitant contact allergy to the resins, reactive diluents and hardener of a bisphenol A/F-based epoxy resin in subway construction workers

An outbreak of suspected contact dermatitis among subway construction workers was suspected to be due to a new bisphenol A/F-based epoxy resin system (ERS). The construction workers used ERSs during the insertion of iron bars into concrete walls. The objective of the study was to determine the components (if any) of the ERS responsible for the contact allergy. Patch testing was performed on 20 of
