A pooled analysis of karyotypic patterns, breakpoints and imbalances in 783 cytogenetically abnormal multiple myelomas reveals frequently involved chromosome segments as well as significant age- and sex-related differences.

The cytogenetic features (ploidy, complexity, breakpoints, imbalances) were ascertained in 783 abnormal multiple myeloma (MM) cases to identify frequently involved chromosomal regions as well as a possible impact of age/sex. The series included MM patients from the Mitelman Database of Chromosome Aberrations in Cancer and from our own laboratory. Hyperdiploidy was most common, followed by hypodipl

Fatigue crack propagation in Ti-6Al-4V subjected to high strain amplitudes

Fatigue crack propagation in circular Ti-6Al-4V specimens subjected to high strain amplitudes has been investigated. Crack closure was measured with an electrical potential-drop technique. Closure was shown not to depend on strain ratio but to be a function of the applied strain range. At higher strain ranges, the crack was found to be closed for a smaller part of the load cycle than at lower stra

Prognostic significance of maximum tumour (bulk) diameter in young patients with good-prognosis diffuse large-B-cell lymphoma treated with CHOP-like chemotherapy with or without rituximab: an exploratory analysis of the MabThera International Trial Group (MInT) study

Background The definition and role of bulky disease in young patients (ie, aged 18-60 years) with good-prognosis diffuse large-B-cell lymphoma (DLBCL), who have been treated with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone)-like chemotherapy with or without rituximab, remain controversial. We aimed to assess the effect of maximum tumour diameter (MTD) in these patients. Meth

Familial risks for hospitalized Graves' disease and goiter

Objectives: Familial Clustering of a disease is an indicator of a possible heritable Cause. provided that environmental sharing can be excluded. Thus. data on familial risks are important For genetic Studies and for clinical genetic counseling. Design: We carried Out a nationwide family study on nontoxic and toxic nodular goiters, and Graves' disease in order to search for familial clustering of t

Cholinergic neuronal defect without cell loss in Huntington's disease.

Huntington's disease (HD) is a neurodegenerative disorder caused by a CAG-repeat expansion in the huntingtin (IT15) gene. The striatum is one of the regions most affected by neurodegeneration, resulting in the loss of the medium-sized spiny neurons. Traditionally, the large cholinergic striatal interneurons are believed to be spared. Recent studies demonstrate that neuronal dysfunction without cel

Free volume and density gradients of amorphous polymer surfaces as determined by use of a pulsed low-energy positron lifetime beam and PVT data

Density gradient widths at the polymer-vacuum surfaces of poly(methyl methacrylate), styrene-co-acrylonitrile, and styrene-co-maleic anhydride were quantified to 2, 5, and 4 rim, respectively, by use of a pulsed low-energy positron lifetime beam and to approximately 1.5 nm for all three polymers on the basis of theoretical predictions from pressure-volume-temperature (PVT) data, making use of the

Transfer of IgA deficiency to a bone-marrow-grafted patient with aplastic anaemia

IgA deficiency developed in a 2-year-old boy with aplastic anaemia who received a bone-marrow graft from his HLA-identical, 6-year-old, IgA-deficient sister. Southern blot analysis revealed the presence of alpha-genes in both children, thus suggesting a defect of lymphocyte stem-cell differentiation as a cause of IgA deficiency. Tissue typing showed homozygosity of HLA A1, B8, DR3, the haplotype a

Different strategies for controlling DNA conformation: compaction and decompaction.

In the present review we summarize different strategies to induce DNA compaction and decompaction. DNA compaction is achieved using different cationic co-solutes, such as trivalent ions, surfactant, and polycations. In addition, single-chained DNA compaction can also be achieved in solvents with low dielectric constants and by confinement. The decompaction strategies depend, naturally, on the meth

A goal oriented indicator framework to support integrated assessment of new policies for agri-environmental systems

The goal oriented framework (GOF) for indicators has been developed as part of a comprehensive research project developing computerised tools for integrated assessment of the effects of new policies or technologies on agricultural systems (SEAMLESS-IF). The ambition has therefore been to create an indicator framework where the environmental, economic and social dimensions of sustainable developmen

Selection for synchronous breeding in the European starling

Colonial birds often demonstrate considerable breeding synchrony. In southern Sweden the semi-colonial European starling initiated the vast majority of clutches within one week. Laying dates were positively skewed so that many birds initiated clutches at similar dates early in the season. Breeding was further synchronised by a particularly strong clutch-size reduction equivalent to one third of an

Identification of the phosphorylation site in vitro for cAMP-dependent protein kinase on the rat adipocyte cGMP-inhibited cAMP phosphodiesterase

Rat adipocyte cGMP-inhibited cAMP phosphodiesterase (cGI-PDE) appears to be dually regulated in intact cells by serine phosphorylations induced by isoprenaline and insulin, respectively (Degerman, E., Smith, C. J., Tornqvist, H., Vasta, V., Belfrage, P., and Manganiello, V. C. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 533-537; Smith, C. J., Vasta, V., Degerman, E., Belfrage, P., and Manganiello, V.

Effect of red wine marinades on the formation of heterocyclic amines in fried chicken breast

Genotoxic heterocyclic amines (HAs) are formed via the Maillard reaction and free radical reaction mechanisms when meat or fish is cooked at usual cooking conditions. In this paper, the effect of the addition of red wine was tested to study if it interferes in HA formation. Fried chicken breast was the food item chosen, and three different red wines, characterized in terms of grape varieties, free

Modelling of an electric IR heater at transient and steady state conditions Part II: modelling a paper dryer

A model for an electric infrared (IR) paper dryer has been developed. The model includes non-grey radiative heat transfer between the different parts of the IR heater, as well as conduction in reflector material and convective cooling of surfaces. Such heat transfer calculations are combined with energy balances to provide a system of equations that simulates the behaviour of an electric III dryer

The lactic acid bacteria involved in the production of bee pollen and bee bread

Recently a large flora of lactic acid bacteria (LAB) was identified in the honey stomach of the honey bee Apis mellifera. In this study, the presence of this flora in bee pollen and bee bread was investigated. Pollen was collected from the legs of honey bees, and both two week old and two month old bee bread were also obtained for the study. Bacterial isolates cultivated from these bee products we

Functional consequences of mutations in the MODY4 gene (IPF1) and coexistence with MODY3 mutations

Aims/hypothesis. The aim of this study was to examine the putative role of mutations in the insulin promoter 1 (IPF1) gene in early-onset diabetes. Methods. We carried out mutation screening of the IPF1 gene in 115 Scandinavian families with at least two members with onset of diabetes younger than 40 years. The allele frequencies were also tested in 183 unrelated patients with late-onset Type II (

Quantifying light and ultraviolet radiation in plant biology

Fluence rate and irradiance, two parameters used to quantify light and ultraviolet radiation, do not have a constant relation under natural fight conditions, A method is described for measuring fluence rate, the preferred parameter, using meters intended for irradiance measurements. Values measured under natural light conditions are compared to a daylight model.

Integrated assessment of soil chemical status. 2. Application of a regionalised model to 622 forested sites in Switzerland.

A model, MAKEDEP, was developed for reconstructing historic atmospheric deposition and nutrient uptake for forests using present day values. Deposition is reconstructed by separation of wet deposition and throughfall into five different categories. Dry deposition is assumed to depend linearly on needle biomass. Non-marine deposition is scaled using general European emission and deposition trends f
