Filetype
Elater ferrugineus is a saproxylic click beetle inhabiting old deciduous trees in Europe. It is threatened throughout its area of distribution due to habitat loss. No efficient monitoring method has been available for this species, but observed attraction of females to (R)-(+)-γ-decalactone, which is a male-produced sex pheromone of its prey, the scarab beetle Osmoderma eremita, has led to the dev
Whether chromosome abnormalities observed in tumor cells may in some cases reflect low-grade somatic mosaicism for anomalies present already at zygote formation, rather than acquired somatic mutations, has for long remained a speculation. We here report a patient with Wilms tumor, where constitutional somatic mosaicism of trisomy 8 was detected in a previously healthy 2 ½-year-old boy. Single Nucl
Male breast cancer (MBC) is a rare disease that shares both similarities and differences with female breast cancer (FBC). The aim of this study was to assess genome-wide DNA methylation profiles in MBC and compare them with the previously identified transcriptional subgroups of MBC, luminal M1 and M2, as well as the intrinsic subtypes of FBC. Illumina's 450K Infinium arrays were applied to 47 MBC
During sporulation of Streptomyces coelicolor, the cytokinetic protein FtsZ is assembled into dozens of regularly spaced Z rings, which orchestrate the division of aerial hyphae into spores. We have previously found that a missense allele of ftsZ, ftsZ17(Spo), primarily affects sporulation septation rather than formation of cross-walls in vegetative mycelium. To clarify what aspect of FtsZ functio
Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in children and adolescents. Alveolar (ARMS) and embryonal (ERMS) histologies predominate, but rare cases are classified as spindle cell/sclerosing (SRMS). For treatment stratification, RMS is further subclassified as fusion-positive (FP-RMS) or fusion-negative (FN-RMS), depending on whether a gene fusion involving PAX3 or PAX7 is prese
Microcalcifications are one feature of interest in mammography and breast tomosynthesis (BT). To achieve optimal conditions for detection of microcalcifications in BT imaging, different acquisition geometries should be evaluated. The purpose of this work was to investigate the influence of acquisition schemes with different angular ranges, projection distributions and dose distributions on the vis
Executive and attention dysfunctions are common in very preterm children. We studied their involuntary attention process by using behavioral measurements and auditory event-related potentials (AERP) with a distraction paradigm at age five years. The active task was to distinguish between two animal sounds. As an irrelevant feature the sounds were presented from frequent (standard) or infrequent (d
The standard procedure at mammography is to compress the breast in order to improve image quality, better separate tissue components and reduce absorbed dose to the breast. Traditionally, compression guidelines have been based on applied force, rather than actual thickness reduction. Structures such as the pectoral muscle are stiffer than breast tissue and if compressed along with it, as in the ML
A concept that lies at the heart of political rhetoric is that of ‘workfare’. The issue, however, is what types of arguments have been invoked to assert the value of the concept. During the 1960s and 1970s, extensive criticism emerged towards a working life that was said to hinder women’s emancipation; a working life that wasted resources and had a negative impact on the environment; a working lif
Popular Abstract in Swedish Fysiologisk integrering och morfologisk plasiticitet i stora klonala växter Många av våra vanligaste växter är klonala, dvs de kan producera avkommor utan sexuell befruktning. Hit räknas blåbär och lingon, många av våra vårväxter som tex. vitsippa och flera av våra värsta ogräs, som kvickrot och kirskål. En fördel som klonala växter har är att dotterskott som fortsätteClonal plants show a large variation in physiological integration, i.e. the translocation of resources among ramets within the clone. As resource transport is costly, we hypothesized that plants from poor sites should be more highly integrated than plants from rich sites and that plants would benefit if they were plastic in their degree of integration. Tracers were used to study the transport of w
Isaac Levi is more interested in inquiry and how it progresses than he is in metaphysics. Questions concerning the role of disposition predicates in inquiry are more central to him than those concerning the nature and reality of dispositions. It has not stopped him from giving me and others very useful metaphysical advice. Currently, where empirical metaphysics is in vogue, there is every reason t
Popular Abstract in SwedishMed tonsättaren och musikkritikern Moses Pergament (1893-1977) som biografiskt lod har syftet med denna studie varit att blottlägga och analysera föreställningar om "juden", modernism, nationalism och "ras" i det svenska samhället. Pergament föddes i Helsingfors och växte upp i ett svenskspråkigt judiskt-ortodoxt hem. Han kom till Sverige 1916 och blev svensk medborgare With the composer and music critic Moses Pergament (1893-1977) as a biographical prism, the purpose of this study has been to uncover ideas in Swedish society about nationalism, "the Jew", modernism and "race". Pergament was born in Helsinki, Finland, and grew up in a Swedish-speaking, Jewish orthodox home. He came to Sweden in 1916 and became a Swedish citizen in 1919. Along with his composing, P
Analysis of pollen and spore assemblages from both terrestrial and near-shore marine sediments in New Zealand reveal an instant and dramatic mass-kill of the land plants in close association with the Cretaceous-Tertiary boundary (KTB) event. The turnover in the palynoflora is followed by a recovery succession, the most prominent feature of which is an interval dominated by fern spores (fern spike)
a) The use of a solid phase reaction (silver silicate) for avoiding ortho ester formation in some difficult glycosyl donor/acceptor systems. Thus seven monodeoxygenated analogues of 2-(Trimethylsilyl)ethyl betha-lactoside were synthesiszed. Silver silcate was successfully used in betha 1-4 coupling of 2- and 3-deoxy glucosides to to acetobromogalactose. By similar means, the monodeoxylactosyl brom
Mitochondrial creatine kinase (Mi-CK) consists of octameric and dimeric molecules that are interconvertible. In the present study, the kinetic properties of purified chicken heart Mi-CK (Mi(b)-CK) dimers and octamers were investigated separately under highly controlled conditions. Gel-permeation chromatography was performed before and after kinetic measurements in order to clearly define the propo
Background and Aims: Radionuclide therapy is systemic, targeted radiotherapy. As such, we can apply the basic principles of radiobiology used in everyday practice in radiation oncology, as a means of tailoring the treatment to each patient and optimizing the balance between efficacy and toxicity. The most common type of radionuclide therapy used for the treatment of neuroendocrine tumors, is 177Lu
Background: Methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) and methylisothiazolinone (MI) are tested to detect contact allergy to these isothiazolinones. Objectives: To study if an aqueous patch test preparation with MCI and MI in a mix of 0.015% and 0.2%, respectively, detects more contact allergies than the commonly used preparations of MCI/MI in 0.02% aq. and MI in 0.2% aq. Methods:
Environmental change associated with urbanization is considered one of the major threats to biodiversity. Some species nevertheless seem to thrive in the urban areas, probably associated with selection for phenotypes that match urban habitats. Previous research defined different “copying styles” in distress behavior during the handling of birds. These behaviors vary along a continuum from “proacti
