Recently, we and others reported a recurrent t(7;12)(q36;p13) found in myeloid malignancies in children < or =18 months of age and associated with a poor prognosis. Fluorescence in situ hybridization studies mapped the 12p13 breakpoint to the first intron of ETV6 and narrowed down the region of 7q36 involved. By using the sequences made public recently by the Human Genome Project, two candidate ge
The aim of this study was to characterize polypeptide components of the capture net spun by trichopteran larvae Hydropsyche slossonae (Banks) (Trichoptera: Hydropsychidae). Thirty-one polypeptide bands were identified by SDS - polyacrylamide gel electrophoresis (SDS-PAGE) from extracted net material, with molecular weights ranging from 8500 to 179 000. Comparison with published data on Bombyx mori
Rapporten innehåller sex från varandra fristående avsnitt som behandlar olika flödesproblem och styr- och reglertekniska frågor inom solvämetekniken. Ämnen som berörs är bl a flödesproblem i seriekopplade kollektorer, reglering av solkollektortemperatur och styrsystemets betydelse för insamlad solenergi.
Popular Abstract in Swedish Denna avhandling behandlar tre centrala områden i finansiell ekonomi i allmänhet och portföljvalsteori i synnerhet: riskmåttet, estimeringsrisk och tidsdiversifiering. Avhandlingen består av fem kapitel varav ett är ett kort introduktionskapitel. De första två kapitlen behandlar ett alternativt mått på risk, lower partial moment (LPM). Detta alternativa mått behandlar eThis thesis is devoted to the analysis of three important issues in financial economics in general and portfolio selection in particular: the risk measure, estimation risk and time diversification. Besides a short introductory chapter the thesis consists of four empirical essays. In the second chapter, the effect of estimation risk on the efficient frontier in the lower partial moment framework is
Models of Parkinson's disease (PD) based on selective neuronal death have been used to study pathogenic mechanisms underlying nigral cell death and in some instances to develop symptomatic therapies. For validation of putative neuroprotectants, a model is desirable in which the events leading to neurodegeneration replicate those occurring in the disease. We developed a human in vitro model of PD b
This paper discusses the reasons for the recent success of Swedish popular music abroad. It departs from recent Swedish economic reports showing that the increase in exports of Swedish music per capita is comparable to, and even exceeds, those of the United Kingdom and the United States, and presents theories about why Swedish popular music exports have grown during the last years. A method of mu
The use of short interfering RNAs (siRNA) for selective suppression of protein production has rapidly become a commonly used technique for transient modulation of protein levels. In the present paper, we investigate whether introduction of platinated bases in the sense strand can be used to modulate the efficacy of siRNAs. Four different siRNAs were studied, all targeting the initial AU-rich 3' UT
We studied the association between alexithymia (20-item Toronto Alexithymia Scale, TAS-20) and obesity, and also assessed the construct validity of the TAS-20 in terms of personality dimensions in obese patients. The TAS-20 and its subscales were analysed for their correlations with the NEO Personality Inventory - Revised (NEO PI-R) in an obese sample of 259 patients. Obesity was associated with h
The mechanistic implications of the kinetic behaviour of a fusion protein of mitochondrial malate dehydrogenase and citrate synthase have been reanalysed in view of predictions based on experimentally determined kinetic parameter values for the dehydrogenase and synthase activities of the protein. The results show that the time-course of citrate formation from malate in the coupled reaction cataly
In flowering plants, the onset and duration of female receptivity vary among species. In several species the receptive structures wilt upon pollination. Here we explore the hypothesis that postpollination wilting may be influenced by pollen and serve as a general means to secure paternity of the pollen donor at the expense of female fitness. Taking a game-theoretical approach, we examine the poten
In a road simulator study, a significant source of sub-micrometer fine particles produced by the road-tire interface was observed. Since the particle size distribution and source strength is dependent on the type of tire used, it is likely that these particles largely originate from the tires, and not the road pavement. The particles consisted most likely of mineral oils from the softening filler
The purposes of this study were: (i) to determine the test-retest reliability of isokinetic ankle dorsiflexor strength measurements in young healthy adults using the Biodex dynamometer, and (ii) to examine several statistical measures for the interpretation of reliability. Thirty men and women (mean age 23 +/- 3 years) performed three maximal concentric contractions at 30 degrees/s, 60 degrees/s,
Popular Abstract in Swedish Kardiovaskulär sjukdom karaktäriseras av lipid accumulering och inflammation i artärerna. Sjukdomen startar tidigt med att monocyter vandrar ut i kärlväggen där de differentierar till makrofager, tar upp modifierade lipoproteiner och utvecklas till skumceller. En samtidig inflammation bidrar till att fler celler och mer lipider ansamlas och ett aterosklerotiskt plack böCardiovascular disease (CVD) is characterized by lipid accumulation and inflammation in arteries. The disease starts early in life with migration of monocytes into the arterial wall where they engulf entrapped lipoproteins and become macrophage foam cell. A simultaneous inflammatory response further enhances lipid and cell accumulation at sites of lesion development, resulting in progression of at
