Neuroblastoma and pre-B lymphoma cells share expression of key transcription factors but display tissue restricted target gene expression

Background: Transcription factors are frequently involved in the process of cellular transformation, and many malignancies are characterized by a distinct genetic event affecting a specific transcription factor. This probably reflects a tissue specific ability of transcription factors to contribute to the generation of cancer but very little is known about the precise mechanisms that governs these

Noninvasive ultrasound measurements of aortic intima-media thickness: Implications for in vivo study of aortic wall stress

Object: The abdominal aorta (AA) has a predilection for aneurysm formation. An etiologic factor may be underlying aortic wall stress. The purpose of this study was to examine whether the intima-media thickness (IMT) of the AA, as a surrogate to arterial wall thickness, can be measured noninvasively with satisfactory results to calculate circumferential wall stress, and to evaluate regional and gen

Frequency-Domain Analysis of Linear Time-Periodic Systems

In this paper, we study convergence of truncated representations of the frequency-response operator of a linear time-periodic system. The frequency-response operator is frequently called the harmonic transfer function. We introduce the concepts of input, output, and skew roll-off. These concepts are related to the decay rates of elements in the harmonic transfer function. A system with high input

A biosensor for the analysis of acetonitrile

A biosensor for monitoring acetonitrile was constructed. A mixed culture was taken from a degradation reactor and mounted on top of a Clark electrode. The amperometric biosensor was placed in a flow-through cell and integrated into a flow injection system. The metabolic response in terms of oxygen consumption was well correlated to the concentration of acetonitrile in standard solutions. However,

The great disappearing act: difficulties in doing "leadership"

We address ideas and talk about leadership in a research and development (R&D) company. The meaning that middle and senior managers ascribe to leadership is explored. We show how initial claims about leadership values and style tend to break down when managers are asked to expand on how they perceive their leadership and account for what they actually do in this respect. We raise strong doubts

Attosecond dynamics of electron wave packets in intense laser fields

We use a train of sub-200 attosecond extreme ultraviolet (XUV) pulses with energies just above the ionization threshold in argon to create a train of temporally localized electron wave packets. We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields. When the wave packets are born at the zero crossings o

Den första svenskspråkiga fabelsamlingen som konfessionaliseringsprojekt

Literary scholars have taken very little interest in the first collection of fables published in Swedish, Hundrade Esopi Fabler (A Hundred Fables of Aesop, 1603), compared to the interest shown its European counterparts. Based on research in the interdisciplinary field of ecclesiastical history, the present paper relates Hundrade Esopi Fabler to the concept of confessionalization, elaborated in re

Molecularly imprinted micro- and nano-particles by precipitation polymerization

Molecularly imprinted micro- and nano-particles can be conveniently prepd. using pptn. polymn. method. By controlling the initial reaction compn., the resulting polymer particles may be obtained as uniform beads that display favorable binding characteristics. Incorporation of a novel reporter element resulted in an imprinted scintillation polymer that displayed an enhanced signaling

Fusion enligt ABl 14:8 - en skatte-, bolags, och redovisningsrättslig studie

Summary in English This dissertation bears the title "Fusions as defined by the Swedish Companies Act 'ABL' of 1975 (14:8) - a study of tax, corporation and accountancy legislation". The dissertation constitutes a study of fusions from the perspective of (as the title suggests) taxation, corporation and accountancy legislation. The Swedish Companies Act (ABL) includes rules concerning two forms o

Profiles of occupational engagement in persons with schizophrenia, POES: Development of a new instrument based on time diaries

Previous time-use research suggests that it is highly relevant for an occupational therapist to estimate time use and occupational engagement in order to understand some of the determinants of wellbeing for people with schizophrenia. This article describes the development and the testing of the psychometric properties of an instrument, Profiles of Occupational Engagement in people with Schizophren

Simple Feedback Control and Mode Switching Strategies for GDI Engines

A novel approach to the control of a GDI engine is presented. The controller consists of a combination of sub-controllers, where torque feedback is a central part. The sub-controllers are with a few exceptions designed using simple linear feedback and feedforward control design methods. Special mode switch strategies are used to minimize the torque bumps during combustion mode changes. The control

The brief study aims to identify the genesis of the first dramatic protagonist Mihail Sebastian imagined, both the autobiographical and the literary earlier experiences and expressions of his playwriting philosophy of the evasion, a philosophy that is to be regarded as a prototype for his future drama. For this a rather exhaustive synthesis of the critical references is required as well as a minut
