A polyacrylamide gel crosslinked with allyl-b-cyclodextrin can be used repeatedly for several weeks for the separation of DNA fragments, since bubbles are not generated during a run. Allyl-b-cyclodextrin can easily be synthesized in one step from allylglycidylether and b-cyclodextrin. The plate numbers for DNA fragments, up to about 1500 bp, are high: for the 21 separation of pBR322/HaeIII fragmen
BACKGROUND: Local tumour destruction has been shown to give rise to changes in immunocompetent cells. The aim of this study was to describe the effect of interstitial laser thermotherapy (ILT) of breast carcinoma in the tumour and in regional lymph nodes. METHODS: Seventeen women that underwent radical surgical excision after non-radical ILT were studied. ILT was performed at a steady-state temper
Choline acetyltransferase (ChAT) is the key-enzyme for acetylcholine (ACh) synthesis and constitutes a reliable marker for the integrity of cholinergic neurons. Cortical ChAT activity is decreased in the brain of patients suffering from Alzheimer's and Parkinson's diseases. The standard method used to measure the activity of ChAT enzyme relies on a very sensitive radiometric assay but can only be
Popular Abstract in Swedish Olika morfologiska former i olika språk antas bero på gemensamma kognitiva funktioner och semantiska egenskaper. En övergripande term för sådana semantiska egenskaper är transitivitet. Transitivitet yttrar sig bl.a. i aspekt hos verbet och bestämdhet hos objektet. En avgörande kognitiv funktion är för- och bakgrundsstruktur av information. Detta testas här empiriskt i (This work assumes that various linguistic forms in different languages are related to common cognitive functions and semantic properties. A cognitive function - presumably universal - is information transmission. The notion of interest is transitivity, which contains a set of semantic properties such as agentivity, dynamism, affectedness, boundedness and givenness, and the explicit forms are verb
The ability to understand and communicate about the actions of others is a fundamental aspect of our daily activity. How can we talk about what others are doing? What qualities do different actions have such that they cause us to see them as being different or similar? What is the connection between what we see and the development of concepts and words or expressions for the things that we see? To
The duration of P fertiliser in acid forest soil was investigated in a Norway spruce (Picea abies Karst.) forest in southcentral Sweden. The fertilisation of the soil started in 1967, but no P has been applied since 1988. The N fertilisation is still continuing. Totally, 300 kg P per hectare, as superphosphate, and/or 1090 kg N per hectare, as ammonium nitrate, was applied. Concentrations of both
This paper describes an extensive propagation channel measurement campaign in a warehouse environment for line-of-sight (LOS) and nonline-of-sight (NLOS) scenarios. The measurement setup employs a vector network analyzer operating in the 2-8-GHz frequency band combined with an 8×8 virtual multiple-input multiple-output (MIMO) antenna array. We develop a comprehensive statistical propagation channe
In this article, gas-phase advanced oxidation, a new method for pollution control building on the photo-oxidation and particle formation chemistry occurring in the atmosphere, is introduced and characterized. The process uses ozone and UV-C light to produce in situ radicals to oxidize pollution, generating particles that are removed by a filter; ozone is removed using a MnO2 honeycomb catalyst. Th
The Benguela Upwelling System (BUS), located between 30 and 20°S, is one of the fundamental high-productivity systems of the world ocean. The BUS has previously been studied in terms of primary productivity and ecology over glacial-interglacial timescales; however, the response and coupling with the benthic environment have received little attention. Here, for the first time, we present a high-res
Realistic propagation modeling requires a detailed understanding and characterization of the radio channel properties. This paper is based on channel sounder measurements with 1 GHz bandwidth at a carrier frequency of 5.7 GHz and particular tracking methods. We present statistical models for the number of, birth rate, lifetime, excess delay and relative Doppler frequency of individual multipath co
Sense of Coherence (SOC) measures an individual's positive, or salutogenic, orientation toward her/his capacities, environment, future, and life. SOC comprises three factors: comprehensibility (the sense of one's own life as ordered and understandable); manageability (the perception of available resources and skills to manage stressors); and meaningfulness (the overall sense that life is filled wi
Ljus består av elektromagnetiska vågor som pulserar genom universum med olika frekvenser. Vanligt ljus, som det som kommer från solen och från våra lampor, innehåller ett spektrum av många olika frekvenser. De olika vågornas toppar och dalar svänger inte heller i takt, utan är förskjutna i förhållande till varandra. I laserljus däremot, svänger alla vågor samtidigt upp och ner och med samma frekveThis thesis adresses modeling of quantum cascade lasers using non-equilibrium Green’s functions. Focus lies on the quantitative modeling of the gain when the systems are exposed to strong laser fields, as under realistic opertional conditions. In the first part, an introduction to the general concepts is provided, together with a discussion on approximate analytic expressions. The second part cons
The distribution of neuronal nitric oxide synthase (NOS) immunoreactivity was examined in rat and rabbit retinas and was compared with the distribution of nicotinamide adenine dinucleotide phosphate (NADPH)-diaphorase reactivity and vasoactive intestinal peptide (VIP) immunoreactivity. An antibody raised against a C-terminal fragment of a cloned rat cerebellar NOS was used to localise NOS immunore
Introduction: Trismus is a treatment-related late side effect in patients treated for cancer in the head and neck region (HNC). The condition can have a considerable negative impact on nutrition, dental hygiene, ability to speak and quality of life. We have previously studied trismus within the frame of a randomized phase 3 study of HNC patients treated with mainly three-dimensional (3D) conformal
The illegal use of pharmacologically active compounds for growth promotion in food-producing species poses risks for consumer health and animal welfare. Surveillance relies on the quantification of drug residues in animal fluids or tissues, but the efficacy can be negatively affected due to undetectable residual concentrations in biological matrices. Consequently, techniques focusing on the indire
All thoracic limbs of Hutchinsoniella except for the ninth contain entirely of podocytes. At the periphery of the gland, each podocyte with the investing basal lamina; centrally, there is no conspicuous podocytes, either in compact glands or in a more diffuse arrangement, decapods, mysids, and isopods, and perhaps occur in other crustaceans known to filter hemolymph and to pinocytotically extract
Disinhibition is an important symptom in neurodegenerative diseases. However, the clinico- anatomical underpinnings remain controversial. We explored the anatomical correlates of disinhibition in neurodegenerative disease using the perspective of grey and white matter imaging. Disinhibition was assessed with a neuropsychological test and a caregiver information- based clinical rating scale in 21 p
