The theme of the Internet and the public sphere now has a permanent place on research agendas and in intellectual inquiry; it is entering the mainstream of Political communication studies. The first part of this presentation briefly pulls together key elements in the public sphere perspective, underscoring three main analytic dimensions: the structural, the representational, and the interactional.
Islet beta cell adaptation to dexamethasone-induced insulin resistance was characterized with respect to glucose-stimulated insulin secretion and islet innervation. Male Sprague-Dawley rats were injected daily with dexamethasone (2 mg/kg for 12 days), which resulted in hyperinsulinemia and hyperglycemia compared with controls (which were injected with sodium chloride). Insulin secretion was charac
The A (1)Sigma(+) potential energy curve of AgH is studied by means of the second-order multistate multireference perturbation theory including the spin-orbit and relativistic effects. The anomalous behavior of the vibrational energy levels observed in experiment is reproduced well by theory. An analysis of the A (1)Sigma(+) wave function shows that at the internuclear distance of 4-6 Angstrom, a
The present study of spectra of twelve metal-rich cool dwarf stars, carefully selected in order to cover a range of temperatures ( K), is a follow up on Feltzing & Gustafsson (1998) with the aim to understand the apparent over-ionization and anomalous elemental abundances found by them for the K dwarf stars in their sample. Our method of analysis employs synthetic spectra of the full spectrum
Popular Abstract in Swedish Patienternas perspektiv på att vara IVA patient i relation till IVA syndrom/delirium Att intensivvårdspatienter (IVA patienter) som vårdats med respirator inte minns sin tid på IVA är en myt. Det finns patienter som inte minns , men de flesta patienterna i avhandlingen minns från uppvaknandet och borttagandet av droger och respiratorn sin tid de närmaste dagarna däreftWhen a person becomes critically ill, injured and/or undergoes major surgery and requires intensive care, a complex dilemma can arise. The condition of the illness, the specific caring situation and the environment lead to significant changes and effects in the senses and perceptional abilities. Under these conditions some patients can develop symptoms of the Intensive Care Unit syndrome/delirium.
I will start out with an overview of common assumptions on the impact of free trade on the environment – assumptions which, very much like the first part of Lamy’s statement, are all-encompassing and deterministic. From there, I will narrow down the scope of examination to specific and immediate hardware-to-hardware impacts: akin to the second part of the above statement, the emphasis shall be put
The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. DNA, proteins, copolymers. One of the most robust computer simulation techniques for free energy estimation is an
Three pyralid moths, the Mediterranean flour moth (Ephestia kuehniella), the almond moth (Ephestia cautella) and the Indian meal moth (Plodia interpunctella), infest food products all over the world and cause severe problems in factories, shops and households. For health and environmentalreasons chemical control becomes more and more restricted. We here present some promising results offering effi
Acute lymphoblastic leukemia (ALL) is the most widespread type of cancer, as well as the most frequent leukemia in children. Malignant ALL cells originate from normal T lymphocytes or B cells that are blocked at immature stages of differentiation. Since T cell lineage derived ALL in children is associated with various unfavorable features, it is no surprise that childhood T lineage ALL have been r
Fetal experience forms the basis for postnatal life. This relationship may be obvious in the newborn infant, although it is sometimes not apparent until later in development. One fetal condition with known implications for later life is intrauterine growth restriction (IUGR), which ranges from being an important factor in perinatal mortality to affecting morbidity in adulthood. The process of grow
Popular Abstract in Swedish Neuroblastom, när utvecklingen går fel Neuroblastom är en tumörsjukdom som drabbar små barn och i Sverige diagnosticeras ungefär 14 barn med neuroblastom varje år. Neuroblastomtumörerna utvecklas under anläggningen av det sympatiska nervsystemet, som är en del av det icke-viljestyrda nervsystemet och har till uppgift att anpassa kroppens svar på stress och fara genom at
Abstract This paper offers a new description and explanation of morphological agreement, argument-verb agreement in particular. The hypothesis explored is that argument-verb agreement is directly related to selection of arguments (s-selection), i.e. s-selectional features are in fact ф-features ([PERSON, NUMBER(, GENDER)], and that morphological argument-verb agreement mirrors this relation. Call
Parametric linkage analysis is usually used to find chromosomal regions linked to a disease (phenotype) that is described with a specific genetic model. This is done by investigating the relations between the disease and genetic markers, that is, well-characterized loci of known position with a clear Mendelian mode of inheritance. Assume we have found an interesting region on a chromosome that we
Recent findings in adult rodents have provided evidence for the formation of new striatal neurons from subventricular zone (SVZ) precursors following stroke. Little is known about which factors determine the magnitude of striatal neurogenesis in the damaged brain. Here we studied striatal neurogenesis following an excitotoxic lesion to the adult rat striatum induced by intrastriatal quinolinic aci
Glucose-evoked insulin secretion exhibits a biphasic time course and is associated with accelerated intracellular granule movement. We combined live confocal imaging of EGFP-labelled insulin granules with capacitance measurements of exocytosis in clonal INS-1 cells to explore the relation between distinct random and directed modes of insulin granule movement, as well as exocytotic capacity. Reduci
Stereoselectivity has been known to play a role in drug action for 100 years or more. Nevertheless, chiral drugs have been developed and used as racemates, neglecting the fact that they comprise mixtures of two or more compounds which may have quite different pharmacological properties. A very limited access to pure enantiomers in the past has been responsible for this unsatisfactory state of affa
Purpose To investigate whether previously observed correlations between tumor karyotype and risk of metastases could be reproduced in an independent set of high-grade soft tissue sarcomas (STSs). Patients and Methods In a previous study on high-grade STSs with clonal chromosome aberrations, we identified a number of cytogenetic variables, besides tumor grade and size, that were associated with sig
To elucidate the organization of the ferret spinocervicothalamic pathway (SCTP), we examined the lateral cervical nucleus (LCN) and the termination of the cervicothalamic tract (CTY) in this species. In thionin-stained sections, the ferret LCN appeared as an easily delineated column of cells in the dorsolateral funiculus from about mid-C3 to the rostral end of C1, with most cells located in the C1
In the kindling model of epilepsy, repeated electrical stimulations lead to progressive and permanent intensification of seizure activity. We find that the development of amygdala kindling is markedly retarded in mice heterozygous for a deletion of the neurotrophin-3 (NT-3) gene (NT-3+/- mice). These mice did not reach the fully kindled state (3rd grade 5 seizure) until after 28 +/- 4 days of stim
