Widening the configuration management perspective

A metainformatics symposium provides an excellent opportunity to explore, discuss and investigate how configuration management techniques and principles can be expanded into new fields and how it itself can incorporate techniques from other fields

Behavioural repertory of cats without cerebral cortex from infancy

Bilateral removal of the cerebral cortex was made in cats neonatally. Spontaneous and imposed behaviour was studied while they were growing up and after they had become adult. Special emphasis was put on the utilization of visual cues and on learning. The cats ate, drank and groomed themselves adequately. Adequate maternal and female sexual behaviour was observed. They utilized the visual and hapt

Islet G protein-coupled receptors as potential targets for treatment of type 2 diabetes.

Islet dysfunction - characterized by a combination of defective insulin secretion, inappropriately high glucagon secretion and reduced beta-cell mass - has a central role in the pathophysiology of type 2 diabetes. Several G protein-coupled receptors (GPCRs) expressed in islet beta-cells are known to be involved in the regulation of islet function, and therefore are potential therapeutic targets. T

Prevention of Abdominal Adhesions - Present State and What's beyond the Horizon?

Intra-abdominal adhesions are normally found after most surgical procedures. Many of the adhesions are asymptomatic, but in about 5% they will lead to readmission due to adhesion-related disorders, such as small bowel obstruction, pelvic pain and infertility. This review discusses possible ways to prevent abdominal adhesions and provides an update as comes to where we stand today in research regar

Hepatic and extrahepatic malignancies in autoimmune hepatitis. A long-term follow-up in 473 Swedish patients

Background/Aims: Autoimmune Hepatitis (AIH) is a liver disease which may lead to liver cirrhosis. Cirrhosis is a well-known risk factor for hepatocellular cancer. Lymphoma is a disease, where immune modulating drugs as well as the autoimmune disease itself may contribute to the elevated risk. The aim was to investigate the risks of malignancies in a large cohort of AIH patients. Methods: Four hund

Tuning the polymer release from hydrophilic matrix tablets by mixing short and long matrix polymers

In this work a rotating disc method was developed for studying the dissolution process of "bimodal" polymer tablets, whose dissolution rates have been tuned by mixing low-molecular weight and high-molecular weight samples of poly(ethylene oxide) in various proportions. The tablets were prepared along different routes, by mixing the polymer fractions as powders or by mixing on a molecular level so

Process development and characterization of antisticking layers on nickel-based stamps designed for nanoimprint lithography

Thin films of different derivatives of fluorinated alkyl phosphoric acids have been deposited from aqueous solutions onto surfaces of oxidized polycrystalline nickel stamps. which are commonly used in several industrial applications of nanoimprint lithography (NIL). The films have been established in order to increase the antiadhesion tendencies at the stamp polymer interface. Thicknesses, chemica

Dynamic distribution of endoplasmic reticulum in hippocampal neuron dendritic spines

The role of the endoplasmic reticulum (ER) localized in dendritic spines has become a subject of intense interest because of its potential functions in local protein synthesis and signal transduction. Although it is recognized from electron microscopic studies that not all spines contain ER, little is know of its dynamic regulation or turnover. Here, we report a surprising degree of turnover of ER

In vitro self-assembly of the light harvesting pigment-protein LH2 revealed by ultrafast spectroscopy and electron microscopy

Controlled ensemble formation of protein-surfactant systems provides a fundamental concept for the realization of nanoscale devices with self-organizing capability. In this context, spectroscopic monitoring of pigment-containing proteins yields detailed structural information. Here we have studied the association behavior of the bacterial light-harvesting protein LH2 from Rhodobacter spheroides in

Modelling tracer transport by a cumulus ensemble: lateral boundary conditions and large-scale ascent

The vertical transport of tracers by a cumulus ensemble at the TOGA-COARE site is modelled during a 7 day episode using 2-D and 3-D cloud-resolving setups of the Weather Research and Forecast (WRF) model. Lateral boundary conditions (LBC) for tracers, water vapour, and wind are specified and the horizontal advection of trace gases across the lateral domain boundaries is considered. Furthermore, th

N-methyl-D-aspartate receptor-mediated increase of neurogenesis in adult rat dentate gyrus following stroke

Neurogenesis in the adult rat dentate gyrus was studied following focal ischemic insults produced by middle cerebral artery occlusion (MCAO). Animals were subjected to either 30 min of MCAO, which causes damage confined to the striatum, or 2 h of MCAO, which leads to both striatal and cortical infarction. When compared to sham-operated rats, MCAO-rats showed a marked increase of the number of cell

Apolipoprotein D is involved in the mechanisms regulating protection from oxidative stress

Many nervous system pathologies are associated with increased levels of apolipoprotein D (ApoD), a lipocalin also expressed during normal development and aging. An ApoD homologous gene in Drosophila, Glial Lazarillo, regulates resistance to stress, and neurodegeneration in the aging brain. Here we study for the first time the protective potential of ApoD in a vertebrate model organism. Loss of mou

Sertindole: efficacy and safety in schizophrenia

Sertindole is an antipsychotic drug with affinity for dopamine D, serotonin 5-HT2A and 5-HT2C, and alpha(1)-adrenoreceptors. Preclinical studies suggest that sertindole acts preferentially on limbic and cortical dopaminergic neurons and clinical trials have confirmed that sertindole is effective at a low cloparnine D-2 occupancy level. The active substance has a long half-life. Oral administration

Nontangential limits in Pt(µ)-spaces and the index of invariant subgroups

Abstract Let μ be a finite positive measure on the closed disk D¯ in the complex plane, let 1 ≤ t < ∞, and let Pt(μ) denote the closure of the analytic polynomials in Lt(μ). We suppose that D is the set of analytic bounded point evaluations for Pt(μ), and that Pt(μ) contains no nontrivial characteristic functions. It is then known that the restriction of μ to ∂D must be of the form h|dz|. W

Diffuse axonal damage, myelin impairment, astrocytosis and inflammatory response following microinjections of NMDA into the rat striatum

White matter damage and inflammatory response are important secondary outcomes after acute neural disorders. Nevertheless, a few studies addressed the temporal outcomes of these pathological events using non-traumatic models of acute brain injury. In the present study, we describe acute inflammatory response and white matter neuropathology between 1 and 7 days after acute excitotoxic striatal dama

Human immunodeficiency virus (HIV)-2-specific T lymphocyte proliferative responses in HIV-2-infected and in HIV-2-exposed but uninfected individuals in Guinea-Bissau

Human immunodeficiency virus (HIV)-2-specific T lymphocyte proliferative responses were determined in cultures of peripheral blood mononuclear cells from HIV-2-exposed uninfected individuals, HIV-2-infected individuals and HIV-negative controls in Guinea-Bissau. Increased HIV-2-specific T lymphocyte proliferative responses were detected in both groups compared to HIV-negative controls (healthy HIV
