Neural Progenitor Cells in malignancy and injury of the brain. A Trojan Horse fro gliomas?

Popular Abstract in Swedish Gliom är en familj av hjärntumörer som är graderade beroende på hur snabbt och på vilket sätt de växer. Grad IV även kallad glioblastoma multiforme, är den mest elakartade av dessa. Patienter har en medelöverlevnadsprognos på ca 12 månader med behandling, såsom kirurgi, kemo- och strålningsterapi. Tumörerna är heterogena, vilket innebär att celler har flera typer av mutGliomas are neoplasms arising in the central nervous system (CNS), and constitute the most common primary brain tumor. They are classified depending on the grade and morphology, from grade I, pilocytic astrocytoma, to grade IV, glioblastoma multiforme (GBM). Glioblastomas constitute a great challenge in treatment due to their disseminating nature. Classical treatments such as surgery, radiation th

Anaerobic batch co-digestion of sisal pulp and fish wastes

Co-digestion of various wastes has been shown to improve the digestibility of the materials and biogas yield. Batchwise digestion of sisal pulp and fish waste was studied both with the wastes separately and with mixtures in various proportions. While the highest methane yields from sisal pulp and fish waste alone were 0.32 and 0.39 m(3) CH4/kg volatile solids (VS), respectively, at total solid (TS

Formulation and in vitro/in vivo evaluation of combining DNA repair and immune enhancing nutritional supplements

Combining nutritional supplements to achieve synergistic benefit is a common practice in the nutraceutical industry. However, establishing. added health benefit from a combination of natural ingredients is often assumed, untested and without regard to the principle of metabolic competition between the active components. Here, we report on the combination of a cat's claw water extract (C-Med-100, c

Factors controlling large scale variations in methane emissions from wetlands

[1] Global wetlands are, at estimate ranging 115-237 Tg CH4/yr, the largest single atmospheric source of the greenhouse gas methane (CH4). We present a dataset on CH4 flux rates totaling 12 measurement years at sites from Greenland, Iceland, Scandinavia and Siberia. We find that temperature and microbial substrate availability (expressed as the organic acid concentration in peat water) combined ex

Development of Simultaneous Saccharification and Fermentation for Production of Ethanol from Softwood

This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. In the first case, part of the stillage stream after distillation was recycled and in th

Neuronal replacement from endogenous precursors in the adult brain after stroke.

In the adult brain, new neurons are continuously generated in the subventricular zone and dentate gyrus, but it is unknown whether these neurons can replace those lost following damage or disease. Here we show that stroke, caused by transient middle cerebral artery occlusion in adult rats, leads to a marked increase of cell proliferation in the subventricular zone. Stroke-generated new neurons, as

Low birth weight infants and Calmette-Guerin bacillus vaccination at birth: community study from Guinea-Bissau

BACKGROUND: In developing countries, low birth weight (LBW) children are often not vaccinated with Calmette-Guerin bacillus (BCG) at birth. Recent studies have suggested that BCG may have a nonspecific beneficial effect on infant mortality. We evaluated the consequences of not vaccinating LBW children at birth in Guinea-Bissau. METHODS: Between 1989 and 1999, 7138 children born at the central hosp

Bat flight generates complex aerodynamic tracks

The flapping flight of animals generates an aerodynamic footprint as a time-varying vortex wake in which the rate of momentum change represents the aerodynamic force. We showed that the wakes of a small bat species differ from those of birds in some important respects. In our bats, each wing generated its own vortex loop. Also, at moderate and high flight speeds, the circulation on the outer ( han

Creep Recovery and Elastic Modulus of High Performance Concrete

This article outlines an experimental and numerical study on short-term and long-term creep recovery in High Performance Concrete. About 200 cylinders and 800 cubes were tested. The ambient climate was held constant at 20 °C and 55% relative humidity. Results and analyses are presented as regards short-term and long-term creep recovery with some related properties. The creep deformations are separ

Increased incidence of cardiovascular disease in patients with rheumatoid arthritis: results from a community based study

Objective: To investigate the first-ever incidence of acute myocardial infarction and stroke in a community based RA cohort compared with the general population. Methods: The RA cohort consisted of all patients in a local RA register in Malmo, Sweden (n = 1022). The patients were recruited from private and hospital based rheumatology practices, and made up the absolute majority of patients with RA

Sagali and the Kula : A Regional Systems Analysis of the Massim

This thesis is concerned with developing a consistent regional perspective on the Massim peoples of southeastern Papua New Guinea, a task largely neglected by earlier anthropological studies, it is claimed, or, when sometimes attempted, unsuccessfully accomplished for a number of reasons, both methodological and theoretical. The author uses a comparative approach for investigating a selection of

Skoldaghem: Ett alternativ för elever i behov av särskilt stöd

Popular Abstract in Swedish Studien handlar om tio elever i behov av särskilt stöd. Den förhärskande tanken inom det svenska utbildningsväsendet är att elever med funktionshinder ska integreras i den vanliga skolan. Undantag får emellertid göras och eleverna kan t.ex. få sin skolgång på ett skoldaghem. Det främsta syftet med föreliggande studie är att undersöka hur sju elever med skolgång på skolThis thesis concerns ten pupils in need of special support. The overriding principle governing the Swedish educational system today is that pupils with functional difficulties should be integrated into ordinary schools, but exceptions may be made and the pupils can attend a special day-school. The primary aim of the present thesis is to study the progress of seven students, attending special day-s

UAMSHO: A Theological Study of the Proclamation of the Revival Movement within the Evangelical Lutheran Church in Tanzania

This thesis presents a theological study of the revival (Uamsho) movement within the Evangelical Lutheran Church in Tanzania (ELCT). This movement is part of the East African Revival Movement that began during the late 1920's within the Protestant churches in Rwanda, after which it spread to Uganda, Kenya, and Tanzania. The introductory chapter begins with a presentation of characteristic feature
