Methods for Control of Liquid Slosh

Horizontal movement of liquid containers is a common operation in an industrial packaging machine. During the movement the acceleration of the container induces motion of the liquid within the container, this is referred to as liquid slosh or liquid vibration. If there is too much slosh the liquid might wet the sealing surfaces of the container and even contaminate the machine. There is no measure

Integration of Molecular Biology and Morphology in Effusions with Focus on in situ Detection of Telomerase and its Components

Popular Abstract in Swedish Den viktigaste uppgiften inom den kliniska cytologin är att påvisa cancerceller i olika typer av cellprover. Många olika cancertumörer sprider sig till lungsäcken och bukhålan och ger då ofta upphov till vätska (exsudat) som innehåller cancerceller. Ofta kan cancerdiagnosen ställas på grundval av cellernas utseende men detta är inte alltid möjligt, eftersom cancercellerClinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. It is the most promising universal indicator of malignancy and the project focuses o

Copper-dependent co-internalization of the prion protein and glypican-1.

Heparan sulfate chains have been found to be associated with amyloid deposits in a number of diseases including transmissible spongiform encephalopathies. Diverse lines of evidence have linked proteoglycans and their glycosaminoglycan chains, and especially heparan sulfate, to the metabolism of the prion protein isoforms. Glypicans are a family of glycosylphosphatidylinositol-anchored, heparan sul

Novel endogenous mechanisms of complement regulation - A delicate balance

In this thesis, the biochemical mechanisms for complement activation by endogenous proteins are explored. The short leucine-rich repeat proteins (SLRPs) help organise extracellular matrices. We found that several SLRPs bind C1q and of these, fibromodulin and osteoadherin trigger complement. These two glycoproteins also bind the complement regulator factor H (FH). Our findings may have implication

Human alpha-lactalbumin made lethal to tumor cells (HAMLET) kills human glioblastoma cells in brain xenografts by an apoptosis-like mechanism and prolongs survival.

Malignant brain tumors present a major therapeutic challenge because no selective or efficient treatment is available. Here, we demonstrate that intratumoral administration of human α-lactalbumin made lethal to tumor cells (HAMLET) prolongs survival in a human glioblastoma (GBM) xenograft model, by selective induction of tumor cell apoptosis. HAMLET is a protein-lipid complex that is formed from α

Functional Recovery after Experimental Stroke in Mice- Involvement of Enriched Environment, BDNF and Cell Genesis

Popular Abstract in Swedish Stroke (slaganfall) orsakas av en propp i hjärnan eller av en hjärnblödning, som hindrar blodflödet till hjärnan. Eftersom hjärnan är beroende av konstant tillförsel av syre och glykos från blodet för sin funktion, leder en blockering av blodflödet till hjärnskador. Stroke är den tredje vanligaste dödsorsaken i västvärlden och den vanligatse orsaken till handikapp hos vStroke is caused by an obstruction of blood flow to a part of the brain, resulting in brain damage. Stroke is the third most common cause of death in the industrialized world, and the primary cause of adult-onset disability. There is a spontaneous recovery of function after stroke but several factors, such as the environment can influence the speed and extent of this recovery. This thesis deals wi

On the characterization of ultra-precise X-ray optical components: advances and challenges in ex situ metrology.

To fully exploit the ultimate source properties of the next-generation light sources, such as free-electron lasers (FELs) and diffraction-limited storage rings (DLSRs), the quality requirements for gratings and reflective synchrotron optics, especially mirrors, have significantly increased. These coherence-preserving optical components for high-brightness sources will feature nanoscopic shape accu

PECC-Factor structure and findings in three longitudinal cohorts of patients with schizophrenia

Background: Symptom control by drug treatment is the most important task in routine clinical care of patients with schizophrenia. Structured assessment methods are needed in this task but not used much. The US-developed Positive and Negative Syndrome Scale (PANSS) is a standard tool for symptom assessment. The Psychosis Evaluation tool for Common use by Caregivers (PECC) was constructed in Europe

Expression of Epstein-Barr Virus-Encoded LMP1 and hTERT Extends the Life Span and Immortalizes Primary Cultures of Nasopharyngeal Epithelial Cells

Cell immortalization is regarded as an early and pre-requisite step in tumor development. Defining the specific genetic events involved in cell immortalization may provide insights into the early events of carcinogenesis. Nasopharyngeal carcinoma is common among the Southern Chinese population. Epstein-Barr virus (EBV) infection is associated closely with nasopharyngeal carcinoma. The involvement

Crystal phase control in GaAs nanowires: opposing trends in the Ga- and As-limited growth regimes

Here we demonstrate the existence of two distinct regimes for tuning crystal structure in GaAs nanowires from zinc blende to wurtzite using a single process parameter: V/III-ratio, or variation of the group V precursor flow. Extensive previous studies have shown that crystal structure is sensitive to V/III-ratio, and even that it is possible to change structure entirely using this single parameter

Interface Controlled Oxidation States in Layered Cobalt Oxide Nanoislands on Gold

Layered cobalt oxides have been shown to be highly active catalysts for the oxygen evolution reaction (OER; half of the catalytic "water splitting" reaction), particularly when promoted with gold. However, the surface chemistry of cobalt oxides and in particular the nature of the synergistic effect of gold contact are only understood on a rudimentary level, which at present prevents further explor
