<i>Background</i> - Many cases of acute lymphoblastic leukemia (ALL) carry visible acquired chromosomal changes of pathogenetic, diagnostic, and prognostic importance. Nevertheless, from one-fourth to half of newly diagnosed ALL patients have no visible chromosomal changes detectable by G-banding analysis at diagnosis. The introduction of powerful molecular methodologies has shown that many ...

The aim of this study was to prepare and optimize a novel type of in situ gel-forming solid dosage form (gfSDF) to be used in the treatment of mucosal/skin ulcerations. For this purpose, a simple but reliable syringe-based hot melt/moulding method was employed. Chloramphenicol (antibiotic) and ibuprofen (anti-inflammatory) were chosen as model active pharmaceutical ingredients (APIs) to be loaded ...

Acute heart failure (AHF) is a disease with a mortality ranging from 5 to 40% depending on severity, despite modern revascularization techniques after acute myocardial thromboembolism. In this thesis we have investigated two new concepts of treating AHF. In paper 1 we investigated the combination of dobutamine and ivabradine (D+I) in a porcine model of stunning AHF. Ivabradine attenuated the ...

Liposomes are lipid-based systems which have the ability to incorporate various chemical substances and thus can be used for drug delivery purposes. Liposomes are composed of phospholipids, flexible in composition, and have shown great potential to improve delivery and targeting of bioactive substances which otherwise have poor bioavailability in the body. Conventional liposomes composed of various ...

Background and aims: The study aimed to identify yet unknown and uncharacterized long non-coding RNAs (lncRNAs) in treatment-naïve ulcerative colitis (UC), and to define their possible roles in UC pathogenesis. For that purpose, accurate quantification methods for lncRNA transcript detection, multiple and “stringent” strategies were applied. New insights in the regulation of functional genes and ...

Abstract Background Hip involvement predicts severe disease in juvenile idiopathic arthritis (JIA) and is accurately assessed by MRI. However, a child-specifc hip MRI scoring system has not been validated.<p> <p>Objective To test the intra- and interobserver agreement of several MRI markers for active and chronic hip changes in children and young adults with JIA and to examine the precision of ...

LTX-401 is a novel oncolytic compound designed for the local treatment of solid tumors. In the present study, we have examined the applicability and efficacy of LTX-401 in a rat model JM1 hepatocellular carcinoma, with particular interest in its ability to induce antitumor immunity. LTX-401 induces necrotic cell death followed by the release of immunogenic cell death mediators such as high-mobility ...

Ischemic injury worsens upon return of blood and innate immunity including the complement system play a central role in ischemia-reperfusion injury (IRI) as in thoracic aortic surgery. Complement component1 inhibitor (C1-INH) has been shown to reduce IRI and is a broad-acting plasma cascade inhibitor. We established a new porcine model of IRI by cross-clamping the thoracic aorta and evaluated the ...

DYRK1A is one of five members of the dual-specificity tyrosine (Y) phosphorylation-regulated kinase (DYRK) family. The DYRK1A gene is located in the Down syndrome critical region and regulates cellular processes related to proliferation and differentiation of neuronal progenitor cells during early development. This has focused research on its role in neuronal degenerative diseases, including ...

This thesis focuses on liver sinusoidal endothelial cells (LSEC) and one of their characteristic features called fenestrations. LSEC line the hepatic sinusoids and filter solutes from the plasma. The bidirectional transport of solutes between the bloodstream and the interior of the liver is facilitated via transcellular nanopores called fenestrations. Fenestrations are dynamic structures with diameters ...
