1. Morphometrical Methodology in Quantification of Biological Tissue Components
Abstract : Objective:To develop and validate computer-assisted morphometrical methods, based on stereological theory, in order to facilitate the analysis and quantitative measurements of biological tissue components.Material and methods:Biopsy specimens from the vaginal wall or from the vestibulum vaginae of healthy women, or from women suffering from incontinence or vestibulitis were used.

2. Giant Cell Arteritis - Pathogenetic and Epidemiological Aspects
Abstract : Giant cell arteritis (GCA) is a chronic inflammatory disorder of medium-size and large arteries which affects people aged 50 years or older with a female preponderance. The two different expressions of GCA are temporal arteritis (TA) and polymyalgia rheumatica (PMR). READ MORE

3. Experimental Stroke and Neurotrophins: Regulation, function and gene transfer of neurotrophins in rat and mouse models of focal cerebral ischemia
Abstract : Stroke caused by focal cerebral ischemia is a major cause of death and neurological disability in humans. The forebrain region most commonly affected by ischemic incidents is that supplied by the middle cerebral artery. READ MORE

4. Neuroprotection and neurogenesis after experimental stroke
Abstract : In this thesis, two potential endogenous mechanisms for neuronal survival and repair have been investigated in a rat model of stroke, middle cerebral artery occlusion (MCAO): signaling of the GDNF family of neurotrophic factors, and neurogenesis from endogenous progenitor cells. As determined by in situ hybridization for GDNF family ligand and receptor genes, MCAO caused widespread upregulation of both components of the functional GDNF receptor, c-Ret and GFRalpha1, indicating that GDNF may be a survival signal in stroke.

5. Grain Morphology and Intergranular Structure of Si3N4 and Al2O3 Based Ceramics
Abstract : This thesis concerns factors controlling the grain morphology in Si3N4 and Al2O3 based ceramics. The microstructures of the ceramics were characterized by scanning electron microscopy in combination with quantitative microscopy and stereologic methods. READ MORE
