The role of environmental factors in regulating planktivorous predation : Interactive effects of turbulence and visibility conditions

Laura Härkönen

Visibility conditions of lakes in the Northern Hemisphere have been predicted to decline, due to climate change- induced variations in vegetation of the surrounding catchment areas, precipitation, soil erosion, as well as sediment resuspension. At the same time, climate models predict increasing wind and storm activities, resulting in increasing turbulent velocities in lakes. The aim her...

On Non-Scattering Energies

Esa V. Vesalainen

In this thesis, we extend the theory of non-scattering energies on two fronts. First, we shall consider the discreteness of non-scattering energies corresponding to non-compactly supported potentials using the approach via transmission eigenvalues and fourth-order operators. The method requires the support of the potential to exhibit certain compact Sobolev embedding and to be contained ...

VEGFR3 and Notch signaling in angiogenesis

Georgia Zarkada

Blood and lymphatic vessels form extensive networks throughout the body, which function in order to deliver oxygen and nutrients to the tissues, to remove extravasated fluid and to absorb dietary lipids. The formation of new blood and lymphatic vessels (termed angiogenesis and lymphangiogenesis) is critical during embryonic development and in the adult, and is regulated by multiple signa...

Enhanced Antibacterial Action of Bacteriocin Producing Cells by Binding to the Target Pathogen

Shanna Liu

Bacteriocins are natural weapons of bacterial inter-species competition in food preservation arsenal. Bacteriocins produced by lactic acid bacteria have gained particular attention owing to their potential application as the substitute of artificial chemical preservatives. This research made use of genetic engineering technologies to clone the class IIa bacteriocin genes and construct ba...

Kutsuminen, siunaaminen ja lähettäminen : Ordinaatiokaavojen käsitys pappisvihkimyksestä ja -virasta Suomen evankelis-luterilaisessa kirkossa 1963 - 2003

Juhana Pohjola

The purpose of this study is to determine the understanding of ordination and the pastoral office in the ordination rites of the Evangelical Lutheran Church of Finland (ELCF) from 1963 to 2003. The method is systematic analysis of the Agendas of the ELCF: T 1963, T 1984 and T 2003, which detail the ordination rites during that period. The rites were placed in their historical and ecumeni...

A clinical and health economical observational study of anti-tumor necrosis factor therapy in the treatment of rheumatoid arthritis in Finland

Liisa Virkki

Biological antirheumatic drugs are biotechnologically produced antibodies or fusion proteins that are used if rheumatic inflammation is not sufficiently ameliorated with conventional antirheumatic drugs. Approximately 10% of Finnish rheumatoid arthritis (RA) patients use biological drugs. Biological antirheumatic drugs target inflammatory mediators and cells. Tumor necrosis factor inh...

Transcription Factors Foxi3 and Sox2 in the Regulation of Tooth Development

Maria Jussila

Teeth are ectodermal organs, which form from the embryonic epithelium and mesenchyme. Reciprocal interactions between these two tissues, regulated by the conserved signaling pathways, guide tooth morphogenesis. Activity of each signaling pathway is mediated by transcription factors, which activate or repress target genes of the pathway. During morphogenesis, the shape of the dental epith...

Functional Sequence Annotation in an Error-prone Environment

Patrik Koskinen

As more and more sequences are submitted to public databases, so will grow more computationally challenging sequence retrieval systems. When for example the UniProtKB/TrEMBL doubles in size annually, the tools used today might not be sufficient tomorrow. Faster and computationally lighter methods are needed for sequence retrieval. This study presents a computationally more efficient tool...

Copper and bacteria related to Finnish Emmental cheese

Lourdes Mato Rodriguez

Traditional Swiss Emmental utilizes copper vats, whereas Finnish Emmental is manufactured using stainless steel cheese vats, and a copper sulfate solution is added into the cheese-milk to reach copper levels in the final cheese of a maximum 15 ppm. Other manufacturers use stainless steel vats but no copper is added. Despite the economical importance of Emmental cheese for the Finnish dai...

Ischaemia-Reperfusion-Induced Kidney Injury - Experimental studies on the effects of caloric restriction, AMPK activator AICAR and α2-adrenoceptor agonists in the rat

Juha Lempiäinen

Ischaemia-reperfusion (I/R) injury of the kidneys is a common cause of acute kidney injury (AKI). The incidence of AKI among hospitalized patients is between 2-10%, and the mortality rates are high. Currently there is no medication for AKI. The aim of the present study was to increase our knowledge of the pathophysiological mechanisms underlying ischaemic AKI and to identify tentative dr...
