Immune Responses to Pathogen Infection in Arabidopsis

Mantas Survila

To survive, plants must recognize the presence of danger and establish effective defenses against invading pathogens. Most plants are resistant to the majority of plant pathogens. This passive protection is provided primarily by the cell wall and waxy cuticular layer that limit the progress of most attackers.

Presence of hepatitis E virus (HEV) and markers for HEV infection in production swine, human patients with unexplained hepatitis, and veterinarians in Finland

Tuija Kantala

Hepatitis E virus (HEV) infections are common in both humans and animals. HEV genotypes 1 and 2 (HEV-1 and HEV-2) only infect humans and are endemic to Asia, Africa, and Central America, where they cause large, usually waterborne hepatitis epidemics. HEV-3 and HEV-4 are zoonotic and in addition to humans, they also infect animals. Especially HEV-3 is common in swine globally. The porcine...

Geochemical impacts on the release of silicon within entire watersheds

Virpi Siipola

This thesis focused on the bioreactive pools of silicon (Si) in sediments and phenomena affecting Si release from sediments. There are several potentially mobile pools of Si in sediment, e.g. biogenic Si (BSi), dissolved Si, and adsorbed Si (AdSi). These various Si pools make the investigation of a single pool challenging because of the interference caused by other Si pools. To evaluate ...

Metabolic and inflammatory factors in upper extremity soft-tissue disorders

Martti Rechardt

Upper extremity soft tissue disorders (UESTDs) are common painful conditions relating to tendons and their adjacent structures. The etiology of UESTDs, particularly the role of metabolic and inflammatory factors, is unknown. Some studies have found associations between obesity and diabetes with UESTDs. To date, few studies have assessed the role of cytokines in UESTDs and virtually nothi...

Spectra of linear fractional composition operators and properties of universal operators

Riikka Schroderus

The topics of this thesis in mathematics belong to the area of operator theory which, in general, studies linear transformations between complete normed vector spaces. Here, all operators considered are bounded and act on complex separable infinite-dimensional Hilbert space. A prototypical example of Hilbert spaces is formed by the square summable sequences of complex numbers. Other comm...

Bird populations in a changing world: implications for North European conservation

Sara Fraixedas

Primary sclerosing cholangitis (PSC) is particularly common in the Nordic countries. Most (70-80%) PSC patients have concomitant inflammatory bowel disease (IBD). The majority of patients are male.

WATERBIRDS IN A CHANGING WORLD: EFFECTS OF CLIMATE, HABITAT AND CONSERVATION POLICY ON EUROPEAN WATERBIRDS

Diego Pavón Jordán

Climate change has become a major threat for biodiversity in recent decades. Waterbirds, in particular, are very responsive to climate change compared to other avian species and have already shown changes in phenology and distribution. Such strong and rapid response of some species to climate change has motivated debate about the effectiveness of the site-safeguard network, as climate ch...
