1. Deg/HtrA proteases of the cyanobacterium Synechocystis sp. PCC 6803 : from biochemical characterization to their physiological functions
Sammanfattning : The family of Deg/HtrA proteases is present in a wide range of organisms from bacteria, archaea to eukaryota. These ATP-independent serine endopeptidases play key roles in the cellular protein quality control. The cyanobacterium Synechocystis sp. LÄS MER
2. Physiological roles of amyloid precursor protein in vivo - zebrafish as a model
Sammanfattning : Amyloid-beta precursor protein (APP) is an evolutionarily conserved transmembrane protein expressed in many different tissues. APP belongs to a gene family consisting of two other APP-like proteins (APLP1 and APLP2). LÄS MER
3. Impact of food quality on aquatic consumers : Behavioral and physiological adjustments
Sammanfattning : Food quantity and quality together determine growth rates of consumers and the utilisation efficiencies of available resources in aquatic and terrestrial ecosystems. The effect of food quality on the performance of consumers is dependent on both, its direct influence on ingestion and assimilation rates, and on the behavioural and physiological adjustments of consumers to their food environment.

4. Biosynthesis and physiological functions of N-acyl amino acids
Sammanfattning : N-acyl amino acids are lipid signalling molecules that have recently been identified in biological systems. These lipids are structurally related to the endocannabinoids, although they do not activate cannabinoid receptors. LÄS MER
5. Luminal Hypotonicity and Duodenal Functions : An Experimental Study in the Rat
Sammanfattning : After drinking water, the fluid quickly leaves the stomach thereby creating a hypotonic luminal environment in the duodenum. This in turn constitutes a potential threat to the integrity of the duodenal epithelium. It therefore seems highly likely that luminal hypotonicity activates physiological mechanisms that aim to increase luminal osmolality. LÄS MER
