1. 1. Characterisation of Food Associated Bacteria by DNA based Methods, with Special Reference to Enterobacteriaceae

   Författare :Crister Olsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; 16S rRNA; TTGE; ribotyping; Rahnella; Klebsiella; HPI; Enterobacteriaceae; food; Livsmedelsteknik;

   Sammanfattning : The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. LÄS MER

3. 2. From behaviour to genes: anti-predator responses of brown trout (Salmo trutta) under winter conditions

   Författare :Karl Filipsson; Eva Bergman; Ann Erlandsson; Martin Österling; Johan Watz; Stefán Óli Steingrímsson; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; burbot; climate change; cortisol; diel behaviour; gene expression; HPI axis; light; mRNA; piscivorous; poikilotherm; predator; salmonid; stream; stress; temperature; thermal; winter behaviour; Biology; Biologi;

   Sammanfattning : Temperature has major effects on the performance of poikilotherms. In encounters with predators, low winter temperatures constrain predator detection and escape capabilities in prey fishes. LÄS MER

4. 3. Neuroendocrinology of agonostic interaction and social signalling in Artic charr (Salvelinus alpinus) : Studies on the neuroendocrine regulation of aggressive behaviour, stress responses and skin colour

   Författare :Erik Höglund; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Brain monoamines; social signalling; POMC; skin colour; stress; Salmonid; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; limnologi; Limnology;

   Sammanfattning : This thesis shows that socially subordinate Arctic charr (Salvelinus alpinus) display elevated brain serotonergic (5-HT) and norepinephric activity along with a chronic activation of the hypothalamic-pituitary-interrenal (HPI) axis, including elevated plasma concentrations of á-MSH. Furthermore, subordinate fish showed an inhibition of aggressive behaviour and darker body coloration, skin darkness being positively correlated with plasma á-MSH. LÄS MER

5. 4. Roles of Arginine-Vasotocin and Corticotropin-Releasing Hormone in Stress Responses and Agonistic Behaviour of Rainbow Trout

   Författare :Tobias Backström; Svante Winberg; Lynne Sneddon; Uppsala universitet; []
   Nyckelord :Zoophysiology; arginine-vasotocin AVT ; corticotropin releasing hormone CRH ; stress; stress coping; behaviour; rainbow trout; Zoofysiologi;

   Sammanfattning : The neuropeptides arginine-vasotocin (AVT) and corticotropin-releasing hormone (CRH) are involved in the hypothalamic-pituitary-interrenal (HPI) axis. During stress, the HPI axis is activated and cortisol is released into the blood. In addition to their role in the HPI axis, AVT and CRH also have behavioural effects. LÄS MER

7. 5. Alpha-radioimmunotherapy with At-211: Evaluations and imaging on normal tissues and tumors

   Författare :Tom Bäck; Göteborgs universitet; []
   Nyckelord :radioimmunotherapy; astatine; RBE; renal function; GFR; imaging; targeted radiotherapy; alpha-RIT;

   Sammanfattning : Alpha-radioimmunotherapy (alpha-RIT) is an internal conformal radiotherapy at the cellular level using alpha-particle emitting radionuclides. Alpha-particles have a very short range in tissues (... LÄS MER
