1. 6. Fish community patterns in Tanzanian mangrove creeks

   Författare :Augustine Mwandya; Martin Gullström; Olof Lindén; Stockholms universitet; []
   Nyckelord :Mangrove ecosystems; fish assemblages; Mugil cephalus; population genetics; spatial and seasonal variability; human disturbance; East Africa; NATURAL SCIENCES; NATURVETENSKAP; Animal Ecology; zooekologi;

   Sammanfattning : Human beings have exploited the biota of mangrove systems for centuries and fish continue to be one of the main products harvested from these habitats. The assumption of mangroves functioning as recruitment areas for juvenile fish from neighbouring habitats such as seagrass beds and coral reefs is a common argument for conservation and management of mangrove ecosystems.

3. 7. Effects of Antioxidant and Lipid Lowering Treatment on Risk Factors for Cardiovascular Disease : With special reference to Mixed Tocopherols and Stable Fish Oil

   Författare :Meilin Liu; Afaf Kamal-Eldin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cardiovascular disease; Antioxidants; Tocopherols; Endothelial constitutive nitric oxide synthase; Superoxide dismutase; Protein kinase C; Fish oils; Fatty acids; Simvastatin; Lipoprotein; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; rättsmedicin; Forensic Medicine;

   Sammanfattning : Vitamin E in food, polyunsaturated fatty acids (PUFAs) and lipid lowering treatment with statins have been found to decrease the risk for cardiovascular disease (CVD) and cardiac death. However, clinical trials revealed no beneficial effect of intake of alpha-tocopherol alone. LÄS MER

4. 8. Habitat compensation in nature-like fishways : Effects on benthos and fish

   Författare :Stina Gustafsson; Olle Calles; Martin Österling; Jostein Skurdal; Paul Giller; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biocanal; biodiversity; brown trout; freshwater pearl mussel; functional feeding groups; habitat heterogeneity; large woody debris; macroinvertebrates; PIT-tag; salmonids; Biology; Biologi;

   Sammanfattning : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. LÄS MER

5. 9. Improved Nutritional Support in Cancer Patients

   Författare :Christina Persson; Ursula Falkmer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Cancer; weight loss; PG-SGA; dietary advice; education; fish oil; melatonin; Onkologi; Oncology; Onkologi; Oncology; onkologi;

   Sammanfattning : Weight loss and other nutritional problems are common in cancer patients. The problems are of importance for response to treatment and survival and the well-being of the patients.Nutritional support can be carried out in different ways. LÄS MER

7. 10. Molecular studies of pancreatic cancer: Characterization of the transforming growth factor beta signaling pathway

   Författare :Tord Jonson; Avdelningen för klinisk genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SMAD4; PCR; FISH; cytogenetics; chromosome; pancreatic cancer; TGFB signaling; cytogenetik; Genetik; Genetics;

   Sammanfattning : In the present thesis, genetic abnormalities in pancreatic cancer were studied, with special emphasis on alterations of components involved in the transforming growth factor beta (TGFB) signaling pathway. In the first study, fluorescence in situ hybridization and cytogenetic analyses revealed aberrations of chromosome 18 in all 13 pancreatic carcinoma cell lines studied, in particular frequent breaks close to the centromere of chromosome arm 18q.
