2. 1. Biotic and abiotic stress in microorganisms and plants: Some Mechanisms of Stress and Programmed Cell Death. Genetic Engineering Approaches Towards Improved Stress Tolerance

   Author : Per-Johan Meijer; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biotic stress; plants; microorganisms; stress tolerance; antifreeze protein; proline; programmed cell death; systemic aquired resistance; Biochemistry; metabolism; Biokemi; Bioteknik; Biotechnology; abiotic stress;

   Abstract : Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. READ MORE

4. 2. Light, stress and herbivory : from photoprotection to trophic interactions using Arabidopsis thaliana as a model organism

   Author : Martin Frenkel; Jon Moen; Stefan Jansson; Don Cipollini; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; photoprotection; herbivory; light-stress; jasmonate; fitness; FDE; dual-choice; Biology; Biologi;

   Abstract : Photosynthesis is the most important process for nearly all life on earth. Photosynthetic organisms capture and transfer light energy from the sun into chemical energy which in turn provides a resource base for heterotrophic organisms. Natural light regimes are irregular and vary over magnitudes. READ MORE

5. 3. Coordination of two different genomes in response to light and stress

   Author : Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

   Abstract : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. READ MORE

6. 4. Mental Stress and Endothelium-Dependent Vasodilation

   Author : Kristina Johansson; Sverker Jern; Uppsala universitet; []
   Keywords : Medical sciences; Mental stress; endothelium; adrenoceptor blockade; catecholamine; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Abstract : The endothelium plays an important part in blood flow regulation by producing the vasodilatory substance nitric oxide (NO). Various studies have shown that commonly accepted risk factors for coronary heart disease, such as hypertension, diabetes, hypercholesterolemia, smoking and mental stress impair endothelium-derived vasodilation by the NO-pathway.

7. 5. Women, work and stress

   Author : Annika Evolahti; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Work-related stress has become a major public health problem in Western societies. In Sweden women account for the majority of long-term sick leave and the most common reasons are psychiatric conditions such as depression and stress-related diagnoses. READ MORE
