6. Bacterial Adaptive Responses - Coping with Oxygen Limitation, Reactive Nitrogen Species and Disulfide Stress
Sammanfattning : Bacteria have a remarkable ability to adapt to different environments. When bacteria encounter stress that causes macromolecular damage in the cell, leading to a suboptimal performance of cell metabolism, they can elicit an adaptive response. LÄS MER
7. Coping with environmental stress : from the individual and population perspective
Sammanfattning : Natural stress and disturbances are important factors affecting the structure and function of ecosystems. However the magnitude of stress has escalated due to anthropogenic activities. Environmental monitoring and toxicity assessments try to protect ecosystems from unwanted human alterations. LÄS MER
8. Light, stress and herbivory : from photoprotection to trophic interactions using Arabidopsis thaliana as a model organism
Sammanfattning : 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. LÄS MER
9. Influence of Oxidative Stress on Muscle and Bone
Sammanfattning : Reactive oxygen species (ROS) induce oxidative stress and although are primarily recognized for playing a deleterious biological role, they can be beneficial to cell systems. ROS are extremely short-lived and normally tightly regulated by antioxidant defence systems. LÄS MER
10. Aspects of Regulation of GFR and Tubular Function in the Diabetic Kidney : Roles of Adenosine, Nitric Oxide and Oxidative Stress
Sammanfattning : Diabetic nephropathy is the main cause for initiation of renal replacement therapy and early symptoms in patients include increased glomerular filtration rate (GFR), decreased oxygen tension and albuminuria, followed by a progressive decline in GFR and loss of kidney function. Experimental models of diabetes display increased GFR, decreased tissue oxygenation and nitric oxide bioavailability. LÄS MER
