1. The role of insulin signaling during development, reproductive diapause and aging in Drosophila Melanogaster
Sammanfattning : The insulin/insulin-like growth factor signaling pathway exists from invertebrates to vertebrates and it can regulate various biological processes, including development, metabolism, stress resistance and lifespan. In Drosophila, eight insulin-like peptides (DILP1-8) have been found. LÄS MER
2. Old-age muscle atrophy : cellular mechanisms and behavioral consequenses
Sammanfattning : With advancing age, humans and rodents alike lose about one third of the skeletal muscle mass. A process referred to as old-age muscle atrophy or sarcopenia. LÄS MER
3. Spinal motoneurones and the bulbospinal serotonininergic system in aged rats with behavioral deficits
Sammanfattning : The expression of neuropeptides, growth-related proteins and neurotrophin receptors were studied in motoneurons of young adult rats and in aged rats with symptoms of neuromuscular incapacities. Also studied were aging-related changes in the descending serotoninergic (5HT) bulbospinal system which constitutes a major afferent pathway to spinal motoneurons. LÄS MER
4. Changes in sensory systems during aging : an experimental study in the rat
Sammanfattning : Aging is associated with sensorimotor disturbances, including increased proprioceptive thresholds. The present study aimed to clarify the occurrence of structural and biochemical alterations in sensory systems of behaviorally characterized aged rats. LÄS MER
5. On age related changes in axons and glia of the central nervous system
Sammanfattning : A growing body of evidence shows that phenotypic changes including axon aberrations, rather than loss of neurons, account for behavioral impairments during aging. The present thesis was undertaken to investigate the occurrence of axon aberrations in relation to transmitter identity, glial reaction and sensorimotor disturbances. LÄS MER
