Book Description
Biological processes resulting in observable cell state changes, such as synaptic plasticity inneuronal dendritic spines and muscular hypertrophy in skeletal muscles, share common characteristics. Both are influenced by calcium signaling, metabolic networks, mitochondria, and protein kinase activation. This research presents computational models of these processes, offering insights into synaptic plasticity and the skeletal muscle response to exercise. The first model is a spatial representation of mitochondrial ATP generation during calcium signaling in neurons, emphasizing the role of mitochondrial ER contact sites in increasing calcium levels in the mitochondria, thus enhancing mitochondrial potential. This model underscores the importance of subcellular geometry, metabolic consumption rates, and transport processes in ATP production, in addition to enzymatic activity. The second model is a compartmental model exploring the role of signaling frequency in protein kinase activation in dendritic spines. This model analyzes the interaction between the canonical neuronal signaling cascade, the AMP-Activated Protein Kinase (AMPK) cascade, and the insulin signaling cascade in conditions of high neurotransmitter stimulation rates, which activate calcium signaling and consume significant cellular energy. The final model, a logic-based representation of skeletal muscle signaling in response to resistance, endurance, and sprint exercise, investigates potential mechanisms of exercise-induced changes in mitochondrial morphology. Together, these models deepen our understanding of the dynamic interplay between signaling and metabolism in synaptic plasticity and exercise physiology, laying the groundwork for further investigation and potential development of therapeutic strategies for neurological disorders and improvements in exercise efficiency.

Pages : 408
Book Description
Recognition that aging is not the accumulation of disease, but rather comprises fundamental biological processes that are amenable to experimental study, is the basis for the recent growth of experimental biogerontology. As increasingly sophisticated studies provide greater understanding of what occurs in the aging brain and how these changes occur

Skeletal Muscle Structure, Function, and Plasticity
Author: Richard L. Lieber
Publisher: LWW
ISBN:
Category : Health & Fitness
Languages : en
Pages : 328
Book Description
In its Third Edition, this text addresses basic and applied physiological properties of skeletal muscle in the context of the physiological effects from clinical treatment. Anyone interested in human movement analysis and the understanding of generation and control from the musculoskeletal and neuromuscular systems in implementing movement will find this a valuable resource. A highlight color has been added to this edition's updated figures and tables, and the color plates section has been doubled, ensuring that all figures that need color treatment to clarify concepts receive this treatment. A new Clinical Problem feature uses concepts presented in each chapter in the context of a specific clinical case--for example, a spinal cord injury, a sports accident, or rehabilitation after bed rest.
