PAK signalling in neuronal physiology

Cellular Signalling, 2009
Group I p21-activated kinases are a family of key effectors of Rac1 and Cdc42 and they regulate many aspects of cellular function, such as cytoskeleton dynamics, cell movement and cell migration, cell proliferation and differentiation, and gene expression. The three genes PAK1/2/3 are expressed in brain and recent evidence indicates their crucial roles

Wnt Signaling: Physiology and Pathology

Growth Factors, 2004
Signaling by the Wnt family of secreted glycoproteins has been demonstrated to be essential both in normal embryonic development and in the pathogenesis of a variety of diseases, including cancer. This signaling pathway is exquisitely regulated by a large and complex array of proteins, which act as agonists or antagonists of signal transduction ...

Thrombopoietin Signalling in Physiology and Disease

Growth Factors, 2004
Thrombopoietin (TPO) is a key physiological regulator of steady-state megakaryocytopoiesis, the process of megakaryocyte production and maturation that ultimately results in the formation of platelets. Ten years have passed since the purification and cloning of TPO and extensive studies of the activities of recombinant forms of the cytokine, as well as

Physiology and Mathematics of Myoelectric Signals

IEEE Transactions on Biomedical Engineering, 1979
The myoelectric (ME) signal is the electrical manifestation of the neuromuscular activation associated with a contracting muscle. It is an exceedingly complicated signal which is affected by the anatomical and physiological properties of muscles, the control scheme of the peripheral nervous system, as well as the characteristics of the instrumentation ...

CSF signaling in physiology and behavior

2000
Publisher Summary Cerebrospinal fluid (CSF) has traditionally been considered as a drainage system for the brain. Recent work provides compelling evidence that the CSF provides a route of communication for signals. There are several aspects of existing evidence for CSF signaling that are particularly impressive.

Physiological Foundations of Neural Signals

2013
One of the central goals in neuroscience is to understand the function of neural circuits in the brain and how they are related to behavior. As a result, a great effort has been dedicated to developing techniques which enable the recording of the brain’s electrical activity at different spatial scales.

AKT Signaling in Physiology and Disease

2010
The serine/threonine kinase AKT functions as a critical mediator of signaling downstream of PI3 kinase. Studies over the last two decades have firmly established the importance of AKT in the regulation of cell survival, proliferation, and insulin-dependent metabolic cell responses.

Active Sensors for the Acquisition of Physiological Signals

2018 IEEE SENSORS, 2018
The acquisition of physiological signals from human subjects has been an important research area for quite some time. Common issues involved in standard schemes for acquisition and processing of physiological signals, such as the possibility of the electrodes being easily damaged, or the probability of irritation upon prolonged usage, necessitate the ...
