Controversy exists as to whether mammalian skeletal muscle is capable of volume regulation in response to changes in extracellular osmolarity despite evidence that muscle fibres have the required ion transport mechanisms to transport solute and water in situ. We addressed this issue by studying the ability of skeletal muscle to regulate volume during(More)
In this paper, we present a highly integrated 60 GHz CMOS/PCB single-chip digital phased array solution, embedded in QFN package. This represents a unique opportunity to develop low power 60GHz multi-gigabit radio at a similar cost structure as a Bleutooth® radio, addressing the needs of a multitude of bandwidth hungry wireless multimedia(More)
Affective touch sensation is conducted by a sub-class of C-fibres in hairy skin known as C-Tactile (CT) afferents. CT afferents respond maximally to gentle skin stroking at velocities between 1 and 10 cm/s. Parkinson's disease (PD) is characterised by markedly reduced cutaneous C-fibres. It is not known if affective touch perception is influenced by C-fibre(More)
Mouse and rat skeletal muscles are capable of a regulatory volume increase (RVI) after they shrink (volume loss resultant from exposure to solutions of increased osmolarity) and that this RVI occurs mainly by a Na-K-Cl-Cotransporter (NKCC)-dependent mechanism. With high-intensity exercise, increased extracellular osmolarity is accompanied by large increases(More)
The purpose of this thesis was to investigate the role of lactate in the regulatory volume response of mammalian skeletal muscle to hypertonic challenge-induced cell shrinkage. It was demonstrated that adult mice skeletal muscle single fibres responded to increased extracellular osmolarity in a dose-dependent manner when exposed to NaCl or sucrose(More)
