Rapid oscillations in cytosolic calcium (Ca2+) coordinate muscle contraction, relaxation, and physical movement. Intriguingly, dietary nitrate decreases ATP cost of contraction, increases force production, and increases cytosolic Ca2+, which would se

Patient Perspectives on Transitions from Acute to Community-Based Physiotherapy Care Following Total Knee Replacement Surgery Within the Context of a Bundled Care Model

Autor: Emily Chen, Stuart Brownell, Taylor DiBrita, Aden Green, Lindsay McPherson, Rehginald Ragos, Caroline Jones, Alison Bonnyman, Gonxhe Kastrati, Karen Yoshida, Amanda Smart

Publikováno v: Physiotherapy Canada.

Purpose: Research on fiscal implications of the bundled care (BC) model exist; however, patient-perceived experiences are less well known. As BC expands in Ontario, this study aims to examine these experiences with physiotherapy care within the total

Assessment of Na+/K+ ATPase Activity in Small Rodent and Human Skeletal Muscle Samples

Autor: Sebastian Jannas-Vela, Stuart Brownell, George J. F. Heigenhauser, Heather L. Petrick, Lawrence L. Spriet, Graham P. Holloway

Publikováno v: Medicine & Science in Sports & Exercise. 51:2403-2409

In skeletal muscle, the Na/K ATPase (NKA) plays essential roles in processes linked to muscle contraction, fatigue, and energy metabolism; however, very little information exists regarding the regulation of NKA activity. The scarcity of information r

Compensatory increases in protein markers of mitochondrial dynamics during ageing are adaptable to physical activity

Autor: Paula M, Miotto, Pierre-Andre, Barbeau, Stuart, Brownell

Ageing is associated with an upregulation of mitochondrial dynamics proteins mitofusin 2 (Mfn2) and mitochondrial dynamics protein 49 (MiD49) in human skeletal muscle with the increased abundance of Mfn2 being exclusive to type II muscle fibres. Thes

Compensatory increases in protein markers of mitochondrial dynamics during ageing are adaptable to physical activity

Autor: Stuart Brownell, Pierre-Andre Barbeau, Paula M. Miotto

Publikováno v: The Journal of Physiology. 595:5753-5754

In most tissues of the human body, mitochondria play a key role in providing energy to support cellular and mechanical processes. In this regard, electrons are transferred through complexes I-IV of the electron transport chain (ETC), and the free ene
