Effect of a prebiotic supplement on knee joint function, gut microbiota, and inflammation in adults with co-morbid obesity and knee osteoarthritis: study protocol for a randomized controlled trial

Autor: Rafael Fortuna, David A. Hart, Keith A. Sharkey, Rachel A. Schachar, Kelly Johnston, Raylene A. Reimer

Publikováno v: Trials, Vol 22, Iss 1, Pp 1-10 (2021)

Abstract Background Osteoarthritis (OA) is a chronic and painful condition where the articular cartilage surfaces progressively degenerate, resulting in loss of function and progressive disability. Obesity is a primary risk factor for the development

Effects of β-hydroxy-β-methylbutyrate supplementation on muscle mass and strength in onabotulinumtoxin type-A-injected and contralateral quadriceps femoris in rabbits

Autor: Rafael Fortuna, Andrew Sawatsky, John C. Fuller, Jr., Walter Herzog

Publikováno v: Journal of Rehabilitation Medicine, Vol 53, Iss 9, p jrm00229 (2021)

Objective: To determine the effects of the leucine metabolite β-hydroxy-β-methylbutyrate (HMB) on strength, muscle mass, and contractile material in muscle wasting induced by onabotulinumtoxin type-A (BoNT-A) injection into the quadriceps femoris m

Force depression following a stretch-shortening cycle is independent of stretch peak force and work performed during shortening

Autor: Rafael Fortuna, Hannah Kirchhuebel, Wolfgang Seiberl, Geoffrey A. Power, Walter Herzog

Publikováno v: Scientific Reports, Vol 8, Iss 1, Pp 1-8 (2018)

Abstract The steady-state isometric force following active muscle shortening or lengthening is smaller (force depression; FD) or greater (residual force enhancement; RFE) than a purely isometric contraction at the corresponding length. The mechanisms

Force depression following a stretch‐shortening cycle depends on the amount of residual force enhancement established in the initial stretch phase

Autor: Rafael Fortuna, Tobias Goecking, Wolfgang Seiberl, Walter Herzog

Publikováno v: Physiological Reports, Vol 7, Iss 16, Pp n/a-n/a (2019)

Abstract Studies on residual force enhancement (rFE) and residual force depression (rFD) of the muscle‐tendon unit (MTU) have typically been conducted independent of each other, with little information available on how stretch‐induced rFE affects

Messenger RNA profiling of rabbit quadriceps femoris after repeat injections of botulinum toxin: Evidence for a dynamic pattern without further structural alterations

Autor: Rafael Fortuna, Walter Herzog, David A. Hart

Publikováno v: Muscle & Nerve. 57:487-493

Introduction: Onabotulinum toxin-A (BoNT-A) is widely used clinically, but might cause adverse effects. Earlier studies showed repeat BoNT-A injections did not cause progressive atrophy or function loss. The purpose of this study was to assess the in
