OBJECTIVES The aims of this study were to detect the acetylcarnitine resonance line at 2.13 ppm in the human vastus lateralis and soleus muscles, assess T1 and T2 relaxation times, and investigate the diurnal and exercise-related changes in absolute concentration noninvasively, using proton magnetic resonance spectroscopy at 7 T. MATERIALS AND METHODS All measurements were performed on a 7 T ...

The role of methionine enkephalin (ME) neurons in the development of genetic hypertension in SHR is the subject of this study. Methionine enkephalin-like immunoreactivity (MELI) and ME receptor binding (MERB) levels were assayed quantitatively by microdensitometry of fluorescence micrographs and autoradiographs of 85 cerebral nuclei and areas of both young and adult spontaneously hypertensive r...

The aim of this study was to evaluate the effect of neuromuscular fatigue on vastus medialis and vastus lateralis co-contraction. Fifteen healthy young subjects performed an isometric leg extension test in two different condition phases: i) maximum test for determining the maximum voluntary isometric contraction, and ii) fatigue test for exercises executed at 50% of the maximum voluntary contra...

Sarcolipin (SLN) and phospholamban (PLN) inhibit the activity of sarco(endo)plasmic reticulum Ca(2+)-ATPases (SERCAs) by reducing their apparent affinity for Ca(2+). A ternary complex between SLN, PLN, and SERCAs results in super-inhibition of SERCA activity. Analysis of skeletal muscle homogenate has limited our current understanding of whether SLN and PLN regulate SERCA1a, SERCA2a, or both in...

The purpose of the present study was to evaluate the acute effects of an upper limb static-stretching (SS) protocol on the maximal concentric jump performance. We recruited 25 young healthy, male, resistance trained individuals (stretched group, n = 15 and control group, n = 10) in this study. The randomized between group experimental protocol consisted of a three trials of maximal concentric j...

ABSTRACT: The animal performance on pasture is directly correlated to canopy structure since this influences the herbage consumption. This study was evaluated effects of four pre-grazing heights (12, 20, 28 and 36 cm) Andropogon lateralis Ness intake feeding behavior steers in a natural grassland under intermittent stocking management, using same proportion defoliation (40% reduction height, i....

Aim: The aim of this study is to determine the average morphometric parameters scapula accurate and successful analyzes in clinic. Material Methods: A total 24 dry bone were included study. Parameters determined on scapula; superio-inferior glenoid diameter (SIGD), anterio-posterior 1 (APG1), 2 (APG2), 3 (APG3), width (SW), length (SL), basis-spina distance (BS), spina (SSW), acromiocoracoid (A...

INTRODUCTION Peripheral nerve vasculitis is an important condition which can be diagnostically challenging and is one of the principal current indications for nerve and muscle biopsy. Previous studies have suggested that combined nerve and muscle biopsy (usually of the superficial peroneal nerve and peroneus brevis muscle) produces a higher diagnostic yield than nerve biopsy alone in the invest...

OBJECTIVE To determine the effects of a weight-bearing rehabilitation program on quadriceps and gluteus medius electromyographic activity, pain, and function in subjects diagnosed with patellofemoral pain syndrome (PFPS). DESIGN Pretest and posttest 6-week intervention study. SETTING Musculoskeletal research laboratory. PARTICIPANTS Fourteen subjects diagnosed with PFPS and 14 healthy con...
