Contraction and cation contents of skeletal soleus and EDL muscles in age-matched control and diabetic rats
… proteins of Extensor Digitorum Longus (EDL) and soleus skeletal muscles compared to age-matched control rats. Adult Wistar rats were humanely killed and EDL and soleus muscles were located and excised rapidly and placed in organ baths. The muscles were electrically stimulated (EFS, 50 V, I msec, …

Metabolic profile of myosin heavy chain-based fiber types in the rat soleus after spinal cord transection
… at multiple time points (1, 3 and 6 months) in soleus fibers of rats following spinal cord transection (ST). To accomplish this, female Sprague-Dawley rats (~150 g, n = 15) were subjected to complete transection of the spinal cord at a mid-thoracic level. Age and weight-matched, non-operated …

The Role of Membrane Lipid Composition on Sarco(endo)plasmic Reticulum Calcium ATPase Function in Rat Soleus Muscle
Sarco(endo)plasmic reticulum calcium ATPase (SERCA) is a transmembrane protein whose function is regulated by its immediate lipid environment (annulus). The composition of the annulus is currently unknown or it’s susceptibility to a high saturated fat diet (HSFD). Furthermore it is uncertain if …

The temporal relationship between cardiolipin biosynthesis and remodeling enzymes and cardiolipin content during unloading atrophy in mouse soleus
… increased in tenotomy-induced atrophied mouse soleus, suggesting the upregulation of Taz may play a role in slowing this process. Thus, the purpose of this thesis was to examine the temporal relationship between enzymes of CL biosynthesis and remodelling and CL content during unload induced …

Change in the Number of Fibers and Nuclei in the Rat Soleus Muscle During Normal Development and Increased Work Load Exercise
… development. Increased work load exercise of the soleus muscle was induced by cutting the tendon of the synergestic gastrocnemius. Histological sections of the soleus were used in the studies.</p> <p>Changes of a 67% increase in muscle cell nuclei, a 74% increase in connective tissue cell nuclei …

The Effect of Leucine Supplementation on Biomarkers of Mitochondrial Biogenesis and Protein Synthesis in Soleus Muscle of Rats Fed a High-Fat Diet
… for 42 days. At the conclusion of 42 days, the soleus was extracted and used for analysis. Quantitative PCR was conducted to determine gene expression for PGC-1α, TFAM, mtIF2, TUFM, and COX-IV. RESULTS: mtIF2 gene expression increased 4-fold (p < 0.05) and TFAM gene expression increased 5-fold, …

Membrane properties and calcium ion activity in skeletal muscle fibres of the dystrophic mouse
… resistance) reached adult magnitude in normal soleus and extensor digitorum longus (EDL) by 4 weeks and 3 weeks respectively. Electrophysiological parameters in dystrophic soleus developed in a similar maimer to normal muscle, but RMP in dystrophic EDL was reduced and input resistance was …

The Role of Slow-Twitch Skeletal Muscle in the Musculoskeletal Endocrine Axis
… digitorum longus (EDL) muscles and slow twitch soleus muscles were then isolated for ex vivo contractility testing and tibia was obtained for analysis of trabecular bone content. In muscle, L-BAIBA supplementation showed no effect on muscle mass or EDL contractile function but increased …

The effect of dietary creatine supplementation on compensatory muscle hypertrophy and performance characteristics of specific fiber types
… and the plantaris ablated, to hypertrophy the soleus. One of each of these groups had their diet supplemented with creatine monohydrate. The size of the EDL and soleus were measured following surgical removal of the synergistic muscle and a 5-week supplementation period. Peak force, total …

The effectiveness of manipulation combined with static stretching of the gastrocnemius-soleus complex compared to manipulation alone in the treatment of subacute and chronic grades I and II ankle inversion sprains
A dissertation presented in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Technikon Natal, Durban, South Africa, 2001.

H-reflex changes with loading and unloading
Soleus H-reflex has been tested clinically in lying position. Stresses on the spine vary during lying, standing, weight lifting and unloading. This may influence the H-reflex. The purpose of this study was to measure the changes that might occur in the soleus H-reflex during such loading and …

Skeletal Muscle Function, Morphology, and Biochemistry in Ts65Dn Mice: A Model of Down Syndrome
… this did not lead to oxidative stress. Ts65Dn soleus muscles displayed normal force generation in the unfatigued state, but exhibited muscle weakness following fatiguing contractions. We show that a reduction in cytochrome c oxidase expression may contribute to the impaired muscle performance …

Changes in Skeletal Muscle Sarcoplasmic Reticulum Function in Adult and Aged Fisher 344 Brown x Norway Rats
… as a result of aging in the following muscles: soleus, plantaris, and diaphragm. The soleus is composed of slow twitch muscle fibers. The plantaris is composed of fast twitch muscle fibers, and the diaphragm is composed of both slow and fast twitch muscle fibers. Fisher 344 Brown x Norway Cross …

The effects of a high fat diet on musculoskeletal health in aged male C57BL/6J mice
… contractile measures were performed on isolated soleus and extensor digitorum longus (EDL) muscles at baseline (BSL, 20 weeks of age, n=11) and at the end of the 13-week intervention when AGE (n=12) and HFS-AGE (n=12) mice were 33 weeks of age. Both the AGE and HFS-AGE groups had similar declines …

The regulation of ceramide content and insulin resistance in skeletal muscle
… under the various conditions in the isolated rat soleus muscle. A submaximal insulin stimulus (100 ,aU/ml) increased 3-O-methylglucose transport by -2.7 fold over basal conditions in the soleus (1.90 ± 0.23 µmol•ml"1•hr-1 vs. 5.06 ± 0.38 µmol•ml-1•hr-1, respectively) (P < 0.05). Five hours of …

Immunolocalization of dystrophin and neurofilament protein in muscle spindles of normal, mdx-dystrophic, and denervated mice
… and in the mdx mouse. Muscle spindles in the soleus of 32-week-old normal and age-matched mdx mice were examined by immunocytochemical methods to determine the localization of dystrophin in polar and equatorial regions of the intrafusal fibers. Spindles were serially-sectioned in transverse …

Can low-dose lithium supplementation protect against sarcopenic obesity in ovariectomized mice?
… not alter body composition. Force production of soleus and EDL were significantly lower in OVX-con mice compared to sham-con. Li supplementation increased force production of soleus and EDL in OVX mice. Muscle fatigability was improved in soleus, but not EDL, of sham and OVX mice provided with Li …
