Ribosome distribution in skeletal-muscle myofibres was investigated by immunohistochemistry and microdensitometry by using anti-(60 S ribosomal subunit) antibodies. Administration of the 8J-adrenoceptor agonist clenbuterol caused an increase in the staining of the myofibrillar region with this antibody relative to that found in the subsarcolemmal cytoplasm. A similar effect was observed during ...

BACKGROUND A body of evidence demonstrating changes to the glutaminergic system in tendinopathy has recently emerged. This hypothesis was further tested by studying the effects of glutamate on the tenocyte phenotype, and the impact of loading and exposure to glucocorticoids on the glutamate signaling machinery. METHODS Plantaris tendon tissue and cultured plantaris tendon derived cells were i...

BACKGROUND Plantaris tendon, peronus brevis tendon and flexor hallucis longus tendon augmentation, commonly used in Achilles tendon rupture, often lead to weakening of injured foot and they require the immobilization after the surgery. It is essential to develop the technique, which gives no such limitation and allows for immediate functional improvement. METHODS We present our method of mini...

The human plantaris muscle (PM) is a small, spindleshaped muscle that originates from the femur just above the lateral condyle and the adjacent posterior ligament of the articular capsule, in close association with the lateral head of the gastrocnemius. Its proximal region varies from a thin fibrous structure to a muscle belly, equal in size to the lateral head of the gastrocnemius. Ordinarily ...

Many techniques have been described for the treatment of an acute achilles tendon rupture, but there is unfortunately no agreement between orthopedic surgeons regarding the best repair technique and post-treatment rehabilitation protocol. Overall, the surgical methods can be classified as either an open procedure or as a percutaneous procedure. While numerous techniques have been described for ...

Anatomic and operative textbooks and current literature do not clearly describe the Achilles tendon interface to the calcaneal tuberosity. We dissected 51 specimens to identify the detailed anatomy of the Achilles tendon insertion. Achilles tendon fascicles expanded from the anterior aspect of the distal Achilles tendon over the retrocalcaneal bursa to the anterior part of the Haglund's tuberos...
