Usually mathematicians use Hodgkin-Huxley model or FitzHug-Nagumo model to simulate action potentials of skeletal muscle fibers. These models are electrically excitable, but skeletal muscle fibers are stimulated chemically. To investigate skeletal muscle fibers we use a model with six ordinary differential equations. This dynamical system is sensitive to initial value of some variables so it is...

Introduction: Rhabdomyosarcoma is a high-grade malignant neoplasm with skeletal muscle differentiation; common soft tissue sarcoma in children but considered one of the rarest adults. Case description: We report case 35-year-old male chronic productive cough and haemoptysis for five days. A CT scan nasopharynx revealed blocked left maxillary ethmoid sinus bone destruction. These findings raised...

Cervical cancer is the most common malignancy in Indian women. Cervical cancer usually spread by local extension and through the lymphatics to the retroperitoneal lymph nodes. Direct invasion of muscles by primary growth is more common than by metastatic involvement. We present a case of carcinoma of the cervix post radiotherapy to pelvis who on follow up presented with biceps muscle metastases...

Rhabdomyosarcoma, a malignancy showing features of skeletal muscle differentiation, is the most common soft tissue sarcoma of childhood. The identification of distinct clinical presentation patterns, histologic tumor types, and risk groups suggests that rhabdomyosarcoma is a collection of highly related sarcomas rather than a single entity. In an effort to understand this seemingly heterogeneou...

PURPOSE Skeletal muscle metastases (SMM) from non-small cell lung cancer (NSCLC) are rarely encountered in clinical practice. The prognosis and the adequate treatment are not known. The aim of the study was to report our experience and to make an extensive literature research concerning SMM. PATIENTS AND METHODS In our unit, we identified 16 patients with SMM in a 10-year period. The source o...

Chordomas are rare neoplasms that do not often metastasize. Of the small percent that do metastasize, they very infrequently involve skeletal muscle. Only a few cases of skeletal muscle metastases have been reported in the literature. We report an unusual case of a patient with a primary sacrococcygeal chordoma who experienced a long period of remission but who subsequently developed recurrence...

: Breast cancer is one of the most common malignancy in Chinese women. Up to 80% patients with metastatic breast develop bone metastasis resulting local destruction and skeletal-related events such as pathological fracture spinal cord compression. Skeletal-related pose an enormous impact on patients' motor function quality life. Therefore, prevention treatment objectives metastasis, which often...

Cervical cancer is the fourth most common cancer in women worldwide, with a large majority of prevalence (85%) in developing countries. As of 2012, it accounts for 7.5% of all female cancer deaths. Despite its high prevalence, skeletal muscle metastasis from cervical cancer is extremely uncommon. In our extensive literature search, we were able to find only 8 cases where skeletal muscle metasta...

muscle tissue, skeletal muscle as well as cardiac muscle, is commonly affected in mitochondrial disorders. one explanation for this observation is that muscle tissue has a high-energy demand and therefore is more sensitive to a deficiency of mitochondrial energy production than some other tissues. in mitochondrial disorders, skeletal muscle tissue may be affected primarily by defective respirat...
