Apoptosis is a physiological, conserved program of cellular suicide, characterized by nuclear condensation, DNA-fragmentation and release of mitochondrial cytochrome c into the cytoplasm. The apoptotic program is executed by a cascade of highly specific caspases. The occurrence and significance of apoptosis in multinucleated, differentiated cells, like skeletal muscle cells is discussed controv...

Myosin is an essential driver of cardiac and skeletal muscle function. Multiple mutations identified in β-cardiac/skeletal slow myosin heavy chain (MYH7) fast 2A (MYH2), cause a group human diseases termed myosinopathies1. Over 90% these are found the filament-forming region coiled-coil tail, also known as light meromyosin (LMM). A mutation to proline residue or deletion single-residue common m...

Bone scan in diagnosis of infectious osteoarthritis  Bone scan with Technezium 99m is harmless methodoi evaluation of Skeletal lesions.It is safe 1n pedia­_ trics age group and it can be used in early diffe-rentiate osteomyelitis from cellulits sand also it may help in diagnosis of subsclinical  involvement of  eumatoid arthritis,benign and malignant bone  tumors stress fractures and periostit...

fasting induces short-term physiological adaptations which spare the body's remaining carbohydrate stores and mobilize lipid stores to provide a substitute fuel for many tissues and organs, especially skeletal muscle. rodent studies show that regular occurrence of fasting then refeeding, stimulates adaptations in muscle which make the animal better placed to withstand a further period of fastin...

retinoic acid (ra) plays a key role in pattern formation along the major body axis and limbformation during vertebrate development. exposure to excessive retinoic acid (in uterus) generatescongenital malformations in limbs, craniofacial, cns, urogenital, heart, and axial skeletons. in thesestudies, seven groups of nmri pregnant mice were administered a single gavage dose of 100 mg /kgbody weigh...

introduction: satellite cells are known as the main regenerative cell type in skeletal muscles. our study established a modified digestion and preplating method for the isolation of slow or weak adherent cells for the enrichment of satellite cells. low-survival rate of these primary stem cells prompted us to address whether cell culture medium substitution might change cell viability status. me...

background: the purpose of present study was to investigate whether sphingosine 1-phosphate (s1p) levels and its receptors gene expressions are correlated with myod and myogenin following resistance training. materials and methods: 24 eight-week-old male wistar rats (190-250 gr) were assigned randomly to a control (n = 12) or training (n = 12) group. rats climbed a resistance training ladder wi...

A healthy and independent life requires skeletal muscles to maintain optimal function throughout the lifespan, which is in turn dependent on efficient activation of processes that regulate muscle development, homeostasis, and metabolism. Thus, identifying mechanisms that modulate these processes is of crucial priority. Noncoding RNAs (ncRNAs), including microRNAs (miRNAs) and long noncoding RNA...

Testosterone exerts significant effect on muscle cells, and abnormalities of plasma concentra‐ tions can cause both skeletal muscle and cardiovascular diseases. Low levels are known to be associated with hypogonadism and have recently been linked to sarcopenia and metabol‐ ic syndrome; high levels are associated with hypertrophy. However, most evidence of the link between testosterone and metab...

Diseases affecting skeletal muscle exhibit considerable heterogeneity in intensity, etiology, phenotypic manifestation and gene expression. Systems biology approaches using network theory, allows for a holistic understanding of functional similarities amongst diseases. Here we propose a co-expression based, network theoretic approach to extract functional similarities from 20 heterogeneous dise...
