hydatid cyst is an important endemic zoonosis in iran. it may be seen in various organs of body. musculoskeletal system is rarely involved by hydatid cyst, the larval form of echinococcus granulosus . on clinical basis, it may resemble any soft tissue tu-mor. a 70-years old housewife living in ardoghesh, a village in neyshabur, north-east iran, was admitted to general surgery clinic because of ...

Flexible metabolic phenotypes allow animals to adjust physiology to better fit ecological or environmental demands, thereby influencing fitness. Summit metabolic rate (Msum = maximal thermogenic capacity) is one such flexible trait. Skeletal muscle and heart masses and myocyte metabolic intensity are potential drivers of Msum flexibility in birds. We examined correlations of skeletal muscle and...

Complete software support has been developed for a direct memory access microprocessor system used to store and analyze diffraction data from striated muscle. These studies are based on the premise that the regularly alternating light and dark regions of the fiber behave like a phase grating to incident laser light. A knowledge of the position of a diffracted order can thus be used to determine...

Morphological, contractile, and histochemical properties of rat soleus muscle were studied after 2 or 4 weeks of complete elimination of neuromuscular activity. Inactivity was induced by chronic perfusion of tetrodotoxin (TTX) to the sciatic nerve. Significant reductions in muscle mass and fiber size were found after 2 or 4 weeks of disuse. Correspondingly, the percentage of dark-staining alkal...

introduction: at least 60% of the estimated 300,000 metric tons of tuna that are processed in iran areby-products which arebeingwasted and converted to non-human products as fish meal or fertilizers. therefore, a major challenge facing the tuna canning industry is to find the new processes to utilize tuna processing by-products (mainly dark muscle) into valuable foods. the characteristics of tu...

A new species of Microsporidia classified to a new genus was observed in the trunk muscle of commercial hake (Merluccius capensis/paradoxus complex) from Namibian fisheries. Macroscopic examination revealed thin and dark filaments inserted among muscle fibers. Inside the filaments were many sporophorous vesicles with about 30-50 spores per vesicle. The shape of the spore was pyriform and the ex...

SR~TER, F. A. Cell water, sodium, and potassium in stimulated red and white mammalian muscles. Am. J. Physiol. 205(6) : I 2951298. I g63.pPotassium and sodium concentration and inulin space were measured in samples of rat soleus, plantaris, and gastrocnemius muscles after indirect stimulation in situ for 4 min, 30 min, and 6 hr. Two samples were taken from the gastrocnemius muscle : one from it...

Cocaine and amphetamine regulated transcript (CART) encodes a novel brain-enriched protein whose features are reminiscent of a neurotransmitter propeptide. We have now localized CART peptide(s) in the gastrointestinal tract by immunohistochemical methods. Polyclonal antisera raised to CART peptide 106-129 stained neuronal cell bodies and fibers in rat ileum myenteric plexus-longitudinal muscle ...

A method utilizing a general dehydrogenase reaction has been used to demonstrate early gross myocardial infarctions. The procedure takes advantage of substrate and enzyme loss from the damaged myocardium. In the viable muscle, where endogenous substrates, coenzymes, and dehydrogenases are present, reduction of Nitro-BT yields a dark blue formazan. Necrotic muscle fibres remain unstained by this...
