The Release of Phosphate from the Electric Organ of Torpedo
The electroplates of the electric organ of Torpedo are embryonically derived from striated muscle fibres which lose their ability to contract and develop greatly expanded end-plate surfaces (cf. Rosenberg, 1928). From consideration of the thermodynamics of the Torpedo organ discharge, Bernstein (1912) concluded that the electric energy of the discharge was derived from a difference between the ...
متن کاملEvolution and comparative genomics of subcellular specializations: EST sequencing of Torpedo electric organ.
Uncharacterized open reading frames (ORFs) in human genomic sequence often show a high degree of evolutionary conservation, yet have little or no tissue EST or protein data suggestive of protein product function. The encoded proteins may have highly restricted expression in specialized cells, subcellular specializations, and/or narrow windows during development. One such highly specialized and ...
متن کاملThe Fine Structure of the Electric Organ of Torpedo Marmorata
The fine structure of the electric organ of the fish Torpedo marmorata has been examined after osmium tetroxide or potassium permanganate fixation, acetone dehydration, and Araldite embedment. This organ consists of stacks of electroplaques which possess a dorsal noninnervated and a ventral richly innervated surface. Both surfaces are covered with a thin basement membrane. A tubular membranous ...
متن کاملAssociation of the HNK-1 epitope with 5'-nucleotidase from Torpedo marmorata (electric ray) electric organ.
5'-Nucleotidase isolated from the electric organ of the electric ray (Torpedo marmorata) has a molecular mass of 62 kDa and, on two-dimensional electrophoresis, separates into up to 13 isoforms within a pI range of 5.9-6.7. The N-terminal sequence data show a 71% identity over 17 amino acids with that previously published for the rat liver enzyme. All forms of 5'-nucleotidase are recognized by ...
متن کاملthe effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
