We have produced three dimensional reconstructions, at a nominal resolution of 5 nm, of thick filaments from scorpion and Limulus skeletal muscle, both of which have a right-handed four-stranded helical arrangement of projecting subunits. In both reconstructions there was a distinct division of density within projecting subunits consistent with the presence of two myosin heads. Individual myosi...
42 Computer A Survey of Storage Options I f you were a personal computing enthusiast in 1984, you could buy an IBM PC for $5,000 to $6,000—about $8,000 to $9,500 in today's currency. For this you would get a 0.004-GHz 8-bit processor with 0.064 Mbytes of RAM, a 12-inch monochrome text-only display, a 0.16-Mbyte floppy drive, and no possibility of a hard drive. Compare that with a PC purchase to...
Recent advances in wireless electronic and communications provide us the ability to build small, economical sensors with low power consumption and many diverse applications. Limited energy capacity of sensors is a huge challenge that will affect these networks. Clustering has been used as a well-known method to handle this challenge. To find appropriate location of clusters' heads, imperialist ...
The effect of 5-azacytidine (5-azaCR) on head regeneration and budding in hydra are reported. Hydra attenuata were exposed to various doses of 5-azaCR for 48 h and then decapitated and cultured. Head regeneration and bud formation were observed for 12 days after decapitation. Untreated control hydra regenerated heads within 7 to 8 days of decapitation with a budding index of 0.2. Buds invariabl...
The aim of the present study was to compare three methods of estrus synchronization in ewes during the non-breeding season. Forty-two ewes were randomly grouped for three treatments with different intravaginal devices for 12 days: Group A) CIDR, Group B) Self-made P sponge, Group C) MAP (medroxyprogesterone acetate) cream sponge. Furthermore, all groups were divided into two treatments with (R)...
Spontaneous mutations from sterile to fertile were demonstrated in four different cytoplasmic male-sterile stocks of pearl millet. One stock, ASM-3, was of African origin, and the other three, LMS-1A, ASM-5, and ASM-7, all had the same cyptoplasm of Indian origin, but differed in nuclear make-up. These reversions were shown to be plasmon mutations, rather than genic in nature. ASM-3 mutated at ...
Nontraumatic anterior subluxation and dislocation of the hip joint are extremely rare. A 58-year-old woman presented to our outpatient clinic with left hip pain with a duration of 15 years. There was no history of trauma or other diseases. Her hip pain usually occurred only on walking and not at rest. Physical examinations demonstrated no tenderness in the hip joint. The range of motion of both...
