Ovine mitochondrial DNA sequence variation and its association with production and reproduction traits within an Afec-Assaf flock.
Polymorphisms in mitochondrial DNA (mtDNA) protein- and tRNA-coding genes were shown to be associated with various diseases in humans as well as with production and reproduction traits in livestock. Alignment of full length mitochondria sequences from the 5 known ovine haplogroups: HA (n = 3), HB (n = 5), HC (n = 3), HD (n = 2), and HE (n = 2; GenBank accession nos. HE577847-50 and 11 published...
متن کاملPolygenic variation and transmission factors involved in the resistance/susceptibility to scrapie in a Romanov flock.
Data from 4049 Romanov sheep belonging to a flock affected by natural scrapie were analysed by using survival-analysis techniques. Failure time was defined as the period of time between first exposure to infection and the date that animals left the flock with scrapie signs. Four hundred and forty-seven sheep were identified as 'scrapie animals'. Several models, including level of exposure as a ...
متن کاملOn the Geomagnetic Lunar Daily Variation Field
The geomagnetic lunax daily variation field, L, was studied using all available results of lunar analysis of geomagnetic data from a total of 37 stations. Equivalent external (overhead) and internal (induced within the earth) electric current systems responsible for L variations with respect to dip latitude were estimated by the method of spherical harmonic analysis for each season. The externa...
متن کاملAtmospheric Modulation of the Geomagnetic Daily Variation
Seasonal asymmetry in the daily variation of the geomagnetic declination has been studied for the observatories of Honolulu, Hawaii, Tucson, Ariz., and San Juan, Puerto Rico, for an 11-yr. period. Behavior unsymmetrical with respect to the seasonal change of solar radiation is conspicuous and suggests the action of an atmospheric factor, probably the large-scale air circulation in the lower ion...
متن کاملDaily variation in the effects of furosemide in rats.
Daily variation in the effects of furosemide, a loop diuretic agent, was examined in Wistar rats maintained under conditions of light from 7 a.m. to 7 p.m. and dark from 7 p.m. to 7 a.m. Furosemide (30 mg/kg) was given orally at 12 p.m., 4 a.m., 8 a.m., 12 a.m., 4 p.m. or 8 p.m. Urine was collected for 8 hr after furosemide administration, and urinary excretions of sodium and furosemide were de...
