Parental origin of triploidy and D and G trisomy in spontaneous abortions. | A cytogenetic study of 15 triploid spontaneous abortuses, 12 trisomic abortuses, and their parents was carried out using the Q-banding technique. Polymorphic regions in abortus chromosomes were compared to corresponding regions of parental chromosomes to determine the origin of the extra chromosomes. Using marker chrom... | 490,581 | [

Effect of orthophosphate on the rate of calcium uptake by red and white muscle sarcoplasmic reticulum. | In the presence of added orthophosphate (Pi) there is a period during which sarcoplasmic reticulum vesicles (SR) accumulate calcium at a constant rate. This constant rate is increased and is reached sooner when the added Pi concentration is increased. A double reciprocal plot of rate and Pi concentration gives a straig... | 490,625 | [

[Effect of infiltrating water vapors on mercury-zinc elements in implanted electric cardiac stimulators]. | A complex character of the water vapours effect on the energy source used in electrical pacemaker is investigated on the RMCC-1 type Hg-Zn element. The water vapours were shown to cause electrolyte effluence and hence the appearance of the leakage eddy currents amounted up to 22mA through the insulation of electrodes. ... | 491,897 | [
