Electrophoretic study on the taxonomic relationship of the two morphologically very similar sea urchins echinostrephus aciculatus and echinostrephus molaris

, : Electrophoretic study on the taxonomic relationship of the two morphologically very similar sea urchins echinostrephus aciculatus and echinostrephus molaris. Comparative Biochemistry & Physiology B 88(2): 637-642

1. The taxonomic relationship of two morphologically very similar sea-urchins, Echinostrephus aciculatus. A. Agassiz and E. molaris (Blainville), was examined by means of gel electrophoresis of 18 different enzyme systems. 2. The results demonstrated that the two species shared common allozymes at 25 of the 26 genetic loci studied here and that the Nei's genetic identity value (I = 0.963) obtained between the two species was comparable to those already reported between conspecific local populations of many other animals. 3. Their genetic similarity verified by the present electrophoretic study and their morphological and ecological similarity strongly suggest that E. aciculatus and E. molaris may belong to one and the same species.

The aim of this present study is to test the effects of a novel linear polyethylenimine-NONO nitric oxide donor (DS1) applied topically on vaginal blood flow and hemodynamic parameters in rats. A laser Doppler was used to measure blood flow change...

Purpose: to compare the results obtained in healthy preterm vs full-term newborns, at 3 and 8 months of age, by p-VEPs and f-VEPs recordings. Methods: we examined 20 healthy preterm newborns (28-35 weeks of gestational age (GA)), recording f-VEPs,...

An isolated ventricular septal defect (VSD) was diagnosed in 70 patients (39 men and 31 women, mean age 29 years, range 10-64 years). Surgery was judged unnecessary. The follow-up period was at least 10 years, or until death or 31 December 1988, c...

The profile of 137Cs, due to Chernobyl accident, in undisturbed soil was measured experimentally over the years 1987 to 1994 and was found to remain practically fixed in the upper 30 cm of soil since 1987. Total deposition of 137Cs at the site was...
