Acesta excavata (Fabricius, 1779) is a slow growing bivalve from the Limidae family and often found associated with cold-water coral reefs along European continental margin. Here we present compositional variability of frequently used proxy elemental ratios (Mg/Ca, Sr/Ca, Na/Ca) measured by laser-ablation mass spectrometry (LA-ICP-MS) compare it to in-situ recorded instrumental seawater paramet...

in order to determine calcium (ca), magnesium (mg) content and total antioxidant capacity (tac) of seminal plasma in buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls; semen quality was evaluated, seminal plasma was then harvested by centrifugation and its ca and mg content were estimated and its tac determined. the ca ...

To investigate uterine and serum Ca++ and Mg++ variations during the estrous cycle in the bovine, 66 genital tracts and blood samples were collected from Urmia abattoir, Urmia, Iran. The phase of the estrous cycle was determined by examination of the structures present on ovaries and uterine tonicity. Of the collected samples, 17 were pro-estrus, 12 estrus, 14 metestrus and 23 diestrus. The ute...
