• Magnesium increased in the castor bean globoids but remained relatively constant in rice globoids.

• The extract was then dried with magnesium sulphate, filtered and evaporated on a rotary evaporator to 200 ml.

• In the absence of added ions the junctions were unstacked and extended, but underwent a folding transition upon addition of magnesium or other multivalent ions.

• Do women with pre-eclampsia, and their babies, benefit from magnesium sulphate?

• This demonstrates that magnesium-free medium and picrotoxin are abolishing directional selectivity by different mechanisms.

• The most frequent amino acid whose sidechain is contacting the magnesium ion is aspartate (42 %), followed by threonine (23 %), glutamate (17 %) and serine (10 %).

• Organic matter, carbon and nitrogen had the lowest coefficient of variation in leaf fall, while those for magnesium, phosphorus and potassium were intermediate.

• Iron-rich olivines have both reasonably fast reaction rates and contain ferrous iron in a solid-solution between the two olivine end-members fayalite (iron) and forsterite (magnesium).

• They speculated that magnesium inhibited the calcium calmodulin complexes thereby interfering with oocyte protein kinase activity.

• Spatial distribution of extractable phosphorus, potassium, and magnesium as influenced by fertilizer and tall fescue endophyte status.

• This makes it unlikely that the starburst amacrine cells are the source of the putative inhibition of the preferred-direction response in magnesium-free medium.

• However, in magnesium-free medium the response to preferred-direction motion is decreased.

• He received morphine, sodium bicarbonate, and calcium and magnesium supplements and was transfused with 20% human albumin solution, red blood cells and platelets.

• Thus brines expelled at a later time might have been both magnesium-rich and saline.

• It is suggested that these results might be attributed to a high concentration of magnesium ions.
