Mineral characteristics and the in vitro hemolytic activity of three synthetic and two natural calcium silicates (CaSi) are compared. Hemolysis is higher for the synthetic compounds than for the natural ones. The difference is accentuated by weak ultrasonication of the minerals. No variation was observed within the two groups, including both acicular and fibrous forms. Calcium was released from...

Calcium oxalate and silica minerals are common components of a variety of plant leaves. These minerals are found at different locations within the leaf, and there is little conclusive evidence about the functions they perform. Here tools are used from the fields of biology, optics, and imaging to investigate the distributions of calcium oxalate, silica minerals, and chloroplasts in okra leaves,...

OBJECTIVE Objectives of this study were 1) to investigate the mineral intake by Chinese lactating women, 2) to explore the dietary source of minerals, and 3) the ratios between different dietary minerals. METHODS A total of 468 lactating women in 5-240 days post-partum participated in this study. Food intakes by participants were measured using one time of 24-hour dietary recall, and minerals...

The prebiotic significance of laboratory experiments that study the interactions between oligomeric RNA and mineral species is difficult to know. Natural exemplars of specific minerals can differ widely depending on their provenance. While laboratory-generated samples of synthetic minerals can have controlled compositions, they are often viewed as "unnatural". Here, we show how trends in the in...

background: minerals are essential materials in animal reproduction. the determination of these elements is valuable in relation to different conditions in arabian horses. objectives: the purpose of this study was to evaluate the effects of pregnancy on certain macro and micro minerals in arabian horses. methods: blood samples were collected from one hundred apparently healthy mares from differ...

The serum of calcium, other involved minerals and parathyroid hormone (PTH) were studied in non-pregnant women, during pregnancy and in pregnancy-induced hypertension (PIH). In pregnant women, serum creatinine, total calcium, total protein, albumin, inorganic phosphorus and magnesium declined, while parathyroid hormone levels increased significantly when compared to non-pregnant women. In PIH c...

Twenty-one minerals are considered to be nutritionally essential, or probably essential, to the animal. Depending on the quantities required by the animal, they can be grouped into major minerals and trace (minor) elements. Of the major minerals the most important are calcium, phosphorus, sodium, chlorine, potassium, sulphur and magnesium. The important trace elements are copper, cobalt, iron, ...
