Future research may expose that gourd ornaments and 'bombillas' made of this mineral complex are the cause of the cancers.
Osteoid consists mostly of a fibrous protein called collagen, while the mineral complexes are made up of crystals of calcium and phosphate, known as hydroxyapatite, that are embedded in the osteoid.
Mineral complexes were formed in the presence of BSF, HSA, or both in DMEM inoculated with 3 mM calcium and phosphate as before; they were then washed and subjected to SDS-PAGE (Fig. 8A C; see also Materials and Methods).
On the other hand, the marked reduction of the number of bands associated with NB seen under serum-free conditions, observed here as well as in earlier studies [12], [19], can be explained by a dilution effect, with the initial serum proteins bound to NB becoming diluted by new mineral complexes being formed, eventually ending with just the more abundant proteins remaining visible.
In a healthy state, these nascent mineral complexes are likely to get removed from the serum by binding to calcification inhibitors like fetuin-A and albumin, followed by phagocytosis by the reticuloendothelial system (RES), or perhaps via excretion in the urine [30], [40], [83].
We cannot establish whether these organo-mineral complexes were present in the soil and have been extracted or whether they are formed between two dissolved separated phases.
The resulting phytate-mineral complexes are generally insoluble at physiological pH, which obstructs mineral uptake in the human intestine and leads to mineral deficiencies, such as iron deficiency anaemia [14,15].
However, even under these conditions, the protein-mineral complexes were not completely dissolved as judged by the presence of small precipitates seen with subsequent centrifugation and by the retention of high molecular weight complexes visible in the space between the spacer and separating gels when the treated NLP samples subjected to SDS-PAGE analysis.
The Bushveld Complex is a mineral-rich area that is being extensively mined.
There was a noticeable decrease in band intensity as compared with Figure 8B, indicating that albumin incorporation into the mineral complex had been significantly reduced.
