“…Taken together, our results are consistent and it should be kept in mind that an inter-individual variability could be explained to some extent by the fact that element concentrations may vary during pregnancy [29,32] and the gestational age is not the same for all the patients from this cohort.…”

Background-The impact of nanoparticles we are increasingly exposed to remains largely unknown. Of particular concern is the exposure of pregnant women and potential impact on fetal development. Indeed, many in vitro and in vivo animal studies have shown that nanoparticles are able to cross the placental barrier and induce toxic effects to the fetus. However, little is known in humans. Objective-The aim and originality of this study were to investigate the nanoparticle burden of amniotic fluids in pregnant women. Methods-To that purpose, 100 amniotic fluids collected for clinical purposes were used to determine the nanoparticle quantity and nature by inductively coupled plasma atomic emission spectroscopy (NAMIOTIC, ClinicalTrials.gov Identifier: NCT02720887). Results-The prevalence of patients with a substantial concentration for the essential trace elements Cu, Fe and Zn was high, while that of patients with a substantial concentration of Al, Ag, Be, Co, Cr, Ni, Si, Ti and W was relatively low (under 20%). It was generally higher in the fraction containing nanoparticles and ions than in the fraction containing micro-and submicroparticles. No correlation was found between the nanoparticle burden and the different potential sources of exposure to nanoparticles (smoking status of the patient, living area, heating source, mode of transport, leisure, use of hygiene products and cosmetics and occupational activities). Conclusion-Our results showing low concentrations and low prevalence of most of the assessed elements in amniotic fluids are reassuring. Further research is needed to draw firm conclusions on the developmental toxicity of engineered nanoparticles in humans but the present paper can provide a useful basis for further evaluation of the fetal toxicity of nanoparticles.

“…The composition of amniotic fluid (AF) is important for fetal development and reflects both maternal and fetal compartments. The content of elements in the AF can provide important information on the nutritional and mineral status of the mother and her fetus as well as their exposure to toxic elements [ 1 – 3 ]. During pregnancy, physiologic and metabolic changes in the woman’s organs depend on the requirements of the growing fetus.…”

The objective of this study was to determine the concentration and the reference ranges of essential and toxic elements in amniotic fluid (AF) and maternal serum (MS) at birth. This study was conducted among 175 healthy pregnant Caucasian European women aged 18-42. AF and maternal blood samples were collected during delivery. An inductively coupled plasma mass spectrometry (ICP-MS) technique was used to determine the levels of Mg, Co, Cu, Zn, Sr, Cd, Ba, Pb, U, Ca, Cr, Al, Mn, V, Fe, As, Se and Sb in AF and MS. The range of reference values was calculated for all analyzed elements in the serum and AF. The mean concentrations of elements, except Pb, were generally higher in MS than in AF. Multiple regression analysis showed that the maternal/newborn body mass (MBM/NBM) ratio was a strong negative predictor (among maternal age and gravidity) of Mg concentration in amniotic fluid. In the serum, MBN/NBM ratio was a strong positive predictor of Cu concentration. Moreover, regression analysis showed that maternal age was an independent positive predictor of the Se level in maternal serum. The reference value ranges of 18 essential and toxic elements were established in AF and MS among a population of healthy pregnant Polish women at delivery. The level of Mg, Co, Cu, Ca and Se in AF and MS can be determined by maternal age and MBM/NBM ratio. These results can be useful in counseling individuals with pregnancies affected by exposure to one of the parameters under investigation.

“…There was a significant difference ( p < .05) in the zinc content of the Amankwatia and AGRA rice flours. Manganese is also involved in the metabolism of macronutrients including fats, carbohydrate and proteins (Lewicka et al, ). The amount of manganese recorded for the Amankwatia and AGRA rice varieties were 2.26 and 1.16 mg/100 g, respectively.…”

The proximate and mineral contents of two Ghanaian rice varieties (Amankwatia and AGRA) were assessed by standard methods. Results showed significant difference as for proteins solubilized by media with various dissociating abilities and revealed the presence of several disulfide‐rich proteins. The two varieties showed similar contents as for ash, protein, crude fiber, and carbohydrate, whereas significant difference (p < .05) in the fat content was observed. Protein overall structure was addressed by solubility and SDS‐PAGE electrophoresis, while water binding capacity, swelling power, and bulk density accounted for the functional properties. No significant difference (p > .05) existed in the bulk density, except for swelling power and water binding capacity of the rice varieties. Potassium was the predominant mineral in both rice flours and significant differences existed among the contents of manganese, zinc, iron, magnesium, sodium, and potassium. Thus, the rice varieties have very useful constituents for developing new rice‐based food products. Practical applications The study showed the presence of hydrophobic interactions and disulfide bonds stabilizing proteins in the Amankwatia and AGRA rice flours. Structural features of the protein network in the two aromatic rice flours developed in Ghana was also revealed through SDS‐PAGE electrophoresis. This is essential towards understanding the chemistry of the rice flours and to appreciate their subsequent utilization in food product development. The higher water absorption capacity of AGRA rice flour makes it useful as thickener in food formulations. The excellent nutrient profile of Amankwatia and AGRA rice flours, compared with others implies these two rice varieties, can compete with other imported rice varieties which are generally perceived to be of higher quality in Ghana. The need to encourage the consumption of these two locally produced rice varieties is justified.
