Selected maternal, fetal and placental trace element and heavy metal and maternal vitamin levels in preterm deliveries with or without preterm premature rupture of membranes.

Aim: To compare maternal, fetal and placental trace element (magnesium, zinc and copper) and heavy metal (cadmium and lead) and maternal vitamin (retinol, α [alpha]-tocopherol, vitamin D , 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D ) levels in preterm deliveries with and without preterm premature rupture of membranes (PPROM).

Methods: Sixty-eight patients giving birth preterm were grouped into preterm deliveries with PPROM (n = 35) and without PPROM (n = 33). Following delivery, maternal and umbilical cord blood sera and placental tissue samples were obtained.

Determination of micronutrients and oxidative stress status in the blood of STZ-induced experimental diabetic rat models.

This study aims to research the effect of streptozotocin (STZ) at different doses on the serum micronutrients and oxidative stress status in diabetic rat models. Twenty male rats averaged 250 g and 3-4 months old were used as experimental models. They were put in four groups composed of five rats each.

Trace elements, heavy metals and vitamin levels in patients with coronary artery disease.

Aim: In the present study, we aimed to assess serum concentrations of zinc (Zn), copper (Cu), iron (Fe), cadmium (Cd), lead (Pb), manganese (Mn), vitamins A (retinol), D (cholecalciferol) and E (α-tocopherol) in patients with coronary artery disease (CAD) and to compare with healthy controls.

Methods: A total of 30 CAD patients and 20 healthy subjects were included in this study. Atomic absorption spectrophotometry (UNICAM-929) was used to measure heavy metal and trace element concentrations.

Serum selenium, vitamin E, and sialic acids concentrations in lambs with white muscle disease.

The aim of this study was to determine the serum concentrations of selenium, vitamin E, and total- and lipid-bound sialic acid (LBSA) in lambs with white muscle disease (WMD) before and after treatment with a commercial preparation containing selenite and vitamin E. Fifteen lambs with WMD and ten control animals were used as research materials. Blood samples were collected from both groups before- and 1 month after treatment for Se analysis by fluorimetry, whereas vitamin E and sialic acid were measured by HPLC and spectrophotometry, respectively.
