The aim of this study was to investigate the longitudinal changes in serum paraoxonase-1 (PON1) activity from preconception throughout normal pregnancy and their relationships with maternal dietary vitamin C and E intake. The study was performed in 35 women (studied at preconception, at 8, 20 and 32 weeks of pregnancy, and at labour). PON1 activity decreased significantly from 145.8 (109.8-198.8) U/L at preconception to 111.1 (85.3-179.9) U/L (p<0.01) at 32 weeks and 100.4 (54.7-171.4) U/L (p<0.001) at labour. There was a direct association between vitamin C intake and PON1 at week 32 (p=0.018). We conclude that adequate vitamin C intake in pregnant women may merit consideration, since vitamin C supplementation has proved beneficial in the prevention of preeclampsia in women at increased risk of this condition.

Peroxisomes01:24

Peroxisomes

Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...
Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
