Oocyte maturation, fertilization, and embryo development in vitro by green and chemical iron oxide nanoparticles: a comparative study.

Oxidative stress is considered one of the main challenges for in vitro maturation (IVM) and makes assisted reproductive technology (ART), including IVF and embryonic development less effective. Reducing free radicals via biocompatible nanoparticles (NPs) is one of the most promising approaches for developing IVM. We investigated the comparative effect of green and chemically synthesized iron oxide nanoparticles (IONPs) with an aqueous extract of date palm pollen (DPP) on oocyte parameters related to the IVM process.

Effect of Moderate Static Magnetic Fields on Mice Oocyte Vitrification: Calcium-Related Genes Expression.

The ability to cryopreserve oocytes without ultrastructural injury has been a concern in the development and use of methods to preserve female reproduction. The stability of the cell membrane must be preserved to reduce the damage caused by ice crystals during vitrification. One approach that has been explored is the use of static magnetic fields (SMFs), which are believed to influence cell membrane stability.

FeO magnetic nanoparticles improve the vitrification of mouse immature oocytes and modulate the pluripotent genes expression in derived pronuclear-stage embryos.

The vitrification of Germinal Vesicle (immature) oocytes is beneficial for preservation of fertility in cases involving reproductive problems. The use of nanoparticles (NP(s)) as vitrification aid is a novel approach towards improving vitrification efficiency. The efficacy of use of iron oxide (FeO) nanoparticles as vitrification aid is reported in this paper.

Serum iron level, ferritin and total iron binding capacity level among nonpregnant women with and without melasma.

Background: Melasma is a common acquired disorder characterized by symmetric, hyperpigmented patches with an irregular outline, occurring most commonly on the face. It is most prevalent among young to middle-aged women. Although iron overload affects skin pigmentation, effect of iron deficiency on skin is not clear.
