BACKGROUND/AIMS: Cerebral ischemia often leads to breakdown of blood-brain barrier (BBB) and vasogenic edema. It remains to be established whether MEG3 is responsible for the hypoxic damage in neural cells. This study aimed to investigate the role of MEG3 in the hypoxia-induced injuries of PC12 cells. METHODS: The PC12 cells were seeded and cultured under hypoxia and normoxia culture conditions. The cell viability determined by trypan blue exclusion, apoptosis using propidium iodide (PI) and fluorescein isothiocynate (FITC)-conjugated Annexin V staining, cell-migration using a modified two-chamber migration assay with a pore size of 8 µM and invasion using 24-well Millicell Hanging Cell Culture inserts with 8 µM PET membranes...

The P2X7 is an adenosine triphosphate (ATP)-gated ion channel involved in several facets of immune activation and neuronal function through its importance in interleukin (IL)-1β secretion. We hypothesized that blockade of P2X7 would prevent perinatal brain injury associated with exposure to intrauterine (IU) inflammation. Dams received 45 mg/kg of Brilliant Blue G (BBG), a specific P2X7 receptor (P2X7R) antagonist, on gestation day 17 (E17) prior to administration of lipopolysaccharide (LPS) or phosphate-buffered saline (PBS)...

Maternal cigarette smoke exposure (CSE) during pregnancy is a well recognized causative factor for placental injury. Hydrogen sulfide (H2S), a gaseous signal molecule, has been shown to exert a protective effect against tissue injury in many organs. This study aimed to investigate whether H2S could alleviate CSE-induced placental injury in rats. Pregnant SD rats were randomly divided into 4 groups: NaCl, CSE, CSE + NaHS (a donor of H2S) and NaHS. On gestational day 21, placental weight was measured. Placental H2S content was assessed by methylene blue method...

Exposure to mercury (Hg) results in reproductive abnormalities and deficiencies in female fish. We traced the maternal assimilation and redistribution of dietary inorganic (HgII) and organic (MeHg) forms of Hg in a coastal marine fish, the Spot Leiostomus xanthurus. We conducted a 90-d laboratory experiment in which treatment Spot were fed muscle of Blue Marlin Makaira nigricans with elevated concentrations of Hg mixed with a commercial fish food, while control Spot were fed only commercial food pellets. Gonadal maturation was induced by shortening the photoperiod and increasing the temperature...

Intra-amniotic dye instillation is a useful tool for evaluation of equivocal cases of preterm prelabor rupture of membranes and for genetic amniocentesis in multifetal gestation. Indigo carmine, the most used and studied dye, is no longer available. We sought to provide a resource of potential dyes for clinical use that summarizes dosing along with maternal, fetal, and neonatal outcomes. We reviewed the literature evaluating the use of alternative agents. Sodium fluorescein has proven clinical usefulness but has side effects when used intravenously...

Maturation of cumulus-oocyte complexes (COCs) is crucial for further successful monospermic fertilization, embryo growth, and implantation. All these events are accompanied by proliferation and differentiation of cumulus cells. The migration of COCs to the oviduct after ovulation and the interaction between female gametes and/or embryos with maternal tissues are still poorly recognized on the molecular level. This study was aimed to first demonstrate the mRNA expression profile of cell migration markers during different stages of porcine oocytes maturation and developmental capability in vitro...

Vasculogenesis is a complex process by which endothelial stem and progenitor cells undergo de novo vessel formation. Quantitative assessment of vasculogenesis is a central readout of endothelial progenitor cell functionality. However, current assays lack kinetic measurements. To address this issue, new approaches were developed to quantitatively assess in vitro endothelial colony-forming cell (ECFC) network formation in real time. Eight parameters of network structure were quantified using novel Kinetic Analysis of Vasculogenesis (KAV) software...
