Abstract
INTRODUCTION The studies about effect of fetal anemia on placental and maternal molecular changes have rarely been published. This study aimed to compare oxidative stress levels and mitochondrial function in the placenta and maternal peripheral blood mononuclear cell (PMBCs) between anemic fetuses (using fetal Hb Bart's disease as a study model) and non-anemic fetuses. METHODS A cross-sectional study was conducted on pregnancies affected by Hb Bart's disease and non-anemic fetuses between 16 and 22 weeks of gestation. Placental tissue and maternal blood for PBMCs were collected after pregnancy termination for determination of oxidative stress and mitochondrial function. RESULTS A total of 18 pregnancies affected by Hb Bart's disease and 12 non-anemic fetuses were enrolled. Placental thickness was significantly greater (p-value <0.001) in the affected pregnancies, whereas all Doppler indices of uteroplacental blood flow were comparable. Mitochondrial dysfunction was significantly increased (p-value <0.001) in the placenta of the affected fetuses. In the mothers of affected fetuses, there was an increase in mitochondrial oxidative stress levels with a significant increase in mitochondrial dysfunction in isolated PBMCs (p-value <0.001). DISCUSSION In the presence of normal uteroplacental Doppler studies, fetal anemia can induce a significant increase in oxidative stress and mitochondrial dysfunction in the placentas and mothers. The findings support that the placenta can be a source of oxidative stress agents which are released into systemic circulation prior to development of maternal adverse outcomes, and may explain pathophysiology of subsequent preeclampsia in late gestation, as commonly seen in pregnancies affected by fetal Hb Bart's disease, if pregnancy is not terminated.

Abstract
The antibiotic diaminodiphenyl sulfone (DDS) is used in combination with other antibiotics as a first line treatment for leprosy. DDS has been previously reported to extend lifespan in Caenorhabditis elegans through inhibition of pyruvate kinase and decreased mitochondrial function. Here we report an alternative mechanism of action by which DDS promotes longevity in C. elegans by reducing folate production by the microbiome. This results in altered methionine cycle metabolite levels mimicking the effects of metformin and lifespan extension that is dependent on the starvation- and hypoxia-induced flavin containing monoxygenase, FMO-2.

Abstract
AIM The oxidative stress of placenta during fetal heart dysfunction (FHD) is lack of evaluation. So, we carried out an experiment to explore whether vitamin C (VitC) can be supplied for placental protection under FHD and its impacts on P-glycoprotein expression. METHODS Fetal heart dysfunction was induced by two intra-amniotic injections of isoproterenol, then (VitC) was supplied. Hematoxylin-eosin (HE) staining was used to evaluate placental histology, and oxidative stress was measured by total antioxidant capacity, total superoxide dismutase and level of advanced oxidation protein products (AOPP), as well as apoptosis rate. Real-time polymerase chain reaction was adopted to measure the expressions of superoxide dismutase-1 (Sod-1), glutathione peroxidase-1 (Gpx-1) and endothelial nitric oxide synthase (eNOS) in placenta. Finally, western blot was performed to detect P-glycoprotein expression. RESULTS All isoproterenol twice-treated fetuses exhibited significant (P < 0.05) contractile dysfunction by fetal echocardiography compared to others. The HE staining showed severe placental hydrops in the FHD group, and that hydrops could be reduced by VitC treatment. Total antioxidant capacity and total Sod-1 decreased in FHD and elevated after VitC supplementation. Also, level of AOPP increased in FHD and dropped after VitC supplementation. Analysis of apoptosis demonstrated that there was a mild increase in apoptosis rate of FHD. Reductions of Sod-1 and eNOS mRNA expression were confirmed in FHD, but these could recovered after VitC supplementation, with the same tendency of the P-glycoprotein. CONCLUSION Severe oxidative injuries were identified in placentas of FHD with P-glycoprotein repression. VitC administration can reduce the oxidative stress and rebuild the protective mechanism of placenta.

Abstract
Oxidative stress has been associated with a wide range of diseases including atherosclerosis, cancer and Alzheimer's disease. When present in excessive concentrations, reactive oxygen species (ROS) can cause deleterious effects. This has led to the notion that the anticancer effects of various chemotherapeutics may be mediated, at least in part, by an increase in ROS. To investigate the role of xanthine oxidase (XO), a source of hydrogen peroxide, in cell death, MCF7, HeLa and 293T cells were treated with various cell-death-inducing drugs in the presence and absence of allopurinol, a specific inhibitor of XO. In the absence of allopurinol, each drug led to a time- and concentration-dependent increase in percent DNA fragmentation and ROS levels, regardless of the mechanism of cell death incurred, i.e. caspase dependent and caspase independent. By contrast, pretreatment with allopurinol led to dramatically lower ROS levels in all cases, suggesting that XO is a major contributor to oxidative stress. However, allopurinol did not exhibit a protective effect against cell death. Similarly, the administration of siRNA against XO also did not exhibit a protective effect against cell death. The level of oxidative stress was recorded using the ROS sensor CM-H(2) DCFDA and a ratiometric bioluminescent assay that takes advantage of the increased sensitivity of Firefly luciferase to hydrogen peroxide, compared with a stable variant of Renilla luciferase (RLuc), RLuc8. Overall, these findings suggest that XO-generated hydrogen peroxide, and perhaps hydrogen peroxide in general, is a consequence, but not a mediator of cell death.
