BACKGROUND Effective fetal growth requires adequate maternal nutrition coupled to active transport of nutrients across the placenta, which, in turn requires ATP. Epidemiological and experimental evidence has shown that impaired maternal nutrition in utero results in an adverse postnatal phenotype for the offspring. Placental mitochondrial function might link maternal food intake to fetal growth...

Arsenic exposure mainly through food and water has been shown to be associated with increased incidence of numerous cancers and non-cancer harmful health. It is also used in cancer chemotherapy and treatment of several cancer types due to its apoptogenic effects in the various cancer and normal cell lines. We have already reported that liver is the storage site and important target organ in As ...

Mitochondria are vitally important organelles within our cells. In addition to being the key energy provider, they perform numerous other essential roles ranging from calcium homeostasis iron metabolism. Therefore, these mitochondrial functions dependent on quality and number of mitochondria, which needs be dynamic in response a cell’s changing needs. Mitochondrial numbers themselves controlled...

As the global climate continues to warm and greenhouse effect intensifies, plants are facing various abiotic stresses during their growth development. In response changes in natural environment, plant mitochondria regulate functions through morphological dynamic changes. Mitochondria highly organelles with ability continuously cleavage fuse, regulating homeostatic processes needs of organism ex...

In a sheep model, we investigated diet effects on skeletal muscle mitochondria to look for fetal programming. During pregnancy, ewes were fed normally (N) or were 50% food restricted (L) during the last trimester, and lambs born to these ewes received a normal (N) or a high-fat diet (H) for the first 6 mo of life. We examined mitochondrial function in permeabilized muscle fibers from the lambs ...

Neurotoxicity is the major health effect from exposure to lead for infants and young children, and there is current concern regarding possible toxic effects of lead on the child while in utero. There is no placental-fetal barrier to lead transport. Maternal and fetal blood lead levels are nearly identical, so lead passes through the placenta unencumbered. Lead has been measured in the fetal bra...
