although the biokinetics, metabolism, and chemical toxicity of atorvastatin calcium are well known, until recently little attention was paid to the potential toxic effects of atorvastatin calcium on re-production and development in mammals. in recent years, it has been shown that atorvastatin calcium is a developmental toxicant when given orally or subcutaneously (sc) to mice. decreased fertili...

In view of the importance of fatty acids as substrates for the mature heart, fatty acid oxidation by fetal and calf heart mitochondria has been investigated. Free fatty acids of 10 carbon units or less which exhibit carnitine-independent transport into mitochondria were effective substrates for oxidative phosphorylation in both fetal and calf heart mitochondria. Efficient oxidative phosphorylat...

A combined morphological and biochemical investigation of mitochondria from developing and rapidly growing tissues ( tumors, fetal, and very early neonatal rat liver) revealed mitochondria which were deficient in respiratory control, showed no valinomycin induced K(+) accumulation or spontaneous Ca(++) uptake, and were unable to undergo a swelling-contraction cycle. Electron microscopic examina...

In order to study the aging changes of intramitochondrial RNA synthesis of mouse adrenocortical cells, 10 groups of developing and aging mice, each consisting of 3 individuals, total 30, from fetal day 19 to postnatal newborn at day 1, 3, 9, 14, adult at month 1, 2, 6 and senescent animals at month 12 (year 1) and 24 (year 2) were injected with 3H-uridine, an RNA precursor, sacrificed 1 hr late...

For the purpose of clarifying the aging changes of DNA synthesis of mouse mitochondria in adrenal medullary cells, 10 groups of aging mice, each consisting of 3 individuals, total 30, from fetal day 19 to postnatal newborn at day 1, 3, 9, 14, adult at month 1, 2, 6, 12 and 24, were injected with 3 H-thymidine, sacrificed 1 hr later and the adrenal tissues were fixed and processed for electron m...

In order to study the aging changes of intramitochondrial macromolecular synthesis in various organs of aging animals during the development and aging, 10 groups of developing and aging mice, each consisting of 3 individuals, total 30, from fetal day 19 to postnatal newborn at day 1, 3, 9, 14 and adult at month 1, 2, 6, 12 to 24 were injected with H-thymidine a DNA precurson, another 10 groups ...

Human retinal pigment epithelium (RPE) contains two genetically distinct forms of superoxide dismutase (SOD) enzymes that scavenge harmful superoxide anions. Biochemical and immunochemical techniques were used to compare levels of copper-zinc- and manganese-containing forms of SOD (CuZn-SOD and Mn-SOD) in human adult and fetal RPE cells. It was found that Mn-SOD activity was higher in adult tha...

The ultrastructure of the mitochondria of the cultured cortical cells of rat adrenals was studied. In vivo it was found that the zona fasciculata mitochondria have vesicular internal structure. 600-A vesicles appear free in the matrix or as protrusions of the inner mitochondrial membrane. In tissue cultures of the fetal and newborn rat adrenal cortex it was seen that ACTH induces transformation...

OBJECTIVE To investigate the abundance of metabolic proteins in adult and fetal human livers. METHODS Adult liver homogenate proteins, fetal liver homogenate proteins, adult liver mitochondrial proteins and fetal liver mitochondrial proteins were obtained from fetal or adult liver tissues and examined using the antibody microarrays containing 19 liver monoclonal mitochondrial antibodies. The ...
