Production of corticosteroids from the adrenal gland is a multistep process in which corticosterone is enzymatically processed from its precursor cholesterol. The main hormone regulating the production of corticosterone is the proopiomelanocortin (POMC)-derived adrenocorticotropic hormone (ACTH). Adrenals of POMC-deficient (POMC(-/-)) mice do not produce corticosterone either at basal levels or...
the impact of price changes (at a level of market) on the other market levels (transfer of prices) will affect welfare of producers, marketing agents as well as consumers. in this study, asymmetric tea market is investigated through an application of johansen co-integration analysis and error correction model (ecm model) to time series of 1976-2009. co integration method used in the import mark...
This paper aims to determine the optimum price of electricity during restructuring process. We maximized social welfare function subject to market equilibrium, maximum production capacity of each group of power plants, maximum demand of each consumer type and the potential of electricity export and import. The model was run using 2007 monthly and annual data by means of GAMS optimization softwa...
The molecular mechanisms of peroxisome biogenesis have begun to emerge; in contrast, relatively little is known about how the organelle functions as cells age. In this report, we characterize age-related changes in peroxisomes of human cells. We show that aging compromises peroxisomal targeting signal 1 (PTS1) protein import, affecting in particular the critical antioxidant enzyme catalase. The...
The TIM22 complex, required for the insertion of imported polytopic proteins into the mitochondrial inner membrane, contains the nonessential Tim18p subunit. To learn more about the function of Tim18p, we screened for high-copy suppressors of the inability of tim18Delta mutants to live without mitochondrial DNA (mtDNA). We identified several genes encoding cytosolic proteins, including CCT6, SS...
