Calumenin is a multiple EF-hand Ca2+-binding protein located in endo/sarcoplasmic reticulum of mammalian tissues. In the present study, we cloned two rabbit calumenin isoforms (rabbit calumenin-1 and -2, GenBank Accession Nos. SY225335 and AY225336, respectively) by RT-PCR. Both isoforms contain a 19 aa N-terminal signal sequence, 6 EF-hand domains, and a(More)
Superoxide dismutase (SOD) catalyzes the dismutation of the biologically toxic superoxide anion into oxygen and hydrogen peroxide and is deployed by the immune system to kill invading microorganisms. Extracellular SOD (EC-SOD) is a copper- and zinc-containing glycoprotein found predominantly in the soluble extracellular compartment that consists of(More)
Background. Uncontrolled melanogenesis and wrinkle formation are an indication of photoaging. Our previous studies demonstrated that (Z)-5-(2,4-dihydroxybenzylidene)thiazolidine-2,4-dione (MHY498) inhibited tyrosinase activity and melanogenesis in vitro. Objective. To examine in vivo effects of MHY498 as an antiaging compound on UVB-induced melanogenesis(More)
In this paper, a frequency-domain joint maximum- likelihood (ML) estimation of channel and radio frequency (RF) chain responses is considered when noisy side information is available. The channel includes only transmit and receive antennas and radio propagation medium, while the RF chain includes transmitter (Tx) and receiver (Rx) RF chains. A side(More)
This study investigated the agonistic activity of magnesium lithospermate B (1), isolated from Salvia miltiorrhiza, on peroxisome proliferator-activated receptor (PPARβ/δ) and the expressions of collagen genes (COL1A1 and COL3A1) and transforming growth factor-β1 (TGF-β1) in models of skin aging. The action of compound 1 as a PPARβ/δ agonist was determined(More)
