Deterin, a new apoptosis inhibitor from Drosophila melanogaster, possesses an unusual structure of only a single baculovirus inhibitor of apoptosis (IAP)-type repeat and no RING finger motif. The biochemical actions of deterin are demonstrated in SF9 and S2 cell transfection assays, in which the expressed protein acts in the cytoplasm to inhibit or deter(More)
The subthalamic nucleus receives serotonergic projections from the dorsal raphe nucleus. However, the role of serotonergic innervation in the activity of subthalamic neurons in vivo is unknown. The aim of the present work is to study the changes in the firing of subthalamic neurons in rats with 5,7-dihydroxytryptamine lesions of the dorsal raphe nucleus and(More)

Hypocrellin A (HA), a perylene quinone derivative, is a new photosensitizer extracted from Hypocrella bambusae (B et Br) Sace. A high voltage sodium lamp was used as the light source; the illumination intensity was 105 mW/cm2. After HA 25 micrograms/ml and illumination for 10 min, mitochondrial ATPase and microsomal G-6-Pase of hepatoma cells were(More)
The identification of potential endogenous or synthetic ligands for orphan receptors in the steroid receptor superfamily is important both for discerning endogenous regulatory pathways and for designing receptor inhibitors. The insect nuclear receptor Ultraspiracle (USP), an ortholog of vertebrate RXR, has long been treated as an orphan receptor. We have(More)
Large volume HPGe detectors are commonly used in applications that require good energy resolution and high detection efficiency, but are expensive and difficult to grow. Clover detectors consisting of 4 smaller crystals in a common cryostat are a possible alternative, but traditionally require complex readout electronics. In contrast, the DGF Pixie-4 is a(More)
AIM To study if bepridil (Bep) could affect the enhancement of activity of cerebral mitochondria Ca2+ Mg(2+)-ATPase caused by levothyroxine (Lev) in relation to ischemic overload calcium cerebrum injury. METHODS The experimental hyperthyroidism model with ischemic cerebrum was developed in rats by ig Lev 1 mg.kg-1.d-1 for 7 d. Ca2+ Mg(2+)-ATPase activity(More)
Dihydroflavonol 4-reductase (DFR) genes from Rosa chinensis (Asn type) and Calibrachoa hybrida (Asp type), driven by a CaMV 35S promoter, were integrated into the petunia (Petunia hybrida) cultivar 9702. Exogenous DFR gene expression characteristics were similar to flower-color changes, and effects on anthocyanin concentration were observed in both types of(More)
Transcription from the core promoter of the juvenile hormone esterase gene (-61 to +28) requires the presence of both an AT-rich motif (TATA box) and an initiator motif for any transcription to occur, when assayed by either transcription in vitro with lepidopteran Sf9 nuclear extracts or by transient-transfection assay in Sf9 cells. Additional gel-shift(More)
