Parkin, an E3 ubiquitin ligase, has been found to be responsible for autosomal recessive juvenile parkinsonism characterized primarily by selective loss of dopaminergic neurons with subsequent defects in movements. However, the molecular mechanisms underlying this neuron loss remain elusive. Here, we characterized Drosophila parkin loss-of-function mutants,(More)
The COSMOS simulator provides fast and accurate switch-level modeling of MOS digital circuits. It attains high performance by preprocessing the transistor network into a functionally equivalent Boolean representation. This description, produced by the symbolic analyzer ANAMOS, captures all aspects of switch-level networks including bidirectional(More)
The COSMOS symbolic fault simulator generates test sets for combinational and sequential MOS circuits represented at the switch level. All aspects of switch-level networks including bidirectional transistors, stored charge, different signal strengths, and indeterminate (<italic>X</italic>) logic values are captured. To generate tests for a circuit, the(More)
The performance of control and water-stressed 10-d-old wheat seedlings was compared. During short-term water stress (irrigation was withheld for 9 d), rates of photosynthesis and transpiration, stomatal conductance, and relative water content decreased whereas the proline content increased. Chloroplast proteins were extracted from the leaves, separated by(More)
Parkin is the most prevalent genetic factor in the onset of autosomal recessive juvenile parkinsonism (AR-JP), and mutations in parkin has been reported to cause motor defects, which result from dopamine deficiency caused by dopaminergic neuronal cell death. Activation of c-Jun N-terminal kinase (JNK) has also been implicated in neuronal cell death in(More)
DJ-1, a Parkinson's disease (PD)-associated gene, has been shown to protect against oxidative stress in Drosophila. However, the molecular mechanism underlying oxidative stress-induced phenotypes, including apoptosis, locomotive defects, and lethality, in DJ-1-deficient flies is not fully understood. Here we showed that Daxx-like protein (DLP), a Drosophila(More)
Amyloid-β-42 (Aβ42) has been implicated in the pathogenesis of Alzheimer's disease (AD). Neuronal Aβ42 expression induces apoptosis and decreases survival and locomotive activity in Drosophila. However, the mechanism by which Aβ42 induces these neuronal impairments is unclear. In this study, we investigated the underlying pathway in theses impairments. JNK(More)
Recent studies have shown that the expression of genes related to the synthesis of flavonoids, such as the phenylalanineammonia lyase (PAL), chalcone synthase (CHS), chalcone isomerase (CHI), and stilbene synthase (STS) genes were induced in response to different signaling molecules and Botrytis cinerea inoculation in grapevine leaves. Therefore, in the(More)
We demonstrate gigahertz electro-optic modulator fabricated on low temperature polysilicon using excimer laser annealing technique compatible with CMOS backend integration. Carrier injection modulation at 3 Gbps is achieved. These results open up an array of possibilities for silicon photonics including photonics on DRAM and on flexible substrates. A(More)
The human genome contains approximately 13 orphan cytochrome P450 (P450, CYP) genes, of which the apparent function or substrate has not been identified. However, they seem to possess their own biological relevance in some tissues or developmental stages. Here, we characterized the heterologously expressed CYP2W1, an orphan P450 enzyme. The recombinant(More)
