In a complex nervous system, neuronal functional diversity is reflected in the wide variety of dendritic arbor shapes. Different neuronal classes are defined by class-specific transcription factor combinatorial codes. We show that the combination of the transcription factors Knot and Cut is particular to Drosophila class IV dendritic arborization (da)(More)
The EGFR/Ras/Raf/MEK/ERK pathway is a major pathway involved in the control of growth signals, cell survival and differentiation. Mutations of signaling components, such as EGFR (c-erbB1), Ras, and B-Raf, have been shown to play roles in the genesis of human cancer, while point mutation of ERK has not been reported. In this study, we present evidence for a(More)
In a human cancer cell line, we previously found a mutation in codon 322 of the extracellular signal-regulated kinase (ERK2E322K), the protein showed a faster migration when compared to wild-type in SDS-PAGE and constitutive phosphorylation. However, the reason for the faster migration, and the biochemical and biological properties of the mutation is(More)
Interactions between pathogens and host induce human disorders including periodontitis, disintegration of the tooth supporting tissues. Tannerella forsythia has been linked to the periodontitis and several cytopathic reagents have been found in the bacterium; however, its contribution to the disease remains unclear. Biochemical approach to explore the(More)
We studied factors that control chemoresistance to 6 head and neck squamous cell carcinoma cell lines carrying p53 mutations. Cell lines were chosen, based on the presence of EGFR amplifications, the presence of H-ras mutations, and the absence of either. WST-1 viability assays showed that, in response to etoposide, Ca922 was most sensitive, HOC313 most(More)
Diagnosis of Parkinson’s disease (PD) is a challenging problem for medical community. Typically characterized by tremor, PD occurs due to the loss of dopamine in the brain’s thalamic region that results in involuntary or oscillatory movement in the body. The early stage of the PD is referred as resting tremors, which appears when the muscles(More)
4 Abstract-Image intensification plays an important role in image processing and analysis. In this paper, an efficient image intensification method is proposed. In order to sustain and enhance image while enhancing relative pixel details, we propose an algorithm unreliable radiant and low contrast images. The proposed algorithm consists of three phases:(More)
Continuous monitoring of EEG is essential for the neurologist to detect the epileptic seizures that occur at various intervals. Since large volume of data need to be analyzed, visual analysis has been proven to be time consuming and subsequently automated detection techniques have gained importance in the recent years. For the biomedical research community,(More)
