The atom-bond connectivity (ABC) index of a graph (,) G V E is defined as () [ () () 2]/[ () ()] uv E ABC G d u d v d u d v  ¦ , where () d u denotes the degree of vertex u of G. This recently introduced molecular structure descriptor found interesting applications in the study of the thermodynamic stability of acyclic saturated hydrocarbons, and the(More)
— In this paper, we study the connectivity properties of a wireless sensor network from an information-theoretic viewpoint. We consider both regular linear (one-dimensional) and planar (two-dimensional) networks with unreliable sensor nodes, i.e., each node is inactive/dead with a certain probability. We study the following problems: 1) What is the(More)
Akt signaling plays a central role in many biological functions, such as cell proliferation and apoptosis. Because Akt (also known as protein kinase B) resides primarily in the cytosol, it is not known how these signaling molecules are recruited to the plasma membrane and subsequently activated by growth factor stimuli. We found that the protein kinase Akt(More)
In goldfish (Carassius auratus), two distinct forms of gonadotropin-releasing hormone (GnRH), namely, salmon GnRH (sGnRH) and chicken GnRH-II (cGnRH-II), have been identified in the brain using chromatographic, immunological, and molecular cloning approaches. These two native GnRHs act on specific receptors in the anterior pituitary to stimulate the(More)
Corticotropin-releasing factor (CRF) and urotensin I (UI) precursor cDNAs were cloned and sequenced from a goldfish brain cDNA library in order to investigate the distribution of CRF and UI mRNAs in goldfish brain and the regulation of CRF and UI gene expression. The CRF (966-bp) and UI (769-bp) cDNAs encode 163- and 146-amino acid precursors, respectively,(More)
Recently, we described the complete nucleotide sequence of cholecystokinin (CCK) mRNA and the deduced amino acid sequence of the precursor on the basis of molecular cloning and sequence analysis of cDNA from goldfish brain. In this study, we investigated the hypothesis that CCK has a role in feeding behavior by examining CCK gene expression in the brain of(More)
Three distinct somatostatin cDNAs characterized previously from goldfish brain encode three preprosomatostatins (PSS), designated as PSS-I, PSS-II and PSS-III. In this study, dopaminergic regulation of PSS gene expression was examined by Northern blot analysis in the forebrain of goldfish. Intraperitoneal injection of the non-selective dopamine (DA)(More)
In mammals, neuropeptide Y (NPY) is a potent orexigenic factor. In the present study, third brain ventricle (intracerebroventricular) injection of goldfish NPY (gNPY) caused a dose-dependent increase in food intake in goldfish, and intracerebroventricular administration of NPY Y1-receptor antagonist BIBP-3226 decreased food intake; the actions of gNPY were(More)
