We report an ab initio study of Sb2S3, Sb2Se3, and Bi2S3 sesquichalcogenides at hydrostatic pressures up to 60 GPa. explore the possibility that C2/m, C2/c, disordered Im-3m, I4/mmm phases observed in with heavier cations, viz. Bi2Se3, Bi2Te3, Sb2Te3, could also be formed Bi2S3, as suggested from recent experiments. Our calculations show C2/c phase is not energetically favorable any three compo...

Traditionally recognized as an RNA splicing regulator, heterogeneous nuclear ribonucleoprotein C1/C2 (hnRNPC1/C2) can also bind to double-stranded DNA and function in trans as a vitamin D response element (VDRE)-binding protein. As such, hnRNPC1/C2 may couple transcription induced by the active form of vitamin D, 1,25-dihydroxyvitamin D (1,25(OH)2D) with subsequent RNA splicing. In MG63 osteobl...

Using the full-length and two engineered soluble forms (C1-C2 and Cla-C2) of type V adenylyl cyclase (ACV), we have investigated the role of an intramolecular interaction in ACV that modulates the ability of the alpha subunit of the stimulatory GTP-binding protein of AC (Gsalpha) to stimulate enzyme activity. Concentration-response curves with Gsalpha suggested the presence of high and low affi...

An identified histaminergic neuron, C2, in the marine mollusk Aplysia is a complex mechanoafferent which appears to contribute to the maintenance of food arousal by means of its synaptic connections to the metacerebral cell (MCC). Because C2 also has extensive synaptic outputs to neurons other than the MCC, we studied its possible motor functions. We identified several synaptic followers of C2 ...

Cervical spine radiographs are crowded with superimposed bony and soft-tissue structures that make interpretation difficu lt. In addition, there are many anatomic and projectional variants that have been described [1-6] . Knowledge of them is essential to distinguish the normal from the pathologic. We illustrate another pseudolesion , the C2 "target, " and provide a radiologic description and a...

For the mollusc Tritonia diomedea to generate its escape swim motor pattern, interneuron C2, a crucial member of the central pattern generator (CPG) for this rhythmic behavior, must fire repetitive bursts of action potentials. Yet, before swimming, repeated depolarizing current pulses injected into C2 at periods similar those in the swim motor program are incapable of mimicking the firing rate ...

The 4,4’-diphenylstilbenes, denoted by C and T for the cis and trans isomers, as well as T-. and T2-, were characterized spectroscopically and electrochemically. The disproportionation 2T-.,Na+ F! T + T2-,2Na+ has equilibrium constant in T H F 0.04, AH = 18.2 kcal/mol, and AS = 54 cal/mol-deg, and its rate constant is 9.0 X lo8 M-I s-l. The cis-trans isomerization was studied in T H F at ambien...

The dissociation constants for the binding of Rhodobacter capsulatus cytochrome c2 and its K93P mutant to the cytochrome bc1 complex embedded in a phospholipid bilayer were measured by plasmon waveguide resonance spectroscopy in the presence and absence of the inhibitor stigmatellin. The reduced form of cytochrome c2 strongly binds to reduced cytochrome bc1 (Kd = 0.02 microM) but binds much mor...
