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 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...

"Operationalizing C2 Agility" is the process of moving from a conceptual model or theory of C2 Agility to applying this theory to improve an entity’s C2 Agility in practice. This process is greatly facilitated if one builds a proper foundation. In this paper, we begin by identifying the critical elements or cornerstones of such a foundation and the role they play in enabling an entity to system...

Let c be a constant and (e1, f1), (e2, f2), . . . , (ecn, fcn) be a sequence of ordered pairs of edges from the complete graph Kn chosen uniformly and independently at random. We prove that there exists a constant c2 such that if c > c2 then whp every graph which contains at least one edge from each ordered pair (ei, fi) has a component of size Ω(n) and if c < c2 then whp there is a graph conta...

Many proteins involved in signal transduction and vesicle trafficking contain C2 domains whose membrane association is often regulated by calcium. Here, finite-difference Poisson-Boltzmann calculations are used to describe the electrostatic interactions between C2 domains of known structure and phospholipid membranes. The results explain how calcium binding can drive the association of some C2 ...

Introduction Posterior C1-C2 fusion is a highly successful treatment for atlantoaxial instability and other pathologies of the cervical spine, with fusion rates approaching 95%-100%. However, poor visualization of the lateral masses of C1 secondary to the course of the C2 nerve root along with blood loss from the venous plexus and compression of the C2 nerve from lateral mass screws are technic...

Fasting gluconeogenesis (GNG) is often quantified using the 2H2O technique, which is based on plasma 2H2O enrichment and ensuing enrichment of plasma glucose at the C5 and C2 positions. Fractional (fr)GNG can be calculated using the ratio of C5 to C2 enrichment or the ratio of C5 to plasma 2H2O enrichment. For the latter, equilibration of 2H2O and C2 is required. The optimal equilibration perio...

1. The owner of the private key does not know the value of m such that C1 = sm(a, b) and C2 = s −m(a, b), and thus he/she can not compute L(C1, C2). 2. If sλ(a, b) = 3 modulo n , then L(a, b) is not invertible modulo n. It follows that the owner of the private key can not decrypt the cipher C = (C1, C2) since he/she can not compute L(C1,C2) L(a,b) . In this short note, in order to decrypt the c...
