Existence and uniqueness of Q-processes with a given finite μ-invariant measure

Let Q be a stable and conservative Q-matrix over a countable state space S consisting of an irreducible class C and a single absorbing state 0 that is accessible from C. Suppose that Q admits a finite mu-subinvariant measure in on C. We derive necessary and sufficient conditions for there to exist a Q-process for which m is mu-invariant on C, as well as a necessary condition for the uniqueness of such a process.

Three cases of Q fever osteomyelitis in children and a review of the literature

Q fever is a common zoonosis worldwide. Awareness of the disease and newer diagnostic modalities have resulted in increasing recognition of unusual manifestations. We report 3 cases of Q fever osteomyelitis in children and review the literature on 11 other reported cases. The cases demonstrate that Coxiella burnetii can cause granulomatous osteomyelitis that presents without systemic symptoms and frequently results in a chronic, relapsing, multifocal clinical course. Optimal selection and duration of antimicrobial therapy and methods of monitoring therapy are currently uncertain.

Tertiapin-Q blocks recombinant and native large conductance K+ channels in a use-dependent manner

Tertiapin, a short peptide from honey bee venom, has been reported to specifically block the inwardly rectifying K+ (Kir) channels, including G protein-coupled inwardly rectifying potassium channel (GIRK) 1 + GIRK4 heteromultimers and ROMK1 homomultimers. In the present study, the effects of a stable and functionally similar derivative of tertiapin, tertiapin-Q, were examined on recombinant human voltage-dependent Ca2+-activated large conductance K+ channel (BK or MaxiK; alpha-subunit or hSlo1 homomultimers) and mouse inwardly rectifying GIRK1 + GIRK2 (i.e., Kir3.1 and Kir3.2) heteromultimeric K+ channels expressed in Xenopus oocytes and in cultured newborn mouse dorsal root ganglion (DRG) neurons. In two-electrode voltage-clamped oocytes, tertiapin-Q (1-100 nM) inhibited BK-type K+ channels in a use- and concentration-dependent manner. We also confirmed the inhibition of recombinant GIRK1 + GIRK2 heteromultimers by tertiapin-Q, which had no effect on endogenous depolarization- and hyperpolarization-activated currents sensitive to extracellular divalent cations (Ca2+, Mg2+, Zn2+, and Ba2+) in defolliculated oocytes. In voltage-clamped DRG neurons, tertiapin-Q voltage- and use-dependently inhibited outwardly rectifying K+ currents, but Cs+-blocked hyperpolarization-activated inward currents including I-H were insensitive to tertiapin-Q, baclofen, barium, and zinc, suggesting absence of functional GIRK channels in the newborn. Under current-clamp conditions, tertiapin-Q blocked the action potential after hyperpolarization (AHP) and increased action potential duration in DRG neurons. Taken together, these results demonstrate that the blocking actions of tertiapin-Q are not specific to Kir channels and that the blockade of recombinant BK channels and native neuronal AHP currents is use-dependent. Inhibition of specific types of Kir and voltage-dependent Ca2+-activated K+ channels by tertiapin-Q at nanomolar range via different mechanisms may have implications in pain physiology and therapy.

On the existence of uni-instantaneous Q-processes with a given finite mu-invariant measure

Let S be a countable set and let Q = (q(ij), i, j is an element of S) be a conservative q-matrix over S with a single instantaneous state b. Suppose that we are given a real number mu >= 0 and a strictly positive probability measure m = (m(j), j is an element of S) such that Sigma(i is an element of S) m(i)q(ij) = -mu m(j), j 0 b. We prove that there exists a Q-process P(t) = (p(ij) (t), i, j E S) for which m is a mu-invariant measure, that is Sigma(i is an element of s) m(i)p(ij)(t) = e(-mu t)m(j), j is an element of S. We illustrate our results with reference to the Kolmogorov 'K 1' chain and a birth-death process with catastrophes and instantaneous resurrection.
