I The activity produced by intra-arterial bradykinin and prostaglandin El was investigated in multifibre strands dissected from the saphenous nerves of anaesthetized rats. 2 Bradykinin (0.5-10 gg) alone produced little activity in nerve strands but produced considerable activity following a 10 min infusion, but not a single injection, of prostaglandin E1 (5-100 ng). 3 Prostaglandin E1 alone pro...

Proof sketch. e sketch the main idea of the proof. Let = maxe∈E Reff(e). First we need to construct an isotropic set of vector. For any edge e ∈ E we let ve = L G be. It is easy to see that ∑ e∈E vev T e = I and ‖ve‖ = Reff(e). So, by the above theorem, the edges of G can be partitioned into two sets E1, E2 such that for j ∈ {1, 2}, (1/2−O( √ ))LG LEj (1/2 +O( √ ))LG. The left inequality implie...

The methionine salvage pathway allows the in vivo recovery of the methylthio moiety of methionine upon the formation of methylthioadenosine (MTA) from S-adenosylmethionine (SAM). The Fe(II)-containing form of acireductone dioxygenase (ARD) catalyzes the penultimate step in the pathway in Klebsiella oxytoca, the oxidative cleavage of the acireductone 1,2-dihydroxy-3-oxo-5-(methylthio)pent-1-ene ...

Imidazole, given intraperitoneally to rabbits, inhibited the prostaglandin E1-induced (PGE1) elevation of intraocular pressure. The maximum imidaz-le effect occurred at three to six hours after intraperitoneal infection. The prostaglandin E1-induced aqueous humor protein elevation was reduced markedly in the imidazole-pretreated rabbits. Intravenous administration of imidazole also was effectiv...

The hyperfine induced 2s2p P0, P2 → 2s 2 S0 E1 transition probabilities of Be-like ions were calculated using grasp2K based on multi-configuration Dirac-Fock method and HFST packages. It was found that the hyperfine quenching rates are strongly affected by the interference for low-Z Be-like ions, especially for 2s2p P0 → 2s2 S0 transition. In particular, the trends of interference effects with ...

In this paper we study the time complexity of the problem Simultaneous Embedding with Fixed Edges (Sefe), that takes two planar graphs G1 = (V,E1) and G2 = (V,E2) as input and asks whether a planar drawing Γ1 of G1 and a planar drawing Γ2 of G2 exist such that: (i) each vertex v ∈ V is mapped to the same point in Γ1 and in Γ2; (ii) every edge e ∈ E1 ∩ E2 is mapped to the same Jordan curve in Γ1...

Theorem 1.1. Let A be a semisimple complex Banach algebra with the following properties: (i) for every closed right ideal R in A, there exists a closed left ideal L such that R∩L= {0} and R+ L= A (each a∈ A can be written in the form a= a1 + a2 with a1 ∈ R, a2 ∈ L); (ii) if a,b in A are such that ab = ba= 0, then ‖a+ b‖2 = ‖a‖2 +‖b‖2. Then A is a commutative proper H∗-algebra [1]. It is easy to...

Let E be an elliptic curve defined over the rationals. For any prime p of good reduction, let Ep be the elliptic curve over Fp obtained by reducing E mod p. Let ap(E) be the trace of the Frobenius morphism of Ep. Then, Hasse proved that #E(Fp) = p + 1 − ap(E) with |ap(E)| ≤ 2 √ p. The case ap(E) = 0 corresponds to supersingular reduction mod p. Let N be a positive integer. For a fixed r ∈ Z, an...

KCNE1 (E1) β-subunits assemble with KCNQ1 (Q1) voltage-gated K(+) channel α-subunits to form IKslow (IKs) channels in the heart and ear. The number of E1 subunits in IKs channels has been an issue of ongoing debate. Here, we use single-molecule spectroscopy to demonstrate that surface IKs channels with human subunits contain two E1 and four Q1 subunits. This stoichiometry does not vary. Thus, I...
