INTRODucnON Leprosy is caused in human by Mycobacterium leprae, since this organisms can not be cultivated in vitro and there is no suitable laboratory animal for the propagation of lepra bacillus, lepromin, usually prepared from the nodule (leproma) of the patient with clinieal form of lepromatosis leprosy, is used for the determination of allergic reactions (FERNANDEZ) and diagnosis of kind o...

We compute, for each genus g > 0, the generating function Lg ≡ Lg(t; p1, p2, . . . ) of (labelled) bipartite maps on the orientable surface of genus g, with control on all face degrees. We exhibit an explicit change of variables such that for each g, Lg is a rational function in the new variables, computable by an explicit recursion on the genus. The same holds for the generating function Fg of...

The implications arising from the “Schrödinger’s cat” thought experiment have led some authors to argue that observation of a measurement by a conscious observer is required to collapse quantum wave-functions. Here we combine Schrödinger’s experimental paradigm with a system for splitting the information about the quantum state between two observers, thereby allowing distinct outcomes to be rec...

Expressed metabotropic group 1 glutamate mGluR5 receptors and nucleotide P2Y1 receptors (P2Y1Rs) show promiscuous ion channel coupling in sympathetic neurons: their stimulation inhibits M-type [Kv7, K(M)] potassium currents and N-type (Ca(V)2.2) calcium currents (Kammermeier and Ikeda, 1999; Brown et al., 2000). These effects are mediated by G(q) and G(i/o) G-proteins, respectively. Via their C...
