Intravenous injection of substance P (SP) increases renal nerve firing and heart rate in spontaneously hypertensive rats (SHRs) and Wistar-Kyoto rats (WKYs) by stimulating sympathetic ganglia. Blood pressure is increased in SHRs but lowered in WKYs. This study assesses the role of neurokinin-1 (NK(1)) receptors in mediating the ganglion actions of SP. Rats for functional studies were anesthetiz...

Gamma ray, density, sonic and core logs obtained from two boreholes drilled over a longwall panel in Southwestern (SW) Pennsylvania were analyzed for formation boundaries, log-derived porosities and densities and for rock elastic properties from sonic transit times. Gamma ray (GR) and density logs (DL) were analyzed using univariate statistical techniques and fractal statistics for similarity a...

Each Gr-functor of the type (φ, f) of a Gr-category of the type (Π, C) has the obstruction be an element k ∈ H(Π, C). When this obstruction vanishes, there exists a bijection between congruence classes of Gr-functors of the type (φ, f) and the cohomology group H(Π,C). Then the relation of Gr-category theory and the group extension problem can be established and used to prove that each Gr-catego...

BACKGROUND The relationship between male infertility and gr/gr deletions that remove multiple genes of the Y chromosome varies among countries and populations. The aim of this study was to investigate the association between gr/gr deletions and spermatogenic phenotype in fertile and infertile Japanese men. METHODS The subjects were screened by sequence-tagged site (STS) analysis to detect gr/...

Let n,k,r and t be positive integers, and let [n] = {1,2, . . . ,n}. A family G ⊂ 2[n] is called r-wise t-intersecting if |G1∩·· ·∩Gr| ≥ t holds for all G1, . . . ,Gr ∈ G . Let us define a typical r-wise t-intersecting family Gi(n,r, t) and its k-uniform subfamily Fi(n,k,r, t), where 0 ≤ i ≤ ⌊n−t r ⌋, as follows: Gi(n,r, t) = {G ⊂ [n] : |G∩ [t + ri]| ≥ t +(r−1)i}, Fi(n,k,r, t) = Gi(n,r, t)∩ ([n...
