where HJ = HJ(x, y, t) is a polynomial of x and y of which the coefficients are rational functions of t holomorphic in BJ := P−ΞJ , ΞJ 3 ∞ being the fixed singular points of the J-th Painlevé equation (Ref. 2). Here the equivalece means that the second order nonlinear differential equation in x obtained from the J-th Painlevé system by elimination of y is just the J-th Painlevé equation. The J-...

An agar medium with improved selection for Treponema hyodysenteriae was developed. Cultures of T. hyodysenteriae and T. innocens, feces from 11 clinically normal pigs, and colonic contents from 6 pigs with gross lesions consistent with swine dysentery were diluted in phosphate-buffered saline and plated on Trypticase soy agar (BBL Microbiology Systems, Cockeysville, Md.) with 5% citrated bovine...

Fecal material from pigs experimentally infected with Treponema hyodysenteriae was collected and inoculated on six different selective media to compare their abilities for recovery of T. hyodysenteriae. Additionally, various types of samples were compared to find the most appropriate for submitting material to laboratories. Isolation rates for T. hyodysenteriae were 89.7% on BJ medium, 88.3% on...

CD4+ T cells are essential in inflammation and autoimmune diseases. Interferon-γ (IFN-γ) secreting T helper (Th1) and IL-17 secreting T helper (Th17) cells are critical for several autoimmune diseases. To assess the inhibitory effect of a given compound on autoimmune disease, we screened many compounds with an in vitro Th differentiation assay. BJ-3105, a 6-alkoxypyridin-3-ol analog, inhibited ...

Given a set-comparison predicateP and given two lists of setsA = (A1, . . . , Am) and B = (B1, . . . , Bm), with all Ai, Bj ⊆ [n], the P-set join A ./P B is defined to be the set {(i, j) ∈ [n] × [n] | P(Ai, Bj)} ([n] denotes {1, 2, . . . , n}). When P(Ai, Bj) is the condition “Ai ∩ Bj 6= ∅” we call this the set-intersection-notempty join (a.k.a. the composition ofA and B); whenP(Ai, Bj) is “Ai∩...

The diversity of T-cell populations is determined by the spectrum of antigen-specific T-cell receptors (TCRs) that are heterodimers of alpha and beta subunits encoded by rearranged combinations of variable (AV and BV), joining (AJ and BJ), and constant region genes (AC and BC). We have developed a novel approach for analysis of beta transcript diversity in mice with a real-time PCR-based method...

Let t, n be integers with n ≥ 3t. For t ≥ 3, we prove that in any family of at least t4n2 ) triples from an n-element set X, there exist 2t triples A1, B1, A2, B2, . . . , At, Bt and distinct elements a, b ∈ X such that Ai ∩Aj = {a} and Bi ∩Bj = {b}, for all i 6= j, and Ai ∩Bj = { Ai − {a} = Bj − {b} for i = j ∅ for i 6= j. When t = 2, we improve the upper bound t ( n 2 ) to 3 ( n 2 ) + 6n. Thi...

Using a fixed point theorem of strict-set-contraction, we establish criteria for the existence of positive periodic solutions for the periodic neutral logistic equation, with distributed delays, x′(t) = x(t) h a(t)− n X i=1 ai(t) Z 0 −Ti x(t+θ) dμi(θ)− m X j=1 bj(t) Z 0 −T̂j x′(t+θ) dνj(θ) i , where the coefficients a, ai, bj are continuous and periodic functions, with the same period. The value...

The amino acids encoded at the junctions of T cell receptor (TCR) V and J genes directly interact with MHC bound peptides. However, the regulation of the human TCRBJ gene repertoire has been difficult to analyze, because of the potentially complex number of BJ gene rearrangements. To overcome this problem, we developed a PCR-ELISA method to study BJ gene expression, and compared peripheral T ly...
