We investigate the conjectured sufficiency of a condition for h-vectors (1, h1, h2, . . . , hd, 0) of regular d-dimensional triangulations. (The condition is already shown to be necessary in [2]). We first prove that the condition is sufficient when h1 ≥ h2 ≥ · · · ≥ hd. We then derive some new shellings of squeezed spheres and use them to prove that the condition is sufficient when d = 3. Fina...

1 Histamine and 2-methyl-histamine (H1-receptor agonist) caused dose-dependent increases in capillary permeability in albino mice, but 4-methyl-histamine (H2-receptor agonist) caused no significant increase. 2 Mepyramine (H1-receptor antagonist) blocked the histamine-induced increase in capillary permeability whereas burimamide (H2-receptor antagonist) produced no significant blockade of the hi...

Given bipartite graphs H1 and H2, the bipartite Ramsey number b(H1;H2) is the smallest integer b such that any subgraph G of the complete bipartite graph Kb,b, either G contains a copy of H1 or its complement relative to Kb,b contains a copy of H2. It is known that b(K2,2;K2,2) = 5, b(K2,3;K2,3) = 9, b(K2,4;K2,4) = 14 and b(K3,3;K3,3) = 17. In this paper we study the case H1 being even cycles a...

Antibodies directed against whole histone and purified lysine-rich histone H1 extracted f rom isolated macronuclei of the ciliate Tetrahymena were obtained and conjugated to fluorescein isothiocyanate. The fluorescein-antibody conjugates were used to directly label Tetrahymena cells. Both macroand micronuclei were visibly fluorescent in cells stained with anti-whole histone conjugate. However ,...

Purpose: We examined whether nm23-H1 is a prognostic factor of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Experimental Design: We studied 102 consecutive, untreated PTCL-NOS patients from 1998 to 2008. The expression of nm23-H1 and TIA-1 was studied by immunohistochemistry. Results: nm23-H1 was positive in 44.1% and TIA-1 in 78.4% of the PTCL-NOS patients. nm23-H1 expressio...

An immunoinhibitory role of B7 homologue 1 (B7-H1) expressed by non-T cells has been established; however, the function of B7-H1 expressed by T cells is not clear. Peak expression of B7-H1 on Ag-primed CD8 T cells was observed during the contraction phase of an immune response. Unexpectedly, B7-H1 blockade at this stage reduced the numbers of effector CD8 T cells, suggesting B7-H1 blocking Ab m...

The human has two relaxins, termed H1 and H2, both of which are biologically active and co-expressed in the decidua, placenta and prostate; in the corpus luteum, the main source of circulating relaxin, only the H2 form is expressed. The reasons for this differential expression of the relaxin genes are unknown. The possibility that their 3'-untranslated regions (UTRs) contribute to this differen...

We isolated and identified the glyceraldehyde-derived advanced glycation product (AGE) formed from glyceraldehyde and N(alpha)-acetylarginine. A major product was identified as N(alpha)-acetyl-N(delta)-(5-methyl-imidazolin-4-one-2-yl)-ornithine. The compound has been reported as methylglyoxal-derived AGE, MG-H1. This study suggests that MG-H1 is formed through both glyceraldehyde-related and me...

BACKGROUND Based on the metastatic route in lymph nodes from lung cancer, we investigated micrometastasis in the dissected lymph nodes by genetic analysis of keratin 19 and nm23-H1 (the expression of a tumor-metastatic suppressor gene) and evaluated the postoperative outcomes. METHODS Ten patients operated with lung cancer were 4 males and 6 females, who were stage IA; 2, stage IB; 3, stage I...
