The application arises because of a very strong homological property enjoyed by certain cell filtrations forq-permutation modules.
      
We show that on each Schubert cell, the corresponding Kostant harmonic form can be described using only data coming from the Bruhat Poisson structure.
      
We do this by using an explicit set of coordinates on the Schubert cell.
      
(iii) Yet other compounds, acting by novel mechanisms, have recently been identified as anti-HIV agents that seem worthy of further (pre)clinical development: cell receptor CD4 downmodulators (i.e.
      
The Histamine H4 receptor is expressed mainly on eosinophils and mast cells and has been shown to be involved in the chemotaxis of both the cell types.
      
Fermentation broth and cell extracts were tested against typed test organisms.
      
The cell extract showed activity against Candida albicans, Aspergillus niger, Trichoderma viridae, Fusarium moniliforme and Alternaria brassicicola.
      
Berberine taken for the cytotoxic evaluatin was obtained through cell suspension cultures established from young green leaf segments.
      
Methanol extracts demonstrated better inhibitory effects on cultured L929 cells followed by purified berberine from cell suspension cultures and water extracts.
      
In this study, we find that prodigiosin could effectively inhibit the proliferation of human pancreatic cancer cells H8898 in a dose-and-time-dependent manner, with an IC50 of 75μmol according to the results of MTT and cell proliferation assays.
      
This inhibitive effect may relate to two factors: mitotic arrest and cell death.
      
Results of clone formation and Flow cytometry analysis (FCAS) suggested that prodigiosin has the capability of restraining mitosis by regulating the cell cycle.
      
All these results demonstrate that prodigiosin can obviously inhibit the proliferation of pancreatic cancer cells H8898 by arresting the cell cycle and inducing apoptosis.
      
A new series of 1,2,3-trisubstituted 2-(2-oxoalkyl)-2,3-dihydrobezimidazoles have been synthesized and evaluated for their cytotoxic activity using one normal (FL) and two cancer (RD and A2058) cell lines.
      
Compounds 4-21 were evaluated for cytotoxic activity against a panel NCI-H460 (lung), MCF7 (breast) and SF-268 (CNS) cancer cell lines.
      
32% or less, have been evaluated in a full panel of 60 human cancer cell lines over a 5-log dose range at the National Cancer Institute.
      
Several compounds have demonstrated growth inhibitory effects (GI50) in a wide range of cancer cell lines.
      
All compounds studied are significantly active in the RNA-dependent DNA-polymerase (RDDP) assay, and were not toxic toward the Vero cell line.
      
With regard to sensitivity, compounds 8f and 9c, f have proved to possess a remarkable activity against leukemia tumor cell lines (GI50?=?3.43-5.03?μM).
      
Indeed, compound 13c showed the highest activity profile against individual leukemia subpanel cell line SR (GI50?=?0.91?μM).
