Chiral extension of the standard model
The chiral extension of the minimal standard model makes quarks with two chiralities present parallely. Some interesting questions, such as the possibility that leptons are made of additional leptonic quarks a...

Overexpression of the yeast MCK1 protein kinase suppresses conditional mutations in centromere-binding protein genes CBF2 and CBF5
We find that overexpression in yeast of the yeast MCK1 gene, which encodes a meiosis and centromere regulatory kinase, suppresses the temperature-sensitive phenotype of certain mutations in essential centromere b...

Supersymmetrization of the chiral extension of the standard model
In this paper we investigate the supersymmetrization of the chiral extension of the standard model. It is proven that such a theory maintains many important characteristics of the original one, but the generat...

Concentrations of Soluble CD95 and CD8 Antigens in the Plasma and Levels of CD8+CD95+, CD8+CD38+, and CD4+CD95+ T Cells Are Markers for HIV-1 Infection and Clinical Status
Apoptosis mediated via the CD95 (FAS/APO-1) receptor is thought to play a role in the depletion of CD4+ T cells in HIV infection. In the present study expression of the CD95 antigen on lymphocyte subsets and t...

Novel oxylipins from the temperate red alga polyneura latissima: Evidence for an arachidonate 9(S)-lipoxygenase
The oxylipin chemistry of the temperate red alga Polyneura latissima has been investigated. The structures of three novel oxylipins, 8-[1′(Z),3′(Z),6′(Z)-dodecatriene-1′-oxyl-5(Z),7(E)-octadienoic acid, 7(S ...

Nitric oxide-mediated apoptosis of K-1735 melanoma cells is associated with downregulation of Bcl-2
Recent studies have shown that the treatment of nonmetastatic K-1735 murine melanoma cells with cytokines induces the production of nitric oxide (NO) and hence cell death. The purpose of this study was to dete...
