Mice were given injections of C-type particles extracted from the ascitic fluid of plasmacytoma-bearing mice. These particles, extracted from MOPC-315 tumor-bearing mice and injected into BALB/c mice, protected them against challenge with MOPC-315 tumor cells. The protection was dependent upon tumor cell dose; 66% survival was observed with a lethal dose of tumor cells. No protection was observ...

We construct a model for the quark mass and flavor mixing matrices, based on the hypothesis that the flavor weak eigenstates in the three families are distinguished by a spontaneously broken discrete Z6 chiral symmetry. In a leading partially symmetric approximation, the model accommodates the family mass spectra, with a CKM matrix that is exactly unity. Adding small asymmetries in first order ...

Minutes comprise > 50 phenotypically similar Drosophila mutations believed to affect ribosomal protein genes. Common traits of the Minute phenotype are short and thin bristles, slow development, and recessive lethality. To further investigate the proposed Minute to ribosomal protein correspondence, loss-of-function Minute mutations were induced by P-element mutagenesis. Here, we report a previo...

The purification, renewal and differentiation of native cardiac progenitors would form a mechanistic underpinning for unraveling steps for cardiac cell lineage formation, and their links to forms of congenital and adult cardiac diseases. Previously, we have reported the identification of isl1+ cardiac progenitors in postnatal rat, mouse and human myocardium (1). The discovery of native cardiobl...

     Turkeh Dareh pluton is outcrop in NW of Iran and it is one of the intrusions in Sanandaj-Sirjan zone. Shaped crystals of this pluton distinct oscillatory zoning narrow and close together zoning in zircons indicate parental magma richness of zirconium. Factors affecting the shape of the zircon crystals are the composition, possibly the temperature of the crystallization, water content in ma...

The deoxytetradecamer d(AAAACGACGGCCAG) has been shown to be an excellent universal primer for sequence determination of DNA cloned into the bacteriophage M13 mp7, mp8, and mp9 series. This new primer offers several advantages over others currently available and it has been used to define the cloning of Hinf I fragments of bacteriophage S13 DNA into the Eco RI site of M13 mp7, utilizing the hom...
