Widespread adaptation of shared memory programming for High Performance Computing has been inhibited by a lack of standardization and the resulting portability problems between platforms and APIs. In this paper we present the HAMSTER framework, which helps overcome these problems via cross-platform support and easy retargetability to a wide range of programming models. HAMSTER currently support...

The cell culture lines HTG2 and HTG3 were established from a transplantable hamster tumor induced by a murine sarcoma virus (strain Gz-MSV) after 17 and 60 in vivo passages, respectively. The viruses released by these two cell lines markedly differ in morphology, antigenic composition, infectivity, transforming ability, and enzymatic activity. HTG2 virions contained the sarcoma genome but were ...

Hamster hepatocytes, like human hepatocytes, secrete triacylglycerol (TAG) as very-low-density lipoprotein (VLDL) in association with apolipoprotein (apo) B100, whereas in the rat, TAG is secreted predominantly in association with apoB48. Nevertheless, in hepatocytes from both species, a minimum of between 60% and 70% [69. 1+/-1.4% (hamster), 60.6+/-2.5% (rat)] of the VLDL TAG was secreted foll...

We examined the synthesis and accumulation of ribosomal RNA and protein in hybrid cells formed by fusing mouse 3T3 cells with Chinese hamster ovary cells resistant to the antibiotic emetine. These hybrid lines retained chromosomes of both parents and accumulated mouse and hamster ribosomal components in hybrid ribosomes. “he synthesis of precursor ribosomal RNA was found to vary from half-hamst...

The infection and multiplication of Toxoplasma gondii and Trypanosoma cruzi were compared in primary cultures of white rat, mouse and hamster astrocytes. These cells were cultured on cover slides and infected with T. gondii tachyzoites or T. cruzi blood trypomastigotes. Results show that hamster astrocytes are more susceptible to the multiplication of both parasites than rat and mouse cells. Th...

The nitric oxide radical (*NO) released from tobacco-related compounds induces DNA damage, protein modifications, and cellular toxicity through the formation of peroxynitrite (ONOO-), the reaction product of *NO and the oxygen radical, superoxide. We hypothesize that tobacco-related compounds are cytotoxic and induce quantifiable DNA single-strand breaks in immortalized hamster cheek pouch (POI...

Recombinant plasmids containing DNA inserts complementary to mRNA coding for hypoxanthine-guanine phosphoribosyltransferase (HPRT) from mouse and Chinese hamster cell lines have been isolated from cDNA libraries and characterized by DNA sequence analysis. A total of 1292 nucleotides of the mouse cDNA sequence and 1301 nucleotides of the Chinese hamster cDNA sequence has been determined. Each of...

Prototrophic hybrids formed from an adenine-requiring Chinese hamster cell and human fibroblasts uniformly display new esterase activity that differs from that of either parental cell in electrophoretic mobility and substrate specificity. The hybrids that grew in the selective medium and possessed the new esterase activity had a single extra chromosome that resembled a B-group human chromosome....
