The Af?ar section, situated in the Dombayova graben western Turkey, is one of key localities for study Pliocene Anatolia. Two fossiliferous layers yielded micromammal assemblages, including various cricetine and arvicoline species. These include species Mimomys cf. gracilis, Pliomys sp., Arvicolinae gen. sp. cricetines Cricetulus ehiki 1 hassiacus, M. graecus Mesocricetus primitivus 2. cooccure...

Chromatin from two Syrian hamster tissues: the Kirkman-Robbins hepatoma and the liver, has been separated into soluble (S) and insoluble (P) fractions. Both fractions contain the complete set of five main histones but differ in respect of HI subfractions. The hepatoma chromatin is known to contain an unusual HI subfraction, HI slow [12, 13], probably identical with a similar subfration present ...

Abstract The COVID-19 pandemic progresses unabated in many regions of the world. An effective antiviral against SARS-CoV-2 that could be administered orally for use following high-risk exposure would substantial benefit controlling pandemic. Herein, we show MK-4482, an nucleoside analog, inhibits replication Syrian hamster model. inhibitory effect MK-4482 on is observed animals when drug either...

Das Java-Hamster-Modell ist ein spezielles didaktisches Modell zum spielerischen Erlernen der Programmierung. Programmieranfänger lernen die grundlegenden Programmierkonzepte und den Programmentwurf kennen, indem sie so genannte Hamster-Programme entwickeln, mit denen sie virtuelle Hamster durch virtuelle Landschaften steuern und dabei bestimmte Aufgaben lösen lassen. Die Programmierkonzepte we...

Endotoxin was demonstrated not to act as an adjuvant in the primary antibody response in the Syrian hamster. Minimal adjuvant action was demonstrable in antibody formation to a second injection of bovine gamma globulin. The immunological status of the hamster towards the endotoxin did not alter this weak adjuvant action. It was confirmed that the antimitotic drug colchicine will act as an adjuv...

The feeding time for sand fly females was determined experimentally by feeding of thirty females (3-5 days-old) sand fly Phlebotomus papatasi on different blood sources (human, pigeon, hamster and blab C mice). Mean feeding time was longest on blab C mice, 8.55 minutes, followed by hamster, 7.05 minutes, then pigeon, 4.84minutes, and finally human, 4.69 minutes. Significant difference was obser...

We demonstrated that Demodex canis was transferred to skin xenografts of a dog and a hamster onto severe combined immunodeficiency mice. After the transfer of mites, the number of eggs, larvae, nymphs and adult mites per gram of canine and hamster xenografts increased, whereas no live mites were detected on murine allograft. These results indicate that D. canis proliferates in hair follicles of...

A cDNA encoding alpha-class glutathione S-transferase Yc (GSTYc) has been isolated from a Syrian hamster kidney library, and its nucleotide sequence (968 bp) has been determined. Analysis of the deduced amino acid sequence revealed a high level of identity between Syrian hamster GSTYc, rat GST Yc1 and Yc2 and mouse GSTYc. Northern-blot experiments demonstrated that Syrian hamster GSTYc expressi...

Neuroblastoma cells had a much higher rate of glycolysis than the Chinese hamster ovary Kl cells, although the former cell type had a longer doubling time (24 hr) than did the latter (12 hr). DL-Glyceraldehyde inhibited the glycolysis in both cell types to the same extent, but it reduced the growth of neuroblastoma cells more markedly than that of Chinese hamster ovary Kl cells. These data indi...

When chick erythrocytes were fused with adenine-requiring mutants of Chinese hamster cells of two different complementation classes and grown in adenine-free medium for 1 week or longer, mitotic cells were observed containing both chick and Chinese hamster metaphase chromosomes within a single cell. Stable hybrid clones were subsequently isolated that possessed, in addition to a complete Chines...
