MOTIVATION Phylogenies are increasingly used in all fields of medical and biological research. Because of the next generation sequencing revolution, datasets used for conducting phylogenetic analyses grow at an unprecedented pace. We present ExaML version 3, a dedicated production-level code for inferring phylogenies on whole-transcriptome and whole-genome(More)
The relative content of phosphatidylcholine is lower and that of sphingomyelin is higher in transplantable fast growing mouse hepatoma-22, thus decreasing their ratio approximately 2.5-fold versus normal liver. The ceramide content and the neutral sphingomyelinase activity is markedly higher (3- and 6.5-fold, respectively), whereas the acid sphingomyelinase(More)
Contents of sphingenine (sphingosine) and sphinganine were studied in sphingomyelins of transplantable mouse tumors (hepatoma-22, melanoma B16, Lewis lung carcinoma, intestine carcinoma) and rat nephroma RA. The content of sphinganine was increased in sphingomyelins of hepatoma-22 and nephroma RA compared to sphingomyelins of liver and kidneys. Significant(More)
A coordination complex cis-dichlorodiamminedihydroxoplatinum (IV) (oxoplatinum) was first synthesized in the USSR by Chugaev and Khlopin in 1927 [3]. Its marked antitumor properties were revealed by one of the authors of this article at the All-Union Cancer Research Center of the Academy of Medical Sciences of the USSR. The paper gives data on the(More)
—Phylogenetic inference is the process of reconstructing the evolutionary history of species based on their traits, nowadays mostly using molecular sequence data. Current state-of-the-art inference methods, like Bayesian and Maximum Likelihood (ML) inference, rely on the Phylogenetic Likelihood Function (PLF) as their computational core. Due to the large(More)
Molecular sequences in public databases are mostly annotated by the submitting authors without further validation. This procedure can generate erroneous taxonomic sequence labels. Mislabeled sequences are hard to identify, and they can induce downstream errors because new sequences are typically annotated using existing ones. Furthermore, taxonomic(More)
Contents of sphingolipids (ceramide, sphingomyelin, gangliosides) and the composition of their sphingoid bases were studied in the transplantable rat nephroma-RA and in rat kidneys. The content of sphingomyelin was about 1.3-fold decreased and the content of ceramide was about 1.4-fold increased in the nephroma compared to normal kidneys, and this(More)
Dihydroceramide desaturase activity in the transplantable mouse hepatoma-22, rat hepatoma-27, M1 sarcoma, and RS1 rat cholangiocellular carcinoma has been investigated. It was found that the dihydroceramide desaturase activity in mouse hepatoma-22 is lower than that in normal mouse liver. However, the activity of this enzyme in subcutaneously and(More)
The content of sphingolipids in M3 and B16/F10 melanomas with a high metastatic potential and in Claudman's and B16/F1 melanomas with a low metastatic potential was studied. It was shown that the content of total lipid-bound sialic acids and ganglioside GM3 in melanomas with a high metastatic potential is considerably higher than that in melanomas with a(More)
