Understanding the nature of species" boundaries is a fundamental question in evolutionary biology. The availability of genomes from several species of the genus Aspergillus allows us for the first time to examine the demarcation of fungal species at the whole-genome level. Here, we examine four case studies, two of which involve intraspecific comparisons,(More)
Coptotermes formosanus is one of the most destructive wood-feeding termites. To understand the molecular mechanisms that regulate the development of the termite, a normalized C. formosanus cDNA library was constructed using mixed RNA isolated from workers, soldiers, nymphs and alates of both sexes. The sequencing of this library generated 131 636 expressed(More)
Highly pathogenic avian influenza (HPAI) virus subtype H5N1 has recently caused extensive epizootics in different regions of the world and presents a serious threat to man. Since 2005, HPAI virus subtype H5N1 strains have been circulating in Russia, which differ from the earlier isolated Southern Asia strains. A panel from 15 monoclonal antibodies (Mabs) to(More)
While the early start and higher intensity of the 2012/13 influenza A virus (IAV) epidemic was not unprecedented, it was the first IAV epidemic season since the 2009 H1N1 influenza pandemic where the H3N2 subtype predominated. We directly sequenced the genomes of 154 H3N2 clinical specimens collected throughout the epidemic to better understand the(More)
Two nuclear genes, RTG1 and RTG2, which sense the functional state of yeast mitochondria, have been described recently. Yeast strains with null alleles of either of these two genes (delta rtg1, delta rtg2) cannot grow on acetate as the sole carbon source and are auxotrophic for glutamate and aspartate. We report here a series of metabolic experiments and(More)
Cytomegalovirus (CMV) infection of human diploid embryo fibroblasts in vitro causes a massive cell death on the 3-4th day of infection with a high primary infection coefficient (1-5 U/cell). Cytopathological effects of viral infection on the 3-4th day includes diminishes of the cell size, changes in their form, compaction of the nuclear chromatin, and(More)
Cytomegalovirus (CMV) infection development and mRNA fas transcription levels (CD95) in resting (GO) and proliferating (S-phase) human lung embryo fibroblasts (HLEF-110044 line) were studied. In GO cells accumulation of infectious CMV was high and cell death was very quick, and fas gene expression was inhibited in early period of infection. In cells(More)
The effect of cytomegalovirus on the cell cycle was studied autoradiographically in an asynchronous culture of human diploid fibroblasts. The analysis of labeled mitosis showed that some cells infected in the S phase ceased to progress through the cell cycle at one of its phases (S, G2, or M); at the same time, at least part of infected cells remained(More)
Gonarthritis complicated by synovitis was treated by cryo-ultrasound or cryo-magnetotherapy in combination with therapeutic exercise. The comparison of the response has shown that both complexes are highly effective. In the absence of concomitant diseases and contraindications to ultrasound it is better to use cryo-ultrasound and exercise, otherwise(More)
