The complete genome of Trichoplusia ni ascovirus 6b (TnAV-6b) was sequenced for the first time. The TnAV-6b isolate, which has its closest phylogenetic relationship with the TnAV-6a isolate, has a circular genome of 185,664 bp, with a G+C content of 46.0% and 178 predicted open reading frames.

BACKGROUND As an Agrobacterium tumefaciens T-DNA oncogene, T-6b induces the development of tumors and the enation syndrome in vegetative tissues of transgenic plants. Most of these effects are related to increases in soluble sugar contents. To verify the potential roles of T-6b in the distribution of carbon in developing seeds, not in vegetative tissues, we fused an endosperm-specific promoter ...

A series of novel 1[5"-(2"'-substituted phenyl)-4",5"'-dihydro isoxazole-3"-yl]-3-[(4 substituted phenyl)imino]1-3-dihydro-2H-indole-2-one were synthesized from different substituted chalconised indole-2,3-dione was prepared from the different chalconised Isatin. The structures of the compounds were elucidated by elemental and spectral (IR, (1)H NMR, and MS) analysis. The synthesized compounds ...

Vitamin D3 (1) is metabolized by various cytochrome P450 (CYP) enzymes, resulting in the formation of diverse metabolites. Among them, 4α,25-dihydroxyvitamin (6a) and 4β,25-dihydroxyvitamin (6b) are both produced from 25-hydroxyvitamin (2) CYP3A4. However, 6b detectable serum, whereas 6a not. We hypothesized that reason for this a difference susceptibility to CYP24A1-mediated metabolism. Here, ...

The replication of herpes simplex virus (HSV) type 1 in Vero cells is inhibited in the presence of (22S,23S)-3 -bromo-5 ,22,23-trihydroxystigmastan-6-one (6b), a synthetic brassinosteroid derivative. Attempts to disclose the mode of action of 6b indicate that a late step of virus multiplication is affected. In the presence of 6b, HSV late protein synthesis was severely diminished and this inhib...

In this multicenter study, 621 sets of blood culture specimens were drawn from 280 patients who were suspected of being septic and who were receiving antimicrobial therapy. Equal volumes of each specimen were inoculated into BACTEC 6B and 16B media. The 16B medium contained adsorbent and cationic resins for neutralizing the effects of the drugs. Of the 621 sets drawn, there were 72 positive cul...

Infection with human herpesvirus (HHV)-6B alters cell cycle progression and stabilizes tumor suppressor protein p53. In this study, we have analyzed the activity of p53 after stimulation with p53-dependent and -independent DNA damaging agents during HHV-6B infection. Microarray analysis, Western blotting and confocal microscopy demonstrated that HHV-6B-infected cells were resistant to p53-depen...

The antiviral mode of action of the synthetic brassinosteroid (22S,23S)-3beta-bromo-5alpha,22,23-trihydroxystigmastan-6-one (6b) against Junin virus replication in Vero cells was investigated. Time-related experiments showed that 6b mainly affects an early event of virus growth cycle. Neither adsorption nor internalization of viral particles was the target of the inhibitory action. The analysis...
