Conserved hypothetical BB0462 protein enhances the transcription activity of oppAV promoter
      
Borrelia burgdorferi BB0462 ORF encodes an unknown functional protein with 110 amino acids.
      
The co-transformation of BB0462 ORF and oppA upstream regulation DNA into E.
      
coli host cells and β-galactosidase activity assay demonstrated that the BB0462 protein enhanced the transcriptional activity of the oppAV promoter, but does not affect those of oppAI, II, III and IV promoters.
      
Analysis of DNA retardation and competitive repression also confirmed that the BB0462 protein bound to the 409 bp upstream regulation DNA fragment close to the initiation codon of the oppAV gene.
      
All data in our study suggested that the BB0462 protein was involved in the transcriptional regulation of the oppAV gene
      
The results were compared with those of brain type creatine kinase (CK-BB) and dithio-bis(succinimidyl propionate) cross-linked CK-MM.
      
CK-BB differed greatly in its distribution of aromatic amino acids in each domain and the unfolding process of cross-linked CK-MM was not accompanied by the dissociation of the dimer.
      
The aim of this study was to evaluate how growth factors (PDGF-BB, EGF, and TGF-1β) modulate hyaluronan synthase (HAS) activities in normal or stressed cultured human skin fibroblasts.
      
PDGF-BB induced HAS mRNA expression, protein synthesis, and HA production more efficiently than EGF and TGF-1β.
      
In addition, TGF-1β reduced the expression and synthesis of HAS3, while PDGF-BB and EGF had the opposite effect.
      
An unbounded flow of an ideal incompressible fluid flows around a plate BB' placed at right angles to the velocity vector of the flow at infinity.
      
Characteristics of the neutron field at the core center in the ИBB-2M water-moderated water-cooled reactor
      
The neutron spectrum has been measured at the center of the core in the ИBB-2M research water-moderated water-cooled reactor.
      
The kinetics of ignition of O2-O3 mixtures upon the excitation of O3 molecules by laser radiation with a wavelength #x03BB;I of 9.695 μm is considered.

In the pelagic zone of the Barents Sea, the biomass of mesozooplankton (Bz) was comparable with that of bacterioplankton (Bb = 39-175 mg/m3), the Bb/Bz ratio being 1.4-4.6.
      
Off the Varandeiskii, Pechora, and Kolguyev oil terminals, Bb increased to 155-300 mg/m3 and the Bb/Bz ratio rose to 1.4 to 50.3 (with an average value of 20.9), presumably due to the severe anthropogenic impact on these waters.
      
Bacteria of the genera Rathayibacter and Agreia synthesize three oxidases, the bb3- and aa3-type cytochrome oxidases and nonheme cyanide-resistant oxidase, in proportions dependent on the cultivation conditions and the growth phase.
      
The nascent fragment C4b is covalently bound to the target activator; C4Ab binds better to the target protein (immunoglobulin), and C4Bb to the target carbohydrate (liposaccharide).
