BACKGROUND Cervical cancer is necessarily caused by human papillomaviruses, which encode three oncogenes manifesting their functions by interfering with a number of cellular proteins and pathways: the E5, E6, and E7 proteins. We have earlier found in our microarray studies that the E5 oncogene crucially affects the expression of cellular genes involved in adhesion and motility of epithelial cel...

In this paper, we decode the PRN codes of the E5a and E5b signals broadcast by the Galileo GIOVE-A test satellite. The Galileo E5 band overlaps with Distance Measuring Equipment (DME) and Tactical Air Navigation (TACAN) bands. These navigation systems emit high-power pulses, causing severe interference to E5 signals and thus challenging the decoding process. We apply the 1.8 meter dish of the S...

BACKGROUND Despite the powerful impact in recent years of gene expression markers like the green fluorescent protein (GFP) to link the expression of recombinant protein for selection of high producers, there is a strong incentive to develop rapid and efficient methods for isolating mammalian cell clones secreting high levels of marker-free recombinant proteins. Recently, a method combining cell...

An experiment was conducted to determine the effect of lycopene on lipid profile and quality of meat of broiler chickens Ross 308 at a different form of selenium. 540 broiler cockerels were randomly divided into 6 groups: without lycopene supplement (groups C and E3), supplemented with 50 mg/kg lycopene (groups E1 and E4), supplemented with 100 mg/kg lycopene (groups E2 and E5) while the source...

The human nonmuscle myosin heavy chain B gene contains a 30-nucleotide alternative exon, N30, that is included in the mRNA from neural cells but is skipped in all other cells. We have previously identified an intronic distal downstream enhancer (IDDE) region that is required for neural cell-specific inclusion of N30. In this study, we investigated the mechanism by which the IDDE promotes N30 ex...

Papillomaviruses (PV) are double-stranded DNA viruses that can cause benignant and malignant tumors in amniotes. There are 13 types of bovine papillomavirus (BPV-1 to -13); they have been found in reproductive tissues and body fluids. Normally these viruses are detected in epithelial tissue. We looked for BPV in the blood of healthy cattle and cattle with papillomatosis, using PCR and RT-PCR. B...
