Infection by human papillomavirus type 16 (HPV-16) has been linked to cervical cancer. The transcription of viral genes in HPV-16 is partially controlled by a number of cellular transcription factors. We have previously identified a novel cellular transcription factor, PEF-1, from its ability to interact with the long control region (LCR) of HPV-16. This factor has a molecular mass of about 110...

background and objectives: enteropathogenic escherichia coli (epec) divided into two groups typical and atypical (aspect). the main virulence genes are located in a pathogenicity island called lee ( locus of enterocyte effacement ). lee frequently inserted in trna genes of selc , pheu and phev in the bacterial chromosome. tepec and aepec strains have some differences in their pathogenicity. the...

The miscibility and phase behavior of hydrated binary mixtures of two N-acylethanolamines (NAEs), N-myristoylethanolamine (NMEA), and N-palmitoylethanolamine (NPEA), with the corresponding diacyl phosphatidylethanolamines (PEs), dimyristoylphosphatidylethanolamine (DMPE), and dipalmitoylphosphatidylethanolamine (DPPE), respectively, have been investigated by differential scanning calorimetry (D...

The photodissociation of I2 2 embedded in mass-selected I2 (Ar)n clusters (n56 – 20) was studied using femtosecond photoelectron spectroscopy. The Ã8←X̃ transition in the I22 chromophore was excited using a femtosecond pump pulse, and the subsequent dynamics were followed by photodetachment with a femtosecond probe pulse and measurement of the resulting photoelectron spectrum. In all clusters, d...

The photodissociation dynamics of I2 ~CO2)n(n54 – 16) clusters excited at 780 nm have been studied with femtosecond photoelectron spectroscopy ~FPES!. The range of cluster sizes spans the uncaged and fully-caged product limits for this reaction. We observe time scales for a variety of processes in these clusters, including dissociation of the I2 2 chromophore, solvation of the I fragment, the o...

We analyze the $^{16}\mathrm{C}+p$ and $^{16}\mathrm{C}+d$ reactions within four- five-body continuum discretized coupled channel method. The $^{16}\mathrm{C}$ nucleus is described by a $^{14}\mathrm{C}+n+n$ configuration in hyperspherical coordinates. This description reproduces fairly well several low-lying states. First we ${2}^{+}\ensuremath{\rightarrow}{0}^{+}\phantom{\rule{4pt}{0ex}}E2$ t...

Zero-point vibrationally averaged (rg 0 ) structures were computed at the PBE0/SDD/631G* level for the [Pt 35 Cln 37 Cl5-n(H2 18 O)]  (n=0-5), cis-Pt 35 Cln 37 Cl(4-n)(H2 18 O)(H2 16 O) (n=0-4), fac-[Pt 35 Cln 37 Cl(3-n)(H2 18 O)(H2 16 O)2]  (n=0-3), [Pt 35 Cln 37 Cl5-n( 16/18 OH)] 2 (n=0-5), cis-[Pt 35 Cln 37 Cl(4-n)( 16/18 OH)2] 2(n=0-4), fac-[Pt 35 Cln 37 Cl(3-n)( 16/18 OH)3]  (n=0-3), ...
