We calculate the average nucleon-nucleus potential from the Dirac-Hartree model, extended to positive energy. The sole input is a one-boson-exchange nucleon-nucleon interaction which reproduces ground-state properties. We obtain fair agreement with empirical values. Between 170 and 400 MeV, the calculated potential is repulsive in the nuclear interior but still attractive at the surface. This shape is related to the scalar and vector nature of the exchanged bosons. [less ▲]

Baryon-to-meson Transition Distribution Amplitudes (TDAs) appear as building blocks in the collinear factorized description of amplitudes for a class of hard exclusive reactions, prominent examples being hard exclusive pion electroproduction off a nucleon in the backward region and baryon-antibaryon annihilation into a pion and a lepton pair or a charmonium. Baryon-to-meson TDAs extend both the concepts of generalized parton distributions (GPDs) and baryon distribution amplitudes (DAs) encoding valuable complementary information on the hadronic structure. We review the basic properties of baryon-to-meson TDAs and discuss the perspectives for the experimental access with the PANDA detector. [less ▲]

Asymmetric nucleophilic synthesis of 6-[F-18]fluoro-L-dopa was investigated in order to reach an enantiomeric excess of close to 100% of the L form of this amino acid. The radiochemical synthesis required [F-18]fluoride as fluorinating agent and regioselective nucleophilic substitution of commercially available 6-nitroveratraldehyde. The [F-18]fluorobenzaldehyde thus obtained was easily converted to the corresponding 2-[F-18]fluoro-4,5-dimethoxybenzyl bromide. This alkylating agent was added to the lithium enolates of 1-(S)-(-)camphor imine of t-butyl glycinate (1) and (S)-(-)- 1 -Boc-2-t-butyl-3-methyl-4-imidazolidinone [(S)- Boc-BMI] (2) in order to compare the enantiomeric excess of the L form obtained in each case with these two chiral inductors. The L-isomer of fluorodopa was isolated after H1 hydrolysis and HPLC purification in 5-10% radiochemical yield (decay corrected). The overall synthesis time was of 110 min. Through this synthetic pathway, the L-isomer of fluorodopa was obtained in 83% e.e with 1 and 96% e.e with 2 respectively, as determined by chiral HPLC. A practical three step preparative scale synthesis of 6-[F-19]fluoro-D,L-dopa is also presented. [less ▲]

In summary, a general approach is presented to purify and sequence DNA fragments of a specific gene starting with a heterogeneous mixture of mRNAs. The methodology has been applied to the determination of the DNA sequence of a portion of the gene for human chorionic somatomammotropin. Most of the possible translation codons of the genetic code were found to be used. Some selectivity in the codon choices was found, and this may be important for RNA or gene regulation or structure. The stop codon UAG was found and a second stop codon in the same reading frame was found nine bases farther down. Finally, a "palindrome" sequence was detected in the 3' noncoding region. [less ▲]

A novel purification procedure for DNA complementary to individual mRNA species has been developed by using restriction endonuclease cleavage of cDNA transcribed from a complex mixture of mRNAs. This procedure has allowed us to isolate and analyze DNA fragments complementary to the mRNA coding for the human peptide hormone chorionic somatomammotropin (HCS). The mRNA for this hormone is a major constituent of placental polyadenylated RNA as shown by in vitro translation of placental RNA and by nucleic acid hybridization using HCS cDNA as a specific probe. The purification of HCS cDNA was achieved by Hae III and Hha I restriction endonuclease cleavage of single-stranded cDNA synthesized in vitro from total polyadenylated placental RNA. Polyacrylamide gel electrophoresis of the products allowed detection and purification of discrete DNA fragments. A comparison of the nucleotide sequence of these fragments with that predicted from the amino acid sequence of HCS demonstrated that the fragments are transcripts of HCS mRNA, containing most of the translated and 3′ untranslated regions. The latter region is characterized by a UAG termination codon immediately adjacent to the translated region (a second in phase UAG occurs 9 nucleotides away) and a palindromic sequence (GUGACCCCUCCCCAGUG) centered 27 nucleotides from the termination codon. The purification scheme outlined for HCS cCNA should be applicable to DNA sequences complementary to mRNA species which represent at least 2% of any polyadenylated RNA preparation. This was demonstrated by restriction endonuclease cleavage of cDNA synthesized from a mixture of purified rabbit globin and total polyadenylated human placental RNAs. [less ▲]

The nucleotide sequence of the cytopathic Osloss isolate of bovine viral diarrhoea virus (BVDV) was deduced from overlapping cDNA clones and from PCR products. The Osloss genome is an RNA molecule of positive polarity containing 12480 nucleotides and having the capacity to code for a polyprotein of 3975 amino acids. The presence of the previously described internal stop codon in this viral sequence was disproved after direct sequencing of the appropriate PCR-amplified fragment. Except for the previously reported insertion of a sequence coding for a ubiquitin-like protein, the viral genome shares great similarity with those of three other strains of the pestivirus genus. Computer-assisted sequence analyses and comparisons of known pestiviral genomic sequences led us to identify selected PCR primers in the 5' untranslated region. These primers were used successfully to amplify 18 distinct pestivirus isolates and potential DNA probes were noted from the deduced sequences. The possible use of a well conserved 26 base fragment as a diagnostic probe was confirmed in hybridization experiments. The 5' untranslated region was further studied and compared with those of other members of the Flaviviridae family, which includes the flaviviruses and the hepatitis C virus group. These sequence analyses support the possibility of discrimination amongst the closely related ruminant pestiviruses, border disease virus and BVDV. [less ▲]
