Abstract: A process for the solid-phase synthesis of a peptide containing at least one retro-inverso amide bond characterized in that :
     a) the C-terminal partial peptide sequence up to the bond which has to be retro-inverted is synthesized by stepwise condensation of the amino acids suitably protected at the amino group as well as at the side chain functional groups, on a solid support which is insoluble in the reaction medium,   b) the dipeptide derivative of general formula (I) :
      wherein 
Fmoc is N-9-fluorenylmethoxycarbonyl, and 
R and R₁, each independently, represent the side-chain residues of natural amino acids wherein the functional groups, if any, are suitably protected, 
is coupled to the amino terminus of the partial peptide sequence covalently bound to the solid insoluble support,   c) the Fmoc amino-protecting group is cleaved from the peptide bound to the solid insoluble support,   d) the whole sequence of the desired retro-inverso peptide is then stepwise built up by conventional procedures   e) the thus obtained retro-inverso peptide is detached from the solid insoluble support and purified.

Abstract: The baculovirus-insect cell vector system is used as a high efficiency eukaryotic cloning and expression method for the production of recombinant proteins. A major application of this system is also in the development of rDNA vaccines for a variety of important human and animal diseases. This system is used to express a variety of candidate vaccine immunogens derived from the envelope gene of Human Immunodeficiency Virus (HIV). The envelope protein of HIV is the most promising candidate in the development of vaccines and diagnostics for AIDS since it has been shown that the envelope glycoprotein represents the major target antigen of AIDS virus. Recombinant baculoviruses have been constructed which express a variety of domains of the envelope gene ( env ), including gp 160 and gp 120. Expression of the recombinant HIV baculoviruses in insect cells results in the production of glycoproteins which are reactive with HIV-specific serum. HIV antigens produced from some of these recombinants have been successfully employed in a variety of immunodiagnostic assays including ELISA, Western Blotting and radioimmunoprecipitation.

Abstract: A marked reduction in the pressure drop of cooling liquid through a grid spacer of a nuclear fuel assembly is attained by convexly contouring the up­stream (usually the lower) edges (32) of the grid members. Preferably, they are made streamlined or semicylind­rical. This can be done by first beveling and then etching them, by directing a stream of mixture of abrasive and an organic polymer against them, or by traversing an electron or laser beam along them at a power and velocity such as to cause local melting. A lesser improvement is secured by beveling along. A still further improvement can be obtained by also tape­ring the downstream (usually upper) edges (34).
