“…In human HIV-1 infection, an indicator of poor prognosis and imminent progression to full-blown AIDS is the loss of antibody to the major viral capsid antigen p24 (23). All three SIVA3-infected infant macaques exhibited a similar pattern of loss of antibody responsiveness to Gag (p26), predating the development of full-blown AIDS (Fig.…”

Adult macaques do not develop disease after infection with a nef deletion mutant of the simian immunodeficiency virus (SIV) and are protected against challenge with pathogenic virus. This finding led to the proposal to use nef-deleted viruses as live, attenuated vaccines to prevent human acquired immunodeficiency syndrome (AIDS). In contrast, neonatal macaques developed persistently high levels of viremia after oral exposure to and SIV nef, vpr, and negative regulatory element (NRE) deletion mutant. Severe hemolytic anemia, thrombocytopenia, and CD4+ T cell depletion were observed, indicating that neither nef nor vpr determine pathogenicity in neonates. Because such constructs have retained their pathogenic potential, they should not be used as candidate live, attenuated virus vaccines against human AIDS.

A constituent quark model is developed for an arbitrary light-cone direction so that the light-front time is x + LF = ω · x with a constant lightlike four-vector ω. Form factors are obtained from free one-body electromagnetic current matrix elements. They are found to be ωindependent for spin-0 mesons, nucleons and the Λ hyperon, while there is ω-dependence for spin-1 systems like the deuteron.

We focus on the potentialities of nucleon-antinucleon (NN) annihilation as a means of producing new mesonic states. The case for the existence of quasinuclear NN bound states is discussed in detail. Strong evidence for a 2 ++ (0 + ) state of this type has been obtained at LEAR in annihilation from the p-wave (L = 1) NN system, in support of earlier sightings of this object in L -0 annihilation at Brookhaven. In the next generation of LEAR experiments, the emphasis shifts to the search for mesons containing dynamical excitations of the gluonic field, namely glueballs and hybrids (QQg)-We discuss some features of the masses, decay branching ratios and production mechanisms for these states, and suggest particular NN annihilation channels which are optimal for their discovery.
