Abstract: The invention provides a method for obtaining a broadly neutralizing antibody (bNab), including screening memory B cell cultures from a donor PBMC sample for neutralization activity against a plurality of HIV-1 species, cloning a memory B cell that exhibits broad neutralization activity; and rescuing a monoclonal antibody from that memory B cell culture. The resultant monoclonal antibodies may be characterized by their ability to selectively bind epitopes from the Env proteins in native or monomeric form, as well as to inhibit infection of HIV-1 species from a plurality of clades. Compositions containing human monoclonal anti-HIV antibodies used for prophylaxis, diagnosis and treatment of HIV infection are provided. Methods for generating such antibodies by immunization using epitopes from conserved regions within the variable loops of gp120 are provided. Immunogens for generating anti-HIV1 bNAbs are also provided. Furthermore, methods for vaccination using suitable epitopes are provided.

Abstract: A process for the recovery of heat from the gas leaving a unit for the thermal hydrogenation of an oil feedstock, which process comprises quenching the gas with a quench liquid in a quenching zone in which all the internal surfaces thereof are irrigated by the quench liquid and passing the cooled gas and quench liquid to a heat recovery unit in which all the surfaces thereof in contact with gas are irrigated by the quench liquid.The process is particularly suitable for the recovery of heat from the gas leaving a fluidized bed hydrogenator.
