Cryptococcus neoformans is an important fungal pathogen that synthesizes melanin when grown in the presence of phenolic substrates. The ability of C. neoformans to produce melanin is associated with virulence, but the specific role of melanin in the

The radiobiological properties of a cyclotron-produced 43-MeV (p----Be) fast-neutron beam relative to gamma rays have been investigated using Chinese hamster V79 cells in culture. As expected, the relative biological effectiveness (RBE) of this neutr

In a kinematically complete experiment with 590 MeV protons, the reaction $^{6}\mathrm{Li}(p, pd)$ has been studied for recoil momenta up to 240 MeV/c. When the results are interpreted in terms of the plane wave impulse approximation, it is found tha

Analysis of soluble Ehrlich ascites proteins by the Sanger procedure revealed methionine, alanine, valine, and glycine as the major NH2-terminal amino acids. The average monomer weights of these proteins calculated from the yields of NH2-terminal ami

Encephalomyocarditis (EMC) viral RNA was isolated from purified virus grown in Ehrlich ascites tumor cells. The viral RNA was found to contain polyadenylic acid [poly(A)] regions that were very heterogeneous in length. Chromatography of the EMC viral

We investigated the effects of interferon treatment on virus yield, protein synthesis, and the 2-5A system in vaccinia virus-infected HeLa, L929, and CV1 cells. Under the culture conditions used, vaccinia virus replication was relatively insensitive

Differentially polyadenylated subpopulatons of encephalomyocarditis (EMC) viral RNA were isolated by affinity chromatography on oligodeoxythymidylic acid-cellulose. Translation of these RNA fractions in several in vitro protein-synthesizing systems,

2',5'-oligoadenylates can be assayed sensitively in cell extracts by use of an antiserum having maximum specificity for any compound containing the moiety -pA2'pA2'pA-. These compounds reached high concentrations (25-2000 nM) in monkey CV-1 cells aft

The T cell hybridoma FS7-20, produced by the fusion of normal B10.BR T cells to the AKR thymoma BW5147, was found when stimulated with concanavalin A (Con A) to produce the lymphokines: interleukin 2 (IL 2), interferon-gamma (IFN gamma), macrophage-a
