Abstract
Persistence and extinction attributes of a discrete population model are explored on both a finite and an infinite time horizon. For a first-order autonomous nonlinear difference equation, a classification is found of when, for each positive integer N, trajectories go to extinction at time N. The dynamic complexity that is known to permeate difference-equation models is also present in the survival analyses developed here. Also found is an interesting decomposition of the continuum of initial population sizes into intervals where populations are persistent at time N and intervals leading to extinction at time n less than or equal to N.

Abstract
We have shown that hydrocortisone in physiological concentrations can inhibit the production of leukocyte migration inhibition factor (LMIF), but does not diminish the action of this lymphokine. Other agents tested failed to influence LMIF production. Inhibition of LMIF production by corticosteroids was influenced by the nature of the stimulus used for the production as an effect could be seen with PHA or Con A, but not Staphylococcal enterotoxin A (SEA). Production of LMIF was promptly restored after removal of the steroids. Furthermore, addition of a calcium ionophore to PHA restored the production of LMIF even in the presence of corticosteroids. In contrast, addition of exogenous IL-2 did not correct the defect in lymphokine secretion. We believe that inhibition of the production of LMIF by steroid may lead to defective granulocytic function and thus, predispose to infection.

Abstract
A new isolate of reticuloendotheliosis virus (REV) from ducks, RU-1, was used to experimentally infect white pekin ducks. Embryonal or neonatal infection usually resulted in persistent viremias, no REV antibody development, and inability to mount antibody responses against bovine serum albumin (BSA) or sheep red blood cells (SRBC). In contrast, infection at 21 days of age resulted in transient viremias, which terminated coincident with REV antibody development. These ducks remained persistently infected, however, based on virus isolations from peripheral blood lymphocytes. Ducks infected at that age were immunologically competent against BSA and SRBC unless they had been embryonally bursectomized, in which case they behaved virologically and immunologically like those infected at an early age. Bursectomy by itself did not prevent responses against the antigens. Total mortality during 4- or 6-month experimental periods ranged from 80 to 100% in REV-infected groups, regardless of age at infection, route of exposure, or whether the ducks were intact or bursectomized. Most deaths were from non-neoplastic conditions (stunting, bacterial infections), but 17 of 69 (25%) infected ducks developed a variety of neoplasms, including lymphosarcomas, histiocytic sarcomas, and spindle-cell sarcomas.

Abstract
We have examined the reduction of cyanide by using the purified component proteins of nitrogenase (Av1 and Av2). The previously reported self-inhibition phenomenon was found to be an artifact. One of the two species present in cyanide solutions, CN-, was shown to be a potent reversible inhibitor (Ki = 27 microM) of total electron flow, apparently uncoupling MgATP hydrolysis and electron transfer. There appears to be no differential effect of CN- on the specific activities of Av1 and Av2 nor is there any apparent irreversible physical damage to Av2. CN- inhibition is completely reversed by low levels of CO, implying a common binding site. Azide partially relieves the inhibitory effect, but other substrates and inhibitors (N2, C2H2, N2O, H2) have no effect. The other species present in cyanide solutions, HCN, was shown to be the substrate (Km = 4.5 mM at Av2/Av1 = 8), and extrapolation of the data indicates that at high enough HCN concentration H2 evolution can be eliminated. The products are methane plus ammonia (six electrons), and methylamine (four electrons). There is an excess (relative to methane) of ammonia formed, which, according to electron balance studies, may arise from a two-electron intermediate. Both nitrous oxide and acetylene (but not N2) influence the distribution of cyanide reduction products, implying simultaneous binding. HCN appears to bind to and be reduced at an enzyme state more oxidized than the one responsible for either H2 evolution or N2 reduction.

Abstract
Continued studies of the macrophage-derived mediator of SAA synthesis (SAA Stimulating Factor) confirm our previous observations that SAASF copurified with leukocytic pyrogen (LP) and lymphocyte activating factor (LAF). Moreover, new data demonstrate three separate isoelectric points for human LP-LAF-SAASF each of which possess the three biological activities. During the purification of 15,000 MW LP from crude stimulated mononuclear cell supernatants, only those fractions with pyrogenic activity in rabbits caused augmented stimulation of lymphocytes (LAF) and induced SAA synthesis in mice. Purified human LP stimulated isolated mouse hepatocytes in vitro to synthesize SAA in a dose-responsive manner. Colchicine treatment of hepatocytes led to decreased secretion of SAA into the medium and to an intracellular accumulation of SAA. Messenger RNA was isolated from the livers of endotoxin-stimulated mice and translated in a wheat-germ cell-free system. A major product was identified at 13-14,000 MW. Immunoprecipitation with anti-mouse AA identified several bands on autoradiography of polyacrylamide gels. These larger SAA precursors may account for the previously noted heterogeneity of human SAA, comprising at least 6 SAA isomers, of similar molecular weight but different solubility and electrophoretic charge characteristics. Two monoclonal antibodies (IgM-K and IgG1-K) have been prepared using standard cell hybridization techniques. They are directed at the variable COOH terminal region of SAA since they detect differences between the 6 human SAAs but do not react with human, monkey, dog or mouse AA proteins, human AP, C-reactive protein, IgG nor albumin. These antibodies will be useful in examining the origin, structure and function of SAA.
