Studies were performed to determine the mechanism by which stearic acid (18:0) selectively inhibits T-dependent immune responses in vitro. Incubation of mitogen-activated B and T cells with 18:0 resulted in dissimilar patterns of incorporation of the saturated fatty acid into their membranes. High-performance liquid chromatography (HPLC) analyses of T cells showed an accumulation of disaturated...

We establish universality and ultra-homogeneity of ( U , u GH ) the collection all compact ultrametric spaces endowed with so-called Gromov-Hausdorff . This result also gives rise to a novel construction R-Urysohn universal space for each countable subset R ⊂ ≥ 0 containing 0.

A theoretical study of compounds containing Be in the +1 or 0 oxidation state has been carried out. The molecules considered containing Be in the +1 oxidation state are analogues of the important Mg(I)-Mg(I) dimer supported by the β-diketiminate ligand. The molecules in the 0 oxidation state are NHC supported compounds analogous to "molecular allotropes" which has recently become a topic of imp...

Similar populations of Pseudomonas fragi were grown at 25 C for 20 hr or at 7 C for 7 days in milk containing 0, 10, and 20% fat; they were then heated at 48, 50, and 52 C in milk containing 0, 10, and 20% fat. After inoculation, the heating medium contained 2.1 x 10(6) to 6.9 x 10(6) organisms per milliliter. The P. fragi cells grown in skim milk had greater thermal resistance (D(52) = 3.0 to ...

Given a topologically free action of countable group G on compact metric space X, there is canonical correspondence between continuous 1-cocycles for this and diagonal 1-parameter groups automorphisms the reduced crossed product C $$^*$$ -algebra. The KMS spectrum defined as set inverse temperatures which exists state. We prove that possible spectra depend heavily nature acting G. For subexpone...
