Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic non-viral liver disease. Activation of macrophages and hepatic stellate cells is a critical step that promotes liver fibrosis. We aimed to explore the feasibility of interleukin-34 (IL-34), a key regulator of macrophages, as a fibrosis marker in patients with NAFLD. We enrolled 197 liver biopsy-proven NAFLD patients. We eval...
19S and 7S memory is analyzed in a system of cooperating antigenic determinants. Cooperation occurs in the induction of both 19S and 7S secondary antibodies, and for both responses carrier specificity can be entirely accounted for by presensitization of the animal to carrier determinants. The class distribution of secondary anti-hapten antibody depends on the dose of the hapten primary-carrier ...
An experimental procedure was developed to characterize the solubility of the soybean protein fractions close to the isoelectric point. The results show that the 7S fraction is precipitated in a much narrower range of pH values than the 11S fraction. Surprisingly, the addition of salt to the solutions leads to increased solubility of proteins, unlike the common "salting out" effect generally ex...
Changes in the reserve proteins of soybean seeds (Glycine max) were investigated by the techniques of disc electrophoresis and disc immunoelectrophoresis. Three different antisera were used in these studies, an anti-whole soybean extract serum 129, an anti-11S soybean protein monospecific serum 102, and an anti-7S soybean protein monospecific serum 132. At least 6 antigenically distinct compone...
Studies in man (1, 2), rabbit (3), and guinea pig (4) have shown that the 18S 71-macroglobu]ins (IgM) are catabolized much more rapidly than 7S 72-globulins (IgG). Thus, immunoglobulin classes may differ in their rates of turnover. Differences in the catabolic control of immunoglobulins are also discernable. The serum level of 7S 7-globulin (IgG) helps to determine the catabolic rate; the highe...

Corrections from the Breit interaction to basic properties of atomic Cs are determined in the framework of third-order relativistic many-body perturbation theory. The corrections to energies, hyperfine-structure constants, off-diagonal hyperfine 6S-7S amplitude, and electric-dipole matrix elements are tabulated. It is demonstrated that the Breit corrections to correlations are comparable to the...
The mechanism by which the moth Creatonotos transiens produces its male pheromone, (7R)-hydroxydanaidal, from heliotrine, an alkaloidal precursor of opposite (7S) stereochemistry, was investigated. Specifically deuteriated samples of heliotrine and epiheliotrine were prepared and fed to C. transiens larvae, and the steps in the biosynthetic process were monitored by gas chromatography/mass spec...
Lymph nodes and splenic tissue from patients with congenital agammaglobulinemia and dysgammaglobulinemia and from normal subjects were studied with the use of immunofluorescence and histochemical stains to determine the site of synthesis of the 19S gamma(1)-globulins. The two patients with dysgammaglobulinemia had high serum concentrations of the 19S gamma(1)-globulins and a marked deficit of t...
