The pine sawfly Diprion jingyuanensis Xiao and Zhang (Hymenoptera: Diprionidae) is a serious pest of Pinus tabulaeformis Carr. in the Shanxi, Gansu, Inner Mongolia provinces P. R. China. sex pheromone D. was shown to be propionate ester 3,7-dimethyl-2-tridecanol. Virgin females contained an approximate 1:3 blend precursors erythro-(2S,3S,7R/S 2R,3R,7R/S)-3,7-dimethyl-2-tridecanol threo-(2S,3R,7...

Cereal Chem. 63(6):493-496 Quantitative analyses of soybean globulins were made by densitometry Proteins extracted with both water and 0.5M sodium chloride contained in a sodium dodecyl sulfate (SDS)-polyacrylamide slab gel using lysozyme glycinin (36.5%), /3-conglycinin (27.8%), y-conglycinin (6.2%), Kunitz as an internal standard protein and Coomassie Brilliant Blue as a staining trypsin inhi...

Simian virus 40 (SV40) large tumor antigen (T antigen) exists in multiple molecular forms, some of which are separable by zone velocity sedimentation of soluble extracts from infected monkey cells. Three subclasses of this antigen from SV40-infected monkey cells have been separated and characterized: the 5S, 7S, and 14S forms. Newly synthesized T antigen occurs primarily in the 5S form. Chemica...

To assess the significance of serum basement membrane- and type III procollagen-related antigens in reflecting the degree of liver fibrosis, we measured radioimmunologically the concentrations of 7S collagen, laminin fragment P1, and the aminoterminal propeptide of type III procollagen (P-III-P) in serum from 48 patients with chronic viral liver disease: chronic persistent hepatitis (9), chroni...

The intracellular location of 7S and 42S RNP particles in Xenopus oocytes has been determined by immunohistochemistry. Using antibodies directed against the 48-mol-wt protein component of the 42S particle and against transcription factor IIIA, the protein moiety of the 7S particle, we show that these ribonucleoprotein particles are detectable only in the oocyte cytoplasm, being excluded from th...

In this study, the chitosan-induced coacervation of soy protein-isoflavone complexes in soymilk was investigated. Most of the soymilk proteins, including β-conglycinin (7S), glycinin (11S), and isoflavones, were found to coacervate into the soymilk pellet fraction (SPF) following the addition of 0.5% chitosan. The total protein in the soymilk supernatant fraction (SSF) decreased from 18.1 ± 0.3...

OBJECTIVES A low ratio of omega-6/omega-3 polyunsaturated fatty acids is associated with healthy bone properties. However, fatty diets can induce obesity. Our objective was to evaluate intra-abdominal adiposity, insulin, and bone growth in rats fed a high-fat diet containing low ratios of omega-6/omega-3 provided in canola oil. METHODS After weaning, rats were grouped and fed either a control...

Ribulose bisphosphate carboxylase consists of cytoplasmically synthesized "small" subunits and chloroplast-synthesized "large" subunits. Large subunits of ribulose bisphosphate carboxylase synthesized in vivo or in organello can be recovered from intact chloroplasts in the form of two different complexes with sedimentation coefficients of 7S and 29S. About one-third to one-half of the large sub...

We present lifetime measurements of the 7S 1/2 level and the 6p manifold of Rb. We use a time-correlated single-photon counting technique on a sample of 85 Rb atoms confined and cooled in a magneto-optical trap. The upper state of the 5P 1/2 repumping transition serves as the resonant intermediate level for two-photon excitation of the 7s level. A probe laser provides the second step of the exc...

Spinal muscular atrophy is a severe motor neuron disease caused by reduced levels of the ubiquitous Survival of MotoNeurons (SMN) protein. SMN is part of a complex that is essential for spliceosomal UsnRNP biogenesis. Signal recognition particle (SRP) is a ribonucleoprotein particle crucial for co-translational targeting of secretory and membrane proteins to the endoplasmic reticulum. SRP bioge...
