The efficiency of receptor-mediated entry of pseudotyped virus carrying the surface protein (SU) of clone A8, a neuropathogenic variant of Friend murine leukemia virus (FrMLV), to rat glial cell line F10 was 1 order of magnitude greater than that of pseudotyped virus carrying SU of nonneuropathogenic FrMLV clone 57. Introduction of the gene coding for ecotropic MLV receptor on F10 cells (F10-ec...
The immunogenicity of a chimeric T/B cell peptide corresponding to antigenically characterized epitopes of the Chlamydia trachomatis major outer membrane protein (MOMP) was studied in mice to further define its potential use in the development of a subunit vaccine in preventing blinding trachoma in humans. The chimeric peptide, designated A8-VDI, corresponds to a conserved MOMP T helper (Th) ce...
The Mycotrim Triphasic flask system (Irvine Scientific, Irvine, Calif.) was compared with a system composed of Mycotrim GU broth (Irvine Scientific) and A7 or A8 agar (Remel, Lenexa, Kans.) for the ability to detect Ureaplasma urealyticum and Mycoplasma hominis from 129 genital specimens. Of the 64 specimens positive for U. urealyticum, 25, 98, and 100% were detected on Mycotrim Triphasic agar ...
Amphipols are amphipathic polymers designed to replace or supplement detergents in membrane protein solution studies. Previous work has suggested both advantages and disadvantages to the use of a polyacrylate-based amphipol, A8-35, for studying the sarcoplasmic reticulum Ca2+-ATPase (SERCA1a). We investigated this issue further using a set of four amphipols with different chemical structures. P...
We present high-level ab initio calculations for the global adiabatic potential energy surfaces of the ground state (X̃ A8) and several excited states ~Ã A8, B̃ A9, C̃ A8, D̃ A8, and Ẽ A9! of LiFH, including the valleys leading to Li1HF and LiF1H. The ab initio calculations were carried out using the multireference singles and doubles configuration interaction method with 99 reference configuration...
Friend murine leukemia virus (F-MuLV) clone A8, previously shown to cause spongiform degeneration in rat brain, induced leukemia within 10 weeks after infection when inoculated into newborn rats. The chimeric virus Rec2, which contains the pol and env genes of 57 virus on the background of A8 and does not cause spongiform degeneration in the central nervous system (CNS), induced leukemic cell i...
Trifluperidol (TFP), at a concentration of 100 ,M, inhibited the 24-h growth of Saccharomyces cerevisiae by about 30%. Effects on lipid metabolism were investigated by monitoring the incorporation of [1-14C]sodium acetate into various lipid fractions after 4 and 24 h ofgrowth in the presence of several concentrations of TFP. Although little effect was noted on the amount of free sterols, 24-h i...
The mesotelencephalic dopamine system is genetically variable and affects motor behavior, motivation, and learning. Here we examine the genetic variation of mesencephalic DA neuron number in a quasi-congenic RQI mouse strain and its background partner and in a recombinant inbred strain with different levels of mesencephalic tyrosine hydroxylase activity (TH/MES). We used B6.Cb4i5-alpha6/Vad, C5...
BACKGROUND Exosomes, via heat shock protein 70 (HSP70) expressed in their membrane, are able to interact with the toll-like receptor 2 (TLR2) on myeloid-derived suppressive cells (MDSCs), thereby activating them. METHODS We analyzed exosomes from mouse (C57Bl/6) and breast, lung, and ovarian cancer patient samples and cultured cancer cells with different approaches, including nanoparticle tra...
Using diagnostic criteria which are currently accepted as most reliable we have found that 19% (9/47) of patients with dermatitis herpetiformis (DH) have no evidence of coeliac disease. The incidence of HL-A8 in the DH patients was 78%, which is considerably greater than that in healthy controls and no different from that reported in coeliac disease. Furthermore, the incidence of HL-A8 was just...
