2014 Mössbauer measurements are reported on 169Tm3+ in TmPO4 and on 170Yb3+ in TmXO4 and in YbXO4 (X = P, V). The measured hyperfine parameters are used to provide information concerning the electronic properties of the rare earth ions. A set of crystalline electric field (CEF) parameters is obtained for Tm3+ in TmPO4 and previously proposed CEF parameters for Tm3+ in TmVO4 are discussed. The m...

36 Cyclic electron flux (CEF) around Photosystem I (PS I) is essential for efficient photosynthesis 37 and aids photoprotection, especially in stressful conditions, but the difficulty in quantifying CEF 38 is non-trivial. The total electron flux through PS I (ETR1) and the linear electron flux (LEFO2) 39 through both photosystems in spinach leaf discs were estimated from the photochemical yield...

Cyclic electron flow around photosystem I (CEF) is critical for balancing the photosynthetic energy budget of the chloroplast, by generating ATP without net production of NADPH. We demonstrate that the chloroplast NADPH dehydrogenase complex (NDH), a homolog to respiratory Complex I, pumps approximately two protons from the chloroplast stroma to the lumen per electron transferred from ferredoxi...

in order to adapt lasota strain of newcastle disease virus (ndv) on chick embryo fibroblast (cef) cells, 0.1 ml from lasota vaccine produced in razi vaccine and serum research institute inoculated to the cef cells and was passaged five times in the cef grown in eagle’s minimum essential medium (mem). first to third passages were blind but in fourth passage cytopathic effect of virus was observe...

Reverse transcriptase (RT) activity has been detected recently in all chicken cell-derived measles and mumps vaccines. A study of a vaccine manufactured in Europe indicated that the RT is associated with particles containing endogenous avian retrovirus (EAV-0) RNA and originates from the chicken embryonic fibroblasts (CEF) used as a substrate for propagation of the vaccine. We investigated the ...

Clusterin is a major protein in bull reproductive tract secretions and sperm membrane extract. A polyclonal antibody was produced against clusterin from bull cauda epididymal fluid (CEF) and used for the localization of the protein on bull spermatozoa. Immunoblotting of unreduced bovine samples showed that the anticlusterin antibody reacted with a protein of approximately 94- to 100-kd in rete ...

In view of the potential menace of a terrorism attack with smallpox virus, an intensive search of chemotherapeutic agents active against orthopoxviruses is underway. We comparatively studied the antiviral activity of cidofovir (CDV) and idoxuridine (IUdR) against two vaccinia virus (VV) strains, Bratislava and RIIPD, in cell cultures of chick embryo fibroblasts (CEF). The investigations were ca...

PURPOSE A number of prospective studies have shown that adjuvant CEF significantly improves disease-free and overall survival as compared to CMF in breast cancer patients. Our aim was to determine whether the benefit of epirubicin versus methotrexate differs according to TIMP-1 tumour cell immunoreactivity. EXPERIMENTAL DESIGN Tissue micro arrays from 647 patients randomly assigned to CMF or ...

Purpose: Recent studies suggest that intrinsic breast cancer subtypesmay differ in their responsiveness to specific chemotherapy regimens. We examined this hypothesis on NCIC.CTG MA.5, a clinical trial randomizing premenopausal women with node-positive breast cancer to adjuvant CMF (cyclophosphamide-methotrexate-fluorouracil) versus CEF (cyclophosphamide-epirubicin-fluorouracil) chemotherapy. E...

On the basis of point charge model, we formulate crystalline electronic field (CEF) Hamiltonian HCEF in rare-earth based quasicrystal (QC) and approximant crystal (AC) with ligand ions located at pseudo 5-fold configurations by using operator equivalent method. By setting total angular momentum J = 7/2, CEF quantum critical QC Au51Al34Yb15 1/1 AC Au51Al35Yb14 is analyzed consideration for effec...
