Seven polypeptides (a, b, c, 1, 2, 3a, and 3b) have been previously identified as tropomyosin isoforms in chicken embryo fibroblasts (CEF) (Lin, J. J.-C., Matsumura, F., and Yamashiro-Matsumura, S., 1984, J. Cell. Biol., 98:116-127). Spots a and c had identical mobility on two-dimensional gels with the slow-migrating and fast-migrating components, respectively, of chicken gizzard tropomyosin. H...

Insulin and insulin-related growth factor 1 (IGF-1) increase by 1.5-1.6-fold the rate of [3H]leucine incorporation into protein in primary monolayer cultures of chick-embryo fibroblasts (CEF); half-maximal hormone concentrations are 10 and 0.25 nM respectively. To investigate the mechanism of this effect, a rapid method is used to prepare a lysate from CEF which is active in protein synthesis. ...

We have measured high-resolution Ce 4d}4f resonant photoemission spectra of CeB 6 . In the on-resonance spectra, two peaks appear near the Fermi level (E F ). We have revealed that one corresponds to the 4f1 7@2 "nal state whereas the other one closer to E F is due to a mixture of the tail of the Kondo peak (! 8 "nal state) and its crystalline electric "eld (CEF) partner (! 7 "nal state). We al...

Infectious bursal disease (IBD), also known as Gumboro disease, is a globally well-known disease with a significant socio-economic effect. For control of IBD, several commercial egg- and cell-based vaccines are prepared. The cell-based IBD vaccines are significantly cost-effective; however, it is essential to confirm their safety and efficacy. The main cell line used to product the cell-based I...

CeRh$_6$Ge$_4$ is an unusual example of a stoichiometric heavy fermion ferromagnet, which can be cleanly tuned by hydrostatic pressure to quantum critical point. In order understand the origin this anomalous behavior, we have characterized magnetic ordering and crystalline electric field (CEF) scheme system. While Bragg peaks are not resolved in neutron powder diffraction, coherent oscillations...

In higher plants, moderate photoinhibition of photosystem II (PSII) leads to a stimulation of cyclic electron flow (CEF) at low light, which is accompanied by an increase in the P700 oxidation ratio. However, the specific role of CEF stimulation at low light is not well known. Furthermore, the mechanism underlying this increase in P700 oxidation ratio at low light is unclear. To address these q...

Elevated reactive oxygen species (ROS) levels have been observed in mammals during aging, implying an important role of ROS in the aging process. Most bird species are known to live longer and to contain lower ROS levels than mammals of the same body weight. The influence of ROS on the aging process of birds has been investigated using pigeon embryonic fibroblasts (PEF) and chicken embryonic fi...

In addition to the linear electron flow, a cyclic electron flow (CEF) around photosystem I occurs in chloroplasts. In CEF, electrons flow back from the donor site of photosystem I to the plastoquinone pool via two main routes: one that involves the Proton Gradient Regulation5 (PGR5)/PGRL1 complex (PGR) and one that is dependent of the NADH dehydrogenase-like complex. While the importance of CEF...

In order to exploit the potential benefits of antimicrobial combination therapy, we need a better understanding of the circumstances under which pharmacodynamic interactions expected. In this study, Pharmacodynamic interactions between silver nanoparticle (SNP) and topical antibiotics such as Cefazolin (CEF), Mupirocin (MUP), Gentamycin (GEN), Neomycin (NEO), Tetracycline (TET), Vancomycin (VAN...

Objective: To evaluate frame constructs, surgical technique, postoperative care, complications, treatment duration, and outcome of circular external fixation (CEF) for treatment of 30 antebrachial and crural angular deformities in dogs. Study Design: Retrospective study. Sample Population: Twenty-seven dogs with limb deformities. Methods: Medical records of dogs that underwent surgery with CEF ...
