(6) Phospholipid methylation in human EGMs is distinctly different from that in rat EGMs (Hirata and Axelrod 1980) in that the human activity is not Mg++-dependent, and apparent methyltransferase I activity is located in the external membrane surface.
(7) The predicted non-Lorentzian line shapes and widths were found to be in good agreement with experimental results, indicating that the local orientational order (called "packing" by many workers) in the bilayers of small vesicles and in multilamellar membranes is substantially the same.
(8) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
(9) Using monoclonal antibodies directed against the plasma membrane of Madin-Darby canine kidney (MDCK) cells, we demonstrated previously that a glycoprotein with an Mr = 23,000 (gp23) had a non-polarized cell surface distribution and was observed on both the apical and basolateral membranes (Ojakian, G. K., Romain, R. E., and Herz, R. E. (1987) Am.
(10) The fraction of the viral dose which became cell associated was independent of the incubation temperature and increased with increasing target membrane concentration.
(11) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.
(12) The Cole-Moore effect, which was found here only under a specific set of conditions, thus may be a special case rather than the general property of the membrane.
(13) We have examined the insertion of bovine 17 alpha-hydroxylase (P45017 alpha) into the endoplasmic reticulum of COS 1 cells to evaluate the functional role of its hydrophobic amino-terminal sequence and membrane insertion.
(14) The transport of potassium ions through membranes of red blood cells was examined in in bitro experiments using a CMF of 4500 oersted.
(15) These membrane perturbation effects not observed with bleomycin-iron in the presence of a hydroxyl radical scavenger, dimethyl thiourea, or a chelating agent, desferrioxamine, were correlated with the ability of the complex to generate highly reactive oxygen species.
(16) Extensive studies during recent years have shown that the interaction between hormone and membrane-bound receptor can affect the receptor characteristics in at least two ways.
(17) Membranes of this material were filled with islets of Langerhans and implanted in the peritoneal cavity of rats.
(18) The penicillin-resistant Enterococcus hirae R40 has a typical profile of membrane-bound penicillin-binding proteins (PBPs) except that the 71 kDa PBP5 of low penicillin affinity represents about 50% of all the PBPs present.
(19) To investigate the mechanism of enhanced responsiveness of cholesterol-enriched human platelets, we compared stimulation by surface-membrane-receptor (thrombin) and post-receptor (AlF4-) G-protein-directed pathways.
(20) Moreover, in DCVC-treated cells the mitochondria could not be stained with rhodamine-123, indicating severe mitochondrial damage and loss of membrane potential.
Scurf
Definition:
(n.) Thin dry scales or scabs upon the body; especially, thin scales exfoliated from the cuticle, particularly of the scalp; dandruff.
(n.) Hence, the foul remains of anything adherent.
(n.) Anything like flakes or scales adhering to a surface.
(n.) Minute membranous scales on the surface of some leaves, as in the goosefoot.
Example Sentences:
(1) I had cooked, sometimes, with difficulty, yet woke one day to find I had somehow assembled a bizarre array of crockery on my floor, like a gnomes' tea party but with much scurf; I daily grew too fatigued to lift things and spent increasing hours abed.
(2) The relative contribution from loose scurf or from stratum corneum squames was not determined.
(3) Because diagnostic scales and scurf, or small scales, are easily lost in the process of collecting and preparing herbarium specimens of the new species, the potential for confusion among related species is increased.
(4) On the removal of the scurf covering the supposed entrance of the erysipelas, a larva of Dermatobia hominis, the human bot fly, was extracted from the head skin, and the inflammation completely disappeared within a short period of time.
(5) Minor scurfing and hair loss occurred on some calves with all compounds, but hair coats were normal 28 days after treatment.
(6) So now, when some drab functionary presents himself as speaking for the party, he is no more than scurf on a sea of money handed out by any opinionated casino magnate.
(7) Animal scurf extracts are nearly always contaminated with mites.
(8) A survey of vertical distribution showed no mite penetration deeper than inner stratum corneum where 57% of mite sections were seen; 30% were within outer stratum corneum or scurf; 13% were on the outer surface and less than 1% were detached.
(9) Within flocks, itchmite infested sheep or sheep with scurf had higher prevalences of fleece derangement than sheep on which no mites or no scurf were found.
(10) Among flocks, there were positive relations between the prevalence of fleece derangement and prevalence of itchmite or scurf and between itchmite count and mean scurf score.
(11) Horse or dog scurf collected in the summer months will be contaminated by pollens.
(12) Itchmite infested sheep had a higher prevalence of scurf than those with no detectable mite infestation.
