Twitter can serve as a powerful communication modality to both "push" and "pull" public health data; each user is a potential public health sensor and actor. However, in 2012, only 8% of local health departments had Twitter accounts. We outline how Twitter works, describe how to access public tweets for public health surveillance purposes, review the(More)
The conformation of an Asn-linked glycopeptide in H2O was studied by two-dimensional 1H NMR. Nonexchangeable proton and exchangeable amide (NH) proton resonances were assigned for the hen ovomucoid glycopeptide 1, Ser-Ile-Glu-Phe-Gly-Thr-Asn Ile-Ser-Lys, with pentasaccharide Man alpha 1-3 (Man alpha 1-6)Man beta 1-4GlcNAc beta 1-4GlcNAc beta 1-NH attached(More)
We report transient expression of a full-length cDNA encoding the Ca2+ release channel of rabbit skeletal muscle sarcoplasmic reticulum (ryanodine receptor) in HEK-293 cells. The single-channel properties of the 3-[(3-cholamidopropyl)dimethylammonio]-1-propane sulfonate-solubilized and sucrose gradient-purified recombinant Ca2+ release channels were(More)
Myelin vesicles have been obtained from isolated rat brain myelin and shown by electron microscopy to consist of single bilayer membranes. The yield of the preparation is approximately 25% of the myelin proteins. The vesicles show a typical myelin protein pattern on sodium dodecyl sulfate-polyacrylamide gel electrophoresis and contain activity for the(More)
A glycosylation variant of human tissue-type plasminogen activator (tPA) designated longer-acting tissue-type plasminogen activator (LAtPA) was extensively purified from the milk of a transgenic goat by a combination of acid fractionation, hydrophobic interaction chromatography and immunoaffinity chromatography. This scheme provided greater than 8,000-fold(More)
1. Myelin proteolipid proteins (PLPs) from five animal species were compared immunochemically. In direct electroblot, ELISA or immunodot analyses, anti-bovine PLP antiserum reacted similarly with bovine, guinea-pig, human, mouse and rat myelin PLP. In contrast, antiserum to bovine BPS4, a fragment obtained by chemical cleavage of bovine PLP, reacted(More)
