Countercurrent-distribution studies on histones.
1. The possibilities of fractionating histones and histone fractions by means of countercurrent distribution between two phases formed by water and butan-2-ol, in the presence of various concentrations of trichloroacetic acid, have been examined. 2. Although the principal histone fractions differ considerably in their partition ratios, a satisfactory resolution of the principal histone fraction...
متن کاملCoordination and structural studies of crowned-porphyrins.
Simple chelating agents have been synthesized using a porphyrin and a covalently linked crown-ether. Depending on the relative spatial arrangement of both motifs, the resulting ligands, either a macrotricycle or bis-macrocycles, differ one from another by their flexibility or their aptitude to chelate bivalent or trivalent cations. The coordination chemistry as well as the structural study of t...
متن کاملCountercurrent Distribution Studies of E. Coli B Srna.
Since Holley'sl 2 initial application of countercurrent distribution (CCD) to the problem of the separation of the soluble ribonucleic acids (sRNA) of rat liver and yeast, considerable work has been done in this area by several investigators employing this technique.3-'0 Their primary interest has been to obtain purified specific sRNA's for structural studies. In the course of this work Doctor ...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Use of decellularized porcine liver for engineering humanized liver organ.
BACKGROUND New bioartificial liver devices are needed to supplement the limited supply of organ donors available for patients with end-stage liver disease. Here, we report the results of a pilot study aimed at developing a humanized porcine liver by transplanting second trimester human fetal hepatocytes (Hfh) co-cultured with fetal stellate cells (Hfsc) into the decellularized matrix of a porci...
