Incubation in vitro of the intestine of the hamster and guinea pig with 5 mM sodium cholate and with 2 mM sodium deoxycholate and sodium chenodeoxycholate resulted in significant morphological changes compared with control incubations. Generally, no major differences were observed between proximal and distal small intestine or between the species used. Only when guinea pig intestine was incubat...

Pancreatic cholesterol esterase (CEase) regulates dietary cholesterol absorption and is activated in the presence of trihydroxy bile salts while remaining inactive monohydroxy bile salts. CEase from rat pancreas has been purified by ammonium sulfate precipitation, hydroxylapatite chromatography, and gel filtration on Sephacryl S-200/S-300 columns connected in series, and its homogeneity and Mr ...

This paper describes a possible structure for the pamcrystalline form of the sodium salt of deoxyribonucleic acid. The structure consists of two DNA chains wound helically round a common axis, and held together by hydrogen bonds between specific pairs of bases. The assumptions made in deriving the structure are described, and co-ordinates are given for the principal atoms. The structure of the ...

  This study was carried out to investigate the rate of lipid oxidation in fresh rainbow trout (Onchorhynchus mykiss) and in the sticks treated by (2.5% w/v) sodium acetate (NaA), sodium citrate (NaC) and sodium lactate (NaL). The pH value, free fatty acid (FFA), thiobarbituric acid (TBA) and sensory evaluation (odor, flavor and color) were determined on 0, 3, 6, 9 and 12 days of storage. The r...

[1] During the Ice in Clouds Experiment‐Layer Clouds (ICE‐L), dry lakebed, or playa, salts from the Great Basin region of the United States were observed as cloud nuclei in orographic wave clouds over Wyoming. Using a counterflow virtual impactor in series with a single‐particle mass spectrometer, sodium‐potassium‐magnesium‐calcium‐chloride salts were identified as residues of cloud droplets. I...

Preconcentration of Cd and Pb at ultratrace level in waters following filtration through silver nanoparticles-cellulose composites used for thin-film microextraction was performed. The new procedure based on the formation pyrrolidine dithiocarbamate (APDC) derivatives, which showed a large affinity toward AgNPs. For this purpose, cellulose filters modified with AgNPs were prepared situ upon red...

Bile-salt hydrophobicity regulates biliary phospholipid secretion and subselection. The aim of this study was to determine whether bile salts can influence liver plasma membrane phospholipids and fluidity in relation to the ATP-dependent transporter. Rats were depleted of bile salts by overnight biliary diversion and then sodium taurocholate was infused intravenously at a constant rate (200 nmo...
