HIGH-YIELD PREPARATION OF ISOLATED RAT LIVER PARENCHYMAL CELLS: A Biochemical and Fine Structural Study
M. N. Berry,Daniel S. Friend +1 more
TL;DR: Cytoplasmic vacuolization in a small percentage of cells and potassium loss are the only indications of cell injury detected, and the isolated cells are comparable to normal hepatic parenchymal cells in situ in appearance and function.

Automated simultaneous determination of ammonia and total amino acids in ruminal fluid and in vitro media
G.A. Broderick,J.H. Kang +1 more
TL;DR: Catalyzed phenol-hypochlorite and ninhydrin colorimetric procedures were adapted to the Technicon AutoAnalyzer for simultaneous determination of ammonia and total amino acids in ruminal fluid or ruminal in vitro media and indicated high degrees of accuracy and precision for both ammonia and amino acid analyses.

Hydrogenation and cleavage of dinitrogen to ammonia with a zirconium complex
TL;DR: This work extends work on zirconium complexes containing cyclopentadienyl ligands and shows that adjustment of the ligands allows direct observation of N–H bond formation from N2 and H2.
