Toxicity and stability of sodium cyanide in fresh water fish Nile tilapia
An experimental study was conducted to evaluate the effect of 0.129 NaCN mg/l for 28 days on the behavior of tilapia and the activities of adenosine triphosphatases enzyme (Na+/K+, Ca2+ and Mg2+-ATPase) within gill filaments, liver and muscles.

ADENOSINE TRIPHOSPHATASE LOCALIZATION IN AMPHIBIAN EPIDERMIS [PDF]
The localization of ATPase1 activity has been studied by light and electron microscopy in the epidermis of Rana pipiens, Rana catesbiana, and Bufo marinus. The reaction was carried out on skin (glutaraldehyde-fixed or fresh) sectioned with or without freezing. Best results were obtained with nonfrozen sections of fixed tissue.

ADENOSINE TRIPHOSPHATASE IN THE MITOTIC APPARATUS [PDF]
Methods.-Isolation of the mitotic apparatus: The principle of the new method has been described in several publications, and a detailed account of the procedure will appear shortly.5 Sea urchin eggs (Stronglycentrotus purpuratus) are the source of material, providing large quantities of cells in synchronous division.

LEAD-ADENOSINE TRIPHOSPHATE COMPLEXES IN ADENOSINE TRIPHOSPHATASE HISTOCHEMISTRY [PDF]
Chelation of lead by adenosine triphosphate (ATP) and its consequences for adenosine triphosphatase histochemistry were examined. The formation constant of lead-ATP chelates was found by two methods to be 4.6-4.7 x 104. The characteristics of enzyme inhibition by lead were consistent with the predicted effects of lead-ATP chelation.

Autophagic flux is required for the synthesis of triacylglycerols and ribosomal protein turnover in Chlamydomonas [PDF]
Autophagy is an intracellular catabolic process that allows cells to recycle unneeded or damaged material to maintain cellular homeostasis. This highly dynamic process is characterized by the formation of double-membrane vesicles called autophagosomes ...

Ultrastructural localization of adenosine triphosphatase activity in lymphocytes activated in vitro by phytohaemagglutinin [PDF]
The ultrastructural localization of Ca 2+, Mg2+ -activated ATPase was studied in phytohaemagglutinin activated lymphocytes and in normal unstimulated lymphocytes. Cells, fixed in paraformaldehyde-glutaraldehyde, were incubated in a medium containing 3 mM
