The plasma and kidney angiotensinases were compared in the rat . Effects of acid and alkali treatments and of enzyme inhibitors on the angiotensinase activities and the renin-angiotensionogen reaction were studied . Angiotensinase activity of the plasma was greatest near neutral pH at 37•Ž and was blocked almost completely by dialysis against disodium ethylenediaminetetraacetic acid (EDTA). The...

A ratiometric fluorescent nanoprobe based on terbium functionalized carbon dots (CDs) was designed to detect dipicolinic acid (DPA) as an anthrax biomarker with high selectivity and sensitivity. CDs were generated by one-step synthesis using an ethylenediaminetetraacetic acid precursor, and served as a scaffold for coordination with Tb(3+) and a fluorescence reference.

ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...

In this study, we synthesized a water-soluble poly(amic acid-co-imide) (PA-I) from ethylenediaminetetraacetic dianhydride (EDTA) and 2,2'-(ethylenedioxy)bis(ethylamine) that possesses comparable transfection efficiency to that of polyethylenimine (PEI), when prepared in combination with divalent calcium cations. The polycondensation of monomers afforded poly(amic acid) (PA) precursors, and subs...

Thermal inactivation of rabies and several other rhabdoviruses was studied using virus suspended in several different diluents. Rabies serogroup viruses were more stable than Kern Canyon or vesicular stomatitis viruses. Limited studies of two fish rhabdoviruses requiring low temperatures (less than 33 C) for replication indicated that they were not markedly more thermolabile than rabies virus. ...
