A novel, mixed-valent copper(I)-copper(II) complex, {[bis(ethylene-diamine)copper(II)] bis[diiodocuprate(I)]} (1), has been prepared by electrochemical dissolution of a sacrificial copper anode in a solution of ethylenediamine (en), I2 and tetraethylammoniumperchlorate (TEAP) as supporting electrolyte in acetonitrile (AcN)and characterized by single-crystal X-ray structure determination. The cr...

Two synthetic pigment systems capable of enzymatically photoreducing NADP(+) are described. One system contains proflavine; the other, acridine. The complete system consists of ethylene diamine tetraacetic acid (EDTA), proflavine (or acridine), ferredoxin-NADP reductase (EC 1.6.99.4), and NADP(+). The two pigments initiate the photoreduction of NADP(+) in different portions of the electromagnet...

Siderophore type chelates were isolated from nutrient enriched seawater collected from coastal and near shore environments and detected using a novel high performance liquid chromatography – electrospray ionisation – mass spectrometric technique. Seawater was enriched with added glucose, ammonia and phosphate, and incubated for four days. Seven different siderophore type compounds were detected...

Ultraviolet and heat-curable polyurethane acrylate prepolymers were synthesized from 4,4’-diphenyl methane diisocyanate, polyethylene adipate diol, polyhexamethylene carbonate diol, polycaprolactone diol and 1,6hexamethylene diamine , acrylic acid. Effects of nature of the soft segments on the physical properties were investigated. It was found that the thermal stability increased from polycarb...

Multichannel electronic cell counters are now in widespread use in haematology laboratories. Platelet counts are given routinely by many instruments and low platelet counts generate much further investigation. A falsely low platelet count may expose the patient to unnecessary and expensive investigation and treatment, and we report two illustrative cases. The platelet counts were performed on b...

A novel, simple p-dimethyl amino benzyl ethylene diamine reagent has been synthesized under ordinary laboratory conditions and this reagent was successfully applied for the determination of Chromium (VI) in various environmental samples. This reagent yields a red colored complex with chromium metal solution in sodium acetate-acetic acid buffer of pH 7.0. Maximum absorption was obtained at 560 n...

barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. barite is not soluble in the regular solvents; such as, hydrochloric acid (hcl) and other acids. therefore, in this study, we focused on evaluating the dissolution of the industrial barite particles in different chelating agents. chelating agents; such as, dieth...

The mean corpuscular volume (MCV) of blood after storage for up to 24 days under various temperature conditions in ethylene diamine tetracetic acid, acid citrate dextrose, citrate phosphate dextrose, and Alsever's solution was measured using the Coulter S. Storage of blood overnight at 23 degrees centigrade increased the MCV, while there was no significant change after similar storage at 4 degr...

The interrelated effects of digitalis and various cations on cardiac rhythmicity are the subject of much recent interest. This paper presents additional data on this subject that carry important therapeutic implications. The chelating agent, disodium ethylene diamine tetra acetate (NaEDTA), has been used intravenously in 14 instances of supraventricular and ventricular arrhythmia. Digitalis had...
