Abstract This review concerns the speciation of protactinium in aqueous solution under its both oxidation states +IV and +V. Emphasis is placed on experimental data obtained at trace level but also macroscopic amount leading to determination thermodynamic structural data. Thus, complexation Pa(V) with mineral acids organic acids, mainly polyaminocarboxylic (iminodiacetic acid [IDA], nitrilotria...

The study was carried out on 30 clinically healthy dogs of various breeds. Haemoglobin concentration, haematocrit, platelet count and platelet haematocrit were significantly lower in citrate blood than in tripotassium ethylenediaminetetraacetic acid (EDTA-K3) blood. The study confirmed the limited usage of sodium citrate in haematology analysis, unless canine EDTA-dependent thrombocytopenia is ...

The dermatophyte Trichophyton schoenleinii elaborates an extracellular collagenase which is specific for native collagen and gelatin and is separable from an enzyme which is active against Azocoll. The fungal enzyme differs from the bacterial collagenases in its acid pH and small molecular weight. In addition, the fungal enzyme is irreversibly inhibited by ethylenediaminetetraacetic acid, where...

background: the varroa destructor varroasis is a very serious parasite of honeybee apis mellifera . the objective of this study was to evaluate the effectiveness of varroa treatment using organic acid (oxalic acid) in algeria identify­ing its side effects on bee colonies. methods : treatment was conducted in one apiary consisting 30 colonies kept in langstroth hives kind. oxalic acid dripped di...

Objective: To characterize based on a bibliographic review the irrigation techniques with greatest efficacy in removal of calcium hydroxide as intracanal medication. Materials and methods: Bibliographic carried out electronic databases PubMed, Scopus Web Science. 32 articles contained between years 2015 2020 were selected. Results: The most studied technique is ultrasonic irrigation, not achiev...

I recently read with a great interest the article by Sakalli and associates.1 They compared plasma levels of mean platelet volume (MPV) before and after renal transplant to investigate the possible role of determining renovascular thrombosis. In their study, no patients had any thrombotic events and/or renal allograft loss. Because of lack of a second group (composed of patients with renovascul...

Escherichia coli subjected to cold osmotic shock released 30 to 40% of their fatty acid esters and 42% of their cellular hexosamine. In contrast, Enterobacter, although they released 40% of fatty acid esters, release only 25% of hexosamine. Proteus released less than 15% of either fatty acid esters or hexosamine. These differences are taken to explain the differences among the Enterobacteriacea...

Sera from nine patients with cryptococcal infections and from four with rheumatoid arthritis and positive rheumatoid factor were examined for the presence of cryptococcal capsular antigen by the latex agglutination method. Ethylenediaminetetraacetic acid-heat treatment of the sera before testing possibly increased sensitivity as compared with the untreated sera, and the interfering rheumatoid f...

The vital role of ethylenediaminetetraacetic acid on the structure and the oxygen reduction reaction activity of the non-precious-metal-based pyrolyzed catalyst is reported and elaborated. The resultant catalyst can overtake the performance of commercial Pt/C catalyst in an alkaline medium.
