Ethylenediaminetetraacetic acid (EDTA) was developed by Franz Munz inGermanyduring the 1930s as an alternative to citric acid. About the same time, Frederick Bersworth synthesized EDTA in the United States using a different technique. He obtained aUSpatent for this technique in1945. EDTAwas approvedby the US Food and Drug Administration (FDA) as a food additive in 1947. Since the early 1950s, E...
Brucellosis is a zoonotic bacterial disease with worldwide distribution. A cross-sectional study was conducted to determine the serological prevalence of brucellosis in horses within Kano Metropolis. total 328 serum samples were collected for study. Modified Rose Bengal Plate Test (mRBPT) on all while Serum Agglutination EDTA (SAT-EDTA) mRBPT-positive samples. The metropolis found be 24.09 % (7...
Water-soluble polymers are attractive materials for pollutants removal thanks to their ability easily interact with soluble metal cations. In the present contribution, chemical modification of biocompatible and non-toxic poly(vinyl alcohol) (PVA) was achieved ethylene diamine tetraacetic acid (EDTA) groups, thus leading new water-soluble polymers, named PVA(EDTA). Modification carried out using...
Amidoximated algal/polyethyleneimine beads are successfully applied for the sorption of two rare earths elements (REEs, Ln(III)): La (light) and Dy (heavy). The properties characterized by FTIR SEM-EDX analyses. pH effect on metal is investigated with a double objective: optimizing recovery separation. In binary solutions, Dy(III) shows slightly higher affinity sorbent than La(III); without sig...
In ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia (PTCP), automated platelet counts are lower than actual counts because of EDTA-induced aggregation. Factors contributing to the incidence of EDTA-PTCP are unknown, and no study has assessed the prognosis of EDTA-PTCP patients. This retrospective study assessed characteristics in EDTA-PTCP patients and matched controls to...
O autor faz uma apreciação da técnica seguida no tratamento de dentes portadores condutos constritos e curvos. Inicia pela abertura câmara pulpar onde dá ênfase a perfeita retificação do 3° cervical dos condutos, apresentando instrumentação que realiza. Na fase seguinte é o químico-mecânico, preconiza para os amplos emprego soda clorada nos contritos EDTA (acido etilenodiamino tetra acético). C...
اندازه گیری و آنالیز ترکیباتی که به عنوان مواد افزودنی به داروها و مواد غذایی اضافه می شود از اهمیت ویژه ای برخوردار است. یکی از این ترکیبات edta است که به عنوان عامل شلات کننده به اغلب مواد دارویی و مواد غذایی اضافه می شود. در کار تحقیقاتی حاضر از دو روش مختلف برای اندازه گیری edta در سفتریاکسون سدیم و برخی دیگر از سفالوسپورین ها استفاده شد. در قسمت اول از روش میکرواستخراج مایع-مایع پخشی (dllm...
Plasma membrane and tonoplast vesicles were isolated from roots of both the glycophytic cultivated tomato, Lycopersicon esculentum (Mill, cv. Heinz 1350) and its halophytic wild relative, Lycopersicon cheesmanii (Hook, C.H. Mull, ecotype 1401) grown under control and saline conditions. MgATP-dependent proton transport was measured by determining the rate of quench of quinacrine fluorescence.. R...
In essential hypertension (ESS) whole body and vascular nitric oxide (NO) synthesis is generally thought to be reduced. We therefore investigated the systemic and renal responses to acute treatment with N(G)-monomethyl-l-arginine (L-NMMA), a competitive NOS-inhibitor, in 12 patients with ESS and 18 healthy controls (CON) in a randomized, placebo-controlled study. Main effect parameters were ren...
