S tudents often approach the familiar stories of the Bible wondering what more they can learn from texts they have been reading since childhood.As teachers, we face the challenge of getting students to focus on the text itself, without being overly influenced by the preconceptions and interpretations that have become attached to these stories through centuries of retelling and commentary. One d...

OBJECTIVE To evaluate the Bedtime Pass Program (BPP), an extinction-based procedure for treating bedtime resistance in typically developing children. METHODS A randomized, controlled trial in which nineteen 3- to 6-year-old children demonstrating bedtime resistance were randomly assigned to a Bedtime Pass or Monitoring Control group. The experimental condition involved parent monitoring plus ...

Aim: To evaluate the resistance of union between a glass fiber post and radicular dentine after cleaning root with 17% EDTA filling different endodontic cements. Methods: Forty uniradicular bovine incisors were removed to obtain lengths 18 mm. Endodontic treatment was performed on all roots using cements (zinc oxide eugenol-based, OZE; cement based epoxy resin, AH) solutions (saline, SA or EDTA...

Purified human serum butyrylcholinesterase after treatment with either of the metal chelators EDTA or NaCN was able to bind to a Zn(2+)-chelate-Sepharose affinity column and was eluted from the column by EDTA or imidazole. Prior EDTA treatment of the enzyme was essential for binding to this affinity column. The enzyme could be labelled with (65)Zn(2+) after EDTA treatment of the enzyme. Diethyl...

A convenient HPLC method for the quantitative determination of EDTA in foods was developed. EDTA in food samples was easily extracted with water by ultrasonication. After converting to Fe(III) complex in the presence of Fe(III) ions, EDTA was separated on a reversed-phase C30 column and detected with ultraviolet detection (260 nm). Citrate and malate, which are present in many foods, also forme...

The presence of endotoxin inside the root canal has been associated with periapical inflammation, bone resorption and symptomatic conditions.Objectives To determine, in vitro, the effect of QMix® and other three root canal irrigants in reducing the endotoxin content in root canals.Material and Methods Root canals of single-rooted teeth were prepared. Samples were detoxified with Co-60 irradiati...

In cancer patients with long-term central venous catheters (CVC), removal and reinsertion of a new CVC at a different site might be difficult because of the unavailability of accessible vascular sites. In vitro and animal studies showed that a minocycline-EDTA-ethanol (M-EDTA-EtOH) lock solution may eradicate microbial organisms in biofilms, hence enabling the treatment of central line-associat...

The current maximum acceptable daily intake (ADI) of ethylenediaminetetraacetic acid (EDTA) of 1.9 mg day(-1) per kilogram bodyweight (mg day(-1)  kgbw(-1) ) limits the daily intake of iron as iron EDTA [ferric sodium EDTA; sodium iron(III) EDTA] to approximately 2-2.5 mg day(-1) for children 6-24 months of age. This limit was defined by the Joint FAO/WHO Expert Committee on Food Additives (JEC...
