Many methods have been developed for the rapid and sensitive detection of Escherichia coli O157:H7 in milk and other foodstuffs. This study was designed to evaluate the application of RIDA®QUICK Verotoxin/O157 Combi kit, an immuno-chromatographic detection method, for the detection of this pathogen in raw milk. RIDA®QUICK kit showed appreciable results in detecting Escherichia coli O157:H7 in r...

According to Syed Naquib al-Attas and Mahayudin Yahaya, the teaching of Islam arrived in Malaysia during the end of 9 th century, though historical notes on the study and writing of Quranic exegesis or tafsir were not much found except after the 20 th century. Besides, reviewing the literature on the topic found that the writings do not describe the tafsir development in-depth as well factors d...

Background and objectives: Iron deficiency is one of the most common nutritional problems of human race. Helicobacter pylori (Hp) infection is the main known cause of gastritis, gastroduodenal ulcer and gastric cancer. The study was designed to evaluate the role of Hp infection in refractory iron deficiency anemia (rIDA) in adults, and to determine whether Hp eradication is an effective therape...

Regulatory inactivation of DnaA (RIDA) is one of the major regulatory mechanisms of prokaryotic replication licensing. In RIDA, the Hda-sliding clamp complex loaded onto DNA directly interacts with adenosine triphosphate (ATP)-bound DnaA and stimulates the hydrolysis of ATP to inactivate DnaA. A prediction is that the activity of Hda is tightly controlled to ensure that replication initiation o...

Initiation of DNA replication in Eschericia coli requires the ATP-bound form of the DnaA protein. The conversion of DnaA-ATP to DnaA-ADP is facilitated by a complex of DnaA, Hda (homologous to DnaA), and DNA-loaded beta-clamp proteins in a process termed RIDA (regulatory inactivation of DnaA). Hda-deficient cells initiate replication at each origin mainly once per cell cycle, and the rare reini...

BACKGROUND We compared the diagnostic performances of two newly introduced fully automated multiple allergen simultaneous tests (MAST) analyzers with two conventional MAST assays. METHODS The serum samples from a total of 53 and 104 patients were tested for food panels and inhalant panels, respectively, in four analyzers including AdvanSure AlloScreen (LG Life Science, Korea), AdvanSure Allos...

A ratiometric indicator-displacement assay (RIDA) array has been developed for the semi-quantitative colorimetric determination of chloride, bromide, and iodide anions. Determinations of these halide anions follow the displacement reaction using the chelate compound of (2-(3,5-dibromo-2-pyridylazo)-5-(diethylamino)phenol) (3,5-Br2-PADAP) and heavy metal salts as colorimetric reagent. Different ...
