Mardin, is a city in the southeastern part of Turkey where people from different cultures and religions have been living together peacefully for centuries. The province hosted many valuable historical constructions representing different civilizations. Kasimiye Medresse, one of the most important educational centers of its times, has a sacred value for people in Mardin. The reason is that the s...

A Doença pulmonar obstrutiva crônica (DPOC) é caracterizada como uma inflamação do parênquima e das vias áreas, responsável por desencadear resposta pró-inflamatória que estimula a liberação dos leucócitos plaquetas. Uma características importantes dessa síndrome o aumento na contagem de polimorfonucleares (PMN), muitas vezes são liberados sua forma jovem apresentando alto nível mieloperoxidade...

Ultrasonic scalers are used in dentistry to remove calculus and other contaminants from teeth. One mechanism which may assist in the cleaning is cavitation generated in cooling water around the scaler. The vibratory motion of three designs of scaler tip in a water bath has been characterised by laser vibrometry, and compared with the spatial distribution of cavitation around the scaler tips obs...

Certain phenol derivatives, including p-iodophenol and p-phenylphenol, enhance light emission from the horseradish peroxidase-catalyzed oxidation of cyclic diacyl hydrazides such as luminol. The light emission decays slowly (glowing for several minutes) and its intensity may be greater than 1000-fold that of the unenhanced reaction. The enhanced system enables rapid, sensitive assay of peroxida...

A method for evaluating hydroxyl radical (·OH) scavenging activities using sequential injection analysis (SIA) with chemiluminescence (CL) detection was developed. In this system, CL was produced by the reaction of luminol with ·OH generated from the Fenton reaction. The scavenging activity was expressed as a diminution rate of the CL due to the scavenging of ·OH by a sample. The SIA system all...

Neste trabalho é descrito um procedimento automático em fluxo, para a determinação de L-alanina em meio de síntese. O método é baseado na oxidação do aminoácido pela L-aminoacido oxidise, seguida da detecção do H 2 O 2 formado, pela reação de quimiluminescência com o luminol. Para condicionamento da amostra, como diluição e ajuste do pH, foi utilizada a estratégia da reamostragem. Pelo procedim...

Upon mixing of oxovanadium(IV) acetylacetonate, this complex caused an increase in the chemiluminescence (CL) of luminol in a reverse micellar medium of cetyltrimethylammonium chloride in chloroform-cyclohexane (6:5 vlv)-water (buffered with NaOH-Na2C03, pH 12.5) even in the absence of an oxidizing reagent such as hydrogen peroxide. In this CL process, the reaction of Luminol with the oxovanadi...

Chemiluminescence can be used to identify defects in the oxidative metabolism of granulocytes. This procedure has recently been adopted for use with microliter quantities of whole blood, appropriate for prenatal or neonatal study. Although the contribution of myeloperoxidase to the chemiluminescence assay has been noted, the possible diagnostic confusion between chronic granulomatous disease of...
