background and aims. the aim of this study was to evaluate the antibacterial activity of one-step self-etch adhesives on enterococcus faecalis on days 1, 7 and 14 with the use of modified direct contact test. materials and methods. the modified direct contact test was used to evaluate the antibacterial effect of adper easy one, bond force, clearfil s3 bond, futurabond m, g-bond, ibond and optib...

BACKGROUND The influence of diet on intestinal microflora has been investigated mainly using conventional microbiological approaches. Although these studies have advanced knowledge on human intestinal microflora, it is imperative that new methods are applied to facilitate scientific progress. Culture-independent molecular fingerprinting method of Polymerase Chain Reaction and Denaturing Gradien...

in a cross section of the patients scheduled for various operations, the plausability of lidocaine as an induction agent is studied and described. the results were dismaying suggesting, henceforth, that as an induction agent, lidocaine altogether fails to accomplish the assignment assigned to this drug.

Sample preparation is one of the most time-consuming steps in diagnostic assays, particularly those involving biological samples. In this paper we report results finite-difference time-domain (FDTD) simulations and thermographic imaging experiments carried out with intent designing a microplate for rapid, high-throughput sample to aid assays. This work based on devices known as microwave lysing...

objective: etching of enamel and dentin is an important step in restoration of teeth with composite resin ensuring the retention of restoration and decreasing microleakage. this in vitro study sought to compare the effects of kimiya and etch-rite acid etchants on the microleakage of composite restorations.   methods: this experimental study was conducted on 30 sound human molar teeth. class v c...

Legionella pneumophila, the etiologic agent of Legionnaires' disease, is phagocytized in an unusual way and multiplies in human mononuclear phagocytes in a novel phagosome. As a first step toward understanding these L. pneumophila-phagocyte interactions, we have studied the envelope of L. pneumophila Philadelphia 1 strain. We isolated cell envelopes by treating whole bacterial cells with lysozy...
