OBJECTIVE To assess the influence of final irrigation protocols with chlorhexidine in the coronal leakage of Enterococcus faecalis in filled root canals. MATERIAL AND METHODS Seventy single-root canals from extracted teeth were prepared using ProTaper instruments. The irrigation protocol accomplished an alternating irrigation with 5 mL of 2.5% sodium hypochlorite (NaOCI) and 17% EDTA between ...
BACKGROUND Insulin is recommended as a second-line treatment after diet and metformin fail to reach and/or maintain glycemic targets considered to minimize the risk for long-term diabetic complications. Hypoglycemia and the fear of developing hypoglyce-mia, however, remain substantial barriers to the initiation and optimal use of insulin. OBJECTIVE The aim of this study was to compare biphasi...
Migraine is a neurological disorder that correlates with an increased risk of cerebrovascular lesions. Genetic mutations of the MTHFR gene are correlated to migraine and to the increased risk of artery pathologies. Also, migraine patients show altered hematochemical parameters, linked to an impaired platelet aggregation mechanism. Hence, the vascular assessment of migraineurs is of primary impo...
BACKGROUND AND OBJECTIVES The properties of neuraminidase produced by P. aeruginosa strain PAO1 during growth in a defined medium (BHI) was examined and compared with some neuraminidase features of K. pneumoniae in this investigation. MATERIALS AND METHODS The enzyme was isolated from concentrated culture supernatants of P. aeruginosa which was used in a sensitive fluorometric assay by using ...
a series of hydroxysemicarbazone derivatives of substituted diaryl ketones and acetophenones were synthesized and their structures were confirmed by analytical and spectroscopic methods including elemental analysis, infrared and nuclear magnetic resonance spectroscopy. the derivatives were prepared by a condensation reaction between n-hydroxysemicarbazide and substituted diaryl ketones or aceto...
presently appearance of resistance to antifungal agents among aspergillus species is dramatically increasing. the objective of this study was to look at the in vitro activities of antifungal drugs against iranian clinical (from nail, bronchoalveolar lavage, paranasal sinus) isolated a. flavus strains. the susceptibility of 45 aflatoxigenic and non-aflatoxigenic aspergillus flavus strains were e...
In January 2006, the Clinical and Laboratory Standards Institute (CLSI) updated breakpoints for vancomycin susceptibility testing for Staphylococcus aureus such that an MIC greater than 2 mg/liter was considered to represent nonsusceptibility to vancomycin. Previously, an MIC of 4 mg/liter had been considered to represent susceptibility. Additionally, in 2009, the CLSI altered the guidelines fo...
Bioenergetics has become central to our understanding of pathological mechanisms, the development of new therapeutic strategies and as a biomarker for disease progression in neurodegeneration, diabetes, cancer and cardiovascular disease. A key concept is that the mitochondrion can act as the 'canary in the coal mine' by serving as an early warning of bioenergetic crisis in patient populations. ...
