introduction: an important consideration in endodontic treatment is the elimination of microorganisms, including fungi, from the complex three- dimensional root canal system. candida albicans (ca) has a major role in endodontic treatment failure as the most important fungus isolated from the root canal system. the present study was carried out to evaluate the presence of ca in the teeth requiri...

A novel, simple and efficient cofactor recycling method for enantioselective bioreduction has been developed by the use of permeabilized cells of a reductase-containing microorganism and a glucose dehydrogenase-containing microorganism

Objectives: The aim of this study was to evaluate the antimicrobial efficacy Potassium Titanium Phosphate (KTP) laser-activated irrigation solutions on intraradicular Enterococcus faecalis biofilms in invitro conditions by using a scanning electron microscope. 
 Materials and Methods: 120 single-root, single canal permanent mandibular premolar human teeth were used. Sterilization disinfect...

The Brownian dynamics of a single microorganism coupled by chemotaxis to a diffusing concentration field that is secreted by the microorganism itself is studied by computer simulations in spatial dimensions d=1,2,3 . Both cases of a chemoattractant and a chemorepellent are discussed. For a chemoattractant, we find a transient dynamical arrest until the microorganism diffuses for long times. For...

A total number of 1735 clinically suspected as UTI cases were sent for urine culture sensi vity. Total culture posi ve were 239 (13.8%). The majority of isolates were from female pa ents comprising 180 (75%). The most common pathogenic microorganism isolated was E.coli (79.1%). Second most common organism was Klebsiella (11.7%) followed by Citrobacter (3.34%) and Proteus (2.92%). The isolated m...
