INTRODUCTION The aim of this in vitro study was to evaluate the antimicrobial activity of four intracanal medicaments on Enterococcus Faecalis (E. Faecalis). METHODS AND MATERIALS Fifty extracted single-rooted human teeth were prepared with standard method. After contaminating the canals with E. Faecalis, the samples were divided into one control and four experimental groups (n=10). The teeth...

The Arabidopsis thaliana plasma membrane proton ATPase genes, AHA1 and AHA2, are the two most highly expressed isoforms of an 11 gene family and are collectively essential for embryo development. We report the translational fusion of a tandem affinity-purification tag to the 5' end of the AHA1 open reading frame in a genomic clone. Stable expression of TAP-tagged AHA1 in Arabidopsis rescues the...

We used an artificial neural network (ANN) computer model to study peptide binding to the human transporter associated with antigen processing (TAP). After validation, an ANN model of TAP-peptide binding was used to mine a database of HLA-binding peptides to elucidate patterns of TAP binding. The affinity of HLA-binding peptides for TAP was found to differ according to the HLA supertype concern...

rhizomania disease is one of the most important threats to worldwide and iran sugar beet cultivation. many studies have been done to understanding the physiological effects of the disease on sugar beet, but in iran conditions has not been done any study for this purpose. this experiment was conducted with four sugar beet cultivars named as brigita, zarghan, jolge and rasoul in 2010 and natural ...

PURPOSE The transversus abdominis plane (TAP) block is a technique increasingly used for analgesia after surgery on the anterior abdominal wall. We undertook this study to determine the feasibility and analgesic efficacy of ultrasound-guided TAP blocks in morbidly obese patients. We describe the dermatomal spread of local anesthetic in TAP blocks administered, and test the hypothesis that TAP b...

Early-successional vegetation is often a major factor that limits recovery of tropical forest in abandoned pastures by outcompeting seedlings of forest trees. The goal of this study was to compare the effects of aboveand below-ground competition of pasture grasses and shrubs on the growth of tree seedlings in abandoned tropical pasture in Costa Rica. Seedlings of Calophyllum brasiliense were pl...

Endodontic posttreatment pain remains to be a significant problem facing the dental profession. Antibacterial intracanal dressing has been advocated to eliminate remaining bacteria after chemomechanical preparation.1 Various intracanal medicaments are advocated to eliminate bacteria and prevent multiplication of bacteria between the appointments. Calcium hydroxide (CH) has been the most commonl...

‘‘Power corrupts.’’ – I. Amin Often the people most qualified to perform certain system administration tasks are not necessarily qualified to have root access in general. This paper will discuss the rationale and methods for having non-root accounts do some types of systems administration. We will discuss two subsystems which we are currently administering without root and apply that experience...

Root canal infection in primary teeth is polymicrobial nature. Most resistant micro-organisms, such as E.faecalis survive chronic of the root at periapical area and are difficult to remove by various irrigants. C.albicans has been found infections canals due its ability invade dentinal tubules. The multiple bacteria strains which cause en...
