objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics. cone beam computed tomography (cbct)  has significantly enhanced image quality compared to digital radiography (dr) and greatly aids the diagnosis of vrfs but, metal artifacts has remained as a problem in vrf detection.  this study evaluated the effect of intra canal posts on the diagnostic accuracy of cbct and d...

Correction In the Methods section of our published article [1], the evolution of grain size and microstrain in the Mg and Cu is estimated using the single-line method of diffraction line-broadening analysis. However, a very important reference is omitted, and this method founder’s publication should be cited here [2]. Moreover, the experimental results contained in this paper were obtained by t...

Druggable Protein-protein Interaction Assessment System (Dr. PIAS) is a database of druggable protein-protein interactions (PPIs) predicted by our support vector machine (SVM)-based method. Since the first publication of this database, Dr. PIAS has been updated to version 2.0. PPI data have been increased considerably, from 71,500 to 83,324 entries. As the new positive instances in our method, ...

in recent decades, increasing advancement in biological sciences brings the need for reliable updated re-sources. scientific research journals facilitate accessibility to comprehensive resources and lay a ground for dis-seminating the latest findings of research projects to achieve constructive experiences and satisfy the scientific community. accordingly, avicenna research institute has publis...

Under policy 1, a person was screened using the chosen screening method until background or more advanced DR was detected. The person was then assessed in an outpatient clinic by an ophthalmologist using mydriatic seven-field photography. If retinopathy was confirmed screening was stopped, and if not, it resumed. Patients with background DR were seen at more frequent intervals in the ophthalmic...

this paper proposes a stochastic framework for demand response (dr) aggregator to procure dr from customers and sell it to purchasers in the wholesale electricity market. the aggregator assigns fixed dr contracts with customers based on three different load reduction strategies. in the presented problem the uncertainty of market price is considered and the risk of aggregator participation is ma...

objective(s):the utilization of molecular techniques in the epidemiology of tuberculosis have provided an opportunity for using effective markers to trace the transmission of the disease .the purpose of this study was to compare the genetic patterns of mycobacterium tuberculosis by three methods of rflp technique. materials and methods: in a cross-sectional and prospective study, 95 strains of ...

on the presence of cholera in its proper home, with additions by Dr. Bryden, Dr. Douglas Cunningham and Dr. Lewis, have been published for twelve years. These Indian reports stand pre-eminent in the literature of cholera, on account of the extensive observation on which they are based and the strict method on which they were conducted, and have the advantage that they do not regard the facts in...
