UNLABELLED The constant-volume urinary bladder model in the standard MIRD Pamphlet No. 5 (Revised) phantom has recognized limitations. Various investigators have developed detailed models incorporating more physiologically realistic features, such as expanding bladder contents and residual volume, and variable urinary input rate, initial volume and first void time. We have reviewed these publis...

The 3-D view factor code VISRAD is used to both design high energy density physics (HEDP) experiments, and to simulate the multi-dimensional radiation environment within target systems; i.e., hohlraums and associated components such as diagnostic holes, capsules, and backlighters. VISRAD target systems are built using a variety of geometric primitives, and surface removal algorithms (e.g., dril...

Aim: This study sought to evaluate the effects of different irrigation solutions and sterilization processes on surface properties ProTaper Next (PTN; Dentsply-Maillefer, Ballaigues, Switzerland) TruNatomy (TN; Dentsply Sirona, nickel-titanium rotary files. Methodology: 30 files were used. Both types divided into five groups. The in three groups dipped 5.25% NaOCI (CanalPro, Coltene/Whaledent, ...

The first successful high energy density Kelvin-Helmholtz (KH) shear layer experiments (O.A. Hurricane, et al., Phys. Plasmas, 16, 056305, 2009; E.C. Harding, et al., Phys. Rev. Lett., 103, 045005, 2009) demonstrated the ability to design and field a target that produces an array of large diagnosable KH vortices in a controlled fashion. Data from these experiments vividly showed the complete ev...

AIM To study the efficacy of novel rhenium compounds to treat triple node negative breast cancer. PLACE AND DURATION Six (6) novel rhenium pentycarbanato compounds (PC1-6) were synthesized and triple node negative breast cancer cell lines HTB-132 and Balb/c mouse kidney cell lines were treated with each of them for 48 hours. The results were analyzed by a common trypan blue cell death assay s...

During past 3 decades, nuclear medicine has flourished as vibrant and independent medical specialty in Iran. Since that time, more than 200 nuclear physicians have been trained and now practicing in nearly 158 centers throughout the country. In the same period, Tc-99m generators and variety of cold kits for conventional nuclear medicine were locally produced for the first time. Local production...
