Pneumatic retinopexy is a minimally invasive, non-incisional procedure for repairing retinal detachment. This procedure is associated with reduced morbidity, reduced cost and faster postoperative recovery compared to pars plana vitrectomy and scleral buckling. Superior visual acuity outcomes have also been reported. Intraoperative complications are primarily related to the intraocular pressure ...
Protein synthesis is the ultimate step of gene expression and a key control point for regulation. In particular, it enables cells to rapidly manipulate protein production without new mRNA synthesis, processing, or export. Recent studies have enhanced our understanding of the translation initiation process and helped elucidate how modifications of the general translational machinery regulate gen...
We have previously identified (M. Wang et aL, OncoL Res., in press, 1998) an enhancer element [human tissue inhibitor of metalloproteinase-1 enhancer-i (HTE)] for the human tissue inhibitor of metalloproteinase-1 promoter that binds a novel zinc finger, cysteine-rich transcription factor (CRTF). In this study, we have used electrophoretic mobifity shift assays to examine the relative level of e...
mining and metallurgical projects are among those that require the most sizeable invest-ments undertaken in iran. one target of the current development plan and the ministry of mines and industries has been to attract foreign investment in mining projects. a survey of world-class mining companies was conducted to determine their expectations and in order to recommend a frame work for iran aimed...
The history of life is fi lled with examples of one species diverging into several, even thousands, each with unique traits geared to the demands of its ecological niche. In the textbook case of adaptive radiation, an ancestral fi nch species landed on the Galapagos Islands just a few million years ago, and evolved into 13 new species with specialized beaks adapted to exploiting the various see...
Factorization methods are used extensively in computer vision for a wide variety of tasks. Existing factorization techniques extract factors that meet requirements such as compact representation, interpretability, efficiency, dimensionality reduction etc. However, when the extracted factors lack interpretability and are large in number, identification of factors that cause the data to exhibit c...
it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
Introduction Based on Task Group No. 43 (TG-43U1) recommendations, water phantom is proposed as a reference phantom for the dosimetry of brachytherapy sources. The experimental determination of TG-43 parameters is usually performed in water-equivalent solid phantoms. The purpose of this study was to determine the conversion factors for equalizing solid phantoms to water. Materials and Methods T...
