triptoreline is a potent agonist of luteinizing hormone-releasing hormone, currently used in the treatment of prostatic cancer where therapy may be required over months or years. frequent injection of drug decreases patients’ compliance. the present study describes the formulation of a sustained release microparticulate drug delivery system containing triptoreline acetate, using poly (d,l lacti...
fusion is a rare occurrence in molar teeth. the purpose of this rare case presentation is to describe the nonsurgical endodontic treatment of maxillary molar. a 28-year-old patient was referred for endodontic treatment of her chronic apical abscess of right maxillary second molar. in the clinical examination, a sinus tract adjacent to involved tooth and a small crown of supernumerary tooth fuse...
background: patients which have diagnosed with a cancer, have a life time risk for developing another de novo malignancy depending on various inherited, environmental and iatrogenic risk factors. cancer victims could survive longer due to settling treatment modalities, and then would likely develop a new metachronous malignancy. this article aims to report our observed trend of increasing, in p...
Cu/Ti3SiC2/C/BN/GNPs nanocomposites were prepared by vacuum hot-pressing (HP) sintering and hot isostatic pressing (HIP) sintering methods. Microstructures, mechanical and tribological properties of Cu/Ti3SiC2/C/BN/GNPs nanocomposites were investigated. Microstructures were examined by optical microscopy (OM), X-ray diffraction (XRD) and scanning electron microscope (SEM). Mechanical properties...
In this thesis, we report on a process to obtain yttrium oxide nanosized particles doped with ytterbium and a sintering method that leads to transparent polycrystalline ceramics. First, nano-powder of yttria was fabricated from a precursor with transient morphology, i.d. yttrium hydroxynitrate platelets that decompose into spherical yttria nano-particles during calcination. The influence of dif...
Symmetric aromatic diselenides are potential anticancer agents with strong cytotoxic activity. In this study, the in vitro anticancer activities of a novel series of diarylseleno derivatives from the diphenyldiselenide (DPDS) scaffold were evaluated. Most of the compounds exhibited high efficacy for inducing cytotoxicity against different human cancer cell lines. DPDS 2, the compound with the l...
in this paper we introduce some new double sequence spaces using the orlicz function andexamine some properties of the resulting sequence spaces.
هدف این مقاله درباره معنا ونمادی است که مفاهیم نقاب‘ همزاد و دیگری دربرخی از آثار شاعر و نویسنده نامدار مکزیکی ‘ اکتاویوپاز octavio paz ‘ در بر دارند. در حالی که بیش از هر چیز تکیة مقاله بر روی شاهکار‘ وی هزار توی تنهایی است که عنوان فرعی زندگی و نگرش مکزیکی را دارد. در ادامه‘ از یک سو در مورد این که چگونه اکتاویوپاز به افشای هویت مکزیکی که مدام در پس نقاب‘ همزاد و دیگری خود را پنهان می کند برر...
