Dendritic cells (DCs) are key antigen-presenting cells with a potential role in tumor vaccines. We investigated the hypothesis that early reconstitution of DCs after allogeneic hematopoietic stem cell transplantation (SCT) improves survival. We also correlated DC reconstitution with complications of relapse and acute graft-versus-host disease (aGVHD). Fifty patients underwent transplantation be...

PURPOSE Study goals were to characterize gastrointestinal effects of proton therapy (PT) in a large cohort of patients treated for prostate cancer, identify factors associated with rectal bleeding (RB), and compare RB between patients receiving investigational protocols versus those in outcome-tracking protocols. METHODS AND MATERIALS A total of 1285 consecutive patients were treated with PT ...

مقدمه: استان کرمانشاه یکی از مناطق اندمیک بروز بروسلوز در کشور می باشد به صورتی که این بیماری به عنوان یکی از مشکلات مهم سلامتی منطقه قلمداد می گردد. بررسی مشخصه های دموگرافیک بیماران و روند تغییرات آن می تواند زمینه ساز یافتن گروه های در معرض خطر و همچنین عوامل خطرزا باشد. روش کار: در این بررسی برخی مشخصه های دموگرافیک (شامل سن، جنس، سطح تحصیلات، شغل و محل زندگی) تمامی موارد شناسایی شده بیمارا...

نظریة آشوب ابزاری مناسب برای تحلیل داده‏های دبی جریان رودخانه‏ها درنظر گرفته می‏شود. به دلیل ماهیت دینامیک و غیرخطی جریان رودخانه‏ها، یکی از چالش‏های مهمْ تشخیص رفتار جریان در مقیاس‏های زمانی مختلف است. در تحقیق حاضر، به منظور بررسی آشوب‏پذیری دبی جریان رودخانة کارون در سه مقیاس زمانی روزانه، ماهانه، و فصلی، از آمار 45ساله (1346- 1390) ایستگاه هیدرومتری ملّاثانی استفاده شده است. برای تعیین آشوبنا...

We characterize, classify and axiomatize all subvarieties of IMTL(3), the variety of IMTL-algebras given by the equation ¬(x3) ∨ x ≈ >. We also give a canonical set of generators for each one. Introduction and preliminaries An IMTL-algebra is a bounded residuated lattice A = 〈A,∧,∨, ∗,→,¬,⊥,>〉, where ∧ and ∨ are meet and join, 〈∗,→〉 is a residuated pair, ¬ is the associated negation (i.e. ¬x =d...

This work describes a proposal to improve web document retrieval by facing the main problems in document searching: first, traditional web search engines miss documents that are relevant to the user query and retrieve many that are not. Second, the query formulation is not as accessible as it could be, and some users have difficulties in expressing boolean queries. To improve the quality of Int...
