Introduction: Despite the high incidence of esophageal and thymic carcinoma in human being, co-existence of these two malignant lesions is very rare. In this study we have reported an 81 year old man with a huge mediastinal tumor (Thymoma) and Squamous Cell Carcinoma (SCC) of esophagus. Case report: An 81 year old man presented with hiccups and progressive dysphagia for solids and was admit...
ترانسفکت کردن سلول های استرومایی مغز استخوان با وکتور حامل ژن فاکتور نوروتروفیک مشتق از رده ی سلولی گلیال(gdnf) و ارزیابی بیان آن در محیط in vitro مقدمه : فاکتور نوروتروفیک مشتق از رده ی سلولی گلیال (gdnf) از مهم ترین پروتئین ها در رشد و ترمیم سیستم عصبی است. هر گونه نقص در تولید و ترشح این پروتئین موجب اختلالات مختلفی در بازسازی سلول ها در بیماری های مخرب سیتم عصبی می شود.از گزینه های درمانی ...
Background: Apoptin is a protein from chicken anemia virus that could induce apoptosis specifically in the cancer cells but it has not any effect in the normal cells. Phage therapy is a novel field of cancer therapy and phage nanobioparticles (NBPs) such as λ phage could be modified to deliver and express genetic cassettes into eukaryotic cells safely in contrast with animal viruses. The bacter...
چکیده اساسی ترین منبع استراتژیک هر سازمان یا جامعه،منابع انسانی می باشد.جوامع موفق،جوامعی هستند که بتوانند منابع انسانی خود را به طور صحیح پرورش و توسعه دهند. در اقتصاد امروز، دانش به عنوان مهمترین سرمایه، جایگزین سرمایه مالی و فیزیکی شده است . دانش و اطلاعات به رشد اقتصادی کمک می کند.این امر موجب افزایش اهمیّت سرمایه فکری به عنوان مقوله ای پژوهشی شده است. مدیریت منابع انسانی یعنی مدیریت و ادار...
Objective(s): Somatostatin receptor-positive neuroendocrine tumors have been targeted using various peptide analogs radiolabeled with therapeutic radionuclides for years. The better biomedical properties of radioantagonists as higher tumor uptake make these radioligands more attractive than agonists for somatostatin receptor-targeted radionuclide therapy. In this study...
Background: Essential oils are found to have multiple active components which can show in vitro cytotoxic action against various cancerous cell lines. This study reports the in vitro cytotoxic effects of the essential oil from Artemisia absinthium L. (Asteraceae) growing wild in Iran. Methods: Water-distilled essential oil of A. absinthium collected from Ardabil, north-western Iran, was examin...
purpose: to present a case of orbital granular cell tumor, a rare orbital tumor. case report: a 55-year-old woman presented with binocular diplopia and right ocular displacement. the problem had initiated 3 years ago. a firm nontender mass at the region of the right lower lid was visible. orbital ct-scan disclosed a well-defined mass in the inferior right orbit with involvement of the inferior ...
results there was no statistical difference between the 2 groups with respect to the recurrence rate (p > 0.05). although the recurrence interval was longer for the metformin group, this increase was not statistical significant (p > 0.05). furthermore, tumor recurrence had no correlation with sex or the grade of the tumors. conclusions according to our findings, it seems that metformin has no c...
results a low adc value was associated with lymph node metastasis (p < 0.01) and with high ki-67 protein levels (p = 0.03). there were no significant differences in the adc values among the histological grade (p = 0.48), molecular subtype (p = 0.51), tumor size (p = 0.46), and p53 protein level (p = 0.62). conclusion the pre-operative use of the 3.0 tesla dwi could provide information about the...
