آزمون‌های رئولوژیکی تحت میدان جریان برشی گذار و دینامیک به همراه آزمون‌های SAXS، TEM و SEM برای آمیخته‌های PP/PET با نسبت‌های وزنی 75/25 و 25/75 حاوی دو نوع نانوخاک‌رس مونت‌موریلونیت با نام‌های تجاری کلویزیت 20A و کلویزیت 30B، انجام شد. نسبت وزنی کلویزیت 20A به کلویزیت 30B در نمونه‌های نانوکامپوزیت آمیخته برابر با نسبت وزنی PP به PET انتخاب شد. نتایج آزمون‌های SAXS و TEM نشان داد، تقریباً تمام ن...
Abstract Consolidative radiation therapy (RT) for advanced-stage diffuse large B-cell lymphoma (DLBCL) remains controversial, with routine practice continuing to include RT in patients initial bulky disease or residual masses. Positron emission tomography (PET)-computed is a sensitive modality detecting the presence of at end treatment (EOT). A PET-guided approach selectively administering has ...
Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GIST has been shown to over-express c-KIT (CD117), the receptor tyrosine kinase. Imatinib (STI571 or Glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to trea...
Bladder herniation is an uncommon condition mimicking suspicious metastasis on PET/CT imaging. We report a 67 y/o man with prostate cancer referred for recurrence evaluation with 68Ga-PSMA-11 PET/CT. The scan showed an asymmetric site of intense tracer accumulation in the left inguino-scrotal region with the same SUVmax to the pelvic bladder. Reviewing cross sectional CT i...
In this research, sunflower oil that was extracted and refined at Shiraz Narges Oil Company was packed in four different containers, namely, clear PET (polyethylene terephtalate), yellow PET, yellow HDPE (high density polyethylene), and metal can. Samples were kept at ambient temperature in the shelf exposed to normal light for a period of 1 year. Peroxide values were determined at 45-day inter...
Combined PET/CT scanners now play a major role in medicine for in vivo imaging in oncology, cardiology, neurology, and psychiatry. As the performance of a scanner depends not only on the scintillating material but also on the scanner design, with regards to the advent of newer scanners, there is a need to optimize acquisition protocols as well as to compare scanner ...

در این تحقیق ژن np با استفاده از سایت www.encorbio.com/protocols/codon.htm به گونه ای طراحی شده است که حاوی نوکلئو تیدهای تغییر یافته مناسب میزبان ( e.coli) باشد. توالی ژن از طریق شرکت ندای فن سنتز گردید . ساب کلونینگ np در pet-22b: ابتدا ژن np و وکتور pet-22b با آنزیمهای noti و hindiii برش داده شده و ژن np از pge-vector خارج گردید.سپس وکتور و ژن فوق در واکنش ligation وارد گردیده و در e.coli ...
conclusion the fdg pet/ct showed a high sensitivity and a high negative predictive value for identifying malignancies in thyroid nodules with indeterminate fnab results. therefore, the fdg pet/ct may be a helpful tool in the clinical management of these nodules. when an fdg positive lesion is detected, further examination is recommended. background thyroid nodules with indeterminate fine-needle...
Interim 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (I-PET/CT) is a powerful tool for monitoring the response to therapy in diffuse large B-cell lymphoma (DLBCL). This retrospective study aimed to determine when and how to use I-PET/CT in DLBCL. A total of 197 patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) w...
