Background & Aim: Nucleolin is one of the most abundant proteins in the nucleolus that is overexpressed on the surface of the plasmic membrane of cancer cells. It has been suggested that nucleolin is a new and promising candidate for effective targeted active-targeted delivery of nanoparticles with anti-nucleolin AS1411 aptamer (hereafter Apt), as a single-strand DNA, into a variety of hi...
We present new results on the summation of nonpower-series expansions in QCD Analytic Perturbation Theory (APT) in the one-loop approximation. We show how to generalize the approach suggested by one of us earlier to the cases of APT and Fractional APT (FAPT) with heavyquark thresholds. Using this approach we analyze the Higgs boson decay H → b̄b. We produce estimations of the higher-order correc...
طبق تئوری قیمتگذاری آربیتراژ(APT) بازده واقعی سهام شرکت به مجموعه متنوعی از عوامل کلان ریسک اقصادی ومالی، وهمچنین عوامل خاص شرکت یاصنعت وابسته است. حساسیت بازده یک دارایی به تغییرات پیشبینی نشده درعوامل کلان ریسک بیانگر معیار ریسک سیستماتیک ورقه بهادار است. درحالت تعادل، بازده پیشبینی شده ورقه بهادار تابعی خطی از حساسیتهای بازده واقعی ورقه بهادار به تغییرات پیشبینی نشده در عوامل کلان ر...
در این تحقیق روشی جدید برای تبدیل آمونیوم پاراتنگستات (apt) به کامپوزیت آلومینا- تنگستن ارائه شده است. در این روش تجزیه و احیای apt به طور همزمان و در طول آسیاکاری اتفاق می افتد. بدین منظور از فلز آلومینیم (al) به عنوان عامل احیاکننده استفاده شده است. در مرحله ی اول، با توجه به مجموع واکنش های تجزیه و احیای apt، دو پودر apt و al با نسبت مولی 24:1 مخلوط و در زمان های مختلف آسیاکاری شدند، سپس از...
Activated matrix metalloproteinases (MMPs) cause cardiomyocyte injury during acute pulmonary thromboembolism (APT). However, the functional consequences of this alteration are not known. We examined whether doxycycline (a MMP inhibitor) improves right ventricle function and the cardiac responses to dobutamine during APT. APT was induced with autologous blood clots (350 mg/kg) in anaesthetized m...
BACKGROUND Atopy patch tests (APT) have been introduced as a valuable tool for the diagnosis of food allergy. However, interpretation of the readout of APT requires further clarification. OBJECTIVE To investigate the accuracy of APT in identifying atopic sensitisation to hen's eggs (HE), cow's milk (CM), soybean and wheat in Chinese children with atopic dermatitis (AD) aged less than two year...
Recently, specific attention has been paid to aptamers, short DNA or RNA, as a tool for cancer diagnosis and therapy. In the present study MCS nanogels were prepared by Myristate: chitosan at 1:9 ratio and were characterized by several techniques. A selected ssDNA aptamer(Apt) capable of detecting LNCaP cells was linked to Myristilated chitosan nanogels (Apt-MCS) by glutaraldehyde and loaded wi...
BACKGROUND Atopic dermatitis (AD) is a public health problem, with an increasing prevalence worldwide. AD is a chronic inflammatory disease characterised by skin lesions and severe itching. Immunologically, AD has two forms, IgE-mediated and cell-mediated, but it may also be idiopathic. In the pathogenesis of AD, the gene mutations for filaggrin, a filament-aggregating protein present in the ep...
