در این پایان نامه یک روش شیمیایی برای لایه نشانی لایه های نازک نانوکریستال cus با استفاده از محلول آبی مس استات تک آبه (منبع مس)، تیواستامید (منبع گوگرد) وتری سدیم سیترات (عامل کمپلکس ساز) در دمای اتاق، پیشنهاد شده است. در این تحقیق، آب به عنوان حلال و تری سدیم سیترات به عنوان عامل کمپلکس ساز هر دو از مواد شیمیایی غیر سمی و تجدیدپذیر می باشند. لایه ها به وسیله الگوی پراش اشعه ی ایکس،xrd، آنالیز...
BACKGROUND AND PURPOSE Brain imaging is an integral part of the diagnostic work-up for metabolic disorders, and the bedside availability of cranial ultrasonography (cUS) allows very early brain imaging in symptomatic neonates. Our aim was to investigate the role and range of abnormalities seen on cUS in neonates presenting with metabolic disorders. A secondary aim, when possible, was to address...
Copper sulfide nanoparticles (CuS NPs) have been reported as a single-compartment theranostic nanosystem to visualize and treat tumors simultaneously. However, few studies have investigated the in vivo tumor-targeted delivery of this class of nanoparticles. In this study, we introduced a tumor-specific targeting ligand, folic acid (FA), onto the surface of CuS NPs as a model system to demonstra...
An efficient Hydrogen evolution catalyst has been developed by decorating Au nanoparticle on the surface of CuS nanostructure following a green and environmental friendly approach. CuS nanostructure is synthesized through a simple wet-chemical route. CuS being a visible light photocatalyst is introduced to function as an efficient reducing agent. Photogenerated electron is used to reduce Au(III...
OBJECTIVE To evaluate the diagnostic accuracy of cranial ultrasound (CUS) for detection of neonatal arterial territory cerebral infarction in term infants. METHODS CUS scans from term infants with neonatal magnetic resonance imaging (MRI) evidence of neonatal infarction were reviewed. The scans were grouped by acquisition time after birth: 1-3 days (early) or 4-14 days (late). RESULTS Brain...
Establishing a diagnosis of recurrent deep vein thrombosis (RDVT) by compression ultrasonography (CUS) is often difficult because persistent abnormal findings of the deep veins are common after a first episode of DVT. This may lead to a high percentage of potential misclassified patients with ipsilateral RDVT. The objective of the study is to evaluate the diagnostic management of ipsilateral RD...
OBJECTIVE To evaluate the contribution of sequential cranial ultrasound (cUS) and term-equivalent age magnetic resonance imaging (TEA-MRI) including diffusion weighted imaging (DWI) to the early prognosis of neurodevelopmental outcome in a cohort of very preterm infants (gestational age [GA] <31 weeks). STUDY DESIGN In total, 93 preterm infants (median [range] GA in weeks: 28.3 [25.0-30.9]) w...
Epidermal growth factor receptor (EGFR) overexpression is related to the increased aggressiveness, metastases, and poor prognosis in various cancers. In this study, we successfully constructed a new EGFR nanobody-based immunotoxin rE/CUS containing cucurmosin (CUS), The immunotoxin was expressed by prokaryotic system and we obtained a yield of 5 mg protein per liter expression medium. The perce...
OBJECTIVE The present study aimed to investigate whether graded doses of Bacopa Monniera (BM) extract could produce antidepressant-like effects in chronic unpredictable stress (CUS) induced depression in rats and its possible mechanism(s). METHODS Rats were subjected to an experimental setting of CUS. The effect of BM extract treatment in CUS-induced depression was examined using behavioral t...
طی سالهای اخیر، فرایند فتوکاتالیستی نیمرساناها برای حذف ترکیبات آلی از آب، توجه زیادی را به دلیل پتانسیل این فرایند بهعنوان یک فناوری تصفیه کمهزینه و دوستدار محیطزیست به خود جلب کرده است. در این پژوهش با هدف بهدست آوردن مقدار بهینه محتوای CuS و CdS در نانوفتوکاتالیستهای CuS-CdS/TiO2، چهار نمونه با مقدارهای متفاوت CuS و CdS با روش آب گرمایی سنتز شدند. نمونههای سنتز شده با روشهای XRD، F...
