Cancer/Testis antigens (CTAs) as a group of tumor antigens are the novel subjects for developing cancer vaccine and immunotherapy approaches. They aberrantly express in tumors with highest normal expression in testis, and limited or no expression in normal tissues. There are important similarities between the processes of germ-cell and cancer cell development Spermatogenesis begins at puberty w...
In the present study, a set of self-designed measurement protocols for the precision of coaxial needle placement (PCNP) was proposed and applied in a computed tomography (CT)-guided transthoracic needle biopsy (TNB) audit of an interventional radiologist to determine if the PCNP was commensurate with the experience of the operator. A total of 102 patients (98 with lung lesions and four with med...
Conjugated donor-acceptor block co-oligomers that self-organize into D-A mesomorphic arrays have raised increasing interest due to their potential applications in organic solar cells. We report here a combined experimental and computational study of charge transfer (CT) state formation and recombination in isolated donor-spacer-acceptor oligomers based on bisthiophene-fluorene (D) and perylene ...
Critical thinking (CT) is one of the most important 21st-century skills that employers believe will grow in prominence. However, many higher education (HE) graduates often lack it. This also true for computer science (CS) and related disciplines, who need CT to drive social organizational digitalization. There are a number strategies teaching CT. there no evidence regarding how effectively teac...

introduction: cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. the necessity for imaging in an uncomplicated case is controversial. this study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (hrct) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the...
introduction in computed tomography (ct) technology, an optimal radiation dose can be achieved via changing radiation parameters such as ma, pitch factor, rotation time and tube voltage (kvp) for diagnostic images. materials and methods in this study, the brain, abdomen, and thorax scaning was performed using toshiba 16-slice scannerand standard aapm and ctdi phantoms. aapm phantom was used for...
ترکیبات 3-هیدروکسی-2-اکسیندول در طبیعت یافت می شوند. این ترکیبات دارای تنوع در فعالیت بیولوژیکی و دارویی مثل ضد سرطان، ضد hiv و آنتی اکسیدانت هستند که با توجه به استخلاف های مختلف روی موقعیت سه ترکیب پایه 3-هیدروکسی-2-اکسیندول این خواص متفاوت را نشان می دهد. بررسی برهم کنش ترکیب سنتزی جدید اکسیندول a (5-(2-هیدروکسی-2-اکسو-2،3-دی هیدرو-1 هیدروژن-ایندول-3-ایل)-1،3 تیازولیدین-2،4-دیون) با dna در ح...
trauma is the most common reason in 1-34 years olds. in patient with multiple traumas, the head is the most common involved part. the importance of computed tomography (ct scan) in diagnosis of brain trauma is well established and ct of the brain is a choice method. finding lesion in brain traumatic patient is very important so goal of this study is finding of brain ct scan in traumatic patient...
