The use of quantum dots (QDots) as bright and photostable probes for long-term fluorescence imaging is gaining more interest. Thus far, (pre)clinical use of QDots remains limited, which is primarily caused by the potential toxicity of QDots. Most QDots consist of Cd2+ ions, which are known to cause high levels of toxicity. Therefore, the cytotoxic effects of CdSe quantum dots on embryonic devel...
Introduction: One of the useful standard quality assurance techniques in radiation therapy is monitoring entrance doses in in-vivo dosimetry. An overall tolerance limit of 5% of the absorbed radiation dose has been recommended by the International Commission of Radiological Units. The implementation of an in vivo dosimet...
purpose: to describe a novel surgical technique for in vivo limbal stem cell cultivation for reconstruction of corneal epithelium in total limbal stem cell deficiency (lscd). methods: patients suffering from chronic total unilateral lscd due to a chemical injury were sequentially included. one small limbal block (2x1 mm) harvested from contralateral healthy eye sutured over the amniotic membran...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
این مطالعه در 2 بخش in vitro وin vivo انجام شده است. در بخش in vitro سلول های بنیادی از بافت چربی موجود در اطراف کلیه های موش بالغ صحرایی استخراج شد و تا 4 پاساژ سلولی کشت داده شدند. سلول های بنیادی بافت چربی در طی دو مرحله پیش القاء (با دپرنیل) و القاء با shh و رتینوئیک اسید) به سلول های شبه عصبی حرکتی متمایز شدند. سلول های بنیادی بافت چربی توسط نشان گرهای cd90, cd49d, cd31, cd45 مورد ارزیابی ...

Background: According to the drug resistance and side effects of the standard treatments for leishmaniasis, achieving effective treatment with less side effects and more benefits is of paramount importance. The present study aimed to evaluate the effect of Aloe vera leaf exudate on Leishmania major under in vitro and in vivo models, in inbred BALB/c mice. Methods: Different concentrations of bo...
Drug-induced cholestasis is the main type of liver disorder accompanied by high morbidity and mortality. Evidence for the role of hepatobiliary pumps in the cholestasis patho-mechanism is constantly increasing. Recognition of the interactions of chemical agents with these transporters at the initial phases of drug discovery can help develop new drug candidates with low cholestasis potential. Th...
