سابقه و هدف: نانو ذرات نقره با دارا بودن خواص ضد میکروبی بسیار قوی، مقبولیت بالایی در پزشکی و دندانپزشکی یافته‌اند. اما علی رغم کاربردهای وسیع، اطلاعات کافی در رابطه با تاثیر آنها بر روی سلامت انسان وجود ندارد و مواردی مبنی بر سمیت آنها گزارش شده است. این مطالعه با هدف بررسی سمیت نانوذرات نقره بر روی سلول های فیبروبلاست رده‌ی L929 به روش MTT انجام گرفت . مواد و روش‌ها: در این مطالعه‌ی تجربی - ...
The objective of this thesis is to develop a new framework for Multi-Target Tracking (MTT) algorithms that are distinguished by the use of statistical machine learning techniques. MTT is a crucial problem for many important practical applications such as military surveillance. Despite being a well-studied research problem, MTT remains challenging, mostly because of the challenges of computation...
The mean transit time (MTT), coefficient of variation (CoV), and index of skewness (IoS) of transit times of the forced expiratory flow/time curve have been compared with maximal mid-expiratory flow (MMEF), flow at 75, 50, and 25% of vital capacity (V75, V50, and V25), and the ratio of forced expiratory volume in 1 second (FEV1) to vital capacity (VC) in 51 asthmatic children judged on clinical...
Are humans alone in their ability to reminisce about the past and imagine the future? Recent evidence suggests that food-storing birds (scrub jays) have access to information about what they have stored where and when. This has raised the possibility of mental time travel (MTT) in animals and sparked similar research with other species. Here we caution that such data do not provide convincing e...
MTW9, a transplantable mammary tumor in Wistar Furth rats, shows little growth unless host serum prolactin is increased. This study compares the response to ovariectomy of MTW9-MtT, a tumor developed in rats bearing the mammosomatotropic tumor MtTW10 (serum prolactin 500 to 7000 ng/ml) with MTW9-P developed in rats given chronic perphenazine treatment (4 mg/kg/day). Serum prolactin concentratio...
In our study, it was aimed to create a new drug delivery system by loading the chemotherapeutic drugs into exosome vesicles. This act as Trojan horse targeting GBM cancer. Exosomes were isolated from T-98G cell line and characterized. encapsulated with Temozolomide. Then, effectiveness of this evaluated using MTT, LDH, TAC, TOS, GR. 
 MTT results show dose-dependent decrease in TMZ Exolime...
BACKGROUND AND PURPOSE There is ample evidence that in anterior circulation stroke, the diffusion-weighted imaging (DWI) lesion may escape infarction and thus is not a reliable infarct predictor. In this study, we assessed the predictive value of the mean transit time (MTT) for final infarction within the DWI lesion, first in patients scanned back-to-back with 15O-positron emission tomography a...
