ИАТЭ НИЯУ МИФИ
ИАТЭ НИЯУ МИФИ был образован в 1953 г. как вечернее отделение МИФИ. В 2009 г. ИАТЭ официально получил статус обособленного структурного подразделения НИЯУ «МИФИ», что дало новый мощный импульс для развития образовательной и научной деятельности на основе инновационной составляющей. В соответствии с лицензией Минобрнауки России ИАТЭ ведет образовательную деятельность в рамках очной, очно-заочной и заочной форм обучения. В настоящее время в ИАТЭ НИЯУ МИФИ осуществляется подготовка по очной форме обучения: бакалавриат- 16 направлений, специалитет – 4 направления, магистратура- 12 направлений; по очно-заочной: бакалавриат- 4 направления, специалитет – 1 направление; по заочной: бакалавриат- 3 направления, специалитет- 2 направления; аспирантура – 18 направлений.
В структуре ИАТЭ 9 факультетов: физико-энергетический, естественных наук, кибернетики, социально-экономический, медицинский, вечерний, заочного обучения, подготовительный, повышения квалификации и профессиональной переподготовки специалистов. Образовательный процесс обеспечивают 18 общеобразовательных и 22 выпускающие кафедры.

- ПубликацияОткрытый доступAmylase-sensitive polymeric nanoparticles based on dextran sulfate and doxorubicin with anticoagulant activity(2019) Pyataev, N. A.; Petrov, P. S.; Minaeva, O. V.; Zharkov, M. N.; Kokorev, A. V.; Кокорев, Александр Викторович© 2019 by the authors.This study looked into the synthesis and study of Dextrane Sulfate-Doxorubicin Nanoparticles (DS-Dox NP) that are sensitive to amylase and show anticoagulant properties. The particles were obtained by the method of solvent replacement. They had a size of 305 ± 58 nm, with a mass ratio of DS:Dox = 3.3:1. On heating to 37 °C, the release of Dox from the particles was equal to 24.2% of the drug contained. In the presence of amylase, this ratio had increased to 42.1%. The study of the biological activity of the particles included an assessment of the cytotoxicity and the effect on hemostasis and antitumor activity. In a study of cytotoxicity on the L929 cell culture, it was found that the synthesized particles had less toxicity, compared to free doxorubicin. However, in the presence of amylase, their cytotoxicity was higher than the traditional forms of the drug. In a study of the effect of DS-Dox NP on hemostasis, it was found that the particles had a heparin-like anticoagulant effect. Antitumor activity was studied on the model of ascitic Zaidel hepatoma in rats. The frequency of complete cure in animals treated with the DS-Dox nanoparticles was higher, compared to animals receiving the traditional form of the drug.
- ПубликацияОткрытый доступMethod of detection of dexamethasone in biological tissues and its application to assess the local kinetics of this drug(2023) Yunina, D. V.; Ageev, V. P.; Tararina, L. A.; Tsaregorodtsev, S. V.; Kokorev, A. V.; Кокорев, Александр ВикторовичIntroduction: The study of the pharmacokinetics of glucocorticosteroids is often required to solve fundamental and applied tasks of pharmacology. HPLC methods based on ultraviolet detection are attractive due to their availability, but their sensitivity is low enough to study in vivo kinetics. In this study, we propose a method for the determination of dexamethasone in biological objects, based on the use of HPLC with UV detection and having sufficient sensitivity to determine the drug in biological media (blood and periarticular tissues). Materials and methods: Extraction of dexamethasone from biosamples was carried out by liquid-liquid extraction with acetone in an acidic medium using atenolol as an internal standard. The analysis was carried out on a Kromasil-100 C18 column. A mixture of methanol with phosphate buffer in the ratio 50Г·50, pH=5.6 was used as the mobile phase. Detector - UV, wavelength - 254 nm. The LLOQ of the method was 50 ng/mL; the calibration curve demonstrated linearity in the con-centration range of 50-1000 ng/mL.The method was used to detect the medicinal product in peri-synovial tissues of rats with an autoimmune arthritis model. Results: This study demonstrated that intraarticular injection of the liposomal form of dexamethasone, compared with its water-soluble form, allows maintaining the active concentration of the product in the joint and periarticular tissues for a longer time, which creates prerequisites for enhancing its therapeutic effect. Conclusion: The proposed method provides a sensitive and specific approach for measuring dexamethasone in biological samples, such as blood and periarticular tissues. Preliminary findings indicate that the liposomal form of dexamethasone may exhibit better pharmacokinetic properties than the water-soluble form, which could lead to improved therapeutic outcomes.
- ПубликацияТолько метаданныеComparative Efficacies of Doxorubicin Complexes with Dextran Phosphate and Dextran Sulfate for Intracavity Chemotherapy of Zajdela Ascitic Hepatoma in Rats(2019) Minaeva, O. V.; Petrov, P. S.; Kulikov, O. A.; Zaborovskii, A. V.; Kokorev, A. V.; Кокорев, Александр Викторович© 2019, Springer Science+Business Media, LLC, part of Springer Nature.The efficacies of doxorubicin (Dox) complexes with carbohydrate polymers dextran phosphate (DP) and dextran sulfate (DS) in rats with grafted Zajdela ascitic hepatoma were studied in two series of experiments. The first studied the effects of the synthesized complexes on the cure rate and lifespan of the animals; the second, effects on ascites morphological parameters and Dox concentration in ascites fluid. The complexes were injected i.p. at a dose of 2 mg Dox/kg. The results showed that the Dox-DS complex reduced the lethality by 50% as compared with water-soluble Dox; the Dox-DP complex, by 28%. These complexes decreased statistically significantly the amount of ascites fluid and tumor-cell concentration in it. The drug was detected in ascites fluid 2 d after administration of Dox-DS and Dox-DP. The concentration of active ingredient in ascites fluid in animals treated with Dox-DS was >4 times higher than that in those treated with Dox-DP.
