Solar energy

This article is about the development of renewable sources in the form of solar energy. It features comprehensive discussions of many aspects of solar energy development in Russia and around the world. The purpose this article is to tell about advantages of solar energy

Lithium and magnesium isotopes fractionation by zone melting

The process of changing isotopic composition of the lithium and magnesium salts was studied by using the process of zone melting. It was founded in the paper that the process of separation of the lithium isotopes is more effective than for magnesium isotopes when the conditions of process were the same. The coefficients of isotopes separation were calculated and have the next value: [alpha]=1.006 for 26Mg isotope and [alpha]=1.0022 for {6}Li isotope

CONFOCAL MICROSCOPY STUDY OF BIOLOGICAL PECULIARITIES OF SCAFFOLD MADE FROM RECOMBINANT SPIDER SILK

We studied the viability and dynamic of cell distribution during long-term cultivation of broblasts 3T3 in spider silk spidroin 1-based scaffold. Laser scanning confocal microscopy is shown to have advantages for visualization of cells situated on the external and internal surfaces of scaffold. Fibroblasts maintain high proliferative ability and viability during long term cultivation. Spidroin 1-based scaffold are the perspective materials for bioengineering

ИСПОЛЬЗОВАНИЕ МЕТОДА КОНФОКАЛЬНОЙ МИКРОСКОПИИ ДЛЯ ИЗУЧЕНИЯ БИОЛОГИЧЕСКИХ СВОЙСТВ МАТРИКСА ИЗ РЕКОМБИНАНТНОЙ ПАУТИНЫ

We studied the viability and dynamic of cell distribution during long-term cultivation of broblasts 3T3 in spider silk spidroin 1-based scaffold. Laser scanning confocal microscopy is shown to have advantages for visualization of cells situated on the external and internal surfaces of scaffold. Fibroblasts maintain high proliferative ability and viability during long term cultivation. Spidroin 1-based scaffold are the perspective materials for bioengineering. Изучена жизнеспособность и динамика распределения мышиных фибробластов 3T3 в матрице на ос- нове рекомбинантного белка каркасной нити паутины спидроина 1 при длительном культивировании. Показана возможность и преимущества использования конфокальной микроскопии как для визуализа- ции клеток, находящихся в глубоких слоях трехмерной матрицы, так и для наблюдения за изменением состояния культивируемых клеток. Популяция фибробластов сохраняла высокие показатели жизнеспо- собности и пролиферативной активности, а инфильтрация матрицы клеточной популяцией становилась однородной в течение длительного времени культивирования. Это позволяет рассматривать матрицы на основе спидроина 1 в качестве перспективного материала для создания биоинженерных конструкций.
