Some microalgae in nature live in symbiosis with microorganisms that can enhance or inhibit growth, thus influencing the dynamics of phytoplankton blooms. In spite of the great ecological importance of these interactions, very few defined laboratory systems are available to study them in detail. Here we present a co-cultivation system consisting of the toxic phototrophic dinoflagellate Prorocen...
The abnormal proliferation of vascular smooth muscle cells (VSMC) is thought to play a role in the pathogenesis of atherosclerosis. Adipocytes produce several bioactive paracrine substances that can affect the growth and migration of VSMCs. Our study focuses on the direct effect of the bioactive substances in conditioned media (CM) that was obtained by incubation with primary adipocyte-derived ...
The blood-air barrier is a most important functional element of the lung but little information is available about the cells constituting this barrier in vivo. The aim of the present study was to create an in vitro model of the blood-air barrier that would allow investigation of cellular interactions and alveolar metabolism, and would be suitable for in vitro drug screening. Rat pneumocytes and...
Standard cultivation fails to grow most microorganisms, whereas in situ cultivation allows for the isolation of comparatively diverse and novel microorganisms. Information on similarities and differences in the physiological properties of isolates obtained from in situ cultivation and standard cultivation is limited. Therefore, we used the arctic sediment samples and compared two culture collec...
Olive oil production is associated with extremely polluting byproducts causing serious environmental problems in most Mediterranean countries. These highly polluting residues are currently disposed of in the soil, rivers or lakes or where treatment methods have been applied, they were proven insufficient or nonfeasible under the Greek situation. On the other hand strict EU environmental legisla...
Novel microbial cultivation platforms are of increasing interest to researchers in academia and industry. The development of materials with specialized chemical and geometric properties has opened up new possibilities in the study of previously unculturable microorganisms and has facilitated the design of elegant, high-throughput experimental set-ups. Within the context of the international Gen...
It is known that multipotent stromal cells (MSCs) and thymocytes possess membrane affinity and interaction in the thymic niches that is essentially important for thymocytes differentiation. However there are no data about possible influence of intercellular contacts in the reverse direction: from the thymocytes to the MSCs. MATERIALS AND METHODS. The MSCs were obtained from the thymuses of С57В...
System of Rice Intensification (SRI) paddy was introduced to offset the heavy cost of Traditional paddy cultivation. To decrease the cost of cultivation in Traditional paddy, to increase profits of the farmers in rice cultivation by decreasing the use of fertilizers, pesticides and minimizing water use by scientific water management in the face of labour scarcity, SRI paddy was introduced in Ma...
Rain-shelter cultivation is an effective cultural method to prevent rainfall damage during grape harvest and widely applied in the Chinese rainy regions. In this study we investigated the effect of rain-shelter cultivation on grape diseases and phenolic composition in the skins of Vitis vinifera cv. Cabernet Gernischet grape berries through the comparison with open-field cultivation at two vint...
