A nyirokrendszer, a nyirokerek és nyirokszervek bonyolult hálózata nélkülözhetetlen szerepet játszik a szervezet folyadékegyensúlyának, valamint immunológiai szerepe által a szervezet védekezőképességének fenntartásában. Paradox módon azonban szűrő funkciójából adódóan otthonául szolgálhat a rákos sejtek disszeminációjának is. A szolid tumorok nyirokcsomó-áttéteinek megjelenése rendkívüli jelentőséggel …

Non-Invasive Evaluation of Different Soil Tillage and Seed Treatment Effects on the Microbial Originating Physiological Reactions of Developing Juvenile Maize

Antal Binder, Ildikó Jócsák, Zsolt Varga, Bence Knolmajer et autres

The successful production of maize is fundamentally determined by a good choice of tillage type. Options include conventional tillage based on soil rotation, as well as a more recent conservation approach. Our aims were to determine the stress physiological effects of the …
