EXTENSIVE CEREBRAL AND EXTRACEREBRAL METASTASES FROM A LARGE-CELL NEUROENDOCRINE CERVICAL CARCINOMA


VAPA, an innovative "virus-acquisition phenotyping assay" opens new horizons in research into the vector-transmission of plant viruses.

Host-to-host transmission--a key step in plant virus infection cycles--is ensured predominantly by vectors, especially aphids and related insects.A deeper understanding of the mechanisms of virus acquisition, which is critical to vector-transmission, might help to design future virus control strategies, because any newly discovered k2 raygun 2023 m

CONSERVATION TILLAGE METHOD

Water-retaining roughnesses (holes, non-continuous furrows, micro-lagoons) come into being on the field surface at its tillage.They prevent a backflow, an erosion on slope lands and improve moisture content the soil.However, in the last decades such methods of a soil tillage are not used and the equipment for them are not manufactured.The author of
