[The practical training of medical students in General Medicine: Important characteristics of teaching practices].

Background: Comprehensive general medical care is endangered by the socio-demographic development of the population as well as by recruitment problems in general medicine. Medical students' interest in general medicine increases if they experience their internships positively. However, the characteristics of teaching practice important to medical students have not been systematically investigated.

Biogenesis of a specialized plant-fungal interface during host cell internalization of Golovinomyces orontii haustoria.

Powdery mildew fungi are biotrophic pathogens that require living plant cells for their growth and reproduction. Elaboration of a specialized cell called a haustorium is essential for their pathogenesis, providing a portal into host cells for nutrient uptake and delivery of virulence effectors. Haustoria are enveloped by a modified plant plasma membrane, the extrahaustorial membrane (EHM), and an extrahaustorial matrix (EHMx), across which molecular exchange must occur, but the origin and composition of this interfacial zone remains obscure.

High-throughput confocal imaging of intact live tissue enables quantification of membrane trafficking in Arabidopsis.

Membrane compartmentalization and trafficking within and between cells is considered an essential cellular property of higher eukaryotes. We established a high-throughput imaging method suitable for the quantitative detection of membrane compartments at subcellular resolution in intact epidermal tissue. Whole Arabidopsis (Arabidopsis thaliana) cotyledon leaves were subjected to quantitative confocal laser microscopy using automated image acquisition, computational pattern recognition, and quantification of membrane compartments.
