Digitalization in management accounting and control: an editorial.

Digitalization has the potential to disrupt the management accounting domain. It may not only affect the digital landscape of the organization and the associated business models, but also management accounting and control practices as well as the role of the controller. This editorial discusses these developments by introducing the concept of digitalization and describing its impact on the field of management accounting and control.

Targeted purification of SnAvi-tagged proteins.

Tandem affinity purification (TAP) is a powerful technique to identify protein complex members. The modular composition of TAP-tags allows two sequential protein enrichment steps and thereby drastically reduces the amount of contaminants. Here, we describe the application of the SnAvi-tag-a TAP-tag useful in different expression systems.

Muscle histopathology in nebulin-related nemaline myopathy: ultrastrastructural findings correlated to disease severity and genotype.

Nemaline myopathy (NM) is a rare congenital myopathy characterised by hypotonia, muscle weakness, and often skeletal muscle deformities with the presence of nemaline bodies (rods) in the muscle biopsy. The nebulin (NEB) gene is the most commonly mutated and is thought to account for approximately 50% of genetically diagnosed cases of NM. We undertook a detailed muscle morphological analysis of 14 NEB-mutated NM patients with different clinical forms to define muscle pathological patterns and correlate them with clinical course and genotype.

SnAvi--a new tandem tag for high-affinity protein-complex purification.

Systematic tandem-affinity-purification (TAP) of protein complexes was tremendously successful in yeast and has changed the general concept of how we understand protein function in eukaryotic cells. The transfer of this method to other model organisms has been difficult and may require specific adaptations. We were especially interested to establish a cell-type-specific TAP system for Caenorhabditis elegans, a model animal well suited to high-throughput analysis, proteomics and systems biology.

[Expression of c-erbB-2 and topoisomerase II alpha in relation to chemoresistance in ovarian cancer].

In the present study, we examined die role of c-erbB-2 for chemoresistance in ovarian cancer. Overexpression of c-erbB-2 mRNA in tumor tissue was associated with a shorter survival of patients with primary ovarian cancer (P = 0.0001, N = 77) and was an independent prognostic factor in the proportional-hazard model (P = 0.
