BACKGROUND In rare condition, combined thymic epithelial tumors showing either type A or type B thymomas areas combined with thymic carcinoma components may occur in thymus. Mucoepidermoid carcinoma (MEC) of the thymus is rare in thymic carcinoma, and so far there is no report to describe a combined epithelial tumor of thymus with MEC component. We report an unusual case of combined thymic MEC/...

The Wnt-\ proto-oncogene is transcriptionally activated by mouse mammary tumor virus in mouse mammary tumor virus-induced tumors. Previous studies using transgenic mice showed that \\'nt-\ expression in mammary gland causes alveolar hyperplasias which resemble mam mary glands of pregnant mice. To understand the role of mammogenic hormones in the genesis of these hyperplasias, we examined the de...

Principal neurons in different medial entorhinal cortex (MEC) layers show variations in spatial modulation that stabilize between 15 and 30 days postnatally. These in vivo variations are likely due to differences in intrinsic membrane properties and integrative capacities of neurons. The latter depends on inputs and thus potentially on the morphology of principal neurons. In this comprehensive ...

BACKGROUND To establish the role of antiemetic therapy with neurokinin-1 (NK1) receptor antagonists (RAs) in nonanthracycline and cyclophosphamide (AC)-based moderately emetogenic chemotherapy (MEC) regimens, this study evaluated single-dose intravenous (i.v.) fosaprepitant for the prevention of chemotherapy-induced nausea and vomiting (CINV) associated with non-AC MEC. PATIENTS AND METHODS I...

Previous studies using transgenic mice showed that Wnt-1 expression in mammary gland causes alveolar hyperplasias which resemble mammary glands of pregnant mice.

Our laboratory has developed virtually identical techniques for the isolation and culture of mammary epithelial cells (MEC) from rats and humans. In a cell-mediated mutagenesis assay, rat MEC activated 7,12-dimethylbenz(a)anthracene (DMBA) but not benzo(a)pyrene [B(a)P] to mutagenic forms, and the opposite pattern was found with human MEC. These species-specific patterns were not readily explai...

Grid cells in the medial entorhinal cortex (MEC) are part of an environment-independent spatial coordinate system. To determine how information about location, direction, and distance is integrated in the grid-cell network, we recorded from each principal cell layer of MEC in rats that explored two-dimensional environments. Whereas layer II was predominated by grid cells, grid cells colocalized...

The K + scattering on the lightest nuclei, d, 3 He and 4 He is studied in the framework of multiple scattering theory. Effects from MEC tied to the K + N → KN π reaction are evaluated. We found that at momentum transfers Q 2 < 0.5 (GeV/c) 2 contributions from MEC are much smaller than kaon rescattering corrections. This makes the conventional multiple scattering picture a reliable tool to study...

Primary cutaneous mucoepidermoid carcinoma (MEC) is a rare disease entity. Only around 20 cases have been reported so far. Herein, we present two cases for better understanding of the condition: A 74-year-old lady with a low-grade primary cutaneous MEC at her right external auditory ear canal was treated with surgical resection and adjuvant radiotherapy. The patient developed recurrence five mo...

It was formerly demonstrated that PL retard and Choi accelerates the formation of tumours induced by M e C 2. This retardation respectively acceleration, however, never surpassed a period of somewhat more than four weeks. The question, then, arose why PL are only capable to retard temporarily and not to pre­ vent, i. e. retard permanently, the formation of tu­ mours. It was presumed that the ad...
