Researchers from Masaryk University in Brno, Czech Republic, have identified the eIF4F translation initiation complex as a key player in melanoma resistance to BRAF and MEK inhibitors. Their study reveals that eIF4F negatively regulates the RAS/RAF/MEK/ERK MAPK signaling pathway in melanoma cells with BRAF or NRAS mutations. By disrupting this feedback control mechanism, small-molecule eIF4F inhibitors could potentially lead to hyperactivation of ERK signaling in melanomas with these mutations. This research, supported by various funding sources, sheds light on the critical role of eIF4F in controlling ERK signaling intensity in melanoma cells. [Extracted from the article]

A recent study conducted by Masaryk University in Brno, Czech Republic, explored the potential of fish as a source of infection with the nematode Angiostrongylus cantonensis, which causes human eosinophilic meningitis. The research found that while the larvae of A. cantonensis can survive and remain infective in fish for a short period, they typically die within the first few days post-infection. This suggests that fish may not be significant long-term hosts for A. cantonensis but may play a temporary role in its transmission to mammals and birds, including humans. The study underscores the importance of understanding aquatic host interactions in the epidemiology of this zoonotic foodborne pathogen. [Extracted from the article]

The researchers concluded that a negative CTP result necessitates consideration of both stroke and non-stroke diagnoses. [Extracted from the article]

The relations between Leoš Janáček and German musical culture -- either in the Czech Lands or abroad -- deserve attention for many reasons. As part of the ongoing research on the early Janáček reception (1872--1888), we have focused on the attitudes of German musical critics towards Janáček. The German, in particular the Brno-based, press played an essential role in the process in question, this being a fact which nobody has taken into account yet. The suppression of national aspects fundamentally distinguished the way Brno-based German critics wrote about the young Janáček from the way Czech press in Brno, Prague and elsewhere reported on him. While the Czech reception of Janáček was nationalistic from the very beginning, the reception of Janáček by the Brno Germans suggests that the Liberal concept of German music, local and regional patriotism, and, of course, the music itself can not only disturb but even transcend national borders. But only to a certain extent. In other words, it seems that German critics tried to adopt those aspects of Janáček and his artistic activities which corresponded to their concept of Germanness (Deutschtum) and, in contrast, tried to eliminate aspects of the difference.
