UNLABELLED The nucleoprotein (NP) of influenza viruses is a multifunctional protein with essential roles throughout viral replication. Despite influenza A and B viruses belonging to separate genera of the Orthomyxoviridae family, their NP proteins share a relatively high level of sequence conservation. However, NP of influenza B viruses (BNP) contains an evolutionarily conserved N-terminal 50-a...

A rare case of a Wilms tumor with intracardiac neoplastic extension is presented. The good prognosis of even extensive nephroblastoma is the reason for attempting a radical surgical approach to patients with intracardiac tumor thrombus. The exact preoperative delineation of the intracasal tumor extension is essential for a safe and successful operation. Ultrasonography in combination with echoc...

It is well-known that a countably injective module is Σ-injective. In Proc. Amer. Math. Soc. 316, 10 (2008), 3461-3466, Beidar, Jain and Srivastava extended it and showed that an injective module M is Σ-injective if and only if each essential extension of M(א0) is a direct sum of injective modules. This paper extends and simplifies this result further and shows that an injective module M is Σ-i...
