This study calculated the spectrum entropy (SE), approximate entropy (ApEn), and Lem-Ziv complexity (LZC) of sleeping EEG signals of eight healthy adults. The statistical results show that all the three nonlinear features can clearly reflect sleeping stage. Among them, the SE is easy to calculate and traces varying sleeping periods fairly and consistently, while the ApEn performs even better but is relatively complicated.

Localization of RNA replication to intracellular membranes is a universal feature of positive-strand RNA viruses. The betanodavirus greasy grouper (Epinephelus tauvina) nervous necrosis virus (GGNNV) is a positive-RNA virus with one of the smallest genomes among RNA viruses replicating in fish cells. To understand the localization of GGNNV replication complexes, we generated polyclonal antisera against protein A, the GGNNV RNA-dependent RNA polymerase.

Betanodaviruses, members of the Nodaviridae family, are the causative agents of viral nervous necrosis in fish and infection by which cause high mortality in larvae and juveniles in a wide range of marine fish species in Asia, Europe, Australia, Martinique, and Tahit. Greasy grouper (Epinephelus tauvina) nervous necrosis viruses (GGNNV) were investigated for their apoptotic activity in culture cells. GGNNV infection of sea bass (SB) cells appeared to induce a typical cytopathic effect (CPE), i.

Betanodavirus greasy grouper (Epinephelus tauvina) nervous necrosis viruses (GGNNV) protein alpha, a virus capsid protein, was detected in both nucleolus and cytoplasm of infected cells of Asian sea bass (SB) and transfected cells of SB and Cos-7 with pcDNA3.1/RNA2. To study its subcellular localization, ORF of protein alpha with 338 aa was fused with enhanced green fluorescent protein (EGFP) gene and was detected in transfected cells in the absence of other viral proteins.

CD20 is a specific antigen expressed on normal and neoplastic B cells exclusively. Recent researches showed that in B cell leukemia, CD20 was over-expressed. Therefore monoclonal antibody (McAb) to CD20 may be of clinical value in diagnosis and treatment of some leukemias and lymphomas.
