Humanin (HN) is a newly discovered 24-amino acid peptide, which may suppress neuronal cell death. HN cDNA includes the open reading frame (HN-ORF) of 75 bases, located 950 bases downstream of the 5' end of the HN cDNA. It was demonstrated that HN cDNA is 99% identical with mitochondrial DNA (mtDNA) sequence. HN homologues have been identified as expressed sequence tags (ESTs) in rat and nematod...

Complementary DNA clones to 90% of the Newcastle disease virus (NDV) genome have been produced and mapped. These clones cover the entire HN, F and M genes, most if not all of the L gene and parts of the NP and P genes. The map of overlapping clones gives the gene order 3'-NP-P-M-F-HN-L-5' for NDV, identical to the gene order of Sendai virus, on the assumption that the NP gene of NDV is at the 3...

A simple and robust method using high-performance liquid chromatography with UV detection was developed and validated for the determination of six pyrrole-imidazole (PI) polyamides (HN.49, TGF-β1f, TGF-β1t, HN.50f, HN.50t, and LOX-1) in rat plasma. After the plasma proteins were precipitated with methanol containing phenacetin as an internal standard, the analytes were separated on a Luna C18 (...

A labelling of the n-dimensional hypercube Hn is a mapping that assigns value 0 or 1 to each edge of Hn. A labelling is antipodal if antipodal edges of Hn get assigned different values. It has been conjectured that if Hn, n ≥ 2, is given a labelling that is antipodal, then there exists a pair of antipodal vertices joined by a monochromatic path. This conjecture has been verified by hand for n ≤...

For paramyxoviruses, entry requires a receptor-binding protein (hemagglutinin-neuraminidase [HN], H, or G) and a fusion protein (F). Like other class I viral fusion proteins, F is expressed as a prefusion metastable protein that undergoes a refolding event to induce fusion. HN binding to its receptor triggers F refolding by an unknown mechanism. HN may serve as a clamp that stabilizes F in its ...

Head and neck (HN) sarcomas constitute about 5-10% of all sarcomas and only 1% of all HN tumor types. According to the limited work published to date about HN sarcomas, histological subtype is a significant prognostic factor in addition to tumor size, Histological Grade (HG), depth of invasion, HN location and surgical resection margin status [1]. Fibrosarcoma, undifferentiated pleomorphic sarc...

The fusion (F) and hemagglutinin-neuraminidase (HN) glycoproteins of the paramyxovirus simian virus 5 (SV5) were expressed individually or coexpressed in CV-1 cells by using SV40-based vectors and recombinant vaccinia viruses. The extent of detectable fusion in a syncytium formation assay was found to be affected by the expression system used. In addition, when HN was coexpressed with F, it was...

A cDNA library was constructed in lambda gt10 using mRNA purified from cells infected with parainfluenza virus type 2 (PIV2). Virus-specific clones were identified by screening the library with 32P-labelled cDNA probes made from randomly primed vRNA. Clones containing the haemagglutinin-neuraminidase (HN) gene were identified by sequence comparisons with known parainfluenza virus HN gene sequen...
