In experiments on the accumulation and elimination of virus particles by Pacific oysters (Crassostrea gigas), an Escherichia coli C2 bacteriophage was used as a virus model. It became necessary to quantitate low concentrations of phage present in samples of seawater, oyster shell liquor, and oyster meats and feces. The agar overlay phage plaque assay is subject to the same limitations with rega...

Removal of the mRNA 5' cap is an important step in the regulation of mRNA stability. mRNAs are degraded by at least two distinct exonucleolytic decay pathways, one from the 5' end, and the second from the 3' end. Two major cellular decapping enzymes have been identified, and each primarily functions in one of the two decay pathways. The Dcp2 decapping enzyme utilizes capped mRNA as substrate an...

Regulation of the pointed, or slow-growing, end of actin filaments is essential to the regulation of filament length. The purpose of this study is to investigate the role of skeletal muscle tropomyosin (TM) in regulating pointed end assembly and disassembly in vitro. The effects of TM upon assembly and disassembly of actin monomers from the pointed filament end were measured using pyrenyl-actin...

introduction: there are suspended fungal spores in the air and in the nasal mucosa of adults, especially in areas with a humid climate. several studies have revealed the role of fungi in the pathogenesis of chronic rhinosinusitis (crs) in recent years but it is a topic of controversy, especially in regions with low humidity. the aim of this study was to evaluate the prevalence of fungal species...

The separation and characterization of octylphenol ethoxylate surfactants were carried out by reversed-phase high-performance liquid chromatography on branched fluorinated silica gel columns. For Triton X-100, simultaneous separation of octylphenol ethoxylate oligomers, positional isomers of octylphenyl group and butylphenol ethoxylate oligomers was achieved. These oligomers were completely sep...

We report on the real-time structure formation and growth of two thiophene-based organic semiconductors, $5,{5}^{\ensuremath{'}}$-bis(naphth-2-yl)-$2,{2}^{\ensuremath{'}}$-bi- $5,{5}^{\ensuremath{'}\ensuremath{'}}$-bis(naphth-2-yl)-$2,{2}^{\ensuremath{'}}$:${5}^{\ensuremath{'}},{2}^{\ensuremath{'}\ensuremath{'}}$-terthiophene (NaT2 NaT3), studied in situ during vacuum deposition by grazing-inci...
