The range of inositol phosphates and inositol phospholipids present in three filamentous fungi, Neurospora crassa, Fusarium graminearum and Phanerochaete chrysosporium has been investigated by HPLC analysis. The profiles obtained demonstrate that two isomers of phosphatidyl inositol monophosphate are present, and that an apparent complexity in the number of(More)
The hematopoietic cell lines HL-60 and THP-1 were challenged with hepatitis B virus (HBV) in vitro to study interactions between the virus and host cell. Exposure to HBV suppressed the ability of HL-60 cells to differentiate into granulocytes after treatment with retinoic acid (RA) or dimethyl sulfoxide (DMSO), and RA-induced activation of the monocytic(More)
AIMS/METHODS Four assays for measuring HBV-DNA quantitatively have been compared with regard to sensitivity, precision and linearity. The methods were 125I-labelled solution hybridisation assay (liquid hybridisation, Abbott), an ELISA-based chemiluminescent RNA-DNA hybrid assay (RNA-DNA, Digene), a chemiluminescent branching oligonucleotide assay (bDNA,(More)
Phosphatidylinositol 4,5-bisphosphate specific phospholipase C has been detected in a membrane preparation fromPharbitis nil cotyledons. The enzyme has a pH optimum of 6.8 and activated by calcium ions, deoxycholate, phosphatidylinositol and phosphatidylethanolamine. The enzyme is inhibited to varying degrees by Tween 20, Triton XI00, zinc, copper, cobalt(More)
A sample of RR Lyrae (RRL) variables from the Southern Edgeworth-Kuiper Belt Object survey in regions overlapping the expected position of debris from the interaction of the Sagittarius (Sgr) dwarf galaxy with the Milky Way (RA ∼ 20 and 21.5 h; distance = 16– 21 kpc) has been followed up spectroscopically and photometrically. The 21 photometrically(More)
We map the three dimensional extent of the Virgo Over-density by combining distance information from RR Lyrae variables and projected spatial information from SEKBO (Keller et al. 2008) and Sloan Digital Sky Survey (SDSS) DR6 photometry. The Virgo Over-density is seen to comprise two filaments 14.5◦ × 3◦ and 10◦ × 3◦ and a circular structure 3◦ in diameter.(More)
We describe the establishment and characterization of a novel hepatoma cell line. This cell line, designated RBHF-1, was established from a hepatocellular carcinoma of a 67-yr-old man with a history of genetic hemochromatosis. At this writing, the cells have been maintained in RPMI-1640 tissue-culture medium and fetal calf serum without any additional(More)
Suspension cultures of bone marrow cells (BMC) were challenged with hepatitis B virus (HBV) to study interactions between the virus and the nonadherent and adherent BMC populations. Virus-challenged BMC developed an adherent stromal layer that differed in cellular composition from that of mock-infected cultures, showing a threefold increase in cells of the(More)
