1. Glycopeptides containing mannose were extracted from isolated yeast cell walls by ethylenediamine and purified by treatment with Pronase and fractionation on a Sephadex column. 2. A glycopeptide that appeared homogeneous on electrophoresis and ultracentrifugation had a molecular weight of 76000, and contained a high-molecular-weight mannan and approx. 4% of amino acids. 3. The amino acid com...
Adaptive Filtering is an important concept in the field of signal processing and has numerous applications in fields such as speech processing and communications. An Adaptive filter is a filter that self-adjusts its transfer function according to an optimizing algorithm. Because of the complexity of the optimizing algorithms, most adaptive filters are digital filters that perform digital signal...
The balance of tissue-type plasminogen activator (t-PA) production and degradation determines its concentration in blood and tissues. Disturbance of this balance may result in either increased or decreased proteolysis. In the present study, we identified the receptor systems involved in the degradation of t-PA by human monocytes/macrophages in culture. Monocytes were cultured and became macroph...
Concentrations of arabinitol, mannose, and mannan in serum have independently been reported to be elevated in patients with invasive candidiasis. These three marker substances were compared in a rabbit model. Twelve rabbits, immunosuppressed with cortisone, were infected intravenously with Candida albicans 3181A. Six uninfected control animals also received cortisone, and four rabbits were neit...
We estimate the loading rate in southern California and the change in stress induced by a transient slip event across the San Andreas fault (SAF) system in central California, using a model of static fatigue. We analyze temporal properties of aftershocks in order to determine the time delay before the onset of the power law aftershock decay rate. In creep-slip and stick-slip zones, we show that...
A simple method was devised for negative-stain transmission electron microscopy of brain infected with the agent of scrapie. Brains of infected hamsters contained large masses of tubulofilamentous structures with irregular fuzzy surfaces. Brains of mice infected with Creutzfeldt-Jakob disease agent contained similar tubulofilaments in smaller numbers. The abnormal tubulofilaments resembled but ...
Removal of blood group antibodies against the donor organ prior to ABO-incompatible transplantation can prevent episodes of hyperacute rejection. We are developing a specific antibody filter (SAF) device consisting of immobilized synthetic Atrisaccharide antigens conjugated to polyacrylamide (Atri-PAA) to selectively remove anti-A antibodies directly from whole blood. In this study, we evaluate...
The dehydration-rehydration vesicle (DRV) method was used to encapsulate hepatitis B surface antigen (HBsAg) in phosphatidylcholine (PC) and distearoyl phosphatidylcholine (DSPC) liposomes giving entrapment values of 31.7% and 33.1% respectively. A comparison of antibody levels, as determined by ELISA, in the primary and secondary immune responses in mice immunized twice with 1 microgram HBsAg ...
The aim of this study was to evaluate the efficiencies of the self-adjusting file (SAF) system, passive ultrasonic irrigation (PUI), and conventional irrigation (CI) in removing calcium hydroxide (CH) from root canals. Fifty-one mandibular premolars were used. After root canals were instrumented and filled with a CH paste, 45 teeth were randomly assigned to three experimental groups according t...
As storage system runs an increasing variety of workload, there may be many file requests do not dispatch for a long time. The web clients who wait a long time will leave away. This paper presents a novel non-partitioning file assignment strategy called Static Approximate Fairness algorithm (SAF) in parallel I/O system. The SAF algorithm aims at obtaining approximate mean waiting time for disk ...
