Abstmcr-Most second-order RC active filters show II marked dependence on tbe gdn-bnndwidtb product (GB) of operational aniplifietx (OA’s) when the w, to be reali& is greater than 1 percent of GB and Q> 10. Here designs are given that are. virtually independent of OA’s when we<O.Ol GB and Q< 10. Even for w0=0.05 GB and Q=lO, the center frequency shift due to OA’s is less than 0.1 percent. ‘Ihis ...

s–Healthcare is important to every country, including developing country like Malaysia in providing a good life. Therefore, the Malaysian Government had taken several iniatiatives to enhance healthcare sector. One of the initiatives is bringing the Information System into Malaysian Public Hospitals. This is similar to enhance the ICT tools within Malaysia in achieving 2020 Vision to make Malays...

Serum IgG or, predominantly, IgM antibody binding to electrophoretically separated normal platelet membrane protein antigens were detected by immunoblotting in five children with thrombocytopenia associated with varicella. Glycoproteins GPIb, GPIIb, GPIIIa, and other 25-260 kilodalton (kDa) proteins were identified as target antigens, suggesting a transient autoimmune mechanism causing the thro...

Evidence is presented to support the contention that IgM demonstrable by surface immunofluorescent staining on H-2-activated T cells represents specifically adsorbed B-cell-derived alloantibody. T cells activated to H-2 determinants expressed surface IgM only when the progenitor cell populations contained B lymphocytes. IgM was not detected on T cells activated to determinants which fail to sti...

The doctrine of the astrological aspec/s, or distances between two celestial objecls 5uch as planets is sometimes defined in terms of these objects emanating rays in ccrtain direclions of astrological significance 2 • Tr aue of tbese rays reaches an objccl al a particular angular distance, the two objects could be in conjunction (00), sextile (60°), quartile (90°), trine (120°) or opposition (I...

CBA/N mice, which possess an X-linked immunodeficiency (xid), produce a convincing antibody response to lipopolysaccharide derived from Escherichia coli 0113 (LPS 0113), a thymus-independent antigen. The antibody response produced was shown to be specific for the O-polysaccharide moiety of LPS 0113, rather than lipid A or lipid-A-associated protein. The relevance of this finding to the nature o...

The idiotypic determinants on IgM rheumatoid factor (RF) from a single family have been analyzed. Rabbit Fab'2 antiidiotypic antibody was prepared against purified IgM-RF from a patient with rheumatoid arthritis. As measured by radioimmunoassay, the antiidiotype reacted with at least 90% of the patient's RF, but not with non-RF immunoglobulins from the same serum, nor with 10 of 11 polyclonal a...

THERE iS little doubt that most doctors regard the outlook for their asthmatic patients with pessimism. Often the available literature has been sifted and the recommended treatments faithfully carried out, and yet the patient is no better. Small wonder if the busy practitioner, surrounded with patients for whom he reallv can do something, pushes aside the idea of further attempts at curative tr...
