    Comparison of the antiviral action of different human interferons against DNA and RNA viruses (1984)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Biology
    Notes: Abstract Five different interferon preparations were compared for their antiviral activity against Herpes simplex virus type 1 (HSV-1) and several RNA viruses. The interferons used were: interferon α from human buffy coats, interferon β from human fibroblasts, interferon γ from human lymphocytes after stimulation with phytohemagglutinin (PHA), lymphoblastoid interferon from Namalva cells IFN-α (Ly) and cloned α2 interferon produced by Escherichia coli containing the human gene for interferon α2. All preparations were able to protect monolayers of HeLa cells against HSV-1 infection when low multiplicities were used. The five IFN preparations were also tested against encephalomyocarditis (EMC) virus, poliovirus and vesicular stomatitis virus (VSV).

    Do cells treated with human interferon survive virus infection? (1983)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 20 (1983), S. 0

    Topics: Biology
    Notes: Abstract HeLa cells pretreated with human lympho-blastoid interferon (Hu IFN-α (Ly)), at concentrations up to 100 IU / ml and infected with moderate multiplicities of encephalomyocarditis (EMC) virus (10 PFU / cell) died 1 or 2 days after infection. However, if cells were repeatedly treated with high doses of IFN (800 IU / ml) they survived infection by EMC virus for at least a month. Cells survived Semliki Forest virus (SFV) infection when even lower IFN concentrations were used. By contrast infection of IFN-treated HeLa cells with other RNA-containing viruses, such as poliovirus, vesicular stomatitis virus (VSV), Newcastle disease virus (NDV) and reovirus type 3 resulted in cell death. Similarly, infection with a number of DNA-containing viruses such as adenovirus type 5, Herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and vaccinia virus killed cells. The results are discussed in the light of different models for the molecular mechanism of action of interferon.

    Effect of Calcium and Magnesium on the Antibacterial Activity of Phenolic Antioxidants Against Staphylococcus aureus A100 (1984)

    Notes: Butylated hydroxyanisole (BHA) at 150 ppm, and tertiary butylhydroquinone (TBHQ) at 100 ppm, were tested against Staphylococcus aureus A100 in the presence of 50 and 100 mM Ca2+ or Mg2+. The inhibitory activity of BHA was increased by the presence of Ca2+ but not Mg2+ in the suspending buffer. An increase in Ca2+ concentration did not cause additional increase in the activity of this compound. With TBHQ, there was no apparent increase in antibacterial activity by the presence of either Ca2+ or Mg2+.

    Development, Evaluation and Industrial Production of a Powdered Soy-Oats Infant Formula Using a Low-Cost Extruder (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 46 (1981), S. 0

    Notes: A low cost powdered infant formula made from soybeans, oats and sucrose, fortified with methionine, vitamins and minerals, has been developed. A dry process for making the formula, which employs a low-cost Brady extruder, has also been developed. The resulting product is of good microbiological quality and disperses readily in water to give a milk-like suspension of satisfactory stability to settling. The essential amino acid pattern of the formula, its PER and NPU values, nitrogen balance data with infants, proximal chemical analysis, calorie distribution and low level of trypsin inhibitor indicate it to be adequate for feeding infants 3 months or older. Clinical trials with infants also showed that the formula was well accepted and tolerated, and produced adequate weight gain. Retail prices of the product, packed in cans and polyethylene bags, are appreciably lower than those of comparable cow's milk and other soya-based infant formulas available in the market. The product is currently being manufactured and sold in several parts of Mexico.

    Effect of Corn Oil and Casein on the Antimicrobial Activity of Phenolic Antioxidants (1983)

    Notes: Several inhibitory concentrations of butylated hydroxyanisole (BHA) and tertiary butylhydroquinone (TBHQ) were tested against five microorganisms in the presence of 0, 1.5, 3.0 and 4.5% (v/v) of a lipid, corn oil, or 0, 3, 6 and 9% (w/v) of a protein, casein. In all cases, casein depressed, but did not abolish, the antimicrobial activity of BHA. However, corn oil virtually eliminated the antimicrobial properties of lethal doses of BHA. In contrast, TBHQ was affected much less by the food components than BHA, retaining considerable antimicrobial activity in most cases except with Staphylococcus aureus.

    Entamoeba histolytica: Collagenolytic Activity and Virulence (1984)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 31 (1984), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Several axenic strains of pathogenic and nonpathogenic Entamoeba histolytica were tested for their capacity to digest native radioactive type I collagen gels and to produce liver abscesses when injected into the liver of newborn hamsters. The results demonstrate that the pathogenic strains of amebas (HM1:IMSS, HM3:IMSS, HM38:IMSS, and HK9) have a collagenolytic activity that closely correlates with their in vivo capacity to produce liver lesions. The nonpathogenic isolate (Laredo) did not show collagenolytic activity and failed to produce lesions in the liver of newborn hamsters. The results also demonstrate that type I collagen obtained from rodents and cats is degraded less by amebic collagenase than is bovine collagen, which is similar to human collagen. These findings suggest that species susceptibility to invasive infection may depend, among other factors, on the characteristics of the extracellular components of host tissues.

    Chemical and Nutritional Studies on Mesquite Beans (Prosopis juliflora) (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0

    ISSN: 1750-3841

    Notes: Mesquite beans (Prosopis juliflora) consisted of pericarp, hulls and kernels. With the exception of kernels, composition of beans and their fractions were protein, 10–15%; fat, 2–3%; crude fiber, 20–30%; sucrose, 21%; reducing sugars, 2–6%. Kernels contained 38% protein, 3% fat and 9% crude fiber. Bean trypsin inhibitor content was 1.4 TIU/mg. Bean protein isoelectric point was pH 5. Mesquite protein concentrate and isolate were prepared, however, by increasing solubility at the extraction pH (pH 10) with NaCl and decreasing it at the isoelectric point with (NH4)2SO4. First and second limiting amino acids for bean protein were threonine and isoleucine, respectively; the protein was high in total sulfur amino acids and tryptophan. Corrected PER was 1.4.
