    Ferritin synthesis by human T lymphocytes (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-08-29
    Description: Mononuclear cells from peripheral blood of normal humans, unselected spleen cells from patients with Hodgkin's disease, and selected T and non-T lymphoid cells from normal peripheral blood and from the spleens of Hodgkin's disease patients were examined for de novo synthesis and secretion of ferritin. After precipitation of labeled lysates and supernatants from unseparated and selected T cells with antiserum to human liver ferritin, two bands were visible on sodium dodecyl sulfate-polyacrylimide gel analysis. The two bands were detected in molecular weight regions 19,000 and 21,000, which are thought to represent the L and H subunits of the ferritin molecule, respectively. The slower band (subunit H) was more radioactive than the faster band (subunit L). The H subunit is found in greater amounts in the serum of some tumor patients, but its cellular origin has not been established. The present findings indicate that cells of the immune system contribute to the synthesis and secretion of a ferritin molecule with a high proportion of H subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dorner, M H -- Silverstone, A -- Nishiya, K -- de Sostoa, A -- Munn, G -- de Sousa, M -- New York, N.Y. -- Science. 1980 Aug 29;209(4460):1019-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6967622" target="_blank"〉PubMed〈/a〉

    Use of the upflow sludge blanket (USB) reactor concept for biological wastewater treatment, especially for anaerobic treatment (1980)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: In recent years considerable effort has been made in the Netherlands toward the development of a more sophisticated anaerobic treatment process, suitable for treating low a strength wastes and for applications at liquid detention times of 3-4 hr. The efforts have resulted in new type of upflow anaerobic sludge blanket (UASB) process, which in recent 6 m3 pilot-plant experiments has shown to be capable of handling organic space loads of 15-40 kg chemical oxygen demand (COD)·m-3/day at 3-8 hr liquid detention times. In the first 200 m3 full-scale plant of the UASB concept, organic space loadings of up to 16 kg COD·m-3/day could be treated satisfactorily at a detention times of 4 hr, using sugar beet waste as feed. The main results obtained with the process in the laboratory as well as in 6 m3 pilot plant and 200 m3 full-scale experiments are presented and evaluated in this paper. Special attention is given to the main operating characteristics of the UASB reactor concept. Moreover, some preliminary results are presented of laboratory experiments concerning the use of the USB reactor concept for denitrification as well as for the acid formation step in anaerobic treatment. For both purposes the process looks feasible because very satisfactory results with respect to denitrification and acid formation can be achieved at very high hydraulic loads (12 day-1) and high organic loading rates, i.e., 20 kg COD·m-3/day in the denitrification and 60-80 kg COD·m-3/day in the acid formation experiments.

    Saccharification of bamboo carbohydrates for the production of ethanol (1983)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 25 (1983), S. 1071-1082

    Notes: Bamboo carbohydrates were hydrolyzed with commercial amylases and a mixture of fungal culture broths containing cellulolytic and hemicellulolytic enzymes. The effects of cooking temperature and the size of fiber particles were also investigated. It was found that the higher the cooking temperature, the higher the rate of sugar formation and the lower the viscosity of the slurry. Additions of cellulose and hemicellulose digesting enzymes increased the sugar yield and decreased the viscosity of both the cooked and noncooked slurries. A smaller size of particle appeared to favor the average saccharification rate. Although glucose, xylose, and cellobiose were present in the hydrolysates, only 50% of the total carbohydrate was digested, and 78.9% of this was converted to reducing sugars. The alcohol efficiency for the fermentation of cooked and noncooked mashes by Saccharomyces was about 85%.

    A quantitative description of the growth of Saccharomyces cerevisiae CBS 426 on a mixed substrate of glucose and ethanol (1980)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Saccharomyces cerevisiae CBS 426 was grown aerobically in continuous culture with a mixture of glucose and ethanol as the carbon source. The flows of biomass, glucose, ethanol, oxygen, and carbon dioxide were measured. A model for growth with two substrates was derived. Application of this model to the above-mentioned system yielded values for YATP and P/O. The joint confidence regions for these parameters were calculated. The relevance to industrial production of bakers' yeast is discussed.

    Platelet thromboxane synthetase inhibitors with low doses of aspirin: possible resolution of the "aspirin dilemma" (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-29
    Description: Selective pharmacological inhibition of thromboxane A2 synthesis did not prevent arachidonate-induced aggregation of human platelets in vitro. Prevention was instead achieved by a combination of thromboxane A2 inhibitors with low concentrations of aspirin. The latter partially reduced the proaggregatory cyclooxygenase products that accumulated when thromboxane A2 synthesis was blocked. The aspirin concentrations did not affect per se either platelet aggregation or prostacyclin synthesis in cultured human endothelial cells. The combination of thromboxane synthetase inhibitors with low doses of aspirin may offer greater antithrombotic potential than either drug alone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bertele, V -- Falanga, A -- Tomasiak, M -- Dejana, E -- Cerletti, C -- de Gaetano, G -- New York, N.Y. -- Science. 1983 Apr 29;220(4596):517-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6682245" target="_blank"〉PubMed〈/a〉

    Mechanical action of the intercostal muscles on the ribs (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-01
    Description: The external and internal interosseous intercostal muscles were separately stimulated at end-expiratory lung volume in anesthetized dogs. These muscles were all found to elevate the ribs into which they insert. By attaching weights to the ribs, it was determined that the nonlinear compliance of the ribs was responsible for this phenomenon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Troyer, A -- Kelly, S -- Zin, W A -- New York, N.Y. -- Science. 1983 Apr 1;220(4592):87-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6828883" target="_blank"〉PubMed〈/a〉

    Fibronectin binds to some bacteria but does not promote their uptake by phagocytic cells (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-08
    Description: The involvement of plasma fibronectin in phagocytosis of bacteria was investigated by testing the binding of fibronectin to several species of bacteria and by evaluating the ability of fibronectin to promote binding and endocytosis of two species of these bacteria by phagocytic cells. Fibronectin binds non-covalently to Gram-positive and Gram-negative bacteria and to yeast but did not appear to be necessary or sufficient for uptake of Staphylococcus aureus and Salmonella typhimurium by several different phagocytic cell types.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van de Water, L -- Destree, A T -- Hynes, R O -- R01CA17007/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1983 Apr 8;220(4593):201-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6338594" target="_blank"〉PubMed〈/a〉
