    Notes: Abstract Survival rates, renal function, and histopathology were evaluated in 49 prospectively followed patients transplanted under 5 years of age at our center. Most patients (84 %) suffered from congenital nephrosis of the Finnish type. Triple immunosuppression with cyclosporine administered in three daily doses to pre-school children was used. Patient survival 7 years after transplantation was 98 % and graft survival 88 %. All graft losses were due to post-transplantation nephrosis. The proportion of pathological findings in the follow-up biopsies did not change substantially with time. Five years after transplantation, 47 % showed a normal histology and after 7 years this rose to 67 %. Mean glomerular filtration rate (GFR) was 68 and 55 ml min per 1.73 m2 5 years and 7 years, respectively, after transplantation. The decline in GFR with time was significant. We conclude that good long-term results can be achieved with individually tailored triple immunosuppression in the youngest age group, even with cadaveric donors.

    Description / Table of Contents: Abstract Ъыло найдено, что гндрат молибдата никеля является эффективным прекурзором в гидродесульфуризации тиофена. Прокаливание гидрата при 300°C и пресульфидирование с помощью H2S представляет собой обработку, благоприятствующую повышению активности.
    Notes: Abstract Nickel molybdate hydrate has been found to be an effective precursor catalyst for the hydrodesulfurization of thiophene. Calcination of the hydrate at 300°C and presulfidation with H2S are favorable treatments for higher activity.

    Description / Table of Contents: Abstract Распределение кислотной силы в системах окислов Mo−Al−Si и Ni−Mo−Al было определено с помощью зависимости, дающей величины рК из количества адсорбированного аммиака. Молибден вызывает гомогенизацию в распределнии кислотной силы алюмихия и гетерогенизаци ю на окислах кремния и алюминия, в то время как никель нейтрализует сильные кислотные центры, присущие молибдену.
    Notes: Abstract Acid strength distributions of Mo−Al−Si and Ni−Mo−Al oxide systems have been found by means of a relationship that gives pKa values from amounts of ammonia adsorption. Molybdenum is suggested to cause a homogenization in the acid strength distribution of alumina but a heterogenization in silicaalumina, whereas nickel is found to neutralize strong acid sites inherent to molybdenum.

    Notes: Summary Gold sodium thiosulphate (GSTS) In patch test series commonly yields positive reactions. In this study of dental patients, the clinical relevance of these positive reactions, the suitability of gold compounds as patch test materials, and value of the lymphocyte proliferation test in gold contact allergy, were evaluated. The frequency of positive patch test reactions to GSTS was 12·4% in the dental series. Fifty-two patients, only two of whom were male, were studied. Thirteen (25%) had had symptoms from jewellery or dental restorations. However, in most cases gold allergy was subclinical. A 10% aqueous solution of gold sodium thiomalate (GSTM) was almost as good as 0·5% GSTS in petrolatum as a marker of gold contact allergy, but 0·001% potassium dicyanoaurate (PDCA) yielded a high percentage of false-negative results. Seventy-three per cent of the subjects with positive patch tests to GSTS responded to gold compounds in vitro in the lymphocyte proliferation test, whereas 13 controls without gold contact sensitivity were negative. Consistent results in skin and lymphocyte proliferation tests provide support for the concept that gold salt-induced‘allergic-like' reactions are truly allergic in nature.

    Notes: Abstract We report the results of 41 consecutive renal transplantations performed on 39 children (median age 2.7 years). Twenty-six recipients were less than 5 years old. Twenty-one recipients (13 under the age of 5 years) received cadaver (CAD) grafts. All grafts except 2 were from adult donors and were placed extraperitoneally. Patients were on triple immunosuppression (cyclosporine plus azathioprine plus methylprednisolone). Mean followup time was 2.3 years. No vascular and only one ureteral complication was seen. Acute tubular necrosis occurred in 3 patients (7.3%). No grafts were lost due to acute rejection. Three-year patient survival and 1-year graft survival were 100%. The overall 3-year actuarial graft survival was 86%. Three-year survival of grafts from living-related donors (LRD) was 92% and that of CAD grafts 75%. In recipients younger than 5 years, 3-year LRD graft survival was 89% and CAD graft survival 73%. No significant differences in graft survival between recipients of different age groups or between LRD and CAD grafts were found. We conclude that results of renal transplantation in children under 5 years of age are comparable to those of older children, even using CAD grafts, when adult donors and triple immunosuppression are used.

    Notes: Effects of rheological parameters of polyolefin suspension were studied to better understand stirred tank polymerization reactors and their engineering principles. Experimental results have been fitted into a quadratic model. Consistency index and behavior index have been determined as functions of solids concentration, temperature, and particle size.

    Notes: Abstract A Raney copper film obtained from a Cu-Al alloy deposited by evaporation on a steel plate was found to behave as a copper on alumina catalyst. Contrary to what is found when the Raney is prepared directly from the alloy, prereduction with CO caused an increase in the catalytic activity for CO oxidation.

    Notes: Abstract The hydrodenitrogenation (HDN) of pyridine over activated carbon-supported Mo and NiMo sulfided catalysts was studied. Without H2S in the feed the catalysts showed a high conversion of pyridine and of piperidine to C5 hydrocarbons at the beginning of reaction, followed by a strong deactivation. A large increase in the conversion of pyridine was observed when H2S was added to the feed at H2S/H2⩾0.006. The conversion of piperidine to C5 hydrocarbons was enhanced by H2S and it increased as the H2S pressure increases up to H2S/H2⩾0.006. The promotion effect of Ni was operative only when H2S was present and it increased with the H2S/H2 ratio. Without H2S, the degree of surface oxidation of the support affected the deactivation of the catalysts. When H2S was added to the feed, the conversion of pyridine was stable and independent of the acid treatment of the support. A more oxidized support enhanced the C-N bond breaking reaction.
