    Notes: The botanical composition, intake and digestibility of the diet consumed by 1-year-old weaner sheep grazing a native white grass plant community in the Falkland Islands was measured in five periods between June 1998 and March 1999. Five different sheep were used in each period. Two methods were used for estimating the botanical composition of the diet: plant cuticle patterns in the faeces of the sheep and the patterns of concentrations of n-alkanes in the faeces of sheep. These methods were used to predict the concentrations of C32- and C33-alkanes in the herbage to allow the estimation of herbage intake and digestibility using the n-alkane technique. It was concluded that the n-alkane technique gave more accurate estimates of diet composition based on the comparison with estimates of nutrient intake derived from liveweight gains of sheep. The dominant pasture species, Cortaderia pilosa, was the predominant species consumed during the cooler periods of the year. In the summer, when the highest liveweight gains of sheep occur, the proportion of fine grass species, including Poa spp., Festuca magellanica and Agrostis capillaris, and herbs and sedges in the diet was highest. Herbage intake was the highest during the summer periods when digestibility was also at its peak. Estimated nutritional deficiencies of metabolizable energy, crude protein, phosphorus and vitamin D3 that limit the growth and development of weaner sheep were evident for up to 9 months of the year. Targeted supplementation regimes that counter specific nutrient deficiencies could be developed on the basis of these results to address critical periods in the growth of young sheep.

    Development of Natural Killer Cell Activity and Genetic Resistance to Bone Marrow Transplantation with Age: Effect of Neonatal Thymectomy (1981)

    Notes: The effect of neonatal thymectomy on the development of splenic and bone marrow natural cell-mediated cytotoxicity and on genetic resistance to bone marrow transplantation was examined in mice. Natural cytotoxicity was measured by a 51Cr release assay; the ability to engraft foreign bone marrow was assayed by the spleen colony method. The natural cytolytic response of spleen cells increased progressively from youth to early adulthood, whereas that of the bone marrow declined during the same age period. Neonatal thymectomy significantly elevated the natural killer cell response of young mice only (4 weeks, spleen; 6 weeks, bone marrow). In other experiments, neonatally thymectomized and sham-operated mice were lethally irradiated at 4 or 6 weeks of age and injected with 2.5, 5.0 or 10 million rat marrow cells. Six days later spleen colonies were markedly reduced in both 4- and 6-week-old neonatally thymectomized mice with all rat marrow cell doses tested. Neonatal thymectomy did not alter the percentage of erythroid versus other colonies at either 4 or 6 weeks. In both thymectomized and sham-operated mice the number of colonies increased with increases in marrow cell dose. The data are suggestive of a production and dissemination to the spleen of cells involved in the natural cytotoxic response from the bone marrow.

    Reliability of progressive and additive MRI scoring systems for evaluation of haemophilic arthropathy in children: Expert MRI Working Group of the International Prophylaxis Study Group (2005)

    Notes: Summary.  Effective treatment of haemophilic arthropathy requires a detailed evaluation of joint integrity. Methodological assessment of magnetic resonance imaging (MRI) scores are needed to assure reproducibility of measurements when comparing results of clinical trials conducted in different centres. We compared the reliability of two MRI scoring systems for assessment of haemophilic arthropathy: one progressive system that displays the most severe change and one additive system that depicts osteochondral and soft tissue-related changes. A total of 47 1.5 T MRI examinations of knees (n = 21) and ankles (n = 26) of 42 haemophilic boys, age range, 22 months to 18 years, performed at different centres (Toronto, n = 20, Europe, n = 12 and Denver, n = 15) were independently reviewed by four radiologists at two occasions. Twenty-two examinations were from children 〈9 years and 25 from children ≥9. Sagittal and coronal gradient-echo (MPGR, 3D FLASH with fat saturation, GRASS) images were obtained. The MRI examinations of the ankle and knee studies presented with osteochondral abnormalities in 38.5% and 23.8% of the cases respectively. The two scoring systems demonstrated an excellent inter-reader [progressive, 0.88; additive (A, e, s and h components), 0.86] and intra-reader [progressive, 0.92; additive (A, e, s and h components), 0.93] reliability using intraclass correlation coefficients (ICCs). Although ICCs were slightly higher for knees when compared with ankles, and for older children when compared with younger children, all values fell within excellent inter- and intra-reader reliability categories. The two MRI scoring systems demonstrated a comparable reliability. This result constitutes the basis for further development of a combined MRI scoring system for assessment of haemophilic arthropathy, which incorporates progressive and additive components.

    Compatible scales for progressive and additive MRI assessments of haemophilic arthropathy (2005)

    Notes: Summary.  The international MRI expert subgroup of the International Prophylaxis Study Group (IPSG) has developed a consensus for magnetic resonance imaging (MRI) scales for assessment of haemophilic arthropathy. A MRI scoring scheme including a 10 step progressive scale and a 20 step additive scale with identical definitions of mutual steps is presented. Using the progressive scale, effusion/haemarthrosis can correspond to progressive scores of 1, 2, or 3, and synovial hypertrophy and/or haemosiderin deposition to 4, 5, or 6. The progressive score can be 7 or 8 if there are subchondral cysts and/or surface erosions, and it is 9 or 10 if there is loss of cartilage. Using the additive scale, synovial hypertrophy contributes 1–3 points to the additive score and haemosiderin deposition contributes 1 point. For osteochondral changes, 16 statements are evaluated as to whether they are true or false, and each true statement contributes 1 point to the additive score. The use of these two compatible scales for progressive and additive MRI assessments can facilitate international comparison of data and enhance the accumulation of experience on MRI scoring of haemophilic arthropathy.

    Immunoregulatory Pathways in Adult Responder Mice (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Scandinavian journal of immunology 19 (1984), S. 0 
    Details
    ISSN: 1365-3083
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: This report describes the alteration of helper-suppressor balances in an immune response (Ir) gene-controlled system by varying the route and form of antigen injection. Adult responder BALB/c mice develop Lyt 1+2-, T cells for delayed-type hypersensitivity (DTH), and T-cell proliferative (Tprlf) responses to subcutaneous injection of either poly(Glu60Ala30Tyr10) (GAT)-coupled syngeneic spleen cells (GAT-SP) or GAT emulsified in complete Freund's adjuvant. In contrast, intravenous injection of adult responders with GAT-SP results in specific unresponsiveness for DTH, Tprlf, interleukin-2, and plaque-forming cell (PFC) responses. This tolerance is mediated by both suppressor T cells (Ts) and a functional clonal inhibition. Lyt 1-2+ Ts suppress the induction (afferent limb) of GAT-specific DTH and PFC but not Tprlf responses. The reduced T-cell proliferation observed in GAT-tolerant mice is due to a non-transferable mechanism(s), possibly functional clonal inhibition. Our data are compatible with a multi-step pathway involving both proliferating and non-proliferating helper T (Th) cells. In addition, the fine specificity of tolerance induction for DTH and Tprlf responses was examined by using the related antigens poly(Glu60Ala40) (GA) and poly(Glu50Tyr50) (GT). Tolerance is exquisitely specific, as GA tolerizes responses to GA and GAT, whereas GT tolerizes GAT but not GA responses. Thus, both the route and form of antigen administration are important to the induction and regulation of immune response in Ir gene-controlled systems. Possible mechanisms governing the Th/Ts balance and the induction of GAT-specific tolerance and suppression for cellular and humoral responses in adult responders are discussed.

    Notes: Summary Daminozide [butanedioc acid mono-(2-2-dimethylhydrazide)] applied in the field reduced the electrical impedance of McIntosh apple fruit at harvest and after storage. Vacuum infiltration with calcium chloride (CaCl2) increased the impedance whether fruit were treated with daminozide or not.
