    Notes: Abstract: Prosaposin, the precursor of saposins A, B, C, and D, was recently identified as a neurotrophic factor in vitro as well as in vivo. Its neurotrophic activity has been localized to a linear 12-amino acid sequence located in the NH2-terminal portion of the saposin C domain. In this study, we show the colocalization of prosaposin and ganglioside GM3 on NS20Y cell plasma membrane by scanning confocal microscopy. Also, TLC and western blot analyses showed that GM3 was specifically associated with prosaposin in immunoprecipitates; this binding was Ca2+-independent and not disassociated during sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The association of prosaposin-GM3 complexes on the cell surface appeared to be functionally important, as determined by differentiation assays. Neurite sprouting, induced by GM3, was inhibited by antibodies raised against a 22-mer peptide, prosaptide 769, containing the neurotrophic sequence of prosaposin. In addition, pertussis toxin inhibited prosaptide-induced neurite outgrowth, as well as prosaptide-enhanced ganglioside concentrations in NS20Y cells, suggesting that prosaposin acted via a G protein-mediated pathway, affecting both ganglioside content and neuronal differentiation. Our findings revealed a direct and right GM3-prosaposin association on NS20Y plasma membranes. We suggest that ganglioside-protein complexes are structural components of the prosaposin receptor involved in cell differentiation.

    Notes: The rate of nonenzymatic browning was compared in freeze-dried model systems containing lysine and glucose, sucrose or trehalose at pH 2.5 and a water activity of 0.33. Rate constants for brown color formation (A420) were from 200 to 2000-fold greater for the sucrose than for the trehalose system. Some rate constants for sucrose browning approached those for glucose, indicating that extensive hydrolysis had occurred. The results indicate that use of trehalose rather than sucrose may be of value in stabilizing some systems vulnerable to nonenzymatic browning.

    Description / Table of Contents: Summary Fucosidosis, a rare lysosomal storage disease due to nearly complete deficiency of α-L- fucosidase, was diagnosed in two unrelated male German patients who exhibited typical symptoms of this disorder including mental retardation, dysostosis multiplex, vacuolization of lymphocytes and progressive neurologic deterioration by the age of 3.2 and 4 years, respectively. In both cases, activity of α-L-fucosidase in leukocytes and cultivated fibroblasts was negligible. DNA analysis revealed a nonsense mutation (G401X) in exon 7 of the fucosidase gene; this leads to a premature stop codon and C-terminal deletion of 61 amino acids from the protein. Discussion: On account of the mutation a unique PFlMI restriction site is obliterated; this simplifies molecular diagnosis of the G401X mutation. So far, the mutation G401X has not been found in any other population.
    Notes: Zusammenfassung Die Fukosidose ist eine seltene lysosomale Speicherkrankheit, die durch eine starke Verminderung der Enzymaktivität der α-L-Fukosidase verursacht wird. Wir beschreiben 2 nicht verwandte, deutsche, männliche Patienten mit typischen Symptomen. Beide zeigten bis zum Alter von 3,2 bzw. 4 Jahren einen progredienten neurologischen Abbau, eine schwere mentale Retardierung, Zeichen einer Dysostosis multiplex und Speicherphänomene in Lymphozyten. Die α-L-Fukosi- dase-Aktivität in Leukozyten und Fibroblasten war stark vermindert (〈3% des Normalwertes). Die molekulargenetische Diagnostik deckte eine Nonsense-Mutation (G401X) in Exon 7 des α-L-Fukosidase-Gens auf, die zu einem vorzeitigen Stopkodon und so zum C-terminalen Verlust von 61 Aminosäuren des Enzymproteins führt. Diskussion: Durch die Mutation geht eine Spaltstelle des Restriktionsenzyms PflMI verloren, so daß ein rascher Nachweis mit Hilfe dieses Polymorphismus möglich ist. Bisher wurde die Mutation G401X in keiner anderen Population nachgewiesen.

    Notes: Abstract The radiographic fusion rates, graft behaviour and clinical outcome of 41 patient with simultaneous combined anterior lumbar interbody fusion and posterior arthrodesis with translaminar screws were reviewed independently. In all patients a femoral cortical allograft (FCA) ring filled with autologous iliac crest cancellous bone was used anteriorly to replace the disc and achieve interbody fusion. The follow-up averaged 30.6 months, with a minimum follow-up of 24 months. All patients had disabling low-back pain with different degrees of radiating leg pain and either discogenic pain (n = 24) or a postdiscectomy syndrome (n = 15) respectively post-fusion syndrome (n = 2). The overall fusion rate was 95.2% (59 of 62 segments). Time to radiographic fusion averaged 8.7 months (range 2–34 months), and in 66.1% radiographic fusion occurred without significant subsidence. In 18.6% fusion with subsidence resulted from resorption of the FCA and in 15.3% the FCA had protruded into the vertebral body. The posterior intervertebral disc height (PIVDH) increased postoperatively by 2 mm on average. However, loss of PIVDH was the rule, and occurred within the first 12 postoperative months, resulting in a negligible final gain in height of 0.3 mm on average. The segmental lordosis was increased by 3°; however, loss of lordosis during the first 6 postoperative months led to a final gain in lordosis of 1.3° on average. Graft incorporation occurred in 16 of 62 segments (25.8%) and was observed at an average of 21.9 months postoperatively. Subjectively, 82.4% of the patients were satisfied or highly satisfied with the clinical result of the fusion operation. In conclusion, the described technique has proven to be highly effective in achieving a high fusion rate with a good patient outcome.
