    Notes: Abstract A 23-year-old man presented with a 2-week history of intracranial hypertension. CT showed a large, nonenhancing cerebellar mass with surrounding calcification and displacement of the fourth ventricle. MRI revealed a septate lesion, with low signal on T1-weighted and high signal on T2-weighted images. The cerebellar tonsils were displaced below the foramen magnum and there was associated syringomyelia. The MRI features were characteristic of Lhermitte-Duclos (LD) disease (dysplastic gangliocytoma) and the diagnosis was confirmed following surgery. In this case, we emphasise the usefulness of MRI in the diagnosis of LD disease and consider the possible pathogenesis of the associated syringomyelia.

    Pediatric renal transplantation into the abnormal urinary tract (1996)
    Springer
    Pediatric nephrology 10 (1996), S. 113-120 
    Details
    ISSN: 1432-198X
    Keywords: Key words: Renal transplantation ; Abnormal urinary tract
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract. Many children with end-stage renal disease have significant urinary tract problems other than irreversible loss of native kidney function. These significant other urinary tract problems, if not corrected prior to transplantation, may significantly increase recipient mortality, graft loss, and patient morbidity. These other urinary tract problems may cause hydroureteronephrosis in the transplanted kidney, lead to an increased incidence of graft rejection, be the source of sepsis after subsequent immunosuppression, and cause hypertension. In addition, pre-existing urinary diversion, large interabdominal masses, or previous cancer require specific pre-transplant management plans. Potential pediatric transplant recipients with other significant urinary tract problems can be classified according to three parameters: anatomical extent, pathology, and pathophysiology of the significant other problems. Particular attention must be paid to pre-existing lower tract problems. Strategy must be worked out pre transplant as to how the lower urinary tract is going to store, hold, and empty urine. The means for assessing the potential recipients and strategies and techniques for correcting pre-existing problems have been summarized in this article.

    Transient expression of a novel serine protease in the ectoderm of the ascidian Herdmania momus during development (1997)

    Development genes and evolution 206 (1997), S. 455-463

    Notes: Abstract  We have studied gene expression during ascidian embryonic development using the technique of differential display and isolated partial cDNA sequences of 12 genes. Developmental regulation of these genes has been confirmed by northern hybridization analysis. Further cDNA cloning and sequence analysis of an mRNA that is present during gastrulation, neurulation and tailbud formation reveals that it encodes a novel serine protease containing a single kringle motif and catalytic domain. The spatial expression of this gene, designated Hmserp1, is restricted to precursor cells of the epidermis. The structure and expression of Hmserp1 is discussed in relation to possible functions during development.

    Chymotrypsin mRNA expression in digestive gland amoebocytes: cell specification occurs prior to metamorphosis and gut morphogenesis in the gastropod, Haliotis rufescens (1995)
    Springer
    Development genes and evolution 205 (1995), S. 97-101

    ISSN: 1432-041X
    Keywords: Chymotrypsin ; Larva ; Metamorphosis Mollusc ; In situ hybridization

    Notes: Abstract In the non-feeding larva of the marine gastropod, Haliotis rufescens, gut morphogenesis is initiated at metamorphosis. Intestine-specific chymotrypsin gene expression begins in amoebocytes located in the dorsoposterior region of the undifferentiated digestive gland prior to metamorphosis, 5 d post-fertilization. Transcript accumulates steadily in these cells over the next 6 d while the amoebocytes migrate slowly dorsally. Induction of metamorphosis dramatically accelerates the rates of chymotrypsin mRNA accumulation and amoebocyte migration, and is required for homing of the amoebocytes to the hindgut region. Induction of chymotrypsin gene expression occurs only in larvae that had developed competence to recognize an exogenous morphogenetic cue and initiate metamorphosis, with a more pronounced increase in chymotrypsin mRNA accumulation in occurring older larvae. Chymotrypsin mRNA accumulation patterns suggest that hindgut cell specification occurs prior to metamorphosis, but that completion of the morphogenetic program requires signaling events associated with metamorphosis.

    Biochemical characterization of lines descended from 8x triticale x 4x triticale cross (1990)
    Springer
    Theoretical and applied genetics 79 (1990), S. 646-653 
    Details
    ISSN: 1432-2242
    Keywords: Triticale ; Interspecific hybridization ; Genome rearrangement ; Biochemical markers ; Electrophoresis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Fifty-two progenies originating from a cross between 8x and 4x triticale were submitted to cytogenetic analyses and to various electrophoretic studies [high-molecular-weight (HMW) glutelins, HMW secalins, γ-secalins, α and ω-gliadins, β-amylases] to identify new genetic structures, more specifically the input of the D genome in a genetic context other than the wheat one. Markers of the rye genome (HMW and ω-secalins) were identified in all of the triticale lines, but they originated either from the 4x or from the 8x parent, or from both. Chromosomes 4A, 1B, and 2R, present in both parents, showed the same banding patterns in all progenies. Chromosomes 1R and 5R, present in both parents, showed heterogeneous labelling. The expression of chromosomes 6A, 1D, and 4D, present in the 8x parent only, was more complex with a possible involvement of a regulatory system. Several hexaploid progenies had introgressed part of the D genome, suggesting that crossing 8x and 4x triticale was a practicable approach for transferring D chromosomes into hexaploid triticale.

    Meiotic pairing in hybrids between tetraploid Triticale and related species: new elements concerning the chromosome constitution of tetraploid Triticale (1985)
    Springer
    Theoretical and applied genetics 70 (1985), S. 390-399 
    Details
    ISSN: 1432-2242
    Keywords: Tetraploid triticale ; Chromosome pairing ; Interspecific hybridization ; Genome re-arrangement ; Genome affinity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Two F5 strains of tetraploid triticale (2n= 4x=28), obtained from 6x triticaleX2 rye progenies, were crossed with diploid and tetraploid rye, some durum and bread wheats, and various 8x and 6x triticale lines. Meiosis in the different hybrid combinations was studied. The results showed that the haploid complement of these triticales consists of seven chromosomes from rye and seven chromosomes from wheat. High frequencies of PMCs showing trivalents were observed in hybrids involving the reference genotypes of wheat and triticale. These findings proved that several chromosomes from the wheat component have chromosome segments coming from two parental wheat chromosomes. The origin of these heterogeneous chromosomes probably lies in homoeologous pairing occurring at meiosis in the 6x triticaleX2x rye hybrids from which 4x triticale lines were isolated. A comparison among different hybrids combinations indicated that the involvement of D-genome chromosomes in homoeologous pairing is quite limited. In contrast, meiotic patterns in 4x triticale X 2x rye hybrids showed a quite high pairing frequency between some R chromosomes and their A and B homoeologues.
