    LEKTI demonstrable by immunohistochemistry of the skin: a potential diagnostic skin test for Netherton syndrome (2004)

    Notes: Background   Netherton syndrome (NS) is a rare autosomal recessive condition characterized by ichthyosiform erythroderma, trichorrhexis invaginata and atopic manifestations. Confirming the diagnosis may be difficult in the early stages. Mutations in the SPINK5 gene which encodes for the serine protease inhibitor LEKTI are associated with NS. These mutations create premature termination codons which result in absent or abnormal expression of LEKTI in patients with NS.Objectives   To investigate the expression of LEKTI in the skin of patients with NS in comparison with normal controls and patients with other skin conditions, namely atopic dermatitis, psoriasis and nonbullous ichthyosiform erythroderma.Methods   Immunohistochemistry was performed on skin sections from four patients with NS, four normal controls, four with atopic dermatitis, two with psoriasis and two with nonbullous ichthyosiform erythroderma, using a primary rabbit polyclonal antibody against LEKTI.Results   LEKTI was localized to the stratum granulosum in normal skin. All four skin sections from patients with NS showed absent or very reduced staining for LEKTI. Staining in the other disorders showed positive LEKTI expression in varying patterns.Conclusions   NS can be difficult to diagnose especially in the early stage, which can lead to inappropriate treatments particularly if it is misdiagnosed as atopic dermatitis. Immunohistochemistry of skin with an antibody against LEKTI is a potentially useful diagnostic test for NS.

    Soft tissue tumours in childhood (1993)

    Notes: The spectrum of soft tissue tumours in youg adults is very similar to that in more mature individuals, while those in childhood form a distinct group rarely seen outside the first decade. The majority of these are benign vascular or fibroblastic proliferations; in young children they may be highly cellular and mitotically active, but malignancy should be diagnosed with caution. Congenital soft tissue tumours constitute a special group in which the clinical outcome may be particularly difficult to predict from the histological appearances. This review focuses on those malignant soft tumours which are either peculiar to childhood or which manifest special features in childhood. Some recently recognized benign soft tissue tumours which occur mainly in childhood are also described. The fibromatoses are not discussed. As a guide to the appropriate treatment regime, the main histological distinctions to be drawn are between: 1 tumours of neuroectodermal origin (Ewing's sarcoma and primitive neuroectodermal tumour); 2 other sarcomas; and 3 the fibromatoses and other benign and potentially locally aggressive lesions requiring local excision. Immunohistochemical staining may be of considerable help in achieving the correct diagnosis, but it is vital that a panel of antibodies be applied and the results critically assessed. Cytogenetic analysis is also of growing importance, characteristic karyotypic abnormalities having been demonstrated in Ewing's sarcoma/primitive neuroectodermal tumour, alveolar rhabdomyosarcoma and synovial sarcoma.

    The distribution of xylem hydraulic resistance in the fruiting truss of tomato (2001)

    Notes: The distribution of hydraulic resistances in xylem throughout the pathway leading to the tomato fruit was investigated. Previous work had indicated that there were large resistances within the supporting sections of this pathway (the peduncle and pedicel), perhaps associated with interruptions in the xylem. These high resistances are believed to impede calcium flux into the fruit and thus impair fruit development. It is shown here that fruit on intact plants do not shrink detectably during drought, even when the drought is sufficient to cause marked shrinkage of leaves and visible wilting of the shoot. In explants, it is possible to induce back-flow from the fruit into the stem (probably via the xylem) but this flow is small and very slow. These observations support the view that there is a large hydraulic resistance in the pathway between fruit and stem. When pulses of water were made available within explants, by scorching of one leaflet, there was a rapid swelling of leaves and sepals. Such rapid fluxes indicate the presence of strong hydraulic (xylem) connections throughout the pathway between leaf and calyx. This shows that there are no significant hydraulic constrictions in the xylem proximal to the calyx. This finding is contrary to some previous conclusions but it is supported by experiments with dyes which showed continuous, functional xylem throughout the peduncle and pedicel. Calculations show that over 90% of the hydraulic resistance between stem and fruit must reside within the fruit pericarp. Implications for calcium nutrition are discussed.

    Peroxidase isozyme patterns in the skin of maturing tomato fruit (2000)
    Oxford, UK : Blackwell Science Ltd

    Notes: The cessation of tomato fruit growth is thought to be induced by an increase in the activity of enzymes which rigidify cell walls in the fruit skin. Peroxidase could catalyse such wall-stiffening reactions, and marked rises in peroxidase activity were recently reported in skin cell walls towards fruit maturity. Peroxidase isoforms in the fruit are here analysed using native gel electrophoresis. New isoforms of apparent Mr 44, 48 and 53 kDa are shown to appear in cell walls of the fruit skin at around the time of cessation of growth. It is inferred that these isozymes are present in the cell wall in vivo. Fruit from a range of non-ripening mutants were also examined. Some of these do not soften or ripen for many weeks after achieving their final size. The new isozymes were found in skin cell walls of mature fruit in each of these mutants, as in the wild-type and commercial varieties. It is concluded that the late-appearing isozymes are not associated with fruit ripening or softening, and are probably not ethylene-induced. They may act to control fruit growth by cross-linking wall polymers within the fruit skin, thus mechanically stiffening the walls and terminating growth.

    Surface potentials and hydraulic signals in wheat leaves following localized wounding by heat (1991)

    Notes: Abstract. Localized burning of a leaf causes a rapid change in apoplastic electrical potential throughout the shoot of wheat seedlings (‘variation potential’). It also causes marked increases in turgor pressure in epidermal cells of adjoining leaves. These turgor increases indicate rapid propagation throughout the seedling, of a hydraulic pressure wave from the site of wounding. Evidence is presented that this pressure wave is caused by relief of xylem tension, by water released from damaged cells in the wounded region. It is demonstrated that, in the absence of wounding, pressure waves imposed at the tip of one leaf can travel to neighbouring leaves, and can there induce change in apoplastic electrical potential similar to a ‘variation potential’. This indicates that the hydraulic event produced by wounding is the signal responsible for systemic induction of the ‘variation potential’. This signal has been termed ‘Ricca's factor’. It is suggested that arrival of the hydraulic wave alters leaf water potential and thereby induces stomatal activity. Leaf surface potential may be dominated by electrogenic ion pumping or flux at stomatal cells, and the ‘variation potential’ may therefore be a reflection of stomatal activity induced by the hydraulic signal.
