    CONTACT CHEMORECEPTION IN FEEDING BY PHYTOPHAGOUS INSECTS (2003)

    Notes: Abstract Gustatory receptors associated with feeding in phytophagous insects are broadly categorized as phagostimulatory or deterrent. No phytophagous insect is known that tastes all its essential nutrients, and the ability to discriminate between nutrients is limited. The insects acquire a nutritional balance largely "adventitiously" because leaves have an appropriate chemical composition. Sugars are the most important phagostimulants. Plant secondary compounds are most often deterrent but stimulate phagostimulatory cells if they serve as host-indicating sign stimuli, or if they are sequestered for defense or used as pheromone precursors. The stimulating effects of chemicals are greatly affected by other chemicals in mixtures like those to which the sensilla are normally exposed. Host plant selection depends on the balance of phagostimulatory and deterrent inputs with, in some oligophagous and monophagous species, a dominating role of a host-related chemical. Evolution of phytophagy has probably involved a change in emphasis in the gustatory system, not fundamentally new developments. The precise role of the gustatory systems remains unclear. In grasshoppers, it probably governs food selection and the amounts eaten, but in caterpillars there is some evidence that central feedbacks are also involved in regulating the amount eaten.

    Notes: Red porgy Pagrus pagrus from the north-eastern, north-western and south-western Atlantic were found to be genetically distinct as determined by mitochondrial DNA analysis. There were no shared composite restriction fragment haplotypes, and nucleotide sequence differences averaged 2% among these locations.

    The incidence of Fusarium moniliforme on maize from Central America, Africa and Asia during 1992–1995 (1997)

    Notes: Samples of maize seed were obtained from countries in Central America, Africa and Asia and assessed for fungal infection. Fusarium spp. were the largest single group of fungi present, and from these Fusarium moniliforme was the species most frequently isolated. Other fungi, including Stenocarpella (Diplodia) maydis, S. macrospora and Acremonium strictum, were also present in significant numbers. Isolates of F. moniliforme were characterized for mating populations, using RAPDs, and a number of isolates, taken at random from those assigned to specific mating groups, were also confirmed by crossing. Isolates were also characterized for fusaric acid production and significant differences in fusaric acid production were detected between isolates from different countries and regions within countries. A detailed analysis of isolates from one country, Kenya, was undertaken. The importance of the pathogens is discussed in relation to human, animal and seed health and quarantine regulations, and plant breeding objectives.

    Review article: the management of primary sclerosing cholangitis (1997)

    Notes: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by a progressive obliterating fibrosis of the intrahepatic and extrahepatic bile ducts. The pathogenesis of PSC is poorly understood but it is thought to be an immune-mediated disease. The optimal therapy which successfully improves symptoms, delays progression towards liver failure and transplantation and prevents the onset of cholangiocarcinoma remains elusive. Although current treatments are used to manage cholestasis and its consequences and some of the more general complications of the disease, none of the current therapeutic agents have been shown to retard and reverse the rate of disease progression. The role of cupruretics, corticosteroids, methotrexate, anti-fibrogenic agents and ursodeoxycholic acid in the treatment of PSC is reviewed. Orthotopic liver transplantation remains the only therapeutic option for advanced PSC but the timing of transplantation remains controversial and the possibility of recurrence of the disease in the graft is increasingly recognised. It is likely that greater insight into the pathogenetic mechanisms involved in PSC will allow therapy to be targetted more specifically at the biliary epithelium.

    Randomized comparison of photodynamic therapy with topical 5-fluorouracil in Bowen's disease (2003)
    Oxford, UK : Blackwell Science Ltd

    Notes: Summary Background Bowen's disease (BD; intraepithelial squamous cell carcinoma) is therapeutically challenging because lesions, which may be multiple, are frequently located at sites that heal poorly. There is a small risk of progression to invasive carcinoma. Photodynamic therapy (PDT) is an effective treatment for certain non melanoma skin cancers, but comparison studies with other, better-established therapies are limited. Objectives To compare the efficacy and tolerability of PDT and topical 5-fluorouracil (5-FU) in BD. Methods Forty patients from two centres were randomized to either topical PDT or 5-FU. The PDT group was treated with 20% 5-aminolaevulinic acid (ALA) applied 4 h before illumination with 100 J cm−2 narrowband red light (630 ± 15 nm). 5-FU was applied to lesions for 4 weeks. A repeat treatment cycle was performed after 6 weeks if required. Results Twenty-nine of 33 (88%) lesions treated with PDT initially responded completely, compared with 22 of 33 (67%) after 5-FU. After 12 months, two recurrences in the PDT group and six in the 5-FU group reduced complete clinical clearance rates to 82% and 48%, respectively. PDT was significantly more effective (P = 0·006, odds ratio 4·78, 95% confidence interval 1·56–14·62). In the 5-FU group, severe eczematous reactions developed around seven lesions, ulceration in three and erosions in two. No such reactions occurred following PDT. There was no difference in overall pain experienced during each therapy. Conclusions Topical ALA-PDT is more effective than topical 5-FU in the treatment of BD, with fewer adverse events. ALA-PDT should be considered one of the first-line therapeutic options for BD.

    The yrast spectroscopy of neutron-rich nuclei produced in deep-inelastic processes (2003)

    Notes: Abstract. The highly sensitive GASP array at the INFN Legnaro Laboratory was used to study the $\gamma$ -ray de-excitation of neutron-rich nuclei produced in the deep-inelastic processes which occur when 230 MeV 36S ions interact with a target of 176Yb. Yrast decay schemes were identified in over forty target-like fragments and in over twenty projectile-like fragments. Analysis of the data has resulted in extensions to the yrast decay sequences of the target-like species, 176Hf, 166Er, 172Yb, and 152Sm. New transitions have also been observed in a number of projectile-like species including 34P and 41Cl. Experimental results are compared with the results of shell model calculations.
