The results show no significant correlation between in vivo resistance and in vitro tolerance to culture filtrate of the fungus, while there was a good correlation in die case of phytoalexin production. Moreover, the character phytoalexin production behaved as a dominant in the crosses between a resistant and a susceptible cultivar.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1460-9568Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The goal of this study was to characterize the stretch-activated ion channels (SACs) of adult identified neurons of the leech Hirudo medicinalis and to test the role of SACs in neurite outgrowth of isolated cells. Using cell-attached patch recording, we established that SACs are densely distributed in the growth cone membrane of cultured neurons. In excised patches, we found that these channels are permeable to Ca2+, as well as to monovalent cations. The channels are blocked by the extracellular application of gadolinium (Gd3+), amiloride and gentamicin. Amiloride and gentamicin, respectively, induce a partial and complete voltage-dependent block. Time-lapse video recordings of neurite outgrowth from single cultured neurons were used to study the effects of blocking SACs with gentamicin. Within 20 h of plating in the presence of the aminoglycoside, the total length of neuronal arborization was significantly greater than that measured in its absence. The amount of assembled axon per unitary surface area remained constant over 40 h and did not differ significantly with or without gentamicin. Our findings show that SACs of leech neurons admit Ca2+, are densely distributed in the growth cone membrane and exhibit typical pharmacological features of mechanotransducer ion channels. In addition, our data suggest that these cation channels participate in the early interaction between growing neurites and culture substrate.Type of Medium: Electronic ResourceURL: -

Published 2005Staff ViewISSN: 1365-2036Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background: Acid suppression plus two antibiotics is currently considered the gold standard anti-Helicobacter pylori treatment, but the effective role of gastric antisecretory drugs is still poorly understood.Aims: To compare a 14-day ranitidine-based triple regimen against Helicobacter pylori with one based on omeprazole, and to study the influence of antisecretory drugs on metronidazole pharmacokinetics in human plasma.Methods: A total of 150 dyspeptic H. pylori-infected patients were randomized for ranitidine 300 mg b.d. (RCM group) or omeprazole 20 mg b.d. (OCM group) 14-day triple therapy, with clarithromycin 500 mg b.d. and metronidazole 500 mg b.d. On the eighth day of therapy, metronidazole pharmacokinetics was studied in plasma by high-performance liquid chromatography. The pharmacokinetic parameters (terminal half-life, area under the curve, peak-plasma level, peak time) of metronidazole were computed using standard non-compartmental methods. H. pylori status was monitored before and 4 weeks after the end of therapy by histology, serology and rapid urease test.Results: On an intention-to-treat basis, eradication rates were 91 and 76% for the RCM and OCM groups respectively (P 〈 0.02). Significantly different pharmacokinetic parameters of metronidazole were found between the groups: peak-plasma level (P 〈 0.01) and area under the curve (P 〈 0.02).Conclusion: Our results show that the RCM regimen was more effective than that based on OCM and that the antisecretory drugs affected metronidazole availability, increasing the efficacy of ranitidine-based regimens.Type of Medium: Electronic ResourceURL: -

In the lesioned aging rats, the number of choline acetyltransferase-immunoreactive neurons of the nucleus basalis magnocellularis was markedly reduced in the ipsilateral side and to a lesser extent in the contralateral side. Twenty-one days after the lesion, the activity of choline acetyltransferase in the ipsilateral cortex was reduced by 40% in both groups of rats and by 24% in the contralateral frontal cortex of the aging rats. Intracerebroventricular administration of nerve growth factor (10 μg, twice a week) to aging lesioned rats for 3 weeks after surgery resulted in a complete recovery in the number of choline acetyltransferase-immunoreactive neurons in the nucleus basalis of both sides, and choline acetyltransferase activity in the contralateral cortex, with little effect on the ipsilateral cortex. No potentiation was seen after the concurrent administration of GM1 ganglioside and nerve growth factor. Complete recovery in cortical choline acetyltransferase activity was only observed in the lesioned rats treated with nerve growth factor for 1 week before and 3 weeks after lesioning. Nerve growth factor treatment, both after the lesion, and before and after the lesion, improved the passive avoidance performance disrupted by the lesion. In young lesioned rats daily intraperitoneal administration of GM1 (30 mg/kg) for 21 days after surgery promoted both the recovery of choline acetyltransferase activity and passive avoidance performance. In aging rats GM1, even at a dose twice as large, failed to reverse the biochemical and morphological deficits and behavioral impairment induced by the lesion. Only when GM1 administration was started 3 days before the lesion, were a complete recovery in choline acetyltransferase activity in the contralateral cortex and a partial recovery in the ipsilateral cortex obtained. Our results indicate that nerve growth factor and, to some extent, GM1 facilitate the recovery of the cholinergic neurons after a lesion of the nucleus basalis in aging rats, but their efficacy is reduced. The lower efficacy of GM1 as compared to NGF might be due to the different routes of administration used.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1432-0568Keywords: Key words Urogenital system ; Gene expression ; Homeobox ; Kidney ; Gonads ; DevelopmentSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract The development of the urogenital system has always attracted many investigators owing to the peculiar aspects of the embryology of the reproductive and excretory organs and to the high number of congenital anomalies related to these structures. It is remarkable because of the common origin of the kidneys, gonads, and genital tracts from the intermediate mesoderm and because differentiation of these organs involves extensive mesenchyme to epithelium transition. Our knowledge about the molecular mechanisms controlling the differentiation of these diverse structures from the same precursor has taken advantage of gene expression data and gene-targeting experiments using genes with a specific expression pattern in the urogenital system. A more detailed function in kidney development has been postulated for transcription factors such as WT-1, Pax-2 or other molecules such as glial cell line-derived neurotrophic factor (GDNF), Wnt-4, c-ret. In the present work we have described the expression pattern of the homeobox-containing gene Emx2 during the development of the urogenital system in mouse embryos. We have found that Emx2 is expressed in the early primordia of the organs that will form the excretory and reproductive systems. In particular we have found that Emx2 is expressed in the epithelial components of pronephros and mesonephros, in Wolffian and Müllerian ducts, in the ureteric buds with their branches and in the early epithelial structures derived from metanephrogenic mesenchyme. Emx2 is also intensely expressed in the ”bipotential” or ”indifferent” gonads and ovaries. These data and the recent finding that Emx2 homozygous mutant mice die soon after birth because of the absence of kidneys indicate an essential role of Emx2 in the morphogenesis of the urogenital system.Type of Medium: Electronic ResourceURL: -

This approach is based on mapping lines inR 3 into points and hyperplanes in five-dimensional projective space (Plücker space). We obtain new results on the following problems: 1. Preprocessn triangles so as to answer efficiently the query: “Given a ray, which is the first triangle hit?” (Ray- shooting problem). We discuss the ray-shooting problem for both disjoint and nondisjoint triangles. 2. Construct the intersection of two nonconvex polyhedra in an output sensitive way with asubquadratic overhead term. 3. Construct the arrangement ofn intersecting triangles in 3-space in an output-sensitive way, with asubquadratic overhead term. 4. Efficiently detect the first face hit by any ray in a set of axis-oriented polyhedra. 5. Preprocessn lines (segments) so as to answer efficiently the query “Given two lines, is it possible to move one into the other without crossing any of the initial lines (segments)?” (Isotopy problem). If the movement is possible produce an explicit representation of it.Type of Medium: Electronic ResourceURL:
