Paleomagnetism of basalts from ODP Hole 109-648A

Paleomagnetic parameters of 55 basalt samples from Hole 648B on the Mid-Atlantic Ridge were studied. Negative NRM inclinations were found for 10 samples between 10 and 25 m sub-bottom depth. Several hypotheses related to this phenomenon are discussed. NRM intensities, susceptibilities, median destructive fields, and Koenigsberger ratios are slightly different for pillow and massive basalts. One can suggest from measured parameters that magnetic carriers for massive and pillow basalts are PSD titanomagnetite grains more or less close to PSD-MD threshold size with a low degree of alteration.

Geochemistry of basalts from Serocki Volcano

Basalts collected during drilling and diving programs on Serocki Volcano mostly fall within a limited compositional range, and are moderately evolved, normal MORBs with distinctive high MgO contents (averaging 7.60 wt%) and high A1203 concentrations (averaging 16.14 wt% in whole rock samples). However, samples recovered from within the central crater have lower Ti02 and FeO*/MgO, and higher MgO and Al2O3 concentrations, and are most similar to glasses recovered at Site 649 about 45 km to the north. Comparison of the observed geochemical variations with low-pressure experimental work and other samples from the region suggests that the Serocki Volcano and Site 649 data are compatible with crystal-liquid fractionation involving both olivine and early-stage clinopyroxene, as well as plagioclase, and that the sources may be similar even though Sites 648 and 649 are located in different, but adjacent, spreading cells. Consideration of the stratigraphy and morphology of Serocki Volcano suggests that this feature is more properly described as a megatumulus or lava delta, associated with a steeper, conical peak to the southwest. The evolution of Serocki Volcano involved early construction of a marginal rampart of pillows, followed by doming of this feature and the formation of a perched lava pond. Draining of this pond resulted in collapse and the formation of the central crater.

The mitochondrial genome of the phytopathogenic basidiomycete Moniliophthora perniciosa is 109 kb in size and contains a stable integrated plasmid

We present here the sequence of the mitochondrial genome of the basidiomycete phytopathogenic hemibiotrophic fungus Moniliophthora perniciosa, causal agent of the Witches` Broom Disease in Theobroma cacao. The DNA is a circular molecule of 109103 base pairs, with 31.9 % GC, and is the largest sequenced so far. This size is due essentially to the presence of numerous non-conserved hypothetical ORFs. It contains the 14 genes coding for proteins involved in the oxidative phosphorylation, the two rRNA genes, one ORF coding for a ribosomal protein (rps3), and a set of 26 tRNA genes that recognize codons for all amino acids. Seven homing endonucleases are located inside introns. Except atp8, all conserved known genes are in the same orientation. Phylogenetic analysis based on the cox genes agrees with the commonly accepted fungal taxonomy. An uncommon feature of this mitochondrial genome is the presence of a region that contains a set of four, relatively small, nested, inverted repeats enclosing two genes coding for polymerases with an invertron-type structure and three conserved hypothetical genes interpreted as the stable integration of a mitochondrial linear plasmid. The integration of this plasmid seems to be a recent evolutionary event that could have implications in fungal biology. This sequence is available under GenBank accession number AY376688.

Recurrent gains and losses of large (84-109 bp) repeats in the rDNA internal transcribed spacer 2 (ITS2) of rhipicephaline ticks

We studied the internal transcribed spacer 2 (ITS2) in twenty-two spp. of ticks from the subfamily Rhipicephalinae. A 104-109 base pair (bp) region was Imperfectly repeated In most ticks studied. Mapping the number of repeat copies on to a phylogeny from the ITS2 showed that there have been many Independent gains and losses of repeats. Comparison of the sequences of the repeat copies Indicated that in most taxa concerted evolution had played little if any role in the evolution of these regions, as the copies clustered by sequence position rather than species, In our putative secondary structure, each repeat copy can fold into a distinct and almost identical stem-loop complex; a gain or loss of a repeat copy apparently does not impair the function of the ITS2 in these ticks.

A Five Year Tobacco Action Plan (PDF 109 KB)

Summary of Responses to the Consultation ‘A Five Year Tobacco Action Plan’ document was issued for public consultation in August 2002. The Plan, which was developed by an inter-sectoral Working Group, provides a framework for collaborative working across Government departments, the statutory and voluntary sectors, as well as with business and in local communities. It seeks to combine an overview of the background, scale and nature of the problem with a comprehensive programme of action to reduce the harm caused by tobacco use. åÊ

Post-partum persistence of abnormal circadian pattern of blood pressure after preeclampsia [109-POS]

OBJECTIVES: Blunted nocturnal dip of blood pressure (BP) and reversed circadian rhythm have been described in preeclampsia (PE). Non-dipper status and preeclampsia are both associated with an increased risk of cardiovascular disease later in life. Complete recovery of BP in PE is reported to occur over a variable period of time. Twenty-four hours-ambulatory blood pressure measurement (ABPM) in the post-partum follow-up after a PE has not been described. The aim of this study was to assess 24h-ambulatory blood pressure pattern after a PE and to determine the prevalence of non-dipper status, nocturnal hypertension, white coat hypertension and masked hypertension. METHODS: This is an observational, prospective study on women who suffered from a preeclampsia. A 24h-ABPM was done 6 weeks post-partum at the Hypertension Unit of the University Hospitals of Geneva, concomitantly with a clinical and biological evaluation. RESULTS: Forty-five women were included in a preliminary analysis. Mean age was 33±6years, 57.3% were Caucasian, mean BMI before pregnancy was 24±5kg/m(2). Office and ambulatory BP are shown in Table 1. Prevalence of nocturnal hypertension was high and half of the women had no nocturnal dipping. The diagnosis of hypertension based on office BP was discordant with the diagnosis based on ABPM in 25% of women. CONCLUSIONS: The prevalence of increased nighttime BP and abnormal BP pattern is high at 6weeks post-partum in preeclamptic women. Early assessment of BP with ABPM after preeclampsia allows an early identification of women with persistent circadian abnormalities who might be at increased risk. It also provides a more accurate assessment than office BP. DISCLOSURES: A. Ditisheim: None. B. Ponte: None. G. Wuerzner: None. M. Burnier: None. M. Boulvain: None. A. Pechère-Bertschi: None.

Genetic and phenotypic characterization of isolates of Pyricularia grisea from the rice cultivars epagri 108 and 109 in the State of Tocantins

An epidemic of rice (Oryza sativa) blast occurred on cultivars Epagri 108 and 109 in the municipalities of Lagoa da Confusão and Duerê in the State of Tocantins, during the rice-growing season 1998-99. DNA fingerprinting and virulence phenotype analysis were utilized to determine the diversity of Pyricularia grisea isolates collected from these cultivars in one epidemic year. Rep-PCR analysis of isolates was done by using two primer sequences from Pot2. Two distinct fingerprint groups or lineages were identified among 53 isolates collected from nine different commercial fields. The virulence pattern of isolates retrieved from these two cultivars was analyzed in artificial inoculation tests utilizing 32 genotypes in the greenhouse. A dendrogram constructed from virulence phenotype data showed a single group considering 77% similarity level. The predominant pathotype IB-45 was represented by 47 of the 53 isolates corresponding to 83%. Four other pathotypes (IB-1, IB-9, IB-13 and IB-41) were identified at random among the isolates from these cultivars. There was no relation between rep-PCR grouping and pathotypes. The results showed that the isolates of P. grisea recovered from cultivars Epagri108 and 109 in farmers' fields had narrow phenotypic and genetic diversity. The blast outbreak on these two cultivars one year after their introduction could be attributed to the new pathotype IB-45 or its increase, which was hitherto existing in low frequency.
