RASA1-related disease is a rare autosomal dominant disease characterized by capillary malformations, arteriovenous malformations (AVMs), and/or arteriovenous fistulas (AFVs). Penetrance is nearly complete and vascular malformations may cause serious complications such as organ injury due to oxygenation disorder, brain abscess, hemorrhage, and stroke. Early diagnosis is useful in order to discuss optimal management, including AVMs/AVFs embolization or surgical procedures, and try to prevent some of the complications. In this context, molecular testing of RASA1 gene mutation in relatives may help to better manage the family. All arteriovenous malformations are however not accessible to such procedures. In addition, these therapeutic procedures may result in potential side effects and complications. A couple was referred to our genetics unit and asked us for prenatal genetic testing about a RASA1 mutation. Here, we discuss about arguments that led our team to accept prenatal testing. To the best of our knowledge, no molecular prenatal diagnosis was reported until now in RASA1-related diseases. This first report of prenatal diagnosis in RASA1-related diseases may also offer perspectives for a more general discussion in the field of inherited arteriovenous malformations. 相似文献

The cicada species Tibicina haematodes and Cicada orni are two sympatric species often inhabiting vineyards. We show that they occupy two distinct levels: males of T. haematodes produce their calling songs from a high position in vine foliage while males of C. orni call from a low position near the ground on vine trunks. Experiments consisting of broadcasting and re-recording experimental signals in natural habitats from low and high positions show that signals are more and more modified as sender–receiver distance increases. T. haematodes would have an advantage when calling on trunks rather than on branches whereas C. orni would be able to call indiscriminately from both low and high positions. Thus, the microhabitat segregation observed between T. haematodes and C orni in vineyards does not seem to be related to calling song propagation constraints, but may be due to other ethological or ecological factors. 相似文献

On-site continuous measurement of nitrate in the River Taw situated in Devon (UK) was performed automatically for two months using a recently developed ion-selective electrode (ISE). A non-submersible electrode support system was developed and a field instrument was constructed comprising the nitrate-ISEs, a reference electrode and a temperature probe connected through a pre-amplifier to a data-logger and battery supply. The nitrate-ISE was constructed using a commercially available electrode body with a membrane incorporated into the tip. This rubbery membrane contained the sensor molecule (N,N,N-triallylleucine betaine chloride, 6.5% m/m) covalently bound to polystyrene-block-polybutadiene-block-polystyrene, SBS, (43.5% m/m), with 2-nitrophenyloctyl ether (2-NPOE) as mediator (40% m/m). The Nernstian slope was -59.1 mV per decade over a linear range of 1400-0.07 mg L(-1) nitrate-N. The limit of detection was 0.007 mg L(-1) nitrate-N with a selectivity coefficient for nitrate against chloride (k(pot)NO3-, Cl-) of 3.4 x 10(-3). The speed of response was less than a minute over the linear Nernstian range. The lifetime in the laboratory exceeded 5 months with no potentiometric drift over the linear Nernstian range. A temperature correction algorithm was also used to accomodate the temperature changes encountered in the river. The river nitrate results obtained with the ISEs at hourly intervals compared very favourably (R2 = 0.9) with those obtained with laboratory automated chemical determinations made on contemporaneous river samples over a concentration range 0.55-2.00 mg L(-1) nitrate-N. The ISEs did not require re-calibration and no deterioration in performance or fouling of the membrane surface was observed during 40 days. 相似文献

The purpose of the present research was to demonstrate that the perceived importance of wages is a function of thermal climate and national wealth. As hypothesized, analyses of 37 nationally representative samples of 22 483 blue‐ and white‐collar workers and 5544 managers show that wages are perceived as more important in poorer countries with colder climates (e.g., Azerbaijan) than in richer countries with colder climates (e.g., Canada) and in poorer and richer countries with temperate climates (e.g., Uganda, Singapore). The results suggest that performance‐related pay may be most effective in poorer countries with colder climates. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Partly because of the low bioavailability of metals, the soil cleaning-up using phytoremediation is usually time-consuming.
In order to enhance the amount of metals at the plant's disposal, the soil bioaugmentation coupled together with phytoextraction
is an emerging technology. In this preliminary work, two agricultural soils which mainly differed in their Cr, Hg and Pb contents
(LC, low-contaminated soil; HC, high-contaminated soil) were bioaugmented in laboratory conditions by either bacterial (Bacillus subtilis, Pseudomonas aeruginosa, Pseudomonas fluorescens or Ralstonia metallidurans) or fungal inocula (Aspergillus niger or Penicillium simplicissimum) and incubated during three weeks. The LC soil pots bioaugmented with A. niger and P. aeruginosa contained higher concentrations of Cr (0.08 and 0.25 mg.kg−1 dw soil) and Pb (0.25 and 0.3 mg.kg−1 dw soil) in the exchangeable fraction F1 (extraction with MgCl2) by comparison with the non-bioaugmented soil where neither Cr nor Pb was detected. Conversely, immobilization of Cr and
Pb in the soil were observed with the other microorganisms. The soil bioaugmentation not only modified the metal speciation
for the most easily extractable fractions but also modified the distribution of metals in the other fractions, to a lesser
extent nevertheless. The difference in microbial concentrations between the bioaugmented or not HC soils reached up to 1.8
log units. Thus the microorganisms that we chose for the soil bioaugmentation were competitive towards the indigenous microflora.
The PCA analysis showed close positive relationships between the microorganisms which potentially produced siderophores in
the soil and the amount of Cr and Pb in the fraction F1. 相似文献

Microsporidia parasites are commonly found in amphipods, where they are often asymptomatic, vertically-transmitted and have several effects on host sexuality and behaviour. As amphipods are often used as models in ecotoxicological studies, we investigated the effect of microsporidian infections on energy reserves and defence capacities of Gammarus roeseli under cadmium stress. Only females were infected by two microsporidia parasites: Dictyocoela roeselum or Dictyocoela muelleri. In physiological conditions, microsporidia had no major effect on energy reserves and defence capacities of G.?roeseli, while under cadmium exposure, energy reserves and antioxidant defence were weaker in infected females. Moreover, higher malondialdehyde levels detected in infected females revealed that they suffered more cellular damages. Our results suggest that microsporidia may affect gammarid fitness in stressful conditions, when parasitic stress cannot be compensated by the host. Consequently, microsporidia parasites should be a factor necessary to take into account in ecotoxicology studies involving amphipods. 相似文献
