A Case of Advanced Tubal Ectopic Pregnancy after Emergency Contraception
Ectopic pregnancy is a relatively common condition and an important cause of morbidity in women of childbearing age. The most frequent implantation site is the fallopian tube. Most cases are diagnosed in an early gestational period. Patients come to the attention of clinicians for pelvic pain and vaginal blood loss, and consequent diagnosis is made through clinical presentation, laboratory tests, and ultrasound. Other rarer implantation sites such as the abdominal cavity give space for ectopic pregnancy to grow until later gestational ages, delaying diagnosis. This is a rare case of a healthy 41-year-old woman with an advanced ectopic pregnancy after emergency contraception with Ulipristal Acetate. The patient went to visit for amenorrhea after taking a contraceptive. Evaluation with ultrasound demonstrated a 10 + 4 weeksâ unruptured tubal pregnancy with fetal heart rate. The patient underwent laparoscopic salpingectomy without complication. This is the first case of such an advanced ectopic pregnancy in a woman who performed emergency contraception with Ulipristal Acetate

The architecture of Phaseolus vulgaris root is altered when a defense response is elicited by an oligogalacturonide
Contribution of the Microbial Communities Detected on an Oil Painting on Canvas to Its Biodeterioration
In this study, we investigated the microbial community (bacteria and fungi) colonising an oil painting on canvas, which showed visible signs of biodeterioration. A combined strategy, comprising culture-dependent and -independent techniques, was selected. The results derived from the two techniques were disparate. Most of the isolated bacterial strains belonged to related species of the phylum Firmicutes, as Bacillus sp. and Paenisporosarcina sp., whereas the majority of the non-cultivable members of the bacterial community were shown to be related to species of the phylum Proteobacteria, as Stenotrophomonas sp. Fungal communities also showed discrepancies: the isolated fungal strains belonged to different genera of the order Eurotiales, as Penicillium and Eurotium, and the non-cultivable belonged to species of the order Pleosporales and Saccharomycetales. The cultivable microorganisms, which exhibited enzymatic activities related to the deterioration processes, were selected to evaluate their biodeteriorative potential on canvas paintings; namely Arthrobacter sp. as the representative bacterium and Penicillium sp. as the representative fungus. With this aim, a sample taken from the painting studied in this work was examined to determine the stratigraphic sequence of its cross-section. From this information, âmock paintings,â simulating the structure of the original painting, were prepared, inoculated with the selected bacterial and fungal strains, and subsequently examined by micro-Fourier Transform Infrared spectroscopy, in order to determine their potential susceptibility to microbial degradation. The FTIR-spectra revealed that neither Arthrobacter sp. nor Penicillium sp. alone, were able to induce chemical changes on the various materials used to prepare âmock paintings.â Only when inoculated together, could a synergistic effect on the FTIR-spectra be observed, in the form of a variation in band position on the spectrum.The FTIR analyses performed in this study were financed by the Junta de AndalucĂa (RNM-325 group).

Molecular Tools for Monitoring the Ecological Sustainability of a Stone Bio-Consolidation Treatment at the Royal Chapel, Granada
Background:
Biomineralization processes have recently been applied in situ to protect and consolidate decayed ornamental stone of the Royal Chapel in Granada (Spain). While this promising method has demonstrated its efficacy regarding strengthening of the stone, little is known about its ecological sustainability.Methodology/Principal Findings:
Here, we report molecular monitoring of the stone-autochthonous microbiota before and at 5, 12 and 30 months after the bio-consolidation treatment (medium/long-term monitoring), employing the well-known molecular strategy of DGGE analyses. Before the bio-consolidation treatment, the bacterial diversity showed the exclusive dominance of Actinobacteria (100%), which decreased in the community (44.2%) after 5 months, and Gamma-proteobacteria (30.24%) and Chloroflexi (25.56%) appeared. After 12 months, Gamma-proteobacteria vanished from the community and Cyanobacteria (22.1%) appeared and remained dominant after thirty months, when the microbiota consisted of Actinobacteria (42.2%) and Cyanobacteria (57.8%) only. Fungal diversity showed that the Ascomycota phylum was dominant before treatment (100%), while, after five months, Basidiomycota (6.38%) appeared on the stone, and vanished again after twelve months. Thirty months after the treatment, the fungal population started to stabilize and Ascomycota dominated on the stone (83.33%) once again. Members of green algae (Chlorophyta, Viridiplantae) appeared on the stone at 5, 12 and 30 months after the treatment and accounted for 4.25%, 84.77% and 16.77%, respectively.Conclusions:
The results clearly show that, although a temporary shift in the bacterial and fungal diversity was observed during the first five months, most probably promoted by the application of the bio-consolidation treatment, the microbiota tends to regain its initial stability in a few months. Thus, the treatment does not seem to have any negative side effects on the stone-autochthonous microbiota over that time. The molecular strategy employed here is suggested as an efficient monitoring tool to assess the impact on the stone-autochthonous microbiota of the application of biomineralization processes as a restoration/conservation procedure.This work was supported by the European Regional Development Fund (ERDF), Junta de AndalucĂa (Spain) and the âFortalecimiento de la I+D+iâ program from the University of Granada, co-financed by grant RNM-3493 and Research Group BIO-103 from Junta de AndalucĂa, as well as by the Spanish Government through âJosĂ© Castillejoâ program from the âMinisterio de EducaciĂłn, Cultura y Deporteâ (I+D+i 2008-2011), and by the Austrian Science Fund (FWF) under Grant âElise-Richter V194-B20â
Development of Means to Augment Peritoneal Urea Clearances: The Synergistic Effects of Combining High Dialysate Temperature and High Dialysate Flow Rates with Dextrose and Nitroprusside
By combining: a) nitroprusside (4.5 mg/L); b) dextrose concentration of 42.5 gm/L; c) dialysate temperature of 42°C and d) dialysate flow rates of 3.5 L/hour in seven uremic subjects on C APD, it was possible to increase peritoneal urea clearance up to 35.6 ± 3.8 ml/min/1.73 m2 (range 30.3 to 42.2). This effect in six out of seven cases was associated with a fall in blood pressure and an increase in heart rate. This study is the first which deals with a combination of these factors and demonstrates that this approach is easy to handle, does not require the use of mechanical devices, and is available at any bedside. © 1981 International Center for Artificial Organs and Transplantatio
The effect of atrial natriuretic factor on blood pressure and renal function of long-term hypothyroid rats
The present study demonstrates that a mild dose of ANF is able to induce natriuresis and diuresis in a model of long-term hypothyroid rats. That effect is mediated to a large extent by a sustained increase in GFR, although a tubular action cannot be excluded. Moreover, the large natriuresis and diuresis is not coupled to a decrease in systemic blood pressure. It is important to stress that, in other pathophysiological states (namely, the experimental acute renal failure induced either by norepinephrine or by cisplatin and in the chronic metabolic alkalosis) characterized by a reduced GFR, the principal mechanism underlying the natriuretic effect of ANF seems to be an increase in GFR
