RNA interference (RNAi) is a sequence-specific gene silencing mechanism. It is induced by the formation of dsRNA that are recognised by the Dicer complex and processed into 21-23 long oligonucleotides called siRNA (short interfering RNA). Subsequently, RISC (RNA-Inducing Silencing Complex) binds siRNA that targets the complex towards its homologous mRNA (DYKXHOORN et al., 2003) which is eventually degraded. In contrast to budding yeast, the entire pathway is conserved in the fission yeast Schizosaccharomyces pombe, making it a valuable organism to both study physiological RNAi and to use it as a inducible gene knock-down tool. In an attempt to apply this method in the fission yeast, we are using three different approaches to produce siRNA. In each case, a vector containing a regulatable promoter activated in presence of tetracycline (tTA') (GOSSEN et al., 1995) is generated and the ura4 marker required for growth on medium lacking uracil serves as reporter. First, a vector expressing the full lenght antisens RNA of ura4 (800 nucleotides) (RAPONI and ARNDT, 2003) is used. Second, we are trying to generate much shorter dsRNA where both strands are linked by either a short hairpin of 25 nucleotides (BRUMMELKAMP et al., 2002) or a longer one of 350 nucleotides (SCHRAMKE and ALLSHIRE, 2003). The ability of these different dsRNA to induce silencing of ura4 will be presented. [less ▲]

Numerous experiments to date have demonstrated that elevated PCO2 is detrimental to biogenic calcification rates. However, most of these experiments have been realized in batch or continuous cultures and give little information on the dynamics of calcification in natural conditions. The present work describes the development and decay of a nutrient-induced bloom of the coccolithophorid Emiliania huxleyi in a mesocosm experiment. The monitoring of Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TAlk) within the seawater enclosures allowed us to describe comprehensively day to day dynamics of both calcification and organic carbon production. Three atmospheric PCO2 conditions (glacial, present and next century) were simulated by bubbling CO2 mixtures, while total alkalinity was left to evolve from its present value. No conspicuous change of Net Community Production under elevated PCO2 was recorded while the production of inorganic carbon appeared to be affected in two ways. Firstly, the production rate of inorganic carbon appeared to be lowered by 40% in the next century PCO2 conditions, decreasing concomitantly the calcification to photosynthesis ratio from 0.75 (glacial conditions) to 0.45 (next century conditions). Secondly, the onset of calcification was delayed by 24~48h under elevated PCO2 conditions, reducing the overall length of calcification in the course of the bloom. These two effects would act to reduce the amount of precipitated CaCO3 by coccolithophorids in a High CO2 world [less ▲]

The production of organic matter and calcium carbonate by a population of the brittle star Acrocnida brachiata (Echinodermata) was calculated using demographic structure, population density, and relations between the size and the ash-free dry weight (AFDW) or the calcimass. During a two-year survey in the Bay of Seine (English Channel, France), one of the four major estuaries affecting the biogeochemical cycling of elements in the southern bight of the North Sea, benthic production of this species amounted to 40.3 g.m-2.yr-1 for AFDW and 80.0 g.m-2.yr-1 for CaCO3. Respiration, based on secondary production, was estimated to be 736 mmol CO2.m-2.yr-1. Using the molar ratio () of CO2 released to CaCO3 precipitated, this biogenic precipitation of calcium carbonate would result in an additional release of 617 mmol CO2.m-2.yr-1. The results of the present study demonstrate that marine calcification should be considered as a significant source of CO2 to seawater and thus a potential source of CO2 to the atmosphere, emphasizing the important role of the biomineralization and dissolution in the carbon budget of temperate coastal ecosystems. This additional biogenic source of CO2 could increase in the future in two ways: firstly, as a positive feedback of  to the rising pCO2 and, secondly, as a positive response to the availability of nutrients due to eutrophication.

This Marie-Curie project integrates in the research framework of transport pathway and impact of pollutant studies in the marine ecosystem and aims to understand the effects of some pollutants on the general health status, the endocrine and immune systems of the harbour porpoise (Phocoena phocoena). Pollutants such as trace metals, or organochlorines which have been recognised to have endocrine or immune disrupting effects on other species will be examined. These investigations will examine if some endocrine and immune functions are impaired by those pollutants to the extend that harbour porpoises are susceptible to infectious agents which may decrease the population size.

More than 21,500 harbour seals were killed by Phocine Distempter Virus in the North Sea and adjacent waters in 2002. Of those more than 3,340 seals were found dead on the coast of Schleswig-Holstein. After the second seal die-off had ceased, seals were captured alive for a health check and also stranded seals were examined for their health status. Blood status and chemistry tests were performed, microbiological, parasitological, histological, serological and cytological investigations were conducted. During the first catch after the seal die-off animals seemed to be in clinically good condition although hematological disturbances (leucocytosis as well as leucopenia) were detected. Bacteriologically, Bordetella bronchisptica was isolated, a bacterium which was exclusively cultured during the seal die-off. At later catches hematological values normalized and also the normal bacterial flora was cultured from vagina and anus. The serological investigations for morbillivirus-specific antibodies revealed positive titers in 100% of the seals. Morphologically, there was no evidence for a continuing morbillivirus infection by both, histology and immunocytochemistry. The pathomorphological changes were similar to those before the epizootic including the predominance of parasitic and bacterial bronchopneumonia, emaciation and dermatitis. Contrary to the first seal die-off in 1988/89 an increased number of large skin wounds on the ventral side and infections of the umbilicus were not seen. This may indicate that the seal population in Schleswig-Holstein was generally in better health condition at the second seal die-off compared to the first one. The continued investigations will allow a further assessment of the development of the seal population in the Wadden Sea. [less ▲]

Until now, little attention has been paid to the processes controlling the production, dissolution and fate of biogenic calcium carbonate in the oceans. It is however well known that net deposition rates of inorganic carbon to the sediments are comparable to those of organic matter. There remains still large uncertainties concerning the production and redissolution of biogenic carbonate in the marine system and thus about the role of the carbonate pump in response to anthropogenic CO2 perturbations. The understanding of these processes is also a prerequisite to predict the response of marine organisms to global environmental changes. In the framework of the Belgian global change programme, we have developed a project devoted to the study of the inorganic carbon cycle in the Bay of Biscay where coccolithophorid blooms occur frequently. The study focuses on processes associated with the oceanic production and dissolution of calcium carbonate, by combining field investigations, laboratory experiments and modelling efforts. Remote sensing demonstrates a close relationship between vertical mixing along the continental margin and the development of the phytoplankton bloom. We will present here, results of 14C incorporation experiments used to evaluate the rate of production of organic and inorganic particulate carbon, obtained during a coccolithophorid spring bloom in the investigated area. A tentative mass balance of the carbon fluxes for this area will be presented, confirming the importance that the calcium carbonate pump may play in the oceanic system. [less ▲]

DBP reduction in the last 6 h of the once-daily dosing interval and 24-h mean DBP control when a dose is missed are significantly superior with telmisartan than with valsartan. Thus, telmisartan due to its longer half-life offers more sustained BP control, especially at the end of the dosing period and provides sustained efficacy in poorly compliant patients. [less ▲]

After ingestion of moulded beet pulp silage, cases of cortico-cerebral necrosis (CCN) and mortalities have been observed in a Belgian Blue (BB) herd. Contamination with Paecilomyces spp., a mould that produces byssochlamic acid, malformins and patulin, has been proven. Among these toxins, patulin is known to have cancerogenic, immunosuppressive and tremorgenic effects, but also acts on the respiratory and digestive systems. Twenty-five days after progressive introduction of beet pulp silage into the ration of a dual purpose BB herd, most of the animals showed diminished appetite, salivation and decreased milk production. All 35 cows were reluctant to consume the beet pulp silage, but continued to eat grass silage voluntarily. Seven of them showed anorexia and nervous symptoms, like head pressing and blindness. Four animals died within 1 week after onset of neurological symptoms. No necropsy has been performed, since legislation does not allow post-mortem examination of the central nervous system in the field. The three survivors had been treated successfully with thiamine (10 mg/kg, IV, TID) and recovered completely within five days. After the beet pulp silage had been identified as causative agent, it had been removed from the animals’ ration and no more clinical case has been observed. Four weeks later, the same beet pulp silage has been reintroduced into the animals’ ration and provoked again diminished appetite, salivation and a decrease in milk production in most of the animals. Clinical signs were also suggesting lead poisoning but any contact with lead containing material could have been excluded. Silage was obviously moulded and analysis revealed the presence of 1.6 million CFU Paecilomyces spp./g of silage. Although no further investigation has been made to identify the mycotoxins, an intoxication with patulin has been suspected, since other mycotoxins produced by these species are less toxic. Although it has not been described that CCN can be induced by ingestion of Paecilomyces spp., it seems that there is a close relation between ingestion of Paecilomyces-contaminated silage and observed clinical signs in this herd.

In Belgium, respiratory distress syndrome (RDS) is one of the leading causes of neonatal death in the mature hypermuscled Belgian Blue calf (BB) but also occurs in other cattle breeds. Major clinical signs (tachypnea, tachycardia and sometimes depression) develop in the first hours after birth and are due to insufficiency of functional surfactant. Knowing that trace elements deficiencies can slow pulmonary maturation, the aim of this study was to investigate trace elements status in 10 RDS affected BB herds in comparison with 6 reference herds without any evidence of RDS. In each herd, blood was sampled from 10 pregnant or freshly calved healthy cows. In each blood sample, the plasmatic zinc (Zn) and copper (Cu) contents and erythrocytic glutathion peroxydase activity (GSH-pxe) were measured and considered normal when above 15 μmol/L, 14 μmol/L and 250 IU/gHb, respectively. A herd was deficient in one element if at least 30 % of sampled animals were out of normal range for this element. Milk was also sampled and pooled from 10 other cows or, when possible, bulk milk was taken. Milk iodine (I) content was considered normal when above 80 μg/L. Results were compared between groups by Chi-square test. All RDS affected herds had low Zn and Cu concentrations and low GSH-pxe activity. Eight out of 10 had low I in milk. In the non-RDS affected herds, only 1 herd was deficient in I, Zn, Cu and had low GSH-pxe activity, 2 herds were deficient in Zn and Cu and 1 herd was deficient in Cu. RDS affected herds were significantly more often deficient in I and GSH-pxe than non-affected herds. It seems that the trace elements selenium (Se), Zn and Cu play an essential role in the development of RDS. The same applies for I, although not deficient in all herds. The reason for this might be that milk samples were taken during lactation, when cows’ nutrition was different and, in any case, supplemented in I. In mature babies, the same RDS is observed but its etiology is still unclear, although I deficiency in the mother is suspected to play a major role in pathogenesis. Furthermore, it has been demonstrated that a Se-dependent deiodinase is responsible for transformation of thyroxine (T4) into tri-iodothyronine (T3), which is essential for effective surfactant production. In conclusion, results suggest an association between RDS in mature newborn calves and trace elements deficiencies, especially Se and I, that can be responsible for primary surfactant insufficiency.

Jovian X-rays can be broadly classified into two categories: (1) "auroral" emission, which is confined to high-latitudes ( ˜>60° ) at both polar regions, and (2) "dayglow" emission, which originates from the sunlit low-latitude ( ˜<50° ) regions of the disk (hereafter called "disk" emissions). Recent X-ray observations of Jupiter by Chandra and XMM-Newton have shown that these two types of X-ray emission from Jupiter have different morphological, temporal, and spectral characteristics. In particular: 1) contrary to the auroral X-rays, which are concentrated in a spot in the north and in a band that runs half-way across the planet in the south, the low-latitude X-ray disk is almost uniform; 2) unlike the ˜40±20-min periodic oscillations seen in the auroral X-ray emissions, the disk emissions do not show any periodic oscillations; 3) the disk emission is harder and extends to higher energies than the auroral spectrum; and 4) the disk X-ray emission show time variability similar to that seen in solar X-rays. These differences and features imply that the processes producing X-rays are different at these two latitude regions on Jupiter. We will present the details of these and other features that suggest the differences between these two classes of X-ray emissions from Jupiter, and discuss the current scenario of the production mechanism of them.

Background Low frequency (<0.1Hz) fluctuations originating from blood flow and oxygenation have been observed in the brain by different groups (Golanov et al. 1994; Biswal.et al. 1995). The goal of this study was to use BOLD fMRI to characterize coherent fluctuations in those low frequencies between spatially distant brain regions. Methods Thirteen right-handed subjects were studied using blocked-design BOLD fMRI at rest and as they performed sequential finger movements at a slow rate (~0.5 Hz) with their right hand. Serial acquisitions of EPI images were obtained at 3T using a single-shot 2D gradient-echo echo-planar imaging sequence. Data were processed and analyzed using standard procedures implemented in the statistical parametric mapping software (SPM2). Temporal profile of brain activity in 6 predefined regions (left S1M1, right S1M1, SMA, left thalamus, right cerebellum and CSF) were extracted on a subject-by-subject basis using the VOI tool in SPM2. After deconvolution (Gitelman et al. 2003), time series data representing movement and resting conditions were concatenated to create 2 within-condition time-series. After subtracting the mean over all epochs from each epoch, the (complex) coherency was calculated in the 5 lowest frequency bins with a frequency resolution of 1/17.5Hz (0, 0.05, 0.11, 0.17, 0.23 Hz). Real and imaginary parts of coherency, representing correlation and correlation of phase-shifted signals, respectively, were analyzed separately. Coherency was computed independently for each region pairs and each subject. Significance was defined as p<0.05 Bonferroni corrected for multiple comparisons. Results The main finding was the presence of coherent fluctuations in BOLD signal mainly in the lowest frequencies for (almost) all regions. The real part of coherency was equally pronounced during the movement and rest conditions. The only exception was a larger coherence during rest than during the task condition in the lowest frequencies between left and right S1M1. We could not find any significant imaginary part of coherency indicating that the time delays between dependent neural activations are negligible compared to the inverse frequencies under study. Partialling out the data in any of the regions did not have any significant impact on coherence map. Importantly, there was no evidence of coherent activity between any of the brain regions and CSF in any of the frequency bands. Discussion BOLD signal recorded during different behavioral steady-states showed very similar coherent fluctuations for all regions pairs studied mainly in the lowest frequencies. Those results are in good agreement with electrophysiological recordings in monkeys in which high coherence in band-limited power of local field potential signals have been reported at very low frequencies (<0.1Hz) (Leopold et al. 2003). In that study, coherence patterns were also highly similar under distinctly different behavioral states. Task-independent coherence in lower frequencies may be related to whole brain slow synchronous oscillations whose significance remains to be elucidated. References Golanov et al. (1994).

Introduction and Objective: To describe a new, simple surgical technique for the treatment of female stress urinary incontinence (SUI) and to evaluate its feasibility. Methods: We have developed a novel surgical treatment of SUI, the transobturator inside-out tension-free urethral suspension, which uses specifically designed surgical tools: a pair of stainless steel helical passers, two plastic tubes with a pointed distal end and one guide. Using these instruments, a synthetic tape is passed from underneath the urethra, through the obturator foramens, towards the thighs, without entering the pelvic region at any time during the procedure. The tubes bear a lateral opening, which allows the insertion of the helical passer into its lumen. The proximal end of each tube is attached to a non-absorbable synthetic tape. The guide acts as a shoe-horn to ease the introduction of the tubes assembled onto the helical passers from the perineal space through the obturator foramen. After perforation of the obturator membrane, a rotational movement of the helical passer around the upper part of ischio-pubic ramus allows the exit of the pointed tip of the tube and, further, of the tape at the level of the thigh on either side. The tape is positioned without tension under the junction between mid and distal urethra. Results: The procedure was carried out in 210 consecutive patients (mean age = 62 years) using the same operative protocol in all case subjects, independently of the patient’s size and weight. Mean operative time was 14 min (range = 6 to 20) in case of isolated SUI treatment. No bladder or urethra injury and no vascular (hematoma or bleeding) or neurological complication were observed. Conclusions: The results of this study indicate that our novel transobturator inside-out surgical technique for treating SUI is feasible, accurate, and quick. This technique avoids damage to the urethra and bladder and, therefore, makes cystoscopy not necessary. Further prospective studies are currently ongoing to determine the efficacy of our new surgical approach for treating SUI. [less ▲]
