We report the identification of 61.45 d[SUP]-1[/SUP] (711.2 μHz) oscillations, with amplitudes of 62.6 μmag, in KIC 4768731 (HD 225914) using Kepler photometry. This relatively bright (V = 9.17) chemically peculiar star with spectral type A5 Vp SrCr(Eu) has previously been found to exhibit rotational modulation with a period of 5.21 d. Fourier analysis reveals a simple dipole pulsator with an amplitude that has remained stable over a 4-yr time span, but with a frequency that is variable. Analysis of high-resolution spectra yields stellar parameters of T[SUB]eff[/SUB] = 8100 ± 200 K, log g = 4.0 ± 0.2, [Fe/H] = +0.31 ± 0.24 and v sin i = 14.8 ± 1.6 km s[SUP]-1[/SUP]. Line profile variations caused by rotation are also evident. Lines of Sr, Cr, Eu, Mg and Si are strongest when the star is brightest, while Y and Ba vary in antiphase with the other elements. The abundances of rare earth elements are only modestly enhanced compared to other roAp stars of similar T[SUB]eff[/SUB] and log g. Radial velocities in the literature suggest a significant change over the past 30 yr, but the radial velocities presented here show no significant change over a period of 4 yr. [less ▲]

The paper provides an introductory discussion about two fundamental models of oscillator synchronization: the (continuous-time) diffusive model, that dominates the mathematical literature on synchronization, and the (hybrid) kick model, that accounts for most popular examples of synchronization, but for which only few theoretical results exist. The paper stresses fundamental differences between the two models, such as the different contraction measures underlying the analysis, as well as important analogies that can be drawn in the limit of weak coupling.

Pancreas Transplantation aims at providing Beta cells replacement in diabetic patients, especially for type 1 diabetes recipients in whom Beta cells had been destroyed by an autoimmune process. The final achievement is to restore a normal physiological control of glucose metabolism in order to halt or reverse the secondary complications of diabetes i.e. retinopathy, neuropathy, nephropathy, micro – and macro - angiopathy [1]. That can be achieved by a vascularised pancreas graft (referred as Pancreas Transplantation, PT) or by islet grafting (referred as Islet Transplantation, IT). The former PT includes transplanting 95% of unuseful cells, the exocrine part from one pancreas, while the last one IP, embolizing into the recipient liver, Islets of Langerhans after digestion and purification of several human pancreases. Three types of PT can be performed: the pancreas and a kidney are simultaneously transplanted with a single induction of immunosuppression (IS) therapy in hoping to correct both uremia and diabetes mellitus (SPK = Simultaneous Pancreas and Kidney Transplantation); the pancreas is transplanted after a successful kidney graft allowing two induction therapies along with the basic IS treatment (PAK = Pancreas After Kidney Transplantation) ; and finally the Pancreas can be transplanted alone in pre-uremic recipients with unawareness hypoglycaemic events or with rapidly evolving secondary complications of diabetes such as proliferative retinopathy, or advanced neuropathy (PTA = Pancreas Transplantation Alone) [1]. Moreover, in SPK, both organs the Pancreas and the Kidney are procured from the same deceased donor, either donor after brain death (DBD) or donor after cardiac death (DCD). In some US institutions, a segmental pancreas and the left kidney, are procured in a living donor [2], using a laparoscopic approach in the more recent year [3]. For PAK, in order to avoid an excessive IS load and two induction therapies, other institutions had proposed whenever possible to keep in stand-by the potential live kidney donor until a cadaver whole pancreatic compatible graft is available [1]. By contrast, the number of PTA remains limited in non uremic recipients with life-threatening complications of diabetes, in whom one might hope to avoid the hypoglycaemic events with a successful graft. That can also be achieved with IT. But except for rare cases, insulin independence with IT requires more than a single human pancreas and is limited over time [1]. Moreover, IT needs costly materials, chambers and rooms for preparation. That’s why IT will not be included in the present report. [less ▲]

Worldwide shortage of standard brain dead donors (DBD) has revived the use of kidneys donated after circulatory death (DCD). We reviewed the Belgian DCD kidney transplant (KT) experience since its reintroduction in 2000. Risk factors for delayed graft function (DGF) were identified using multivariate analysis. Five-year patient/graft survival was assessed using Kaplan–Meier curves. The evolution of the kidney donor type and the impact of DCDs on the total KT activity in Belgium were compared with the Netherlands. Between 2000 and 2009, 287 DCD KT were performed. Primary nonfunction occurred in 1% and DGF in 31%. Five-year patient and death-censored graft survival were 93% and 95%, respectively. In multivariate analysis, cold storage (versus machine perfusion), cold ischemic time, and histidine-tryptophan-ketoglutarate solution were independent risk factors for the development of DGF. Despite an increased number of DCD donations and transplantations, the total number of deceased KT did not increase significantly. This could suggest a shift from DBDs to DCDs. To increase KT activity, Belgium should further expand controlled DCD programs while simultaneously improve the identification of all potential DBDs and avoid their referral for donation as DCDs before brain death occurs. Furthermore, living donation remains underused. Transplant International ISSN 0934-0874 ª [less ▲]

High prevalence of the problem in part due to ageing with CKD - Consequences for the patient and the economy of health - Danger of CKD development or aggravation, mortality Need for early diagnosis (new biomarkers?) but not yet proof of efficacy for prevention. Useful for predicting prognosis? Prevention first: interval between contrast agents use and surgery, caution about medical therapy, fluid volume balance, importance of the kind of solution used, quality of the CBP! Treatment: avoid complications when AKI installed, nutrition ! Early RRT (?)(rapid uremic control or fluid balance?) but high mortality even after hospital discharge (max 1/3 survival at 1 y) [less ▲]

Acer negundo (boxelder maple) is a North American native tree species that currently invades riparian and disturbed areas in Europe, affecting both bank stability and ecosystem biodiversity. As a response to managers’ requests, we aimed at finding an eco-friendly method which would locally remove this species and help habitat restoration. Four control methods were tested on A. negundo adults and saplings from stands located in three experimental sites along different watercourses in Southwestern France: girdling, low cutting, high cutting, and cutting followed by the application of juglone (a natural allelopathic substance from walnut tree leaves). Mortality and resprout production on the treated A. negundo individuals were assessed during two years following the application of the control methods. Girdling was the most efficient method as it significantly induced higher mortality rates compared to the others (65 vs 15% of dead A. negundo two years after treatment administration). When healing emerged on trunks, yearly repeated girdling was required to reach full success. None of the control methods significantly reduced resprout production; not even the application of juglone. Girdling is the most recommended method to kill and remove A. negundo at a local scale in invaded natural habitats. Considering that A. negundo benefits from increases in light availability to outcompete native species, we further recommend removing seedlings from understories when applying girdling on adult and sapling individuals in order to optimize restoration conditions in natural stands and improve native species re-establishment.

BACKGROUND: Associated with high morbidity and mortality, severe GBS infections should be treated with antimicrobial agents alone or in combination characterized by both a good diffusion at the site of infection and a short bactericidal lag time. Penicillin (P) or another blactam used in combination with an aminoglycoside is usually recommended to start the therapy. MICs to gentamicin (G) of GBS recently isolated in Belgium range from 16 to 256 mg/L (> or = MICs of E.faecalis with low level resistance to G, LLR). OBJECTIVES: To investigate in vitro, the potential synergism of P+G on strains of GBS isolated in Belgium. METHODS: According to Etest-AB Biodisk original procedures, for 6 Belgian strains of GBS (G MICs: 16-128 mg/L), we investigated the potential synergism, MICs and time killing curves, between P and G (ratio1:1). In the killing kinetic assays, surviving organisms were enumerated initially and repeatedly after 2, 4, 8 and 20 hours (T2, T4, T8 and T20) at concentrations of P equal to 4 and 16x MICs. Two strains of E.faecalis (1 HighLR and 1 LLR to G) were used as negative and positive control. Each isolate was tested twice. RESULTS: For GBS the P MICs in the combination were within +/- 1 dilution compared with single drug. As expected, P+G produced enhanced killing at T2 and T4 compared with P alone for G LLR E.faecalis and there was no difference for the G HLR E.faecalis. On the contrary, no accelerated killing was observed for any GBS isolate with the combination even for a concentration of 16xMIC of P; moreover for 3 isolates a reduced killing was observed at T2 in the combination tests compared with P alone. CONCLUSION: This limited in vitro testing of the combination P+G compared with P alone for Belgian GBS isolates did not show any synergism or accelerated killing. Moreover the killing was reduced at T2 for half of the isolates. Further evaluation should be performed on these strains with other ratio or other b-lactams as ampicillin in combination with G.
