Meanwhile, dMφs promoted the releasing of RANKL on DSCs after co-culture. Consistently, dMφs exhibited the lessoned capacity of adhesion to DSCs when blocking the crosstalk of RANKL-RANK between the DSCs and dMφs in vitro.

These results suggest that the interaction of RANKL-RANK up-regulates the expression of adhesion molecules on the surface of dMφs, contributing to the accumulation and residence of dMφs in human early pregnancy.

The objective of this study was to characterize lactic acid bacteria (LAB) from rabbits to be used as potential autochthonous probiotic.

Fifteen faecal samples were collected from wild and laboratory rabbits. One hundred and eight isolates were collected and tested for their inhibitory power against eight pathogenic bacteria. Among them, 43 Enterococcus isolates were able to inhibit at least one pathogen. Enterocine genes entA, entB and entP were detected in 14, 17 and 22 isolates, respectively. These isolates were tested for their antibiotic susceptibility and genes encoding virulence factors. Relevant phenotypes of antibiotic resistance were observed especially for ampicillin, vancomycin and linezolid. The following virulence genes were detected (number of positive isolates) hyl (5), esp (8), gelE (30), agg (2), ace (21), efa (6), CylL

(5), cob (26), cpd (32) and ccf (33). Five isolates were considered as safe and showed tolerance to both acid and bile salt.

Bacteriocinogenic enterococci isolates from rabbits may show relevant resistance phenotypes and virulence factors. In addition, one Enterococcus durans isolate presents promising autochthonous probiotic candidate.

This study reveals interesting properties for E.durans isolate and supports their utilization as autochthonous probiotic in rabbit husbandry.

Herein, we studied cation adduction and fragmentation of small metabolites by a combination of theoretical and experimental approaches, via nanoparticle-assisted laser desorption/ionization (LDI)-MS and MS/MS. We calculated the energies of adduction conformers and atomic bond orders to establish the rules of cation-metabolite affinity and multiple cation adductions in charge transfer. 5-aza-CdR Further, we demonstrated the reaction paths of adducted ions and mapped the potential energy surfaces to characterize the loss of given groups during fragmentation. Finally, we successfully controlled metabolite fragmentation by selected and multiple adductions to enhance the atomic/fragment coverage as defined for metabolite identification toward profiling. Considering the success of MS in the analysis of large biomolecules, our work may have an impact and guide to advanced analysis of small metabolites.Inflammation and oxidative stress play a key role in the pathophysiology of sickle cell disease (SCD). However, the potential influence of different sickle genotypes, or hydroxyurea (HU) treatment, on these factors remains poorly documented. The present study compared several plasma markers of inflammation and oxidative stress, as well as microvascular function, between patients with sickle SC disease (HbSC, n = 19) and patients with sickle cell anemia (HbSS) under hydroxyurea (HU) treatment (n = 16), or not (n = 13). Hemorheological parameters and levels of inflammatory (IL-6, IL-8, IFN-γ, MCP-1, MIP-1β, TNF-α) and oxidative stress (AOPP, MDA, MPO) markers were determined. Peripheral microcirculatory cutaneous blood flow and immediate microvascular response to local heat were evaluated using laser Doppler flowmetry. Oxidative stress and inflammation were lower in HbSC patients and HbSS patients under HU therapy compared to HbSS patients not treated with HU. Blood viscosity was higher in HbSC than in HbSS patients treated with or not with HU. Vasodilation response of the cutaneous microcirculation to heat stress was higher in HbSS patients receiving HU treatment. Our results clearly established that both sickle cell genotype and HU treatment modulate inflammation and oxidative stress.

Magnetic resonance (MRI) scanning of the heart is an established part of the investigation of cardiovascular conditions in children. In young children, sedation is likely to be needed, and multiple controlled periods of apnea are often required to allow image acquisition. Suppression of spontaneous ventilation is possible with remifentanil; however, the dose required is uncertain.

To establish the dose of remifentanil, by infusion, required to suppress ventilation sufficiently to allow a 30-s apnea during MRI imaging of the heart.

Patients aged 1-6years were exposed to different doses of remifentanil, and the success in achieving a 30-s apnea was recorded. A dose recommendation was made for each patient, informed by responses of previous patients using an adaptive Bayesian dose-escalation design. Other aspects of anesthesia were standardized. A final estimate of the dose needed to achieve a successful outcome in 80% of patients (ED80) was made using logistic regression.

38 patients were recruited, and apnea achieved in 31 patients. The estimate of the ED80 was 0.184µg/kg/min (95% CI 0.178-0.190). Post hoc analysis revealed that higher doses were required in younger patients.

The ED80 for this indication was 0.184µg/kg/min (95% CI 0.178-0.190). This is different from optimal dosing identified for other indications and dosing of remifentanil should be specific to the clinical context in which it is used.
