5 ± 2.7vs. 4.9 ± 3.1g, P=.001). The impedance drop for each lesion was larger in the visualized sheath group than conventional sheath group (10.7 ± 6.5vs. 9.8 ± 5.5 ohms, P<.001). The incidence of acute PV reconnections per patient (30%vs. 23%, P=.56) and per PV segment (2.5%vs. 2.3%, P=.83) were similar between the two groups. No major complications occurred in either sheath group. The use of visualized sheaths may reduce the fluoroscopic time and improve the catheter stability during the PVI.The use of visualized sheaths may reduce the fluoroscopic time and improve the catheter stability during the PVI. Elevated plasma concentrations of syndecan-1 and heparan sulfate in studies of trauma, sepsis, and major surgery are commonly assumed to indicate acute glycocalyx degradation. We explored a possible role of the kidneys for these elevations. Plasma and urine concentrations of syndecan-1, heparan sulfate, and biomarkers of inflammation were measured over 5hours in 15 hospital patients treated for post-burn injury. check details The renal clearances of syndecan-1 and heparan sulfate (CL ) were calculated and their influence on the plasma concentration predicted by simulation. The urine/plasma concentration ratio was 0.9 (0.3-3.0) for syndecan-1 and 2.8 (2.0-4.3) for heparan sulfate. The CL varied 250-fold for syndecan-1 and 10-fold for heparan sulfate. Multiple linear regression analysis showed that CL for syndecan-1 was positively associated with the creatinine clearance (P<.0032) and the urine flow (P<.015). CL for heparan sulfate increased with interleukin-6 (P<.003) and the urine flow (P<.01). Simulations suggested that a change in CL from the mean of the highest 3 to the lowest three values would double plasma syndecan-1 within 4hours and cause a 7-fold rise after 24hours. A similar change in CL for heparan sulfate would triple the plasma level within 24hours, even if no increased shedding of the glycocalyx takes place. The renal elimination of syndecan-1 and heparan sulfate varied greatly. A change in kidney function, which is common after trauma and major surgery, might alone induce several-fold changes in their plasma concentrations.The renal elimination of syndecan-1 and heparan sulfate varied greatly.

Recent biochemical and pharmacological studies have reported that in several tissues and cell types, microsomal PGE synthase (mPGES) and PPAR-γ expression are modulated by a variety of inflammatory factors and stimuli. Considering that very little is known about the biological effects promoted by IL-17 in the context of mPGES-1/PPAR-γ modulation, we sought to investigate the contribution of this unique cytokine on this integrated pathway during the onset of inflammation. We evaluated effects of PF 9184 (mPGES-1 inhibitor) and troglitazone (PPAR-γ agonist) in vitro, using the mouse macrophage cell line J774A.1. In vivo, the dorsal air pouch model in CD1 mice was used, and inflammatory infiltrates were analysed by flow cytometry. Locally produced cyto-chemokines and PGs were assessed using elisa assays. Western blots were also employed to determine the activity of various enzymes involved in downstream signalling pathways. PF 9184 and troglitazone, in a time- and dose-dependent manner, modulated leukocyley.com/doi/10.1111/bph.v179.9/issuetoc.Autoimmune hepatitis (AIH) is an immune-mediated inflammatory liver disease for which the pathogenesis remains incompletely understood. The current study aimed to reveal key biological processes and immune cells implicated in AIH by integrated bioinformatic analysis. The global gene expression in livers from wild-type BALB/c mice, mice with Tgfb1 deficiency, and mice with both Tgfb1 and Ifng deficiency was assessed by microarray data analysis. Differentially expressed genes were identified and subjected to functional enrichment analysis. AIH mice with Tgfb1 deletion showed significantly enhanced immune responses but impaired metabolic processes, whereas increased T cell activation and cytokine production, but weakened organic acid and lipid metabolic processes were observed in mice with deletion of both Tgfb1 and Ifng. In addition, infiltration of immune cells was evaluated by CIBERSORT. Increased infiltration of T cells, macrophages, and natural killer cells, and decreased infiltration of neutrophils, eosinophils, plasma cells, and B cells were observed in AIH mice. In conclusion, we identified potential biological processes and immune cells that contributed to AIH; further investigations are needed to confirm these findings and thus provide a potential novel therapeutic target for AIH treatment. The trajectory, magnitude and localisation of metabolic perturbations caused by immobilisation (IMM) are unresolved. Forearm glucose uptake (FGU) in response to glucose feeding was determined in healthy men before and during 72h of forearm IMM, and the same measurements were made in the non-IMM contralateral limb at baseline and 72h. In a similar study design, FGU and forearm lipid uptake were determined after a high fat mixed-meal (HFMM) in IMM and non-IMM limbs. FGU was reduced by 38%, 57% and 46% following 24, 48 and 72h IMM, respectively, but was unchanged in the non-IMM limb. A similar FGU response to IMM was observed after a HFMM, and forearm lipid uptake was unchanged. A sizeable reduction in FGU occurs in just 24h of IMM, which is sustained thereafter and specific to the IMM limb, making unloading per se the likely rapid driver of dysregulation. The trajectory and magnitude of metabolic perturbations caused by muscle disuse are unknown yet central to understanding the mechanistic basis of immobili-immobilised limb at 72 h (P = 0.002). In a second study, FGU and forearm lipid uptake were determined in nine healthy men (age 22.4 ± 1.3 years, weight 71.4 ± 2.8 kg, BMI 22.6 ± 0.8 kg/m2 ) during a 420 min mixed-meal challenge before (0) and after 24 and 48 h of arm immobilisation and before and after 72 h in the contralateral non-immobilised arm (Study B). FGU responses were similar to Study A, and forearm lipid uptake was unchanged from pre-immobilisation in both arms over the study. A sizeable decrement in FGU in response to glucose feeding occurred within 24 h of immobilisation that was sustained and specific to the immobilised limb. Increasing lipid availability had no additional impact on the rate or magnitude of these responses or on lipid uptake. These findings highlight a lack of muscle contraction per se as a fast-acting physiological insult to FGU.
