miR-155−/− and WT mice received 1 × 105 PFU of CVB3 or PBS i.p. on day 0 and the heart samples were isolated on day 7. (A) miR-155 expression was determined by real-time PCR in hearts or heart infiltrating cells from CVB3 or PBS injected WT mice. (B) Heart sections of CVB3-infected WT and miR-155−/− KO mice were stained with H&E, and the severity of myocarditis was assessed as the percentage of the heart section with inflammation compared with the overall size of the heart section, with the aid of a microscope eyepiece grid. Scale bar = 100 μm. (C) Myocardial infiltration of CD45+ cells was determined by FACS. (D) Viral titers were measured using plaque assay. Experiments were repeated three times in triplicate with 8 mice per group. Bar graph data are presented as mean ± SD; *P < 0.05 and **P < 0.01 as compared with WT. WT: wildtype mice; KO: knockout mice; NS: no significance. Similar data presentation will appear in the subsequent figures.

Quantitative sputum cell counts from patients with asthma and chronic bronchitis were performed and found to be reproducible. Sputum from carefully characterized subjects with asthma contained large numbers of eosinophils and formalin-sensitive metachromatic (mast) cells. In contrast, the macrophage was the dominant cell type in the sputum from smokers with chronic bronchitis. In a third group of patients with corticosteroid responsive-chronic cough and normal methacholine airway responsiveness the sputum contained eosinophils and metachromatic cells, similar to the asthmatic subjects. Sputum cell counts are a useful, noninvasive method for the identification of this pattern of inflammatory response in patients with airway diseases.

ONX 0914 treated mice displayed a higher susceptibility to systemic candidiasis compared to vehicle treated control mice which, unexpectedly, manifested at very early stages of infection. We observed a more pronounced weight loss, an impaired survival, and a higher fungal burden of the kidney and the brain (Figs 3B,C and 4A,B). Interestingly, mice lacking immunoproteasome subunits LMP2, MECL-1, or LMP7 showed no difference in weight loss (Fig. 3A) or survival (data not shown) compared to WT mice. The difference between LMP7−/− and ONX 0914 treated mice might be explained by structural changes in the immunoproteasome when LMP7 is absent and replaced by its constitutive counterpart β5 which maintains the chymotrypsin-like activity in immunoproteasomes of LMP7−/− cells35. In contrast, when LMP7 is chemically inhibited with ONX 0914, the LMP7-dependent chymotrypsin-like activity of the immunoproteasome is irreversibly blocked. However, the influence of LMP7 inhibition became apparent far too early for impaired T helper cell differentiation being the reason for the increased susceptibility of ONX 0914 treated mice. In fact, adaptive immunity does not play a prominent role in combatting disseminated candidiasis. Instead, resistance to systemic C. albicans infection is mainly mediated by innate immune cells indicating that immunoproteasome inhibition has a more versatile effect on the anti-C. albicans immunity25,30,36.

Since the parties that comprise the GoI have offical positions based on the nonexistance of a Palestinian state (and actual state and not a bantustan) then it’s fair and reasonable to suggest that the GoI has no interest or vision in peace with the Palestinians. Right?

BACKGROUND: Lung volume reduction surgery (LVRS) has been re-introduced for treating patients with severe diffuse emphysema. OBJECTIVES: To assemble evidence from randomised controlled trials for the effectiveness of LVRS, and identify optimal surgical techniques, those patients who benefit most and those for whom it should be avoided. SEARCH STRATEGY: Randomised controlled trials were identified using the Cochrane Airways Group COPD register using the terms: emphysema AND (emphysema surgery OR lung volume reduction surgery OR LVRS OR volume reduction surgery OR pneumectomy OR reduction pneumoplasty OR lung reduction surgery). The Cochrane Controlled Clinical Trials Register was also searched using these terms. SELECTION CRITERIA: Randomised controlled trials that studied the safety and efficacy of LVRS in patients with diffuse emphysema were included. Studies were excluded if they investigated giant or bullous emphysema. DATA COLLECTION AND ANALYSIS: Two independent reviewers assessed trials for inclusion and extracted data. MAIN RESULTS: Only one randomised trial of LVRS for diffuse emphysema was identified. This compared stapled unilateral thoracoscopic lung reduction coupled with bovine pericardium reinforcement with a unilateral neodymium:yttrium aluminium garnet laser contact reduction. A total of 72 patients were studied. Both arms included post-operative rehabilitation and appeared to be well matched at randomisation. Improvement in FEV1 & FVC at six months was significantly greater in the staple treated group (p < 0.01 & p < 0. 07 respectively), but absolute increases were small. Need for supplemental oxygen was reduced significantly more in the staple treated group; Peto Odds Ratio (OR) 4.05; 95% confidence interval (CI) 1.40, 11.71. Quality of life improved more in the staple treated group (OR 5.36; 95% CI 2.13,13.47). The rate of delayed pneumothorax in the laser treated group was significantly higher (OR 10.46; 95% CI 1.98, 55.30). REVIEWER’S CONCLUSIONS: There is no randomised controlled trial evidence concerning the efficacy of LVRS for diffuse emphysema compared to optimal conservative medical therapy. Stapling is more effective than laser resection and has a lower complication rate. LVRS should not be applied routinely until results of large trials currently underway become available.

This study investigates the molecular mechanisms driving airway neutrophilia following a high fat meal in asthmatics. Subjects with asthma (n = 11) and healthy controls (n = 8) consumed a high-fat/energy meal, containing total energy (TE) of 3846 kJ and 48 g of total fat (20.5 g saturated). Sputum was induced at 0 and 4 h, and gene expression was examined by microarray and quantitative real-time PCR (qPCR). Following the high fat dietary challenge, 168 entities were significantly differentially expressed greater than >1.5 fold in subjects with asthma, whereas, in healthy controls, only 14 entities were differentially expressed. Of the 168 genes that were changed in asthma, several biological processes were overrepresented, with 25 genes involved in "immune system processes". qPCR confirmed that S100P, S100A16, MAL and MUC1 were significantly increased in the asthma group post-meal. We also observed a strong correlation and a moderate correlation between the change in NLRP12 and S100A16 gene expression at 4 h compared to baseline, and the change in total and saturated non-esterified plasma fatty acid levels at 2 h compared to baseline. In summary, our data identifies differences in inflammatory gene expression that may contribute to increased airway neutrophilia following a high fat meal in subjects with asthma and may provide useful therapeutic targets for immunomodulation. This may be particularly relevant to obese asthmatics, who are habitually consuming diets with a high fat content.
