© 2016 John Wiley & Sons Ltd. Background: Non-eosinophilic asthma (NEA) is a distinct, often corticosteroid-resistant inflammatory asthma phenotype. NK and NKT-like cells are effector lymphocytes that we have shown, like CD28null T cells, to be relatively resistant to steroids and major sources of pro-inflammatory/cytotoxic mediators. We hypothesized that these cells and mediators would be increased in peripheral blood in NEA. Methods: Adults with severe asthma and variable airflow obstruction, poorly controlled despite maintenance therapy with inhaled glucocorticosteroids and long-acting bronchodilators, were recruited. Blood was assessed in those with eosinophilic asthma (n = 12), NEA (n = 25) and healthy non-smoking controls (n = 30). We applied flow cytometry to measure T, CD28null, NK and NKT-like cells and their expression of granzyme B, perforin, and killer inhibitory/activating receptors CD94(Kp43), CD158b and CD107A. Intracellular pro-inflammatory cytokine production (IFN-¿ and TNF-a) was assessed in 18 controls and 10 patients with asthma/group. Results: In NEA, there was increased expression of granzyme B by CD8+ T cells vs. controls. There was increased expression of granzyme B and CD158 and decreased CD94 on NK cells, vs. healthy controls and those with eosinophilic asthma. IFN-¿ production by NK cells and TNF-a production by NKT-like cells in NEA were significantly increased vs. controls. In both eosinophilic and NEA phenotypes, there were significant increases in CD4+28null T cells (72% and 81% increases, respectively, vs. controls) and their expression of pro-inflammatory cytokines. Significant correlations were noted between blood CD4+28null T cells and neutrophil numbers in induced sputum, and between corticosteroid dose and blood NKT-like cells, and their production of granzyme B and TNF-a and NK IFN-¿. Conclusion and clinical relevance: In poorly controlled asthma, altered expression of cytotoxic/pro-inflammatory mediators can be seen on a variety of lymphocyte subsets in the peripheral blood; these changes are most apparent in NEA. Whether this pattern of expression is a marker of treatment responsiveness and future risk of exacerbations remains to be determined.

Yes, and this belief that non-Jews are inherently anti-Semitic represents a strong anti-Gentile bias intrinsic to Zionism.

Statistics show that the mortality rate decrease which was seen a few years ago has stopped. In some countries we see (figures from 2015 and 2016) a significant increase in primary detection in Stage IV (advanced and metastatic prostate cancer). This must be reflected in the mortality rate in the years to come.

Annie Robbins – Avigail was willing to offer a recipe for solution. She called for ending the Jewish state. Her recipe isn’t really a solution, because she doesn’t admit or she doesn’t realize that ending the existence of Israel is not the end of conflict (the Jews who arrived after 1917 would have to leave). Sadly, she has decided to end the conversation. However, it was admirable that one of the writers at Mondoweiss had the honesty to say in clear words that the agenda is the demise of Israel. It is rather silly. It’s so obvious that you oppose the very existence of Israel, and that you have no vision of peace with Israel.

Prostate cancer is a very serious disease among older men. According to the American College of Physicians, one out of 16 men will receive a diagnosis of prostate cancer in their lifetimes, although only 2.9% will die of it, most of them older than 75. Nonetheless, PSA screening does not help: it carries a significant risk of harm. In this week’s NEJM article, Pinsky et al. conclude:

Stimulation of naïve murine peritoneal macrophages (Fig. 1A) or bone marrow-derived macrophages (BMMs) (Fig. 1B) with murine Mrp8 (mMrp8) for 6 h caused an inflammatory response quantified by significant release of TNF-α and IL-6 compared with macrophages incubated with culture medium alone. Pre-stimulation of murine peritoneal macrophages or BMMs with mMrp8 attenuated the release of TNF-α and IL-6 to a subsequent mMrp8 re-stimulation (Fig. 1A,B). A minimum of 18 h pre-stimulation was required to achieve statistically significant attenuation in TNF-α (Fig. 1C) and IL-6 (Fig. 1D) release. The pre-stimulating effect of mMrp8 was also dose-dependent, with increasing doses of mMrp8 pre-stimulant leading to a greater attenuation in either TNF-α or IL-6 release (Fig. 1A,B). Cell viability was not altered by mMrp8 pre-stimulation as confirmed by Resazurin assay (Supplementary Fig. 1A,B), excluding this as a possible cause for the reduced TNF-α and IL-6 release in mMrp8 pre-stimulated murine macrophages.

It doesn’t all have to be about low-light, though. With 19 auto-detected scene modes built-in (that’s the AI at work, identifying people versus pets and food versus flowers, etc), high dynamic range (HDR) and other tricks Night mode for handheld long exposures, there’s quality abound.

Foster says his team has made a significant contribution to the understanding of the mechanisms of steroid-resistant inflammatory pathways that may be relevant to asthma, bringing them closer to the goal of developing alternative treatments. Other critical areas of laboratory research focus on allergies, viruses and infection as triggers for asthma.

A deleterious effect of ROS on mitochondria is also displayed in a model of age-related skeletal muscle dysfunction. Umanskaya et al demonstrated a decrease in the pathologic intracellular Ca leak with antioxidant treatment. This intracellular finding was associated with gross changes in anatomical function in the form of whole organism exercise capacity and the specific force performance of skeletal muscle47. These findings further strengthen the position that ROS are involved in multiple pathophysiologic processes and the potential for antioxidant treatments that provide a selective yet adequate effect.
