Cherry Murray and Peggy Hamburg Elected Co-Chairs of IAP

Cherry Murray, a member of NAS and NAE, and Peggy Hamburg, NAM member and foreign secretary, have been elected as co-chairs of the InterAcademy Partnership (IAP) at the IAP General Assembly in Songdo, South Korea. IAP is the global network of over 140 science, engineering, and medical academies working together to provide independent, expert advice on scientific, technological, and health issues. Over the course of her career in physics, Murray has held prominent appointments in industry, academia, and the public sector, while Hamburg is a distinguished physician and public health administrator as well as president of the American Association for the Advancement of Science (AAAS). Murray and Hamburg were nominated by NAS President Marcia McNutt and NAM President Victor Dzau, respectively.

Authors: Proboszcz M, Mycroft K, Paplinska-Goryca M, Górska K, Nejman-Gryz P, Jankowski P, Zak N, Krenke R Abstract Blood eosinophilia has been proposed as a surrogate marker for airway eosinophilia and as a predictor of treatment response in chronic obstructive pulmonary disease (COPD). The aim of the study was to assess the relationship between blood and sputum eosinophils and to investigate the association between blood and sputum eosinophil count and clinical features of mild-to-moderate COPD. We performed a retrospective analysis of blood and sputum eosinophil count, as well as demographic and lung func...

Authors: Frykholm E, Lima VP, Selander HV, Nyberg A, Janaudis-Ferreira T Abstract While the mechanisms underlying exercise limitations and symptoms during leg activities have been investigated in detail, knowledge of potential differences between leg and arm activities are not well understood and results from individual studies are contradictory. Thus, the aim of the present study was to synthesize physiological and symptomatic responses during activities involving the arms relative to activities involving the legs in people with Chronic Obstructive Pulmonary Disease (COPD). Any study with a cross-sectional compari...

Conclusions: The constantly increasing prevalence of NAFLD in the general population can contribute to a growing role of NAFLD/NASH in HCC epidemiology. Moreover, some particular challenges specific for patients with liver steatosis may impede proper HCC diagnosis, treatment and follow-up. PMID: 31631714 [PubMed - as supplied by publisher]

Is this fate the only destiny for mitochondrial-leaked electrons? When Cynomolgus monkeys were injected intravenously with reactive oxygen species (ROS) in...

Conclusion: There is evidence that the bystander effects for both lethality and mutagenicity occurred in the unirradiated half of the cells, in which only half of the cells were irradiated with the carbon ions. These results suggest that the bystander cellular effects via gap-junction-mediated cell-cell communication are dependent on the type of radiation. PMID: 31633439 [PubMed - as supplied by publisher]

Conclusions: It has been concluded that effective atomic number and electron density of malathion is bigger than the other drugs and the variations in values of Zeff and Nel for all drugs depend on chemical compositions and photon energy where the K-absorption edge of elements may affect the energy dependence of Zeff and Nel. It should also be noted that the buildup of photons is less in malathion and carbachol and is more in tabun and parathion compared with other drugs. Photon interaction parameters evaluated in the present study may be beneficial in radiation dosimetry and therapy. PMID: 31633438 [PubMed - as supplied by publisher]

Conclusions: Apart from complex formulas that describe these phenomena, we discuss which simple formulas can best approximate them and when is the case to use them for curve fitting of micronuclei data. PMID: 31633434 [PubMed - as supplied by publisher]

Conclusions: SIF + XRT caused changes in patterns of endothelial cell death and survival, proinflammatory molecule release, and adhesion molecule expression at early time points post-XRT associated with early reduction of immune cell recruitment. These findings suggest that SIF could mediate its radioprotective effects in irradiated lungs by limiting excessive immune cell homing via vascular endothelium into damaged lung tissue and curtailing the overall inflammatory response to radiation.
