However, there are limited smartphone apps for the long-term health management of chronic diseases. More smartphone apps need to be developed to help people manage chronic diseases.
There are about one billion patients with iron deficiency anaemia all over the world. Recently, researchers have reported successively that stress can cause decrease of serum iron, in consistent with our studies showing that heat exposure and acceleration stress led to significant decrease of serum iron in rats. However, so far whether pure psychological stress can cause decrease of serum iron and consequently affect erythropoiesis has not been reported. To study the characteristic effects of psychological stress on serum iron and erythropoiesis, and to establish an useful experimental basis for further study involving how sufficient intake of dietary iron causes decrease of serum iron and the consequent effects on physiological function of the human body. Psychological stress was administered to 20 rats with Communication Box system. On the 7th and 14th day after administration, 10 rats were executed, respectively, and the rat blood and femoral bone marrow were collected for analysis of serum iron (SI), serum ferritin (SF), serum transferrin receptor (sTfR), haemoglobin (Hb), red blood cell count (RBC), RBC distribution width (RDW), mean corpuscular volume (MCV), serum erythropoietin (EPO) and bone marrow iron. Experimental data were statistically analysed with SPSS 11.0. For rats analysed on the 7th and 14th day in psychological stress group, (1) femoral bone marrow iron was significantly decreased; (2) serum iron was decreased by 28.6% (P < 0.01) and 27.5% (P < 0.01); (3) Hb was decreased by 10.0% (P < 0.01) and 12.8% (P < 0.01), RBC count was decreased by 5.1% (P < 0.05) and 9.8% (P < 0.01), MCV was decreased by 1.7% (P < 0.05) and 7.3% (P < 0.01), RDW was increased by 10.7 and 22.5%; (4) serum ferritin, transferrin receptor and EPO showed no significant changes in comparison with controls after 7-day administration, but serum ferritin and EPO were decreased by 23.8 and 12.3% while transferrin receptor increased by 31.5% after 14-day administration. For rats receiving different period of pure psychological stress: (1) serum iron and bone marrow iron showed significant decrease compared with the controls; (2) erythropoiesis was significantly inhibited; however, (3) how psychological stress affects serum iron and erythropoiesis need to be further investigated.
Identifying individual's political ideology from their speeches and written texts is important for analyzing political opinions and user behavior on social media. Traditional opinion mining methods rely on bag-of-words representations to classify texts into different ideology categories. Such methods are too coarse for understanding political ideologies. The key to identify different ideologies is to recognize different opinions expressed toward a specific topic. To model this insight, we classify ideologies based on the distribution of opinions expressed towards real-world entities or topics. Specifically, we propose a novel approach to political ideology detection that makes predictions based on an opinion-aware knowledge graph. We show how to construct such graph by integrating the opinions and targeted entities extracted from text into an existing structured knowledge base, and show how to perform ideology inference by information propagation on the graph. Experimental results demonstrate that our method achieves high accuracy in detecting ideologies compared to baselines including LR, SVM and RNN.
Oncology nurses should develop a holistic home-based care plan by exploring and integrating the discordance of needs assessment of both patients and health providers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
