The choice of variables is determined by preliminary information available to the observer and dependent on his knowledge, experience and intuition. The finite value of the amount of information available to the researcher leads to the inevitable aberration of the observed object. This causes the existence of an unremovable and intractable processing by any statistical methods, a comparative (respectively, relative) uncertainty of the model. The goal is to present a theoretical justification for the existence of this uncertainty and proposes a procedure for its calculation. The practical application of the informational method for choosing the preferred model for the Einstein formula and for calculating the speed of sound is demonstrated.展开更多

It is not only a linguistic phenomenon, but also a kind of social phenomenon, which is a reflection of the social culture in the language. Euphemism has already penetrated into all aspects of daily life, and reflected different national psychologies and cultural differences. As the development of the society and human civilization and the accelerated process of economic globalization, the role euphemism plays in human communication especially in cross-cultural communication has been increasingly prominent. Here a comparative study on English and Chinese euphemisms is made to help to be familiar with similarities and differences of the use of euphemism in English and Chinese languages so as to reduce errors resulting in cross- culture communication, and improve cross-cultural communicative competence.展开更多

She was found to have a 6074A 〉 T nucleotide transition in the TNXB gene causing an amino acid protein change at Asp2025Val classifed as likely pathogenic. We add this clinical report to the literature and classical human disease gene catalogs to identify this specific mutation as disease-causing. This gene variant was reported previously in a different 36-year-old patient who shared our patient’s symptoms of joint hypermobility, skeletal and joint pain, skin elasticity and musculoskeletal problems, thereby causing a more severe presentation than seen in the hypermobility type of Ehlers-Danlos syndrome （EDS）. At the time of writing, a few mutations in the TNXB gene have been recognized as pathogenic causing EDS due to tenascin-X defciency, but the variant identifed in our patient has not been recognized as pathogenic in online genetic databases. Our case study in combination with peer-reviewed literature suggests that the 6074A 〉 T nucleotide transition in the TNXB gene may be classifed as disease-causing for EDS due to tenascin-X defciency.展开更多

Desoxycholate-hydrogen sulfide-lactose (DHL) agar was used as the selective medium for Salmonella. Triple sugar iron (TSI) agar was used as the screening medium. Citric acid disks were placed on DHL agar. NaCl was added to both media. After 24 hours incubation, H2S production on DHL agar was stimulated by citric acid, whereas production was suppressed by adding NaCl. The color change in the bottom of the TSI medium was due to the low production of black FeS. The production of FeS was reduced by lower H2S production by Salmonella with an increasing concentration of NaCl from 0.5% to 3%. The inhibition of the black color meant that the color change due to glucose fermentation could be seen clearly in the bottom of the agar. The current method cannot detect glucose fermentation but the addition of more NaCl to the TSI medium allowed the visualization of glucose fermentation by Salmonella. Although H2S production of salmonella was promoted by citrate etc., being controlled by sodium chloride was proved in this study. Thus, we had developed a possibility of novel technique for the detection of Salmonella etc.展开更多

After the exclusion of external stimuli and local disorders, autoimmunity presents a potential intrinsic trigger even in idiopathic RS. We present a 47-year-old woman with severe and progressive RS in both hands and toes for 2 years. She did not have: a) clinical and laboratory evidence of systemic autoimmune diseases;b) prior drug exposure;c) local digits disease. She could not tolerate vasodilators. Since she had elevated C-reactive protein, she received MMF as immunosuppressive therapy. Within 2 weeks, her symptoms improved, and she remained disease-free for 2 years. In conclusion, blocking intrinsic autoimmune triggers with MMF is a safe, practical, and effective short- and long-term treatment for refractory primary RS.展开更多
