Johanna Henriksns, Christer Atuma, Mia Phillipson, Stellan Sandler, Lars Engstrand, Lena Holm
World Journal of Gastroenterology , 2009,
Abstract: AIM: To investigate the mechanisms underlying the reduction in gastric blood flow induced by a luminal water extract of Helicobacter pylori (HPE).METHODS: The stomachs of isoflurane-anesthetized mice were exteriorized, and the mucosal surface exposed. Blood flow was measured with the laser-Doppler technique, and systemic arterial blood pressure monitored. C57BL/6 mice were exposed to water extract produced from H pylori strain 88-23. To investigate the role of a nerve- or iNOS-mediated pathway, we used intraluminal lidocaine and iNOS-/- mice. Blood flow response to the endogenous nitric oxide synthase inhibitor asymmetric dimethyl arginine (ADMA) was also assessed.RESULTS: In wild-type mice, HPE decreased mucosal blood flow by approximately 30%. This reduction was abolished in iNOS-deficient mice, and by pre-treatment with lidocaine. Luminally applied ADMA resulted in reduction in blood flow similar to that observed in wild-type mice exposed to HPE.CONCLUSION: A H pylori water extract reduces gastric mucosal blood flow acutely through iNOS- and nerve-mediated pathways.

Linear Dimension Reduction for Multiple Heteroscedastic Multivariate Normal Populations  [PDF]
Songthip T. Ounpraseuth, Phil D. Young, Johanna S. van Zyl, Tyler W. Nelson, Dean M. Young
Open Journal of Statistics (OJS) , 2015, DOI: 10.4236/ojs.2015.54033
Abstract: For the case where all multivariate normal parameters are known, we derive a new linear dimension reduction (LDR) method to determine a low-dimensional subspace that preserves or nearly preserves the original feature-space separation of the individual populations and the Bayes probability of misclassification. We also give necessary and sufficient conditions which provide the smallest reduced dimension that essentially retains the Bayes probability of misclassification from the original full-dimensional space in the reduced space. Moreover, our new LDR procedure requires no computationally expensive optimization procedure. Finally, for the case where parameters are unknown, we devise a LDR method based on our new theorem and compare our LDR method with three competing LDR methods using Monte Carlo simulations and a parametric bootstrap based on real data.
Perspectives for Wearable Electronics in Healthcare and Childcare  [PDF]
Johanna Virkki, Pasi Raumonen
E-Health Telecommunication Systems and Networks (ETSN) , 2013, DOI: 10.4236/etsn.2013.23008
Abstract: This paper starts with a literature survey that introduces possibilities of wearable electronics (WE) in different healthcare and childcare applications. Next, 24 personal interviews and an Internet forum survey were conducted in Finland about the use of WE in applications mentioned above. According to the results, most of the people feel positive about clothes used for wireless identification purposes in healthcare and childcare, but when more information about the person is added that can be wirelessly read, the feelings become more negative. Several important points to consider before implementation of WE for healthcare and childcare environments were brought up.
Process Adaption and Modifications of a Nutrient Removing Wastewater Treatment Plant in Sri Lanka Operated at Low Loading Conditions  [PDF]
Johanna Berg, Stig Morling
Materials Sciences and Applications (MSA) , 2013, DOI: 10.4236/msa.2013.45038
Abstract:

The Sri Lankan national water authority, that is The National Water Supply and Drainage Board (NWS&DB) has taken a new wastewater treatment plant into operation at Ja Ela, North of Colombo. The plant has been in operation since September 2011. In April 2012, it was concluded how a test of the aeration efficiency and a performance test should be carried out. The tests have been based on the actual loading of the plant and the analysis results from the daily process control. The evaluation of the aeration efficiency is not reported in this paper. The paper presents the overall performance of the water treatment part of the plant during start-up conditions, from fall 2011 through the first five months of 2012. The results from the operation are found in Table 1. An important circumstance at the plant is the current very low loading in comparison with the design load. This fact has resulted in an introduction of an intermittent mode of the aeration (nitrification) reactor. Based on operation figures, during more than a month (May 2012), it has been possible to give a realistic assessment of the overall performance. The most striking results are summarized as follows: 1) The intermittent operation has enabled an energy efficient operation of the plant. By the introduction of the intermittent aeration, the energy consumption has been reduced by around 75%, compared with the continuous operation mode; 2) The plant performance during the intermittent operation has been improved with respect to virtually all important pollu

Personal Perspectives: Individual Privacy in the IOT  [PDF]
Johanna Virkki, Liquan Chen
Advances in Internet of Things (AIT) , 2013, DOI: 10.4236/ait.2013.32003
Abstract:

The Internet of Things (IOT) is the extension of the Internet to the next level, i.e., bringing the Internet to the real physical world of things. In this research, 22 people working with different aspects of IOT development were interviewed in Finland and in China, in order to investigate their thoughts and personal opinions on the IOT and the individual privacy in the IOT. This paper presents the background of the IOT, interviews and collected answers, as well as highlights of collected free comments.

Privacy of Wearable Electronics in the Healthcare and Childcare Sectors: A Survey of Personal Perspectives from Finland and the United Kingdom  [PDF]
Johanna Virkki, Rebecca Aggarwal
Journal of Information Security (JIS) , 2014, DOI: 10.4236/jis.2014.52005
Abstract:

The innovative development of Wearable Electronics (WE) is creating exciting opportunities for application across many industries. Two sectors with high potential are healthcare and childcare. However, it is in these two sectors where the challenges of privacy are presumed to be of the highest. In order to ascertain the personal views of people about potential privacy problems in WE application in these two sectors, interviews with questionnaires were conducted in two different countries: Finland and the United Kingdom (UK). The results indicated that the majority of people in both countries are positive about the use of WE in healthcare and childcare environments. However, when more information is added to be read wirelessly, the attitudes become more negative. In general, the application of WE is more favorable in the UK and the reason as to the difference will make for interesting further research. Several interesting viewpoints and concerns were presented in the interviews. It can be concluded that the implementation of WE in these two sectors will require the collaboration of work on several areas and the development of versatile user studies.

Health (Health) , 2014, DOI: 10.4236/health.2014.614209
Abstract: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides are characterized by destruction of small vessels, granulomatous inflammation of the respiratory tract and necrotizing glomerulonephritis. This review describes the clinical diagnosis and therapy as well as the patho-physiology of ANCA-associated vasculitides with a specific focus on the interplay of ANCAs with activated neutrophils and the deleterious pathophysiological consequences of neutrophil-endothelium interaction.
Comparison of the Specialist Medical Training in Internal Medicine between Germany, Austria and Switzerland: An Overview  [PDF]
Johanna Braun, Ursula Gresser
Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.811118
Abstract: Specialists for internal medicine are very important group of the medical profession. Although they make up the largest group of specialized physicians, there is a shortage of physicians, and in particular of internists in Germany, Austria and under some aspects in Switzerland. Germany, Austria and Switzerland show also an intensive transfer of physicians. It is therefore of interest to investigate if the tern “internist” in the three countries under consideration is based on the same or equivalent education, in particular regarding the quality standards. Exchange date between the three countries, the organisation of the medical profession, the access requirements to the specialist medical training, the structure of the specialist’s training as well as the requirements for keeping the specialist’s name have been compared. The main differences are the access requirements and the linkage of the qualification to the independent exercise of the medical profession. Also regarding the performance catalogues, the Swiss education follows a different approach as in Germany and Austria.
