We conducted a literature review to identify scenarios in which occupational benzene exposure has occurred, which we grouped into 12 categories of benzene exposure sources. For each source category, we then developed decision rules for assessing probability (ordinal scale based on the likelihood of exposure > 0.02 ppm)... |
RESULTS |
Of the 8827 jobs reported by participants, 8% required expert review for one or more source categories. Overall, 287 (3.3%) jobs were assigned ≥75% probability of exposure from any benzene source category. The source categories most commonly assigned ≥75% probability of exposure were gasoline and degreasing. The median... |
CONCLUSIONS |
The applied framework captures some subject-specific variability in work tasks, provides transparency to the exposure decision process, and facilitates future sensitivity analyses. The developed decision rules can be used as a starting point by other researchers to assess occupational benzene exposure in future populat... |

INTRODUCTION |
The internationalization of societies and the processes of globalization raise new challenges towards health provision systems, including professional, ethical, social, cultural and communicational references of nursing and nursing education. |
AIMS |
In this study the authors wanted to answer the following question: To what extent are health care professionals aware of and able to respond to the new challenges? |
METHODS |
As an investigation method, the authors used a questionnaire and made a comparative analysis of answers related to the knowledge, skills and attitude of BSc nurses and other health professionals who possess a secondary qualification. The questionnaire was compiled based on the internationally accepted and validated Tra... |
RESULTS |
There were better results in the components of skills and attitude of BSc nurses but there was a very high number of professionals in both groups who either failed to have or could not meet the requirements and phenomena related to intercultural skills. |
CONCLUSIONS |
The survey performed among nurses proved that there is a real demand for intercultural skills and knowledge related to expectations of the society. In order to improve the quality of health care, the development of these skills is necessary.Kamikihi-to (KKT) Rescues Axonal and Synaptic Degeneration Associated with Memo... |

BACKGROUND |
Prostacyclin is an important mediator of renal hemodynamics. Furthermore, recent studies argue for a role of this arachidonic acid metabolite in the regulation of salt and water handling in the distal nephron. To gain insight into the network of prostacyclin signal transduction, we analyzed the intrarenal distribution ... |
METHODS |
Specific polyclonal antibodies against a synthetic peptide of the human IP receptor were generated. By means of immunohistology the localization of IP receptor protein was studied. The mRNA expression for IP receptor was analyzed by in situ hybridization using specific cRNA probes. |
RESULTS |
In human kidney sections both IP receptor-immunoreactive protein and mRNA were expressed in smooth muscle cells and endothelial cells. Expression of the IP receptor was observed in glomerular cells, namely mesangial cells, endothelial cells, and podocytes. Both mRNA and protein expression for IP receptor was observable... |
CONCLUSIONS |
The vascular expression of the IP receptor is consistent with the known vasodilatory effect of prostacyclin in vascular beds. Glomerular expression argues for a role of this autacoid in the regulation of glomerular hemodynamics. The tubular distribution might point towards the involvement of prostacyclin in renal salt ... |
