There are a variety of approaches to seismic sensing, which range from collecting sparse measurements with high-fidelity seismic stations to non-quantitative, post-earthquake surveys. The sparse nature of the high-fidelity stations and the inaccuracy of the surveys create the need for a high-density, semi-quantitative approach to seismic sensing. To fill(More)
A novel Near Field Communication (NFC) based solution to support medication management of vision impaired older users is presented in this paper. The service concept allows older users with vision impairments to manage their daily medications autonomously by providing them means to identify medicines and retrieve personal medication information. In order to(More)
Elevated transferrin receptor (TfR) concentration may be either because of iron deficiency or an increased rate of erythropoiesis. We have studied the relationship between elevated TfR and advanced RBC and reticulocyte indices in an unselected population of hospitalized patients. The iron status in 95 consecutive hospitalized patients was assessed using(More)
The aim of this study was to evaluate the relationship between the erythropoietin (EPO) concentration and both the advanced cellular indices reflecting the haemoglobin contents of red blood cells and reticulocytes and the serum markers of iron status. The study population comprised pregnant women at term (n = 210). The serum EPO, transferrin receptor (TfR),(More)
OBJECTIVES Detection of iron deficiency during pregnancy with hemoglobin (Hb) and serum measurements is insignificant as the measurements may be affected by e.g. hemodilution or accelerated erythropoiesis. This study tests whether cell indices will give a more reliable measure of iron deficiency in pregnant women at term. METHODS The population was 202(More)
OBJECTIVE To investigate the associations between maternal iron status, pregnancy outcome and newborn iron status using sensitive and specific red blood cell indices reflecting iron-deficient erythropoiesis. DESIGN AND SETTING Cross-sectional study in Kuopio University Hospital, Finland. POPULATION One hundred and ninety-two pregnant women and their(More)
OBJECTIVE Hepcidin, a small 25 amino-acid antimicrobial peptide, has a significant role in the regulation of iron homeostasis. Pro-hepcidin, an 84 amino-acid peptide, is a precursor of the active hepcidin. The main aim of this study was to examine the association of maternal serum pro-hepcidin with cord blood pro-hepcidin levels in term pregnancies, and(More)
BACKGROUND The aims of this study were to assess the relationship between red blood cell and reticulocyte indices and biochemical iron status measurements, and to define reference values of these markers in the cord blood of newborns. METHODS In cord blood samples from 199 full-term newborns, cellular indices were assessed using an ADVIA 120 hematology(More)
The "iShake" system uses smartphones as seismic sensors to measure and deliver ground motion intensity parameters produced by earthquakes more rapidly and accurately than currently possible. Shaking table tests followed by field trial with approximately 30 iShake users were implemented to evaluate the reliability of the phones as seismic monitoring(More)
