    Determination of Different Biological Factors on the Base of Dried Blood Spot Technology

    Full text link
    It is well-known that distinct biological indices (analytes) have distinct variability. We try to use some mathematical algorithms to pick out a set of blood parameters which give an opportunity to retrieve the initial volume of the blood spotted, and use it to calculate exact concentrations of analyts interesting to a physician. For our analysis we used the database of biochemical blood parameters obtained in Russian Scientific Center of Roentgen-Radiology during 1995-2000, which includes more than 30000 of patients.Comment: 5 page

    In the work, the authors reveal the user preferences of the mobile application market. The study is based on the Strauss–Howe generational theory. The mobile application market appears to be dynamic and fast-growing in an environment of exponential growth in consumer demand and a highly competitive environment. In the article, the authors classify and identify categories and subcategories of mobile applications based on their functional and value purpose. This classification formed the basis for determining the dependence based on the analysis of contingency matrices between the preference of the application for its purpose and the age category of the user, which made it possible to identify the relationship between generations of users and their choice of certain types of applications. The text provides a justification for the choice of certain applications on a daily basis by generations X, Y, Z. The relevance of the study lies in the fact that the authors examine a market, the rapid growth of which is conditioned by the global socio-economic situation. The information obtained during the analysis of user preferences of the Russian mobile application market can be used by specialists in determining the target audience of a digital product and developing marketing strategies

    Measurement of intracellular concentration of fluorescently-labeled targets in living cells

    Get PDF
    Estimations of intracellular concentrations of fluorescently-labeled molecules within living cells are very important for guidance of biological experiments and interpretation of their results. Here we propose a simple and universal approach for such estimations. The approach is based upon common knowledge that the dye fluorescence is directly proportional to its quantum yield and the number of its molecules and that a coefficient of proportionality is determined by spectral properties of the dye and optical equipment used to record fluorescent signals. If two fluorescent dyes are present in the same volume, then a ratio of their concentrations is equal to a ratio of their fluorescence multiplied by some dye- and equipment-dependent coefficient. Thus, if the coefficient and concentration of one dye is known then the concentration of another dye can be determined. Here we have demonstrated how to calculate this coefficient (called a ratio factor) and how to use it for concentration measurements of fluorescently tagged molecules. As an example of how this approach can be used, we estimated a concentration of exogenously expressed neuronal Ca2+ sensor protein, hippocalcin, tagged by a fluorescent protein in a dendritic tree of rat hippocampal neurons loaded via a patch pipette with Alexa Fluor dye of known concentration. The new approach should allow performing a fast, inexpensive and reliable quantitative analysis of fluorescently-labeled targets in different parts of living cells
