Ever since the recognition of calcium as a major intracellular messenger of signal transduction, its subcellular localization and intracellular movements have been intensively sought through electron and light optical methods. Electron probe microanalysis (EPMA), X-ray mapping, electron energy-loss spectroscopy (EELS) and energy-filtered imaging still provide the highest spatial resolution for measuring total calcium, whereas with light optical methods (fluorescent, luminescent and absorbance dyes) free [Ca2+]i can be measured with high sensitivity and time resolution. This presentation will summarize the relationship, whether collision or convergence, between the results of electron and light optical methods, with particular reference to mitochondrial Ca, and consider the potential for further improvements in detection sensitivity and spatial resolution.Sarcoplasmic and endoplasmic reticulum: Early attempts to quantitate Ca in cellular organelles with EPMA were directed at the sarcoplasmic reticulum (SR) of skeletal muscle, where EPMA could also address questions not amenable to studies of isolated SR.

Clostridium difficile infection (CDI) has become the main cause of diarrhea-related diseases in domestic (China) inpatients. High-sensitivity and high-specificity detection methods for CDI must be applied clinically for CDI supervisory control. In this paper, we introduce a detection method for C. difficile and Norovirus based on real-time PCR. We developed and optimized a primer–probe for Norovirus targets tcdA and tcdB with remarkably increased detection sensitivity. We then used this method in an integrated cassette, and found increased detection efficiency for Norovirus standards in the cassette compared to C. difficile samples. These results provide a basis for further exploration of automatic testing system design.

The Relationship

Abstract. Recently, Garfinkel and Critchley (2013) proposed to distinguish between three facets of interoception: interoceptive sensibility, interoceptive accuracy, and interoceptive awareness. This pilot study investigated how these facets interrelate to each other and whether interoceptive awareness is related to the metacognitive awareness of memory performance. A sample of 24 healthy students completed a heartbeat perception task (HPT) and a memory task. Judgments of confidence were requested for each task. Participants filled in questionnaires assessing interoceptive sensibility, depression, anxiety, and socio-demographic characteristics. The three facets of interoception were found to be uncorrelated and interoceptive awareness was not related to metacognitive awareness of memory performance. Whereas memory performance was significantly related to metamemory awareness, interoceptive accuracy (HPT) and interoceptive awareness were not correlated. Results suggest that future research on interoception should assess all facets of interoception in order to capture the multifaceted quality of the construct.

The scientific problem of economics “Managing the quality of human life” is formulated on the basis of artificial intelligence, algebra of logic and logical-probabilistic calculus. Managing the quality of human life is represented by managing the processes of his treatment, training and decision making. Events in these processes and the corresponding logical variables relate to the behavior of a person, other persons and infrastructure. The processes of the quality of human life are modeled, analyzed and managed with the participation of the person himself. Scenarios and structural, logical and probabilistic models of managing the quality of human life are given. Special software for quality management is described. The relationship of human quality of life and the digital economy is examined. We consider the role of public opinion in the management of the “bottom” based on the synthesis of many studies on the management of the economics and the state. The bottom management is also feedback from the top management.
