[Microcalorimetry -- a new method for bacterial characterisation].

The microcalorimetry is a method used for recording of the heat produced by a thermodinamic system in a scale of micronanojouls. One of the domains in which this method is used is the one called bacterial microcalorimetry, which studies the heat generated by the bacterial populations. The process of bacterial growth can be monitored in real time by the recording a graph of the generated power over time.

Comparative analysis of Staphylococcus aureus and Escherichia coli microcalorimetric growth.

Background: Microcalorimetric bacterial growth studies have illustrated that thermograms differ significantly with both culture media and strain. The present contribution examines the possibility of discriminating between certain bacterial strains by microcalorimetry and the qualitative and quantitative contribution of the sample volume to the observed thermograms. Growth patterns of samples of Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 25922) were analyzed.

Psychoemotional features of a doubtful disorder: functional dyspepsia.

Objective: To delineate the psychological profile of individuals prone to FD-like symptoms (FDLS).

Method: A triple questionnaire of 614 items (including psychological and medical ones) was given to 10192 respondents, the results were analyzed by means of Cronbach alpha, and Chi square test, together with an ad-hoc designed method that implied ranking and outliers detecting.

Results And Conclusions: FDLS appears to be an accompanying feature of many (if not most) human emotions and are more frequent in anxious, timid, pessimistic, discontent, irascible, tense, success-doubting, unexpected-dreading individuals, bothered by persistent thoughts and tormented by the professional requirements and the lack of time.
