Objective. The main purpose of the research was to develop a coefficient cardiorespiratory system status, which will take into account both frequency and power characteristics external respiration hemodynamics activity. Compare an informativeness this with universally accepted Hildebrandt one.
 Materials Methods. 154 apparently healthy young people sexes were examined. On bicycle ergometer...

Time irreversibility, a fundamental property of nonequilibrium systems, should be of importance in assessing the status of physiological processes that operate over a wide range of scales. However, measurement of this property in living systems has been limited. We provide a computational method derived from basic physics assumptions to quantify time asymmetry over multiple scales and apply it ...

To assessment growth physiological charachteristics of two hybrids of sweet corn affected different irrigation pattern and zinc fertilization, a research was conducted as split plot factorial experiment based on randomized complete blocks design with three replications. Main factor included different levels of irrigation pattern included conventional furrow irrigation, fixed every other furrow ...

The relationship between the Electrophoretic Mobility of Cell Nuclei (EMN) index before and after super-maximal and maximal exercises and changes in physiological parameters associated with acid-base balance of the blood (pH, BE) and lactic acid concentration (LA) were examined in junior (N = 33, X = 15.6 y.o. SD = 1.16 y.), and senior (N = 10, X = 22.0 y.o. SD = 2.70 y.) female rowers. The fol...

UNLABELLED The physiological course of pregnancy is closely related to adequate development of the placenta. Shallow invasion of trophoblast as well as decreased development of the placental vascular network are both common features of preeclampsia. To better understand the proangiogenic features of mast cells, in this study we aim to identify the potential relationship between the distribution...

It has been shown that negative affect causes attentional narrowing. According to Easterbrook's (1959) influential hypothesis this effect is driven by the withdrawal motivation inherent to negative emotions and might be related to increases in arousal. We investigated whether valence-unspecific increases in physiological arousal, as measured by pupil dilation, could account for attentional narr...

Bacterial pathogens in coastal aquatic ecosystems pose a potential public health hazard for bathing water use. The European Bathing Water Directive (2006/7/EC) currently relies on the culturability of fecal pollution bacterial indicators such as Escherichia coli, without considering dormant or quiescent (Viable But Not Culturable, VBNC) cells, whose possible resuscitation after bathers ingestio...

atraumatic restorative treatment (art) is a minimal intervention technique in the management of carious lesions, which results in negligible discomfort to the patient. the aim of this study was to assess and compare the discomfort levels during atraumatic restorative treatment and minimal cavity preparation (mcp: a method using rotary instruments) treatment procedures in a sample of school chil...
