Stepwise reduction of the culture redox potential allows the analysis of microaerobic metabolism and photosynthetic membrane synthesis in Rh...
Biotechnol Bioeng 110(2):573-85 (2013) PMID 23042159
We introduce a robust and reliable microaerobic process control strategy, which applies the culture redox potential (CRP) for assessing different degrees of oxygen limitation in bioreactor cultivations. To describe the microaerobic growth behavior of R. rubrum cultures for each of these defined CRP... -

Respiratory health in women: from menarche to menopause.
Expert Rev Respir Med 6(2):187-200; quiz 201-2 (2012) PMID 22455491
Gender differences in respiratory health have, in recent years, been the focus of considerable scientific effort. This paper reviews recent literature on respiratory health in women in relation to age at menarche, menstrual cycle, irregular menstruation, polycystic ovarian syndrome,... -
Effects of assisted and variable mechanical ventilation on cardiorespiratory interactions in anesthetized pigs.
Physiol Meas 33(3):503-19 (2012) PMID 22373541
We compared the effects of pressure controlled (PCV) versus pressure assisted (PSV) ventilation, and of random variable versus constant V(T), on RSA and CVC in eight anesthetized pigs. At comparable depth of anesthesia, global hemodynamics, and ventilation, RSA amplitude increased from 20 ms in PCV... -
Computational models for the study of heart-lung interactions in mammals.
Wiley Interdiscip Rev Syst Biol Med 4(2):163-70 (2012) PMID 22140008
The operation and regulation of the lungs and the heart are closely related. This is evident when examining the anatomy within the thorax cavity, in the brainstem and in the aortic and carotid arteries where chemoreceptors and baroreceptors, which provide feedback affecting the regul... -
The effect of body warming on respiratory system stress recovery in the rat.
Acta Bioeng Biomech 14(3):59-66 (2012) PMID 23140392
We performed experiments in which constant deflation flow arrest was applied in rats to study the successive pressure-time course, which defines the visco-elastic stress recovery. To investigate the possible effects of temperature changes, measurements were performed at two body temperatures, 36.6 ... -
Linking Inflammation, Cardiorespiratory Variability, and Neural Control in Acute Inflammation via Computational Modeling.
Front Physiol (2012) PMID 22783197 PMCID PMC3387781
We have developed signal-processing algorithms that quantify non-linear deterministic characteristics of variability in biologic signals. Now, coalescing under the aegis of the NIH Computational Biology Program and the Society for Complexity in Acute Illness, two research teams performed iterative e... -
Circadian rhythms: from basic mechanisms to the intensive care unit.
Crit Care Med 40(1):246-53 (2012) PMID 21926587
: Critically ill patients may be highly vulnerable to disruption of circadian rhythms as a result of the severity of their underlying diseases as well as the intensive care unit environment where noise and frequent therapeutic/diagnostic interventions take place. Further basic and clinical research a... -
Integration of Biomonitoring and Instrumental Techniques to Assess the air Quality in An Industrial Area Located in the Coastal of Central A...
J Toxicol Environ Health A 75(22-23):1392-403 (2012) PMID 23095157
Throughout the world, epidemiological studies were established to examine the relationship between air pollution and mortality rates and adverse respiratory health effects. However, despite the years of discussion the correlation between adverse health effects and atmospheric polluti... -
Opposing effects of bone morphogenetic protein-2 and endothelin-1 on lung fibroblast chloride currents.
Am J Respir Cell Mol Biol 45(6):1154-60 (2011) PMID 21659661
We hypothesized that these channels are differentially regulated by BMP's and endothelin. We measured chloride ion currents by whole-cell path-clamping in cultured primary human pulmonary fibroblasts. The application of BMP-2 prevented activation of these currents by hypotonic challenge in time- and...
