Background. There is sparse literature examining the ICB phase of aerobic- and anaerobic-trained athletes. Measurements of ICB phase values of athletes can help to evaluate the sport’s physiological demands and understand the physiological adaptations in response to physical training. Objectives. The purpose of this study was to examine the relationship between the isocapnic buffering (IC...

We have used digital fluorescence imaging techniques to explore the interplay between mitochondrial Ca2+ uptake and physiological Ca2+ signaling in rat cortical astrocytes. A rise in cytosolic Ca2+ ([Ca2+]cyt), resulting from mobilization of ER Ca2+ stores was followed by a rise in mitochondrial Ca2+ ([Ca2+]m, monitored using rhod-2). Whereas [Ca2+]cyt recovered within approximately 1 min, the ...

Estrogens attenuate cardiac hypertrophy and increase cardiac contractility via their cognate estrogen receptors (ERs) ERα and ERβ. Because female sex hormones enhance global glucose use and because myocardial function and mass are tightly linked to cardiac glucose metabolism, we tested the hypothesis that expression and activation of the ERα might be required and sufficient to maintain physiolo...

Plant roots utilize at least two distinct pathways with high and low affinities to accumulate K+. The system for high-affinity K+ uptake, which takes place against the electrochemical K+ gradient, requires direct energization. Energization of K+ uptake via Na+ coupling has been observed in algae and was recently proposed as a mechanism for K+ uptake in wheat (Triticum aestivum L.). To investiga...

Objectives: The overall objective is to determine the physiological limitation of nitrate uptake by Fuji apple trees on M9 rootstocks in the spring and early summer. This includes: • Measuring the influence of soil temperature on nitrate uptake by the roots • Determining the impact of tree N status on nitrate uptake, by considering that during the period of N remobilisation from storage, xylem ...

The cultivated plant climate association in agricultural yields is getting expanded consideration with regards to changing climatic conditions. Abiotic stressors can lead morpho-anatomical, physiological, and biochemical alterations harvests, resulting a significant loss of profit. A comprehension ecological elements their communication physiological cycles critical for improving practices. Dro...

A multivariate study was performed aiming at the optimization of a recombinant rhamnose inducible E. coli induction system with alkaline phosphatase as target product. The effects of typical factors with impact on post- as well as pre-induction feeding rates were investigated with respect to the space-time yield of the target product. The goal was increased understanding as well as quantitative...

Salinity is one of the most critical problems for agricultural development and threatens future food safety. Therefore, we aimed to investigate root application zinc oxide nanoparticles (ZnO-NPs; 0, 50, 100 mg/L), 24-epibrassinolide (EBL; 0.02, 0.04 µM), their combinations on growth performance maize (Zea mays L.) as a model plant grown under salt stress (i.e., 5 10 dS m−1) in hydroponic system...
