(, Carbon partitioning patterns of Opuntiaficus-indica, a widely cultivated crassulacean acid metabolism species, were analysed to estimate carbon fluxes. After labelling a cladode with 14CO2, activities of 14C in various organs were measured for 6 weeks; the observed 14C time-courses for 14C in the labelled cladode and for transfer into other organs were simulated with a compartment model. Wit...
This study was performed under greenhouse condition and completely randomized design for wheat and canola at near saturated soil moisture condition to field capacity (seven soil matric suction treatments including 20, 40, 60, 80, 110, 300 and 500 cm with three ) in two consecutive years. The results showed that as the soil moisture content decreases from saturation condition, root respiration r...
The respiratory activity of the sugar-tolerant (osmophilic) yeast, Saccharomyces rouxii, and the non-tolerant species, Sacchromyces cerevisiae, were compared after growth in a complex basal medium, the medium supplemented with polyethylene glycol (mol. wt 200) to give a water activity of 0-95, and the medium supplemented with glucose (24 and 36%, w/v). The properties compared were Qo2 (glucose)...
We examined carbon monoxide (CO) delivery by carbon monoxide-releasing molecule 2 (CORM-2) or hemoglobin (Hb) on cellular oxygen sensing and mitochondrial respiration in bovine aortic endothelial cells (BAECs). CORM-2 reduced hypoxia-inducible factor-1α (HIF-1α) and endothelin-1 (ET-1) expression in normoxic and hypoxic cells, but while Hb alone significantly reduced HIF-1α stabilization in hyp...
Crust restoration is increasingly being done but we lack quantitative information on soil improvements. The study aimed to elucidate the dynamics involving soil microbial biomass carbon and soil dissolved organic carbon in the re-vegetation chronosequences of a hillslope land with purple soil in Hengyang, Hunan Province. The soil can cause serious disasters with both soil erosion and seasonal d...
Some biochars produced by pyrolysis of biomass have the potential to sequester C and enhance nutrient supplies in agricultural soils. A 28-day lab incubation was used assess effects derived from pine chips (PC) or poultry litter (PL) applied at five application rates (0, 22.5, 45.0, 67.5, 90 Mg ha−1 equivalent). Biochars were two acidic Ultisols, a Cecil sandy loam Tifton loamy sand, found Geor...
Different forest types exert essential impacts on soil physical-chemical characteristics by dominant tree species producing diverse litters and root exudates, thereby further regulating size and activity of soil microbial communities. However, the study accuracy is usually restricted by differences in climate, soil type and forest age. Our objective is to precisely quantify soil microbial bioma...
NO and O(2) compete at cytochrome-c oxidase, thus potentially allowing NO to modulate mitochondrial respiration. We previously observed a decrease of myocardial phosphocreatine (PCr)/ATP during very high cardiac work states, corresponding to an increase in cytosolic free ADP. This study tested the hypothesis that NO inhibition of respiration contributes to this increase of ADP. Infusion of dobu...
Introduction Stroke is a common neurological disease that can have a negative effect on all parts of the body. The respiratory system is one of the parts of the body that may be damaged by stroke. The respiratory disorders caused by stroke can occur in all three sections of the breath; including metabolic respiration, behavioral respiration and emotional respiration. Disorder in each of these ...
Digitonin can be used to permeabilize selectively the plasma membrane of Trypanosoma cruzi epimastigotes without significantly affecting the functional integrity of mitochondria. Addition of digitonin at concentrations close to 64 microM caused decrease in the rate of basal respiration of epimastigotes similar to that caused by oligomycin. A further addition of carbonyl cyanide p-trifluoropheny...
