Abstract. Satellite-based observations of atmospheric carbon dioxide (CO2) provide measurements in remote regions, such as the biologically sensitive but undersampled northern high latitudes, and are progressing toward true global data coverage. Recent improvements satellite retrievals total column-averaged dry air mole fractions CO2 (XCO2) from NASA Orbiting Carbon Observatory 2 (OCO-2) have a...

1. A protein was demonstrated in mammalian islets of Langerhans that after purification appeared as a single component possessing both cyclic-AMP (adenosine 3':5'-cyclic monophosphate)-binding and cyclic-AMP-dependent protein phosphokinase activities. 2. The protein had an intrinsic association constant for cyclic AMP of 1.15x10(-8)m, which was similar to the K(m) for cyclic AMP (1.11x10(-8)m) ...

Coffee production has decreased due to environmental and management factors. The current plantations are old unproductive, also the rust problem, caused by fungus Hemileia vastatrix Berk & Br. Furthermore, shade in systems with consequent increase soil erosion, addition agrochemicals. Currently, planting of new varieties resistance is increasing. it been shown that various biofertilized perenni...

Mitochondrial proton leak in rat muscle is responsible for approx. 15% of the standard metabolic rate, so its modulation could be important in regulating metabolic efficiency. We report in the present paper that physiological concentrations of AMP (K(0.5)=80 microM) increase the resting respiration rate and double the proton conductance of rat skeletal-muscle mitochondria. This effect is specif...

Stimulation of catecholamine release was studied in the isolated adrenal of the cat during retrograde perfusion. Theophylline, adenosine 3':5'-cyclic monophosphate (cyclic AMP), and dibutyryl-cyclic AMP stimulated catecholamine release in adrenal chromaffin tissue; adenosine, 2'-AMP, 3'-AMP, and 5'-AMP were ineffective. Addition of theophylline for 5-15 min had no effect on catecholamine releas...

Use of biomass in domestic cookstoves leads to the release oxides nitrogen (NOx), nitric oxide (NO), dioxide (NO2), carbon monoxide (CO) and hydrocarbons CxHx that can be detrimental health public environment. Attainment complete combustion is best strategy for mitigating these emissions. This study sought experimentally determine effects secondary air injection on emission profiles NOx (NO & N...

The AMP-dependent stimulation of the cyanide-insensitive respiration of Paramecium mitochondria was investigated. The nucleotides exhibiting a stimulatory effect on the cyanide-insensitive oxidation of pyruvate (+ malate) in a medium supplemented with EDTA or carboxyatractyloside were, in decreasing order of efficiency, AMP, GMP, IMP, UMP and TMP. On the other hand, ADP, ATP and cyclic AMP were...
