Specific ATP content of volatile solids was measured to characterize the sludge activity in a sequential an-aerobic/aerobic wastewater treatment system, with an upflow anaerobic sludge blanket (UASB) reactor and a three-phase aerobic fluidized bed (AFB) reactor. The wastewater COD level was 2000-3000 mg/L in simulation of real textile waste-water. The ATP content and the specific ATP contents o...

the objective of the present study was to investigate the role of nanocarrier of magnetic isotope of 25-mg2+ (pmc16) in liver toxicity, atp content and oxidative stress due to malathion (mal) exposure. pmc16 nanoparticle were administered in different doses (0.05, 0.1 and 0.2 ld50) intravenously (iv) 40 minutes after a single mal (0.25 ld50= 207 mg/kg) intraperitoneal (ip) injection as a comple...

Membrane technology can minimize spread of viruses in the environment during pandemics, however, its efficiency is highly limited by biofouling. In current study, a composite membrane composed commercial material, poly(vinylidene fluoride) (PVDF), and thermo-responsive attapulgite (t-ATP) was developed. The t-ATP synthesized surface modification (ATP) nanofiber with poly(N-isopropylacrylamide) ...

Low-level-laser therapy (LLLT) is an effective complementary treatment, especially for anti-inflammation and wound healing in which dermis or mucus mast cells (MCs) are involved. In periphery, MCs crosstalk with neurons via purinergic signals and participate in various physiological and pathophysiological processes. Whether extracellular ATP, an important purine in purinergic signaling, of MCs ...

Abstract The production of environmentally friendly SAP using biodegradable natural resources such as chitosan was synthesized for water saving and controlled-released fertilizer. Chitosan-g-poly(acrylamide)/attapulgite superabsorbent composites (CTS) were created by crosslinking N , '-methylene-bis-acrylamide (MBA) with (Ch), acrylamide, attapulgite (ATP) initiating the reaction potassium pers...

The effect of subarachnoid hemorrhage on metabolic rates in rabbit cerebral arteries was investigated by measuring adenosine triphosphate (ATP) content and L-lactate release. The mean +/- SEM ATP content was 0.38 +/- 0.02 mumol/g wet wt in control rabbit basilar arteries (n = 6). The ATP content decreased significantly to 0.17 +/- 0.02 mumol/g wet wt 2 days after experimental subarachnoid hemor...

ATP synthase β subunit (ATPSβ) had been previously shown to play an important role in controlling ATP synthesis in pancreatic β-cells. This study aimed to investigate the role of ATPSβ in regulation of hepatic ATP content and glucose metabolism in diabetic mice. ATPSβ expression and ATP content were both reduced in the livers of type 1 and type 2 diabetic mice. Hepatic overexpression of ATPSβ e...

BACKGROUND Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels that result from defects in insulin secretion, or action, or both. Inspired by previous report the release of ATP from RBCs, which may participate in vessel dilation by stimulating NO production in the endothelium through purinergic receptor signaling and so, the aim of this study is...

Confocal imaging was used to study the influence of cytosolic ATP on the properties of spontaneous Ca(2+) sparks in permeabilized ventricular myocytes. Cells were perfused with mock intracellular solutions containing fluo 3. Reducing [ATP] to <0.5 mmol/L decreased the frequency but increased the amplitude of spontaneous Ca(2+) sparks. In the presence of 20 micromol/L ATP, the amplitude increase...

Measurements of lactate production and ATP concentration in superfused rat retinas were compared with extracellular photoreceptor potentials (Fast PIII). The effect of glucose concentration, oxygen tension, metabolic inhibition, and light were studied. Optimal conditions were achieved with 5-20 mM glucose and oxygen. The isolated retina had a high rate of lactate production and maintained the A...
