background: the mitochondria are an important source of adenosine triphosphate (atp) production in pre-implantation embryo. therefore, the objective of this study was to investigate the effect of vitrification and in vitro culture of mouse embryos on their mitochondrial distribution and atp content. methods: the embryos at 2-pn, 4-cell and blastocyst stages were collected from the oviduct of st...

mitochondrial generate cellular energy in the form of atp (adenosine triphosphate) by the process of oxidative phosphorylation (oxphos). most cells contain hundreds of mitochondrial.

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...

Diadenosine triphosphate is present in platelet-dense granules and released quantitatively on platelet aggregation. We have found that intact porcine aortic endothelial cells can efficiently hydrolyze extracellular diadenosine triphosphate. The products of diadenosine triphosphate hydrolysis are adenosine monophosphate and adenosine diphosphate. Adenosine diphosphate is a potent stimulus of pla...

While alarmone nucleotides guanosine-3',5'-bisdiphosphate (ppGpp) and guanosine-5'-triphosphate-3'-diphosphate (pppGpp) are archetypical bacterial second messengers, their adenosine analogues ppApp (adenosine-3',5'-bisdiphosphate) pppApp (adenosine-5'-triphosphate-3'-diphosphate) toxic effectors that abrogate growth. The alarmones both synthesized degraded by the members of RelA-SpoT Homologue ...

BACKGROUND & AIMS Adenosine 5'-triphosphate plays a role in peripheral sensory mechanisms and, in particular, mechanosensory transduction in the urinary system. P2X(3) receptors are selectively expressed on small-diameter sensory neurons in the dorsal root ganglia; sensory neurons from dorsal root ganglia L1 and S1 supply the colorectum. This study investigated whether purinergic signaling cont...

Immediate decreases of the concentrations of glycogen and phosphocreatine are found in continuously working muscles, and many seconds later decreases of the adenosine triphosphate are found also, The hydrolysis of the adenosine triphosphate, which involves the liberation of 2 moles of phosphate, may be detected in 40 seconds and reaches its maximumin 1 or 2 minutes in muscles working at the rat...
