Systemic hypoxia elevates skeletal muscle interstitial adenosine levels in humans.
Vetëm përdoruesit e regjistruar mund të përkthejnë artikuj
Identifikohuni Regjistrohu
BACKGROUND
Adenosine is a potent vasodilator that has been shown to increase in cardiac tissue in response to hypoxia. However, peripheral vasodilatation also occurs during hypoxia, and the vasoactive substance(s) responsible for skeletal muscle vasodilation have not yet been completely identified.
Vesicular storage of adenosine triphosphate in the guinea-pig cochlear lateral wall and concentrations of ATP in the endolymph during sound exposure and hypoxia.

Identifikohuni Regjistrohu
Previous studies have revealed putative vesicular stores of adenosine triphosphate (ATP) in the marginal cells of the cochlear stria vascularis which may serve as a source of ATP for purinergic signalling. This study aimed to provide further evidence of ATP storage in the cochlea and to see whether
Adenosine A2A receptor involves in neuroinflammation-mediated cognitive decline through activating microglia under acute hypobaric hypoxia.

Hypobaric hypoxia (HH) at high altitudes leads to a wide range of cognitive impairments which can handicap human normal activities and performances. However, the underlying mechanism is still unclear. Adenosine A2A receptors (A2ARs) of the brain are pivotal to synaptic plasticity and cognition.
Tissue hypoxia in sleep apnea syndrome assessed by uric acid and adenosine.

Identifikohuni Regjistrohu
OBJECTIVE
Although the overnight increase in urinary uric acid/creatinine ratio (DeltaUA/Cr) is considered by some to be a marker of tissue hypoxia in patients with obstructive sleep apnea-hypopnea syndrome (OSAS), this index is not universally accepted. The purpose of this study was to confirm the
Hypoxia induces T-cell apoptosis by inhibiting chemokine C receptor 7 expression: the role of adenosine receptor A(2).

Hypoxia is a major characteristic of the tumor microenvironment, and its effects on immune cells are proposed to be important factors for the process of tumor immune escape. It has been reported that hypoxia affects the function of dendritic cells and the antitumor function of T cells. Here we
Hypoxia induces adenosine release from the rat carotid body.

Identifikohuni Regjistrohu
The effect of hypoxia on the release of adenosine was studied in vitro in the rat whole carotid body (CB) and compared with the effect of hypoxia (2%, 5% and 10% O(2)) on adenosine concentrations in superior cervical ganglia (SCG) and carotid arteries. Moderate hypoxia (10% O(2)) increased adenosine
Spinal adenosine A2(A) receptor inhibition enhances phrenic long term facilitation following acute intermittent hypoxia.

Phrenic long term facilitation (pLTF) is a form of respiratory plasticity induced by acute intermittent hypoxia. pLTF requires spinal serotonin receptor activation, new BDNF synthesis and TrkB receptor activation. Spinal adenosine 2A (A(2A)) receptor activation also elicits phrenic motor
Severe acute intermittent hypoxia elicits phrenic long-term facilitation by a novel adenosine-dependent mechanism.

Acute intermittent hypoxia [AIH; 3, 5-min episodes; 35-45 mmHg arterial PO(2) (Pa(O(2)))] elicits serotonin-dependent phrenic long-term facilitation (pLTF), a form of phrenic motor facilitation (pMF) initiated by G(q) protein-coupled metabotropic 5-HT(2) receptors. An alternate pathway to pMF is

Adenosine, a purine nucleoside, plays a variety of roles in cardiovascular and ventilatory control, and may be a marker of tissue hypoxia. There is, however, no direct evidence of an increase in plasma or in tissue levels of adenosine during moderate hypoxia in humans. We measured the plasma
Adenosine modulates hypoxia-induced atrial natriuretic peptide release in fetal sheep.

Identifikohuni Regjistrohu
The effects of adenosine on atrial natriuretic peptide (ANP) secretion were determined in chronically catheterized fetal sheep (> 0.8 term). Adenosine was infused into the the right jugular vein for 1 h at 8 +/- 0.4 (5 fetuses), 160 +/- 8 (6 fetuses), and 344 +/- 18 micrograms.min-1.kg estimated
Adenosine and cyclic AMP in cerebral cortex of rats in hypoxia, status epilepticus and hypercapnia.

Identifikohuni Regjistrohu
The influence of hypercapnia, hypoxia and status epilepticus on cerebral cortex concentrations of adenosine, adenine nucleotides and cyclic AMP was studied on lightly anaesthetized (70% N2O) and artificially ventilated rats. Neither hypercapnia (arterial PCO2 about 80 and about 300 mmHg) nor hypoxia

In humans, hypoxia leads to increased sympathetic neural outflow to skeletal muscle. However, blood flow increases in the forearm. The mechanism of hypoxia-induced vasodilation is unknown. To test whether hypoxia-induced vasodilation is cholinergically mediated or is due to local release of

Ischemia/reperfusion and hypoxia/reoxygenation of the heart both induce shedding of the coronary endothelial glycocalyx. The processes leading from an oxygen deficit to shedding are unknown. An involvement of resident perivascular cardiac mast cells has been proposed. We hypothesized that either

1. In 3-day-old and 3-week-old spontaneously breathing piglets anaesthetized with Saffan, we have studied ventilatory and cardiovascular responses evoked by 5 min periods of hypoxia (breathing 10 and 6% O2). 2. In 3-day-old piglets both 10 and 6% O2 evoked an increase followed by a secondary fall in

We tested whether hypoxia-induced coronary artery dilatation could be mediated by an increase in adenosine concentration within the coronary artery wall or by an increase in adenosine sensitivity. Porcine left anterior descendent coronary arteries, precontracted with prostaglandin F(2alpha) (10(-5)
