Ingia / Ingia

We have investigated the action of the product of the enzyme NADPH oxidase; hydrogen peroxide (H2O2), on the first phase of the hypoxic contraction, prostaglandin F2 alpha (PGF2 alpha)-induced contractions and potassium chloride (KCl)-induced contractions, in isolated rat pulmonary arteries in a

Infants who suffer perinatal brain injury, including those with encephalopathy of prematurity, are prone to chronic neurological deficits, including epilepsy, cognitive impairment, and behavioral problems, such as anxiety, inattention, and poor social interaction. These deficits, especially in

Ingia / Ingia

Hypoxia-ischaemia brain damage (HIBD) is a major type of perinatal brain injury in newborns. In this study, we investigate the short- and long-term neuroprotective effects of Diazepam on neonatal rats with HIBD and the potential mechanisms underlying its protective effects. Seven-day-old

Ingia / Ingia

OBJECTIVE In the ovine fetus subjected to 24 hours of hypoxia, urinary flow is normal within a few hours from the onset of hypoxia and there is a maintained inhibition of swallowing. We hypothesized that 4 days of fetal hypoxia would lead to polyhydramnios. METHODS Five late-gestation fetal sheep

Ingia / Ingia

BACKGROUND This study was undertaken to investigate the expression of hypoxia-inducible factor-1α (HIF-1α) in rat cerebral cortex and the effects of β-sodium aescinate (SA) administration after return of spontaneous circulation (ROSC). METHODS SIXTY RATS WERE DIVIDED INTO THREE GROUPS: SA group,

Chronic hypoxia inhibits postnatal maturation of porcine intrapulmonary artery relaxation.

Ingia / Ingia

Neonatal pulmonary hypertension is associated with increased pulmonary vascular reactivity. We studied the responses of isolated porcine intrapulmonary arteries after exposure of piglets to chronic hypobaric hypoxia (CHH) from 0 to 2.5, 3 to 6, or 14 to 17 days of age. CHH inhibited the postnatal

Effects of perinatal exposure to hypoxia upon the pulmonary circulation of the adult rat.

Ingia / Ingia

The hypothesis on Fetal and Infant Origins of Adult Disease proposes that an altered in utero environment may impair fetal development and physiological function, increasing susceptibility to disease in adulthood. Previous studies demonstrated that reduced fetal growth predisposes to adult

Age dependence of tolerance to anoxia and changes in cytosolic calcium in rabbit renal proximal tubules.

Ingia / Ingia

Calcium(Ca2+)-dependent processes mediate, in part, anoxic cell injury. These may account for the difference in sensitivity to anoxia between certain immature and mature renal cells. To address this question, we studied the effects of anoxia on cytosolic free Ca2+ concentration ([Ca2+]i), cell

Evidence for hypoxia-induced, programmed cell death of cultured neurons.

Ingia / Ingia

Apoptosis, a form of cell death ("programmed" cell death) in which the nucleus and cytoplasm shrink and often fragment, serves to eliminate excessive or unwanted cells during remodeling of embryonic tissues, during organ involution, and in tumor regression. In acute pathological states, such as

Mechanisms of aortic smooth muscle hyporeactivity after prolonged hypoxia in rats.

Ingia / Ingia

The aim of this study was to determine whether the effects of hypoxia on aortic contractility reflect a decrease in smooth muscle activation [phosphorylation of the 20-kDa myosin regulatory light chain (LC(20))], the capacity for myofibrillar ATP hydrolysis (mATPase activity), or both. Our results

Chronic exposure to hypoxia attenuates contractile responses in rat airways in vitro: a possible role for nitric oxide.

Ingia / Ingia

We investigated the effect of chronic hypoxia (10% O(2) for 14 days) on airway responsiveness in rats. Chronic hypoxia significantly (P<0. 05, P<0.01, P<0.01, respectively) attenuated contractions evoked by methacholine (10(-9)-3x10(-4) M), endothelin-1 (10(-10)-3x10(-7) M) and potassium chloride

Prostaglandin mediated relaxation of coronary artery strips under hypoxia.

Ingia / Ingia

Strips of beef coronary branch arteries, maintained in vitro, respond to decreased PO2 in the bathing medium with relaxations which are much attenuated by pretreatment with indomethacin or aspirin. It was determined that these hypoxia-induced relaxations are sustained until strips are returned to an

We have examined the effect of endothelin-1, sarafotoxin-6C, big-endothelin-1 and other agents on perfused lungs from chronically hypoxic rats. Increases in pulmonary perfusion pressure induced by big-endothelin-1, endothelin-1, phenylephrine and potassium chloride were enhanced in hypoxic lungs,
