acetylsalicylic acid/hypoxia

BACKGROUND Anticoagulants, e.g. low-molecular weight heparins (LMWHs) and acetylsalicylic acid (ASA) are prescribed to women at risk for pregnancy complications that are associated with impaired placentation and placental hypoxia. Beyond their role as anticoagulants these compounds exhibit direct

OBJECTIVE Treatment with acetylsalicylic acid (ASA) is established for secondary stroke prevention. Recent studies showed neuroprotection of ASA against glutamatergic excitants. The goal of this study was to investigate the time course of neuroprotection of ASA against indirect excitotoxicity by

Study objectives: Chronic intermittent hypoxia (CIH), a hallmark feature of obstructive sleep apnea (OSA), induces accelerated atherogenesis as well as aorta vascular remodeling. Although the cyclooxygenase (COX) pathway has been proposed to contribute to the cardiovascular consequences of OSA, the

Aspirin is the most widely used drug for the secondary prevention of ischemic stroke in patients suffering from diabetes mellitus. Moreover virgin olive oil (VOO) administration exerts a neuroprotective effect in healthy rat brain slices. The aim of the present study was to determine the possible

Diabetes mellitus is a risk factor for cerebrovascular ischemic disease. Aspirin (acetylsalicylic acid) is the most widely used drug for the secondary prevention of thrombotic phenomena. It has been also recently demonstrated that alpha-tocopherol influenced in vitro the antiplatelet effect of

The aim of the present study was to analyze the relative participation of the antiplatelet and the antioxidant effects of acetylsalicylic acid (ASA) and salicylic acid (SA) after a single dose (1 or 10 mg/kg i.p.) in an in vitro model of anoxia in slices of rat brain. After 20 min of drug

Patients suffering from tissue ischemia, who would greatly benefit from angiogenesis-promoting therapies such as hypoxia preconditioned blood-derived secretomes commonly receive oral anticoagulation (OA) and/or have diabetes mellitus (DM). In this study, we investigated the effect of OA

Neu2000 (NEU; 2-hydroxy-5-(2,3,5,6-tetrafluoro-4-trifluoromethyl-benzylamino)-benzoic acid), a recently developed derivative of acetylsalicylic acid and sulfasalazine, potently protects against neuronal cell death following ischemic brain injury by antagonizing NMDA receptor-mediated neuronal

The protective effect of KBT-3022 (ethyl 2-[4,5-bis-(4-methoxyphenyl)thiazol-2-yl]pyrrol-1-ylacetate) , a new cyclooxygenase inhibitor, in cerebral hypoxia and ischemia was studied and compared with those of indomethacin and acetylsalicylic acid (ASA). Oral administration of KBT-3022 (3-100 mg/kg)

Hypoxia-reoxygenation (HR) is a major driver for angiogenesis in atherosclerotic plaques and tumors. Angiogenesis is a multistep process requiring stimulation of proliferation and migration of endothelial cells in response to a number of growth factors, including transforming growth factor (TGFβ1).

Hypoxia–reoxygenation (HR) is a primary driver of angiogenesis in both atherogenesis and tumorigenesis. The main target of hypoxia-driven proangiogenic signaling is adherens junctions responsible for contact inhibition of endothelial cells. We analyzed the effects of hypoxia (8–12 hours) followed by

The main purpose of the present work was to determine whether prostaglandins (PGs) synthetised in the lungs mediate the vasoconstrictor response to acute alveolar hypoxia. Isolated and ventilated lungs of rats were perfused at 37 degrees C with homologous blood at constant-volume, pulsatile inflow,

Acetylsalicylic acid (ASA) reduces the incidence of ischemic stroke mainly through its antithrombotic action; however, it also has a direct neuroprotective effect. The present study was designed to evaluate the effect of ASA on oxidative stress and the activity of nitric oxide synthase (NOS) in an

Triflusal is a fluorinated derivative of acetylsalicylic acid (ASA) with demonstrated antithrombotic activity. Recently, evidence for a neuroprotective effect has been obtained. The aim of this study was to compare the neuroprotective effects of the main metabolite of triflusal

Data are presented on yak platelet ultrastructure (in comparison with human platelets), and on acetylsalicylic acid influence on the platelet ultrastructure and function. The following species features of this animals are associated with their adaptation to high-altitude hypoxia: organization of
