salicylic acid/hypoxia

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

AtR8 lncRNA was previously identified in the flowering plant Arabidopsisthaliana as an abundant Pol III-transcribed long non-coding RNA (lncRNA) of approximately 260 nt. AtR8 lncRNA accumulation is responsive to hypoxic stress and salicylic acid (SA) treatment in roots,

Carbon monoxide poisoning produces both immediate and delayed neuronal injury in selective regions of the brain that is not readily explained on the basis of tissue hypoxia. One possibility is that cellular injury during and after CO poisoning is related to the production of reactive oxygen species

OBJECTIVE People travelling to high altitude for occupational, recreational or religious purposes are mostly healthy and fit but sometimes they use drugs for common ailments like influenza, acute mountain sickness or chronic disease like diabetes. Limitation of oxygen at high altitude may compromise

The utility of anti-angiogenic strategies for cancer control is strongly compromised by hypoxia-driven phenotypic changes in cancer cells, which make cancer cells more invasive and more prone to give rise to metastases. A key mediator of this phenotypic shift is the transcription factor

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

In solid tumors the hypoxic environment can promote tumor progression and resistance to therapy. Recently, acetylsalicylic acid a major component of analgesic drugs and its metabolite salicylic acid (SA) have been shown to reduce the risk of colon cancer, but the mechanisms of action remain still

Autophagy involves massive degradation of intracellular components and functions as a conserved system that helps cells to adapt to adverse conditions. In mammals, hypoxia rapidly stimulates autophagy as a cell survival response. Here, we examine the function of autophagy in the regulation of the

Jaborandi seedlings were subjected to different treatments in order to study the induction of pilocarpine in the leaves. In addition four extraction methods were assessed to extract the alkaloid from dried leaves. The highest yielding extraction and recovery was observed when dried leaves were first

BACKGROUND Platelet activation has been demonstrated in experimental and clinical models of ischemia-reperfusion, but the underlying mechanism is still unclear. We mimicked the ischemia-reperfusion model in vitro by exposing platelets to anoxia-reoxygenation (A-R) and evaluated the role of oxygen

Agrobacterium tumefaciens-derived crown galls of Arabidopsis (Arabidopsis thaliana) contain elevated levels of unsaturated fatty acids and strongly express two fatty acid desaturase genes, ω3 FATTY ACID DESATURASE3 (FAD3) and STEAROYL-ACYL CARRIER PROTEIN Δ9-DESATURASE6 (SAD6). The fad3-2 mutant

Since hypobaric hypoxia significantly affects metabolic characteristics of intestinal flora, which plays an important role in the biotransformation of aspirin, high altitudes may influence the pharmacokinetics and therapeutic effects of aspirin in the intestines. In the present study, to test

WRKY62 is a transcriptional repressor regulated downstream of WRKY45, a central transcription factor of the salicylic acid signaling pathway in rice. Previously, WRKY62 was reported to regulate defense negatively. However, our expressional analysis using WRKY62-knockdown rice indicated that WRKY62
