BACKGROUND: β-d-Glucans are polysaccharides found in the cell walls of yeasts, such as Saccharomyces cerevisiae, and they have been studied because of their beneficial effects on health, mainly in terms of immunomodulation. However, information on the action of these polymers on vascular and platelet function is still scarce. This study evaluate the effect of (1→3) (1→6) β-d-glucan (βG-Sc) and its carboxymethylated derivative (CM-G) on vascular and platelet function in rats. METHODS: The animals received daily oral treatments with βG-Sc (20mg/kg) and CM-G (20mg/kg) for eight days...

We aimed to identify the prevalence of acetylsalicylic acid (ASA) nonresponse in patients after coronary artery bypass graft (CABG) surgery and the possible consequences for the rate of major cardiovascular events. This prospective, observational, bicentric cohort study was conducted in two German University hospitals. A total of 400 patients (200 in each study center) undergoing elective CABG surgery were enrolled after written informed consent. Platelet function was analyzed on day 3 (d3) and day 5 (d5) postoperatively following stimulation with arachidonic acid (ASPItest) and with thrombin receptor-activating peptide 6 (TRAPtest) using multiple electrode aggregometry (Multiplate)...

Resistance to acetylsalicylic acid (ASA) in patients with coronary artery disease is a poor predictor for the development of atherothrombotic complications. In 277 patients with coronary artery disease suffered uncomplicated coronary angioplasty with stent implantation, we was estimated arachidon-induced platelet aggregation during treatment with acetylsalicylic acid by bedside VerifyNow Assay test at 28-90 days after the intervention. It was found that 18.9% of the 144 patients receiving a combination of ASA 75 mg with 15...

Aspirin or acetylsalicylic acid (ASA) is a medicine used to treat pain, fever, and inflammation. Here, we for the very first time reported the genome-wide transcriptional profiling of aspirin-regulated genes in Streptococcus pneumoniae in the presence of 5 mM aspirin in chemically-defined medium (CDM) using microarray analysis. Our results showed that expression of several genes was differentially expressed in the presence of aspirin. These genes were further grouped into COG (Clusters of Orthologous Groups) functional categories based on the putative functions of the corresponding proteins...

REVIEW
Anna M Feldweg
Food-dependent, exercise-induced anaphylaxis is a disorder in which anaphylaxis develops most predictably during exercise, when exercise takes place within a few hours of ingesting a specific food. IgE to that food should be demonstrable. It is the combination of the food and exercise that precipitates attacks, whereas the food and exercise are each tolerated independently. Recently, it was demonstrated that exercise is not essential for the development of symptoms, and that if enough of the culprit food is ingested, often with additional augmentation factors, such as alcohol or acetylsalicylic acid, symptoms can be induced at rest in the challenge setting...

BACKGROUND: Cardiovascular disease is the leading cause of mortality and morbidity in developed countries, including Poland. Antithrombotic drugs play a crucial role in the management of acute coronary syndromes (ACS). Recent clinical trials have demonstrated the efficacy and safety profiles of new antiplatelet and anticoagulant agents, which may be used as add-on therapy or replacements for older drugs. The EPICOR: (long-t E: rm follow-u P: of antithrombotic management patterns I: n acute COR: onary syndrome patients) is a prospective international observational study (NCT01171404) designed to describe the use of antithrombotic management strategies for the treatment of ACS during the acute phase and over a follow-up period of up to 2 years from the index event...

Using density functional theory, we investigate the adsorption properties of acetylsalicylic acid (aspirin) on the outer surfaces of a (10,0) carbon nanotube (CNT) and a (8,0) triazine-based graphitic carbon nitride nanotube (CNNT). The adsorption energies for the CNNT and CNT are 0.67 and 0.51 eV, respectively, and hence, the aspirin molecule binds more strongly to the CNNT. The stronger adsorption energy for the binding to the CNNT is ascribed to the high reactivity of its nitrogen atoms with high electron affinity...

BACKGROUND: The beneficial use of dual antiplatelet therapy (DAPT) with acetylsalicylic acid (ASA) and P2Y12 õinhibitors has been established for patients after acute coronary syndrome (ACS). However, the optimal duration of DAPT is under debate. The aim of the present study was to investigate the long-term utilization and clinical outcome of clopidogrel, prasugrel, and ticagrelor in patients with ACS from 2009 to 2014 in Austria. METHODS: We analysed data from 13 Austrian health insurance funds for the years 2009 to 2014, on 72,676 patients with a hospital discharge diagnosis of ACS...

Although aspalatone (acetylsalicylic acid maltol ester) is recognized as an antithrombotic agent with antioxidative and antiplatelet potential; its efficacy in preventing endothelial dysfunction is not known. In this study, we examined the antiangiogenic, antioxidative, and anti-inflammatory effect of aspalatone in human aortic endothelial cells (HAECs). Specifically, the effect of aspalatone on VEGF-induced HAECs growth, migration, tube formation, and levels of lipid peroxidation-derived malondialdehyde (MDA) was examined...

β-carotenoid hydroxylase (CHYB) is an important rate-limiting enzyme in the biosynthesis of plant carotenoid. In this study, chyb1 and chyb2, two gene families in Dunaliella viridis were obtained by RNA-seq. The fragment of promoters of CHYB family genes, 1 080 bp for chyb1 (GenBank No. KY012338) and 1 155 bp for chyb2 (GenBank No. KY012339) were cloned by the Genome Walking Technology, respectively. Cis-acting elements of two promoters were analyzed by Plantcare soft. The results show that the chyb1 gene promoter contains more cis-acting elements in responses to abiotic stresses, such as methyl jasmonate, arachidonic acid, acetylsalicylic acid, and so on...

The interaction of clinically relevant microorganisms is the focus of various studies, e.g. the interaction between the pathogenic yeast, Candida albicans, and the bacterium, Pseudomonas aeruginosa. During infection both release arachidonic acid, which they can transform into eicosanoids. This study evaluated the production of prostaglandin E2, prostaglandin F2α and 15-hydroxyeicosatetraenoic acid by biofilms of P. aeruginosa and C. albicans. The influence of co-incubation, acetylsalicylic acid and nordihydroguaiaretic acid on biofilm formation and eicosanoid production was evaluated...

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequent triggers of drug hypersensitivity with NSAIDs-induced urticaria/angioedema (NIUA) the most common phenotype. Loss of hypersensitivity has been reported for IgE-mediated reactions; however it has not been assessed in non-immunological reactions such as NIUA. We evaluated NSAID-hypersensitivity over time in NIUA patients. METHODS: Patients confirmed as NIUA by positive drug provocation test (DPT) with acetylsalicylic acid (ASA) during 2005-2012 (V1) were included (n=38)...

BACKGROUND AND OBJECTIVES: Individuals who develop drug hypersensitivity reactions (DHRs) to chemically unrelated nonsteroidal anti-inflammatory drugs (NSAIDs) are considered cross-hypersensitive. The hallmark for this classification is that the patient presents a reaction after intake of or challenge with acetylsalicylic acid (ASA). Whether patients react to 2 or more NSAIDs while tolerating ASA remains to be studied (selective reactions, SRs). Objective: To identify patients with SRs to 2 or more NSAIDs including strong COX-1 inhibitors...
