Cancer stem-like cells (CSCs) have been proposed as a key driving force of tumor growth and relapse in colorectal cancer (CRC), and therefore, they are promising targets for cancer therapy. Epidemiological evidence has suggested that the daily use of aspirin reduces overall mortality of CRC and the risk of distant metastasis. We investigated the effect and mechanism of aspirin on CSCs in CRC. Methods: The ratio of CSCs was analyzed after aspirin treatment both in a cell model and patient samples. Chemically modified aspirin and immunoprecipitation were adopted to detect the target proteins of aspirin...

Introduction: Stroke rate and mortality are greater in individuals with end-stage renal disease (ESRD) than in those without ESRD. We examined discrepancies in stroke care in ESRD patients and their influence on mortality. Methods: This is a national record linkage cohort study of hospitalized stroke individuals from 2005 to 2013. Presentation, measures of care quality (admission to stroke unit, swallow assessment, antithrombotics, or thrombolysis use), and outcomes were compared in those with and without ESRD after propensity score matching (PSM)...

BACKGROUND: Previous studies have shown that venous thromboembolism (VTE) is a complication associated with neoplastic disease and major orthopaedic surgery. However, many potential risk factors remain undefined. QUESTIONS/PURPOSES: (1) What proportion of patients develop symptomatic VTE after surgery for long bone metastases? (2) What factors are associated with the development of symptomatic VTE among patients receiving surgery for long bone metastases? (3) Is there an association between the development of symptomatic VTE and 1-year survival among patients undergoing surgery for long bone metastases? (4) Does chemoprophylaxis increase the risk of wound complications among patients undergoing surgery for long bone metastases? METHODS: A retrospective study identified 682 patients undergoing surgical treatment of long bone metastases between 2002 and 2013 at the Massachusetts General Hospital and Brigham and Women's Hospital...

Despite its well-known antithrombotic properties, the effect of aspirin on blood pressure (BP) and hypertension pathology is unclear. The hugely varying doses used clinically have contributed to this confusion, with high-dose aspirin still commonly used due to concerns about the efficacy of low-dose aspirin. Because prostaglandins have been shown to both promote and inhibit T-cell activation, we also explored the immunomodulatory properties of aspirin in hypertension. Although the common preclinical high dose of 100 mg/kg per day improved vascular dysfunction and cardiac hypertrophy, this effect was accompanied by indices of elevated adaptive immunity, renal T-cell infiltration, renal fibrosis, and BP elevation in stroke-prone spontaneously hypertensive rats and in angiotensin II-induced hypertensive mice...

Colorectal cancer (CRC) is the third most prevalent neoplasm worldwide and fourth most frequent reason of cancer-related death throughout the world. About 70% of malignant tumors are related to lifestyle and environmental factors, and better knowledge of their significance might reduce the prevalence of CRC. The cyclooxygenase-2 (COX-2) inhibitory and other direct and indirect pathways of aspirin are translated to inhibition proliferation and enhanced apoptosis of cancer cells. Many studies showed the benefits of aspirin in reducing the risk of CRC development, cancer-related mortality and adenoma prevalence rate in general population, but not in high risk populations...

Herbal remedies and phytochemicals have been used in traditional medicine. Most of the herbs used in human diet have some major effective elements that can affect various pathways in the human body and play a therapeutic role in healing disorders or diseases. Among the inflammatory diseases, worldwide common disorders possess well-known pathways that can be controlled by diet and behavior. There are some well-established targets that are used for anti-inflammatory drugs like cyclooxygenase type 1 and 2 (COX-1 and COX-2), lipoxygenase, prostaglandin D2 receptor, DP1, CRTH2, and so on...

Aspirin (acetylsalicylic acid) inhibits prostaglandin (PG) synthesis by transfer of its acetyl group to a serine residue in the cyclooxygenase (COX) active site. Acetylation of Ser530 inhibits catalysis by preventing access of arachidonic acid substrate in the COX-1 isoenzyme. Acetylated COX-2, in contrast, gains a new catalytic activity and forms 15 R hydroxy-eicosatetraenoic acid (15 R-HETE) as alternate product. Here we show that acetylated COX-2 also retains COX activity, forming predominantly 15 R-configuration PGs (70 or 62% 15 R, respectively, determined using radiolabeled substrate or LC-MS analysis)...

The optimal regimen of antiplatelet therapy for secondary prevention in noncardioembolic ischemic stroke remains controversial. We aimed to determine which regimen was associated with the greatest reduction in adverse outcomes. We analysed prospectively collected data from the Norfolk and Norwich University Hospital Stroke Register. The sample population consisted of 3,572 participants (mean age 74.96 ± 12.67) with ischemic stroke, who were consecutively admitted between 2003 and 2015. Patients were placed on one of three antiplatelet regimens at hospital discharge; aspirin monotherapy, aspirin plus dipyridamole and clopidogrel...

The effect of dual antiplatelet therapy, clopidogrel combined with aspirin, was influenced by CYP2C19 gene mutation and heterogeneity of population. Related studies remained controversial and limited, especially in Chinese. Total 3295 unrelated ACS Chinese patients undergoing percutaneous coronary intervention (PCI) were recruited and followed up to 1 year. Meanwhile, baseline and clinical data were retrieved. CYP2C19*2 and *3 were genotyped by sequencing. Associations of variants and metabolic types with platelet reactivity (PR) were analyzed by a logistic regression model...

BACKGROUND: Coronary artery bypass grafting (CABG) is established treatment for subsets of coronary artery disease (CAD). Observational data have characterised significant progression of native coronary as well as graft vessel disease during longer-term follow-up, potentially reducing the benefit of CABG. We sought to assess longer-term outcomes following CABG by determining rates of repeat coronary angiography, revascularization procedures, and survival. METHODS: Data for all patients undergoing isolated CABG in British Columbia between 2001 and 2009 inclusive, and with follow-up until the end of 2013, were retrieved from the British Columbia Cardiac Registry...

Arachidonic acid (AA 20:4n-6) is an essential component of cell membranes and modulates cell membrane fluidity. AA is metabolized by cyclo-oxygenase (COX), lipoxygenase (LOX) and cytochrome P450 enzymes to form several metabolites that have important biological actions. Of all the actions, role of AA in the regulation of blood pressure and its ability to prevent both type 1 and type 2 diabetes mellitus seems to be interesting. Studies showed that AA and its metabolites especially, lipoxin A4 (LXA4) and epoxyeicosatrienoic acids (EETs), potent anti-inflammatory metabolites, have a crucial role in the pathobiology of hypertension and diabetes mellitus...
