Arachidonic acid (AA) metabolites control cell proliferation, among other physiologic functions. RAW 264.7 macrophages can metabolise AA through the cyclooxygenase and lipoxygenase (LOX) pathways. We aimed to study the role of AA-metabolites derived from 5-LOX in the control of RAW 264.7 macrophage growth. Our results show that zileuton, a specific 5-LOX(More)
Eicosanoids participate in the regulation of cellular proliferation. Thus, we observed that prostaglandin E(2) interaction with membrane receptors is involved in the control of 3T6 fibroblast growth induced by serum. However, our results suggested that another arachidonic acid pathway might be implicated in these events. Our results show that 3T6(More)
Previous studies have demonstrated that arachidonic acid (AA) metabolites released by the cyclooxygenase pathway is involved in serum-induced 3T6 fibroblast cycle progression and proliferation. However, these results also suggest that other AA cascade pathways might be involved. Recently, we also described the role of hydroxyeicosatetraenoic acids, which(More)
Hydroxyeicosatetraenoic acids (HETEs) have numerous physiological effects, including modulation of cell proliferation and differentiation. However, little is known about the selective effects of HETE enantiomers on cell proliferation and cell signalling pathways involved in the regulation of cell growth. Furthermore, information on epithelial and(More)
INTRODUCTION Approximately 80-85% of lung cancer patients are diagnosed with non-small-cell lung cancer (NSCLC), of which 50% of patients present with advanced or metastatic disease. The objective of this study was to describe treatment patterns, use of resources and costs associated with treating advanced or metastatic NSCLC patients in Spain. METHODS A(More)
Prostaglandins (PGs) and leukotrienes (LTs) derived from arachidonic acid (AA) are potent mediators of inflammation and cell proliferation. Dietary intake of eicosapentaenoic acid (EPA) appears beneficial to both inflammatory processes and cell proliferation. However, there is no clear mechanism explaining these effects. In this study, we investigated the(More)
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a form of chronic fibrosing interstitial pneumonia characterized by progressive worsening of dyspnea and lung function, with a poor prognosis. The objective of this study was to determine treatment patterns, resource use and costs of managing Spanish patients with IPF. METHODS A three-round Delphi(More)
INTRODUCTION Various international studies have shown that fludarabine is effective, safe, and efficient for treating B-cell chronic lymphocytic leukemia (B-CLL). The purpose of the present study was to carry out a cost-minimization analysis for two alternative forms of fludarabine (oral and intravenous) used to treat B-CLL in Spain. METHODS The presence(More)
OBJECTIVE To compare the costs of treating osteoarthritis (OA) pain using combination tramadol/paracetamol tablets, Non-Steroidal Anti-Inflammatory Agents (NSAID) alone or NSAID plus proton pump inhibitors (PPI) from the perspective of the Spanish National Health System. METHODS A decision-analytical model was constructed to analyze the cost associated(More)
OBJECTIVE The aim of this study is to conduct a cost-effectiveness analysis of 5-fluorouracil 0.5%/salicylic acid 10% (5-FU/SA) in the treatment of isolated hyperkeratotic actinic keratosis lesions in Spain. METHODS An analytical decision-making model was constructed to compare whether 5-FU/SA was a cost-effective option compared with cryotherapy from the(More)
