1. InteraÃÃo das vias da ciclo-oxigenase-2 e da hemeoxigenase-1 / biliverdina / monÃxido de carbono no controle da nocicepÃÃo e da inflamaÃÃo / Interaction between cyclooxygenase-2 and heme oxygenase-1 / biliverdin / carbon monoxide pathways in nociception and inflammation control in rats and mice.
Introduction: Heme oxygenase-1 (HO-1) plays a preventive role in oxidative stress. In contrast, COX-2 is involved in the pathogenesis of many inflammatory diseases and COX-2 selective inhibition has been shown to be effective in reversing inflammation without gastric side effects. However, serious cardiovascular effects of some selective COX-2 inhibitors eme

2. Renal effects promoted by myotoxins and lectins isolated from the snake venoms of Bothrops jararacusu and Bothrops moojeni. The role of cyclooxigenase and endothelin / Efeitos renais de miotoxinas e lectinas purificadas dos venenos das serpentes Bothrops jararacussu e Bothrops moojeni. Papel da ciclooxigenase e endotelina
Acute renal failure is one of the most common systemic complications after snakebite. However, its pathogenesis remains obscure. In this study, we evaluated the renal effects of Bothrops jararacussu myotoxins I and II (Bthtx-I Lys 49 and BthtxII, Asp 49), Bothrops moojeni myotoxin I and the lectins from Bothrops moojeni and Bothrops jararacussu. Attempting t

3. Estudo clínico comparativo de dose única pré-operatória de 50mg de rofecoxib ou diclofenado sódico no controle da dor após tratamento endodôntico
Pain management following endodontic therapy is an essential part of patient treatment. Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase enzymes that abolish the effects of prostaglandins and consequently exert potent anti-inflammatory and analgesic activity. The aim of the present pilot study was to test the efficacy of prior drug admini

4. Lipid mediator interplay: resolvin D1 attenuates inflammation evoked by glutathione-conjugated lipid peroxidation products
Non-enzymatic oxidation of cellular lipids, one of the characteristic features of inflammation, leads to formation of highly reactive and toxic α,β-unsaturated aldehydes, such as 4-hydroxy-trans-2-nonenal (HNE). Conjugation of HNE with reduced glutathione (GS-HNE) is widely believed to represent a form of detoxification. The study by Spite et al. in the cu

5. The spinal biology in humans and animals of pain states generated by persistent small afferent input
Behavioral models indicate that persistent small afferent input, as generated by tissue injury, results in a hyperalgesia at the site of injury and a tactile allodynia in areas adjacent to the injury site. Hyperalgesia reflects a sensitization of the peripheral terminal and a central facilitation evoked by the persistent small afferent input. The allody

6. Systemic biosynthesis of prostacyclin by cyclooxygenase (COX)-2: The human pharmacology of a selective inhibitor of COX-2
Prostaglandins (PG) are synthesized by two isoforms of the enzyme PG G/H synthase [cyclooxygenase (COX)]. To examine selectivity of tolerated doses of an inhibitor of the inducible COX-2 in humans, we examined the effects of celecoxib on indices of COX-1-dependent platelet thromboxane (Tx) A2 and on systemic biosynthesis of prostacyclin in vivo.
