INTRODUCTION: Optimal vascular function is a hallmark of cardiovascular health. Specifically, the balance of vasoconstricting and vasodilating substances is recognized as a marker of vascular health. One of the greatest challenges to vascular health and vasodilatory balance is tumor necrosis factor alpha (TNFα) mediated inflammation. Uncovering effective strategies that maintain a vascular environment that is more vasodilatory and anti-thrombotic in the face of an inflammatory challenge is favorable...

BACKGROUND: The APC trial showed that cyclooxygenase-2 (Cox-2) inhibitor, celecoxib, decreased adenoma development in patients at high risk for colorectal cancer. A prospectively planned analysis of the APC trial tested the hypothesis that expression of target enzymes in adenomas removed before beginning study treatment would identify individuals at high risk of adenoma development, and/or predict response to Cox-2 inhibition. METHODS: Pre-treatment adenomas were examined using immunohistochemistry (IHC) to assess expression of Cox-2 (high vs...

Epileptic seizures constitute an important problem in pediatric neurology during the developmental period. The frequency and nosological significance of seizures, as well as their association with epileptogenesis, may be related to underlying mechanisms such as neuroinflammation. Those mechanisms of response activate inflammatory molecules induced in the neurons, activated glial cells and endothelial cells via the key HMGB1/TLR4 pathway. In this study, the drug celecoxib (CCX) was used as a blocker of the cyclooxygenase 2 (COX-2) and HMGB1/TLR-4 pathways...

Cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LOX) and microsomal prostaglandin E synthase-1 (mPGES-1)-derived eicosanoids play an essential role in human inflammatory disorders. Here, we investigated whether inhibition of COX-2/mPGES-1 and 5-LOX in macrophages by leonurine ameliorates monosodium urate (MSU) crystal-induced inflammation. Virtual screening assay and in vitro enzyme inhibition assay showed that leonurine was a potential inhibitor of COX-2, mPGES-1 and 5-LOX. Compared with COX-2 inhibitor celecoxib, leonurine (30 mg/kg) significantly decreased ankle perimeter, gait score and neutrophil number in synovial fluid in MSU crystal-treated rats, accompanied with the decreased expression of COX-2, mPGES-1 and 5-LOX and production of prostaglandin E2 (PGE2 ) and leukotriene B4 (LTB4 ) in the synovial fluid macrophages...

Based on systematic surveillance of more than 110 medical journals, 247 studies met criteria as POEMs (patient-oriented evidence that matters) in 2017. Members of the Canadian Medical Association identified 20 of these POEMs as most relevant to practice. This article reviews the clinical questions and bottom-line answers from these studies. Blood pressure should be measured after a period of rest, using a bare arm, and orthostatic blood pressure is more predictive when measured after one minute of standing rather than three minutes...

Selective COX-2 inhibitors are most widely used analgesic and anti-inflammatory drugs; however, its maximal use is highly associated with various serious abnormal cardiovascular events. Beraprost sodium (BPS), prostacyclin analogue has been shown to vasodilatory, antiplatelates, anti-inflmmatory, and antioxidant activity. The objective of the present study was to evaluate the effect of BPS on celecoxib cardiotoxicity in rats. Toxicity was induced in male Albino rats (250-280 g) by celecoxib (100 mg/kg/day)...

BACKGROUND AND AIMS: In rheumatoid arthritis, the control of both disease activity and standard cardiovascular (CV) risk factors is expected to attenuate the increased CV risk. Evidence that brain-derived neurotrophic factor (BDNF) plays a role in vascular biology led us to investigate the vascular BDNF pathway in arthritis rats as well as the interaction between endothelial nitric oxide (NO) and BDNF production. METHODS: The aortic BDNF pathway was studied in rats with adjuvant-induced arthritis, (AIA) using Western blot and immunohistochemical analysis...

OBJECTIVE: Despite numerous treatments for epilepsy, over 30% of patients remain resistant to available antiseizure drugs (ASDs). Thus, there is a strong need for more effective ASDs for these individuals. Early ASD discovery has historically relied on acute in vivo seizure models (maximal electroshock, subcutaneous pentylenetetrazol, 6 Hz), which lack the pathophysiology that defines chronic epilepsy. Etiologically relevant rodent models of pharmacoresistant epilepsy exist (eg, phenytoin (PHT)- and lamotrigine (LTG)-resistant amygdala-kindled rat and focal kainic acid mouse), but these models are resource- and labor-intensive and thus unsuitable for frontline ASD discovery...

To establish alternative targeted therapies against triple negative (TN) breast cancer, (1) the energy metabolism and (2) the sensitivity of cell growth, migration and invasiveness towards metabolic, canonical and NSAID inhibitors was analyzed in MDA-MB-231 and MDA-MB-468, two TN metastatic breast cancer cell lines, under both normoxia (21% O2) and hypoxia (0.1% O2). For comparative purposes, analysis was also carried out in the less-metastatic breast MCF-7 cancer cells. Under normoxia, oxidative phosphorylation (OxPhos) was significantly higher (2-times) in MDA-MB-468 than in MDA-MB-231 and MCF-7 whereas their glycolytic fluxes and OxPhos and glycolytic protein contents were all similar...

Study methodologies of supersaturated state are fast developing as pharmaceutical industry is adopting supersaturating drug delivery systems (SDDS) to overcome solubility issue of drugs. The 'parachute' of sobriquet 'spring-and-parachute' which indicates delayed or slowed intraluminal precipitation of drug from SDDS, is of immense importance to formulation scientists since optimal attainment of 'parachute' governs the success of SDDS in stabilizing supersaturated state that ensues in enhancement of bioavailability...

INTRODUCTION: Adult people with hemophilia (PWH) mainly use Factor VIII/Factor IX (FVIII/FIX) to lessen chronic articular pain, followed in frequency by nonsteroidal anti-inflammatory drugs. Analgesics are used by only one-third of adult PWH. Limitations in activities of daily living are encountered in the large majority of PWH, and most describe pain as affecting their state of mind. A review of the literature on their treatment is important because chronic pain in adult PWH is often undertreated or wrongly treated, causing psychological problems for these patients...

Synovial inflammation is an important characteristic of arthritic disorders like osteoarthritis and rheumatoid arthritis. Orally administered non-steroidal anti-inflammatory drugs (NSAIDs) such as celecoxib are among the most widely prescribed drugs to manage these debilitating diseases. Intra-articular delivery in biodegradable in situ forming hydrogels overcomes adverse systemic effects and prolongs drug retention in the joint. In this study two formulations of celecoxib (40 mg/g and 120 mg/g) in a propyl-capped PCLA-PEG-PCLA triblock copolymer were sequentially evaluated in a multiple LPS challenge equine synovitis model...
