An update on the relationships between rheumatoid arthritis and atherosclerosis
2010
Rheumatoid arthritis is a chronic inflammatory disease. Cardiovascular events are the most important cause of mortality and morbidity in patients with rheumatoid arthritis. Beyond the traditional cardiovascular risk factors, chronic systemic inflammation has been shown to be a crucial factor in atherosclerosis development and progression from endothelial dysfunction to plaque rupture and thrombosis. Many studies have shown that atherosclerosis is not a passive event like accumulation of lipids in the vessel walls; by contrast, it represents an active inflammation of the vessels. Inflammatory cells such as macrophages, monocytes and T cells play important roles in the development of both rhe…
Celecoxib for recurrent sclerouveitis after syphilitic panuveitis. A case report
2011
Purpose To report a case of recurrent ocular inflammation after optimal therapy of bilateral syphilitic panuveitis responding to oral celecoxib. Methods A case report was conducted. Results A 76-year-old man presented with painful blurry vision in both eyes. Ocular examination disclosed bilateral panuveitis. Serological testing confirmed blood and cerebrospinal fluid syphilitic involvement. After 2 weeks of intravenous penicillin therapy, recurrent episodic sclerouveitis was observed. Conclusion Ocular inflammation after healing of infectious uveitis is a rare ophthalmic sequela. In an immunocompetent patient, either re-infection or immune uveitis should be evoked. Non-steroidal therapeutic…
Treatment with a CO-releasing molecule (CORM-3) reduces joint inflammation and erosion in murine collagen-induced arthritis.
2008
Contains fulltext : 70589.pdf (Publisher’s version ) (Closed access) OBJECTIVE: CO-releasing molecules (CO-RMs) are a novel class of anti-inflammatory agents. We have examined the possible therapeutic effects of CORM-3 in collagen-induced arthritis (CIA). METHODS: Arthritis was induced in DBA-1/J mice by type II collagen. Animals were treated with CORM-3 (5 and 10 mg/kg/day, intraperitoneally) or the inactive compound iCORM-3 (10 mg/kg/day, intraperitoneally) unable to release CO, from days 22 to 31. Production of anti-type II collagen antibodies, cytokines and cartilage olimeric matrix protein (COMP) was evaluated by enzyme-linked immunosorbent assay, and prostaglandin E(2) (PGE(2)) by rad…
The pain threshold of high-threshold mechanosensitive receptors subsequent to maximal eccentric exercise is a potential marker in the prediction of D…

Background Delayed-onset muscle soreness (DOMS) refers to dull pain and discomfort in people after participating in exercise, sport or recreational physical activities. The aim of this study was to detect underlying mechanical thresholds in an experimental model of DOMS. Methods Randomised study to detect mechanical pain thresholds in a randomised order following experimentally induced DOMS of the non-dominant arm in healthy participants. Main outcome was the detection of the pressure pain threshold (PPT), secondary thresholds included mechanical detection (MDT) and pain thresholds (MPT), pain intensity, pain perceptions and the maximum isometric voluntary force (MIVF). Results Twenty volun…
THE ROLE OF NEUROMODULATORS (SUBSTANCE P AND CALCITONINE GENE-RELATED PEPTIDE) IN THE DEVELOPMENT OF NEUROGENIC INFLAMMATION IN THE ORAL MUCOSA
2004
Vatous observations carried out in the course of the years have shown that certain neuropeptides have a possible role to play as inflammation mediators. The substances on which attention has been principally focused are: substance P, calcitonin gene-related peptide, capsaicin an histamine. Knowledge acquired in this field, however, does not yet permit us to sufficiently clarify the role, not to speak of the possible action mechanism, on the basis of which these neuropeptides act, although it is confirmed that these substances have been found first in laboratory animals and later also in human tissues in the course of experimentally induced neurogenic inflammation. The need to know more and …
Role of the NF-kB pathway and nitric oxide in mammary gland involution after weaning. Implications in breast cancer
2013
INTRODUCCIÓN La glándula mamaria es un órgano dinámico que alcanza su máximo desarrollo funcional con la lactancia, momento en el cual, a través de la producción de leche, aporta nutrientes y protección inmunológica a las crías de los mamíferos. Cuando la lactancia finaliza con el destete, el exceso de tejido glandular debe desaparecer y la glándula sufre una extensa remodelación hasta alcanzar nuevamente un estado pre-gestacional, preparada para un nuevo ciclo. La involución del tejido mamario es un proceso complejo durante el cual se suceden de forma coordinada una serie de eventos como la muerte de las células epiteliales secretoras, la proliferación de tejido adiposo circundante y la re…
Anti-inflammatory properties of an aldehydes-enriched fraction of grapefruit essential oil
2023
Chronic inflammation is linked to the development of numerous diseases and is accompanied by increased cytokine secretion. Macrophages provide a first line of defense against pathogens that under inflammatory stimuli release pro-inflammatory cytokines. The essential oil (EO) fractions obtained from Citrus spp. rich in different compounds have gained the attention of both researchers and users during the last decades. In particular, grapefruit (Citrus paradisi) peel is rich in phenolics and flavonoids with several health benefits, including anti-inflammatory actions. Additionally, its EO consists of a large number of compounds such as monoterpenes, sesquiterpenes, alcohols, aldehydes, esters…
The Sick Adipose Tissue: New Insights Into Defective Signaling and Crosstalk With the Myocardium
2021
Adipose tissue (AT) biology is linked to cardiovascular health since obesity is associated with cardiovascular disease (CVD) and positively correlated with excessive visceral fat accumulation. AT signaling to myocardial cells through soluble factors known as adipokines, cardiokines, branched-chain amino acids and small molecules like microRNAs, undoubtedly influence myocardial cells and AT function via the endocrine-paracrine mechanisms of action. Unfortunately, abnormal total and visceral adiposity can alter this harmonious signaling network, resulting in tissue hypoxia and monocyte/macrophage adipose infiltration occurring alongside expanded intra-abdominal and epicardial fat depots seen …
Effect of SGLT-2 inhibition in abdominal aortic aneurysm development. Role of RORa in adipose tissue inflammation associated to obesity
2021
El aneurisma aórtico abdominal (AAA) se define como una dilatación local de la arteria aorta a nivel abdominal cuya consecuencia más grave es su ruptura si no se detiene su crecimiento y progresión. Los rasgos patológicos del AAA incluyen un estado inflamatorio crónico que afecta a la pared vascular de la aorta, una degradación progresiva de la matriz extracelular y un aumento en la neovascularización. Esta enfermedad presenta una elevada tasa de mortalidad y en la actualidad el único tratamiento efectivo que se conoce es la intervención quirúrgica, pero no está indicada en pacientes asintomáticos o que presentan un aneurisma de reducido tamaño. Por ello, es fundamental encontrar nuevas est…
Depletion of
2020
Child obesity constitutes a risk factor for developing insulin resistance which, if sustained, could lead to more severe conditions like type 2 diabetes (T2D) in adulthood. Our study identified previously unknown species whose depletion (Blautia luti and Blautia wexlerae) is associated with insulin resistance in obese individuals. Our results also indicate that these bacterial species might help to reduce inflammation causally linked to obesity-related complications. Childhood is considered a window of opportunity to tackle obesity. These new findings provide, therefore, valuable information for the future design of microbiota-based strategies for the early prevention of obesity-related com…
