Bone loss is asymptomatic and will progress without pain and other symptoms until the occurrence of a fracture. The occurrence of a breaking bone induce acute pain determined and supported by a mechanical, inflammatory and neuropathic component. Very often the acute component evolves in a chronic musculoskeletal component. Overall objectives of the analgesic therapy can be summarized in pain relief, improving sleep, improve mobility, reduce anxiety, emotional component and depression. Osteoporosis is predominantly a condition of the elderly, more likely to have coexisting cardiovascular disease and age-related decline in renal function, receiving treatment for one or more comorbid conditions, taking multiple medications...

Depression is one of the most common psychiatric disorders. Chronic inflammatory response has been viewed as a key factor in depression. Acupuncture in Chinese medicine has been shown to be an effective treatment for depression. In the present study, we investigated the mechanism underlying antidepressant effect of acupuncture. The rats were subjected to chronic unpredictable mild stress (CUMS) for 28days to induce depressive-like behaviors. Acupuncture treatment was applied once every other day during the 28-day stress period...

BACKGROUND: Prostaglandin E2 (PGE2)-involved neuroinflammatory processes are prevalent in several neurological conditions and diseases. Amyloid burden is correlated with the activation of E-prostanoid (EP) 2 receptors by PGE2 in Alzheimer's disease. We previously demonstrated that electromagnetic field (EMF) exposure can induce pro-inflammatory responses and the depression of phagocytosis in microglial cells, but the signaling pathways involved in phagocytosis of fibrillar β-amyloid (fAβ) in microglial cells exposed to EMF are poorly understood...

DHA is a key nutritional n-3 PUFA and needs to be supplied by the human diet. DHA is found in significant amounts in the retinal and neuronal cell membranes due to its high fluidity. Indeed, DHA is selectively concentrated in the synaptic and retinal membranes. DHA is deemed to display anti-inflammatory properties and to reduce the risk of CVD. Consumption of larger amounts of DHA appears to reduce the risk of depression, bipolar disorder, schizophrenia and mood disorders. Conversely, it has been shown that loss of DHA from the nerve cell membrane leads to dysfunction of the central nervous system in the form of anxiety, irritability, susceptibility to stress, dyslexia, impaired memory and cognitive functions, and extended reaction times...

BACKGROUND Depressive disorder, including recurrent type (rDD), is accompanied by increased oxidative stress and activation of inflammatory pathways, which may induce DNA damage. This thesis is supported by the presence of increased levels of DNA damage in depressed patients. Such DNA damage is repaired by the base excision repair (BER) pathway. BER efficiency may be influenced by polymorphisms in BER-related genes. Therefore, we genotyped nine single-nucleotide polymorphisms (SNPs) in six genes encoding BER proteins...

Tissue injury is known to produce inflammation and pain. Synaptic potentiation between peripheral nociceptors and spinal lamina I neurons has been proposed to serve as a trigger for chronic inflammatory pain. Gastrodin is a main bioactive constituent of the traditional Chinese herbal medicine Gastrodia elata Blume, which has been widely used as an analgesic since ancient times. However, its underlying cellular mechanisms have remained elusive. The present study demonstrated for the first time that gastrodin exhibits an analgesic effect at the spinal level on spontaneous pain, mechanical and thermal pain hypersensitivity induced by peripheral inflammation, which is not dependent on opioid receptors and without tolerance...

Studying the effect of ozone therapy on the course of pyoinflammatory processes with diabetes mellitus in the experiment, conducted on 30 white 24-30 month rats, weight 300-450 gr with purulent-inflammatory processes, it was found out that diabetes, which was simulated by subcutaneous injection of alloxan, causes mosaic disturbances of hemostasis system in the presence of pyoinflammatory processes. Complicated changes in blood condition were also detected against the background of diabetes mellitus: chronometric hypocoagulation on the intrinsic pathway of blood coagulation in association with chronometric hypercoagulation by the external thrombinogenesis mechanism and fibrinogenesis depression against the background of hypofibrinogenaemia...

Morbidity and mortality of cardiovascular disease (CVD) is exceedingly high worldwide. Depressive illness is a serious psychiatric illness that afflicts a significant portion of the world population. Epidemiological studies have confirmed the high co-morbidity between these two disease entities. The co-morbidity is bidirectional and the mechanisms responsible for it are complex and multifaceted. In addition to genetic, biological systems, psychosocial, and behavioral factors that are involved include the central and autonomic nervous systems, the neuroendocrine, immune, and the vascular and hematologic systems...

Chronic hepatitis C virus (HCV) infection is associated with fatigue and depression. Cognitive impairments are also reported in a smaller number of HCV-positive patients. Recent studies linked HCV to low-grade inflammation in brain. Here, we test the hypothesis that chronic HCV is associated with 3T-neuroimaging-derived grey matter volume (GMV) and functional connectivity alterations in a sample of chronic HCV (1b), without severe liver disease. Regional GMV and resting-state fMRI-derived eigenvector centrality (EC) were compared between 19 HCV-positive patients and 23 healthy controls (all females, 50-69 and 52-64 years, respectively), controlling for white matter hyperintensities and age...

The most common mood disorders are major depressive disorders and bipolar disorders. The pathophysiology of bipolar disorder is complex, multifactorial, and not fully understood. Creation of new hypotheses in the field gives impetus for studies and searching new biomarkers of the bipolar disorder. Conversely, new biomarkers facilitate not only diagnosis of a disorder and monitoring of biological effects of treatment, but also formulation of new hypotheses of the causes and pathophysiology of the bipolar disorder...

Elevated levels of circulating pro-inflammatory cytokines are associated with symptomology of several psychiatric disorders, notably major depressive disorder. Symptomology has been linked to inflammation/cytokine-dependent induction of the Kynurenine Pathway. Galectins, like pro-inflammatory cytokines, play a role in neuroinflammation and the pathogenesis of several neurological disorders but without a clearly defined mechanism of action. Their involvement in the Kynurenine Pathway has not been investigated...

Stress is associated with many diseases and dysfunctions, such as depression, cardiovascular alterations, immunological function disorder, inflammation, obesity, and insulin resistance. Stress-induced inflammation is associated with the genesis of insulin resistance. Stress activates hypothalamic pituitary adrenal axis, Renin Angiotensin System pathway, and sympatho-adrenal system, all of which are involved in the production of cytokines, causing the negative downregulation of insulin signaling either by phosphorylating serine residues of IRS or by inhibiting the activity of Akt leading to insulin resistance...

Exposure to painful procedures and/or stressors during the early neonatal period can reprogram the underlying neurocircuitry involved in nociception and neuropathic pain perception. The reprogramming of these systems can result in an enduring elevation in sensitivity towards mechanical and thermal stimuli. Recent evidence suggests that exposure to mild inflammatory mediators during the neonatal period can induce similar pain responses in both adolescent and adult rats. Therefore, we sought to profile changes in the expression of several genes across brain areas involved in the active modulation of nociception and neuropathic pain using a well-recognized model of neonatal inflammation...

The mechanisms by which inflammation affects the different emotional moods are only partially known. Previous works have pointed to stress hormones like glucocorticoids plus the vascular factor endothelin-1 as key factors evoking stressful states especially in relation to endothelial dysfunctions. With this work, it was our intention to establish the role of pro- and anti-inflammatory cytokine expression variations towards depression-like behaviors and consequently the development of neurodegeneration events caused by endothelial damages in the hamster (Mesocricetus auratus)...

The mechanisms and temporal sequence underlying the association between major depressive disorder (MDD) and cardio-metabolic diseases are still poorly understood. Recent research suggests subtyping depression to study the mechanisms underlying its association with biological correlates. Accordingly, our aims were to (1) assess the prospective associations of the atypical, melancholic and unspecified subtypes of MDD with changes of fasting glucose, high-density lipoprotein-cholesterol, triglycerides, systolic blood pressure and the incidence of the metabolic syndrome, (2) determine the potential mediating role of inflammatory marker or adipokine concentrations, eating behaviors and changes in waist circumference during follow-up...

Several pro-inflammatory cytokines have been implicated in depression and in antidepressant response. This exploratory analysis assessed: 1) the extent to which baseline cytokine levels predicted positive antidepressant response to ketamine; 2) whether ketamine responders experienced acute changes in cytokine levels not observed in non-responders; and 3) whether ketamine lowered levels of pro-inflammatory cytokines, analogous to the impact of other antidepressants. Data from double-blind, placebo-controlled studies of patients with major depressive disorder (MDD) or bipolar disorder (BD) who received a single infusion of sub-anesthetic dose ketamine were used (N = 80)...

Spinal cord injury (SCI) is a devastating event that results in significant physical disabilities for affected individuals. Apart from local injury within the spinal cord, SCI patients develop a variety of complications characterized by multiple organ dysfunction or failure. These disorders, such as neurogenic pain, depression, lung injury, cardiovascular disease, liver damage, kidney dysfunction, urinary tract infection, and increased susceptibility to pathogen infection, are common in injured patients, hinder functional recovery, and can even be life threatening...

Accumulating evidence has shown that chronic injection of d-galactose (d-gal) can mimic natural aging, with accompanying liver and brain injury. Oxidative stress and apoptosis play a vital role in the aging process. In this study, the antioxidant ability of polydatin (PD) was investigated using four established in vitro systems. An in vivo study was also conducted to investigate the possible protective effect of PD on d-gal-induced liver and brain damage. The results showed that PD had remarkable in vitro free radical scavenging activity on 2,2-diphenyl-1-picryl-hydrazyl (DPPH˙), 2,2'-azino-bis(3-ethylbenzo-thiazoline-6-sulfonic acid) (ABTS(+)˙) radical ions, and hydroxyl and superoxide anions...

This study was designed to investigate the antidepressant-like effect of umbelliferone (Umb) in mice exposed to unpredictable chronic mild stress and in lipopolysaccharide (LPS)-induced BV2 microglial cell and its potential mechanisms underlying this action was elaborated. In vivo, a series of behavioral assays including SPT, OFT, FST, and TST suggested that Umb (20 and 40 mg/kg) could improve effectively depression-like symptoms. The serum levels of inflammatory cytokines IL-6, IL-1β, and TNF-α presented marked decreases after the treatment of Umb...
