OBJECTIVE: Temperament has associations with later physical health outcomes, yet there is a dearth of research exploring the connection between temperament and mechanisms that have known associations with these health outcomes. Recent research has delineated a connection between personality and inflammation during adulthood, but this association has not yet been studied in adolescent samples. DESIGN: We investigated whether stable adolescent temperament (averaged over two years), specifically effortful control and negative emotionality, provided a more robust prediction of inflammation as measured by salivary C-reactive protein (sCRP), than depressive symptoms...

Depressive disorder is a kind of affective disturbance disease. Emerging evidence has suggested that inflammation may contribute to the pathologic process of depressive disorder. Senegenin (SEN), a major bioactive constituent in Polygala tenuifolia Willd, has much bioactivity including anti-inflammatory and neuroprotection effects. However, the mechanism of its anti-depressant effect in mice remains unknown. This study aimed to explore the anti-depressant effects of SEN on behavioral changes and inflammatory responses in mice induced by chronic un-predictable mild stress (CUMS)...

OBJECTIVE: Although mechanical ventilation is frequently a life-saving therapy, its use can result in unwanted side effects. It has been well documented that the choice of sedating agent may influence the duration of mechanical ventilation. Melatonin is a sedative and analgesic agent without any respiratory depressant effect which makes it an attractive adjuvant for sedation in the intubated patients. The aim of this study is to evaluate the effect of melatonin on the duration of mechanical ventilation in patients with hemorrhagic stroke...

Ginseng effectively regulates the immune response and the hormonal changes due to stress, thus maintaining homeostasis. In addition to suppressing the occurrence of psychological diseases such as anxiety and depression, ginseng also prevents stress-associated physiological diseases. Recent findings have revealed that ginseng is involved in adjusting the hypothalamic-pituitary-adrenal axis and controlling hormones, thus producing beneficial effects on the heart and brain, and in cases of bone diseases, as well as alleviating erectile dysfunction...

Mood disorders such as depression are among the most prevalent psychiatric disorders in the United States, but they are inadequately treated in a substantial proportion of patients. Accordingly, neuropsychiatric research has pivoted from investigation of monoaminergic mechanisms to exploration of novel mediators, including the role of inflammatory processes. Subsets of mood disorder patients exhibit immune-related abnormalities, including elevated levels of proinflammatory cytokines, monocytes, and neutrophils in the peripheral circulation; dysregulation of neuroglia and blood-brain barrier function; and disruption of gut microbiota...

BACKGROUND: Major depressive disorder (MDD) affects many people in the world. However, around 40% of patients do not respond to any pharmacological drugs. An alternative is to use a combination of different pharmacological groups or the combination of a classical antidepressant with a substance that can potentiate its effect. Thus, this study aimed to investigate the synergistic interactions between different antidepressants, including fluoxetine, quetiapine and lamotrigine in combination with ketamine, a N-methyl-d-aspartate (NMDA) receptor antagonist...

Patients suffering from chronic neuropathic pain are at high risk of co-morbid depression, which burdens healthcare. Trans-astaxanthin has been shown in our previous studies to exert antidepressant-like effect. This work aimed to investigate the effects of trans-astaxanthin on pain-related depressive-like behaviors in mice and explored the mechanism(s). Chronic constriction injury (CCI) model was used in this research. Chronic pain was evaluated by thermal hyperalgesia in Hargreaves test and mechanical allodynia in von Frey test, depressive-like behaviors were evaluated by immobility time in forced swim test and tail suspension test...

Random pattern skin flap transplantation is frequently applied in plastic and reconstructive surgery, but the distal part of skin flaps often suffers necrosis due to ischemia. Astragaloside IV (AS-IV), a natural saponin purified from Astragalus membranaceus, may have beneficial functions for flap survival. In this study, rats were divided into a control group and an AS-IV treatment group, and underwent surgery using a modified "McFarlane flap" model. After intragastric administration of vehicle control or AS-IV for their respective groups, flap survival area and water content were measured 7 days after surgery...

Depression and anxiety, the most important psychological disorders in cancer patients, have now been considered as psychoneuroimmunological disorders, in which peripheral immune activation, through the release of proinflammatory cytokines, is implicated in the variety of behavioral, neuroendocrine and neurochemical alterations associated with these disorders. Along with the tumor itself, cancer treatment can also contribute to exacerbate the production of proinflammatory cytokines. This study aimed to investigate whether proinflammatory cytokine levels are related to depression and anxiety in CRC patients in different stages of the antitumor therapy We evaluated 60 patients in three stages of antitumor therapy (Pre-chemotherapy, Under-chemotherapy and Post-chemotherapy, n=20 in each group) and 20 healthy volunteers by the Hospital Anxiety and Depression Scale (HADS)...

Psychosocial factors are an important contributor to the aetiology of unipolar depression. This paper reviews the evidence for the contribution of different psychosocial factors, and provides an overview of the proposed neurobiological mechanisms underlying the link between psychosocial factors and depression. Implicated psychosocial factors fall into three interrelated groups: life events, socioeconomic status, and social support. The life events most strongly linked with depression are bereavement, disability or medical illness, and childhood maltreatment...

Depression has been associated with a low-grade chronic inflammatory state, suggesting a potential therapeutic role for anti-inflammatory agents. Fisetin is a naturally occurring flavonoid in strawberries that has anti-inflammatory activities, but whether fisetin has antidepressant effects is unknown. In this study, we exposed mice to spatial restraint for 2 weeks with or without treatment with fisetin. Immobility time in the forced swimming and tail suspension test after this restraint increased in the untreated group, but this increase did not occur in the fisetin group...

Activation of the mu-opioid receptor provides the gold standard for pain relief, but a majority of opioids used clinically have adverse effects that have contributed to an epidemic of overdose deaths. We recently characterized mu-opioid receptor selective endomorphin (EM) analogs that provide potent antinociception with reduction or absence of a number of side effects of traditionally prescribed opioids including abuse liability, respiratory depression, motor impairment, tolerance, and inflammation [91]. The current study explores the effectiveness of these EM analogs relative to morphine in four major pain models by both intrathecal and intravenous administration in male, Sprague-Dawley rats and male CD-1 mice...

Vibeke Strand, Jasvinder A Singh
Axial spondyloarthritis (AxSpA) is an inflammatory spondyloarthritis (SpA) that has significant impact on a patient's life. Symptoms, including fatigue, sleep problems, depression, and sexual dysfunction, can profoundly impact health-related quality of life (HRQoL) and limit work, leisure, and daily activities. Available therapies effectively manage pain and inflammation in early-stage disease, but patients often continue to experience impaired HRQoL. Thus, there remains a need for new therapies with novel mechanisms that can stop disease progression, potentially reverse damage caused by AxSpA and improve HRQoL in patients with AxSpA...

The hypothalamus is the brain region responsible for the maintenance of energetic homeostasis. The regulation of this process arises from the ability of the hypothalamus to orchestrate complex physiological responses such as food intake and energy expenditure, circadian rhythm, stress response, and fertility. Metabolic alterations such as obesity can compromise these hypothalamic regulatory functions. Alterations in circadian rhythm, stress response, and fertility further contribute to aggravate the metabolic dysfunction of obesity and contribute to the development of chronic disorders such as depression and infertility...

In neuropathic pain (NP), the atrophy of hippocampus contributes to the comorbidity between pain, depression and the cognitive deficits. However, the exact mechanism underling the comorbidity, the effective control of the degenerations in hippocampus and the remission of the accompanied depressive symptoms are still lacking. Wu-Tou decoction (WTD) has been prescribed for inflammatory pain for thousands of years. In this study, we manifested the effects of WTD on the pain, depression and anxiety co-curative symptoms of NP...

BACKGROUND: Recent evidence has suggested that peripheral inflammatory responses induced by lipopolysaccharides (LPS) play an important role in neuropsychiatric dysfunction in rodents. Interleukin-1β (IL-1β), a pro-inflammatory cytokine, has been proposed to be a key mediator in a variety of behavioral dysfunction induced by LPS in mice. Thus, inhibition of IL-1β may have a therapeutic benefit in the treatment of neuropsychiatric disorders. However, the precise underlying mechanism of knock-down of IL-1β in repairing behavioral changes by LPS remains unclear...

Periodontal disease is a frequent chronic inflammatory pathology that implies the destruction of the tissues supporting the teeth, which represents a high sanitary cost. It usually appears associated with other systemic conditions such as diabetes, metabolic syndrome, depression and Alzheimer disease among others. The presence of melatonin and its receptors in the oral cavity supports the hypothesis that this hormone could play a role in homeostasis of periodontal tissues. In the present review we will discuss the potential role of melatonin, a circadian synchronizing hormone, with proved antiinflammatory and antioxidant profile, in the pathogenesis and treatment of periodontitis...
