Zhe Shi, Huixia Ren, Zhijian Huang, Yu Peng, Baixuan He, Xiaoli Yao, Ti-Fei Yuan, Huanxing Su
Depression is associated with somatic immune changes, and neuroinflammation is now recognized as hallmark for depressive disorders. N-3 (or omega-3) polyunsaturated fatty acids (PUFAs) are well known to suppress neuroinflammation, reduce oxidative stress, and protect neuron from injury. We pretreated animals with fish oil and induced acute depression-like behaviors with systemic lipopolysaccharide (LPS) injection. The levels of cytokines and stress hormones were determined from plasma and different brain areas...

Over the past three decades a body of translational evidence has implicated dietary deficiency in long-chain omega-3 (LCn-3) fatty acids, including eicosapenaenoic acid (EPA) and docosahexaenoic acid (DHA), in the pathophysiology and etiology of major depressive disorder (MDD). Cross-national and cross-sectional data suggest that greater habitual intake of preformed EPA+DHA is associated with reduced risk for developing depressive symptoms and syndromal MDD. Erythrocyte EPA and DHA composition is highly correlated with habitual fish or fish oil intake, and case-control studies have consistently observed lower erythrocyte EPA and/or DHA levels in patients with MDD...

Nutrition is one of the most important modifiable determinants for and consequences of both mental and physical heath. Depression has become an increasingly important public health issue. We tested whether dietary patterns derived from food group intake are associated with depression in U.S. adults in a cross-sectional study with national population. This study included 4180 men and 4196 women aged 20-79 years in the 2007-2010 National Health and Nutrition Examination Surveys (NHANES), with complete data of one 24-h dietary recall, sociodemographics, lifestyles, and Patient Health Questionnaires (PHQ-9) for screening depression...

BACKGROUND: Long-chain n-3 and n-6 polyunsaturated fatty acids (LC n-3/n-6 PUFA) play important roles in emotional regulation. We previously reported an association between fish consumption, which is major source of LC n-3 PUFA, and resilience to depression, where resilience is the ability to cope with stress in the face of adversity. Although the traditional Japanese dietary pattern of high fish consumption is associated with low depressive symptoms, the current Japanese diet pattern has become westernized...

Significant evidence supports the effectiveness and safety of several complementary or integrative treatment approaches to common primary care problems. Acupuncture is effective in the management of chronic low back pain. Mind-body interventions such as cognitive behavior therapy, yoga, tai chi, qi gong, and music therapy may be helpful for treating insomnia. Exercise can reduce anxiety symptoms. Herbal preparations and nutritional supplements can be useful as first-line therapy for certain conditions, such as fish oil for hypertriglyceridemia, St...

Human-induced perturbations such as crude-oil pollution can pose serious threats to aquatic ecosystems. To understand these threats fully it is important to establish both the immediate and evolutionary effects of pollutants on behaviour and cognition. Addressing such questions requires comparative and experimental study of populations that have evolved under different levels of pollution. Here, we compared the exploratory, activity and social behaviour of four populations of Trinidadian guppies (Poecilia reticulata) raised in common garden conditions for up to three generations...

Nutrigenomic studies of mammary lipogenesis in ruminants often rely on the use of mammary tissue (MT) collected either by biopsy or at slaughter. However, isolating RNA from milk would be a useful and cost-effective technique that may avoid distress to the animal and facilitate the collection of samples in time series experiments. This assay was therefore conducted to test the hypothesis that RNA extracted from milk somatic cells (MSC) in dairy sheep would be a feasible alternative to the performance of MT biopsies for nutrigenomic analyses...

Several studies in dairy cows have shown a relationship between milk fat depression (MFD) and alterations caused in lipogenic gene expression by dietary nutrients. However, information on small ruminants is not only scarce but also inconsistent. Therefore, this experiment was conducted in dairy ewes to study the effect of a diet known to induce MFD on milk fatty acid (FA) composition and mRNA abundance of key candidate genes involved in mammary lipogenesis. Twelve lactating Assaf ewes (on average 63d in milk) were randomly assigned to 2 treatments consisting of a total mixed ration based on alfalfa hay and concentrates (50:50), supplemented with 0 (control) or 17g of fish oil/kg of diet dry matter (FO)...

INTRODUCTION: The influence of n-3 long-chain polyunsaturated fatty acids (LCPUFA) supplementation on brain functioning is debated. Some studies have found positive effects on cognition in children with learning difficulties, elderly people with cognitive impairment and depression scores in depressed individuals. Other studies have found null or negative effects. Observational studies in adolescents have found positive associations between fish consumption (containing n-3 LCPUFAs) and academic achievement...

In Nigeria, communal conflicts arise due to misunderstanding from ownership of land for farming, oil deposits, solid minerals or water for fishing activities. It may also arise in defence of community pride and properties or even in defence of the people involved in the conflict. The General Health Questionnaire (GHQ-12), The Short Screening Scale for Post traumatic stress disorder, The Generalized Anxiety Disorder Scale (GAD-7) and the Beck Depression Inventory (BDI-2) were used to assess psychosocial impacts of communal conflicts among 560 secondary school youths from two communities in south east Nigeria...

BACKGROUND: Little is known about the effects of human fetal exposure when a new drug is authorized unless it was specifically developed for use in pregnancy. Since many factors may contribute to adverse fetal effects, having comprehensive information about in utero exposures will enhance our ability to make correct determinations about causality. OBJECTIVE: The objective of the study was to assess the extent to which women, recruited without the intervention of health care professionals (HCPs), will provide information, suitable for research purposes, via the Internet or by phone on some potential risk factors in pregnancy...

Doxorubicin (DOX) is a chemotherapeutic agent widely used in human malignancies. Its long-term use can cause neurobiological side-effects associated with depression. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs), the essential fatty acids found in fish oil, possess neuroprotecitve and antidepressant activities. Thus, the aim of this study was to explore the potential protective effects of ω-3 PUFAs against DOX-induced behavioral changes and neurotoxicity. ω-3 PUFAs were given daily by gavage (1.5 g/kg) over three weeks starting seven days before DOX administration (2...

AIMS: Fluoxetine (FLX) is an antidepressant worldwide prescribed throughout life stages, including pregnancy and breastfeeding. Out of pregnancy, the combination of FLX with fish oil (FO) and folic acid (FA) is carried to enhance the therapeutic activity and reduce the side effects of the antidepressant. During pregnancy, FO and FA have been used to promote fetal development, and reduce, in mother, the risk of gestational and post-pregnancy depression. To evaluate if maternal exposure during pregnancy and lactation to FLX associated with FO or FA would prevent the antidepressant side effects in aorta reactivity and nitric oxide metabolites (NOx) plasmatic levels...

Fish oil is composed of various fatty acids among which omega-3 fatty acids are considered as most beneficial. The effects of fish oil on the activity of a topical anticancer drug, imiquimod, and the immunomodulatory activity of omega-3 fatty acids was investigated in human basal and squamous cell carcinoma cell lines. Imiquimod-fish oil mixture exhibited higher carcinoma cell growth inhibition and immunomodulatory activity than imiquimod alone, especially against squamous cell carcinoma cells. Omega-3 fatty acids exhibited growth inhibition of both basal cell and squamous cell carcinoma cell lines and modulated the immune response...

A body of translational evidence has implicated dietary deficiency in long-chain omega-3 (LCn-3) fatty acids, including eicosapenaenoic acid (EPA) and docosahexaenoic acid (DHA), in the pathophysiology and potentially etiology of different psychiatric disorders. Case-control studies have consistently observed low erythrocyte (red blood cell) EPA and/or DHA levels in patients with major depressive disorder, bipolar disorder, schizophrenia, and attention deficit hyperactivity disorder. Low erythrocyte EPA + DHA biostatus can be treated with fish oil-based formulations containing preformed EPA + DHA, and extant evidence suggests that fish oil supplementation is safe and well-tolerated and may have therapeutic benefits...

White matter abnormalities are implicated in major depressive disorder (MDD). As omega-3 polyunsaturated fatty acids (PUFAs) are low in MDD and affect myelination, we hypothesized that PUFA supplementation may alleviate depression through improving white matter integrity. Acutely depressed MDD patients (n = 16) and healthy volunteers (HV, n = 12) had 25-direction diffusion tensor imaging before and after 6 weeks of fish oil supplementation. Plasma phospholipid omega-3 PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and omega-6 PUFA arachidonic acid (AA) levels were determined before and after supplementation using high-throughput extraction and gas chromatography and expressed as a percentage of total phospholipids (PUFA%)...
