Objective: The protective effects of fish oil (FO) on cisplatin (CP)-induced central and peripheral neurotoxicity were investigated in rats.
Methods: Rats (n = 28) were divided equally into four groups, the first group was kept as a control. In the second and third groups, CP and FO were given at doses of 7 mg/kg and 1 softgel/rat/day, respectively. In the fourth group, CP and FO were given together at the same doses.
Results: Although CP caused significant oxidative damage, via induction of lipid peroxidation and reduction in the antioxidant defense system potency, FO treatment largely reversed these effects. CP also resulted in histopathological damage, such as apoptosis, and electromyographical changes in the sciatic nerve. FO treatment partially prevented the histopathological and electromyographical effects of CP.
Discussion: CP has severe central and peripheral neurotoxic effects in rats and these effects were largely prevented by FO treatment. Thus, it appears that co-administration of FO with CP may be a useful approach to attenuate the negative effects of CP on the nervous system.

Osteoarthritis (OA) is characterized by articular cartilage degeneration, leading to pain and loss of joint function. Recent studies have demonstrated that omega-3 (ω3) polyunsaturated fatty acid (PUFA) supplementation can decrease injury-induced OA progression in mice fed a high-fat diet. Furthermore, PUFAs have been shown to influence the mechanical properties of chondrocyte membranes, suggesting that alterations in mechanosensitive ion channel signaling could contribute to the mechanism by which ω3 PUFAs decreased OA pathogenesis.

Background: The Mediterranean diet has been associated with decreased brain atrophy (Staubo et al. 2016,Alz&Dem), but the MIND (Mediterranean-Dietary Approaches to Stop Hypertension (DASH) Intervention for Neurodegenerative Delay) diet, designed for dementia prevention (Morris et al. 2015, Alz&Dem), remains underexplored for its impact on brain atrophy.

Background: Alzheimer's disease (AD) is the most common etiology of dementia. As the progression of the disease may be slowed down by disease-modifying therapies, but not stopped, research identifying further therapeutic approaches is necessary. Due to the multifactorial etiology of AD, targeting modifiable risk factors for dementia, including diet, is a starting point for preventive interventions.

Background: There is an urgent need to identify novel, accessible and affordable strategies to prevent cognitive decline and progression in the Alzheimer disease and related dementias (ADRD) continuum. Vitamin D3 and marine omega-3 fatty acids (omega-3s) supplements show promise for cognitive protection, with potential variations in their effects by sex or race. However, to date, no randomized clinical trials (RCTs) have tested their impact on emerging plasma-based biomarkers with potential utility to predict ADRD pathogenesis.

Here, we explored whether dietary factors might attenuate the association between magnetic resonance imaging (MRI)-derived vascular biomarkers and cognition.
