To investigate the active factors and the intervention effect of ω-3 polyunsaturated fatty acids (PUFAs) during intestinal ischemia-reperfusion (I/R) injury, which causes the inflammation of monocytes-macrophages cultured in lymph fluid and stimulated with ω-3 PUFAs. ⋯ The factors induced in lymph during intestinal I/R injury can cause inflammation in vitro. These data provide in vitro evidence that ω-3 PUFAs provide a protective effect by reducing the inflammatory response caused by intestinal I/R lymph. Moreover, the synergism of EPA and DHA had the greatest effect, which is possibly mediated through Toll-like receptor 4 and nuclear factor-κB p65.

Three separate studies were performed with the aim to 1) determine the effect of a single sodium pyruvate intake on the blood acid-base status in males and females; 2) compare the effect of sodium and calcium pyruvate salts and establish their role in the lipolysis rate; and 3) quantify the effect of single pyruvate intake on the resting energy metabolism. ⋯ Pyruvate intake induced mild alkalization in a sex-dependent fashion. Moreover, it accelerated carbohydrate metabolism and delayed the rate of glycerol appearance in the blood, but had no effect on the resting energy expenditure. Furthermore, sodium salt seems to have had a greater effect on the blood buffering level than calcium salt.

The aim of this study was to estimate the weighted mean effect of vitamin D supplementation in reducing depressive symptoms among individuals aged ≥18 y diagnosed with depression or depressive symptoms. ⋯ Future RCTs examining the effect of vitamin D supplementation among individuals who are both depressed and vitamin D deficient are needed.

Randomized Controlled Trial
Effect of non-soy legume consumption on inflammation and serum adiponectin levels among first-degree relatives of patients with diabetes: a randomized, crossover study.
First-degree relatives of patients with diabetes are at more risk for endothelial dysfunction and inflammation. The aim of the present study was to determine the effects of a non-soy legume-enriched diet on inflammatory biomarkers and serum adiponectin levels among first-degree relatives of these patients. ⋯ The results of this study showed that a legume-enriched diet significantly reduced the hs-CRP concentrations in first-degree relatives of patients with diabetes after 6 wk of intervention compared with a habitual diet.

Dietary antioxidant supplementation has been popular in Western countries. Various supplements have been developed in recent years, and research has been gathered from both animal and clinical research trials. In this review, the therapeutic value of oral administration of a combination of melon superoxide dismutase (SOD) and a vegetable polymer (gliadin) is evaluated. ⋯ These conclusions are dependent on the condition or pathology under consideration. In general, the authors, who analyzed SOD-gliadin supplementation, support the use of SOD-gliadin supplementation as a complementary treatment rather than a therapeutic treatment. To further clarify the importance of dietary SOD-gliadin administration, additional large-scale clinical trials are recommended.
