Randomized Controlled Trial Clinical Trial
Lutein, but not alpha-tocopherol, supplementation improves visual function in patients with age-related cataracts: a 2-y double-blind, placebo-controlled pilot study.
We investigated the effect of long-term antioxidant supplementation (lutein and alpha-tocopherol) on serum levels and visual performance in patients with cataracts. ⋯ Visual function in patients with age-related cataracts who received the lutein supplements improved, suggesting that a higher intake of lutein, through lutein-rich fruit and vegetables or supplements, may have beneficial effects on the visual performance of people with age-related cataracts.

We assessed the mechanisms of ribonucleotide action on type 1 T-helper cell (Th1) responses against ovalbumin (OVA) in Th2-biased BALB/cJ mice. ⋯ Dietary ribonucleotides may attenuate skewed Th2 responses by augmenting clonal expansion of OVA-specific Th1 cells, suppressing expansion of OVA-specific Th2 cells in Th2-biased BLAB/cJ mice, and not affecting antigen non-specific cell surface markers.
