By co-expressing these two proteins in C. elegans, they discovered that the healthy protein co-aggregated in a ...Lutein supplements may improve vision

The subjects took lutein supplements with breakfast every day for six months, 40 mg/day ......years, tracked cognitive decline in women who were asked to report estrogen use on a questionnaire given during each visit. Nearly all of the women gave blood samples containing the DNA necessary for ApoE genotyping. At each testing point, results were adjusted for factors that vary between estrogen use......Prior to dietary intervention, the volunteers were asked to follow a fat-modified diet (30% of energy from fat) for two weeks. Thereafter, they were assigned either to a control group or to one of the three dietary intervention groups over a 12-week period: 600 mg of folic acid in tablet form each day; 60...UCSF researchers find evidence of faulty DNA repair in some infertile men
