High-fibre diet cuts heart disease risk

The study from Northwestern University Feinberg School of Medicine found adults between 20 and 59 years old with the highest fibre intake had a significantly lower estimated lifetime risk for cardiovascular disease compared to those with the lowest fibre intake.

Hongyan Ning, lead author, examined data from the National Health and Nutrition Examination Survey, a nationally representative sample of about 11,000 adults.
Ning considered diet, blood pressure, total cholesterol, smoking status and history of diabetes in survey participants and then used a formula to predict lifetime risk for cardiovascular disease. “The results are pretty amazing. Younger (20 to 39 years) and middle-aged (40 to 59 years) adults with the highest fibre intake, compared to those with the lowest fibre intake, showed a statistically significant lower lifetime risk for cardiovascular disease.”

TM improves math and English scores

A new study has shown that the Transcendental meditation (TM) technique may be an effective approach to improve math and English academic achievement in low-performing students.

The study was conducted at a California public middle school with 189 students who were below proficiency level in English and math. Change in academic achievement was evaluated using the California Standards Tests (CST).

Students who practiced TM showed significant increases in math and English scale scores and performance level scores over a one-year period. Forty-one per cent of the meditating students showed a gain of at least one performance level in math compared to 15 per cent of the non-meditating controls.

Among the students with the lowest levels of academic performance, ‘below basic’ and ‘far below basic’, the meditating students showed a significant improvement in overall academic achievement compared to controls, which showed a slight gain.

New discovery holds promise for liver cancer treatment

Researchers have discovered a novel mechanism in gene regulation that contributes to the development of a form of liver cancer called hepatocellular carcinoma (HCC).
Devanand Sarkar, Virginia Commonwealth University, has identified a promising new target for therapeutic intervention.

He describes for the first time how RNA-induced silencing complex (RISC) contributes to the development of liver cancer. RISC is an important factor in post-transcriptional gene regulation, which occurs between transcription (where DNA is converted to RNA) and translation (where RNA is converted to protein). Sarkar identified the proteins AEG-1 and SND1 as factors that increase RISC activity and lead to the development of liver cancer.
