    The first International ReGenera R&D International for Aging Intervention and VCC Preventive Medical Promotion Foundation has been a flashy success.

    It has been held in Beijing last June 8, having as topics Gut Microbiota and Health. The keynote speaker was prof. Marotta and the meeting features the most authoritative Asian specialists in the field.

    The conference room was fully packed and, most important, about 10.000 physicians and health professionals registered for a live attendance at distance.

    The event as covered by the most reputed national TV channels and in the next days a series of interviews followed up.

    The organizer, VCC Preventive Medical Promotion Foundation, given this success, is planning further similar top scientific gatherings this year in other locations.

    There was a general consensus on the importance to deepen our knowledge in this area as well ass starting providing practical steps forwards an evaluation and phenotypic monitoring of gut microbiota, while envisaging designer pro-prebiotics interventions.

Abstract

Brain tissue is particularly susceptible to oxidative stress (OS). Increased production of reactive oxygen species (ROS), reduced antioxidant systems, and decreased efficiency in repairing mechanisms have been linked to Alzheimer’s disease (AD). Postmortem studies in AD patients’ brains have shown oxidative damage markers (i.e., lipid peroxidation, protein oxidative damage, and glycoxidation). Fermented papaya (FPP, a product of Carica papaya Linn fermentation with yeast) is a nutraceutical supplement with favorable effects on immunological, hematological, inflammatory, and OS parameters in chronic/degenerative diseases. We studied 40 patients (age 78.2 ± 1.1 years), 28 AD patients, and 12 controls. Urinary 8-OHdG was measured to assess OS. Twenty AD patients were supplemented with FPP (Immunage, 4.5 grams/day) for 6 months, while controls did not receive any treatment. At baseline, 8-OHdG was significantly higher in patients with AD versus controls (13.7 ± 1.61 ng/mL versus 1.6 ± 0.12 ng/mL, P < 0.01). In AD patients FPP significantly decreased 8-OHdG (14.1 ± 1.7 ng/mL to 8.45 ± 1.1 ng/mL, P < 0.01), with no significant changes in controls. AD is associated with increased OS, and FPP may be helpful to counteract excessive ROS in AD patients.
