    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
The main object of this study is to examine the effect of Klamin®, a nutraceutical containing phenylethylamine, phycocyanins, mycosporine-like aminoacids and aphanizomenon flos aquae-phytochrome on the learning and memory ability, the oxidative status and cerebral erythropoietin and its receptor EPO/EPOR system in prematurely senescent (PS) mice. A total of 28 PS mice, selected according to a prior T-maze test, and 26 non-prematurely senescent mice (NPS) mice were chosen. PS animals were divided into 3 groups and followed for 4 weeks: A) normal chow diet; B) added with Klamin® at 20 mg/kg/day (low dose); C) added with Klamin® at 100mg/kg/day (high dose). A further group of NPS mice given either normal food (group D) or high dose Klamin® (group E) was also considered. The behavioral procedures of spatial learning ability (Morris test) showed that PS mice had significantly longer learning time as compared to their NPS counterpart (p<0.01), but this effect was prevented especially in mice supplemented with high-dose Klamin® (p<0.05) which improved performances in NPS mice (p<0.05). High-dose Klamin® supplementation restored the depleted total thiol concentration in the brain observed in PS mice while normalizing their increased malonildialdehyde level (p<0.05). Moreover, the high-dosage only caused a significant upregulation of EPO/EPOR system both in PS and in NPS animals (p<0.05). Taken together, these data suggest that this specific alga Klamath extract has considerable antioxidant and adaptogenic properties, also through a stimulatory effect of cerebral EPO/EPO system PubMed
