Counteracting HPV Cervical and Anal Infection through Dietary Supplementation of EGCG, Folic Acid, Vitamin B12 and Hyaluronic Acid: Clinical Case Reports.

Human papilloma virus (HPV) infection and the management of its persistence is still a great medical challenge. Recently, scientific evidence has supported the potential therapeutic effects of four combined natural molecules-epigallocatechin gallate (EGCG), folic acid, vitamin B12 and hyaluronic acid (HA)-in counteracting HPV DNA positivity and related cytological lesions. : Each patient of these five clinical cases had persistent HPV positivity in the anogenital site and assumed a dietary supplement based on a combination of 200 mg of EGCG, 50 mg of HA, 1 mg of vitamin B12 and 400 mcg of folic acid (Pervistop, Farmares s.

Ionizing Radiation-Induced Extracellular Vesicle Release Promotes AKT-Associated Survival Response in SH-SY5Y Neuroblastoma Cells.

Radiation therapy is one of the most effective methods of tumor eradication; however, in some forms of neuroblastoma, radiation can increase the risk of secondary neoplasms, due to the ability of irradiated cells to transmit pro-survival signals to non-irradiated cells through vesicle secretion. The aims of this study were to characterize the vesicles released by the human neuroblastoma cell line SH-SY5Y following X-ray radiations and their ability to increase invasiveness in non-irradiated SH-SY5Y cells. We first purified the extracellular vesicles released by the SH-SY5Y cells following X-rays, and then determined their total amount, dimensions, membrane protein composition, and cellular uptake.
