Based oil the high-efficiency vitrification Cryotop method, a practical vitrification procedure for murine, bovine and human ovarian tissue was developed. A Cryotissue method was designed for cryopreservation of ovarian tissue. and vitrification experiments were performed in a bovine Selleck MAPK inhibitor animal model

with ovarian size and structure similar 10 the human. There was no difference in oocyte viability (>89%) between fresh and vitrified ovarian cortical tissue in either bovine or human samples. Ovarian tissue was successfully autotransplanted to six cattle. Autotransplantation of vitrified-warmed tissue back to the cattle resulted in no loss of oocyte viability. In addition. human ovarian tissue front cancer patients, and from ovary transplant donors was also vitrified by the Cryotissue method. After warming, high oocyte survival

in human tissue (similar to bovine tissue) was obtained. These results indicate that all ultra-rapid cooling vitrification method has the potential for clinical use in human ovarian tissue cryopreservation.”
“Despite an archive of over 73,000 research papers published in the last two decades on the subject of Alzheimer’s disease (AD), little clinical progress has been made see more relative to how people get sporadic AD and what can be done to help them avoid it. This review spotlights

strategic steps that could be a turning point in the dramatic lowering of Alzheimer prevalence. The main strategy includes application of four pillars of prevention: 1) early identification of AD vascular risk factors; 2) early detection of AD vascular risk factors; 3) early intervention ALK assay of AD vascular risk factors based on evidence-based medical decisions; 4) patient follow-up to assess and modify interventions as needed. Tandem to these four pillars of prevention, a proactive lifestyle consisting of a healthy diet coupled to physical and mental activity should be applied as part of any therapeutic intervention. We are persuaded by mounting and compelling evidence that AD is a multifactorial disorder kindled by vascular risk factors that generate chronic brain hypoperfusion (CBH) during advanced aging. A pathobiological cascade of biochemical events in the presence of CBH that leads to oxidative stress and neurodegeneration appears to involve multiple biofactors including micronutrients, trace metals, lipids, and pro-oxidants, as reviewed in this special issue of BioFactors. Modulation of these biofactors may help prevent or control incipient AD. (c) 2012 International Union of Biochemistry and Molecular Biology, Inc.”
