Abstract
Induced pluripotent stem cells (iPSCs) are obtained by genetically reprogramming adult somatic cells via the overexpression of specific pluripotent genes. The resulting cells possess the same differentiation properties as blastocyst-stage embryonic stem cells (ESCs) and can be used to produce new individuals by embryonic complementation, nuclear transfer cloning, or in vitro fertilization after differentiation into male or female gametes. Therefore, iPSCs are highly valuable for preserving biodiversity and, together with somatic cells, can enlarge the pool of reproductive samples for cryobanking. In this study, we subjected rabbit iPSCs (rbiPSCs) and rabbit ear tissues to several cryopreservation conditions with the aim of defining safe and non-toxic slow-freezing protocols. We compared a commercial synthetic medium (STEM ALPHA.CRYO3) with a biological medium based on fetal bovine serum (FBS) together with low (0-5%) and high (10%) concentrations of dimethyl sulfoxide (DMSO). Our data demonstrated the efficacy of a CRYO3-based medium containing 4% DMSO for the cryopreservation of skin tissues and rbiPSCs. Specifically, this medium provided similar or even better biological results than the commonly used freezing medium composed of FBS and 10% DMSO. The results of this study therefore represent an encouraging first step towards the use of iPSCs for species preservation.

Abstract
This study was made to determine contact with drugs among first-grade students from public and private schools in the Riberao Preto community. The various social classes were considered. We decided to use the concept of social status for out empiric research, which defines it as a group of persons who have a certain number of characteristics in common which can be measured, that is, common status, and which may be defined by different criteria. Schools were classified according to their pupils, and after this initial classification, they were divided into 4 groups. A school was selected by lots from each group. A questionnaire with open and closed questions was used as instrument for data collection. According to the collected data, it was concluded that all pupils, independently from their social and economic level, had a superficial knowledge on drugs: 48.2% of those surveyed said they knew people in their neighbourhood who used drugs; 8.8% referred that they had been offered drugs. Drugs offered to them included; cocaine, marijuana, hashish, cigarettes and toxic pencils. The other 63% referred that nobody had given them any advice regarding drugs.
