This article is from Journal of Visualized Experiments : JoVE . Abstract The preparation of single-cell suspensions from tissues is an important prerequisite for many experiments in cellular research. The process of dissociating whole organs requires specific parameters in order to obtain a high number of viable cells in a reproducible manner. The gentleMACS Dissociator optimizes this task with a simple, practical protocol. The instrument contains pre-programmed settings that are optimized for...

This article is from Journal of Visualized Experiments : JoVE . Abstract Within the nervous system, hundreds of neuronal and glial cell types have been described. Each specific cell type in the brain or spinal cord has a repertoire of cell surface molecules, or molecular determinants, through which it can be identified and characterized. Currently, robust cell identification and separation technologies require single-cell preparations to be generated while simultaneously limiting cell death and...

This article is from International Journal of Oral Science , volume 1 . Abstract Dentin matrix metalloproteinases (MMPs) are a family of host-derived proteolytic enzymes trapped within mineralized dentin matrix, which have the ability to hydrolyze the organic matrix of demineralized dentin. After bonding with resins to dentin there are usually some exposed collagen fibrils at the bottom of the hybrid layer owing to imperfect resin impregnation of the demineralized dentin matrix. Exposed...

Special attention was paid to how the negative researchers argue about the “osteocytic...

This article is from Brazilian Journal of Microbiology , volume 40 . Abstract A clear understanding of the pharmacodynamic properties of antifungal agents is important for the adequate treatment of fungal infections like candidiasis. For certain antifungal agents, the determination of Minimal Fungicidal Concentration (MFC) and time kill curve could be clinically more relevant than the determination of the Minimal Inhibitory Concentration (MIC). In this study, MIC and MFC to fluconazole,...

Abstract Compulsive drug-taking behavior develops in vulnerable individuals who ingest substances that activate the reward system. This intense activation produces learned associations to cues that predict drug availability. With repetition the reward system becomes reflexively activated by cues alone, leading to a drive toward drug-taking. The central nervous system changes underlying this conditioned behavior are just...
