background and objectives: biological scaffold resources composed of extracellular matrix (ecm) have been shown to make easy the practical remodeling of various tissues in both animal and human studies. the goal of current study was to make sheet form of ecm from sheep’s urinary bladder. methods: ecm was extracted from sheep’s urinary bladder according to standard method. scanning electron mic...

We analyze the possibility of leptonic mixing matrix having a Wolfenstein form at Grand Unified Theory scale. The renormalization group evolution masses and angles from high scale to electroweak scale, in certain new physics scenarios, can significantly alter matrix. In past it was shown that such significant enhancement implies be same or similar structure quark one. thoroughly this hypothesis...
