A comparison of human brain dissection by drill versus saw on nucleic acid quality

This study examined the effect of two dissection techniques on the quality of human brain specimens. Frozen cerebellar samples were obtained from postmortem brains of 10 subjects free from neurological and psychiatric disease. These tissues were tested for RNA and DNA concentration and quality after being dissected with either an electric dental drill or a small handsaw. RNA and DNA were extracted separately from each sample, and the concentrations and quality of each were measured. We found that dissection technique does not significantly affect RNA or DNA quality/yield. RNA and DNA yields, as well as RNA integrity showed no significant differences between the two dissection techniques. Therefore, these results support the use of a high-speed hand-held electric dental drill as an efficient and anatomically precise means of human brain dissection without compromising tissue quality.

Beyond Study Abroad: A Human Rights Delegation to Teach Policy Advocacy

Advancement of human rights is a core competency in the social work curriculum. Presented is a model to teach policy practice from a human rights perspective based on a violence-against-women delegation visit to Guatemala. Postdelegation policy advocacy responses included White House and State Department briefings on the problems, including femicide. Case examples of witnessed testimony about human rights violations, including rape, femicide, and human trafficking, reflect the unique and dynamic nature of social work practice in a global context. We link Council on Social Work Education core competencies in policy practice and human rights to experiential learning strategies used by the delegation and derive lessons learned to advance human rights education for the profession. © 2013 Council on Social Work Education
