‘The Judiciary and Political Change in Africa: Developing Transitional Jurisprudence in Nigeria’

At a time of increased evaluations of law, human rights, and the rise of judicial power all over the globe, the work of most African judiciaries and the principles of the jurisprudence they espouse in promoting social justice remain an unlikely focus of comparative legal scholarship. This ought not to be so in view of the considerable activities of the courts on the continent in the dawn of the third wave of democratization. This article explores the work of the Nigerian Supreme Court in the political transition to democracy since 1999. Utilizing insights from the work of Ruti Teitel, it attempts to outline some of the major constitutional and extraconstitutional principles adopted by the Court in mediating intergovernmental contestations in the turbulent transition away from almost three decades of authoritarian military rule. It emerges that the task of fostering social transformation through the “weakest” branch seriously tasks the institutional integrity of the judiciary.

Neuropeptide Y (NPY) and NPY Y1 receptor in periodontal health and disease

Abstract
OBJECTIVES:
Neuropeptide Y (NPY) coordinates inflammation and bone metabolism which are central to the pathogenesis of periodontitis. The present study was designed to determine whether NPY was quantifiable in human gingival crevicular fluid (GCF) and to test the null hypothesis that GCF levels of NPY were the same in periodontal health and disease. A subsidiary aim was to determine the potential functionality of released NPY by detecting the presence of NPY Y1 receptors in gingival tissue.
DESIGN:
The periodontitis group consisted of 20 subjects (10 females and 10 males) mean age 41.4 (S.D. 9.6 years). The control group comprised 20 subjects (10 females and 10 males) mean age 37.4 (S.D. 11.7 years). NPY levels in GCF were measured in periodontal health and disease by radioimmunoassay. NPY Y1 receptor expression in gingival tissue was determined by Western blotting of membrane protein extracts from healthy and inflamed gum.
RESULTS:
Healthy sites from control subjects had significantly higher levels of NPY than diseased sites from periodontitis subjects. NPY Y1 receptor protein was detected in both healthy and inflamed gingival tissue by Western blotting.
CONCLUSIONS:
The significantly elevated levels of NPY in GCF from healthy compared with periodontitis sites suggests a tonic role for NPY, the functionality of which is indicated by the presence of NPY Y1 receptors in local gingival tissue.
